...One of the quickest ways to intimidate a tough football player, ask them to donate blood. My high school’s annual blood drive is sponsored by the Doctors of Tomorrow club; a club I am the treasurer of and have been actively involved with since my freshman year. Every year one of our biggest challenges with the blood drive is meeting donor quotas. Knowing that each year about ten percent of the people signed up won’t be able to donate, it is essential we have enough people signed up in order to get enough blood. To most students it does not appear to take much work, but every club member knows that it’s success is the result of many hours of work and collaboration. Preparation for the blood drive, which takes place in October, starts in May....

...In August 2011, on one of the main roads that runs through Google’s headquarters in Mountain View, California, a Prius—one of the cars in Google’s fleet of autonomous vehicles—caused a fender-bender. The accident happened, naturally, because there was a human behind the wheel. That's according to a new report by Google about its self-driving car project, a document that tallies every accident since it began testing its 32 vehicles on the roads in 2009. That sounds like it could be a massive dataset, considering the tens of thousands of accidents that happen on American roadways each year. It actually isn’t: “In the six years of our project, we’ve been involved in 12 minor accidents during more than 1.8 million miles of autonomous and manual driving combined,” Google wrote. “Not once was the self-driving car the cause of the accident.” Not once! In the case of the fender bender four summers ago, a Google employee—yes, a human—was to blame. He had borrowed the car to run a quick errand and ended up rear-ending another car. (“He was not using the vehicle to test our autonomous technology,” Google wrote, and the car ended up sustaining “some damage.”) So what ended up being probably a pretty bad day for that Google employee—imagine telling your boss you crashed the driverless car—turns out to be a tidy example of the key difference between human drivers and algorithmic ones. Namely: Robots are much, much better drivers than humans. Google’s descriptions of the other accidents...

...Los Angeles alone, there are over 400 separate gangs and an estimated 39,000-gang member. The most common gangs that are in the Los Angeles area are the Bloods and the Crips. Both are recognized but the “colors” that they wear. Bloods wear bandanas, or other articles of the clothes that have a red color, Crips wear blue. Though they are known by their distinct colors, these two gangs are rival enemies. Also, they can be recognized by the different tattoos an individual has, there are certain marking each gang member will have. Every year young children are joining these gangs in hopes to fit or belong somewhere. But, getting into these gangs isn’t easy there are initiations. The most common initiation would be "Blood in - Blood out.” This is particularly initiation the “Blood-in” refers to assaulting or murdering someone. “Blood-out” refers to the death of the member whether by his/her own death or at the hands of a gang member. Violence is not the only thing that is gangs are known graffiti, or "tagging." is one way the gangs mark their territory. By tagging an area, the gang might want to make their presence known or it may be a way of letting people knows where they are selling drugs. Other Violence includes drive-by shootings, four teen-agers were wounded in a drive-by shooting and, by the end of 1989, and several drive-bys were being reported each week. One December, a 19-year-old man became the first...

...Introduction Heart failure is a condition in which the heart cannot pump enough blood through the body. When this happens, parts of the body do not get the blood and oxygen needed for them to function properly. This can cause symptoms such as shortness of breath, fatigue, and confusion. There is no cure for heart failure. However, following your health care provider's instructions about a healthy lifestyle and being treated with medicines can help you stay active and live longer. The types of medicine you are prescribed will depend on your symptoms and what is causing the heart failure. In some cases, you may need to take more than one medicine. It is important to talk to your health care provider about all the medicines you are taking, how...

...1984[edit] Ten-year-old Tre Styles (Desi Arnez Hines II) lives with his single mother Reva Devereaux (Angela Bassett) in Inglewood, California. After Tre gets involved in a fight at school, his teacher calls Reva and informs her that although Tre is rather intelligent, he is immature, aggressive, and lacks respect for classmates and adults alike. Frightened about the future of her child, Reva sends him to live in the Crenshaw neighborhood of South Central with his 27-year-old father, Furious Styles (Laurence Fishburne), from whom she hopes Tre will learn valuable life lessons. On the night of Tre's arrival, he hears his father shooting at a burglar who tried to rob the house. LAPD officers arrive more than an hour later, and eventually decide the crime is unimportant because nothing was taken and the burglar escaped completely unharmed. The police, particularly the African American officer, treat Furious with disrespect and contempt. The following day, Tre reunites with childhood friends Darrin "Doughboy" Baker, Doughboy's maternal half-brother Ricky, and Chris, their mutual friend. While Ricky is naïve and trusting, Doughboy is aggressive and street-smart. The next day, Chris takes the group into another neighborhood to view the decaying corpse of a murdered gang member. A Crip gang member tricks Ricky into giving up his football, prompting Doughboy to confront him to get it back. Doughboy is beaten up, but the ball is returned to him by another Crip member. Furious...

...Gangs Gangs have been a part of American Society for many years now. Some people would argue that gangs started around the 1950s (Made in America video). However the notorious gangs that most people know of, the Bloods and the Crips did not form until later. Many people question why young men and even kids join gangs, and there can be different answers to that question. However many people can agree that gangs and gang involvement is deviant act. The question now is what type of deviant organization are gangs, according to me, I believe that gangs are organized crime groups, or also a deviant family outlook. I believe that gangs are organized crime groups because gangs make up 48% of violent crimes (www.fbi.gov). Gangs take part in many different violent acts such as murder, theft, rape, kidnaping and etc… That is because gangs compete with other rival gangs, and when asked why they fight most gang members did not have a reason why. (Made in America Video). However they said if they kill one of us, than we go and kill three of them, it is that type of attitude that has led to 48% of violent crimes. (Made in America Video). Gangs to me are also organized crime groups because they participate in drug manufacturing, trade, and distribution which has to be carefully operated, without it being organized there would not be a profit made. Participating in all these different activities within the gang is what leads me to believe that they are an organized crime group. Another question...

Distinguish between a) open and closed circulatory systems; b) single and double circulation; c) pulmonary and systemic circuits (Pages 889-901). 2. Coordinated cycles of heart contraction drive double circulation in mammals. De-oxygenated blood from the body enters the heart, which is then pumped to the lung to be oxygenated. The newly oxygenated blood enters the heart and then pumped to the whole body. Use the structures given below to describe the direction of blood flow. Start with the first structure that takes the de-oxygenated blood to the heart and end with the last structure that takes the oxygenated blood to the body (Pages 902, Fig 42.6).

...Keara Williams Carol Ann Jenkins Master Student 22 April 2008 Multiple Endocrine Neoplasia Type 1 When some children are born, they have a disorder that is passed from one parent or both through the genes that are the basis for their being alive. These diseases are called genetic disorders. Some of these disorders are rare and don’t have a cure. One such disease or disorder is Multiple Endocrine Neoplasia Type 1, or MEN1. I will explain what this disorder is and what body systems it affects. MEN1 is a relatively uncommon inherited disorder where less than 1 person in 20,000 will carry the gene. It is passed down in families from 1 generation to the next and affects males and females equally, it occurs in all racial groups. This disease can be inherited if only one parent has MEN1. Diagnosis of the disease is done through genetic testing or following a patient medically over several years and seeing if the patient has symptoms of the disease. MEN1 affects the endocrine glands: the pituitary, parathyroid, and pancreas glands that regulate different hormones that control the functions of various tissues throughout the body. Normally, the hormones released by endocrine glands ore carefully balanced to meet a body’s needs. In patients with MEN1, the endocrine glands may become overactive at the same time or throughout a lifetime. Similarly, different areas of within the endocrine glands may become overactive at different times during life. By age 30 most people who...

The foetal lungs are filled with fluid and are not required for gas exchange.1 Oxygenated blood in umbilical vein mixed with portal venous blood from the foetus, reaches right atrium through the Inferior Vena Cava with an oxygen saturation of 67 %.2 Immediately after delivery the transition from foetus to new born involves extensive changes in all the systems but the most crucial changes occur in cardiovascular and pulmonary system. After the first breath post-delivery, fluid in the lung pushes out and the lungs will be filled with oxygen and the oxygen content in...

...evaluate the process of discovery, development, future trends and potentials for artificial blood vessels as a medical device and promising technology in cardiovascular treatment. This is the technology that will provide great health benefits to the patients and is more cost effective then traditional methods like coronary bypass. Coronary heart bypass has a number of disadvantages, for example, procedure can not be carried out if patient has not got a vessel with a sufficient quality standard. Also a coronary heart bypass procedure is a long duration operation and has a higher risk of further infections with additional pain and discomfort for the patients. Use of artificial blood vessels provide a more advantageous type of surgical procedure for patients and surgeons, reducing time, risk of infection and pain in...

...fluid. E. How would Cari’s lungs compliance (the effort required to expand the lungs) be altered as her alveoli fill with fluid due to pneumonia? Her lung compliance will increase from trying to force the gases into and out of the alveoli. The fluid that is in her lungs is pneumonia. F. How would fluid in Cari’s lungs affect her total lung capacity? The fluid in her lungs affect her total lung capacity by decreasing the amount of air into them since there is fluid buildup. G. How does the elevation of Cari’s respiratory rate alter her minute ventilation? Cari’s minute ventilation would rise. Minute ventilation is determined by multiplying the total volume by respiratory rate. H. Normal blood oxygen saturation levels are greater than 94 percent; Cari’s blood oxygen saturation level was 90 percent at the time of her exam...

If there is not gradient, there will not be an increase of transport, so more Glut-4 doesn’t always increase uptake. 11. a) This is incorrect because if there is more glucose ingested, the Glut-2 would allow glucose to be...

...This quarter in class I have learned a lot about interpersonal relationships and how important friendships are. Friendship is a lot like food. We need it to survive. What is more, we seem to have a basic drive for it. It is found that human beings have fundamental need for inclusion in group life and for close relationships. I came across an interesting article written by Rick Naurt that was published in the March 2010 edition of Psychology Today. In the article Naurt writes about how important it is to have friendships and it can be dangerous to become lonely. Evidence has been growing that when our need for social relationships is not met, we fall apart mentally and even physically. There are effects on the brain and on the body. Some effects work subtly, through the exposure of multiple body systems to excess amounts of stress hormones. Yet the effects are distinct enough to be measured over time, so that unmet social needs take a serious toll on health, eroding our arteries, creating high blood pressure, and even undermining learning and memory. Nuart’s article goes into depth about how a lack of close friends and a dearth of broader social contact generally bring the emotional discomfort or distress known as loneliness. It begins with an awareness of a deficiency of relationships. This cognitive awareness can play through our brain like an emotional soundtrack and make us sad. We can start to feel emptiness within ourselves and may be filled with a longing for contact...
