Physiology labs essays Properties of the Isolated Mammalian If we were to compare smooth muscle with skeletal muscle we notice that they are very different from one another. Firstly, smooth muscles have a slow cycling of myosin cross bridges as compared to skeletal muscle. However, the fraction of time that the cross bridges remain attached to the actin filaments is believed to be greatly increased in smooth muscle. Secondly, Less energy is required to sustain the same tension of contraction in smooth muscle as in skeletal muscle. Thirdly, The maximum force of contraction of smooth muscle is often even greater than that of skeletal muscle. This great force of smooth muscle contraction results from the prolonged period of attachment of the myosin cross-bridges to the actin filaments. The Gastrointestinal tract has 2 major networks of nerve fibers - Myenteric plexus and the Submucous plexus. The plexuses are interconnected, and they contain motor neurons that innervate the smooth muscle. This is the enteric nervous system. The intestine also receives a dual extrinsic innervation from the autonomic nervous system, with parasympathetic cholinergic activity generally increasing the activity of intestinal smooth muscle and the sympathetic noradrenergic activity generally decreasing it while causing the sphincters to contract. The GI tract is made up of smooth muscles. The individual smooth muscle fibers are between 200 and 500 micrometers in length and 2 and 10 micrometers in diameter, and they are arranged in bundles of as many as 1000 parallel fibers. In general, smooth muscle can be divided into Visceral smooth muscle and Multi-unit smooth muscle. Visceral smooth muscle occurs in large bundles. Within each bundle, the muscle fibers are electrically connected with one another through large numbers of gap junctions that allow low-resistance movement of ions from one cell to the next. Each layer functions as a syncytium; that is, when an action potenti...

A critical discussion of Porters view that the economic structure of Essay

A critical discussion of Porters view that the economic structure of the restaurant industry determines the pattern of competition in that industry - Essay Example The global restaurant industry is highly saturated and in a mature stage of development along the industry life cycle, a factor that is driven by the economics of the industry. The economic structure is influenced by the tangibles along the value chain for food services organisations, including the volume of suppliers along the supply chain and the pricing structure of procurement, which impacts all restaurant organisations. The industry is also impacted by the demographics of the consuming public in terms of income as well as the availability of financial capital or ability to raise capital in the regions where the food services organisations operate. Hence, there are a variety of factors that will determine the methods and strategies by which competitors attempt to compete to attain some form of competitive advantage that are all linked with the economics of the industry. The restaurant industry In China, as one example, there is a high concentration of Western fast food companies that have saturated the industry. Growth in consumer demand for Western food brands has given food service companies ample opportunities for expansion out of the North American and European markets. However, it not only consumer demand that has provided these opportunities, it is the investment by a more liberal Chinese government that has stabilised the regional economy that provides advantages for market entry and expansion. The government has injected considerable financial capital into urban development, there is more interest by venture capitalists for this same pursuit, and government policies have provided much more incentives for foreign direct investment in the country (Areddy 2009). Inflation has been largely stabilised by government intervention and policy development, thereby offering consumers much more disposable income that is crucial for sustaining profitability. In 2012, the government invested 57.92 billion USD to motivate more effective corporate borrowing and to control interest rates (Safe Trading 2013). From a social perspective, as Chinese culture begins adopting more ideologies and principles associated with a capitalistic economy, lifestyle preferences are changing that are favourable for new entrants in the fast food industry. In contemporary China, 50 percent of consumers prefer eating in restaurants over that of household consumption (Ganster 2006), which provides a potential market of approximately one half billion consumers. In 2008, consumers in Shanghai spent approximately seven percent of their total disposable income on restaurant dining which represented a whopping 20 percent increase in spending from that of 2007 (Rentz and Xu 2010). Therefore, the economic structure of the industry, coupled with higher guarantees of consumer expenditures on food services, establishes an industry environment that can satisfy profit expectations for a variety of major competitors and new market entrants into the country. The entire fast food industry in China, from a market value perspective, increased 16 percent between 2010 and 2011 and is estimated to be worth 74.8 billion USD in revenues to all competitors (Ho 2011). Therefore, major fast food companies, such as KFC, McDonald’s, Pizza Hut and Taco Bell, have found considerable profit success by entering the Chinese fast food market. Prior to recent years, however, in order for the aforementioned companies (and their large variety of other competitors) to achieve market success, they were forced to import food products from the West which significantly raised operating

Case study 2 - Essay Example This paper will describe the approach to care that is necessary to be given to Mr. P and the treatment plan. The paper will also describe the methods for providing both the patient and family members with education. In order to give the proper care needed for any sickness, the care provider should first seek the doctors’ guidance. Since Mr. P is suffering from heart failure, it would be necessary that a follow up is made to ensure that he uses the prescribed drug as required without missing a single prescription. The care will also involve ensuring that Mr. P visits the hospital at the right time. It is also essential that care should involve provision of moral support. In this case, he should be provided with all assistance needed, especially with activities that he cannot do due to his condition (Maron, 2008). The treatment plan of cardiomyopathy and heart failure is to cope with the disease symptoms and signs. It also involves ensuring that the condition is not left to worsen and risks and complications are minimized. The recommended treatments for Mr. P regarding his health status include the use of angiotensin-converting enzyme (ACE) inhibitors. This enzyme assists in boosting heart pumping aptitude. The enzymes include lisinopril, enalapril, captopril, and ramipril. In case he is not able to take ACE, he should be given angiostensin recerpter blockers such as valsartan and losartan. This should be taken in accordance with doctor’s prescriptions. Cardiomyopathy can also be treated using Digoxin (lanoxin) drug. This drug helps in increasing the strength of the patient’s heart muscle contraction. The drug is also said to slow down rate of heartbeat. It minimizes symptoms of heart failure thereby improving the patient’s ability to live with the disease (Maron, 2008). Since Mr. P has some traces of blood fluid in his lungs, it would be necessary that he be given Diuretics water pills that make the patient urinate

Power of Symbols and Symbolism in Nathaniel Hawthornes The Scarlet Let

The Power of the Symbol in The Scarlet Letter All classic literature uses symbolism in one way or another. Nathaniel Hawthorne's Scarlet Letter is no different. The very basis of every character, their personal appearance and way they act revolves around one thing, the Scarlet Letter. The scarlet letter is an "A", in crimson fabric, worn by a Puritan woman for her act of adultery. Its very existence is solely to cause shame and remorse on Hester Prynne and her daughter Pearl, who was conceived in her lust, but it comes to stand for so much more. All of Hawthorne's main characters; Hester Prynne, Pearl, Reverend Dimmesdale, and Roger Chillingworth, feel the wrath of one piece of cloth and learn how character can be created or destroyed by the simplest things. Hester Prynne is the cause for all of a Puritan woman with more than her weight to bear. She was sent to America by her husband, Roger Chillingworth, where she committed adultery with her Reverend Dimmesdale and conceived a child, Pearl. In the beginning of the book, her beauty shines through the plain appearance of Puritan women. "The young woman was tall, with a figure of perfect elegance on a large scale. She had dark and abundant hair, so glossy that it threw off the sunshine with a gleam, and a face which, besides being beautiful from regularity of feature and richness of complexion, had the impressiveness belonging to a marked brown and deep black eyes. She was lady like, too, after the manner of the feminine gentility of those days; characterized by a certain state and dignity, rather than which is now recognized as this indication."(55). But, with her sin, comes the dreaded Scarlet A. The letter, which she so beautifully embroidered, se... ...aders with knowledge and a lifelong lesson. The Scarlet Letter teaches everyone to be able to see the sin and actual insides of someone's soul. After uncovering their deep, dark secrets, one is taught not to judge or persecute the person because of what their heart contains, for their heart may be cleaner than one's own.

The word industry broadly refers to any form of economic activity. Most countries in this world, they have their own industries Just in different types. There are four types of industries such as primary, secondary, tertiary and quaternary industries. Moreover, in order to develop economic in each countries, the government in those countries play an important role in deciding on the types of industries suitable for its economy, their location and the growth of these industries.First, the government have to think about the types of industries in their country because it depends on their physical factors. For example, Cambodia country, its lands are good for agriculture, so the government try to encourage people to do more on this type of industry. As we can know that Cambodia good at growing crops, it means that we can export our production to other countries to develop our economic well. One more thing is that, there are many tourism site in here, so the government try to advertise a nd protect about those places to get more tourist to visit.It means that we can also get benefit from this industry as well. Moreover, for other countries, theirs lands are not quite well about agriculture, but they have natural resources, so they focus more on how to use their natural resources usefully into their Industry. Second, about the location of each industries, there are many points to think about such as energy, raw material, and human resource. Before all industries should be built. For energy, it refers to the power needed to run machines such as computers, equipment for operation, lighting, and so on, so If that location has no electricity, how can those industries work.Furthermore, about law material, If the industries are far from the raw material resources, the owner of those Industries have to spend much money to Import them from somewhere and It takes long time to transport them to the industry.

English Paper Rhetorical Analysis of Frankenstein

Mary Shelley makes us question who really the â€Å"monster† is. Is it the creature or Victor? While the creature does commit murder, he does not understand the consequences of his actions. He is like an infant who is unfortunately left to learn about the workings of society, and his place in it, on his own. He has no companions and feels a great sense of loneliness and abandonment. The creature voices his frustration and anger and seems to try to project his feelings of guilt onto Victor, as if to show him that he is the ultimate cause of the creature’s misery while he is simply the victim of Victor’s manic impulse. Shelley utilizes words, phrases, and specific tones when the creature vents his misery to Victor and this evokes, amongst the†¦show more content†¦While Victor is looked upon to be a normal man while the creature is seen as a monster specifically because of his physical appearance. At eight feet, with a gigantic body and a disfigured face, s ociety only looks upon the creature with fear and disgust. However, I wonder, couldn’t Victor be a monster as well? He abandoned the creature in the horror of the moment and even attempts to take the creature’s life at one point. To me, the creature’s feelings of rage, revenge, and hurt are what any â€Å"normal† human would have felt if left to fend for themselves on their own, with no experience of love or kindness from anyone. I believe that the novel Frankenstein questions several social conventions and norms of society, especially when it comes to our notions of humanity and monstrosity. What makes a monster? What makes a human? This leads to the question of whether we are really humans or monsters. Humanity tends to place a large emphasis on appearance and those who do not fit into this category of the â€Å"ideal or typical physical appearance† are unfortunately more likely to be looked upon unfavorably. While we say to not judge a book by its cover we, in fact, do so, on a regular basis. The media plays a major role in influencing our perspective in terms of the fine line between humanity and monstrosity.
