One way to remedy the gap that evidently exists between the image element on the web and the web user who is visually blind is by redefining connection between the image and the abundant element of the web itself i.e. text. Studies on the web image automatic descriptors are largely done from the perspective of the fields of the He!. the semantic we

The purpose of this new investigation was to determine if spider webs exhibit antibacterial properties. In order to determine antibacterial properties, the spider webs were extracted with different solvents such as methanol, ethanol, acetone, and water in different conditions (extraction time, and concentration used for optimization). These extract

Twelve extracts from four solvents (ethanol, methanol, acetone and distilled water) and three varieties of date palm seeds (Deglet Nour, Biruni and Mixture) were tested in vitro for their antimicrobial activity against two Gram-positive (Staphylococcus aureus and Bacillus subtilis) and two Gram-negative (Escherichia coli, Pseudomonas aeruginosa) ba

Pectin is a complex polysaccharide found in the cell walls of plants and consisting mainly of esterified D-galacturonic acid resides in α-(1-4) chain. In production of fruit juice, pectin contributes to fruit juice viscosity, thereby reducing the juice production and increasing the filtration time. Polygalacturonase improves the juice production p

Design and development of new anticancer drugs with low toxicity is a very challenging task and computer aided methods are being increasingly used to solve this problem. In this research we investigate the anticancer activity of aliphatic nitrosoureas using quantum chemical quantitative structure activity relation (qcQAR) approach. In this method t

This paper attempts to design a triple band h-slot antenna by using feed line technique. These bands cover GSM mobile phone system (0.9 and 1.8 GHz) and ISM band which is used for Bluetooth and wireless local area network bands applications. The CST microwave studio software is used as a tool for simulation. This antenna is an attractive candidate

An inspiration for life-like recreation could have come from a meta-magical theme proposed by Hofstadter (1986) that reproduces patterns of genies from "Lucas Tower", '"Towers of Hanoi" and "Towers of Brahma". Perhaps the phenomenon of meta-magics may unveil the mysteries of genes through new designs of gene structures u

We have applied molecular dynamics methods as a tool in designing thermostable Bacillus circulans Xylanase, by examining Root Mean Square Deviation (RMSD) of enzymes structure at its optimum temperature and compare with its high temperature behavior. As RMSD represents structural fluctuation at a particular temperature, a better understanding of th

Molecular dynamics methods are very useful tool in understanding the behavior of the enzymes at higher temperatures. It is well known that some enzymes lose their enzyme activity at higher temperatures. In this work we employ molecular dynamics simulation of an endoglucanase from Fusarium oxysporum (EGFO) to understand the reasons behind the loss o
