buy custom Decision Support Systems Network Flow Models essay

buy custom Decision Support Systems Network Flow Models essay Decision support system enables modeling of data and influencing decision making basing the reason on the data. In many successful businesses, decisions are made after analyzing data in order to suggest strategies and solutions. This is important in that it becomes easy to predict the future performance of the business. Decision support systems (DSS) are computer applications with human as a major component. The systems can analyze large loads of data effectively and guide the human component in making choices. When DSS was introduced in businesses, many thought that the systems belong to certain areas in business. However, nowadays, many businesses have actually incorporated the systems in all aspects of their operations; for instance, the systems have been applied in the budget sheets, data concerning sales, and in forecasts such as in projects. Network flow models are an example of a DSS; the ability to predict the success or failure of programs by using the arcs and the nodes is an interesting aspect of the network model. For instance, in case of project management, some of the key procedures include evaluation of the program and review of techniques used. The use of network model enables determination of success of the project. To determine this, the project is represented as a network flow models and by using node interdependency, it becomes easy to predict the performance of the project. The network model provides a clear picture of a system; this enhances understanding through visual representation. The network has nodes and branches, the nodes represent locations while the branches represent a flow by joining the nodes. When a program or a project is represented inform of a network flow, it is efficient to identify an existing problem and identify ways to deal with the problem.

Salivary Amylase and Other Enzymes in Saliva

Salivary Amylase and Other Enzymes in Saliva When food enters the mouth, it triggers the release of saliva. Saliva contains enzymes that perform important biological functions. Just like other enzymes in the body, the salivary enzymes help to catalyze, or speed up, the rate of chemical reactions in the body. This function is required to promote digestion and the acquisition of energy from food. Major Enzymes in Saliva Salivary amylase (also known as ptyalin) breaks down starches into smaller, simpler sugars. Salivary kallikrein helps produce a vasodilator to dilate blood vessels. Lingual lipase helps to break down triglycerides into fatty acids and glycerides. Salivary Amylase Salivary amylase is the primary enzyme in saliva. Salivary amylase breaks down carbohydrates into smaller molecules, like sugars. Breaking down the large macromolecules into simpler components helps the body to digest starchy foods, like potatoes, rice, or pasta. During this process, larger carbohydrates, called amylopectin and amylose, are broken down into maltose. Maltose is a sugar that is composed of individual subunits of glucose, the human bodys key source of energy.   Salivary amylase also has a function in our dental health. It helps to prevent starches from accumulating on our teeth. In addition to salivary amylase, humans also produce pancreatic amylase, which further breaks down starches later in the digestive process. Salivary Kallikrein As a group, kallikreins are enzymes that take high molecular weight (HMW) compounds, like kininogen, and cleave them to smaller units. Salivary kallikrein breaks down kininogen into bradykinin, a vasodilator. Bradykinin helps to control blood pressure in the body. It causes blood vessels to dilate or expand and causes blood pressure to be lowered. Typically, only trace amounts of salivary kallikrein are found in saliva. Lingual Lipase Lingual lipase is an enzyme that breaks down triglycerides into glycerides and fatty acid components, thus catalyzing the digestion of lipids. The process begins in the mouth where it breaks down the triglycerides into diglycerides. Unlike salivary amylase, which functions best in non-acidic environments, lingual lipase can operate at lower pH values, so its action continues into the stomach. Lingual lipase helps infants digest the fats in their mothers milk. As we get older, the relative proportion of lingual lipase in saliva decreases as other parts of our digestive system help with fat digestion. Other Minor Salivary Enzymes Saliva contains other minor enzymes, like salivary acid phosphatase, which frees up attached phosphoryl groups from other molecules. Like amylase, it helps with the digestion process. Saliva also contains lysozymes. Lysozymes are enzymes that help to kill bacteria, viruses and other foreign agents in the body. These enzymes thus perform antimicrobial functions.
