Abstract
This paper describes, in detail, three different types of microscopes and explains why a microscope is so vital to the success of the modern criminalist. The paper examines the value of hair as trace evidence, and describes the morphology of hair in detail.
From the Paper
"Microscopes are vital to the job of the criminologist. Several different types of microscopes aid them in their work. Compound microscopes are light illuminated. The image seen with this type of microscope is two-dimensional. This microscope is the most commonly used in science. John Ross explains that the parameter for a compound microscope involves the power of the microscope. The power is usually engraved on the eyepiece as a number X X or X. Power is frequently misunderstood and often overstressed in the initial..."

Abstract
This paper explains that there are several different types of atomic force microscopes, which are used at very close ranges and without a lens, that operate by measuring a local property, whether height, optical absorption or magnetism, by using a probe placed very close to the sample. The author points out that AFMs constitute a subset within the larger group known as scanning-probe microscopes, which can utilize many different types of tips. The paper relates that the accuracy of the AFM depends on the state of the tip and a worn tip can produce blurred images resulting in the recent development of an automatic tip evaluation system showing when the tip needs to be replaced.
From the Paper
"Kevin Kjoller considers how to measure the true resolving power of an atomic force microscope, noting first that resolution means the same as it does for an optical microscope, meaning the minimum distance between two adjacent objects that a microscope can identify as separate. Kjoller complains that most manufacturers substitute some meaningless term for resolution and ignore the reality. Several issues need to be considered, such as the size of the probe and three types of limiting noise, electrical, mechanical, and acoustic. Kjoller defines electrical noise as "the sum of the thermal and operating noise from all components inside the AFM electronics, including any noise due to cross-talk and less-than-optimal grouping.""

"The Confocal Microscope
Invention of the first microscope occurred about 1600 A.D. (3:39). As technology advanced, by 1887 improvements in resolution enabled John Buist to observe the small pox virus (3:40). Then, throughout the 20th century, progress in the field of microscopy accelerated (3:40). Ernst Ruska's invention of the electron microscope around 1930 increased resolutions by orders of magnitude (3:40). This was quickly followed by the development of phase contrast, differential interference contrast, and fluorescence microscopy techniques (11:183). It was the widespread use of fluorescent probes..and the background glare they produced..which eventually led to the development of the confocal microscope (3:40).
The first confocal microscope was invented by Minsky in 1955..."

Abstract
Under the microscope, distinctions between coniferous (soft) or non-coniferous (hard) woods can be seen. Soft woods are, as a rule, more simple in construction than hard woods. The writer discovers that this is the reason soft woods are preferable in making paper.
Table of Contents:
Introduction
Analysis of Hard and Soft Woods
History of Paper
Modern Paper Production
Recycled Paper
Conclusion
From the Paper
"Paper is the dry sheet form of an aqueous deposit of any vegetable fiber. It has been in common use for so long, we often take it for granted. We forget that our trees are being cut down at an alarming rate to produce virgin paper. However, recycling processes are trying to slow this trend. The making of paper has been refined to almost art form; indeed, some people create handmade papers as an art. While it can be made from a variety of vegetable fibers, such as hemp and cotton, trees have long been the main source for the fibers."

Abstract
This paper discusses a form of toxoplasmosis caused by a microscopic parasite called toxoplasma gondii, found in all warm-blooded animals like pets, livestock and human beings. It explains that the disease is transmitted from a mother contaminated with toxoplasma at the time of pregnancy to unborn child; eating under-cooked or uncooked meat of infected animals or eating food, drinking water or inhaling contaminated dust. The author points out that pregnant women can become infected by swallowing cat feces from a toxoplasma-infected cat; therefore, pregnant women should not empty the litter-box of cats. The paper relates that medication of opportunistic infections (OIs) like toxoplasmosis needs some intricate trial-and-error to determine the best treatment for an individual patient.
From the Paper
"The cure of toxoplasmic retinochoroiditis intends killing free Toxoplasma organisms before they can attack host cells, as well as the encysted parasite, without aggravating the situation as an effect. Folate synthesis inhibitors, mainly pyrimethamine and sulphadiazine, have been most regularly used to cure all groups of patient with toxoplasmic retinochoroiditis. These, and the protein biosynthesis inhibitor clindamycin, are useful against the extra-cystic form of Toxoplasma. Instantaneous treatment at the beginning of symptoms is a logical approach to therapy. This could lessen the probability of re-invasion by Toxoplasma of other host cells, and the extent of disease process, as well as the possibility of ensuing extension and reappearance. Systemic corticosteroids are also widely used in the healing of vigorous incidents of toxoplasmic retinochoroiditis. Treatment with glucocorticoids, including progesterone, can restrain antimicrobial activity of macrophages, and thus may have an effect on the result of steroid therapy for ocular toxoplasmosis."

Abstract
This paper discusses issues of race and the struggle for identity, which are at the heart of Trethewey?s four poems. The author points out that, by employing skilfully techniques of imagery, symbolism and metaphor, and by utilizing concrete details, Trethewey is able to communicate effectively the difficulties she experiences as a so-called ?mixed breed". The paper relates that, in ?Flounder?, which is about a fish, the title also means to struggle awkwardly as one moves, again illustrating Trethewey?s struggle with her own identity.
From the Paper
"For instance, in the poem ?White Lies,? her play on words is extremely effective, as she lies about being white. These lies, Trethewey tell us, are told ?in a black place?, which illustrate what her mother has told her about her race. Clearly, Trethewey?s mother told her daughter she was black, even though she did not look it. The poet is able to express her confusion over the matter when she can tell others she is white and get away with it--not to mention when others automatically assume she is white, as the classmate does when she holds her hand in an act of unity."

Abstract
Tardigrada, also known as water bears for their appearance, are one of nature?s most interesting animals and comprise one of the earth?s most diverse phyla. The paper shows that as they continue to be discovered in diverse habitats around the globe, they continue to amaze scientists with their evolutionary adaptations. The paper explores the physicalities of phylum tardigrada including their digestive and sexual reproduction systems.
From the Paper
"The 800 or more species of tardigrades are difficult to decisively place in one area on the tree of life. However, recently it has been decided that tardigrades belong to a large group of molting animals which includes Drosophilae and C. Elegans. They have been included in many different branches along the tree of life such as Infusoroa, Annelida and Arthropoda. Tardigrada was first identified as a phylum by G. Ramazzotti in 1962. Recent studies have set a new proposal that contains the molting animals including: arthropods, tardigrades, onychophorans, nematodes, nematomorphs, kilnorhunchs and priapulids. In this analysis the morphological similarities are used to relate tardigrades."

Abstract
This essay discusses recent discoveries in evolutionary studies, including the human genome project, and will speculate on the impact that these new discoveries will have on evolutionary studies. The paper concludes that we can look forward to substantial and possibly profound breakthroughs in terms of understanding what it is to be human, but warns that we should not expect to find the meaning of life with our microscopes.
From the Paper
"For example, since the completion of the human genome project, scientists have achieved another milestone: they have completed the genetic map blueprint of the chimpanzee. Due to the chimpanzee's close relationship to humans (in evolutionary terms), we now have the opportunity to better understand the evolutionary processes that have combined to create human beings. The scientific analysis has revealed that some 96% of human and chimp genomes are exactly the same. More important still are the insights provided by the differences between human and chimp genomes."

Abstract
This paper studies "Ceremony", a novel by Leslie Marmon Silko about native Americans. The paper analyzes how the novel seems to be focused on the most minute, bleak and tawdry details and yet it is actually commenting on the broadest realities, the deepest human longings and powers. The author of this paper demonstrates how Silko is microscopic in her portrayal of Tayo, the novel's main character. Through a discussion of Tayo's life experiences, character development and emotions, the paper asserts that Silko ultimately contrives her books so that Tayo can finally see the pattern -- the way in which all his stories fit together.
From the Paper
"Silko can be unrelentingly microscopic in her attention to detail. She tells you more than you ever wanted to know about what it feels like to be really drunk, and really poor, and totally desperate, and guilty, and remorseful. She captures the dismal ambiance of cheap bars in Gallup, makes you know what it feels like to be a native American in despair at the loss of his people's honor and dignity--not to mention their land and their heritage. But she doesn't tell you in an elevated tone, through an essay or a lecture. She hits you at a gut level with all the violence and the vomit that accompanies alcoholism, poverty, and hopelessness. Silko doesn't just say that whites and Indians mistrust each other and treat each other badly. She uses the way Tayo's Auntie Thema, a Christian Indian, treats her half-white nephew, her subtle facial expressions and unexpressed anger and embarrassment, to reveal the subtleties of hatred and mistrust that characterize the underlying racial themes of the book."

Abstract
The paper describes the origins of the telescope. It includes a brief history of the magnifying glass and the first spectacles from which the beginnings of the first telescope evolved. The writer discusses Galileo's part in the development of the telescope and explains the changes from the Galilean model through to the reflecting telescope developed in the mid 1700s. In summation, the paper explains that the telescope has led to other important inventions such as the microscope.
From the Paper
"The cost of quality glass had come done enough by the end of the thirteenth century and the quality was reasonable enough that it was becoming a real possibility for people to be aided in their eyesight problems as they reached their middle years. It was discovered by spectacle makers that they were able to enhance vision for people by shaping and polishing glass in such a way that the words were enlarged. This is what is known today as the magnifying glass and had become common by the middle of the thirteenth century. From here came the invention of the spectacles and as the glass lenses were made smaller and it was learnt what could be done by altering shapes and polishing the glass in various ways the beginnings of the telescope evolved."

?Song of Myself?, 2005.
This paper explores major nature imagery from Walt Whitman's "Song of Myself", originally written in 1855 and often considered to be his finest work.

Abstract
This paper explains that Walt Whitman's lengthy poem "Song of Myself", which is partially autobiographical and completely introspective, resembles Jean-Jacques Rousseau's earlier work "Meditations of a Solitary Walker" and certain transcendental works of William Blake. The author points out that Whitman's work belongs to the Romantic Movement, which swept through European and American literature during the nineteenth century; relying heavily on emotionalism, the individuality of the writer and the writer's communing with him or herself and nature. The paper relates that Whitman's use of a first person narrative, alternating between a macroscopic representation of humanity and a microscopic view of the poet, creates the work's idealism and insight. Several long quotations.
From the Paper
"In this passage, Whitman is taking one of the simplest, perhaps most simplistic elements of nature, the frequently ignored blade of grass and placing it in the curious eyes of a child. The choice of a child's question is most appropriate, since a young person, new to the wonders of the world, is likeliest to be amazed by grass, as he or she tends to be with most elements of nature. However, many parents find themselves at a loss for a ready answer when confronted with such questions, as they are with "What is thunder?" Whitman admits this frustration, as he feels unable to answer the child; ironically, the answer he provides offers incredible insight. He first discusses religious optimism in terms of hope and the grass being God's own signature."

Abstract
The article focuses on the importance of Steinbeck's indigent farm workers: the so-called "Okies", as described in his novel, "The Grapes of Wrath". It analyzes their importance by utilizing three critical appraisals that have the "Okies" under the microscopic, so to speak. The papers describes the "Okies" with a narrow aperture, as well as a universal perspective.
From the Paper
"Reed's examination of language usage in his article is quite different. He is more interested in the use of crude language, and the various meanings this usage implies. He focuses on the language operating within the various communities. This becomes apparent for the reader, in passages like the following: "Just as derogatory language becomes more vile in the mouths of middle class than among the migrants, so unpleasant details are more savage in the established community" (608)."
