...Angela Maguire Prof. David Gilhousen PHSC 210- Elements of Earth Science July 24, 2015 Radiocarbon Dating: Faith of Fact Introduction Archeologist and other scientists have used many different dating methods to establish the age of the earth and things on the earth. One of the dating methods that has been used is radiocarbon dating, also known as Carbon-14 dating. Radiocarbon dating is a prejudiced method that can be used to prove the desired outcome. Like many other methods, radiocarbon dating is inconsistent and constantly changing. The root of a scientist’s belief must come from a more stable foundation. Although, Old-earth and young-earth scientists agree on carbon-14 half-life, the scientists differ in areas such as finding C-14 in rocks and diamonds. To begin, we must first describe the process of radiocarbon dating. The half-life of Carbon-14 has been measured at 5,730 years. Therefore, the assumption has been made that radiocarbon dating is only valid to be used on objects older than 100,000 years. Morris (2011,63) describes the process in this way, “Carbon-14 is formed when nitrogen -14 interacts with a cosmic ray-produced neutron in the upper atmosphere”. This new isotope is only a small part of the total carbon. Within the isotope there is a ratio of Carbon-12, a stable carbon, to Carbon-14, a non-stable carbon. The isotope is incorporated into carbon dioxide, which is then breathed in by all living organisms. When living organisms are alive, the radiocarbon...

...Pathophysiological Processes: Coronary Artery Disease Andriy Melnychenko Chamberlain College of Nursing NR 283: Pathophysiology June 9, 2018 Pathophysiological Processes: Coronary Artery Disease Coronary artery disease (CAD), also known as coronary heart disease (CHD), is the most common type of heart disease and is the leading cause of mortality in the United States. CAD is responsible for around one – third of all deaths (Chen, M. A. 2015). CAD causes the coronary arteries to narrow and harden. Coronary arteries are the blood vessels of the heart. They are responsible for oxygenation of the heart and supplying it with blood. The biggest blood vessels of the heart are the right and left coronary arteries.

...The Rental Heart is a short story written by Kirsty Logan. In this science fiction story we follow the main characters use of rental hearts. You can rent hearts as many times as you want to, and you can put them in your chest, so whenever you get your heart broken, you can just go to the rental store and rent a new one, and that’s what this story is about. The Rental Heart isn’t written chronologic, so it leaps in time. In this story the narrator also uses flashbacks: “Jacob was as solid and golden as tilled field, and our love was going to last forever, which in our age meant six months. Every time Jacob touched me, I felt my heart thud wetly against my lungs”. In the beginning we hear about the main character telling us, that is was the day after he met Grace he went to the rental store, where he hasn’t been for over ten years. When we hear what he thinks of Grace and the rental hearts, we get a feeling of a problem. We don’t know how many years the story courses, but we’ll assume that it’s from the main character is a teenager, to he is an adult person, because he tells us that his first love was meant to last forever and at their age it meant six months. We can tell that the story takes place in future, because you can rent hearts. The main character can be both a man and a woman, because the person is attracted both sexes, and therefor is bisexual. The story is written in first person narrator, and we hear the story from the main characters point of...

... 1. The paramedics noticed the empty bottles of wine, the temperature of the water, and the length of time the couple has been dead. 2. Did any of them have an alcohol problem? Did any of the Underhill’s have health issues? Could you notice any signs of suicidal actions? Where they stressed people? 3. The pill Lasix is used for swelling and fluid retention, also used to treat high blood pressure. Also the stress from their everyday job could have had an influence. 4. For Mr. Underhill to potentially have high blood pressure the alcohol helps to expand blood vessels in the body and increase body temp. Alcohol also has the same effect and both of them together plus his high blood pressure could have cause him to have a severe heart attack or stroke. As for Mrs. Underhill, she could have pass out because of dehydration and drown. 5. I believe they died because of the alcohol and the hot temperatures of the water. Drinking dehydrated the body and with the hot water causing them to sweat also they where dehydrated at an unhealthy level. The depressant feeling in alcohol plus the hot temp of the hot tub could cause one to fall asleep or lose consciousness. PART 2 1. I believe Mr. Underhill taking the medicine, drinking, and in the hot water lowered his blood pressure to unhealthy levels causing him to pass out, and Mrs. Underhill, I believe she passed out from her alcohol consumption and died from going under water. 2.

...Memorandum TO: Professor Erika Oquinn FROM: Alla Hajeh DATE: 3/17/2013 SUBJECT: Heart Transplant After a very thorough and intensive process I have decided to give the heart to Lisa. This was a very tough decision to make and although every one of these people deserve this heart I have found it to be in the best interest of everyone that Lisa gets the heart. The utilitarianism theory and hedonistic utilitarianism have greatly affected my thinking and have helped me come to this conclusion. The utilitarianism theory is based upon that the greatest good for the greatest number should be the main consideration in making a choice. Also, the second theory goes hand in hand where there is more pleasure than pain when more people benefit from the greatest good for the greatest number (Weijers, 2011). So in that pleasure is more important and needs to be valued where pain shouldn’t. Below I will describe more thoroughly the process I went through and the factors I determined in concluding my decision. * Jerry: This candidate is 55 years old and although with this heart his chance of survival is another 10-15 years old there are many people his age that die of heart attacks, strokes, etc. The other candidates are younger and haven’t experienced the many wonders of life this man probably has like the simple things, falling in love, getting married, having children, etc. His children are at an older age where they understand life and death. His kids can soon all get...

Under stress circumstances your heart pounds faster, blood pressure rises, breath quickens ,your senses becomes sharper. These reactions increases your stamina, speeds your reaction, and enhance your focus preparing you to either fight or flee (Tennant, john hopkins university schools of education, 2005) .it is optimistic when a person feels stimulated and able to manage the situation, handle emergencies meet challenges and excel. (Tennant, 2005) But there is no doubt that the negative effects dominates over the positives. .

...MECHANISM OF BREATHING Breathing occurs when the contraction or relaxation of muscles around the lungs changes the total volume of air within the air passages (bronchi, bronchioles) inside the lungs. When the volume of the lungs changes, the pressure of the air in the lungs changes in accordance with Boyle's Law. If the pressure is greater in the lungs than outside the lungs, then air rushes out. If the opposite occurs, then air rushes in. Breathing Rate The rate at which we inhale and exhale is controlled by the respiratory center, within the Medulla Oblongata in the brain. Inspiration occurs due to increased firing of inspiratory nerves and so the increased recruitment of motor units within the intercostals and diaphragm. Exhalation occurs due to a sudden stop in impulses along the inspiratory nerves. Our lungs are prevented from excess inspiration due to stretch receptors within the bronchi and bronchioles which send impulses to the Medulla Oblongata when stimulated. INSPIRATION Inspiration occurs when the chest cavity enlarges. As the thorax enlarges, the lungs expand along with it, and air rushes into them and down the alveoli. Muscles of respiration that are classified as inspiratory muscles include the diaphragm and the external intercoastals. The diaphragm is the dome shaped muscle separating the abdominal cavity from the thoracic cavity. The diaphragm flattens out when it contracts during inspiration. Instead of protruding up into the chest cavity, it moves...

...cavity to the alveoli and then from the alveoli to the oral or nasal cavity to be released back into the atmosphere. With sleep apnea the passageway becomes completely obstructed and keeps oxygen from entering the bloodstream. Awake, the airway muscle tone helps keep the airways patent. While asleep, decreased airway muscle tone and the pull of gravity in the supine position, further decrease the size of the passageway. As the disease progresses, the passageway becomes more and more obstructed as tissue collapses. It is diagnosed by checking oxygen levels in blood, testing heart, lung, and brain activity, and checking breathing patterns while you sleep. It is more common among men, and there have recently been patterns found among the Asian community. Although, anyone can develop the disease, obesity, smoking, and other diseases can lead to sleep apnea. Untreated, sleep apnea can be the cause of depression, heart disease, diabetes, and fatal car crashes. There are several treatments for sleep apnea. Continuous positive airway pressure (CPAP) involves a CPAP machine which delivers a consistent level of air pressure to your...

...I. INTRODUCTION A. Number of cases/Statistic data of the disease A.1 Statistics Accurate pre-eclampsia statistics are difficult to obtain because the condition ranges from extremely mild to severe. Mild cases are sometimes not included in official figures. Furthermore, mild cases may have no effect on pregnancy, which is why the figures for pre-eclampsia as a whole are higher than for those that actually complicate pregnancies. Around 10% of pregnant women develop pregnancy-induced hypertension (high blood pressure) or pre-eclampsia (high blood pressure with protein in the urine).Worldwide more than four million women per year will develop pre-eclampsia, and over 63,000 maternal deaths are due to pre-eclampsia. Action on Pre-Eclampsia estimates that every year in the UK pre-eclampsia is responsible for the deaths of six mothers and 500 to 600 babies. A 2005 to 2006 study showed a promising fall in the numbers of women developing eclampsia since 1992, from 4.9/10,000 to 2.7/10,000. This has arisen as a result of the introduction of management guidelines for eclampsia and pre-eclampsia. Pre-eclampsia is much more common in first pregnancies, and there is a reduced incidence of pre-eclampsia in the second pregnancy. The risk of women who have had pre-eclampsia developing it again in future pregnancies is 16 percent, and 25 percent if they suffered from severe pre-eclampsia, eclampsia or they delivered pre-term. This rises to 55 percent if their baby was delivered before...
