Salt And Its Uses :: essays research papers

Salt and Its Uses As we know, salt is the most useful resource found on earth. In Ancient Rome, salt was used as part of the salary to the soldiers. From this, we can see that salt was as valuable as gold in the past. In our daily life, besides making nutritious food more palatable, salt is very useful in making bakery products, canned and frozen foods. Salt is a good preservative that retards the growth of micro-organisms to make food storage possible for a long period of timie before refrigeration. Recently, an opinion that is harmful to our health was raised by Dr. Arthur Hull Hayes, Jr,. former comissioner of the U.S. Food and Drug Admistration in 1981. The American Heart Dissociation, the American Medical Association also joined the low-salt appeal. They believe that sodium salt is connected with heart disease, circulator disorder, stroke and even early death. By many doctors and researchers are now beginning to feel that salt has gone too far. At the University of Alabama, a short-term research has been done on 150 people on the effect of the intake of salt related to high blood pressure. Result shows that those with normal blood pressure experience no change at all when placed in a extremely low salt diet, or later when salt was introduced, Of the hypertensive subjects, half of those on the low salt diet did experience a drop in blood pressure, which returned to its previous leel when salt was introduced. Of course, these are other researcherswhgich tend to support the findings. A small Indiana study showed that when normal individuals took large amount of salt, the bolld pressure did not consistenly rise into the hypertensive range. Also, study in Israel showed that a low-calorie diet could reduce blood pressure without changing salt consumption. After viewing research statistics, we should know that salt is not exactly harmful to us. In fact, our bodies have a continual need for salt because our bodies need sodium and chloride ions each with a different task. Chloride maintains the balance of water in cells and its environment. It also plays a part of digestion. Sodium assists in regulating the volumn of blood and blood pressure. Also, it facilitates the transmission of nerve impulses and is necessary for heart and muscle contraction. Without this, our bodies could not function properly.

The E-commerce website should be built on the security technology and it should be very secure. Secure Sockets layer provides support for protect pages and encrypts the whole thing a user sends-nobody else can read the data . Strong encryption and authentication certificate makes web site more secure and invites more customers. ( Lee, 2001) 2. Features of E-commerce: Ubiquity: Is the ability to be present in every place at any time, unbounded or universal presence.

Given It has possibilities to who feels the message from where gold which machine. Without appropriate authentication, it very hardware to know which passed year order and the order placed is true gold not. (David, 2000) Non-repudiation: it’s much closed to the authentication, in this sender boat refuses the sending particular messages and receiver boat rejects the receiving messages.

Improving Efficiency with Business Process Modeling

In order for businesses to be successful, they must find out what the customer wants and meet that need. This can be difficult when dealing with the ever-evolving trends of today’s society. Businesses must remain flexible and constantly be experimenting with new technology and ideas to better provide their services to the customer. To help accomplish this goal, Business Process Modeling can be used to provide a solution, to help refine and organize business processes, which may in return make the business more efficient. A key feature of any successful business is how the business provides its services to customers. This is often done through business processes, a collection of organized tasks or activities that are intended to accomplish a specific goal. (Pittarese, 2014) These tasks may encompass different functional areas and are designed to â€Å"create value for the customer.†(Pittarese, 2014) Though a business is successful and may have been around for quite some time, they often find the need to update their business processes, in order to keep up with customer demands, technological advances, and to improve efficiency within their company.
