The widespread use of wireless cellular networks has made security an ever increasing concern. GSM is the most popular wireless cellular standard, but security is an issue. The most critical weakness in the GSM protocol is the use of one-way entity authentication, i.e., only the mobile station is authenticated by the network. This creates many security problems including vulnerability against m...
Many substances of plant origin are extracted for use in the primary treatment domestic wastewater. In most cases, they used as coagulating and flocculating agents derived from seeds, leaves, bark or sap, roots, fruits trees plants. this research, Cassia fistula seed was evaluated removal turbidity color wastewater a pumping station city Cartagena (Colombia). The optimal dose C. powder determin...
If depicted objects visually remain where they are, but are linguistically described as moving to new locations (‘onto the table’), subsequent reference to them directs attention to their new locations. But, do these attentional shifts depend on updated spatial screen coordinates, or new object associations? We investigated situations wherein depicted containers moved between spatial locations ...
This study was undertaken to determine the roles of individual alpha/beta 1 integrin heterodimers in promoting cellular interactions with the different attachment-promoting domains of laminin (LN). To do this, antibodies to the integrin beta 1 subunit or to specific integrin alpha subunits were tested for effects on cell attachment to LN, to elastase fragments E1-4 and E1, derived from the shor...
BACKGROUND: Embryo implantation requires that uterine epithelium develops competence to bind trophoblast to its apical (free) poles. This essential element of uterine receptivity seems to depend on a destabilisation of the apico-basal polarity of endometrial epithelium. Accordingly, a reorganisation of the actin cytoskeleton regulated by the small GTPase RhoA plays an important role in human ut...
the aim of this study was to evaluate the effect of maltodextrin supplementation on blood glucose and anaerobic indices of the young male athletes. 30 young male athletes were selected as the sample and assigned to two groups: carbohydrate (cho: n=15; mean and sd age 16.67±0.8 years, height 171.27±5.22 cm, weight 67.87±4.29 kg) and control (cont: n=15; mean and sd age 16.73±1.03 years, height 1...
cacl2 treatment followed by heat shock is the most common method for artificial transformation. here, the cells were transformed using cacl2 treatment either with heat shock (standard protocol) or without heat shock (lab protocol) to comprehend the difference in transformation efficiency. the bl21 strain of escherichia coli (e. coli) was being susceptible using cacl2 treatment. some cells were ...
Quality models are needed to evaluate and set goals for the quality of a software product. The international ISO/IEC standard 9126 defines a general quality model for software products. Software is developed in different domains and the usage of the ISO/IEC quality model requires an instantiation for each concrete domain. One special domain is the development and maintenance of test specificati...
