CONTEXT Public health practitioners, policy makers, and researchers alike have called for more data on individual worker's perceptions about workplace environment, job satisfaction, and training needs for a quarter of a century. The Public Health Workforce Interests and Needs Survey (PH WINS) was created to answer that call. OBJECTIVE Characterize key components of the public health workforce...

This paper is to consider the scheduling of jobs to the resources in grid networks. In this paper, a scheduling system for computational grids with a mobile-agent based method is proposed. The main contribution of this work is to maximize throughput and minimize the entire response time of executing user applications. The proposed system is compared with a scheduling system that uses a recent s...

Grid computing is a form of distributed computing that involves coordinating and sharing data storage and network resource. The goal of grid job scheduling is to achieve high system throughput and match the job to the appropriate available computing resource. The complexity of scheduling problem increases with heterogeneous nature of grid and is highly difficult to schedule effectively. Existin...

Grid computing allows sharing and coordinated use of diverse resources in dynamic distributed virtual organizations. The objective is to best scheduling of tasks which attain maximum resource utilization, minimum response time and a well-balanced load across all the resources involved in a grid. Faulttolerant scheduling is an imperative step for large-scale computational Grid systems which uses...

Recently, many studies have attempted to utilize mobile nodes as resources in mobile grids. Due to their underlying restrictions such as intermittent communication disconnections, limited battery capacity, and so on, mobile nodes are less reliable than wired nodes for job processing. Therefore, it is imperative to find an enhanced job scheduling method to provide stable job processing for mobil...

Data-intensive applications executing over a computational grid demand large data transfers. These are costly operations. Therefore, taking them into account is mandatory to achieve efficient scheduling of dataintensive applications on grids. Further, within a heterogeneous and ever changing environment such as a grid, better schedules are typically attained by heuristics that use dynamic infor...

Our main objective in this paper is to study the possible benefits of using task replication when generating a schedule in a desktop grid. We consider the problem of constructing a schedule in an environment where machines’ speeds may be unpredictable and the objective is to minimize the makespan of the schedule. Another considered objective is to minimize the Total Processor Cycle Consumption ...

herpes simplex virus (hsv) is one of the common pathogenic viruses of humans bing. this study aimed to determin anti-herpes virus activity of mentha piperita extracts in vitro. mentha piperita extracts can inhibit hsv infection when the cells treated before viral adsorbtion. hsv-1 were also inhibited by menthol after viral adsorption. hsv-1 viral particles were directly inhibited and viral yiel...

australian grapevine viroid (agvd), an apscaviroid of the family pospiviroidae, was recently identified in vineyards of southern iran. it had a relatively wide host range and caused stunting, leaf deformation, mottling and vein clearing in experimental hosts upon mechanical inoculation of nucleic acid extracts or agroinfiltration of the viroid infectious cloned dna. predicted secondary structur...
