in this study, a simple and low-cost method was developed for extraction and pre-concentration of brilliant blue(bb) and tropaeolin o(to) in food samples using cloud point extraction (cpe) prior to spectrophotometric determination. the effects of main factors such as ph, surfactant and salt concentrations, incubation time and temperature on the cloud point extraction of both dyes were investiga...

This paper advocates the use of self-stabilization as a provable property to achieve the goals of the self-* paradigms for systems, including availability, reliability, serviceability, disaster recovery and autonomic computing. Several recent results starting from hardware concerns, through the operating system, and ending in the applications are integrated: the selfstabilizing microprocessor [...

Studying parallelism and concurrency in the double-pushout approach to graph transformations is mainly based on the so-called triple-pushout condition. The categories of sets and of graphs satisfy this condition. If we, however, consider graph morphisms that may change the labels in a welldefined manner (structurally labeled graphs), the triple-pushout condition does no longer hold true. In thi...

objective(s): htlvi-1 is the first human retrovirus with limited endemic regions in the world. the epidemiological studies have shown that the genetic background and immune response to the virus have a significant role in htlv-i-associated diseases.  among the genes are involved in htlv-i infection, the role of human leukocytes antigen (hla) have been studied in different population. in the pre...

For testing problems of the form Ho : v = Vo with unknown nuisance parameter (). a variety of methods are used to deal with (). The simplest approach is exemplified by the t test where the unknown variance is replaced by the sample variance. and the t distribution accounts for estimation of the variance. In other problems such as the two by two contingency table. one conditions on a sufficient ...
