Euthanasia: Death and Medical Staff

â€Å"A dying man needs to die, as a sleepy man needs to sleep, and there comes a time when it is wrong, as well as useless to resist.† -Steward Alsop, Stay of ExecutionThough no one has a choice in their own birth, should we be entitled to a choice when it comes to our death? Therefore, what is Euthanasia? Euthanasia refers to the practice of intentionally ending a life in order to relieve pain and suffering; sometimes called â€Å"mercy killing.† Euthanasia has been one of the most controversial issues in the medical field.As of today, Euthanasia is only legal in three countries: namely Netherlands, Belgium and Luxembourg; and illegal in all countries remaining. Though it is illegal here in the Philippines, the researcher brought this topic out of curiosity with the issue.Why the researcher chose this topic: The researcher chose this topic to gain and give knowledge on Euthanasia; to give enlightenment to people whether to accept or to oppose Euthanasia.Statement of t he problemThis study entitled â€Å"Perception of selected medical staff on Euthanasia†, will give enlightenment to the certain questions that arise: 1. What is Euthanasia? 2. What are the perceptions of selected medical staff on Euthanasia? 3. A right to life or a right to die?Significance of the studyThe significance of this study is to give enlightenment to the following people:Respondents. Upon or during answering the questionnaire, they themselves  will ponder on the issue at hand. Students. Since euthanasia may seem to be an unfamiliar word to most of the students, this study will impart them knowledge about euthanasia. Administration. This study will both impart them more knowledge and also let them ponder on their own thoughts about euthanasia. Citizens. As a whole, they will be gaining more insight and understanding on the issues from euthanasia.Scope and delimitationThis study will only cover the professional medical opinion of doctors, and anyone in the medical f ield, and also the opinions of the society on Euthanasia. Definition of terms Euthanasia – the practice of intentionally ending a life in order to relieve pain and suffering.

The Rate Of Photosynthesis

1) Construct a graph of your data 2) Using the graph, estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to 26/50 leaf disks. 3. What variable were you testing in this investigation? We were testing the leaf disks as the control.The white light, and the water were the controlled variables. 4. Explain why the leaf disks started to float after being exposed to white light. The leaf disks started floating after being exposed to white light because the process of photosynthesis is light- dependent. Light is required for the process of photosynthesis to begin and so the disks would not start floating unless they were placed under the sun, or in this instance the white light. 6 . In this investigation, you measured the rate of oxygen production. How might you measure the rate of loss of carbon dioxide?The rate of oxygen production was measured by the amount of dicks that stated to float at a certain time. After the disks have all floated to the top, the rate of carbon dioxide loss could be measured by how long it takes for the leaf disks to float back down to the bottom. 7) Brainstorm possible environmental factors that could affect the rate of photosynthesis. Do research on one of these factors and write a short paper on your findings. Factors that could affect the rate of photosynthesis could be the duration of wavelength, high light intensity, or even air pollutants.The topic we researched was ‘High Light Intensity†. High light intensity happens beyond saturation point. Light intensity reduces the rate of photosynthesis. This affect is called solarization. It can be caused by photo-inhibition and photo-oxidation. Photo-inhibition and photo-o xidation occurs when shade leaves are abruptly exposed to bright light or when sun leaves are exposed to bright light with environmental stresses such as water deficit or extreme temperatures. Both occur when the energy absorbed by the photosynthetic reaction centers exceeds the ability to use that energy in metabolic activity.

Shop Organization [pic] BLACK SMITH AND HEAT TREATMENT INTRODUCTION Smithing is understood to handle relative small jobs only such as can be heated in an open fire or hearth. The shop in which the work is carried out is known as smithy’s or smithy shop and various operation are performed by means of hand hammer or small power hammers.Forging refers to production of those parts which must be heated in a close furnace. The portion of work in which forging is done is termed as the forge and work is mainly performed by means of heavy hammers, forging machines and presses. Shaping of metal is done either by steady comp ression or by impact between hammer and anvil after heating it above recrystallisation temperature in forging. Forging can be defined as the controlled plastic deformation of metal at elevated temperature in to a predetermined sizes and shapes using compressive forces exerted through some type of die by a hammer, a press or an upsetting machine.The B. S. H. T. shop is divided as:- 1. Draw gear section 2. Buffer section 3. Spring section INSTALLATIONS 1. Pneumatic power hammers (5 nos. ) 250 kg. Capacity-2nos. 500 kg. Capacity-1nos. 1000 kg. Capacity-2nos. 2. Hydraulic presses (3 nos) 3. Combined shearing, punching and nibbing machine (1 nos) 4. Spring testing machine (2 nos. ) 5. Air blowers (2 nos. ) 50 h. p. 6. Grinder (1 nos. ) 7. Circular saw (1 nos) 8. Power hacksaw (1 nos ) 9. Furnace (6 nos) 10. Shot peening machine (1 nos) 11. Tension (proof load ) testing machine (1 nos) PNEUMATIC POWER HAMMER:-The hammer has two cylinders compressor cylinder & ram cylinder. Piston of compr essor cylinder compresses air and delivers it to the ram cylinder where it accelerate the piston, which is integral with ram delivering the blows to the work. The reciprocation of the compression piston is obtained from a crank drive which is powered from a motor through reducing gear. The air distributor device between the two cylinders consist of rotary valves with parts through which air passes into the ram cylinder, blows & above the piston, alternatively. This drives the ram up & down respectively. HYDRAULIC POWER PRESS:-In power press the ram is driven by power instead of hand as in the case of hand press , The principal of a typical forging press is as follows:- The fluid passes first from a large capacity tank to a pump and then is delivered on the press with the aid of an accumulator and distributor at a pressure of at a pressure of at 200 to 300 kg/cm. The accumulator fluid pressure flows into to main cylinder and pressure on the top of the large piston. Since the cross-se ction area of the piston in the main cylinder is large, the press ram is forced down upon the material to be forged which lies on the anvil with high total power.Each power stroke the large piston is returned into its initial position by action of the working fluid on the piston rod in the pull back cylinder. To perform this motion, a relatively lower fluid pressure, but a large volume of water per unit time is required to accelerate the return stroke. FURNACES: The job is heated to correct forging temperature in a hearth or furnaces. The gas and oil are economical, easily controlled and most widely used fuels. In workshop, we used coal and crude oil as fuel forge furnaces are built so as to ensure a temperature up to 1350 degree centigrade in their working chamber.Two types of furnaces are used in this shop:- 1. Coke fired furnaces 2. Coal fired furnaces In cock furnace coke is used as fuel. In oil fired furnaces diesel is used as fuel. Diesel is sent by cast iron pipes from diesel tank in an injector and compressed air is sent on high intensity by a blower. The air jet mixed with diesel is used as fuel in oil fired furnace. Furnace are used to red hot the raw material to the required temperature. Fuel is injected into these furnace with a great pressure associated with air blast. This high pressure is generated by centrifugal air compressor, which is situated in the shop itself.This compressed air from the compressor is then taken to several furnaces through the underground pipes. One man is present near the furnace that puts the raw material and takes out the red-hot material, which is then placed under power hammer. After acquiring the required shape, these products are either hardened by various hardening procedures or simply cooled to the atmospheric temperature. Draw Gear Section:- The draw gear and screw coupling are used to connect two coaches to each other. These are designed for a proof load of 75tones and breaking load of 130t.The components are sp ecially heat treated to achieve the load bearing capacity. In maintenance procedure of draw gear and screw coupling stress relieving is done. The components made of st 60-61 are to be stress relived and the new material introduced for draw gear IS: 5517-93 Grade35Mn6M03 is not to be heat treated. The maximum temperature up to which draw gear can be heated is 550 C. Buffer Section:- Buffers are used to absorb the shock during impact action of coaches. Apart from absorb the impact energy it also guide the coaches to align in track during turn on curvature.Each buffer has capacity of 1030 kg-m with a total stroke of 127 mm. Rubber springs are used in this buffer assembly so it have low absorption capacity in earlier part of the stroke which rises rapidly towards the end resulting in absorption of high shock loads and transmitting of minimum end pressure to under frame. Components of buffer assembly: ? Buffer casing (cast steel) ? Buffer plunger (cast steel, forged) ? Rubber buffer pads ? Buffer spindle ? Destruction tube ? Recoil spring ? Recoil spring parting plate ? Buffing spring parting plate ? Recoil spring washer ? Face plate for buffer plunger M-24 Hex head bolt Spring Section:- The springs are used in the bogie for the suspension system of coaches. There are two types of suspension as primary and secondary suspension. The springs classified to primary and secondary system by the load carried by them. Fig: Inspection procedure:- Inspect all components visually for dimensional distortion and surface defects such as cracks, wear, dent marks and pitting etc. Remove scale, rust, light cracks by grinder. Stress relieving. In case of doubt of cracks dye penetration or magna flux machine is used to check the cracksLoad test is done on load testing machine for 100t to 150t. In all this procedure if component is find ok then it is dispatched to the assembly. ROLLER BEARING In passenger coaches of Indian Railway system, only single bearing type axle box arrangement is used, means only two bearing are used to support the axle. The bearing used for this purpose is of Spherical Type Roller Bearing. CONSTRUCTION:- Spherical roller bearing consist of an outer ring having a spherical race way within which two rows of barrel shaped rollers operate. These rollers are guided by an inner ring with two raceway separated by a center rib.This bearing has self alignment. Spherical roller bearings have a large capacity for radial loads, axle loads in either direction. Spherical roller bearing no. 22336/c3 with 130 mm parallel bore on the inner ring are being used on ICF type coaches. They are directly shrunk fit on the axle journals. These roller bearings are to be inspected periodically as per schedule. Fig: TOOLS AND PLANTS FOR MAINTENANCE OF ROLLER BEARING:- |S. no. |Function |Equipment used | |1. Cleaning of roller bearing |3 stage cleaning plant or pre wash, wash & water rinsing | |2. |Dismounting of spherical roller bearings |Hydraulic dismounting equ ipment-withdrawal nut | |3. |Mounting of roller bearings |Induction heater with demagnetizing device | |4. |Securing of end locking bolts |Torque wrench | |5. |Visual inspection of demounted roller bearings |Magnifying glass with light | |6. Checking of radial clearance |Long feeler gauge | |7. |Measurement of journal |Outside micrometer | | | | | | | | | DISMOUNTING OF BEARING:- ? For dismounting of bearings, special hydraulic dismounting equipment is used.This machine injects oil between the journal and bore to the inner ring with high pressure which expands inner ring resulting in breaking of interference. The bearing becomes loose on the journal and slides over it. The bearing is then removed from the journal and sent to the cleaning plant. ? All components of bearing such as inner ring, outer ring, rollers, and cage are examined for cracks, damage and breakage. If bearing is found free from all the defects mentioned above, the radial clearance is measured with feeler gauge. R adial clearance is not within prescribed limits, the bearing is rejected.RECOMMENDED RADIAL CLEARANCE LIMITS FOR BEARING IN DISMOUNTED CONDITION: |Bearing make |Radial clearance | |SKF |0. 105 to 0. 296 mm | |NBC |0. 080 to 0. 190 mm | MOUNTING OF BEARING:- ? Before mounting the bearings, it is checked that journal and shoulder diameters are within permissible limits. All direct mounted spherical roller bearing have interference fit with axle journal, therefore it requires heating and shrinkage fitting. Heating of bearings is done by using an induction heater. Fig: ? Temperature range for heating the bearing is 100 to 120 centigrade. ? Induction heating is a quick, safe, energy saving and environment friendly process. In this system, bearing is short circuited to perform as a secondary winding whereas the core winding is at primary side. Bearing is placed around a yoke. Due to principal of induction current, bearing is heated due to its electrical resistance and attains the desired temperature. It is recommended to set the machine in such a way that it takes 5 to 7 minutes to attain the temperature of 120c maximum of bearing. ? Heated bearing mounted on journal with the help of hook and it is positioned by giving light taps with plastic hammer. BEARING IS REJECTED FOR THE FOLLOWING DEFECTS: ? Pitted or flaked roller tracks and rollers. ? Cracked or deformed or badly worn out cage ? Cracked inner or outer ring ? Scored or damaged outer surface of the outer ring. ? Indentation or rings or rollers ? Scoring of roller tracks or rollers ? Corrosion damage Excessive or less radial clearance CORROSION SHOP ICF coaches incorporate a no. of pressed steel sections made of thin sheets (1. 6, 2. 0, 2. 5, & 4 mm) and plates of thickness 5 to 16 mm in the construction of the shell. These sheets are considerably stressed as the design of the coaches is based on the principle of a self supporting structure and it is essential that these coaches are maintained in good conditi on free from corrosion. Corrosion is take place when a steel surface comes in contact with moisture. For prevention the corrosion, film of paint is coated on steel surfaces.In addition to it, application of an inhibite Zinc Chromate Red Oxide Primer is done to prevent the surfaces coming in contact with atmosphere. Surfaces which are not finish painted have also been given ? coats of bituminous emulsion which gives added protection to the steel surfaces by excluding moisture along with primer. If due to some reason like abrasive action of sand, the bituminous film brake down, the inhibitive primer acts as a second line of defence. Corrosion of steel surfaces starts only when both the bituminous and the primer suffer mechanical injury.Corrosion is indicated by: ? Flaking of paints ? Flaking of metals ? Pitting and rusting Corrosion can be classified into two categories as vulnerable and not vulnerable. Vulnerable corrosion of parts means, the parts are fully corroded and they should be changed for further operation. The examples of vulnerable members in coaches are tubular frame below lavoratories, trough floor in bays, sole bar, body pillars etc. Not vulnerable parts mean the parts which are corroded to little depth and they may be use still by treatment of corrosion.The examples of mot vulnerable members are head stock inner and outer along with stiffening tubes, roof sheets, body side doors, partition walls, water tank ceiling construction, battery box etc. All the components of coaches are examined in following way for corrosion:- ? Visual inspection ? By spiked hammer ? In the inner surfaces by making g the holes in corresponding component. ? If the components are corroded excess as prescribed limit then change the component by new one. ? And if the component is not so much corroded then repair the component by scrapping old coats of paint and make new coats of paints of anticorrosive layerBRAKE GEAR SHOP Presently coaches are mounted with air brake system instead of vacuum brake system due to better braking application. The air brake used is TWIN PIPE GRADUATED RELEASE AIR BRAKE SUSTEM. In this system two pipes known as feed pipe and brake pipe are used, instead of that there are two brake cylinder on each bogie, one auxiliary reservoir, a distribution valve, a control reservoir etc. The air brake system uses compressed air supplied by the main reservoir in locomotive. The locomotive compressors charge the feed pipe throughout the length of the train .The feed pipe is connected to the auxiliary reservoir and the brake pipe is connected to the brake cylinder through the distributor valve. Brake application takes place by dropping the pressure in the brake pipe. Charging the brake system †¢ Brake pipe throughout the length of train is charged with compressed air at 5 kg/cm2 †¢ Feed Pipe throughout the length of train is charged with compressed air at 6 kg/cm2 †¢ Control reservoir is charged to 5 kg/cm2 †¢ Auxiliary reservoir is charged to 6 kg/cm2 Brake application stage For brake application the brake pipe pressure is dropped by ventilating air from the driver’s brake valve.Subsequently the following actions take place †¢ The control reservoir is disconnected from the brake pipe. †¢ The distributor valve connects the auxiliary reservoir to the brake cylinder and the brake cylinder piston is pushed outwards for applications of brakes. †¢ The auxiliary reservoir is however continuously from feed pipe at 6kg/cm2 |Description |Reduction in B. P Pressure | |Minimum Brake application |0. 5 to 0. kg/cm2 | |Service Brake application |0. 8 to 1. 0 kg/cm2 | |Full service Brake application |1. 0 to 1. 5 kg/cm2 | |Emergency Brake application |Brake pipe is fully exhausted and its pressure reduces | | |to almost zero. | Brake release stage: Brakes are released by recharging brake pipe to 5 kg/cm2 pressure through the driver’s brake valve. ? The distributor valve isolated the brake cylinder from the auxiliary reservoirs. ? The brake cylinder pressure is vented to atmosphere through DV and brake cylinder moves inwards. [pic] BRAKE CYLINDER Every coach fitted with air brake system, have two brake cylinders for actuating brake rigging for the application and release of brakes. During application of brakes the brake cylinder develops mechanical brake power by outward movements of its piston assembly, by receiving air pressure from auxiliary reservoir through the distributor valve.This mechanical power is transmitted to the brake shoes through a combination of levers. During release action of brakes the compression spring provided in the brake cylinder brings back the rigging to its original position. The cylinder body is made out of sheet or cast iron and carries the mounting bracket, air inlet connection rib and flanges to the cylinder body a dome cover is fitted with the help of bolts and nuts. The dome cover enclosed the spring and passage for the piston trunk which is connected to the piston by screws.The piston is cast iron having a groove in which piston packing is seated . piston packing is of oil and abrasion resistant rubber material and is snap fit to the piston head. The packing as self lubricating characteristic which ensure adequate lubrication over a long service period and extends seal life considerably. AUXILARY RESERVOIR The auxiliary reservoir is a cylindrical vessel made of sheet metal. On both the ends of the reservoir, flanges are provided for pipe connections. One end of the auxiliary reservoir is charged through the feed pipe to a pressure of 6 kg/cm2 .At the bottom of the auxiliary reservoir, a drain cock is provided for draining out the condensate/moisture . The auxiliary reservoir should be overhauled in every POH. DISTRIBUTOR VALVE Distributor valve is the most important functional component of air brake system and is also referred as the heart of air brake system. The distributor valve sense drop and rise i n brake pipe pressure for brake application and release capacity. It is connected to the brake pipe through branch pipe.Various other components connected to the distributor valve are auxiliary reserve reservoir, brake cylinders and control reservoir. FUNCTION OF DISTRIBUTOR VALVE For application and release of brakes the brake pipe pressure has to be reduced and increased respectively with the help of driver’s brake vale. During these operations the distributor valve mainly performs the following function. i) Charges the brake system to regime pressure during normal running condition. ii) Help in graduated brake application, when pressure in brake pipe is reduced in steps. ii) Helps in graduated brake release, when pressure in brake pipe is increased in steps. iv) Quickly propagates reduction of pressure in brake pipe throughout the length of the train by arranging additional air pressure reduction locally inside the distributor valve. v) Limits maximum brake cylinder pressu re for full service applicationemergency application. vi) Control the time for brake application and brake release depending on service conditions. vii) Facilitates complete discharge of air from the air brake system manually with the help of operating lever. iii) Protects overcharging of control reservoir when the brake pipe pressure is quickly increased for releasing the brakes. C3W DISTRIBUTOR VALVE The C3W distributor valve consists of: 1) Main body 2) Quick service valve 3) Main valve 4) Limiting device 5) Double release valve 6) Auxiliary reservoir check valve 7) Cut off valve 8) Application choke 9) Release choke OPERATION OF C3W DISTRIBUTOR VALVE For effective functioning of air brake system, the distributor valve has to operate effectively during 1) Charging stage 2) Application stage 3) Release stage 1) CHARGING STAGEDuring charging stage the compressed air flows from the brake pipe and enters into the brake pipe chamber of main valve, cutoff valve and quick service valve. Due to this pressure the various valve get activated and perform as under MAIN VALVE Due to brake pipe pressure acting on top face of the large diaphragm, differential pressure acts on the main valve. As a result the hollow stem moves downward there by connecting brake cylinder to atmosphere. In addition these because of BP pressure at top of large diaphragm it press ring and trigger. This action unlocks the CR release valve by raising upward the locking rod.CUT OFF VALVE As brake pipe pressure enters into the cut off valve it flows through the solex jet and valve, (which is held upon due to action of BP pressure on bottom side of the lower diaphragm) to the control reservoir, as the CR & BP pressure equalizes, diaphragm assembly comedown and valve reach to lap position. The control reservoir pressure now also reaches to the upper portion of top diaphragm of quick service valve and the bottom portion of large diaphragm of main valve simultaneously, the auxiliary reservoir is charge d with BP pressure reaching from cut off valve chamber- via auxiliary reservoir check valve. ) APPLICATION STAGE EMERGENCY APPLICATION During emergency application the brake pipe pressure is reduced rapidly to 0 kg / cm2 by the driver’s brake valve. Because of this drop the position of the various valves will be as described below. MAIN VALVE: With drop in BP pressure to 0 kg / cm2 differential pressure acts across the large diaphragm. As a result the hollow stem is moved in upward direction and pushes the check valve there by opening the passage for entry of auxiliary reservoir pressure at top portion of main valve. This pressure then gets a way to break cylinder through limiting device.The brake cylinder thus gets charged with the compressed air. This pressure is known as BC-pressure. LIMITING DEVICE The auxiliary reservoir pressure, which entered into the top position of main valve, now enters the limiting device through the valve, which is held open. From limiting device air pressure now enter the brake cylinder. When the BC pressure rises to 3. 8 kg / cm2 the upwards force on the diaphragm lifts the guide and the valve at the bottom of the limiting device gets closed. Thus further entry of air into the brake cylinder stops. When the brake cylinder pressure reaches 3. kg / cm2 this pressure i. e. BC pressure act on Top face of small diaphragm of main valve ? Bottom face of upper diaphragm of cut off valve ? Top (small chamber) of quick service valve Now because of this BC pressure acting at main valve small diaphragm, the hollow stem is pulled down. As a result the check valve at top comes down to close stage and assume lap position with the hollow stem closing further entry of AR pressure. CUT OFF VALVE: In cut off valve the bottom face of the upper diaphragm is subjected to BC pressure because of which guide is lifted.Also the upper portion of lower diaphragm is subjected to CR pressure, which pushes the total assembly downwards. This action close s the valve off cut off valve, these by isolating it from control reservoir pressure. QUICK SERVICE VALVE In quick service valve BC pressure acts at the top of valve and control reservoir pressure act at top face of upper diaphragm, As a result the stem is pushed down BP pressure inside the DV is at â€Å"0† kg / cm2 the residue BP pressure from the bulb of quick service valve will flow back and vent to atmosphere with the BP line.GRADUATED APPLICATION During graduated brake application the brake pipe pressure is draped in steps by driver is brake valve. The movement of various valve assemblies is almost in the some direction as during emergency application, but their movement is comparatively less. In the main valve however after each application the hollow stem assumes the lap position with the check valve. In addition to this during graduated application the bottom valve of limiting device is held open to allow compressed air to enter into brake cylinder. When BC pressure reaches 3. kg / cm2 the bottom valve in the limiting device gets closed, similarly at the time of full service application as the BC pressure reaches 3. 8 + 0. 1 kg / cm2 within specified time, the position of various valve assemblies will be the same as described above. 3) RELEASE STAGE When the brake pipe pressure is increased in steps for graduated release of breaks the position of different valve is as described below. MAIN VALVE At the top face of large diaphragm as the BP pressure increases, the hollow stem is moved down ward leaving its lap position with check valve.The BC pressure thus finds a passage from top of hollow stem to exhaust to the atmosphere. This action reduces pressure on top of the upper diaphragm and the hollow stem engine lifts up to lap position. It closes the hollow stem top portion. The some cycle is repeated when BP is increased during next stage. In this way graduated release effect is obtained. CUT OFF VALVE; As the BP pressure increase the position of cut off valve remains similar as in graduated application i. e. the cut off valve will remain close isolating CR pressure from brake pipe pressure. QUICK SERVICE VALVEWhen the BP pressure is increased then as explained above from the main valve the BC pressure gets exhausted to atmosphere. This action gradually reduces the BC pressure. When BC pressure reduces to 0. 8 kg / cm2 during brake release, the force at the top of the quick service valve, becomes comparatively less than BP pressure present in Quick service valve. As a result the valve at top gets lifted thereby giving passage to blocked BP pressure to atmosphere with the exhaust of BP pressure the quick services valve of the distributor valve again gets ready for next brake application. MANUAL RELEASEDouble release valve provides for accelerated manual brake release when is particularly useful during shunting operation. A short pull on the lever of double release valve is all that is needed. This action opens the control re servoir release chock valve, which is then held open by the locking rod, venting control reservoir through the open control reservoir release check valve brings the main valve to release position and exhaust the brake cylinder pressure through the hollow stem. PASSENGER EMERGENCY ALARM SYSTEM It consists of two components: 1. Passenger emergency alarm signal device (PEASD) 2. Passenger emergency alarm valve(PAEAV)These two components in combination give an indication to the e driver that some passenger is in need to stop the train. The indication is transmitted from the coach when the passenger pulls the chain. Passenger Emergency Alarm Signal Device:- PEASD is a manually operated pilot vent valve. It is operated through mechanical force exerted by pulling the alarm chain provided inside the coaches for emergency use. Passenger Emergency Alarm Valve:- Passenger coaches are fitted with an alarm chain pull arrangement. Alarm chain is connected to the two PEASD which are situated at ei ther side of one end wall of the coach.PEASD’S are connected to the PEAV through a 10mm control pipe. BP pressure is fed to the PEAV through a 20mm branch pipe, in the event of alarm chain pull air is depleted form the control pipe connecting PEAV and PEASD causing BP pressure to exhaust through the 4 mm choke in the PEAV. This causes partial application of brakes. This drop in pressure in the brake pipe line is also observed in flow meter fitted in the locomotive for the driver to stop the train. LIFITING SHOP The main constructional and design feature of the ICF/RCF all-coil bogies, used on mainline BG coaches are briefly described as follows: |S. No. Description |Parameters | |1 |Maximum Axle load bearing |16,25t,13t | | |capacity | | |2 |Wheel base |2896 mm | |3 |Wheel Diameter |915 mm | |4 |Axle guidance |Telescopic axle guide with oil damping | |5 |Primary suspension |Coil spring | |6 |Secondary suspension |Coil spring | |7 |Shock absorbers |Vertical dashpot in prim ary suspension | | | |Hydraulic double acting vertical shock | | | |Absorber in secondary suspension. |8 |Transfer of coach body weight |Through bogie side bearer pitched | | | |at 1600mm | ALL-COIL ICF BOGIE The bogies being currently manufactured by ICF/RCF which have been accepted as standards of the Indian Railways and are of an all welded light weight construction. Axles are located on the bogie by telescopic dash pot and axle guide assemblies. Helical coil springs are used in both the primary and the secondary stages. The axle guide device provides viscous damping across primary springs while hydraulic dampers are provided across the secondary stage.Dampers are protected against misalignment by resilient fittings. Isolation of vibration is effected by rubber pads in primary and secondary suspension. Deflection due to the tare weight is almost equally divided between axles and bolster springs. Weight of coach body is transferred to its bogie by side bearers consist of lubricate d metal slides immersed in oil baths. No vertical weight transfer is affected through bogie pivot and the pivot acts merely as a centre of rotation and serves to transmit tractive / braking forces only. BOGIE ASSEMBLY The bogie frame and components are of all-welded light construction with a wheel base of 2. 896 metre.The wheel sets are provided with self-aligning spherical roller bearings mounted in cast steel axle box housings. Helical coil springs are used in both primary and secondary suspension. The weight of the coach is transferred through side bearers on the bogie bolsters. The ends of the bogie bolsters rest on the bolster helical springs over the lower spring beam suspended from the bogie frame by the inclined swing links at an angle 70 . Hydraulic shock absorbers and dash pots are provided in the secondary and primary suspensions respectively to damp vertical oscillations. AXLE BOX GUIDE WITH DASH POT ARRANGEMENT Axle box guides are of cylindrical type welded to the botto m flanges of the bogie side frame with close dimensional accuracy.These guides together with lower spring seats located over the axle box wings house the axle box springs and also serve as shock absorbers. These guides are fitted with guide caps having nine holes of diameter 5 mm equidistant through which oil in the lower spring seat passes under pressure during dynamic oscillation of coach and provide necessary damping to primary suspension to enhance better riding equality of coach. This type of rigid axle box guide arrangement eliminates any longitudinal or transverse relative movement between the axles and the bogie frame. The quantity of oil required to achieve 40 mm oil lever above the guide cap in modified arrangement is approximately 1. 6 liters and in unmodified arrangement is approximately 1. 4 litters. AIR VENT SCREWSOn the bogie side frames, directly above the dash-pots, tapped holes are provided for replenishing oil in the dash pots. Special screws with copper asbestos washers are screwed on the tapped hole to make it air light. BOGIE BOLSTER SUSPENSION The bolster rests on the bolster coil springs- two at each end, located on the lower spring beam which is suspended from the bogie side frame by means of bolster-spring-suspension (BSS) hangers on either side. The two anchor links diagonally positioned are provided with silent block bushes. The links prevent any relative movement between the bogie frame and coach body. SPRINGS In ICF bogie, helical springs are used in both primary and secondary suspension.The springs are manufactured from peeled and centre less ground bar of chrome vanadium/chrome molybdenum steel conforming to STR No. WD-01-HLS-94(Rev. 1) CENTRE PIVOT ARRANGEMENT The centre pivot pin joins the body with the bogie and transmits the tractive and braking forces on the bogies. It does not transmit any vertical load. It is equipped with rubber silent block bushes which tend to centralize the bogies with respect to the body and, to some extent, control and damp the angular oscillations of the bogies SIDE BEARERS The side bearers are provided to support the weight of the coach. It consists of a machined steel wearing plate immersed in an oil bath and a floating bronze-wearing piece with a spherical top surface kept in it, on both sides of the bogie bolster.The coach body rests on the top spherical surface of these bronze-wearing pieces through the corresponding attachment on the bottom of the body-bolster. The whole arrangement is provided with a cover to prevent entry of dust in the oil sump. ANCHOR LINKS The floating bogie bolster which supports the coach body is held in position longitudinally by the anchor links which are pinned to the bolster sides and the bogie Transoms. One anchor link is provided on each side of the bolster diagonally across. The links can swivel universally to permit the bolster to rise and fall and sway side wards. They are designed to take the tractive and braking forces. The anchor link s are fitted with silent block bushes SILENT BLOCKThis is a synthetic rubber bush fitted in anchor link and center pivot of ICF bogies to transmit force without shock and reduce noise. EQUALISING STAYS This Device has been provided on bogies between the lower spring plank and the bolster to prevent lateral thrust on the bolster springs which have not been designed to take lateral force. These links have pin connection at both ends and therefore can swivel freely. BOLESTER SPRING SUSPENSION HANGERS (BSS HANGERS) In the secondary suspension the bolster is supported on helical coil springs which are placed on the lower spring plank is suspended from the bogie side frame through BSS hanger on hanger blocks. SHOCK ABSORBERSHydraulic shock absorber is also provided to work in parallel with the bolster springs to facilitate damping for vertical oscillations. WORKSHOP MAINTENANCE- BOGIE SHOP 1. Coach Lifting 2. Bogie cleaning 3. Bogie dismantling 4. Component cleaning 5. Attention to compon ents 6. Repair of components 7. Bogie assembly 8. Load testing and adjustment 9. Lowering of coach 10. Final adjustment OBJECT:- To study inspection & testing procedure of helical spring of coaches also suggest methods of improvement to reduce rejection & prevention from corrosion. USE OF SPRINGS:- Springs are used in the suspension system of coaches to absorbs the jerks developed during running of coach and provide comfort to the passengers. INSPECTION OF SPRINGS:- Springs are inspected during every POH.The inspection procedure is as follows: ? Springs which are lowered from the bogie are sent for the washing in spring section. Here the springs are dipped in the caustic soda tank for 12 to 16 hrs. so the oil, grease, scale etc are cleaned. ? Springs are then washed by the water jet. ? Visually inspect the springs for breakage, welding marks, cracks and corrosion pits. ? Shot peening for surface finish and fatigue relief of springs. ? Cracks are tested in magna flux machine. ? Codin g of springs ? Anti corrosive coating of red oxide, and painted. ? Load test ? Grouping SHOT PEENING:- Shot peening is done for the surface finish and fatigue relief of springs.In shot peening process small particles of chilled iron are blasted on the springs with high velocity, so these particles works as abrasive and take away a fine layer of metal with it. And the surface of springs looks clean. Rotary Table Type Shot Blasting machine is used for the shot peening process. This machine has two tables which alternately loaded by springs. The max. dia of job is 1800 mm and load carrying capacity is 2500kg.. At a time 25 axle box springs or 18 bolster springs can be shot peened by the machine. TESTING OF CRACKS:- It is nondestructive method of testing. Magna flux machine is used for detection of cracks in spring. The spring is first bathed by the solution of flouroscent, iron powder and kerosene.Then the springs are magnetized by the machine with clamping in machine itself. When the springs are magnetized, the springs are lightened by the ultraviolet lamp. Since the process is done in the dark room, so if the springs have cracks then this flouroscent shines which penetrated in the springs due to crack ness and detection of cracks is done so the spring will rejected. LOAD TEST:- After coding and coating of paint the springs are sent to the load test. The springs are tested for the 2000ton load and this load is kept for 1 to 2 minutes. If the springs can sustain this load with limited deflection then springs are selected else rejected. METHODS OF IMPROVEMENT:- Use the springs made of standardized material as suggested by Railway’s Standard. ? The springs should be made of fine grained spring steel. ? Use the springs manufactured by the authentic company and also notice the manufacturing process of springs should be according to the standardized method. ? 100% of springs should be checked for all the test procedure. PREVENTION FROM CORROSION:- Springs shoul d be coated with the anticorrosive paint and black bituminous paint. ———————– Technician 2 Technician 1 Senior technician Supervisor Supervisor Junior Engineer 2 Junior Engineer 2 Junior Engineer 1 Junior Engineer 1 Section Engineer Senior Section Engineer (SSE) Helper

Describe an epidemic disease and how it may change the preparation of Essay

Describe an epidemic disease and how it may change the preparation of the bodies for funeral services - Essay Example In 1990 once again a similar type of virus was spotted among monkeys in Reston, Virginia which were imported from the Philippines. The strain was named Ebola Reston (EBO Reston). The epidemic continued to emerge in the region in different countries such as in Zaire in 1995 and 2003, Gabon in 1994, 1995 and 1996 and Uganda in the year 2000. In 1994 a subtype of Ebola virus was spotted in the Ivory Coast and was identified as Ebola-CI. So far there have been 1500 identified cases of Ebola virus in the world out of which two third have died. King (2003) further states that the virus is one of the 18 least known viruses that have the capability of causing viral hemorrhage fever syndrome. The virus belongs to the family of flaviviridae. There are four subtypes of Ebola Virus. They are Ebola Zaire, Ebola Sudan, Ebola Ivory Coast and Ebola Reston. Its outbreak is in the form of an epidemic that is capable of causing 88% deaths in the patients suffering from it. Ebola Zaire is considered to be the deadliest one with greatest number of deaths attributed to it. However no deaths were reported from the four cases of Ebola Reston. The virus is quickly replicated in human and non human tissues spreading the infection rapidly. The replication is followed by severe focal necrosis. The severest form of necrosis occurs in the liver where councilman like bodies are formed like the ones formed in the yellow fever. The tissues and blood of the near death patients suffering from Ebola virus are highly infectious. King (2003) states that in 1996 members of the National Institute of Virology of South Africa carried out a research in Zaire to find out the infectivity of the virus in different species of plants, vertebrates and invertebrates. It was observed that the serum and feces of the insectivorous bats (Tadarida pumila) and fruit bats (Epomophorus wahlbergi) were found to help the virus multiply rapidly without dying.

Segmentation and Targeting Essay Example | Topics and Well Written Essays - 750 words

Segmentation and Targeting - Essay Example Starbuck has experienced tremendous growth since it was founded. Identify the company’s target market and positioning strategy The level of coffee consumption in the United States has been on a downward trend, especially in the late twentieth century. However, Starbuck has been quite cautious when choosing its target markets. A target market can simply be defined as a group of consumers who share the same interests that a particular company selects to serve. The process of choosing a target market can be undertaken by evaluating social, environmental, political, and competitive factors. Consumers bargaining power and entry barriers all fall under the category of market factors. The prices offered by Starbucks were extremely high and the company was trying to develop a new culture for its customers. Considering that Starbuck was very careful when it came to coffee production, the company managed to maintain a stable relationship with its suppliers hence, it faced minimal threat s and competition (Starbucks Corporation SWOT Analysis, 2008). Office employees with both middle and high revenue were the sole target for Starbuck. Schultz wanted Starbuck to be the place where people could meet and relax on their way home, after work and socialize with each other. Therefore, the company was aggressive in meeting the needs of the consumers. Great consideration was also placed on the arrangement of the store. Target market can be executed in various ways namely concentrated, distinguished and undistinguished (Kotler & Armstrong, 2004). The concentrated strategy focuses its efforts on a single market section and develops and maintains an exclusive approach for every section. The distinguished approach reaches out to the market by creating distinct products and promoting the programs for the various sections. The undistinguished strategy on the other targets the whole market using a single (Kotler & Armstrong, 2004). Starbuck adapted the undistinguished strategy to ma rket their products. The company measured the whole market as one single section. The main obstacle that Starbuck faced when it employed this strategy is the development of a brand that would satisfy the needs of all customers. Nevertheless, Starbuck did not compromise any of its services hence, they did everything they could in order to produce a quality product. A company must choose which position it wishes to occupy in the market after identifying its target. The positioning entails the way consumers define a particular product in terms of quality, size, price and performance and several other factors. Previously, Starbuck had been using transactional marketing where profit was obtained mainly from reserved customers who had a long-term relationship with the company. However, the customer retention approach aims at enchantment instead of consumer fulfillment. Starbuck later discovered that public opinion was a better approach. This kind of strategy takes a long time to thrive, t hough the benefits are worthwhile (Brassington & Pettit, 2000). How does their product line fit with their target market and positioning? Does it make sense? Starbuck began to create high quality products and services to its consumers. Schultz was aware of the fact that coffee is indeed perishable hence, he emphasized on the production of quality products by supervising each stage of coffee manufacture. Whole bean coffee was purchased from countries such as Kenyan and Ethiopia (Stanley, 2002). The coffee was then roasted and

However, I have come across a few instances which have raised a matter of concern for me as an employer. Though we as higher management are allowed to prohibit social media for employees during working hours, employees cannot be deterred from using during their break time. Strategies like placing a firewall access for social media sites or any other websites which can harm employee productivity can be used to improve the working measures. Such strategies will certainly not prove to be an illicit or illegal provision lawful and will certainly not be proved that an employer has conducted unfair labor practice over its policy and in this case, such labor policies should not be very broad and should not be administered in a manner which restricts or violate employee rights. Before we take any step or implement any policy, we have to be absolutely sure to consult it with our counsel and regulators and have to assess and analyze the use of such strategies. It is a fact that employees feel vulnerable if they perceive that their rights have been restricted by their employers or they are prohibited from certain activities without any elaboration or reason. Due to this reason, we have to implement certain policies and procedures which can implicate privacy issues but also helps us to mitigate any potential threats or risk which looms large over our organization. Such strategy will also help our organization to confirm that we have been able to make organizational media policies in a manner which are unbiased and are also irrational. Rules and policies which are ambiguous or irrelevant should be avoided and must not contain any words or sentences which indicate any sign that the rights of employees have been restricted or

Modern pricing models Essay Example | Topics and Well Written Essays - 250 words - 1

Modern pricing models - Essay Example Some of the shortcomings experienced with the Black-Scholes model were strike-price bias and return skewness. Consequently, the development of the Heston model came in as the best alternative tool for the purposes of advanced investments (Gilli, Maringer & Schumann 2011, p.257). As any other stochastic volatility model, the Heston model utilizes statistical methods when making calculations or forecasts of the various pricing options in consideration. As such, it also bases on the assumption that the underlying security or trading option has an arbitrary volatility. Therefore, the Heston model falls among the various different models of stochastic volatility such as the GARCH model, the Chen model, as well as the SABR model. Consequently, the Heston Model also falls under the standard smile model category, with â€Å"smile† in this concept referring to the volatility smile. A volatility smile is a graphical representation of various options that have identical expiration date expressing an increasing volatility. This increase in volatility arises often arises when the options become more out of the money or in the money. The concave shape generated by the graph is what gives rise to the name, the smiles model, as it appears like a smile (Wang 2007, p. 3). The Heston Model applies mathematical calculations in describing the process of evolution in volatility that an underlying asset undergoes under the stochastic volatility options. As such, just as other statistical models mentioned above, the Heston Model equally has a number of assumptions, such as the volatility of an asset not being constant, or deterministic, but rather following a random process. Some the of the basic assumptions of the Heston Model is that the stochastic process determines the asset price, St In addition, forms part of the Wiener Process as experienced under the GBM (Geometric Brownian Motion) also considered

The perspective of European Union in the future Essay

The perspective of European Union in the future - Essay Example In the year 2002, it was recommended that an additional 20 countries should join by the year 2004. This recommendation was made under the assumption that the Eastern Europe will take the European Union to new levels. The logic behind this is the fact that it will give access to new and larger markets, which will provide a means for the EU to cope in the present global economy. The question on many people’s minds is what the EU should be like in the future. Europe itself will have undergone a series of multi-dimensional changes in the future, with regard to social environment, economic strength, political priorities in addition to geopolitics. This essay will discuss the future of the EU and how it will influence solidarity, democracy, and liberty in the years to come. The term liberty is taken to carry two meanings according to the European act. The refers to the facilitating of the free flow of goods, the removal of barriers, flow of income and the flow of people, who are par t of the member countries (Smith, 2005). Analysts put forth the fact that there are very low chances of the international market turning into the prime focus of economic interests and engagement in the near future, since the EC has earned a longer life cycle. For instance, the anticipated gains in welfare among a number of the ECU 216 billion have been estimated to add up to 5.3 percent of the total GDP (Vendal, 2010). There is anticipation that virtually a cycle of benefits will be reaped, particularly in the long run. This is with regard to industrial reorganization, improved innovation, and economies of scale (Smith, 2005). Regardless of a bright future, there are chances that the community may run into internal speed bumps. The reason for this is the fact that it is presently made up of the a lesser grouping when it comes to the functionality of its members. An example may be inclusive of the fact that there is doubt as to whether there will be enough finances from the southern economies, which are regarded to be weak to enable them to participate in the EMU. It appears that a looser method of interaction is advised for the future community, especially for the enlargement of the community (Sampedro, 2004). Another aspect that is required for liberty to grow is openness accompanied with sudsier. Citizens ought to be informed of the remedies at their disposal of their rights are not taken into consideration. These remedies constitute ombudsmen, courts, and committees through which they can use to make petitions. A future Union should be a part of the people and the people should be a part of it. This means that the process of decision making should be open and the decisions should be made as often as possible to citizens (Natew, 2010). The citizens of all the members’ state expect a European Union whose administrations is candid, and regard accountability (Jacobi, 2001). There is no definite picture as what the enlarged EU it likely to be like, this i s however is not to suggest that the power of the convention should be underestimated. A significant share of the duties that are performed by the Union are legalistic and technical. Presently, efforts are directed towards increasing coherence, simplification and enhancement of transparency in the political and institutions bodies of the EU. There is a streamlining process that focuses on the rules of decision making and availing a number of alternatives when it comes to the creation of laws. (Jackson, 2007) Analysis however highlights the fact that simplification may be a political matter. For instance if a large share of

Should companies disclose to the people if they make digital Essay

Should companies disclose to the people if they make digital correction on advertisement - Essay Example I am sure this will be a good omen for the companies because they can easily come out in the open and make their point clear which indeed is significant towards their understanding domains. If the company makes a concerted effort, the digital correction on advertisements would mean that they have a better word of mouth overall and that the varied publics will speak highly of the company (Kadir 2013). It will also implicate for the company being truthful about its dealings and a sense of openness is easily visible across the board. Another reason why disclosure is all the more crucial for the sake of the companies is because digital correction on advertisements reveals their intent to come out in the open and that too without much difficulty. This is the reason why companies tend to be ethical more than anything else. This will be the basis of finding out how anomalies exist and how such nuances can be resolved in an amicable way (Westrup 2009). The disclosure does not mean that the company is looking to cover up its mistakes of the past yet there is an element of honesty attached with the disclosure which is all the more significant and reassuring from the companys perspective. Ladies and gentlemen, I am convinced that coming out clean is a better policy than making one mistake after the other. The digital corrections on advertisements stand as a honest policy which will win many favors by the people at the helm of affairs within the company levels. It leaves no stone unturned and addresses the problems which are faced by the organizations in their day to day work bases (Gleason 1998). This is the reason why companies should always think to bring about sanity within their prevalent ranks and hence fully disclose any digital corrections that may take place over the advertisements that they are producing and/or relaying to the general public (Rosi 2010). I would like to end my speech with the belief that the digital corrections on

Essay Example He had to come out a winner in this losing streak. Even if it meant that he would have to take his life. He killed himself. His insurance money will pay his debt and leave some for his wife. The anger and animosity between him and his son, Biff, will cease. As for his job, he will be redeemed and his value to the company will be seen when his clients and co-workers, by the hundreds, will attend his funeral. For Willy, he has finally won. For him, after his death, the tomorrow will be different: for him, his fame will reach greater heights for at his funeral hundreds will come to pay their respects; and, for those he will be leaving behind a more secure future with the money that the insurance company will pay his family. Miller excellently drove his point to the audience that there is no American Dream. Willy’s desire for fame and fortune is seen in the people he epitomizes, Dave Singleman who died a salesman and how hundreds of people came to his funeral (p 81); and, Ben his brother who went into the â€Å"jungle† at 17 years old and came out very rich at the age of 21 (p.52). He wanted desperately to be like them. He always wanted to keep on hearing the stories of these people told over and over and over again (p.49). Miller attacked Willy’s dream in several ways. First, was at work when the son of the owner of the company refused to acknowledge Willy’s importance to the company. He even changed Willy’s work status from a salaried man to a per commission basis one (p.57). Gone was Willy’s fame. Willy’s reaction was one of denial. He instead focused his mind to remembering the past and telling himself that he will eventually be recognized for his 30year service to the company (p.14). Miller used symbolism to depict that Willy despite his denial knew the futility of continuing to work. This symbolism is of the car that keeps â€Å"going off onto the shoulder† of the road. Willy tried

Three Types of People to Fire Immediately Essay Example for Free

Three Types of People to Fire Immediately Essay The article that I read was â€Å"Three Types of People to Fire Immediately† by Michael Maddock and Raphael Louis Viton from Bloomberg’s Businessweek. The authors of this article discuss how we are taught to be creative and innovative from the beginning when we are children. They also talk about how another key element to be successful is to teach managers how to fire people. Maddock and Viton talk about how letting someone go can be beneficial to your organization because some employees are part of the problem and not part of the solution. They say that the people who are innovative and willing to learn are the ones who will push your organization to the next level and that there are three types of people that will hold your organization back. These three people are the victims, the non-believers, and the know-it-alls. The victims are the people who say things like â€Å"Can you believe what they want us to do now? And of course we have no time to do it. I don’t get paid enough for this. The boss is clueless† (Maddock Viton 2011). They will often see problems as singling them out and punishing them rather than a challenge that they need to overcome and persevere. Victims are usually angry, annoyed, and always complaining about anything that they can. They are the ones at the holiday parties that are very negative and don’t really want to be there but come anyway just to bring everyone else down. Maddock and Viton say that victims are not looking for opportunities but instead look for problems because that is the frame of mind that they are used to seeing things in. The authors say that the non-believers think like this â€Å"Why should we work so hard on this? Even if we come up with a good idea, the boss will probably kill it. If she doesn’t, the market will. I’ve seen this a hundred times before† (Maddock Viton 2011). Maddock and Viton believe that the only difference between a winning team that is innovative and the losing one that comes up short can be attributed to the lack of willpower within the corporate culture. Good managers are those who can find the believers in the organization and promote them while weeding out the non-believers to make the organization stronger. The know-it-alls will say things like â€Å"You people obviously don’t understand the business we are in. The regulations will not allow an idea like this, and our stakeholders won’t embrace it. Don’t even get me started on our IT infrastructure’s inability to support it. And then there is the problem of †¦. † (Maddock Viton 2011). Maddock and Viton believe that the best innovators are those who are willing to learn and not those who think that they know enough to get by. It is management’s job to make and sculpt the culture in the way that they want. If management wants to have an innovative culture then they must convey a learning culture because that is the best way to be innovative. It is also said that the know-it-alls become very keen in using their knowledge to constitute why things are not possible rather than trying to find a way to make it possible. The authors say that managers should try to retrain or teach the Know-it-alls before firing them because they can be valuable if they can break their bad habits. In my opinion I would have to agree with this article for the most part. I do believe that it is necessary to get rid of certain employees such as the â€Å"Victims† and the â€Å"Non-believers†. The Victims and the non-believers will only bring your organization down with their negativity and poor attitudes. Not to mention the fact that they are usually incapable of seeing anything as a positive opportunity rather than a punishment or waste of time. There are a lot of things in the world that were seen as a waste of time or a crazy idea to people but because of the believers and dreamers we have a lot of new technology and innovation to this day. The part that I would have to disagree with is when they talk about the â€Å"Know-it-alls† and how they are not innovative. I believe that the know-it-alls can be very innovative and can solve a lot of organizations problems. However, I also believe that they might be more realistic in their thinking and this could be a good thing in that it could help keep the dreamers from getting their heads too far in the clouds. So in my opinion I do believe that it is necessary to fire people for the good of the organization but you should always evaluate what the employee brings to the table and how they negatively affect the organization before action is taken.

Touching Spirit Bear Essay Example for Free

Touching Spirit Bear Essay In the novel Touching Spirit Bear by Ben Mikaelsen he discuses the idea of morals. As the reader reads the novel it is filled with many important lessons from many perspectives. Understanding that all these lessons made Cole a better person. The most important lessons learnt from the book are life is what you make it, forgiveness, and that people can change. The lesson â€Å"life is what you make it† was a big part of the novel. But also this lesson was reflective. When Edwin asked Cole to go to the freezing pond, he gave him a stick and says that the right end of the stick represented happiness while the left end represented anger. Cole broke the anger side of the stick, until he recognized that everytime he broke off the angry side it appeared again. Edwin teaches Cole that anger could not be completely destroyed. â€Å"Yes, was a big deal. It was a party. It was a feast. It was a sharing and a celebration. All because that is what I made it. Yours was simply food because that is all you chose for it to be. All of life is a hot dog. Make of it what you will. I suggest you make your time here on the island a celebration. † (Pg. 166) The hotdog also represented that life is what you make it. Cole made his hotdog just a plain hotdog. While Garvey on the other hand made his hotdog with great care. Garvey’s hotdog was a celebration because that’s is what he intended it to be. Cole made his hotdog just a plain hotdog and it did just that. The sky also symbolizes this lesson. Cole had the decision to look at the clouds or the sun. If Cole had looked at the clouds he would think the weather would be cloudy. If Cole had looked at the sun it would seem as if it was sunny outside. If we were to look at life as a horrible and dreadful place that’s how life is going to be, because that is how we made it. If looking at life as a joyful, beautiful place that’s how life is going to be lived. It will be lived like a celebration! Celebrating every moment of life and living everyday to the fullest. Throughout the novel, Cole is challenged to forgive and to earn forgiveness. Cole had to be willing to forgive himself and those who had hurt him. A lot of forgiving had to be done before Cole could fully heal. First, he was to forgive himself. â€Å"You’ll dance that dance when you’re ready. † (Pg. 184) Garvey said to Cole associating to the dance of anger. For most of the novel Cole was full of so much anger, but by dancing the dance of anger, he let go of some of his emotions and forgiving those who had hurt him. After Cole’s infusion of rage of anger Cole was not as angry as before, he will always know that anger was inside of him but he had the choices to let go and forgive those who had hurt him. He was then ready to move on. Cole could not fully move on without Peter’s forgiveness. Next, Cole needed to help Peter. Cole was truly sorry for what he had done but needed to prove that to Peter and his family. He needed to show Peter that he trusted him, and he wanted to see if Peter could trust him. So before he started his healing, Cole asked to bring Peter to the island to give him a new start. He wanted Peter to get the second chance at life just like Cole had gotten a second chance in the circle justice. This lesson is very important to the book. It teaches that forgiveness is the start to moving on. It shows us that Cole got a second chance by forgiving and receiving forgiveness. Cole experiences extreme anger throughout the novel. He was even known and portrayed as a very angry person. As Cole gets to understand the idea of forgiveness and the beauty of life he changed to become a better and a peaceful person. There are no bad people in the world just people who make bad choices. Cole made several mistakes in his life but has learnt from them and is going through taking dips in the freezing pond, rolling the ancestor rock to get rid of his anger so he would not make the mistakes of anger taking over him again. The Cole first sent to the island was feeling consumed by anger, bitterness, and the feeling to unwillingness to change. While the Cole at the end on the novel is a normal boy that is trying control his anger problems and trying to earn forgiveness from others. After Cole had changed he seemed to think that the island could change anyone. Cole thinks to himself that he has really changed. â€Å"He felt like a new and a different person. † (Pg. 198) That’s why he wanted to bring Peter, the boy who had tried to commit suicide twice after Cole had beaten him up to the island to see if he can change on the island and have another chance at life, like Cole had received. At the end, both Peter and Cole changed spiritually and mentally. The lesson â€Å"People can change† is an important lesson from the book because even Cole the juvenile delinquent had changed into a normal teenage boy controlling his anger. The most important lesson that Cole learnt was that life is what we make it, to forgive and to earn forgiveness, and that anyone can change. Cole always had the options to live life happily but he never knew how to start. But as he learned from the lessons taught to him by many perspectives, he now knows how to start living life without the anger taking over him, he knows how to control his anger. Cole is now more knowledgeable looking at the right end of the stick, centering his life on the sun not the clouds, and making his life a celebration.

Compare Political Systems Of Chile And Argentina Politics Essay

Compare Political Systems Of Chile And Argentina Politics Essay Chile and Argentina are the countries which share their boundaries, have the same official language (Spanish), and they do have the very similar political history. In both countries, they have been under the authoritarian system, and now the democratic systems are very much enforced in their political systems. As they do have very common things, it will be very interesting to have a close look at the difference between these two countries political systems. As many countries are changing to have a democratic society, Chile and Argentina are also trying to use democratic political systems. During the dictatorship regimes in both countries, political situation was very much unstable and as a consequence of political instability, the other systems were very fragile. Throughout the time, these two countries have been changing their political systems as there was not such kind of government that the people willingly supported. However, nowadays, it can be assumed that their political syst ems are strong enough to have the countries function efficiently. In this paper, I will try to compare the political systems of these two countries, much focusing on how the system is based upon on Legislation, Execution, and Judiciary, and political parties in brief. Firstly, I will be discussing the similarity and difference of the legislation system of these two countries. The legislative branch of both countries made up of two houses, Senate and Chamber of Deputies. In the fact that Chamber of Deputies of Argentina represent the people and elected, and it has 275 members which can be variable, and they are proportionally elected from each district, and one term is for four year for the member of the Chamber of Deputies, and have the rights to levy tax, send troop, prosecute the president, state ministers, and Supreme Court ( Gisela, Emilse, Ezequiel, Julio. January, 2006). In Chile, Chamber of Deputies is also directly elected for four year term, and it has 120 members (variable) and Proportionally elected from different regions, and the power of Senate and Chamber of Deputies are very mixed- they have most power as a whole (mongabay, (n.d.)) If we compare the Chamber of Deputies of both countries, we can see that structure of both are very si milar except that in Argentina, the power separation between Senate and Chamber of Deputies is much clear than Chiles. Chiles Senate is also popularly elected as Chamber of Deputies is, and it has 38 seats depending on the population, so it can be variable; in fact, about third-fourth of the Senators are popularly elected and one-fourth is appointed by the Supreme Court. To become Senator in Chile, they have got certain criteria such as the person must be citizen, forty years old, must finish the secondary source, and a resident for three years in the region they represent ( mongabay, (n.d.)) In Argentinas Senate, there are 72 senators, 3 from each district, so the number of the senators is fixed, and popularly elected for a six year term. (nyulawglobal, 2006, January) Therefore, the differences of these two countries Senate were that the number of the Senators in Chile is variable, but it is not in Argentina, and as I have mentioned above, the power separation between Senate and C hamber of Deputies are clear in Argentinas political system- Senate and Chamber of Deputies have each clear task different to Chiles. In Chile, Senate does not have clear separation power as most of the issues they have to handle go through the Congress as a whole. In these two countries, National Constitution is the most influential on the Legislation process. Taxing system, military, foreign affairs and other system which can affect the whole country are especially controlled by written constitution which I will be discussing later in this paper. In the executive branch of both countries, the president is the head of the state and the head of the government, and the cabinet is appointed by the president, and the president is popularly elected for the four year term. It is very interesting that they do have very alike executive system, even the years of term for the president. And, two of these countries are all presidential (executive) dominant countries. In Chile, the presidential initiatives to make the laws just only take around 205 days to complete all the legislation process and for the legislation, it takes around 487 days for the process (Morgenstern Nacif, 2002, p-87) So, it is obvious that president of the Chile can make law much faster than the Congress does, in other words, it mean that president is favored by the constitution. In Argentina also, in recent years, many scholars preferred to classify Argentina as a executive-dominated Delegated Democracy, and Congress lack any real ability to check the president ( Haggard (Ed.), 2001, p-149) Therefore, we can see how the executive branch play a very important role in both countries political process. Many ministries including department of finance are also controlled by the president alone through the cabinet which mainly focuses on day to day process of the countries. In Argentina, the executive branch is still fragile for not able to reduce the corruption among the executive branch only. As Maki wrote in his thesis named Decentralization and Political Participation, tax evasion is rampant, criminal policemen are common, social welfare such as education, health care are under the standard compare to income per capital (Maki, 2006, p-91) These kinds of worse corruption are because of the weak policies of the executive branch and ineffectiveness of the government actions. Though some scholars said that Argentina is one of the democratic countries in Latin America, their executive branch is not unable to monitor those democratic actions. Likewise in Chile, there are many corruptions inside government, but the corruptions are not only in the executive branch but the executive branch and judicial branch together as there is not much power separation between the executive and judicial. the judges take the briberies in pre-trial detention in exchange f or expediting the case, and those judges are much influenced by the executive branch (especially president) through the appointment process ( Transparency International, 2007, p-188) Therefore, in both countries, the executive branch are very fragile from the democratic point of view though the way the corruption happen is different- corruption is directly for the executive branchs fault in Argentina and the executive and judicial are in Chile. After Legislation and Executive, the branch which is the most powerful branch (in power balance) in most democratic countries is Judicial. Whether the judicial branches in Chile and Argentina are most powerful or not will be discussed in this section. Generally, in Chile, judiciary courts are divided into three levels- Supreme Court, Courts of Appeals, and tribunal of first instance. The most powerful level Supreme Court has 21 judges, appointed by the President and ratified by the Senate. It has the power to control all judges from the two inferior levels (nyulawglobal, November, 2005) So, literally, judges from the Supreme Court are the most powerful persons among all judges, but they are balanced by the executive and legislative branches. Argentinas judicial structure is also much similar with Chiles. The only differences are that the members of the Supreme Court of Justice are ministers, and the provinces are much autonomous which means the each province take the responsibility o f correspondence in the Supreme Court. Related to the case of Independence of Supreme Court, according to a survey of Skaar in a paper called Judicial independence and human rights policies in Argentina and Chile, Chile and Argentina have much more independence after the Constitutional reform (Skaar, 2001, pp-11,12) However, as I discussed about the corruptions of Chiles judges above, judges are taking briberies from the people which means that they are not independent anymore. And one more issue is that those judges are appointed by the president. How much independent the judges will be if they are appointed by the executive branches which themselves are corrupted? As Argentina and Chile have politically similar structure (fragile and corrupt), it will be very difficult to say that they have independent Courts. Generally, all Legislation, Executive, and Judicial are interdependent with the constitutions. Based on the constitution, the legislation, executive, and judicial are mainly structured. Written constitutions in Chile and Argentina also have many effects on these three power-balanced sectors. In comparison of the constitution of Chile and Argentina, as they are intended to provide democratic institutions and actions, they have got how citizens are free, guaranteed to basic rights, powers for the legislation and execution and judicial in common. But, Argentinas constitution is much more like a constitution for the federal state because it has very clear separation between the federal government and the province. The federal government provides for the expenditures of the Nation with the funds of the National treasury. Each province shall enact its own constitution under the republican (argentina constitution, n.d.) So, according to the written constitution of Argentina, the federal gov ernment has its own power and conditions and limits what it can do, and the provinces have their own governing power which is guaranteed by the constitution. But, in Chiles constitution the state of Chile is unitary. Its territory is dived into regions. The law shall provide that administration thereof be functional and territorially decentralized. (Constitution of Republic of Chile, 1980, 21st October) It is said that the state is unitary (not federal) and the administration provided by the law should be decentralized in the constitution; however, the constitution doesnt have clear separation how the administration could be decentralized. In the stability of constitution, Chiles constitution is much fragile compared to the Argentina constitution. It could be because Chiles is struggling at the defensive situation- not to have another kind of Pinochet regime. After Pinochet was defeated in 1988, the democratic position organized (centre and left), the political parties which support the military, and the government altogether constituted the social and political institutions that opposed to the Pinochet regime and its 1980 constitution (Montes Vial, 2005, p-13) As they are focusing on preventing of another Pinochet like regime, they lack of ability to control of the stability of the constitution. But, for Argentina, the constitution first drafted in 1853 was improved through the step by step amendments- 1853 constitution and 1860 amendments enforce for the better civil and political rights, and 1957, 1994 amendments had a great emphasis on economic and social rights ( Human Rights and Constitutional Rights, n.d.) So, Argentinas constitution was much concreted with the amendments and led to the stability. The main actors on the legislation, Executive, and Judicial which all are controlled by the national constitution are political parties. The government is also from the political parties, and the congress men are also members of the political parties. In Chile and Argentina, party politics is very common and the ideologies of the political parties shape the countries structure. If we compare the political parties of these two countries, we will see a lot of similar things such as having multiparty system where two main political parties influence. In Chile, Political parties are Christian Democratic Party, The Party for Democracy, the Radical Party, the Socialist Party which of all are center-left, and Independent Democratic Union, the National Renewal (two center-right parties) stand as the main opposites (nationsencyclopedia, n.d.) Though there are a lot of parties, the center-left parties become one coalition and the center right political parties become one side, so basically, we can say that two main sides influence the political process of Chile. For Argentina, there are also many parties such as Justicialist Party, Union Civica Radical, Civic Coalition, the Republican Proposal, but, the Justicialist Party and Union Civica Radical are the two main political parties which are currently getting a lot of support- the Justicialist Party from labor support and the Union Civica Radical from middle-class support (U.S. Department of State, September 16, 2010) Based on these informations, we can see that coalition is common in Chile, and the parties are very much ideology based, but for Argentina, parties stand single and they are based on civil or territory based (not ideology based) which means they are flexible for the people who support them. We will also observe that political parties in Chile and Argentina played a very important role for the democratization process. In Chile, political parties were the main opposition to the military regime (Pinochet regime). Because of those political parties objection on the dictatorship, the motivation for the democratic government emerged in Chile. The political parties officials who are expelled from the office by Pinochet got the valuable opportunity to contact with pobladores. Altogether political parties and those pobladores become the initial opposition for the military regime (Maki, 2006, p-42) Likewise, in Argentina, the political parties became the main groups to have a broad representation in the country. Because of that broad representation of the different levels of people, the democracy was concreted in Argentina. Traditionally, politics was influenced by Landowners, high clergy, merchants, and professionals representing the aristocracy. But in modern times, new parties are emerging to represent working class, small farmers and intellectuals (nationsencyclopedia, n.d.) By representing all different classes, the democracy becomes much meaningful in Argentina. Therefore, political parties are the ones, in one way, who mainly participate democratic movements in both countries, Chile and Argentina. In conclusion, Chile and Argentina has very similar political history, and their current political structures are also very alike. As I have discussed above, they have got the presidential systems and same rules for the presidential election. In the legislation case, Chile is very unitary centered with the provinces administration and the central government is not clearly power separated, and Argentina is much more federal with the separation of power. Although both countries have some kinds of corruption, it can be said that the whole political system of Argentina is much stable than Chiles because Chile is very much focused on preventing another military regime, and for Argentina, it could develop the systems through the amendments for the problematic issues. The political parties in these two countries also played very important role in developing the democratic institutions and actions. Therefore, at last we can say that Chile and Argentina are going forward by amending the weakn ess of the political system, and they are on the way of developing countries which practices the democratic systems.

Self Destructive Behavior and Role of the I function Essay -- Biology

Self Destructive Behavior and Role of the I function The I function describes all behavior associated with the notion of self. Is there really a specific I function and what is its role exactly? Because the I function is linked to the self, one would think that it would prevent harmful behaviors. However, there are cases where the I function does not intervene to terminate detrimental actions for example addiction and a mental disorder called Lesch-Nyhan syndrome. In both cases, a person is harming themselves and can not seem to stop. Does the I function play a role in self-destructive behavior? By researching addiction, more specifically alcoholism, and Lesch-Nyhan syndrome, it is clear that the I function can be overruled by other structures of the brain even when harm to the body is one of the final outcomes. Addiction is defined as a physical and psychological dependence on a substance or behavior (1). Initially the behavior simply satisfies the person but turns into addiction when strong urges accompany the behavior and the person feels that it is needed to avoid painful feelings. What is causing the urges? The brain can be divided into two parts, the primitive brain and the new brain or the neocortex (2). The primitive or beast brain is responsible for survival appetites which are associated with physical pleasure. However, in order to satisfy the urges, the beast brain must communicate to the neocortex and cause the necessary motions to get the drug or exhibit the behavior. According to Rational Recovery (2), the neocortex, or you can overcome the beast brain. Is this alluding to the I function? If this is true, why did the behavior become an addiction in the first place? Where was the I function during that first d... ... the desires of the limbic system, but when necessary the limbic system can ignore the inhibition. There are three structures previously mentioned, the neocortex, the limbic system and the I function. Certainly the first two exist and have specific locations. The I function is only a hypothetical at this point. It fits conveniently into hypotheses. It has not yet been proven wrong but at the same time more evidence is found indicating that the I function can not be included in the same category as structures like the limbic system or the neocortex. It does not have a definite location or a definite purpose. Does the I function exist or is it just wishful thinking that somewhere in the brain is the self or the soul which has some control over our actions whether or not the influence is beneficial.

Physics of Tsunamis Essay -- Tsunamis Weather Essays

Physics of Tsunamis This paper will discuss the physics and warning systems of tsunamis, a destructive wave force that researchers have been studying for many years. Tsunamis are different than tides or surface waves because undersea earthquakes, instead of winds or the gravitational pull of the moon or sun, generate them. They can reach speeds of up to 700 kilometers per hour but can be undetected until they reach shallow water, then unexpectedly arise as deadly waves. Tsunamis evolve from three physical processes, which are generation, propagation, and inundation of dry land. The propagation phase is the most understood, whereas generation and inundation are more difficult to model with computer simulations. Researchers apply a linear wave theory to the propagation phase, which assumes that the small height of the wave compared with the wavelength does not affect the wave’s behavior. Their theory predicts that the deeper the water and longer the wave, the faster the tsunami. Upon inundation, the wave height is so high that the linear wave theory fails to describe the interaction between the water and shoreline. Emergency planners have struggled with getting reliable confirmation of the existence of tsunamis. This has snowballed into a seventy-five percent false alarm rate since the 1950’s. There are plans being put into place to upgrade the warning systems, but the success of improved safety will also depend on the people’s response. The education of coastal communities on evacuation routes and procedures is crucial to improvement of the current tsunami emergency evacuation plans. Physics of Tsunamis To fully understand tsunamis, it will be helpful to first distinguish them from wind generated waves or tides. Ocean breezes can crinkle the surface into relatively short waves that create currents that are restricted to a shallow layer. Strong winds are able to whip up waves that are 30 meters or higher but even these do not move deep water as the tsunamis do. Tides, which sweep around the globe twice a day, also do not produce currents that reach the ocean bottom. Unlike true tidal waves, however, tsunamis are not generated by the gravitational pull of the moon or sun. A tsunami is produced by an undersea earthquake, or much less frequently, volcanic eruptions, meteorite impacts, or underwater landslides. Even though tsunamis can reach speed... ... better evacuation routes. With the combination of technology and community awareness, coastal residents will have a much better chance at avoiding the destructive forces of these killer waves. Conclusion Tsunamis have been a major threat to coastal areas for many years. The challenge in the past has been early detection; due to the way they speed towards the coastline hidden in deep waters, only to surface close to the shore as a powerful, destructive wave. However, with recent advances in technology and a better understanding of nature’s ways, we may be able to protect property and people by educating them on these powerful waves. People in the tsunami’s path must use the current warning system improvements in conjunction with a timely response to avoid future catastrophes. Community education programs would seem to be a good starting point. If researchers, emergency planners, and community leaders will work together in a team effort, I believe the death toll and property damage will be kept to minimal figures.
