...What Is Selenium? Selenium (Se) is a trace mineral that is required by the human body and is of fundamental importance in ensuring good health. Selenium was discovered in 1817 by Jons Berzelius and takes its name from the Greek word Selene (the goddess of the moon). Until recently, selenium was a little-known trace mineral. International research on Selenium has established that it is an essential component of the human diet in the sustaining of good health and general well-being because of its protective and preservative characteristics. It has also been found that selenium deficiency may lead to increased susceptibility to disease and ill health. Organic And Inorganic Selenium Explained Selenium exists in two chemical forms in nature, Organic Selenium and Inorganic Selenium. Inorganic Selenium can be found in different minerals in the form of selenite, selenate and selenide as well as in metallic form. In contrast, in vegetable feed Organic Selenium is an integral part of amino acids. Therefore, in nature animals receive selenium mainly in the organic form. Research had shown that Organic Selenium is far more beneficial for us as our body absorbs and retain Organic Selenium at a better rate. Organic Selenium vs Inorganic Selenium Organic Selenium Inorganic Selenium • Exists in the form of seleno-amino acids, i.e. selenomethionine. • Exists in the form of mineral salt. • Is actively absorbed by amino acid routes. • Is passively absorbed from the small intestine. • More...

...Selenium Reference Concepts A command is what tells Selenium what to do. Selenium commands come in three 'flavors': Actions, Accessors and Assertions. Each command call is one line in the test table of the form: |command |target |value | Actions are commands that generally manipulate the state of the application. They do things like "click this link" and "select that option". If an Action fails, or has an error, the execution of the current test is stopped. Many Actions can be called with the "AndWait" suffix, e.g. "clickAndWait". This suffix tells Selenium that the action will cause the browser to make a call to the server, and that Selenium should wait for a new page to load. Accessors examine the state of the application and store the results in variables, e.g. "storeTitle". They are also used to automatically generate Assertions. Assertions are like Accessors, but they verify that the state of the application conforms to what is expected. Examples include "make sure the page title is X" and "verify that this checkbox is checked". All Selenium Assertions can be used in 3 modes: "assert", "verify", and "waitFor". For example, you can "assertText", "verifyText" and "waitForText". When an "assert" fails, the test is aborted. When a "verify" fails, the test will continue execution, logging the failure. This allows a single "assert" to ensure that the application is on the correct page, followed by a bunch of "verify" assertions to test form field values...

...Ecosystem Structure, Function and Change Ecosystem Structure, Function and Change In the area that I live in we have the San Luis National Wildlife Refuge. The refuge is over 26,800 acres of wetlands, riparian forests, native grasslands, and vernal pools (U.S. Fish & Wildlife Service, 2012). In 1966 was when the first piece of land was purchased, and since then it has grown to comprise of six refuge units. The units are called: San Luis, East Bear Creek, West Bear Creek, Freitas, Blue Goose, and Kesterson. If it were not for the refuge many animals would have lost their homes and there would actually be a few extinct species of animals as well. In the San Luis National Wildlife Refuge there are four different types of ecosystems. The first type of ecosystem that can be found in the refuge is riparian woodlands. The riparian woodlands are found along rivers and sloughs, and they consist of willows, cottonwoods and oaks ( U.S. Fish & Wildlife Service, 2012). The second type of ecosystem that can be found is wetlands. Wetlands include permanent marshes which contain water year-round. However depending on how much rain the refuge gets in the winter depends on the level of water in the wetlands. Grasslands are the third type of ecosystem in the San Luis National Wildlife Refuge and that type of ecosystem is actually the most common one in the refuge. The grasslands are dominated by annual and perennial grass species. The last of the ecosystems that is found in the...

SQA tools are the specially developed software tools for the purpose of assisting in the QA processes. 1.1 Software Quality The quality of software is assessed by a number of variables. These variables can be divided into external and internal quality criteria. External quality is what the user experiences when running the software in its operational mode. Internal quality refers to the aspects that are code-dependent, and are not visible to the end-user. External quality is critical to the user, while internal quality is meaningful to the developer only. When the quality comes to software quality conformance, requirement consider as software functional quality and fitness for use named as software structural quality. 1.2 Software Quality Assurance Software quality assurance (SQA) consists of a means of monitoring the software engineering process and methods used to ensure quality...

...that all living things breathe. The mining technique called mountaintop removal needs to be stopped from destroying the fragile ecosystem that revolves around the streams that are the bloodlines that run through southern West Virginia. This style of mining not only strips the land of all vegetation, it also changes the water. Excess sediment from mining builds up over time causing the oxygen levels to change (S. Burns, 05). Over time this makes it imposable for the stream to sustain life for fish and other types of organisms. This disrupts the biodiversity that needs the river system to survive. Excess sediment is not the only issue but also the toxins, like selenium, that is released into the water from the coal. Selenium is a natural element in coal so when the coal is extracted the selenium is released into the ground water. Once in the water this, like the salamander, can cause genetic mutations in the fish and other aquatic life that alters their life span, reproductive systems, and physical traits. This in turn would cause the stream population to drop making it harder for other animals that eat the fish and aquatic life to survive (A. Lemly 09). References Burns, Shirley (2005).

...dairy industry, the goal in minimising the costs of mastitis is always prevention. Proper milking procedures and hygiene, dry cow therapy and quarantining are standard practice on every farm, but is there something extra you could be doing to protect your herd? Supplementation of vitamins and minerals is an excellent way to go that step further in preventing the disease in the first place. Supplements optimise immune function as well as reduce oxidative and metabolic stress, ultimately exerting a positive effect on the udders defense mechanisms against mastitis and the pathogen that cause it. They can be found in a variety of chemically organic and inorganic forms including complexes, proteinates and amino acid chelates. Zinc, Copper and Selenium are the main supplements targeting mastitis. They enhance the antioxidant capacity of superoxide dismutase (CuZnSOD), glutathione peroxidase (GSH-Px) and ceruloplasmin (CP) which are naturally found in the body. These antioxidants outcompete for metabolic resources with damaging superoxide radicals that are produced as part of the immune response to destroy pathogens. These supplements are also very important in the prevention of the disease. Zinc Zinc has many cellular functions that contribute to mastitis protection. It is an antioxidant that also has catalytic, structural and regulatory roles. Zinc supplementation has been shown to decrease SCC during subclinical infection. It is an essential compound for the integrity and barrier function...

...that there must be more comprehensive studies done. Although there was research, it was not comprehensive enough. In the Scott Baker research findings, it was isolated to Japan and a deeper molecular assessment should be done on the whaling industries of the world like Norway in order to globally and accurately determine which species are affected the most. Furthermore, the studies are somewhat outdated and they could benefit from new molecular approaches in order to deepen the research knowledge and make better assessments. For the Tetsuya research findings, there were some weak correlations with the rise of mercury and other elements with the data being largely variable. There was also conclusions drawn that certain elements like Iron & Selenium concentrations increase with age. There could very well be a myriad of reasons as to why there is a high concentration of these elements. The paper even suggests further studies need to be done. Overall, much more research needs to be done on population parameters and health risks associated with...

...having nine hundred micrograms of Vitamin A and with the help of carrots, broccoli, and most fruits I can increase my micrograms. When looking at the RDA for Vitamin E fifteen milligrams is the standard and I was well under that number. Leafy green vegetables such as lettuce, cabbage, or broccoli are all great sources of Vitamin E that I can easily incorporate in to my diet to increase my milligrams. Fit day pointed out my deficiencies as well as my abundances in week one. My selenium levels compared to RDA were considered high almost every day during week one. Not really knowing what selenium was I researched it and found that it is required for thyroid gland to function proper and that it also helps to protect my body from cancers. Taking in too much selenium can cause bad breath, diarrhea, and hair loss. Chicken, turkey, whole grains and Brazil nuts (which happen to be one of my favorite snacks) are good sources of selenium. After reading all of this and having a better understanding of what selenium really is I understood why I had such high statistics compared to the RDA standard. I consume a lot of chicken, brown rice, and fish during my every day diet. My sodium intake each day is more than twice the amount I should be consuming. Going by the RDA standards I should be consuming fifteen hundred milligrams each day and I took in at least four...
