Abstract
The purpose of this paper is to introduce and discuss the book " Blood of My Blood: The Dilemma of the Italian Americans," by Richard Gambino. Specifically it discusses several important themes in the book in which Gambino attempts to change the publics' perception of Italian-Americans and encourage more empathy with their problems and their culture.
From the Paper
"The book is partly a study of Gambino's own life, growing up in Red Hook, Brooklyn in a "typical" Italian-American family, and partly a study of Italian-Americans as a whole. Gambino speaks of how Italian-Americans tend to cluster together in their own sections of a city, called "Little Italies." Gambino gives us figures and numbers, but more than that, he gives us an intimate look at the family, the culture, and the strong ties to home that each Italian-American carry with them. "At least 85 percent of the total of Italians who immigrated to the United States, and perhaps 90 percent of those who came in the great flood of immigration from 1875 to 1920 were from areas south and east of Rome" (Gambino 3)."

From the Paper
"Global warming is one of the most pressing global environmental issues. There is ample evidence that global warming is occurring and that it will have fundamental effects on global climate. For example, in "Impact of global change and forest management on carbon sequestration in northern forested peatlands" [1]Martin Lavoiet et al note, "The atmospheric concentration of CO2 has increased by 31% since 1750 and is expected to double by the end of the 21st century, reaching 720 ppm (parts per million) (IPCC 2001).""

From the Paper
"General circulation models (GCM) are used to evaluate past, present, and future climatic phenomena. Climate consists of a region's prevailing weather. Variations in climate are primarily determined by the combined influences of the atmosphere, the continents, and the oceans. Such effects can both foster and hinder human activities. Consequently, considerable effort has been devoted to climate modeling.
In recent years, GCMs have been the primary tool used for climate simulation. These numerical representations describe climatic change in three-dimensions. The models involve numerous data inputs. In addition, they also require various ... "

"GLOBAL WARMING & OCEAN CIRCULATION
This research reviews the literature relevant to the relationship between global warming and ocean circulation. Global warming is considered both in the context of natural warming and warming induced by human activity.
The circulation of the ocean normally involves the sinking of cold water in higher latitudes and the replacement of that cold water with warm water from lower latitudes (Schneider, 1989). This process "allows the inflow of warn surface currents that in turn warm the air above and held maintain relatively ice-free conditions" in the higher latitudes (Schneider, 1989, p. 47). These ocean currents cause regions such as western Europe to have moderate climates while other regions at similar latitudes, such as Siberia and northern Canada, have harsh, cold climates. The ..."

Abstract
This paper discusses how there is a fear, which continues today, regarding safe blood and HIV and how beyond contamination, there is another serious blood issue and that involves blood shortages. It describes the actual function of the blood to the body, how blood cells regenerate, and the principles of blood transfusions. It shows that duplicating all the functions that blood performs in the human body would seem to be an impossible challenge and how any artificial blood product must pass several tests. It also looks at current research into synthetic blood production from two distinct directions, one based on chemicals and the other based on hemoglobin.
From the Paper
"What function does blood actually provide within ? and for ? the body? According to the assigned article in Scientific American, blood ?transports nutrients, hormones and waste products?; blood also fights infections and has the ability to ?clot? ? preventing or at least slowing down serious hemorrhaging. The part of human blood which helps fight disease is the white blood cells. But the most ?familiar? function of blood in the body of mammals is the ?capture and release of oxygen and carbon dioxide.? The protein most commonly found in blood, hemoglobin, is also a critically important protein. Hemoglobin picks up oxygen in the lungs, and distributes it throughout the body. The red blood cells pick up carbon dioxide, which is a waste product given off through the respiration of cells, and humans exhale the carbon dioxide out through the lungs."

Abstract
This paper describes the circulation of blood through the body and the heart in detail, naming all the vessels and parts of the heart. It looks at inflammation and blood clotting, and the role of the circulatory system in maintaining homeostasis in the body.
From the Paper
"An oxygenated red blood cell enters the ascending aorta and passes into the descending aorta then into the left iliac artery to the left femoral artery finally arriving at the knee still in its oxygenated state. Once there, the oxygenated red blood cell travels into small arteries which supply blood to the knee and into arterioles which are even smaller arteries. These pass the oxygenated red blood cell along to the capillaries where the oxygen it is carrying along with nutrients..."

Abstract
This paper looks at many factors relating to blood,including different cell types, Rh factor, serum constituents, how it circulates throughout the body and blood tests. The paper also looks at the average lifespan of red cells and explains the implications of higher than normal red cells.
From the Paper
"The average adult male has between five and six liters of blood and the average female has between four and five liters. The color of blood is determined by the state of oxygenation of its red cells. When blood leaves the heart it has been oxygenated in the lungs and therefore arterial blood is bright red. When blood has passed through the tissues oxygen has been removed from the red cells so the blood appears dark red in the veins. Nutrients carried in the blood include..."

Abstract
This paper compares the use of a blood pressure cuff on the forearm, as opposed to the upper arm, for monitoring blood pressure. To make the comparison, the paper looks at a medical case where the blood pressure of a patient had to be obtained on an hourly basis in order to administer her required medication. The paper also reviews current literature about this method of measurement.
From the Paper
"A clinical case in which blood pressure was measured by placing the cuff on the forearm is N.L.; a 78-year-old widowed African American female from Memphis, TN. She is disabled and dependent on her two daughters, which she lives with, for most of her activities of daily living. N.L. was admitted to the intensive care unit at Baptist Memorial Hospital-Memphis on July 16, 2005 for hemorrhagic cystitis and respiratory distress. She has no known drug allergies. Past medical history includes congestive heart failure, hypertension, myocardial infarction, diabetes mellitus, right below the knee amputation, morbid obesity, and sleep apnea. She has also had a tracheotomy since 2003 to treat her sleep apnea. N.L. was treated for respiratory distress upon admission by mechanical ventilation with a mode of Assist Control and 40 percent oxygen, which she was weaned from on July 18, 2005. She was also placed on Dobutamine drip, July 17, 2005, at three micrograms per kilogram per minute for management of a secondary diagnosis, congestive heart failure. The administration of this drug requires hourly blood pressure measurements. Blood pressure was measured with the cuff placed on the forearm, because large sized cuffs were too small for her upper arm due to her existing state of morbid obesity. "

Abstract
The writer details the different blood types which are in critically low supply, while explaining that blood is the fluid of life, transporting oxygen from lungs to body tissue, and extracting carbon dioxide from body tissue to lungs. The paper goes on to explain the different types of donations needed, including double red cell donation which is an automated procedure that allows one person to give two units of red blood cells, resulting in one donation helping two patients.
From the Paper
"There are four main components, red blood cells, platelets, plasma, and white blood cells. Red blood cells carry oxygen to body tissues and remove carbon dioxide. A red blood cell has a flat, disk like shape. It resembles a doughnut with a thinner middle and thicker edges. There are approximately one billion red blood cells in two to three drops of blood. Platelets are disk like structures that help stop bleeding. For example if a blood vessel is cut, platelets together and form around the edge of the cut, a plug like stopper. After donation, platelets have a shelf life of only 5 days. Plasma is the liquid portion of the blood, a protein-salt solution in which red and white blood cells and platelets are suspended. It makes up about 50 to 60 percent of the total volume of blood. Plasma serves a variety of functions, from maintaining a satisfactory blood pressure and volume to supplying critical proteins for blood clotting and immunity. White blood cells are responsible for protecting the body from invasion by foreign substances such as bacteria, fungi and viruses. Most of the cells are round and colorless. White blood cells produce proteins called anti-bodies that destroy bacteria and viruses. In the blood stream, there is only one white blood cell for every 600 red cells."

Blood and "Macbeth", 2005.
An analysis of the use of blood imagery in William Shakespeare's "Macbeth".
1,611 words (approx. 6.4 pages), 5 sources, MLA, $ 52.95

Abstract
This paper examines how William Shakespeare successfully uses blood imagery in his play "Macbeth" to illustrate the drastic change in Macbeth's character. Blood imagery is powerful because blood is essential for life and every time we see blood, we are reminded of life. It looks at how the images of blood are all linked to Macbeth throughout the play, from the first images of blood connected with loyalty, to the blood imagery connected with justice at the end of the play.
From the Paper
"Blood is a powerful image to the audience and to Macbeth. After he kills Duncan, Macbeth says, "Here lay Duncan, /His silver skin laced with his golden blood" (II.iii.130-1). The murder of Banquo brings even more bloody imagery. At the feast, it becomes apparent that Macbeth is becoming unstable because he cannot distinguish between what is real and what is not. He thinks he sees Banquo's ghost at the table and blurts, "Blood hath been shed ere now, i' th' olden time" (III.iv.87). Here we see, like the blood and guilt in the previous scenes, Macbeth cannot wash this blood away, either. In fact, the image becomes more intense, which intensifies Macbeth's reactions to it. It is more real to him now because he is slipping."

Abstract
This paper discusses the general properties of blood and then goes on to compare the abundance and safety of the blood supply in the world and the U.S. The paper concludes by discussing which government agency is responsible for ensuring the safety of the American blood supply.
Outline:
Introduction: What is Blood?
What is the Situation as far as a Clean Blood Supply in the World?
In the United States, the Blood Supply "...is Among the Safest in the World,"
Which Government Agency is Responsible for Ensuring the Safety of the American Blood Supply?
From the Paper
"Blood is one of the circulating fluids of the body that serves as nutrition, carrying oxygen, nutrients, and metabolic waste. The average adult has about five liters of blood that travels through the heart, arteries, veins, capillaries and cells. The plasma of the blood, according to Gray's Anatomy (pp. 1077-1078) has within it corpuscles, some of which are colored red. There are about four to five million red corpuscles in the average person's blood, and about 12,000 red corpuscles "in each cubic millimeter of blood." In general, the red corpuscles carry oxygen and other nutrients and the white corpuscles fight disease. As a person gets older, and the size of his or her blood vessels change (usually shrinking), the red corpuscles "change their shape...as to adapt themselves to some extent to the size of the vessel," according to Gray's Anatomy."
