This paper aims to solve the problem of the oxygen cylinder contribution to the overall scattering intensity of the open breathing diver, which is the basis for mastering the accurate prediction and identification of the diver.A two-dimensional finite element axisymmetric model of 3D-object with non-axisymmetric excitation is constructed.The numeri
Abstract Background In many animal species, interactions between individuals of different sex often occur in the context of courtship and mating.During these interactions, a specific mating partner can be chosen.By discriminating potential mates according to specific characteristics, individuals can increase their evolutionary fitness in terms of r
Here, we conducted in vitro genotoxicity tests to evaluate the genotoxicity of styrene oligomers extracted from polystyrene intended for use in contact with food.Styrene oligomers were extracted with acetone and the extract was subjected to the Ames test tennessee titans dog bandana (OECD test guideline No.471) and the in vitro chromosomal aberrati
