Stiff Pen Shell (Atrina rigida)
Stiff Pen Shell (Atrina rigida) The stiff pen shell, or rigid pen shell, is one of the several species of pen shells. These mollusks have a long, triangular, or wedge-shaped shell and attach to rocks or shells in sandy, shallow ocean bottoms. Description Stiff pen shells can be up to 12 long and 6.5 wide. They are a brown or purplish-brown color and have 15 or more radiating ribs that fan out across the shell. They may also have erect, tubular spines. Pen shells may produce black pearls. Classification Kingdom: AnimaliaPhylum: MolluscaClass: BivalviaOrder: PterioidaFamily: PinnidaeGenus: AtrinaSpecies: rigida Habitat and Distribution Stiff pen shells live in warmer water from North Carolina to Florida, and also in the Bahamas and West Indies. They are found on sandy bottoms in shallow water. They attach with their byssal threads, pointed end down. Feeding Pen shells are filter feeders and eat small particles passing through the water. Conservation and Human Uses Pen shells have a scallop-like adductor muscle (the muscle that opens and closes the shells) and are edible. They also produce black pearls which may be used in jewelry. Pen shells in the Mediterranean (Mediterranean pen shells) were harvested for their byssal threads, which were woven into an expensive cloth. Sources Gofas, S. 2011. Pinnidae.

Answer questions - Essay Example Therefore, the formation of the family aimed at exposing the members into different sexual orientation in, a more or less, observational technique to understand what sexuality entails. In this case, the family assists in understanding lesbianism and heterosexuals in a detailed manner. The family is not only a study association but also a social bond enhanced by the sexual diversity, indifference and respect. For this reason, the actual meaning of the relationship is immeasurable in both the neither qualitative nor quantitative terms. However, the solidarity and cohesion promoted by the family is unpredictable. The family is an opportunity to understand sexual orientation in a holistic perspective by examining the factors that influence sexuality, social perception, and the challenges experienced by the LGBTQ individuals. The most common type of gender identity microaggressions in an institution is the disapproval of the LGBTQ experience where these individuals receive awkward and condemned treatment. Specifically, the disapproval occurs either consciously or unintentional. However, both cases causes harm to the victim (Nadal 91). Additionally, there is a general perception of the LGBTQs as abnormal for their non-conforming sexual orientation. Specifically, heterosexual individuals consider the LGBTQ persons as overly sexual and sexual deviant (Nadal 93). Other forms of microaggressions include the denial of the reality of transphobia, physical threat and harassment, and denial of bodily privacy among others (Nadal 96). Notably, institutions such as schools and the workplace exhibit instances of gender identity microaggressions. Specifically, the most common types of discrimination occur among friends, family members or even the LGBT people (Nadal, 2013). The consequence of microaggressions includes victimization, suicidal thoughts, substance abuse, and depression among other well-being effects.

Business Policy and Strategic Management - Essay Example It is a discount store outlet, focused on marketing brand names for lower prices. Similar stores such as Woolco and Kmart were not as successful as WalMart, because the latter had some unique operating principles which worked to its benefit. After four decades of operation, Woolco outlets have disappeared, while Kmart has moved into bankruptcy, so that WalMart is the top ranking store in the United States. In international locations, Walmart attracted customers by its Everyday Low Prices. It maintained a relentless cost control system by allowing few perks for its officers and employees. It was also able to negotiate tough deals with its suppliers, using its ability to place bulk orders to also make other demand such as high quality and low prices, which it then passed on to its customers. It maintained several distribution outlets and initiated an electronic data interchange system, allowing suppliers to track sales to deliver new stocks and they were also able to exchange invoices, purchase orders and other documents electronically. Another important aspect contributing to Walmart’s success is its human resource and motivational policies.

Rise of Two Operas Essay Example for Free
Rise of Two Operas Essay The Italians and the French have been two prominent figures in the world of opera music. Their music in the field of tragedy has been flourished by history and emerged from different social context and background. Opera traced its roots from Italy. Opera, in its earliest form can be traced from various types of Italian literature. The themes, moods, and subjects of opera can be associated with Italian poetry, drama, and allegory (Kimbell, 1991. p. 19-21). More importantly, opera particularly the opera seria, has originated at the height of the Renaissance period. The Renaissance art were centered on man. It revolved around man’s greatness, man as passionate, and as virtuous. The themes of opera described the life of the Italians as a whole, which is according to Luigi Barzini: The pleasure of Italy comes from living in a world made by man, for man and on man’s measurement (cited in p. 3). A theme deeply embedded in reality. Revolving around this theme, opera became for the sole purpose of entertainment. However as Renaissance became a period for the flow of rising ideologies, the face of opera changed into a moving art combined with philosophy and moral teaching. This aim served the purpose of educating its audience and not just by mere entertainment (Kimbell, 1991. p. 182). It was Apostolo Zeno and Silvio Stampiglia who created operas that were historical in nature. Stampiglia wrote a series of operas relating early Italian history and Zeno’s works have long been distinguished as a combination of moral and scholarship significance (p. 183). The Italian opera seria had not been completely tragic but became more serious. Metastasio offered ‘suspense’ or in Italian ‘sospensione’ in place of tragedy, in which the audience were presented the internal conflicts of the protagonist. Seeing this kind of progression, the French opera scene has its trend going on as well. However, as mentioned from the beginning, opera had its roots originating from Italy. There were no French composers at that time. It was an Italian national who moved to France, named Jean-Baptiste Lully who was said to have popularized opera to the French people (Edwards, 1862. . 14). Origins of French opera may have come from other form of arts such as ballet. Ballet has incorporated music with dramatic dance routines thus making as a basis into recreating a dance that has dramatic dialogues in the form of music (Grouts Williams, 2003. p. 22). Lully gained full monopoly when spreading his music due to his friendship with King Louis XIV. He collaborated with the likes of Quinault to create operas which they called tragedie en musique (Anderson, 2003. p. 3). It is important to note that though it was the time of Rennaisance in Italy, it had been a slow progress for France to grasp the music from other countries. Since Lully gained monopoly for production of operas, the monarchy controlled the flow of music from outside in accordance to Lully’s advice (p. 1). Basing it from here, the themes of the operas that were being played within King Louis XIV’s court still centered on mythical themes rather than on humanism. The plot of tragedy focused on mythical characters and fictional conflicts (Easterling, 1997. p. 136).

Diabetes Mellitus Essay -- Health Diseases Diabetes Essays medical
Diabetes Mellitus Diabetes is the seventh leading cause of death listed in the United States. Diabetes is the leading cause of blindness. â€Å"In 1996 diabetes contributed to more than 162,000 deaths†(Lewis 1367).      â€Å"Diabetes mellitus is not a single disease but a group of disorders with glucose intolerance in common†(McCance 674). Diabetes mellitus is a metabolic disorder characterized by hyperglycemia (increased blood sugar) and results from defective insulin production, secretion, and utilization. There are many forms of diabetes. â€Å"Diabetes increases the risk of heart and blood vessel disease, amputation, infections, kidney damage, eye problems (including blindness), and nerve malfunction†(Husain). I will briefly define the different forms of diabetes and then I will discuss diabetes mellitus in general. 1.     Insulin dependent diabetes mellitus (IDDM) or type 1 is when the pancreas will produce little or no insulin, therefore requiring injections of insulin to control diabetes and prevent ketoacidosis. All patients with this type of diabetes need insulin to survive (Deakins 34). Five to ten percent of all diabetic patients have IDDM. Usual presentation is rapid with classical symptoms of polydipsia (increased thirst), polyphagia (increased hunger), polyuria (increased urination), and weight loss. IDDM is most commonly seen in patients under thirty, but can be seen in older adults. 2.     Non-insulin dependent diabetes mellitus (NIDDM) or type 2 is caused by a defect in insulin manufacture and release from the beta cell or insulin resistance in the peripheral tissues. Approximately ninety percent of diabetic patients have NIDDM. Genetics play a big role in the etiology of NIDDM and is often associated with obesity. Usually presentation is slow and often insidious with symptoms of fatigue, weight gain, poor wound healing, and recurrent infection. Primarily occurs in adults over thirty. 3.     Gestational diabetes mellitus (GDM) is defined as carbohydrate intolerance, which occurs during pregnancy. Occurs in approximately three percent of pregnancies, and usually disappears after pregnancy. Women with GDM are at higher risk for having diabetes in the future. GDM is associated with increased risk of morbidity. Women should be screened for GDM between the 24th and the 28th weeks of gestation. 4.     Diabetic ketoacidosis is a serious... ...ur to six hours to reach the bloodstream, but stays in the bloodstream for about thirty-six hours. It peaks about fourteen to twenty-four hours after injection. Diabetes affects the entire body. It slowly deteriorates every one of the body’s organs.
