In 2006 our worldÃ¢â¬â¢s human population was approximately 6. 7 billion. It is projected to increase to 9. 2 billion by 2050. With this many people in the world you need a substantial amount of food to feed them. But, this leads to a problem in the food industry. Animals do not grow fast enough in order to meet these high demands. In order to compensate for the lack of supply of food the farmers need to somehow make their animals grow faster. For the solution they introduced the use of hormones. These hormones include estradiol, progesterone, testosterone, zeranol, trenbolone acetate and melengesterol acestate. Some of these hormones are found naturally in humans and some are synthetic growth promoters. But, is it safe for these foods to be consumed by people; and do they have any effects on our bodies? First, letÃ¢â¬â¢s define the term hormone. Hormones are chemicals that are produced naturally by our bodies and in the bodies of animals. They are released into our blood by the organs that produce them and they travel to different parts of the body. They affect body functions such as growth, development and reproduction. So how are these hormones beneficial to food producers? Well, they improve the meat quality, increase feed efficiency, reduce costs for producers, increase slaughter time and increase animal growth cycles; to name a few. LetÃ¢â¬â¢s take a closer look at the specific hormones used in this industry. Estradiol, in the human body, is a form of estrogen, a female sex hormone produced by the ovaries. Estradiol is used to treat symptoms of menopause, prevention of osteoporosis, replacement of estrogen in women with ovarian failure and sometimes used as a cancer treatment. Progesterone is used to cause menstrual periods in women. It is also used to prevent overgrowth in the lining of the uterus. Testosterone is a sex hormone that is produced in male testicles. It is used to treat conditions in males such as delayed puberty, impotence, or other hormonal imbalances. Is it also used in women to treat breast cancer that has spread to other parts of the body. Zeranol is a potent nonsteroidal growth promoter that mimics many of the effects of estradiol. It is used extensively in the United States and Canada to promote rapid and more efficient growth rates in animals. Trenbolone Acetate is a potent androgen that produces very strong anabolic activity. It is primarily used to buildup muscle mass. Melengestrol acetate is a synthetic progestin used primarily for the suppression of estrus in heifers; it also helps animals to gain weight faster and limit the amount of feed eaten. Yes, all these hormones prove to be beneficial to producers in many ways. But, our society today is focused on eating at fast food restaurants and eating lots of meat products. These hormones used are usually still detectable in the meat that we consume. Now ask yourself; how much meat do you eat in a week? A month? A year? Think about how much of those hormones you are ingesting into your body. Yes, they are at low levels but if you eat these products constantly on a regular basis your body is being exposed to a high amount of these hormones which can alter your body functions. For example, according to the National Toxicology Program at the National Institutes of Health, estradiol and progesterone are considered probable carcinogens. Estrogen has been linked to breast cancer in women and testosterone with prostate cancer in men. Progesterone has been found to increase the growth of ovarian, breast and uterine tumors. Expert D. Lindsey Berkson, author of Hormone Deception, worry that hormones in food could be at least partly responsible for early puberty. The average age for a girlÃ¢â¬â¢s fist period is now between 12. 5 to 12. 9 for Caucasian girls and around 12. 2 for African American girls; which are significantly younger than previous years.

The following paper is about the resumption of whaling by Norway with a focus on the American attitude towards whaling in general. Whaling is a very sensitive issue for many people, including myself. There are many people who feel that whales are highly intelligent mammals, akin to humanity in many ways. They cite the fact that whales mate for life, the size of the average whales brain, and the proof that whales communicate with one another ; all of these traits they share with us. The anti-whaling people feel that to kill whales for their meat or oil, would be like killing people for their meat or oil. The pro whaling people don't buy any of their reasoning. The pro whaling people feel that it is their right to use their resources any way that they want, and no one can tell them what to do. These people don't feel that whales are intelligent or that the size of their brains has any thing to do with it. The people of Norway don't see a problem with whaling because they were raised w ith it. The anti-whali An international study by Milton Freeman and Stephen Kellert, published in 1992, surveyed people in 6 major countries including Australia, Germany, Japan, Norway, The United Kingdom and The United States about their attitudes towards whales and whaling. 57% of the US respondents confirmed that they Ã¢â¬Å"opposed the hunting of whales under any circumstancesÃ¢â¬ and 55% felt that Ã¢â¬Å"even regulated whaling must be abandonedÃ¢â¬ (Skare 1994). Although none of the respondent groups showed a high level of knowledge on the subject, all seemed to agree on the following points. 1. The protection of whale habitats from pollution and disturbance. 2. Maintaining an Ã¢â¬Å"ecosystemÃ¢â¬ perspective in whale management. 3. Basing harvest levels on the most sound scientific advice available. In Norway where whale hunting was once a big industry the proponents of whaling scoff at the prospect of a world without whaling. Norway claims that whaling in their country dates back more than ten thousand years (Skare 1994) and that history, they claim, gives them the right to exploit the resources that they have available to them; what they don't say is that those Ã¢â¬Å"resourcesÃ¢â¬ aren't really their own to exploit. Eric Doyle, a member of Greenpeace, an environmental watchdog group, explained to me (over the telephone) that the boundaries that countries draw up don't mean anything to whales or even to whaling boats in some instances. Doyle, explained that because Norway is one of the very few countries that have resumed whaling ,their boats aren't closely watched, and are often overlooked because there aren't many of them out there (Doyle 1995). Norwegians who are involved in whaling, hunt Minke whales in the northeast Atlantic, where the whale stock is estimated to consist of approximately eighty-six thousand seven hundred minke whales (Donovan 1994). In the late eighties Norway imposed a ban on itself that ended whaling, commercially, whaling for the purpose of scientific research, however continued with no end in sight. The History of The Regulated Whaling IndustryÃ¢â¬ ¦ Whaling has always been a source of income and, whales an endless source of useful products. The meat for our diets, the oil to lubricate our cars and bicycles, the blubber to make shampoo, soap, and many other products too numerous to mention (Skare 1994). However with the invention of synthetic oils and the notion of healthy living on our minds; the average American has little interaction with whale products. This fact has constituted the main body of the anti-whaling argument, as if to say, if the Americans can live without whaling then everyone else can too. In nineteen-twenty six, the League of Nations created a subcommittee to oversee and regulate the growing whaling industry; but it was not until nineteen forty-six that a working regulatory committee was established. At the initiative of the United States, the International Convention for the Regulation of Whaling (ICRW) was adopted by the League of Nations. The ICRW called for such a working committee, and thus the International Whaling Commission (IWC) was created. ICRW was intended to safeguard and regulate whale stocks for future generations, and also to ensure the orderly development of the growing whaling industry. The only catch (pardon the pun) is that the ICWR made it possible for any country to exempt itself from the IWC's rules by simply filing a formal protest and abstaining from voting on referendums brought up at the yearly meetings of the IWC. To no ones surprise, after approving the ICRW, Norway immediately filed a formal complaint and abstained from every vote the IWC held; thereby exempti Ã¢â¬Å"But the matter of substance is, what is the point of having a scientific committee if it's unanimous recommendations on a matter of primary importance are treated with such contempt? Ã¢â¬ Hammond was expressing his frustration and anger with Norway for exempting themselves from the ICRW, and with the IWC for being powerless to enforce any of it's own rulings. Norway went ahead with its plan to whale that year and took 226 whales and an additional 69 for research. In 1993 the catch totaled 369 animals with an unknown number (either additional or included) taken for research, and the 94Ã¢â¬ ² season saw 411 animals with an additional 178 for ,you guessed it, research. Norway continues to whale against the recommendations of the IWC, Greenpeace and every other organization that tracks Cetacean population levels. At the time this paper was created there were no totals for the 1995 season, but if the numbers follow the trend of the past three seasons, the catch is guaranteed to be higher than that of the 1994 season. That could mean the deaths of over 600 minke whales. Regardless of the side one takes, it is becoming evident that some thing must be done before this problem becomes too large to handle. Possible Solutions This debate has gone on for many years and in all likelihood will go on for many more, with no end in sight some solutions must be found in order to reach some kind of settlement or compromise. Some of these solutions might include.

Two Old Women book review - Essay Example Wallis had written the book sensitive based on the aspect of womanhood and nature that had been presented to retain survival within the members. The book is vital to predict the events that lead to the seclusion of selected societal members in an attempt to adjust to the harsh environmental challenges faced within unstable societies. WallisÃ¢â¬â¢ short book had been written to predict the events that had occurred following the decision by a tribe to abandon two elderly women, following a natural calamity that threatened the development of their society. The events had been followed by the decision of the tribe to witness their reduced participation towards healthy development in the tribe. Wallis explains that these women had been linked to complaining instead of providing positive ideology to assist in eliminating the challenges. The book explains the ability of a stable societal system to make the decision to protect sensitive members within the system and encourage hard work through harsh subjections. The elderly women had been alienated despite their condition due to the burden that they would present to the new society. The decision had been made due to the harsh famine that had plagued the land. Despite the decision to abandon the women due to their condition, the result is unexpected because they apply determination and friendship to overcome the challenges. The community had made the decision to abandon the women because they had been considered a setback to the development within the new land that the tribe sought to create. The decision had been made because they had been considered weak and would not last the extreme famine witnessed. However, the twist in the story is realized when the women manage to overcome these challenges and plough through the burden that had been subjected upon them. Ch Ã¢â¬Ëidzigyaak and SaÃ¢â¬â¢ managed to articulate solutions to present survival measures. Through the help of the daughter and her grandson, Ch

Compounds - Assignment Example The shampoo is used for pets and is not used for human needs. The shampoo is used to groom mainly dogs and horses and they are rendered fatal if consumed. This is due to the high iodine content which can cause iodine poisoning when consumed. Another iodine product that is commonly used is Kent Marine Concentrated Iodine used in aquariums. Iodine occurs naturally in plants and in some animals and animal products. Iodine easily attaches to organic compounds and this explains why the main sources include animals and plants. Many plants contain iodine as it occurs naturally on earth and when plants are growing, they absorb it from the soil. Iodine is more concentrated in water bodies as compared to the dry earth (ACP, 1996). For this reason, seaweeds are considered to be the richest in iodine concentration compared to other plants. Examples of such seaweeds include Nori, Hijiki, Dulse, sea lettuce, Kombu, and Wakame and they are all edible. Animals and animal products also contain natural iodine. Examples include sea animals, especially fish and shellfish, especially the ones found in salt water bodies. Milk and eggs are also a rich source of natural iodine. Food fortification technology is a common practice in the food industry. Table salt was among the first products to be iodized and its use is to supplement dietary iodine. Food fortification is aimed at achieving the required dietary intake of any given minerals. It is also aimed at improving the bioavailability of that given mineral by enhancing its absorption in the body. This technology utilizes the ionic form of Iodine (Iodides and Iodates). Iodization of animal products is also done so as to increase the natural source of iodine content in animal products. Iodine is also used in other fields. In the medical fields, radioisotope technology is commonly used in the diagnosis (Eagleson, 1994). This is referred to as nuclear medicine where a radioactive isotope is used to map the extent of the

Visual analysis of The Merode Altarpiece - Essay Example The Merode Altarpiece is a painting by Renaissance artist Robert Campin whose creation time is around 1427 to 1432. The painting was created in Tournai in the Netherlands, which is the artistÃ¢â¬â¢s place of origin but it is currently on display at the Metropolitan Museum in the United States (The Metropolitan Museum of Art). The painting is divided into three panels; the main panel shows the moment just before the annunciation of Mary. She is sitting on the floor reading a bible and is looking down. To her left is an angel she is not aware of, with an oval table separating them. A small figure of Jesus is flying towards Mary holding a crucifix. The right panel has Saint Joseph in a carpentry workshop where he is making mousetraps with a townscape appearing behind him in an open window. The right panel has two figures, assumingly the commissioners of the painting, called the donors waiting to go inside an open door (Barnet, Peter, & Nancy 125). This painting also goes by the name Ã ¢â¬Å"The AnnunciationÃ¢â¬ , which is an event in the Christian Holy Bible in which a virgin by the name of Mary receives the news of her appointment to be the earthly mother of GodÃ¢â¬â¢s son, Jesus.An angel from heaven visits her while she is at home and gives her the good news. The name itself also hints one on the purpose of the painting: Christian believers or cathedrals for devotional and aesthetic purposes commissioned altarpieces. It is therefore a religious artwork. The artist captures the human figures and specifically their faces with their expressions on, making the artwork more of a combination of portraits to make a composition. However, there are outdoor scenes appearing from the openings and windows in the backgrounds depicting cityscapes. The work therefore combines both landscape and portraiture although the portraiture aspect seems to dominate more. According to the Metropolitan Museum, The Merode Altarpiece measures 64.5 cm in length by 117.8 cm as an overall painting with a main panel of dimensions 64.1cm by 63.2 cm, and two identical side panels measuring 64.5cm by 27.3cm each. The width of the painting is slightly below two times the height therefore creating a rectangular (landscape) orientation of the work. The artist employs much use of rectangles, squares, and straight lines in vertical or horizontal movements that harmoniously blend in with the shape of the frame. For instance, in the middle panel where the figures are in a room and the wall and ceiling lines originate from the background and come to meet the frame, creating a view as if one is peering through a window or the wall is missing (Nici 243). The frames merge with most of the shapes rather than disagree with or break them. The Merode Altarpiece is oil on Oakwood. The style of creating workspace and framing is popular as panel art. Panel art is a technique of creating frames in the renaissance period where artists had carpenters make them wooden panels covered with clo th and plastered with gesso paste to create a smooth painting surface (DÃ¢â¬â¢Elia 19). The work is done in oil paints, which is another preference of most renaissance artists. During the renaissance period, the use of tempera colors was becoming unpopular as artists discovered that oil

Strategic Management - Essay Example In order to earn profits on the part of a company, it is deemed very necessary for a company or a business firm to do something different than the rest of the lot so that it is considered as an entity that provides value and meaning to its customers different from the rest of the remaining lot. This value can be in the form of provision of a totally different and novel service that the company might give at a particular period of time or bring in certain activities that mesh along well with the companyÃ¢â¬â¢s varied products which are actually being sold under the umbrella of the companyÃ¢â¬â¢s name. Hence the changing market structure might call for changing strategies and lines of action that would all target the people for whom the product is actually designed as well as the competitors with whom the clutter is being broken in the environs of the marketplace. Thus competition brings in more and more quality at the end of the company with regards to its products as well as more sales in the form of its varied and changed stance on focusing towards the customers rather than the product itself. Apart from that, emphasis on need must be the order of the day rather than bringing out more and more varied stock key units just for the sake of it. The different products should satisfy each and every user rather than satisfy the people sitting in the innovation labs and those who invent just to take the company one step further. This trap should thus be avoided under all circumstances.
