Background: Clearing is an important step in the preparation of histological sections, that removes alcohol and other dehydrants from tissues prior to infiltration of the embedding material (usually paraffin wax).Different types of clearing agents are chloroform, Xylene, Toluene, Paraffin, Methyl benzoate and methyl salicylate & Citrus fruit oils.The commonly used clearing agent is xylene that ...

Processor co-allocation can be of performance benefit. This is because breaking jobs into components reduces overall cluster fragmentation. However, the slower inter-cluster communication links increase job execution times. This leads to performance deterioration which can make co-allocation unviable. We use intra-cluster to inter-cluster communication speed ratio and job communication intensit...

The abdominal ganglion of Aplysia californica was perfused with artificial seawater equilibrated at different P(COCO2)'s and pH's for 5 min or less. 5% CO(2) dropped perfusate pH from 8.0 to 6.5 and produced depolarization and increased discharge rate in visceromotor neurons. Half the giant cells studied had a similar response, whereas the other half were hyperpolarized. Pacemaker neurons showe...

This article proposes offline language-free writer identification based on speeded-up robust features (SURF), goes through training, enrollment, and identification stages. In all stages, an isotropic Box filter is first used to segment the handwritten text image into word regions (WRs). Then, the SURF descriptors (SUDs) of word region and the corresponding scales and orientations (SOs) are extr...

Plant physiological adaptation to the global rise in atmospheric CO(2) concentration (CO(2)) is identified as a crucial climatic forcing. To optimize functioning under rising CO(2), plants reduce the diffusive stomatal conductance of their leaves (g(s)) dynamically by closing stomata and structurally by growing leaves with altered stomatal densities and pore sizes. The structural adaptations re...

Objective(s):Serratia marcescens is one of the nosocomial pathogen. The ability to form biofilm is an important feature in the pathogenesis of S. marcescens. The aim of this study was to determine the anti-adhesive properties of a biosurfactant isolated from Lactobacillus acidophilus ATCC 4356, on S. marcescens strains. Materials and Methods: Lactobacillus acidophilus ATCC 4356, was selected a...
