Abstract
In this article, the writer maintains that developers of research designs need to take all relevant processes into account if their results are to have validity. The writer notes that many researchers conducting functional magnetic resonance imaging (MRI) tests fail to take the time of day into consideration. The writer points out that this can lead to error given that cortisol levels are different throughout the course of a day. This is important because cortisol can cross the blood-brain barrier and bind to receptors in the hippocampus and frontal lobe. The writer explains that this can then have an impact on the neural activation/deactivation process, meaning the BOLD (blood oxygen level dependent) in the MRI study and produce results that will not be properly interpreted unless the time of day is included as a variable.
From the Paper
"Higher levels of cortisol are associated with stress, and cortisol levels vary throughout the day just as levels of stress will vary throughout the day. Because cortisol can cross the blood-brfain barrier and bind to the hippocampus, levles of cortisol can have an effect on the neural activation and deactivation of the BOLD levels and so alter the results of the MRI. Time of day thus becomes an element in the process so that the clinician knows what time of day the examination was made and how high the levels of cortisol might be at different tiemns of the day."

Such diagnoses could potentially save millions of lives.
Outline:
Introduction
Pathologies and Diagnosis discovered through the use of MRI
Conclusion
From the Paper
"In addition to pancreatic cancer and brain abnormalities MRI's can now be used to detect track inhaled or dissolved gases in the body. According to Kadlecek (2002) methods to examine the localized changes or abnormalities in lung structure and function were difficult to come by. The two most common types of diagnostic tools are spirometry which is the measurement of exhaled air volume and the speed at which it is expelled and the other diagnostic tool is chest x-rays, both conventional x-rays and those performed with CT scans (Kadlecek 2002). However when Helium-3 polarizers, are used in combination with magnetic resonance imaging (MRI), it can also be used as a diagnostic tool and permit the microscopic examination of lung structure and localized studies of lung function, which were not previously possible (Kadlecek 2002).

From the Paper
"The use of computed tomography (CT) and magnetic resonance imaging (MRI) present both advantages and disadvantages relative to imaging for the diagnosis of brain disorders. While the MRI typically yields superior visibility of the suspected brain tumor mass, CT is superior to the use of radionuclide scans to set primary intracranial lesions. Further, while MRI does not "see" (image) bone, thus making it superior to CT for suspected intracranial brain tumor, its viability in scanning for vascular disease is as of yet unproved. In addition to these, contrast- ... "

Abstract
In July, 1977, an event took place that would forever alter the landscape of modern medicine. Outside the scientific research community, this event hardly attracted any notice at all. The event in question was the first MRI exam ever performed on a human being. The procedure required almost five hours to produce one image, and the images were, by today's standards, very primitive; however, its successors number in the thousands today. The advent of the MRI clearly represented the beginnings of a new standard in noninvasive radio-imaging that continues to be refined. This paper provides the background and history of magnetic resonance imaging, including its discovery and evolution and newly identified applications for the technique. A summary of the research is provided in the conclusion.
From the Paper
"MRI provides an unparalleled view inside the human body. The level of detail we can see is extraordinary compared with any other imaging modality. MRI is the method of choice for the diagnosis of many types of injuries and conditions because of the incredible ability to tailor the exam to the particular medical question being asked. By changing exam parameters, the MRI system can cause tissues in the body to take on different appearances. This is very helpful to the radiologist (who reads the MRI) in determining if something seen is normal or not. We know that when we do "A," normal tissue will look like "B" -- if it doesn't, there might be an abnormality. MRI systems can also image flowing blood in virtually any part of the body. This allows us to perform studies that show the arterial system in the body, but not the tissue around it. In many cases, the MRI system can do this without a contrast injection, which is required in vascular radiology."

Abstract
This paper analyzes the disappearance of the Mayan civilization while focusing on the various theories surrounding its eventual collapse. The writer of this brief yet concise paper details the history of the Mayan culture which emerged in 2000 BC. The Mayan civilization gave birth to numerous cultural progresses such as the establishment of a writing system, an organized political council as well as the introduction of organized religion. This paper examines the theories surrounding the dispersal of the Mayan civilization, when at around 800 AD it was purported to have suddenly collapsed. There have been numerous arguments based on archaeological and anthropological evidence that attempted to explain the collapse of this particular civilization. This paper focuses on several theories which may explain the disappearance of the Mayan people which include climatic changes as well as socio-cultural collapse through the population's expansion.
From the Paper
"The theory that argued that a climatic collapse led to the disappearance of the Mayan civilization was based from scientific findings that were caused by a severe drought. As reported by History Today, "[d]rilling samples from the Cariaco Basin off the Venezuelan Coast show there were intensely dry periods between AD 810 and AD 910..." From this finding, it was found that because there had been scarce supply of the people's basic needs, such as water and food supply, Mayan society disappeared, supposedly due to deaths caused by these series of drought. A more specific version of this theory was presented in Kerr's journal article on the scientific evidence pointing at climate changes as the catalyst towards the disappearance of the civilization."

From the Paper
"In traditional rural settings in their own country, Vietnamese women also experienced less economic power than their male counterparts; however, women were vitally involved in the task of rice cultivation, from which most Vietnamese earn a livelihood. The Vietnamese adage, "Men plow, women transplant, the buffalo pulls the harvest" reflects the traditional gender division of labor in the process of rice cultivation. According to Kibria, "Women not only played an important part in rice cultivation but also did most of the household work. Women were responsible for childcare and housework and for taking care of household gardens and livestock." Nevertheless, in spite of their important roles in a wide range of economic activities, women's economic participation continues to be regarded as being secondary and peripheral to that of men, who are considered to be the primary breadwinners in rural Vietnamese society."

Abstract
The paper discuses magnetic resonance imaging (MRI). The paper examines how MRI provides morphological and functional information, and today is the primary technique used in the routine diagnosis of many disease processes. The paper further examines how MRI is non-invasive, uses non-ionizing radiation, and has a high soft-tissue resolution and discrimination in any imaging plane. The paper further discusses the technology of the Upright MRI, and its uses.
From the Paper
"As the technology of weight-bearing MRI has developed, so too have new applications, from gynecologic to cardiovascular evaluations, as well as new challenges in interpreting the complex images that are now available (Wendling 2005). In 2000, the Fonar Corporation introduced the Upright MRI, which can scan a patient in virtually any position that reproduces pain or other symptoms, thus allowing the detection of pathologies visible only in a variety of weight-bearing positions, including standing, sitting, fexion, and extension (Wendling 2005)."

This paper details Jefferson's numerous achievements in various areas including: Architecture, farming, literature, mathematics as well as drafting the Declaration of Independence. This informative paper contains a detailed biography of Jefferson's life including historical dates and relevant information pertaining to his political and presidential career.
From the Paper
"Controversies were rampant as Jefferson led a non-importation agreement and called for a meeting of all the colonies to consider their grievances. Although he was ill and could not attend the First Virginia Convention where the Virginia delegates were going to be elected, he sent a paper giving his views of the crisis. In the paper, he argued that Parliament had no control over the American colonies and that when the original settlers came to America, they had used their natural rights to emigrate. He claimed that the colonies still owed allegiance to only the king, and he aligned the colonists with the Saxons who settled in England from Germany hundreds of years earlier."

Abstract
This paper explains that some experts believe that today's parents are stifling their children with constant worrying and supervision and are denying children learning opportunities for risk-assessment and challenge needed to develop self-confidence. The author points out that confidence is the key to child-rearing. The paper relates that parents are often quick to judge a child's actions or choice of words and neglect to see that at times they are actually cries for love, attention or help; therefore, it is important to acknowledge a child's feelings and opinions and try to understand a situation from their point of view.
From the Paper
"A good parent is constantly worrying about their children because there seems to be infinite dangers lurking everywhere. Should a parent vaccinate or not vaccinate, should one parent be a stay-at-home parent or should both parents work outside the home? There is such a myriad of advice available and much of it conflicting over everything from potty training and playing, reading and sleeping, to socializing and eating, it is difficult and frustrating to know whom to believe and trust. Then there are the everyday hazards, such as pedophiles, child kidnappers, rapists, poisonous plastics, choking hazards, sudden death syndrome, chemical contamination of food, and child equipment recalls. It is enough to make any parent paranoid, guilt wracked, angst-ridden, and lose many nights of sleep due to a fear-filled mind."

From the Paper
"The defense industry is largely oligopolistic, with the federal government the sole customer, or "monopsonist". The industry consists of relatively few very large contractors and many small satellite subcontractors which cluster around them. The business of a contractor in defense work comprises research and development and/or production. The work can vary from exploratory studies, costing thousands of dollars, to extensive production programs involving billions and requiring broad subcontracting arrangements. In practice, the firm that does the research and development often contracts the production work as well.

From the Paper
"Throughout history, war has bred innovation of all kinds, for both good and evil. This has never been truer than in World War II. This was a period of frantic military innovation unrivaled in history. Inventions ranging from UFO's to wire guided missiles like the HS 293 were implemented for the first time (7,12). Though many of these ideas were drawn up decades before the proper technology became available, many of them were surprisingly effective."
