Ninety-three samples of fresh and canned fish (edible part) collected from Lower Austria, Burgenland and from Viennese retail operations were analysed for mercury, lead and cadmium. The mercury contents ranged from <0,01 (limit of determination) to 0,89 mg/kg with a mean value of 0,14 mg/kg. The highest mercury contents were measured in Escolar (mean value of 0,63 mg/kg), followed by Swordfish ...

The Time Value of Money is a important concept in Financial Management. The Time Value of Money includes the concepts of future value and discounted value or present value. In the present article, the basic notions and illustrate with their application in the field of investment which is presented in the mathematical terms in form of theorems and we also presented the applications of some well ...

One of the most effective parameters in economics of open-pit mines is the pit slope angle, so that the slope angle more than the optimum value increases the probability of a large failure in the pit wall and the slope angle less than the optimum value leads to increasing stripping ratio and reducing net present value of mine. Therefore, in this paper, considering the limit equilibrium methods ...

The article discusses a boundary value problem of nonlinear elasticity for mapping (deformation) in two weak formulations: the form variational equilibrium equation and minimization multidimensional integral functional. Some questions mathematical correctness BVP are discussed. Using methods calculus variations, by example simple problems, it is proved that some elastic models corresponding pro...
