Microglial cells within the developing central nervous system (CNS) originate from mesodermic precursors of hematopoietic lineage that enter the nervous parenchyma from the meninges, ventricular space and/or blood stream. Once in the nervous parenchyma, microglial cells increase in number and disperse throughout the CNS; these cells finally differentiate to become fully ramified microglial cell...

In this paper, the authors present an architecture and implementation of a distributed database system using sharding to provide high availability, fault-tolerance, and scalability of large databases in the cloud. Sharding, or horizontal partitioning, is used to disperse the data among the data nodes located on commodity servers for effective management of big data on the cloud. Database Shardi...

New bacteria that was provided from contaminated soils surrounding the coal, aluminum, salt mines and wetland separated, synthesized and characterized. The achievements show that this soils and waters have five disposed bacteria consist of Microbacterium SP, Micrococcaceae Bacterium, Planomicrobium SP, Brevndimonas Aurantiaca and Halomonas SP. Secondly, the result of the potential of remova...

In this paper we focus on two aspects: (1)the application of grid technology to allow a group of geographically disperse users to accomplish a given task collaboratively; (2) distributed scientific visualization through grid. Henceforth, we firstly describe some collaborative environments. Then, visualization techniques that can be implemented in grids are focused. These techniques can be integ...

Interacting, multi-robot systems show increasing promise for advances in exploration and defense applications. Here, we model a non-linear system of self-propelled individuals interacting via a pairwise attractive and repulsive potential. Depending on the interaction parameters, the agents may disperse, accumulate into self-organizing structures such as flocks and vortices, or collapse onto the...
