Korean War vs. Vietnam War essays

Korean War vs. Vietnam War essays Korea and Vietnam had similar beginnings as far as revolutions are concerned. Korea had been occupied by Japan and Vietnam had been occupied by France. The United States and other U.N. nations put millions of dollars into both wars, but pretty much came out empty handed. At first it seemed as though America would win both wars but those opinions changed after years and years of fighting proved that not enough was being done to successfully rid Asian countries of communism. At first Truman just had sea and air suppport but it soon turned inot a war with the U.S.'s total involvment. A similar situation took place in Vietnam. In the beginning the U.N. sent support to France but soon got actively involved in the war once the support was not enough anymore. Korea, just like Vietnam was split between a Northern Communist enemy and a Southern Republic ally of the U.S. In both events the U.S. government was forced into signing peace treaties because of the severe U.S. losses from fighting. Both Vietnam and Korea were supported by China and the Soviet Union. By the beginning of the Korean War, China was already on its way to becoming a nuclear power. U.S. government officials faced problems with this. They needed to fight the main enemy but at the same time avoid a fight with China. Both sided knew that a fight with China would have meant World WarIII with a nuclear weapons. Both sides preferred to avoid this but either side was willing to use nuclear weapons if they detected a threat from the other side. For the U.S. both wars had similar goals. The stop of communism was imminent and the U.N. would do everything short of using nuclear weapons to stop it. The Vietnam war however brought on a new enemy, guerilla warfare. Guerilla tactics were powerful and could severly destroy operations in a sector. During the Korean war most of the fighting was done between two armies. But as far as Vietnam was concerned, U.S. troop...

Management of Chronic Pain for Patients With Breast Cancer Essay

Management of Chronic Pain for Patients With Breast Cancer - Essay Example The International Association for the Study of Pain defines it as: "An unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage." Subjectively it could denote any form of unpleasant sensation with varying degrees of intensity. Pain is distinguished based on two basic types identified as acute and chronic. Acute pain results from a disease process whereby there is inflammation or injury to tissues occurring rather suddenly after trauma or surgery and may be accompanied by anxiety or emotional distress. Usually certain medications serve to diminish the intensity of Acute Pain. Chronic Pain however, persists over a longer period than acute pain and is resistant to most medical treatments. Several factors may serve to heighten its perception and frequency thereby causing discomfort to patients in varying degrees. Pain follows a certain train of events before it is detected and proclaimed by a patient. Luckmann and Sorensen traced it to "the nerve receptors, named as nociceptors which differs from the complex receptors of vision and other senses". These nociceptors are simply free nerve endings in almost all types of tissues which react to change and require a high level of stimulation to elicit a response. However once their threshold is exceeded they communicate the presence of the painful stimulus. At times they become so over sensitized that long after the stimulus is removed, pain still persists. Once these nociceptors are stimulated, they discharge an impulse that travels in the form of an electrical activity to the spinal cord and on to the brain. The spinal cord is informed on the activity of the body through nerve fibers carrying somatosensory information. The spinothalamic tract then carries the painful information to the brain via the thalamus by passing through the somatosensory cortex which serves to localize and identify the quality of pain before it is diffused to the many areas of the brain including the reticular formation, medulla, hypothalamus and limbic structures. As a response, the brain sends to the receptors a complex response to the painful stimuli. It dictates the receptors to identify the degree, the character and intensity of the pain; its location and how to behave to reduce or avoid it in the future. "Pain can be inhibited if its pathways are blocked", as presented in the Gate-Control Theory of Melzack and Wall. The "gate" in their report is controlled by a dynamic function of cells that can facilitate or inhibit the transmission of pain signals. The fibers bringing pain information from the tissues are found in layers known as laminae. A certain Laminae II which is different from the rest of the layers and also called the Substantia Gelatinosa(SG) is proposed as the location of the "gate". This serves as the convergence point of all pain information, whether stimulus coming in from the tissues or identification from the brain. A spinal cord transmission cell also known as the t-cell either opens the gate thereby facilitating pain transmission or closing the gate. A variety of sources may close or open the gate but only the brain can manipulate the "gate" to inhibit or

Epidemiology exam Essay Example | Topics and Well Written Essays - 500 words

Epidemiology exam - Essay Example The Odd's Ratio would provide the estimated risk of prior patients, however the relative risk is also assessed looking forward to new ones. Therefore, a Cohort works best here because the assessment is looked at in terms of the mothers habits affecting the child in a forward manner. Birth weight, however, can be affected by infection, lack of support, no neonatal care, previous abortions, previous preterm births and other confounding factors. Reduction of effects would be done by a complete and thorough history of the patients prior to entering the study. B: The question involves an investigation into whether people who have worked in the factory of a chemical company producing toxic chemicals are more likely to develop a specific lung disease. This is a retrospective study or case-control since we are analyzing only one disease plus we are looking backward at people that already worked or were involved in a process prior to Time A looking backward to Time B.

Composition and Structure of Long Bone and Skeleton Function

Composition and Structure of Long Bone and Skeleton Function The composition of bone, the structure of the long bone and the function of the skeleton Composition of bone Bone itself consists mainly of collagen fibres and an inorganic bone mineral in the form of small crystals (University of Cambridge 2005). Bones are living tissue which is made up of connective tissue. The bone tissue is made up of several types of bone cells such as osteoblasts and osteoclasts. Osteoblasts are needed to aid the process of healing and osteoclasts are needed to break down old bone to make room for new bone. Bones contain phosphorus and calcium which are inorganic salts; these salts give the bone strength. The bone also has collagenous fibers to give the bone flexibility. Structure of the long bone The long bone consists of hyaline cartilage which covers the ends of the bone and stops them rubbing together as well as absorbing shock. The head of the long bone is called epiphysis. Compact bone is hard, dense bone and is the outer layer of the long bone, this gives the hallow part of the bone strength. Cancellous bone is the spongey bone in the long bone, which stores the red bone marrow and this is where blood cells are made. The yellow bone marrow is stored in the marrow cavity of the long bone and this is where white blood cells are made. Cancellous bone looks like honey comb as it is very porous and is easily recognised. The epiphyseal plate is where the bones grow in length. The shaft in the long bone itself is called the diaphysis. The periosteum is a protective layer on the long bone that has no cartilage; this is where the tendons and ligaments connect to (Curran 2016). Below is a picture of the structure of the long bone (LinkedIn Corporation 2017). Functions of the skeleton The functions of the skeleton include protection, movement, formation of blood cells and storage. Protection: Vital organs such as the heart and lungs are protected by the skeleton, the heart and lungs are protected by the sternum (breast bone) and the enclosure of the rib cage. The brain is also protected by the cranium (skull). Movement: Bones and muscles work together to produce body movement as a lever. Bones and muscles form joints which are needed to move. Formation of blood cells: This process is called haematopoiesis where blood cells are produced in the bone marrow of some bones. Storage: Bones store minerals such as calcium and phosphorus which are inorganic salts needed for the strength of bones. These materials are stored in the bones when there is too much present in the blood (Curran 2016). Types of joints and their functions There are three different types of joints; Fibrous joints, cartilaginous joints and synovial joints. Their main function is movement of the limbs and stability for example the stability found in the bones of the skull (Boundless 2016). Fibrous Joints Fibrous joints are immoveable i.e. they cannot move. These joints are held together with only a ligament. An example of this type of joint would be the cranium.   (Google Images 2017) Cartilaginous Joints Cartilaginous joints are partly moveable and the connection between articulating bones is made up of cartilage. An example of this type of joint is between the vertebrae that form the spine. The arrow in the below picture indicates where the cartilage is in the spine. (Google Images 2017) Synovial Joints Synovial joints are freely moveable and are the most known and common type of joints in the body. These joints have a synovial capsule surrounding the joint and the synovial membrane secretes synovial fluid to provide lubrication to the joint which prevents friction allows for more movement. Cartilage provides padding to each end of the bone. There are six types of synovial joints; hinge, pivot, ball socket, saddle, condyloid and gliding joints. Examples of synovial joints would be elbows, knees and hips (Boundless 2016).   Ã‚   (Google Images 2017)

Critical Analysis of Tuesdays with Morrie by Mitch Albom Essay

Critical Analysis of Tuesdays with Morrie by Mitch Albom Tuesdays with Morrie, written by Mitch Albom, is a story of the love between a man and his college professor, Morrie Schwartz. This true story captures the compassion and wisdom of a man who only knew good in his heart and lived his life to the fullest up until the very last breath of his happily fulfilled life. When Mitch learned of Morrie’s illness, the began the last class of Morrie’s life together and together tried to uncover â€Å"The Meaning of Life.† These meetings included discussions on everything from the world when you enter it to the world when you say goodbye. Morrie Schwartz was a man of great wisdom who loved and enjoyed to see and experience simplicity in life, something beyond life’s most challenging and unanswered mysteries. Morrie was a one of a kind teacher who taught Mitch about the most important thing anyone can ever learn: life. He taught Mitch about his culture, about trust, and perhaps most importantly, about how to live. One lesson Morrie teaches Mitch is about the view his culture has and how we, not only Mitch but also the rest of the world, should not believe what they say. Morrie tells Mitch: â€Å"Take my condition. The things I am supposed to be embarrassed about now — not being able to walk, not being able to wipe my ass, waking up some mornings wanting to cry — there is nothing innately embarrassing about them. It's the same for women not being thin enough, or men not being rich enough. It's just what our culture would have you believe. Don't believe it.† Morrie speaks these words of advice to Mitch during their eleventh Tuesday together, when they talk specifically about culture. Gradually, Morrie has come to accept his physical handicaps, just as he has come to accept his impending death. He complains that the culture is wrong to deem natural physical need as socially embarrassing, and thus he refuses to believe that his handicaps are shameful. In rejecting the values of the popular culture, Morrie creates his own set of customs, which accommodate the physical shortcomings popular culture finds disgraceful and embarrassing. As Morrie sees it, popular culture is a dictator under which the human community must suffer. He has already suffered enough from his disease, and does not see why he ... ...s that one must accept the possibility of one's own death before he can truly appreciate what he has on earth, as the sobering awareness that one day, it will all be out of reach, prompts the urge to appreciate and value what one can have only for a limited period of time, and to use every moment of that time doing something that one will not regret when the bird sings its last note. Morrie’s messages about life in this book were not solely directed fro Mitch; they are meant for anyone who is willing to take the time to listen. For me, there is not only one thing I learned from Morrie. I learned that I should not take life for granted because you never know when it will be over. Even though I have heard it many times I never really believed that what the media says is not necessarily true, until I read this book. Finally, I learned that love and compassion, not only for others, but also for oneself are essential in living a happy life. It does not matter if someone is rich, or if they are poor for that matter. The truth is that as long as you lived your life as best you could, you learned from your mistakes, and you are happy with yourself, then you lead a fulfilling life.

Ideal Work Environment (Iaps) Essay

Compensation: Our employees will be compensated by receiving a good compensation package for both the benefit of the company and the employee. The compensation package will include: †¢20% more income than the average salary per month †¢Guaranteed raises and bonuses based on job performance and/or time with company †¢Paid Volunteer Days †¢Time off unpaid †¢Vacation Pay †¢Health Insurance †¢Use of the company car Also, our company awards bonuses based on merit, these are non cash bonuses known as ‘Employee of the Month’, bonus day off, or a good parking space. Management: There are many qualities that make a good boss. At Honda Automotive Design Engineering, we have hired a boss that respects and has acquired all the expectations to lead this company to success and help improve the work environment in the building with weekly interactions with the employees. An effective boss will: 1. Set clear expectations 2. Coaches (someone who educates and encourages his employees as well as leads the company) 3. Gives feedback 4. Is inclusive 5. Gets to know employees 6. Works fearlessly 7. Is open and truthful (communication is essential) We view The Discussing Style as an effective management style because it promotes learning through interaction. In this style the manager encourages  critical thinking and lively discussion by asking employees questions about the problem, opportunity, or issue that must be resolved. The manager is a facilitator guiding the discussion to a logical conclusion. This style is effective because it’s based on communication, coaching, decision-making and recognition. Conflict: As executive officers, we manage workplace conflict by playing the role as an integrator. We seek to hear a variety of reasonable opinions and have an exchange of information before making a decision. This style of managing workplace conflict encourages creative thinking and is effective at problem-solving when issues are complex but it does take time. Hiring: This company hires employees that are compromisers when it comes to either conflict-management styles or working at this company in general. When compromising at this company, we force taking something from all parties involved and giving up something in return. When all parties to a decision are knowledgable and have good suggestions, this style results in good decisions. But when some parties contributing to the discussion are not fully informed, the final decision can be weak and we do not tolerate alienation, avoiding or domination. We are looking for 3 types of positions: Architects, Mechanic/Engineers, Designers (All must have a designing degree). Culture: At Honda Automotive Design Engineering, we create a community feeling in the building. Our offices are designed for employees to have lots of space, freedom and wide communication with the other employees. To prevent worker alienation, we have created our offices to be a happy and comforting atmosphere and in order to do that we changed plain, boring, simple office spaces into warm colourful walls and more open space for communication but  also providing separation walls so the room does not becoming loud or chaotic, enough for a functioning workplace. Recruiting the best employees possible will be simple giving them special accommodations, for engineers we provide them with tons of space in the building and utilities. For designers, we provide all the utilities, essentials, workspace and organization products (files, compartments etc.). Equity: To meet the needs of a diverse worker population, we aim for employees with different ethnicities and personalities. We ensure that the work environment is a safe space free of harassment by 24/7 security on building grounds, employees have the right to complain and/or notify authorities and the manager, and we hire employees that are open-minded about gender, race, religion and sexual orientation. We do not tolerate any kind of harassment in the workplace and we also provide rules towards that topic. The Honda Automotive Design Engineering is redesigned to maximize productivity and employee satisfaction for the work environment. On the graph 7.6 (page. 206), we think that our employees would rate their job/workplace regarding economics fairly well because we provide job security, fair/reasonable pay, health plans and a paid vacation. Also, Contribution and involvement would be rated excellent because we allow employees to work the way they want in their office space, they can make a difference to improve the companies growth and production as well as participate in decision-making.

Actinium Facts - Element 89 or Ac

Actinium is the radioactive element that has atomic number 89 and element symbol Ac. It was the first non-primordial radioactive element to be isolated, although other radioactive elements had been observed before actinium. This element possesses several unusual and interesting characteristics. Here are the properties, uses, and sources of Ac. Actinium Facts Actinium is a soft, silver-colored metal that glows pale blue in the dark because the radioactivity ionizes air. Actinium reacts with moisture and oxygen to form a white coating of actinium oxide that protects the underlying metal from further oxidation. The shear modulus of element 89 is estimated to be similar to that of lead.Andre Debierne claimed discovery of an element he named actinium, working from a sample of pitchblende supplied by Marie and Pierre Curie. Debierne was unable to isolate the new element (which modern analysis reveals might not have been element 89, but rather protactinium). Friedrich Oskar Giesel independently discovered actinium in 1902, calling it emamium. Giesel went on to become the first person to isolate a pure sample of the element. Debiernes name was retained because his discovery had seniority. The name comes from the Ancient Greek word aktinos, which means ray or beam.The actinide series of elements, a group of metals between actinium and lawrencium possessing similar properties, takes its name from actinium. Actinium is considered the first transition metal in period 7 (although sometimes lawrencium is assigned that position).Although the element gives its name to the actinide group, most of the chemical properties of actinium are similar to those of lanthanum and other lanthanides.The most common oxidation state of actinium is 3. Actinium compounds have similar properties to lanthanum compounds.Natural actinium is a mix of two isotopes: Ac-227 and Ac-228. Ac-227 is the most abundant isotope. It is primarily a beta emitter, but 1.3% of decays yield alpha particles. Thirty-six isotopes have been characterized. The most stable is Ac-227, which has a half-life of 21.772 years. Actinium also has two meta states.Actinium occurs naturally in trace amounts in uranium and thorium ores. Because its difficult to isolate the element from ore, the most common way to produce actinium is by neutron irradiation of Ra-226. Milligram samples m ay be prepared in this manner within nuclear reactors.To date, there has been minimum industrial use of actinium because it is rare and expensive. The isotope actinium-227 might have use in radioisotope thermoelectric generators. Ac-227 pressed with beryllium is a good neutron source and may be used as a neutron probe for well logging, radiochemistry, radiography, and tomography. Actinium-225 is used for radiation cancer treatment.  Ac-227 may also be used to model water mixing in the ocean.There is no known biological function for actinium. It is both radioactive and toxic. It is considered slightly less toxic than the radioactive element plutonium and americium. When rats were injected with actinium trichloride, about half of the actinium was deposited in the liver and one-third into the bones. Because of the health risk it presents, actinium and its compounds should only be handled with a glove box.
