Overload and Reversibility Essay Example

Overload and Reversibility Paper We train to improve our physical abilities, but this can only be achieved by a change in everyday activity. Every type of training that takes place has a principle behind it. These principles are Specificity, Progression, Overload and Reversibility.  Specificity Training must be specific to the activity or sport that you are training for. There is no point going swimming everyday if youre a basketball player. You may wish to work on one particular area, such as building muscles in legs and arms (E.g. Football, Rugby). Specific training will produce specific results, so it is important to remember two things. 1) Individuals will respond different.  2) Each activity will have different demands.  Overload This is making work harder to improve performance. The workload must be extended to improve at a faster pace. This can be achieved in the following ways:  Frequency of training. Start once a week and progress to two times a week etc  Intensity of training. Increase heart rate to a higher level, to increase stamina.  Duration of training. To increase the length of the training session. Progression The training that you are doing must be increased progressively. As your body adjusts to the demands you are putting on your body, you must increase the workload steadily. Do not do too much too soon.  Reversibility Just as progression can lead to an improvement, if you either stop or decrease the training, you reverse and lose the effect. All the hard work you have done will be lost.  I designed the circuit to work mostly on the legs, to increase speed and precision. This can be seen on the design of my circuit.

I chose this as my first station because it is fairly easy to do, and it helps to get the muscles warm. Squat thrusts work on the [GET PART OF BODY THAT IT WORKS ON] muscles, and help to boost the power in the legs. I carried this out by positioning my body as if I was going to do a press-up. Shoot in legs to the elbows and then back to the starting position. Correct technique needs to be used in this exercise, because serious damage can occur to the lower back and legs. Shooting is at station two. This station works on the accuracy of the legs, and helps with acquiring the proper shooting technique. I did this exercise by standing behind the ball, placing my left foot parallel to the ball with my toes pointing towards the target, and kicking the ball with my right foot at my specific target.  After station two is station three with sit-ups. This works on the abdominal area to help with developing a six-pack. This is one of the favourites exercises amongst male teenagers, because it is used to woo and impress female teens. Sit-ups are done with a partner, in a sitting position, hands just behind ears. Legs at right angles, lie back and then curl towards knees while partner holds legs down. At station four there is the passing exercise. This exercise helps ones abilities to perform accurate passes when playing football. The technique for passing is the same for shooting, except more care needs to be taken when passing to a teammate. You have to put yourself in the shoes of your teammate and pass it how you would like someone to pass it to you. There is no point in kicking the ball as hard as possible if you are passing to your teammate who is right next to you. He might not be able to control it. After the passing is the shuttle run at station five. This helps the legs to perform at an increased pace to increase speed, which will in turn be very useful if you need to retrieve a loose ball in a football match. This exercise is done by standing sideways on to the start line, knees slightly bent. Run to the line at the other end of the station, bend down and touch with right hand and then run back to first line and repeat. There is the ladder test at station six. This, amongst all the other stations work on the legs, but this exercise has a somewhat advantage over the rest. It is a mix between using speed and precision to successfully complete it. The aim is to run as fast as possible through the ladder without hitting the ropes. One must try their best to refrain from getting tangled with the ropes. If that happens, he/she could fall and the injuries could be fatal.  All footballers must be able to dribble the football. Station seven is specific to this technique. To complete this exercise, one must be very agile and very precise with the legs. This exercise is done by manoeuvring the ball through the cones, trying desperately not to hit them. The last station on my circuit is the sprint running. This helps the legs to perform at a faster pace and helps footballers to have much more stamina. It is also highly used in small areas because there is no movement. This exercise is done by running on the spot, but with sprinting with high knee lift and fast arm action.  I was motivated by my friends to do this circuit, because they all thought that I was falling behind in my football skills. I asked a friend to help me with completing the sit-up exercise, because I needed a partner to hold my legs down. I felt very good with myself, knowing that my fitness levels were increasing. I did this programme once a day for eight weeks. I spent one minute on each station, and 20 seconds of rest between them and I started to notice changes in my physical appearance after my fourth day. My calves were beginning to get bigger and my hamstrings also begun to get bigger.  To warm up, I did two laps around the circuit to warm up my muscles. After successfully completing my warm up, I started with my stretches [TALK ABOUT THE DIFFERENT TYPES OF STRETCHES THAT I DID]. And to warm down, I simply walked with my hands behind my head for approximately five minutes to increase the capacity of my chest, which make more oxygen available to me to breathe in.

mail vs femail communication styles essays

mail vs femail communication styles essays You say the glass is half-empty; I say the glass is half full. This is the way people communicate daily on a personal level or professional level. Effective communication however, is the ultimate key. As we know, communication is carried on all over the world, in many different languages, slangs, and dialects that have developed over time through the communication process. Perhaps the most obvious difference in achieving effective communication is seen in any culture, or race between males and females. Though not as obvious or radical as two different languages, it is a difference that can be equated to such. Males and females have definite different communication styles, and as a result, we respond differently under various professional, social, and personal situations. Like the book title implies, "Men are from Mars, Women are from Venus" we are very different. We are not from different planets, but why does it seem that way? We are raised under different norms. Is it wrong that we raise our boys and girls differently? That is a question that stems back many years and cannot be answered in this paper. Historic traditions instilled inside all of us that are unconsciously passed down through generation after generation, makes us the people that we are. The key word is UNCONSCIOUSLY. It is part of our culture to treat the sexes differently. In most cultures women have been raised to be more passive than men, and this trait usually sticks with them all through life. From grade school on up, women have been the quiet ones. In school, guys were the ones being loud and obnoxious (remember throwing rocks and dirt at the girls.) Little did they know, that was the male way of saying "I am here, notice me", or "I really like you." Girls would respond with a smile to the guys or say "he is so stupid" to her friends. They use this as a shield for their real feelings and a w ...

Energy Assignment Example | Topics and Well Written Essays - 1000 words - 1

Energy - Assignment Example 1. Electrical energy: I use electrical energy originating from the state’s power house and travelling through power lines to reach my machines. The energy is renewable as the power plants are hydro-electric. In my chosen location, Sumter South Carolina, the most appropriate renewable source of energy is electrical energy. This is because the power house of South Carolina uses water to generate electricity. Water is ample here as there is good water management in this state. Rainwater also accumulates in dams which becomes a good source of electricity. Some people have also implemented solar panels but that is not a good idea as the changing season does not provide ample solar energy all the year. The two inappropriate sources of energy in this location include chemical energy and radiant energy. Chemical energy becomes inappropriate when people burn coal and other fossils for fire and other purposes. This causes pollution, thus making the environment not so green. An alternative is to use heat energy from gas heaters since South Carolina has a number of natural gas providers. Radiant energy, which originates from electromagnetic waves, is inappropriate when people use it to cook or warm food through unnatural means, such as the microwave. People are using microwaves more and more often to cook food, which makes it harmful when the radiant energy of the microwave comes into contact with the food particles over a prolonged period of time. Electrical energy is a safer alternative allowing local people to cook food on stoves. The advent of technology has greatly facilitated the implementation of renewable energy resources. Stapleton (2010, p.178) states that since there are billions of people who do not have access to clean water, sanitation, and modern services that produce affordable energy, the need for renewable energy (RE) technologies will be on its rise in the coming years to cater to the

Alternative Pain Therapy - Research Proposal Example Dishonest conduct comprises manipulation of design and methods, and manipulation or retention of data. The research will avoid all forms of dishonesty by truthfully recording the facts obtained from the primary, secondary and tertiary sources. Problem Background and Significance â€Å"Wars have always brought about significant improvements in medicine that also affect the civilian population†.4 Some early methods of cure are now being included to the treatments and prescriptions that are being used now. The armed forces apply acupuncture as a pain management therapy in the United States as well as in Germany. The objective is to offer a complete, holistic way to pain therapy for armed forces recruits. Acupuncturists are being appointed to practice together with a group of doctors and psychotherapists. Acupuncture is part of conventional Chinese medication. Acupuncture practitioners stimulate particular points on the body - mainly by â€Å"inserting thin needles through the sk in†5, which normalizes the flow of ‘vital energy’ along pathways called â€Å"meridians†.6 This method appears to be safe and effective for chronic orthopedic pain. Recent studies have found that acupuncture offers pain relief and enhances mobility for individuals with osteoarthritis of the knee. There are smaller number side effects linked with acupuncture than with various regular medications (for instance, anti-inflammatory drugs and steroid injections) for curing painful musculoskeletal.7 Another such alternative pain therapy, adopted by armed forces is transcutaneous electrical nerve stimulation (TENS). Although it does have few side effects but it is extremely useful for curing chronic orthopedic pain. Taking into consideration the increase in amputations, nerve injury and other... The author of the essay assumes that soldiers utilize these drugs to deal with pain due to injury during the combat as well as to handle the emotional suffering of war fatigue or being compelled to observe wartime killings. A comprehensive study revealed a major setback with overmedication of soldiers pulling through combat wound. Overmedication can take the shape of various drugs that cause excessive doses. The Army is taking steps to rectify the situation by utilizing an automated patient record. This research will explicate in details the possible alternatives that military soldiers suffering from pain should use in order to have a wide range of choices in their pain management. This information will be beneficial since they will know how to handle themselves better in a safe and cost effective way. Scientific honesty is also regarded as an extremely essential ethical responsibility when conducting research. Dishonest conduct comprises manipulation of design and methods, and manipulation or retention of data. The research will avoid all forms of dishonesty by truthfully recording the facts obtained from the primary, secondary and tertiary sources. Alternative therapies have been used for curing pain in the field of war from around last ten years, and will now be â€Å"extended to post-acute care†.1 The military’s plan in using these therapies as an integrative pain management may initiate its use in additional civilian hospitals because they are safe as compared to taking high dosage of drugs, and are more cost-effective.

The Dental Induced Bacteraemia

The Dental Induced Bacteraemia Your Uncle not the same as last time who has been taking clopidogrel for a number of years approaches you, a dental student, to explain something to him. After two weeks of weariness and fever, his doctor recently diagnosed Infective Endocarditus by blood cultures. An echocardiogram indicated a bicuspid aortic valve, and listening to the chest using a stethoscope the doctor could also detect a slight murmur. His doctor had asked him whether he had had any dental treatment recently. He admitted that he had not seen a dentist for a number of years and a cursory investigation revealed dental caries and inflammation of the gums. His reason for avoiding the dentist was because of bleeding in the mouth following visits. Your Uncle was quizzical about a number of things and has asked for your advice. He wants to know what information the echocardiogram and stethoscope can reveal. Further, he wants to understand the connection between oral health and an individuals general medical condition. Specifically, what oral bacteria are present, what roles do they play in oral biology, how they could cause systemic problems, and what sort of strategies could be employed to prevent infection. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦. Working in your groups, generate a list of leaning outcomes for this topic and return an individual copy by 23rd November by email to [emailprotected] These learning outcomes will be assessed, and intended learning outcomes returned to assist you with your report. Individually write a 2000 word manuscript in a scientific manner addressing the learning outcomes by 7th January (2013) and upload via QMplus. Please note that with QMplus the time cut-off is 23:55. Learning Outcomes 1. To identify the connection between clopidogrel and excessive bleeding gums. 2. To describe normal and abnormal heart valve formations. 3. To understand and describe the information that echocardiograms and stethoscope can provide regarding heart function. 4. To explain how oral derived bacterial flora can colonise heart valves. 5. To explain why the heart valves are susceptible to bacterial colonisation. 6. To describe when prophylactic antibiotics should be prescribed prior to oral treatments. Introduction Bacteraemia is a condition that is caused when bacteria enters the blood stream. When large amount of bacteria are present in the blood it can cause infections such as meningitis, pericarditis and endocarditus. Individuals with heart valve disorders, prosthetic joints, chronic diseases or weakened immune system are at increased risk of developing infections during Bacteraemia. Dental induced Bacteraemia is caused by minor injury from tooth brushing or from dental procedures. In the above problem based learning scenario we have been presented with our uncle who has been taking Clopidogrel for a number of years and has now been diagnosed with Infective Endocarditis by blood cultures. Below I will expand on the proposed learning outcomes. [2] FIG.1Identify the connection between Clopidogrel and excessive bleeding gums. Clopidogrel is an oral antiplatelet drug which reduces the risk of blood clots forming. It works by preventing Adenosine diphosphate (ADP), which causes platelets aggregation, from binding to its P2Y12 receptors on platelets and stops activation of the glycoprotein GPIIb/IIIa complex. This prevention reduces the likelihood of clots forming. [1] [3]Source:Harvey, R; Champe, P Lippincott illustrated reviews: Pharmacology, 4th edition. LWW: 2009. Blood clots can be very dangerous as they can cause blockages of blood vessels reducing the blood supply to an organ. A reduction in blood flow to the brain or heart can cause a stroke or heart attack. This explains Clopidogrels biggest use in patients who have had a recent heart attack or stroke; it helps to stop a reoccurrence. [1] Taking Clopidogrel therefore can cause excessive bleeding gums. If a blood vessel ruptures when brushing the teeth, through dental treatment or even by eating the gums will carry on bleeding for longer than usual because of the lack of platelet aggregation. http://birthnow.com/wp-content/uploads/2012/05/Clopidogrel.gif Describe normal and abnormal heart valve formations. A healthy human heart consists of four chambers; two upper atria and two lower ventricles and four valves; two semilunar and two atrioventricular valves. The aortic and pulmonic valves are both semilunar valves and found in the arteries leaving the heart. The tricuspid and mitral valves are the atrioventricular valves and are found between the atria and ventricles. [5] Valves are made up of cusps which basically act as flaps or leaflets that are responsible for the one way flow of blood going into and out of a ventricle. Each valve has three leaflets, except the mitral valve, which only has two. [4] FIG.3Strong fibrous cords called chordae tendineae also known as heart strings are attached to the papillary muscles found on the floor of the ventricles and they act as anchors to stop the valves from inverting back into the atria. When the valve closes the papillary muscles contract and tenses the chordae tendineae to ensure the one way flow of blood. The valves are also supported and surrounded by a fibrous skeleton called annuli that also acts as another anchor. http://www.tokresource.org/tok_classes/biobiobio/biomenu/transport_system/heart-valves.jpg [6] FIG.4Blood flows from the right and left atria into the ventricles through the open tricuspid and mitral valves respectively. When the ventricles are full, the tricuspid and mitral valves shut. The ventricles now begin to contract and the pulmonic and aortic valves are forced open and blood is pumped out. Blood from the right ventricle passes through the open pulmonic valve into the pulmonary artery and carries deoxygenated blood to the lungs while blood from the left ventricle is oxygenated and travels through the open aortic valve into the aorta and goes to the rest of the body. This happens in a cycle, between heartbeats the ventricles will then relax, the semilunar valves will close and the atrioventricular valves will open and allow blood from the body and lungs to enter the heart. [7]http://mitral-valve-repair.com/wp-content/uploads/2011/01/heart-valves_heart-chambers.jpg Heart valves can however malfunction in several ways. Abnormal heart valve formations fall into two main groups; Regurgitation and Stenosis. Regurgitation of the valves is when they fail to close properly which causes the backward leakage of blood, this is often happens as a result of coronary heart disease, rheumatic heart disease or because or bacterial and viral infections including infective endocarditus. [8] Mitral regurgitation is the most common heart valve disorder being found in 20% of adults over the age of 55. [9] The backward leakage of blood causes an increase in atrial pressure and the wall of the left atrium will thicken by hypertrophy and possibly dilate. The pulmonary venous pressure will also rise which produces pulmonary oedema (fluid accumulation in the air spaces).It also reduces the blood supply to the rest of the so the left ventricle will also become thicker and the heart rate will increase to try and maintain normal cardiac output. Symptoms include shortness of breath, chest pains, dizziness and the pulse becomes faster. [10] [11] Stenosis of the heart valves occurs when the valve is narrowed and obstructs the forward flow of blood, it is usually a result of a congenital defect which has caused the valve to become inflamed or calcified. [12] FIG.5 Aortic Stenosis Aortic valve Stenosis is one of the most common valve disorders, when the valve doesnt open correctly there is reduced blood flow from the left ventricle into the aorta. In severe cases the walls of the left ventricle will become thicker as it has to work harder to maintain cardiac output into the aorta. Symptoms include dizziness, chest pain and an irregular heart beat. If the condition worsens it can lead to heart failure and more uncommonly to endocarditus.http://www.heart-valve-surgery.com/Images/aortic-stenosispicture-275.jpg Aortic Stenosis develops over time because or turbulent blood flow through a usually bicuspid aortic valve. Calcific valvular disease is an inflammatory process and the biggest cause of the disorder, calcification of the valve makes it very stiff and makes it difficult for the valve to open easily. Again as with regurgitation rheumatic fever and endocarditis are also causes of Stenosis. [11] [12] Valve deformations are more common in the left side of the heart but they do also occur in the right hand side. Stenosis and regurgitation can affect all four valves and not only the two mentioned above. [13] Other abnormal valve formations are congenital heart valve diseases which are those present at birth when the aortic or pulmonary valves dont form properly. Understand and describe the information that echocardiograms and stethoscope can provide regarding heart function. Echocardiography is a non-invasive technique used to assess cardiac structure and function by the use of ultrasound. Echoes are used to listen for congestion in the lungs, irregular heartbeats and murmurs. [11] There are several types of echocardiograms; transthoracic (TTE) are the most common. A device called a probe or transducer is placed on the chest and high frequency sound waves are used to produce sounds and images of the heart. It picks up echoes of sound waves and transmits them as electrical impulses which are then converted to 2D or 3D moving pictures on the screen. A Doppler echocardiogram shows the movement of blood. If a clear picture cannot be formed a small amount of liquid can be injected via IV to give a better picture. [14] Echocardiograms show details of the chambers including size, volume and thickness of the walls which helps to identify certain disorders including hypertension, the pumping function can also be reviewed and this can show conditions such as cardiomyopathy. Echoes also help with diagnosis of heart valve disorders including those mentioned above. It identifies the basic structures of the valve including thickness and movement and shows any abnormalities such as calcification and scaring. The Doppler will show any leakage through the heart valves and if there is a restriction in blood flow. Echoes of mitral regurgitation will show a dilated left atrium and left ventricle and echoes of aortic Stenosis will show the thickened calcified leaflets. In cases of suspected endocarditis a transesophageal echo can be used instead to show high-quality images of the heart and its valves. It is slightly more invasive and a long tube is passed down the oesophagus. [15] A stethoscope is a non invasive diagnostic instrument used to listen to or auscultate a patients heart, lungs, pulse and abdomen. It can also be used to help check blood pressure by listening to blood flow restoration when the sphygmomanometer cuff is removed. The diaphragm is placed on the patients chest where it picks up vibrations and amplifies them as sounds to the earpieces going via a hollow tube. [16]http://upload.wikimedia.org/wikipedia/commons/3/3c/Stethoscope_(PSF).png A healthy heart produces a double beat or lub dub with little other sound when the semi lunar valves open and close. A stethoscope helps detect a heart murmur which makes a whooshing sound after the heart beat, this can indicate serious other problems such as infective endocarditis. [17] [18] FIG.6 S Mutans adhering to surface of mitral valve Explain how oral derived bacterial flora can colonise heart valves Explain why the heart valves are susceptible to bacterial colonisation. Streptococcus mutans are a type of bacteria found in dental plaque of the oral cavity that is largely responsible for causing tooth decay and cavities via the process of demineralisation. However on occasion after dental treatment or from brushing the teeth if blood is exposed it can enter the blood stream and cause bacteraemia. Diseased Aortic Valve Endocarditis typically develops on surfaces of the heart, which have become rough and sticky after sustaining endothelial damage after being subject to turbulent blood flow. (In bicuspid valves blood flow is more turbulent and this creates a high pressure which makes the surface of the valve rough and more susceptible to bacterial colonisation). [19] Platelets and fibrin attach to the endochardium surface and form a platform which the bacteria can attach to; vegetation is now formed. This vegetation can damage the heart valves and affect how they open and close, or breakaway and cause complications in other areas of the body. The aortic and mitral valves of the left side of the heart are the most common to be affected. S mutants are thought to be responsible for 50% of all bacterial endocarditus cases. Staphylococci found on the skin can also cause it. [11] The risk of developing endocarditis is increased in a person who has already got artificial heart valves, general heart valve conditions, congenital birth defects, rheumatic fever and those with a lowered immune system. The problem with when bacteria colonises heart valves is that the valves dont have a designated blood supply to them so white blood cells are unable to fight the infection that is forming there. [20] [21]Full-size image (41 K) [22] FIG.7 Transthoracic echocardiogram (a) and apical four-chamber view (b) demonstrating a well circumscribed vegetation measuring 2 ÃÆ'- 1 cm, confined to the posterior mitral valve leaflet and impinging on the left atrium. Describe when prophylactic antibiotics should be prescribed prior to oral treatments. The term prophylactic antibiotics refer to when antibiotics are given prior to an event as a preventative measure to infection. Where rheumatic fever is still common, control and prevention will prevent rheumatic heart disease and associated endocarditis. [11]Previously people with heart valve conditions and artificial valves were thought to be at high risk of developing endocarditus when receiving dental treatment and other surgical operations so a treatment of antibiotics, usually penicillin were given prior to the procedure in question. Today however this practice is questioned as there were no placebo trials conducted. The large scale use of penicillin as a preventative measure comes with risks such as anaphylactic shock so now as recommended by the National Institute for Health and Clinical Excellence (NICE) it is mainly only offered to those patients who have an infection beforehand and those with artificial valves. Conclusion In conclusion to this PBL I now understand that the presence of bacteria in the blood can have serious consequences all over the body and not just at the site of entry. In answer to my uncles question about preventing infection it would be worth noting that meticulous oral and skin hygiene is significant in preventing such infections like endocarditis. With regards to oral hygiene a dentist should be seen at least every 6 months so any issues that may be present can be resolved before they develop further. Brushing twice a day, flossing and keeping ones toothbrush clean are always that can prevent bacteraemia.

How important are the chapters one to three in Great Expectations? Essa

How important are the chapters one too three in Great Expectations? What does the reader learn about the social and historical, from these chapters? The setting from the start of the book is very important, from the unwelcoming and stereotypical graveyard that give the book a starting tense and exiting mood, and the humble blacksmiths that acts as a platform for Pip's expectations and the opposite setting to much of the grander scenery in London. The graveyard at the start of the book is typical example of how the setting contributes so well to the story and the atmosphere; this is just one of the more obvious examples. Starting the book in a graveyard quickly informs the reader of a lot of information about Pips history that under different circumstances would have taken a lot longer to explain; things like Pips parents and family were quickly and briefly explained to the readers via the gravestones and Magwitches asking "Where's your mother?" and Pip's response being "There sir" as he points to his Mother, Father and five sibling's gravestones. The graveyard is...

Han’s Crime

Hand's wife gave birth to a baby eight months after their marriage. Han was under the Impression that the baby belonged to his wife's cousin. Han told everyone that It was a premature birth. This explained why the baby died so soon; nevertheless, It was actually the wife who killed the baby by smothering It with her breasts. For the rest of Mr.. And Mrs.. Hand's marriage, Han did not approach his wife and ask her if the baby was his. It seems to me that Han does not face his problems, but runs away from them or take the easy way out. For example, Han did not want to ivories his wife because he did not want there to be any wrong on him.If Han had confronted her about the possible affair as well as the death of their baby, their marriage would have gone in a completely different direction that did not end in one of them killing the other. I do not mean to say that they would have lived happily ever after or anything, but it definitely would have helped their relationship with each othe r. The birth and death of the baby symbolizes a new beginning for Han. â€Å"The child's death seemed Like retribution for everything and I decided that I should be as ignoramus as possible†.Han replaced the love for his wife with a tremendous hatred towards her. He thought of divorcing her, but having recently converted to Christianity he did not want there to be any wrong by his doing. Hand's actions cause me to think of him as the kind of person who works hard to please everybody. I mean, his Job is to entertain people. Becoming a Christian definitely made him an even greater person in his audience's eyes. When he was in the courtroom he told the judge that he did not know if he was guilty or not, he decided to tell the truth.I decided that the best way of being acquitted would be to make a clean breast of everything†, â€Å"Why not be completely honest†. That that is the kind of thing someone who wants to please people would say in his situation. In my opinio n Han did not mean to kill his wife; on the contrary, subconsciously he did kill her on purpose. Han would never hit his wife. Yes he was harsh, but never did he physically harm her. Of course that was Just because his conscious told him that that was wrong. Deep down Han wanted to hurt her and rid of her. Even though the

Kinetic Molecular Theory of Gases

Kinetic Molecular Theory of Gases The kinetic theory of gases is a scientific model that explains the physical behavior of a gas as the motion of the molecular particles that compose the gas. In this model, the submicroscopic particles (atoms or molecules) that make up the gas are continually moving around in random motion, constantly colliding not only with each other but also with the sides of any container that the gas is within. It is this motion that results in physical properties of the gas such as heat and pressure. The kinetic theory of gases is also called just the kinetic theory, or the kinetic model,  or the kinetic-molecular model. It can also in many ways be applied to fluids as well as gas. (The example of Brownian motion, discussed below, applies the kinetic theory to fluids.) History of the Kinetic Theory The Greek philosopher Lucretius was a proponent of an early form of atomism, though this was largely discarded for several centuries in favor of a physical model of gases built upon the non-atomic work of Aristotle. Without a theory of matter as tiny particles, the kinetic theory did not get developed within this Aristotlean framework. The work of Daniel Bernoulli presented the kinetic theory to a European audience, with his 1738 publication of Hydrodynamica. At the time, even principles like the conservation of energy had not been established, and so a lot of his approaches were not widely adopted. Over the next century, the kinetic theory became more widely adopted among scientists, as part of a growing trend toward scientists adopting the modern view of matter as composed of atoms. One of the lynchpins in experimentally confirming the kinetic theory, and atomism is general, was related to Brownian motion. This is the motion of a tiny particle suspended in a liquid, which under a microscope appears to randomly jerk about. In an acclaimed 1905 paper, Albert Einstein explained Brownian motion in terms of random collisions with the particles that composed the liquid. This paper was the result of Einsteins doctoral thesis work, where he created a diffusion formula by applying statistical methods to the problem. A similar result was independently performed by the Polish physicist Marian Smoluchowski, who published his work in 1906. Together, these applications of kinetic theory went a long way to support the idea that liquids and gases (and, likely, also solids) are composed of tiny particles. Assumptions of the Kinetic Molecular Theory The kinetic theory involves a number of assumptions that focus on being able to talk about an ideal gas. Molecules are treated as point particles. Specifically, one implication of this is that their size is extremely small in comparison to the average distance between particles.The number of molecules (N) is very large, to the extent that tracking individual particle behaviors is not possible. Instead, statistical methods are applied to analyze the behavior of the system as a whole.Each molecule is treated as identical to any other molecule. They are interchangeable in terms of their various properties. This again helps support the idea that individual particles dont need to be kept track of, and that the statistical methods of the theory are sufficient to arrive at conclusions and predictions.Molecules are in constant, random motion. They obey Newtons laws of motion.Collisions between the particles, and between the particles and walls of a container for the gas, are perfectly elastic collisions.Walls of containers of gases are treated as perfectly rigid, do not move, and are infinitely massive (in comparison to the particles). The result of these assumptions is that you have a gas within a container that moves around randomly within the container. When particles of the gas collide with the side of the container, they bounce off the side of the container in a perfectly elastic collision, which means that if they strike at a 30-degree angle, theyll bounce off at a 30-degree angle. The component of their velocity perpendicular to the side of the container changes direction but retains the same magnitude. The Ideal Gas Law The kinetic theory of gases is significant, in that the set of assumptions above lead us to derive the ideal gas law, or ideal gas equation, that relates the pressure (p), volume (V), and temperature (T), in terms of the Boltzmann constant (k) and the number of molecules (N). The resulting ideal gas equation is: pV NkT

Role of Women in WWII essays

Role of Women in WWII essays When I previously thought about the participants of World War I, I imagined brave, young men fighting fearlessly for the country they believed in. I envisioned the war fields dotted with machinery, trenches and fortresses that helped to protect the heroic men who fought continuously until the end. I pictured the victorious soldiers returning home to accepting and joyous companions whom they had been away from for so long. Not once did I think of the women volunteering for the war. I figured they simply sat at home praying for the safe return of their loved men. However, in closer examination of The Great War, I have learned of my naivety. In reality, women were as much a part of the war as were men. Although women played distinctly different roles, their experiences were often virtually indistinguishable to those of their male comrades. For example, women and men had the same pressure put upon them to volunteer for the war. Once involved in the war, both genders were forced to question their previous beliefs and their learned virtues while discovering that this great war wasnt what had been expected. Men and women had to suffer from extremely horrible living conditions, face the fact that they were simply a number to the country they were fighting so valiantly for and learn to psychologically deal with experiences nobody had ever fathomed before. And when those who were lucky enough to survive returned home, they had to reevaluate their relationships with those they had left behind, often times discovering that the only thing that war had provided was an uncertain future. I often wonder if as many men and women would have volunteered for the war if they had known what they were up against beforehand. Deductive reasoning tends to tell us they would have been more reluctant, but the pressures from their countries were so intense that many may not have had much of a choice but to enlist. Volunteers entere...

Journey of Slavery - Essay Example America was discovered by Spanish explorer, Columbus in the 16th century, who had developed good relations with the native Indian population. But the early 17th century saw the process of colonization by the British settlers who had brought shipload of African slaves as bonded labors to work on plantation and elsewhere. They also tried to exploit the native Americans with respect to labor and sea faring activities The indentured labor consisting of European workers, worked as bonded laborers who were freed after several years so as to payoff their passage to a new country. The slaves worked in labor intensive tobacco plantations along with Native Americans who later refused to work because they were afflicted with diseased like tuberculosis etc. which were brought by the settlers. The slave trading was started by the Portuguese in 1572 when they had gone to west Coast of Africa where the tribal wars resulted in captives Africans who were traded as slaves in the European market (Liu). The African tribes were skilled farmers who were also known for their intricate art work on metal and wood. Thus the Europeans were able to exploit their skill by buying them and using their skilled labor for free. The slaves were denied basic human dignity of good living condition and food. When new world was discovered, the slaves were transported to the new world by the whites. In the eighteenth and nineteenth century in America, the color of the skin played a major role in the social status. The whites maintained a racial divide within the society through deliberate use of powerful lobby of the whites and financial advantages that they enjoyed over their less privileged counterparts, the Native Americans. The blacks were not allowed to participate in social activities and even education was denied to them so that they would remain unequal socially and economically. Turn of the century saw the raced based
