    Description: One of the main tasks of modern genetics is the study of the genetic diversity of organisms of different taxonomic levels. Such genome studies can serve as a tool for solving problems associated with identifying the evolutionary mechanisms by which genetic diversity has emerged. Discussions are still ongoing on micro- and macroevolutionary processes that can lead to a variety of genes and taxonomic diversity in the species of the Prussian carp Carassius auratus gibelio Bloch. It should also be noted that these studies have started relatively recently, and many questions concerning the genetic research of carp are still open.
    Description: Одной из основных задач современной генетики является изучение генетического разнообразия организмов различного таксономического уровня. Такие исследования геномов могут послужить инструментом для решения проблем, связанных с выявлением эволюционных механизмов, с помощью которых появилось генетическое разнообразие. До сих пор ведутся дискуссии относительно микро- и макроэволюционных процессов, которые могут приводить к разнообразию генов и таксономическому разнообразию у видов серебряного карася Carassius auratus gibelio Bloch. Также нужно отметить то, что данные исследования начались относительно недавно, и многие вопросы, касающиеся генетических исследований карася, остаются открытыми.

    Description: Genetic engineering now makes possible the insertion of DNA from many organisms into other prokaryotic, eukaryotic and viral hosts. This technology has been used to construct a variety of such genetically engineered microorganisms (GEMs). The possibility of accidental or deliberate release of GEMs into the natural environment has recently raised much public concern. The prospect of deliberate release of these microorganisms has prompted an increased need to understand the processes of survival, expression, transfer and rearrangement of recombinant DNA molecules in microbial communities. The methodology which is being developed to investigate these processes will greatly enhance our ability to study microbial population ecology.

    Notes: The Fast Fourier Transform is employed as a method of Laplace transform inversion to solve problems in the civil engineering fields of visco-elasticity and hydrology. When these problems are accurately represented by a linear time-invariant model, it is shown that the Fast Fourier Transform inversion procedure is often more accurate than standard convolution and inversion techniques. The speed and accuracy of solution resulting from this application of the Fast Fourier Transform is illustrated by referring to case studies solved on an IBM 1130 computer, model 3D processor with 32K memory.

    Notes: Stress fields near crack tips in an elastic body can be specified by the stress intensity factors which are closely related to the stress singularities arising from the crack tips. These singularities, however, cannot be represented exactly by conventional finite element models. A new method for the analysis of stresses around cracks is proposed in this paper on the basis of the superposition of analytical and finite element solutions. This method is applied to several two-dimensional problems whose solutions are obtained analytically, and it is shown that their numerical results are in excellent agreement with analytical ones. Sufficiently accurate results can be obtained by the conventional finite element analysis with rather coarse mesh subdivision. Computational efforts are then considerably reduced compared with other methods.

    Notes: A generalized variational principle is presented, which leads to a modified finite element approach for three-dimensional field problems. Both, potential function and velocity field, are approximated by expansions which are continuous across the inter-element boundaries. The rapid convergence of this mixed model is shown by two examples.

    Notes: A computer program for the in-core solution of large, sparse, unsymmetric systems of linear equations is presented in this paper. The program employs elimination techniques for solution of systems of linear equations. A limited number of zeros is stored and trivial arithmetic is by-passed to preserve computer storage and to reduce the time required for solution. Several techniques for selecting the pivotal elements are discussed and their effect on accuracy and computational time are examined.
