Fiber plays an important role in your body’s health by helping to reduce blood cholesterol levels, reducing risk for cardiovascular disease, controlling weight by making you feel full with fewer calories, and helping to prevent constipation. Dietary fibers are fibers that are made up of plant parts that the body cannot digest. The best forms of dietary fibers are found in whole grain foods instead of food made from refined grains. Fiber is found in two forms, soluble fiber and insoluble fiber and each carries its own health benefits (American Heart Association (AHA), 2012).

Soluble fiber is fiber dissolves in water and forms a gel in your stomach delaying the stomach emptying which keeps you feeling full longer. Since it soluble fiber keeps you feeling fuller longer, it can help keep your weight under control. Delayed stomach emptying has an effect on blood sugar levels which can help control diabetes. This fiber can also help lower the bad cholesterol (LDL) by blocking some absorption of dietary cholesterol. Insoluble fiber does not dissolve in water and is considered a gut-healthy fiber. It can have a laxative effect and add bulk to your diet and help prevent constipation (WebMd, 2012). This fiber can reduce cardiovascular risk and slow the progression of cardiovascular disease in those considered high-risk. Some examples of soluble fibers foods are oat bran, peas, rice bran, beans, citrus fruits, strawberries, and apple pulp. However, oats have the highest proportion of soluble fiber over any other grain. Some examples of insoluble fiber foods are whole-wheat breads, wheat bran, wheat cereals, rice, rye, barley, beets, cauliflower, carrots, and turnips (AHA, 2012).

Dietary fiber intake amounts vary among adults and children. It is recommended that children age two and over begin eating a diet that contains no more than seven percent of their calories in saturated fat, no more than one percent of their calories in trans-fat, and no more than 300 milligrams a day in-taking cholesterol. Both adults and children should take in 14 grams of fiber per 1000 calories taken in. An adult on a 2000 calorie diet should around six to eight servings of grains at which half of those servings should be in whole-grain form as well as eight to 10 servings of vegetables and fruits. It is recommended that adults take in 25 grams of fiber a day (AHA, 2012).

Use your textbook or Internet research to support your answer. The Physical layer is something simple like wiring, fiber and network cards. Devices that allow communication between the OSI networks. Data link layer is the Ethernet, among other protocols; we're keeping this simple remember. The most important take-away from layer 2 is that you should understand what a bridge is. Switches, as they're called nowadays, are bridges. Network layer is an IP address because you're dealing with layer 3 and "packets" instead of layer 2's "frames." IP is part of layer 3, along with some routing protocols, and ARP (Address Resolution Protocol). Transport layer handles messaging units which is also called packets. When you're talking about specific protocols, like TCP, they're "segments" or "datagrams" in UDP. This layer is responsible for getting the entire message to keep track of fragmentation. Session layer is Network Basic Input/output System model allowing applications on separate computers to communicate over a local area network. The Point-to-Point Tunneling Protocol (PPTP) is a method for implementing virtual private networks. PPTP uses a control channel over TCP and a GRE tunnel operating to encapsulate PPP packets.

Electrical Stimulation

...in the body (the other two being cardiac and smooth muscles) that allows movement by contraction of the muscles. When a motor unit, a single nerve that innervates all the muscle fibers, activates these muscles fiber, it causes a muscle contraction. These muscle contraction occurs when motor neurons from the spinal cord leaves and activates multiple muscle fibers, the number of muscle fibers depend on the type of muscle. According to the Hennemen size principle, muscles that react rapidly and exert fine control have smaller motor units than those with larger, weight-involving muscles, whose movements are less precise, will require larger motor units. The means of movement and force generation is based on the skeletal muscles contraction. Contractile units of the skeletal muscles include thick myosin and thin actin myofillaments or fillaments. Sarcomere is the smallest contractile unit of a muscle fiber. The repetition of the sarcomere structure make up myofibrils and hundreds to thousands of these myofibrils make up a single muscle fiber (Sherwood 258). Contraction is initiated by an increased in the intracellular calcium concentration which triggers an action potential in the plasma membrane by the depolarization of voltage gated calcium channels. When the muscles contract, the skeletal muscle fibers actively shortens, the thin filaments are propelled toward the center of their sarcomere by movements of the myosin cross-bridges that bind to actin (Sherwood 271). In the first...

Niche Market

...Nancy Cassill and Dr. William Oxenham). The purpose of this research was to analyze how a niche strategy can be used by US textile and apparel companies to compete with lower priced imports. With the increasing globalization of the industry, it has been suggested that companies focus on products that offer a competitive advantage over commodity products (Standard and Poor’s, 2003). One way of doing this is to focus on specialized, or niche, products. The conceptual models used in this study provided a framework for specialization within trade. The trade theories examined were 1) Ricardo’s Comparative Advantage Theory (Ricardo, 1817), 2) Heckscher-Ohlin Trade Theory of Factor Proportions (Heckscher & Ohlin, 1991), 3) Posner’s Technology Trade Gap Theory (Posner, 1961), 4) Vernon’s Theory of the Product Life Cycle of Trade (Vernon, 1966), and 5) Porter’s Model of Competitive Advantage (Porter, 1998). Each of these trade theories predicts specialization as a result of trade. This means that as trade barriers decrease, a country’s resources will focus on those processes in which it has a competitive advantage. For the US textile and apparel industry, this means moving away from basic textile items used in apparel production, such as basic fabrics, and moving towards more focused and specialty products, which includes niche products. The methodology used in this study consisted of two phases. Phase I used a deductive research design with an aim to clarify niche strategy issues and provide...

Types of Chromatography

...Types of Chromatography Adsorption Chromatography Adsorption chromatography is probably one of the oldest types of chromatography around. It utilizes a mobile liquid or gaseous phase that is adsorbed onto the surface of a stationary solid phase. The equilibriation between the mobile and stationary phase accounts for the separation of different solutes. Partition Chromatography This form of chromatography is based on a thin film formed on the surface of a solid support by a liquid stationary phase. Solute equilibriates between the mobile phase and the stationary liquid. Ion Exchange Chromatography In this type of chromatography, the use of a resin (the stationary solid phase) is used to covalently attach anions or cations onto it. Solute ions of the opposite charge in the mobile liquid phase are attracted to the resin by electrostatic forces. Molecular Exclusion Chromatography Also known as gel permeation or gel filtration, this type of chromatography lacks an attractive interaction between the stationary phase and solute. The liquid or gaseous phase passes through a porous gel which separates the molecules according to its size. The pores are normally small and exclude the larger solute molecules, but allows smaller molecules to enter the gel, causing them to flow through a larger volume. This causes the larger molecules to pass through the column at a faster rate than the smaller ones. Affinity Chromatography This is the most selective type of chromatography employed...

ANS: Message length = M bytes Header length = H bytes Protocol layers = n Header bytes per packet = aH Total bytes per packet = M+aH Fraction of bandwidth filled with header= aH / ( M+aH) If the packets were fragmented it would result in a larger fraction of the bandwidth filled with header information since fragments would have to replicate header information. So this extra header information would increase message overhead. Q2.

Marketing Mix

...The Marketing Mix  There are many items or situations that require a well-balanced mixture in order to be successful. For instance, a cake mix requires a specified amount of each item, otherwise the cake might be too sweet or just not good at all if the ingredients aren't mixed right. The same is true with marketing. Marketing requires a good mixture in order to be successful in the final sale of the product at a profit. The following will discuss what the marketing mix is and a brief history of the marketing mix. It will also discuss further in detail the four P's of the marketing mix, as well as, show the relation of the marketing mix to a product offered by Verizon Communications.  The History of the Marketing Mix and the Four P's  The term "marketing mix" has been dated to originate sometime in the late 1940's. Neil H. Borden, a teacher at the time, began using the term after James Culliton had described the marketing manager as a "mixer of ingredients". The term "marketing mix" gained its popularity in 1964 when Borden published his article, The Concept of the Marketing Mix. Borden's original marketing mix included product planning, pricing, branding, distribution channels, personal selling, advertising, promotions, packaging, display, servicing, physical handling, and fact finding and analysis. The ingredients of Borden's original marketing mix were later regrouped by E. Jerome McCarthy into what is known today as the 4 P's of marketing: Product, Price, Place, and Promotion...

...Proposal for Use of Pseudostem from Banana Tree (Musa cavendish) D. G. FERIOTTI & A. M. IGUTI Maua Institute of Technology, Sao Caetano do Sul, Brazil (danygf85@yahoo.com.br) ABSTRACT This paper presents a proposal for use of pseudostem from the banana tree (Musa cavendish). After banana harvesting, the pseudostems are cut and left in the fields. In order to add value to banana plantation, the pseudostem could be processed into products. Nowadays, the pseudostem fiber has been used mainly in handicrafts. Although studies have shown that the cellulose fiber has suitable features to industry, the yield is low because pseudostem has about 90% of water. This research presents the physicochemical composition of the liquid fraction extracted from pseudostems and proposes an application for it. The following analyses were performed: sugar, protein, fat, solids, sodium, potassium, calcium, magnesium, chloride, tannin, polyphenoloxidase and peroxidase activity, microbiological and pesticides. Once it contains potassium and sodium, the development of a sport drink seemed suitable. The paper presents some social and economical data of Vale do Ribeira region, the main banana producing region of Sao Paulo State. Additionally, some concepts of the banana plantation are reviewed as well as information about sport drink and the new Brazilian law on athlete’s food. Data about its market are also included, and the results of analyses. The results showed that the liquid fraction...

Led Light

...A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p–n junction diode, which emits light when activated.[4]When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. An LED is often small in area (less than 1 mm2) and integrated optical components may be used to shape its radiation pattern.[5] Appearing as practical electronic components in 1962,[6] the earliest LEDs emitted low-intensity infrared light. Infrared LEDs are still frequently used as transmitting elements in remote-control circuits, such as those in remote controls for a wide variety of consumer electronics. The first visible-light LEDs were also of low intensity, and limited to red. Modern LEDs are available across the visible,ultraviolet, and infrared wavelengths, with very high brightness. Early LEDs were often used as indicator lamps for electronic devices, replacing small incandescent bulbs. They were soon packaged into numeric readouts in the form of seven-segment displays, and were commonly seen in digital clocks. Recent developments in LEDs permit them to be used in environmental and task lighting. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime...
