One is the traditional application system suc h as MIS and Business Software. Along with its extension, the traditional applic ation system transforms from file-based structure to C/S and then CSS model. At the same time, following the prevalence of Internet/Intranet, Web application s ystem based on browser comes into being. In early time, Web application only pro vided functions of looking over or querying static data on browser. But with the development of Internet/Intranet widely, it’s expected that more and more trad itional applications can be performed on browser, or even E-Business trades and other complicated application systems such as MIS, ERP and CRM and so on. In or der to satisfy both traditional application and Web application, reduce the cost of developing system repeatedly, increase the repeated use of application syste m and take advantage of the functions of OOA/OOD sufficiently, a new distributed architecture structure (system solution based on repeated components) comes for th. In this article, this distributed architecture structure will be discuss ed in detail. Firstly, the evolution of traditional application system and Web application sys tem will be talked over, especially the advantages and disadvantages of these tw o architectures. Secondly, the distributed architecture (system solution based o n repeated components) will be described particular. Several prevalent technolog y of component, such as COM+, CORBA and EJB, will also be illustrate d in this part. Thirdly, the practice of the technology of repeated component wi ll be discussed by analysing and designing the management system of Science & Te chnology Articles.

In the end, Based on summing-up o f the distributed technology of E-Business, the future distributed tenchnology of E-Business will be expected.展开更多

Many methods are used to preserve the juice or the paste through drying and with addition of preservative. Tomato grows under ambient conditions or in green houses at a temperature of 20°C - 27°C with high contents of vitamins A and B, potassium, iron, and phosphors. Tomato is a source of fiber;it doesn’t contain sodium salt, fats, or cholesterol;in fact it is the cheapest food of the poor common people. Tomato while waiting for processing to paste deteriorates rather quickly, and shall be thoroughly rinsed with sterilized clean water using rotary washers. The washed tomato is inspected, sorted, and chopped. The tomato liquor is processed through an extraction unit where the juice is separated away from outer skin, seeds and fibers. To avoid oxidation and foaming the tomato liquor is deaerated;the juice is deaerated by taking the vacuum as soon as it is formed. A double-effect evaporator is used to concentrate the tomato liquor under partial vacuum of 0.5 atmospheres;this is important to minimize heat damage, oxidation and dark color. The tomato paste is then sterilized with small amount of non-harmful preservatives and then canned, labeled and sent to store. To achieve the international standard specifications and metrology organization a control system is developed, tuned and analyzed for stability conditions. It is recommended that a tomato production plant has to be constructed in countries like Sudan and other countries with similar weather conditions.展开更多
