The main cause of Skin Cancer is exposure to the sun. Caucasians are more at risk for skin cancer because people with Darker Skin are more evolved to black out the sun. The age that Skin cancer typically occurs is after 50. The incidence of skin cancer is greater in older individuals. The amount of light reaches the North and South Poles in a predictable manner. The map shows all one color near the poles. The latitude that receives the greatest amount of UV light is the equator. Based on this information, the darkest pigmentation of skin is along the equator. The lightest Pigmentation of skin is near the poles. The more darkly pigmented skin will be near the equator because there is more UV light there, and the pigment protects the skin more. The graph describes the reflectiveness of skin at different locations. The pattern for skin reflectiveness is the skin is less reflective near the equator. The closer people are to the equator, thew more their skin needs protection. This means that their body produces a darker pigment. This gives the skin less reflectiveness. These findings match the answer to number 6. If there are lighter skin colors near the equator, it could mean the people migrated there many years ago, and their skin hasn't adapted yet. Skin colors have evolved because our bodies need to change to survive. The factor most likely to change our skin color is the amount of UV light our bodies get. In question 3, the answer was that people over 50 are more likely to get skin cancer. After reading this article, the likeliness of getting skin cancer not only goes with age, but also on exposure to UV light and the persons genetics. My answer to question 9 still seems likely, but now there are more factors to add in. In order to see which people get skin cancer the most, you would have to take that persons

...(b. 460 B.C.E.) and to figures such as Galen of Pergamum (c. 130–c. 200), who contributed much to early understanding of anatomy and physiology. The tradition of natural history dates back to the work of Aristotle (384–322 B.C.E.). Especially important are his History of Animals and other works where he showed naturalist leanings. Also important is the work of Aristotle's student Theophrastus (d. 287 B.C.E.), who contributed to an understanding of plants. Aristotle and Theophrastus contributed not only to zoology and botany, respectively, but also to comparative biology, ecology, and especially taxonomy (the science of classification). Both natural history and medicine flourished in the middle ages, though work in these areas often proceeded independently. Medicine was especially well studied by Islamic scholars working in the Galenic and Aristotelian traditions, while natural history drew heavily on Aristotelian philosophy, especially in upholding a fixed hierarchy of life. The Roman naturalist Caius Plinius Secundus (23–79), known as Pliny, also had a major influence on natural history during the middle ages, notably through his compendium Natural History (later shown to be rife with errors of fact). Without doubt the most outstanding contributor to natural history in the middle ages is Albertus Magnus (1206–1280), recognized for his superb botanical studies and for his work in physiology and zoology.

Skin Cancer and Tanning

...SKIN CANCER & TANNING The idea of a “healthy tan” is a myth which must be corrected in order to reduce the increasing incidence of skin cancer in the world. An individual's skin color is determined by their genes and their environment. Our skin can change color in reaction to sun exposure. This is called the "tanning response." When skin absorbs UV radiation, melanin is produced and transferred to the keratinocytes cells within the skin thereby darkening the color of the skin. Melanin in the skin absorbs and scatters UV radiation entering the body and helps protect the skin from adverse reactions to radiation. Thus, the "tanning response" is really a defensive reaction by the body to the presence of damaging radiation, and an effort by the body to protect itself from the harmful affect of ultraviolet A and ultraviolet B (UVA and UVB) rays (“Anatomy”). A tan still remains in the minds of many as socially desirable. Each day we are confronted with images on television and in magazines of golden-brown models and celebrities. In addition, we are the targets of local advertising and promotion of tanning salons. People must understand that a tan is not necessary; and that in addition to the premature aging of the skin, there are serious and possibly deadly consequences from the overexposure of one’s body to UVA and/or UVB rays. The deadly consequence is skin cancer. When people think of cancer they relate to the threat of colon cancer, breast cancer, lung cancer, prostate...

Athrophaneura Semperi

...[pic] I. INTRODUCTION “I embrace emerging experience. I participate in discovery. I am a butterfly. I am not a butterfly collector. I want the experience of the butterfly.” -William Stafford With the rise of knowledge about endangered species and diminishing protected ecology, it is becoming essential to study and get involved with this very tragic trend in our environment. Butterflies are one of the many insects that require attention. Despite of their usefulness, conservation of butterflies in our country is seemingly neglected This research aims to focus in Atrophaneura semperi. A butterfly species, considered endemic in the Philippines. (backpackingphilippines.com/2008/10/lep…) Not only has my huge interest in butterflies led me to pursuing this topic but also a certain curiosity about this specific species and how widely spread it is in the Philippines and all over the world. I would like to discuss its importance, the reproductive cycle, and the protection programs offered for their specific case, as I go through the next chapters of this study. Data generated could be used for species monitoring, biogeography, conservation program and creation of database information of butterflies in the Philippines as economic development and climate change progresses.

Dove Case Study

...Beauty Case Study By: Melinda Brodbeck and Erin Evans Presented March 5, 2007 SITUATION: The Dove Campaign for Real Beauty (CFRB) began in England in 2004 when Dove’s sales declined as a result of being lost in a crowded market. Unilever, Dove’s parent company, went to Edelman, its PR agency, for a solution. Together, they conceived a campaign that focused not on the product, but on a way to make women feel beautiful regardless of their age and size. The following summer, CFRB was brought to the United States and Canada. CRFB aimed not only to increase sales of Dove beauty products, but also targeted women of all ages and shapes. According to the CFRB website, “The Dove Campaign for Real Beauty is a global effort that is intended to serve as a starting point for societal change and act as a catalyst for widening the definition and discussion of beauty. The campaign supports the Dove mission: to make women feel more beautiful every day by challenging today’s stereotypical view of beauty and inspiring women to take great care of themselves.” In addition to changing women’s view of their bodies, Dove also aimed to change the beauty market. In an industry where the standard of beauty is often a size two blonde supermodel, Dove distinguished itself by using models that ranged from size six to fourteen. CRFB abandoned the conventional cynical method of portraying “perfect” women as beauty role models. RESEARCH: Dove commissioned The Real Truth About Beauty study as a...

This chapter introduces you to these fundamentals of brain anatomy. Before you begin this chapter, I want to apologize for the lack of foresight displayed by early neuroanatomists in their choice of names for neuroanatomical structures— but, then, how could they have anticipated that Latin and Greek, universal languages of the educated in their day, would not be compulsory university fare in our time? To help you, I have provided the literal English meanings of many of the neuroanatomical terms, and I have kept this chapter as brief, clear, and to the point as possible, covering only the most important structures.

According to ancient Vedic texts (and later through Tantric and Taoist traditions), the energetic, or subtle, body is the foundation of the food, or coarse body, and the bridge between the physical and causal realms. Therefore, the structure of the subtle energetic body provides an intended means for human spiritual development, or evolution (which enables humanity to fulfill its purpose as a conduit between heaven and earth, hence transforming into an entity more subtle, and original). The text’s primary purpose is to present oriental bio-energetic theory, and second, to bridge theoretical gaps between Traditional Chinese Medicine (TCM) and Ayurvedic Medicine, through the comparisons of their energetic structures, which are fundamental to the esoteric alchemical systems inherent within the theories of exoteric medicine. Furthermore, the work intends to reveal even deeper realizations and correspondences of the origins of esoteric alchemical tradition (eg.Tantra,...

...is pathophysiology? • How are etiology and pathogenesis used to predict clinical manifestations and response to therapy? • How are normal and abnormal physiologic parameters defined? • What general factors affect the expression of disease in a particular person? • What kinds of information about disease can be gained through understanding concepts of epidemiology? http://evolve.elsevier.com/Copstead/ • Review Questions and Answers • Glossary (with audio pronunciations for selected terms) • Animations • Case Studies • Key Points Review Pathophysiology derives from the intersection of two older, related disciplines: pathology (from pathos, suffering) and physiology (from physis, nature). Pathology is the study and diagnosis of disease through examination of organs, tissues, cells, and bodily fluids. Physiology is the study of the mechanical, physical, and biochemical functions of living organisms. Together, as pathophysiology, the term refers to the study of abnormalities in physiologic functioning of living beings. Pathophysiology seeks to reveal physiologic responses of an organism to disruptions in its internal or external environment. Because humans exhibit considerable diversity, healthy structure and function are not precisely the same in any two individuals. However, discovering the common and expected responses to abnormalities in physiologic functioning is useful, and it allows a general prediction of clinical progression, identification of possible causes...

Here, he takes a loot at the endlessly fascinating topic of human sexuality His convincing arguments should persuade xm that there are very special reasons why we evolved to use sex for recreation as well as for procreatim whereas most other mammals are denied that pleasure.... It is a great little book, by one of the worlds foremost biological philosophers." -ROGER Shohl Professor of Physiology Monash University Australia "Once again Jared Diamond provides us with answers to questions we may never have stopped to ask, but wish we had. In this long essay Diamond explains that recreational sex, while not unique to humans, is a rare behavior in the animal world.

In some cultures, however, dogs are also a source of meat.[7][8] In 2001, there were estimated to be 400 million dogs in the world.[9] Most breeds of dogs are at most a few hundred years old, having been artificially selected for particular morphologies and behaviors by people for specific functional roles. Through this selective breeding, the dog has developed into hundreds of varied breeds, and shows more behavioral and morphological variation than any other land mammal.[10] For example, height measured to the withers ranges from 15.2 centimetres (6.0 in) in the Chihuahua to about 76 cm (30 in) in the Irish Wolfhound; color varies from white through grays (usually called "blue") to black, and...

Gift of Consiousness

...Understanding the Gift of Consciousness 2008 Timothy Lynch COMP 111 5/14/2008 The brain is the most complex and most fundamental of all the human organs. It is the essence of life. It is the vehicle through which man perceives reality, experiences, interprets his body’s sensory information, and coordinates all communication through billions of neural connections to various organs and systems, regulating and maintaining homeostasis (processes for maintaining internal stability). One’s experiences of life, their acquired skills, and the lessons learned are contained within a brain’s wrinkled, corrugated, and almost alien structures as memories. Two main categories of memory exist independently and simultaneously, short-term and long-term. Short-term, also known as working memory, is the mind’s way of temporarily storing any relevant information and task-specific data. There are at least two varieties of Short-term memory. One of the memory types is called by the name ‘phonological loop.’ This is how your brain stores linguistically encoded information for short periods of time (only seconds). The other is the visuospatial sketchpad, the mind’s way of maintaining, its visuospatial relationship(s) for the same short time as the phonological loop.(Foster, 972). The alternative memory format is Long-term or, declarative memory. The three inherent and pre-determined protocols the brain uses to remain functioning to translate a person’s experiences as this...

Lichen

...Lichen /A lichen is a composite organism that emerges from algae[->0] or cyanobacteria[->1] (or both) living among filaments of a fungus[->2] in a mutually beneficial (symbiotic[->3]) relationship.[1][2][3] The whole combined life form has properties that are very different to properties of its component organisms. Lichens come in many colors, sizes, and forms. The properties are sometimes plant-like, but lichens are not plants. Lichens may grow like a tiny, leafless, branching shrub (fruticose[->4]), like it has leaves (foliose[->5]), like a crust of paint on a surface (crustose[->6]),[4] or have other growth forms.[5] A macrolichen is a lichen that is either bush-like or leafy. A microlichen is everything else.[1] Here, "macro" and "micro" do not refer to size, but to the growth form.[1] Common names for lichens[->7] may contain the word "moss" (e.g., "Reindeer moss[->8]", "Iceland moss[->9]"), and lichens may superficially look like and grow with mosses, but lichens are not related to mosses or any plant.[3]:3 Lichens don't have roots that absorb water and nutrients like in plants.[6]:2 Instead they produce their own food from sunlight, air, water, and minerals in their environment.[7] They are not parasites[->10] on the plants they may grow on, but only use them as a substrate to grow on or in.

Arguments for and Against Euthanasia in Terms of Teleological and Deontological Theories

...ABSTRACT The most important general and theoretical horizons regarding bioethics refer to the foundation of ethical theories. We can talk about two main general categories in which we can place the ethical theories: teleological and deontological. From the first category we enumerate the Aristotelian perspective or the one developed by J. St. Mill, while the Kantian perspective is exemplary for deontological ethics. According to the teleological perspective, a form of human behavior is described as moral or non-moral according to the goals explicitly set. The mere achievement of these goals is a necessary and sufficient condition to qualify as moral people’s actions or deeds without taking into account the “intermediate stages” of the actions performed to achieve those goals. Deontology, as a general horizon of articulating the ethical theories, believes on the contrary that in every moment of our existence, every action or deed that we accomplish can be described as moral or non-moral according to the ethical principles underlying our behavior. The very important consequences arising from the two general theoretical horizons concern two different perspectives on “human nature”, or what we call the essence of the human being. Starting from this horizon we will have the consequentialist and deontological dimensions related to euthanasia. The bioethical dimension in which we will discuss the issue of euthanasia involves both dimensions or horizons. The arguments against...
