Abstract : In this paper , we apply the stochastic dynamic programming to approximate the mean project completion time in dynamic Markov PERT networks. It is assumed that the activity durations are independent random variables with exponential distributions, but some social and economical problems influence the mean of activity durations. It is also assumed that the social problems evolve in ac...

electronic banking has been around for some time in the form of automatic teller machines and telephone transactions but with the advent of internet, more publicity has been witnessed. this issue of internet has equally given a new look to their transactions and mode of product delivery in banking services for the benefits of both the customers and the banks. the objective of this paper is to f...

The study was designed to investigate the effects of dietary Selenium-enriched radish sprouts (Se-RS), Vitamin E (Vit E), and Rhodobacter capsulatus (RC) on immunity, cholesterol concentration, and fatty acid composition in broiler meat. A total of 100 two-week-old male broiler chicks were randomly assigned into five dietary groups: I) Control; II) Se-RS (5 μg/kg Se-RS); III) Se-RS+RC (5 μg/kg ...

Primary Health Care (PHC) is expected to serve as a basis for the countrychr('39')s health sector, of which it is the primary responsibility and priority, as well as the communitychr('39')s overall collective and economic prosperity. Promotion of food supply and proper nutrition are among eight elements of PHC. Protein deficiency is one of the most important health concerns in some parts of the...

site-directed mutagenesis (sdm) as a powerful technique was used to change two important and conserved amino acids in 5-enolpyruvylshikimate 3- phosphate synthase (epsps) gene of e. coli. the mutations changed glycine 96 to alanine and alanine 183 to threonine. these two amino acids are very important for intraction of the wide spectrum herbicide, glyphosate, to epsp synthase enzymes. by design...

Joining up services in e-Government usually implies governmental agencies acting in concert without a central control regime. This requires the sharing of scattered and heterogeneous data. Semantic Web Service (SWS) technology can help to integrate, mediate and reason between these datasets. However, since few real-world applications have been developed, it is still unclear which are the actual...

the health industry’s supply chain is full of uncertainty and unpredictability. thus, building an intelligent system to effectively capture the requirements of customers and help manage the supply chain is very important. despite artificial intelligence widespread acceptance as a decision-aid tool, ai has seen limited application in supply chain management. to fully exploit the potential benefi...

BACKGROUND Software development processes are often performed by distributed teams which may be separated by great distances. Global software development (GSD) has undergone a significant growth in recent years. The challenges concerning GSD are especially relevant to requirements engineering (RE). Stakeholders need to share a common ground, but there are many difficulties as regards the potent...

Introduction: This work investigates whether to conduct a medical study from the point of view of the expected net benefit taking into account statistical power, time and cost. The hypothesis of this paper is that the expected net benefit is equal to zero. Methods: Information were obtained from a pilot medical study that investigates the effects of two diagnostic modalities, magnetic resonance...
