مالاریا یکی از بیماری های مهم انگلی در کشورهای گرمسیری دنیا است. پلاسمودیوم فالسیپاروم انگل تک یاخته ای است که تب سه یک بدخیم را ایجاد می کند. آنتی ژن های پلاسمودیوم فالسیپاروم در سطح انگل یا در سطح سلول های آلوده ،کاندیداهای عمده جهت تولید واکسن می باشند، مانند: msp 1 و msp2 . کربوهیدرات های متصل به پروتئین های انگل مالاریا بعنوان اپی توپ های آنتی ژنیک مطرح بوده و بوسیله سیستم ایمنی میزبان تشخ...
The recent move towards market deregulation and open competition has sparked a wave of serious introspection in the telecommunications service industry. Telecom providers and operators are now required to open up their primary revenue channels to competing industries. In this paper, we examine the service structure of two major global communication networks the Telephone Network and the Interne...
This chapter describes how the changing information about an individual’s location, environment, and social situation can be used to initiate and facilitate people’s interactions with one another, individually and in groups. Context-aware communication is contrasted with other forms of context-aware computing and we characterize applications in terms of design decisions along two dimensions: th...
The telecommunications sector has become a dynamic key area for the economic development of the European Union (EU) and remains in constant evolution. Because of intense competition, telecommunications companies are forced to diversify their offers and thus to propose an increasing number of services. However, economic analysis often ignores important technical aspects of telecommunications and...

In the recent past, there have been many technological developments such as digitization of information, optical networks, internet, and wireless networks. These developments have led to a series of new optimization problems. This manuscript gives an overview of the developme...

After a discussion of the processes linking telecommunication use to cultural values, we show on empirical grounds the relationship between the preference of the individual for organizational cultures and his or her telecommunication use (fax, em...
Telecommunication towers are among the few steel structures that little attention has been paid to their seismic behavior in existing design codes. Due to lack of design provisions, the designers apply the existing building design codes to telecommunication towers. However, the seismic behavior and response of telecommunication towers is very different from that of building structures. For exam...
MDA (Model-Driven Architecture) has been coined by OMG (Object Management Group) as the next step in application integration. Being based on standards already embraced by a large segment of the software engineering industry, MDA promises fully automatic model transformation. MDA enables application developers to use formalisms such as UML to specify their applications in a totally platform-inde...
Authentication is a security service that consists of verifying that someone’s identity is as claimed. There are a number of challenges to presenting information from the authentication process to the user in a way that is meaningful and ensures security. We show examples where authentication requirements are not met, due to user behaviour and properties of existing user interfaces, and suggest...
