...Internal Assessment The Effect of External Temperature on Muscle Fatigue Henry Richardson Biology HL Mr. Lee September 24, 2016 IB Candidate Number: 004622-0032 Word Count: Design Research Question: What is the effect of external temperature on muscle fatigue? Introduction: Muscular fatigue is caused by various things, one of which being insufficient adenosine ti-phosphate or ATP for short. ATP is an energy source that is essential to muscular contractions. Its production is primarily aerobic, however when there is insufficient oxygen for aerobic synthesis to occur, it will happen anaerobically which produces lactic acid as a by product ("Sports 'n Science”). ATP has an essential role in the contractions and fatigue...

...Objective: To demonstrate and explain muscle fatigue Variable Choices: Temperature (hot,neutral and cold) Background Information: The bones on the skeleton are caused to move by skeletal muscles. When muscles tend to contract it creates the ability of the joints to move and let us engage in physical activities. For muscles to contract, chemical energy is required. The chemical energy is a result of respiration. The skeletal muscle is made of two different kinds of fibers: slow twitch (ST) and fast twitch (FT). Slow twitch fibers are mostly used in prolonged, because they are low and moderate the intensity activities. Slow Twitch fibers are more efficient at using oxygen to extend muscle contractions over a long time. As for the fast twitch fibers they use up more energy and the muscle fibers contract very fast. They are much better at generating short bursts of strengths and that slow. The fast twitch are usually used in short intense activities....

...Results and Discussion The main objective of the study was to assess if the symptoms of Chronic Fatigue Syndrome are present in men and women aged 45-50 years, working in the private sector. The hypothesis was that there is a significant difference in the fatigue experienced by working men and working women. Results showed the t value higher than the critical value, indicating a significant difference in the scores of working men and women and therefore the hypothesis was accepted. CFS is most common among people in their 40s and 50s. Gender also plays an important role in CFS, as women are at least twice as likely to develop CFS as men. The thesis is centred on the fact that women are more prone to CFS than men. While scoring the checklist,...

...located in the front lower part of your neck. Hormones released by the gland travel through your bloodstream and affect nearly every part of your body, from your heart and brain, to your muscles and skin. The thyroid controls how your body's cells use energy from food, a process called metabolism. Among other things, your metabolism affects your body’s temperature, your heartbeat, and how well you burn calories. If you don't have enough thyroid hormone, your body processes slow down. That means your body makes less energy, and your metabolism becomes really slow. The most common cause of hypothyroidism is thyroiditis. Thyroiditis is an irritation of the thyroid gland. Thyroiditis is an autoimmune disorder. With this, your body produces antibodies that attack and destroy the thyroid gland. Thyroiditis may also be caused by a viral infection. There are also many other causes of hypothyroidism. Women, particularly older women, are more likely to develop hypothyroidism than men. You are also more likely to develop hypothyroidism if you have a close family member with an autoimmune disease. Babies with hypothyroidism may have no symptoms. If symptoms do occur, they can include: * Cold hands and feet * Constipation * Extreme sleepiness * Hoarse cry * Little or no growth * Low muscle tone (floppy infant) * Persistent jaundice (yellowing of the skin and whites of the eyes) * Poor feeding habits * Puffy face * Stomach bloating * Swollen tongue ...

...Combating Compassion Fatigue Kadijatu Lewis Grand Canyon University: HLT.310V April 14th, 2013 Nursing is an emotional, physical spiritual and hard work. It is also rewarding and most times satisfying. Nurses witness pain and suffering of others daily, resulting in increase risk for emotional stress. Nurses also work under demanding conditions related to budget constraints, and short staff resulting in increase workload. Compassion fatigue is the last stage of compassion discomfort and compassion stress. The nursing profession does not provide adequate resources to help combat this condition, like other professionals who deal with similar situations. This paper will identify signs and symptoms of compassion fatigue and ways of combating them. Compassionate fatigue is an emotional, physical and spiritual exhaustion from witnessing and absorbing the problems and suffering of others. Compassionate fatigue usually affect selfless, caring and sacrificing nurses who are emotional attached to their jobs. It usually comes on gradually. It usually occurs when a caregiver attempts to give out more compassion and energy than they are getting in return. When we exhibit compassion fatigue, our natural human desire to help is significantly diminished (Frandsen, 2010) Compassion fatigue manifest itself in different ways, these include feeling of exhaustion and overwhelm with ones assignment before the start of shift, this feeling occurs...

...Depression is a mood disorder in which feelings of sadness, loss, anger, or frustration interfere with everyday life for weeks or longer. It is normal for a teenager to feel sad or have uneasy feelings. When it doesn’t go away or stop, that is when it becomes a problem. It is actually more common in teens to go through depression. Grades, school, social status with peers, family, or life are some of the reasons why someone can be depressed. Holden Caulfield, from the story “The Catcher in the Rye”, was depressed because of some of these causes. He wasn’t able to find happiness and had severe guilt. The symptoms for depression can be really easy to spot. It is a change in behavior that you may see in someone. Depression symptoms can be different for every person. The more symptoms you have, and the longer you have them will more likely be that you are going through depression. All the symptoms will vary depending on what a teenager is going through. These are symptoms of depression: feeling hopelessness, appetite or weight changes, sleep changes, anger or irritability, self-loathing, concentration problems, and unexplained aches or pains. Other symptoms are excessive feeling of guilt, skipping school, sudden drop in grades, withdrawal from friends, and feeling sadness. Just like the way there are different causes for depression, there are also different way people will get treated for this. What may work for one person might not work for someone else.

...Grade Received, "A" Information systems will definitely alter the way that healthcare organizations are structured. Information systems were made to aide a business in having an aggressive lead over competition by giving support and helping to shape the makeup and strategies of the business. Upgrades to information technologies have raised the productiveness of healthcare services as well as employees because an advance in technology lowers the usage of paper records. These alterations in technology enable data to be distributed and reserved in exceptional ways, enabling information to be traced, evaluated, and exhausted in a manner that aides in delivering more competent care. Due to the type of data that is attainable via healthcare information systems, the makeup of the healthcare business will conform in consensus to the pertinent information systems. These systems will not only affect direct-care services like doctors and nurses, but will also alter non direct-care fields like analysis and growth, invoices, medical records, and more (Fottler, Ford, & Heaton, 2010). Fundamental alterations due to information systems are inescapable because of the alterations in how the data is acquired, reserved, and fetched. Information systems are intended to reply to inquiries. Nurses might exhaust upgraded systems to keep track of patients’ vitals; thus, altering the method of how care is given as well as the effectiveness of responses to the failing health of hospitalized consumers...

...A Sunny Day in Bryant Park Today was sunny, neither cold nor hot. After lunch, I hung out to Bryant Park to relax myself. There were a large number of people at that time due to the brilliant weather, I supposed. Nearly all the positions were occupied. Some were chatting with each other during the lunch time, happily and breezily. While some young boys enjoyed themselves going skating or playing tennis. Others, especially some old men and women would rather take nap in the leisure time. Under the heavy pressure in my studies, in fact, seldom had I observed people so carefully like this. In most cases, I always passed by the park as quickly as I could to save the time. It seemed that everyone had his own story and in different moods. It interested me a lot. While I was walking with no aim and destination, a slim woman with blonde hair suddenly caught my eye. Sitting on a chair at the corner of the park with an elegant posture and wearing headphones while indulging herself in the books, she frowned suddenly just like coming across some problems. A formal suit, a pair of delicate high heels, black coat on the chair. All these indicated that she was an office lady. Drinking a cup of Starbucks while skimming through the documents, she pulled the beautiful long black hair gently from time to time. She might work in the office not far away and have some tasks to deal with, which should have been finished in the morning. In the light of the exhaustion shown on her face, I thought...

...I accompanied my mother to the central market to buy some groceries that she needed for the coming New Year. When we arrived at the market we could not find a place to park the car. So we waited patiently for about ten minutes before someone vacated a parking space and we moved in. Coming to the market just before a festive season was not a pleasant experience. The whole town seemed to be there. Everyone had things to buy. So the prices of things shot up. Worst of all, we had to struggle to get these things. So we made our way carefully through the various sections buying vegetables, meat, fish, noodles, spices and other food stuffs. We had wanted to buy some prawns too but they were all sold out, despite their sky-high price. The bags got heavier and heavier. The crowd got thicker and thicker. The noise and heat was overwhelming. As we had nearly done all the shopping, I told my mother that I would wait for her at the car. I could not stand being among hundreds of aggressive shoppers anymore. I lugged the bags wearily to the car and breathed a sigh of relief when I reached it. The air smelled sweet and cool. I was glad to be outside. Fifteen minutes later my mother emerged from the market. She looked exhausted. We put the groceries in the boot, got into the car and drove off with the air-conditioner at full...
