buy custom The Use of Steroids essay Steroids, which may also be termed as the anabolic androgenic steroids bears reference to the hormone testosterone of the male that, are meant for the building of the muscles, enhancement of the performance as well as the improvement of the physical appearance. The anabolic as well as the muscle effect that are associated with the drug are resourceful to the retention of protein in the body of the user. This is a building block that is essential for the development of the body muscles, the skin as well as the bones. The androgenic, also referred to as the muscular effects associated with the drug is a cause of the progression of the males deep voice, the muscle hair, aggressiveness and the facial as well as the body hair. It is however notable that the people who are involved in the abuse of the drug are at a high risk of a wide range of the side effects that are usually unwanted. Most of the unwanted risks are also associated with irreversibility. In the case of the use of injection as a method of application of the drug in to the body there is a high possibility of infection with HIV (Wright Cowart, 1994). The use of steroids in todays society is an issue that is rampart. The stories that are related to the use of steroids have been at the focal point in the media. Their use is commonly reported in most of the professionals taking part ion the baseball players, the cyclists as well as the track stars. These are the most commonly reported cases and some of them have even admitted publicly about their use of steroids in an attempt of achieving an edge in as far as their competitiveness is concerned. The use of the steroids among the athletes is a possible cause of their exclusion from the activities of sport at the time that they are discovered (Wright Cowart, 1994). The problem is specifically serious wih the young people who in most of the situations are exposed to the habit by the members of their peer. The most influential peers are the friend, the acquaintances and the partners in gym. The teenagers in addition to the young adults especially the males who take part in activities such as athletics are particularly exposed to the risks that are associated with the use as well as the abuse of steroids. This is based on they believe that they hold to the effect that steroids contribute in the enhancement of their performance especially during the physical activities ion addition to their general appearance. It is however ironical that the young people are especially exposed to the risks that contribute to significant harm in as far as their bodies are concerned (Wright Cowart, 1994). As an irony, the teens expose themselves to a situation of risk in relation to causing substantial harm in as far as their health is concerned. This is also accompanied with an irreversible situation of a transformation of their appearance in a manner that they may least anticipate. The effects are epitomized in acne, a growth that is stunted, and the assumption of the characteristics of female in young male accompanied by the characteristics of male in young girls. The extent of the research that has so far been conducted reveals the fact that the earlier the onset of the use of the drug, the higher iss the likelihood of indulgence in the experimentations with other drugs of similar kind. The use of steroids is either in an oral form in the form of tablets or even the use of intramuscular injections. The use of the steroids is in most of the cases based on hearsay as well as gossip with respect to the determination of the most appropriate dosage that is associated with an appreciable extent of safety. In the case of the abuse of the drug, the victim usually use to the extent of using a great number of milligramss of the dose on a daily basis who is consequently not a safe level. The actual prescription of the doctor is in the extent of as little as 1 5 milligram on a daily basis in the case that the use of the drug is legitimate. Some untrue assumptions however arises to the effect that the use of high levels of the drug is consequential to some results that are favorable. This therefore leads to the use of a combination of the drug by the users which results to the phenomena that is identified as the stacking. The use of the drug in such cases is usually based on cy cles in which case the drug is commonly used for a period of up to 6 extending to 12 weeks with a time punctuation of refraining from the use of the drug (Wright Cowart, 1994). This is done for the purpose of the avoidance of a situation of building tolerance. There are various degrees of problems that are associated with the use of steroids. Most of the adolescents are usually at high risk in as far as the behavior is concerned. There is a high possibility that they may loose some interests on the activities on daily basis in addition to incidences of energy loss as well as boredom. They are also in a position of experiencing some difficult times in the course of the limitation of the use of the drug. They are also prone to develop some tolerance to the use of steroids calling for the use of huge amounts of the drug in order to achieve the effects that are associated with muscle building. They are also likely to develop some problems that are associated with work in addition to the relationships with other people. The use of steroids is also a possible cause of the phenomena that is identified as the male anorexia in which case the victims are exposed to an experience of dissatisfaction in as far as their image of the body is concerned an d fail to notice the changes that evident in the rest of the people (Wright Cowart, 1994).

The Origins of the Domesticated Grapevine

The Origins of the Domesticated Grapevine Domesticated grapevine (Vitis vinifera, sometimes called V. sativa) was one of the most important fruit species in the classic Mediterranean world, and it is the most important economic fruit species in the modern world today. As in the ancient past, sun-loving grapevines are today cultivated to produce fruits, which are eaten fresh (as table grapes) or dried (as raisins), and, most especially, to make wine, a drink of great economic, cultural, and symbolic value. The Vitis family consists of about 60 inter-fertile species that exist almost exclusively in the Northern Hemisphere: of those, V. vinifera is the only one extensively used in the global wine industry. Approximately 10,000 cultivars of V. vinifera exist today, although the market for wine production is dominated by only a handful of them. Cultivars are typically classified according to whether they produce wine grapes, table grapes, or raisins. Domestication History Most evidence indicates that V. vinifera was domesticated in Neolithic southwest Asia between ~6000–8000 years ago, from its wild ancestor V. vinifera spp. sylvestris, sometimes referred to as V. sylvestris. V. sylvestris, while quite rare in some locations, currently ranges between the Atlantic coast of Europe and the Himalayas. A second possible center of domestication is in Italy and the western Mediterranean, but so far the evidence for that is not conclusive. DNA studies suggest that one reason for the lack of clarity is the frequent occurrence in the past of purposeful or accidental cross-breeding of domestic and wild grapes. The earliest evidence for wine production- in the form of chemical residues inside pots- is from Iran at Hajji Firuz Tepe in the northern Zagros mountains about 7400–7000 BP. Shulaveri-Gora in Georgia had residues dated to the 6th millennium BC. Seeds from what are believed to be domesticated grapes have been found in Areni Cave in southeastern Armenia, about 6000 BP, and Dikili Tash from northern Greece, 4450–4000 BCE. DNA from grape pips thought to be domesticated was recovered from Grotta della Serratura in southern Italy from levels dated to 4300–4000 cal BCE. In Sardinia, the earliest dated fragments come from the Late Bronze Age levels of the Nuragic culture settlement of Sa Osa, 1286–1115 cal BCE. Diffusion By about 5,000 years ago, grapevines were traded out to the western margin of the Fertile Crescent, the Jordan Valley, and Egypt. From there, the grape was spread throughout the Mediterranean basin by various Bronze Age and Classical societies. Recent genetic investigations suggest that at this distribution point, the domestic V. vinifera was crossed with local wild plants in the Mediterranean. According to the 1st century BCE Chinese historical record Shi Ji, grapevines found their way into East Asia in the late 2nd century BCE, when General Qian Zhang returned from the Fergana Basin of Uzbekistan between 138–119 BCE. Grapes were later brought to Changan (now Xian city) via the Silk Road. Archaeological evidence from the steppe society Yanghai Tombs indicates, however, that grapes were grown in the Turpan Basin (at the western edge of what is today China) by at least 300 BCE. The founding of Marseille (Massalia) about 600 BCE is thought to have been connected with grape cultivation, suggested by the presence of a large number of wine amphorae from its early days. There, Iron Age Celtic people bought large quantities of wine for feasting; but overall viticulture was slow-growing until, according to Pliny, retired members of the Roman legion moved to the Narbonnaisse region of France at the end of the 1st century BCE. These old soldiers grew grapes and mass-produced wine for their working colleagues and the urban lower classes. Differences Between Wild and Domestic Grapes The main difference between wild and domestic forms of grape is the wild forms ability to cross-pollinate: wild V. vinifera can self-pollinate, while domestic forms cannot, which allows farmers to control a plants genetic characteristics. The domestication process increased the size of bunches and berries, and the berrys sugar content as well. The end result was greater yields, more regular production, and better fermentation. Other elements, such as larger flowers and a wide range of berry colors- particularly white grapes- are believed to have been bred into the grape later in the Mediterranean region. None of these characteristics are identifiable archaeologically, of course: for that, we must rely on changes in grape seed (pips) size and shape and genetics. In general, wild grapes bear roundish pips with short stalks, while domestic varieties are more elongated, with long stalks. Researchers believe the change results from the fact that larger grapes have larger, more elongated pips. Some scholars suggest that when pip shape varies within a single context, that probably indicates viticulture in process. However, in general, using shape, size, and form is only successful if the seeds were not deformed by carbonization, water-logging, or mineralization. All of those processes are what allows grape pits to survive in archaeological contexts. Some computer visualization techniques have been used to examine pip shape, techniques which hold promise to resolve this issue. DNA Investigations and Specific Wines So far, DNA analysis doesnt really help either. It supports the existence of one and possibly two original domestication events, but so many deliberate crossings since then have blurred researchers ability to identify the origins. What does seem apparent is that cultivars were shared across wide distances, along with multiple events of vegetative propagation of specific genotypes throughout the wine-making world. Speculation is rampant in the non-scientific world about the origins of specific wines: but so far scientific support of those suggestions is rare. A few that are supported include the Mission cultivar in South America, which was introduced into South America by Spanish missionaries as seeds. Chardonnay is likely to have been the result of a medieval-period cross between Pinot Noir and Gouais Blanc that took place in Croatia. The Pinot name dates to the 14th century and might have been present as early as the Roman Empire. And Syrah/Shiraz, despite its name suggesting an Eastern origination, arose from French vineyards; as did Cabernet Sauvignon. Sources Bouby, Laurent, et al.
