Appendicitis
From Wikipedia, the free encyclopedia |
Appendicitis is a medical emergency characterized by inflammation of the appendix, many cases of which require removal of the inflamed appendix, either by laparotomy or laparoscopy. Untreated, mortality is high, mainly because of the risk of rupture leading to infection and inflammation of the intestinal lining (peritoneum) and eventual sepsis, clinically known as peritonitis which can lead to circulatory shock. Reginald Fitz first described acute and chronic appendicitis in 1886, and it has been recognized as one of the most common causes of severe acute abdominal pain worldwide. A correctly diagnosed non-acute form of appendicitis is known as "rumbling appendicitis". Appendicitis is most common between the ages of 5 and 40; the median age is 28. It tends to affect males, those in lower income groups, and, for unknown reasons, people living in rural areas.
The term "pseudoappendicitis" is used to describe a condition mimicking appendicitis. It can be associated with Yersinia enterocolitica. acute appendicitis appendicitis of acute onset, requiring prompt surgery, and usually marked by pain in the right lower abdominal quadrant, referred rebound tenderness, overlying muscle spasm, and cutaneous hyperesthesia. chronic appendicitis
1. that characterized by fibrotic thickening of the organ wall due to previous acute inflammation.
2. formerly, chronic or recurrent pain in the appendiceal area, without evidence of acute inflammation. fulminating appendicitis that marked by sudden onset and usually death. gangrenous appendicitis that complicated by gangrene of the organ, due to interference of blood supply. obstructive appendicitis a common form with obstruction of the lumen, usually by a fecalith.

Eyesight from Wikipedia

...HELLO THERE The visual system in humans and animals allows individuals to assimilate information from the environment. The act of seeing starts when the lens of the eye focuses an image of its surroundings onto a light-sensitive membrane in the back of the eye, called the retina. The retina is actually part of the brain that is isolated to serve as a transducer for the conversion of patterns of light into neuronal signals. The lens of the eye focuses light on the photoreceptive cells of the retina, which detect the photons of light and respond by producing neural impulses. These signals are processed in a hierarchical fashion by different parts of the brain, from the retina upstream to central ganglia in the brain. Note that up until now much of the above paragraph could apply to octopi, molluscs, worms, insects and things more primitive; anything with a more concentrated nervous system and better eyes than say a jellyfish. However, the following applies to mammals generally and birds (in modified form): The retina in these more complex animals sends fibers (the optic nerve) to the lateral geniculate nucleus, to the primary and secondary visual cortex of the brain. Signals from the retina can also travel directly from the retina to the superior colliculus. The second school advocated the so called 'intro-mission' approach which sees vision as coming from something entering the eyes representative of the object. With its main propagators Aristotle, Galen and their......

Wikipedia Swot

...Wikipedia SWOT Analysis and Competitors Wikipedia has a lot of strengths and a great field of opportunities; can be qualified as a Encyclopedia and as a Wiki, in both categories has competition and could be surpassed by a Chinese version of a free encyclo-pedia; Wikipedia as we will see encounters opportunities that are great but that could be a weakness too, the global nature of Wikipedia can make the community unmanageable and prone to corruption; Wikimedia counts with more than 30 chapters in more that 280 languages ; Wikimedia is part of a global network of individuals, organizations, chapters, clubs and communities and all work together to maintain Wikipedia . Wikipedia has many competitors, many are “dead” but many others are making it’s own way in the knowledge field. Sites like Veropedia and Citizendium were created with the same objectives of globalize and share the knowledge, but with few differences like the information should be enhanced by experts, these models have been less successful. Veropedia was created in October 2007 and shut down in January 2009, their principals were very much like the Nupedia project, the idea was to enhance articles coming from Wik-ipedia and to fill the Veropedia servers with more accurate information, its revenue would come from user donations but at the end the project was supported exclusively by its creators ; as of today the Veropedia project has disappeared and its web page is hosting spam.

Breaking Free from Product Life Cycle

...Breaking Free from the Product Life Cycle Part A. Basic Concepts and Ideas 1. The established product life cycle dictates that after a period of introduction and growth, the product will mature and then gradually decline and lose its market share. There are proposed methods aimed at breaking this rise and decline model which utilized techniques called reverse positioning, breakaway positioning, and stealth positioning. 2. Each positioning technique is generally associated with a certain type of product or firm. The reverse positioning method can be used by companies providing intangible services. The breakaway method can be used by tangible packaged goods. The stealth positioning method can be used on technology based products. 3. Reverse positioning occurs when a service providing firm drastically eliminates the number of features typically offered the customer in the industry. While reducing the number of options given to the customer, the firm introduces new high quality features that serve a niche market. Breakaway positioning involves the re-branding of a product into a new marketplace. No features of the product are eliminated nor introduced. The product is simply marketed toward a new audience. Stealth positioning is a complex strategy of introducing new products to consumers in a non-straightforward manner. In short, consumers buy the product believing it to be used for one purpose, when in practical function, it is used for other purposes. Part B.......

Breaking Free from Product Marketing

...Breaking Free From Product Marketing 2012/2013 May 22 Breaking Free From Product Marketing Analysis Service marketing, to be effective and successful, requires a mirror-opposite view of conventional ''product" practices. Shostack cautions that 'it is wrong to imply that services are just like products 'except' for their intangibility' and further identifies that the language of marketing is in fact derived from the manufacture of physical goods. Services were never previously considered different until the view developed around the work of G. Lynne Shostack[1] who produced an article in 1977 “Breaking Free from Product Marketing”. The article presented the view that services are significantly different from products. It suggested that the practice of marketing of services using the framework developed for tangible products (goods) has limited thinking about services marketing. Until that time, if you wanted to make some differentiation between tangible based products and intangible based products you used the accepted “goods and services”. Breaking Free from Product. Marketing. Service marketing, to be effective and successful, requires a mirror-opposite view of conventional …. Shostack just didn’t understand what a product is.

Is Data Stored in the Cloud Free from Prying Eyes?

...Is data stored in the cloud free from prying eyes? Cloud storage is an internet service that provides storage to computer users. Those who use corporate or private e-mail servers do not store their communications in the cloud environment. Important legal rulings highlight the differences between the two ways for storing e-mail. This an internet service that provides storage to computers users who are online social networking websites were you can upload pictures and store messages in your inbox and profile and those who utilize web based email store their sent and received e-mail messages in the e-mail provider’s cloud environment. That is a very good question well I am sure people store data in different locations because you wouldn’t know when your pc or laptop would crush so for some this might be the reason. For other’s am sure it might be in order to hide something that they are doing behind some ones back and this does not mean they are free because at any time someone else might be able to find the information. I think the idea of computer use is being manipulated by some government systems. People should be careful. Due to the increase in technology most companies store their data in web sites and in the data cloud. Those who have the skill and knowledge store their information in private email servers and do not store their information in the cloud. When you store information in the cloud the law enforcement agencies consider e-mail stored in the cloud to be the......

Monopoly from Wikipedia, the Free Encyclopedia This Article Is About the Economic Term. for the Board Game, See Monopoly (Game). for Other Uses, See Monopoly (Disambiguation). "I Like a Little Competition"—J. P. Morgan

...------------------------------------------------- Monopoly From Wikipedia, the free encyclopedia This article is about the economic term. For the board game, see Monopoly (game). For other uses, seeMonopoly (disambiguation). "I Like a Little Competition"—J. P. Morgan by Art Young. Cartoon relating to the answer J. P. Morgan gave when asked whether he disliked competition at the Pujo Committee.[1] A monopoly (from Greek monos μόνος (alone or single) + polein πωλεῖν (to sell)) exists when a specific person or enterprise is the only supplier of a particular commodity (this contrasts with a monopsony which relates to a single entity's control of a market to purchase a good or service, and with oligopoly which consists of a few entities dominating an industry).[2]Monopolies are thus characterized by a lack of economic competition to produce the good or service and a lack of viable substitute goods.[3] The verb "monopolise" refers to the process by which a company gains the ability to raise prices or exclude competitors. In economics, a monopoly is a single seller. In law, a monopoly is a business entity that has significant market power, that is, the power to charge high prices.[4] Although monopolies may be big businesses, size is not a characteristic of a monopoly. A small business may still have the power to raise prices in a small industry (or market).[4] A monopoly is distinguished from a monopsony, in which there is only one buyer of a product or service; a monopoly......

A term paper is a written original work discussing a topic in detail, usually several typed pages in length and is often due at the end of a semester. There is much overlap between the terms "research paper" and "term paper". The phrase "term paper" was originally used to describe a paper (usually a research based paper) that was due at the end of the "term" - either a semester or quarter, depending on which unit of measure a school used. However, the term has fallen out of favor. Common usage has "term paper" and "research paper" as interchangeable, but this is not completely accurate.

...102 November 2, 2015 Yay or Nay             The mission of Wikipedia was to design it to be used as a free encyclopedia and research tool in which readers could obtain verifiable information.  Wikipedia has been questioned by many individuals concerning its creditability. It is open to a large contributor base allowing anyone to edit and write anything.  Many use information from Wikipedia to do research without second guessing or even thinking that the information being obtained may actually be false.  “Users should be aware that not all articles are of encyclopedic quality from the start; they may contain false or debatable information” (Wikipedia: Using Wikipedia as a research tool).   Determining whether Wikipedia is good or bad as far as being able to be used as a source of credit worthy information is kind of hard to figure out. Believing that the pros of Wikipedia outweighs the cons, it is still hard to find a balance. When you search for something on the internet, the first link to direct your search is a link involving Wikipedia which some would consider a good sign.  Wikipedia is a good source to read when you absolutely have no knowledge about what you are researching. Since entries can be made by anyone, the diversity of different subjects could be beneficial. You could learn how one subject could become many due to the differences in cultural and personal opinions.   “Wikipedia takes information from other reliable websites and puts it onto one portal.  Each......
