The maximum allowable biological concentration of a toxic substance is the highest concentration which can be found in a biological medium without damage to health. The biological materials rna y be examined for: (a) the toxic substance itself; (b) a product of the metabolism of the toxic substance in the body; (c) a substance derived from the physiopathological activity of the toxic substance;...

double bridge girder overhead cranes are used for heavy duty applications in theindustry. in this paper a detailed parametric design optimization of the main girder of box type isperformed for a 150ton capacity and 32m long span crane, after its basic design using availabledesign rules. design optimization is performed using detailed 3d finite element analysis bychanging the number, shape and l...

acute toxicity test on common carp weighing 18 grams and length 12 cm was performed. with concentrations of 0, 2, 5, 10, 20, 40, 60, 80, 100, 200, 400, 600, 800 and 1000 ppm measured at 0, 24, 48 and 96 hours were considered for commercial diesel . processing data using spss software and statistical analysis probit analysis was performed with a confidence level of 95%. the common carp no deaths...

A generalized numerical semigroup is a submonoid $S$ of $\mathbb{N}^d$ for which the complement $\mathbb{N}^d\setminus S$ finite. The points in are called gaps. gap $F$ considered Frobenius allowable if there some relaxed monomial ordering on with respect to largest gap. We characterize gaps semigroup. that has only one maximal under natural partial show semigroups precisely those whose does no...
