It is difficult to measure the transverse shear modulus of the fibrous composites. Thus, theoretical investigations by means of analytical and numerical techniques are paramount. In particular, they are important for the regime with high-concentration of fibers. We apply general techniques to study the mechanical properties of unidirectional fibers with a circular section embedded into the matrix...
The aim of review was to evaluateoptimal conditions for microorganisms growth from different taxa, includingyeast, bacteria and algae. Maximal efficiency of yeast Saccharomyces cerevisiae propagation occurs in aerated and constant low concentration of sugar medium. Optimal conditions for effective fermentation require high concentration of sugar which is converted into ethanol, however the produced...
