In this paper, we introduce a method of generating the dual graph of the minimal normal resolution of the algebraic curve singularities. Using factorization of polynomials over algebraic extension field, we can calculate the dual graph from the coefficients of the given polynomial exactly. The computing process includes no approximation. We constructed the system to generate the dual graph on R...

The biofilm community structure in a granular activated carbon (GAC) filter was investigated by ribosomal intergenic spacer region analysis (RISA). The results showed that microbial diversity diminished and stabilized with time of filter operation. One bacterium (Hydrogenophaga palleronii) was identified according to its 16S-rRNA sequence. However, this bacterium did not degrade any of the HAAs...

La susceptibilidad al refuerzo puede distinguirse entre (refuerzo) inmediato y demorado. Por otro lado, la gaudibilidad se concibe como el conjunto de moduladores que regulan disfrute experimentado. No existen estudios previos relacionen ambas variables. El objetivo del presente estudio fue estudiar relación sus factores Susceptibilidad Refuerzo Inmediato Demorado factores. Para ello, administr...

A survey has been made of the amount of muscle water available to inulin, sucrose, and radioiodinated human serum albumin (RISA). The percentage spaces available to the three molecules are of the same order of magnitude, but the sucrose space > inulin space > albumin space. The kinetics of influx and efflux of RISA have been studied, and it appears that a small part of the albumin may be adsorb...

The external microbiome of fish is thought to benefit the host by hindering the invasion of opportunistic pathogens and/or stimulating the immune system. Disruption of those microbial communities could increase susceptibility to diseases. Traditional aquaculture practices include the use of potent surface-acting disinfectants such as potassium permanganate (PP, KMnO4) to treat external infectio...

Disruption of the blood-brain barrier (BBB) during acute hypertension may contribute to hypertensive encephalopathy. In this study we tested the hypothesis that, in chronic hypertension, vascular changes might influence the susceptibility of the BBB to disruption. Spontaneously hypertensive rats (SHR) and normotensive rats (WKY), 3-4 months of age, were anesthetized and acute hypertension was p...

Despite decades of research, the ecological determinants of microbial diversity remain poorly understood. Here, we test two alternative hypotheses concerning the factors regulating fungal diversity in soil. The first states that higher levels of plant detritus production increase the supply of limiting resources (i.e. organic substrates) thereby increasing fungal diversity. Alternatively, great...

In this paper, we address the issue of dynamically allocating resources to a group of streams belonging to a distributed multimedia application that reserves a collective amount of resources to be shared by its streams. The traac characteristics of the streams are speciied using the M-LBAP (Modiied Linear Bounded Arrival Processes) model. The M-LBAP model provides tight characterization for the...

A series of additives were evaluated for their effects on improving the yield and quality of DNA extracted from recalcitrant soils. Levels of possible DNA contaminants in these supplements were also assessed. Three of the additives (skim milk, casein, and RNA) were shown to be effective in improving the stable extraction of DNA from recalcitrant samples of Andosol. However, whereas skim milk ap...
