Databases serving OLTP operations generated by cloud applications have been widely researched and deployed nowadays. Such cloud serving databases like BigTable, HBase, Cassandra, Azure and many others are designed to handle a large number of concurrent requests performed on the cloud end. Such systems can elastically scale out to thousands of commodity hardware by using a shared nothing distrib...

In data grids scientific and business applications produce huge volume of data which needs to be transferred among the distributed and heterogeneous nodes of data grids. Data replication provides a solution for managing data files efficiently in large grids. The data replication helps in enhancing the data availability which reduces the overall access time of the file. In this paper an algorith...

Abstract Meaningful work is the subjective experience that has meaning and understood as an avenue for personal development, from a eudaimonic point of view. The aim this study to adapt WAMI scale meaningful Spanish, well explore its relationship with job life satisfaction. Two independent studies were developed. A first analyzed consistency original factorial model using sample Spanish varied ...

SRC kinases and PKR are intracellular protein kinases, which play key roles in intracellular viral replication. In this research, the effect of SRC kinase inhibition and PKR activation and inhibition on replication of coxsakievirus (CVB3), an entrovirus of the family picornaviridae – causative agents of fatal myocarditis, was studied. Vero and Hela cells were cultured and infected with CVB3 in ...

objective: in this paper, we have introduced topoisomerase inhibitors, mechanism of action and types of them. dna topoisomerases are ubiquitous enzymes that catalyze essential enzymes to solve the topological problems accompanying key nuclear processes such as dna replication, transcription, repair and chromatin assembly by introducing temporary single or double strand breaks in the dna. result...

abstract— data grids are an important branch of gird computing which provide mechanisms for the management of large volumes of distributed data. energy efficiency has recently emerged as a hot topic in large distributed systems. the development of computing systems is traditionally focused on performance improvements driven by the demand of client's applications in scientific and business ...

conclusions after seven consecutive passages of both cell cultures, the h9n2 virus showed similar antigenicity, also no change on viral titer level and virus replication behavior in adaptation was found. the results highlighted the use of a549 cells for efficient virus isolation. results the influenza virus infectivity was not significant difference in these cells in the presence of trypsin. th...

This study discusses the utilization of three types of relationships in performing data replication. As grid computing offers the ability of sharing huge amount of resources, resource availability is an important issue to be addressed. The undertaken approach combines the viewpoint of user, system and the grid itself in ensuring resource availability. The realization of the proposed strategy is...

We designed the Land Information System (LIS) to perform global land surface simulations at a resolution of 1-km or finer in real-time. Such an unprecedented scale and intensity in computing pose many challenges. In this article we will demonstrate some of our unique developments and implementations in high performance computing with a Beowulf Linux cluster, to meet these challenges and reach o...
