Innovations in civil engineering education at the interdisciplinary and production basis

Article is devoted to the problem of modernization of engineering education in modern economic conditions. This is necessary to provide qualified personnel for the construction industry. The authors considered innovative approaches to the organization of the educational process. They are based on interdisciplinary links of training of engineering and construction contingent in technical universities. And also on the introduction of digitalization in the teaching of disciplines of a natural science profile. We discussed the combination of traditional forms of training with production activities at existing enterprises of the industry. The work justified the relevance of modernization of engineering education, analysed factors that justify its need and ways to achieve the objectives. Studies have been carried out to assess the effectiveness of combining educational processes at the university with production activities at existing enterprises in Rostov-on-Don. To combine training and production processes in the training of qualified civil engineering personnel the structural division of the enterprise was allocated -the construction laboratory. The laboratory fully meets the tasks set by functional characteristics. Special working conditions of factory laboratories at small and medium-sized enterprises were noted. This is due to the difficult modern economic conditions. The main requirements for the personnel composition of factory laboratories of the new formation have been determined. These include depth and versatility of knowledge, non-standard thinking, flexibility in decision-making, interchangeability, readiness to improve knowledge and professional skills. The practical results of the experience of four years of combining innovative modernization of the training process of civil engineering personnel with production activities are presented. At the existing enterprises of the construction industry in Rostov-on-Don. The results confirm the high effectiveness of the proposed events

Supplementary Material for: Karyotype Evolution and Phylogenetic Relationships of Cricetulus sokolovi Orlov et Malygin 1988 (Cricetidae, Rodentia) Inferred from Chromosomal Painting and Molecular Data

<p>Sokolov's dwarf hamster (<i>Cricetulus sokolovi</i>) is the least studied representative of the striped hamsters (<i>Cricetulus barabensis</i> species group), the taxonomy of which remains controversial. The species was described based on chromosome morphology, but neither the details of the karyotype nor the phylogenetic relationships with other <i>Cricetulus</i> are known. In the present study, the karyotype of <i>C. sokolovi</i> was examined using cross-species chromosome painting. Molecular and cytogenetic data were employed to determine the phylogenetic position of Sokolov's hamster and to analyze the potential pathways of chromosome evolution in <i>Cricetulus</i>. Both the chromosome and molecular data support the species status of Sokolov's hamster. Phylogenetic analysis of the <i>CYTB</i> data placed <i>C. sokolovi</i> as sister to all other striped hamsters (sequence divergence of 8.1%). FISH data revealed that the karyotype of <i>C. sokolovi</i> is highly rearranged, with the most parsimonious scenario of its origin implying at least 4 robertsonian events and a centromere shift. Comparative cytogenetic data on Cricetinae suggest that their evolutionary history includes both periods of chromosomal conservatism and episodes of rapid chromosomal change.</p

Supplementary Material for: Genomic Organization and Physical Mapping of Tandemly Arranged Repetitive DNAs in Sterlet (Acipenser ruthenus)

Acipenseriformes represent a phylogenetically basal clade of ray-finned fish characterized by unusual genomic traits, including paleopolyploid states of extant genomes with high chromosome numbers and slow rates of molecular evolution. Despite a high interest in this fish group, only a limited number of studies have been accomplished on the isolation and characterization of repetitive DNA, karyotype standardization is not yet complete, and sex chromosomes are still to be identified. Here, we applied next-generation sequencing and cluster analysis to characterize major fractions of sterlet (<i>Acipenser ruthenus</i>) repetitive DNA. Using FISH, we mapped 16 tandemly arranged sequences on sterlet chromosomes and found them to be unevenly distributed in the genome with a tendency to cluster in particular regions. Some of the satellite DNAs might be used as specific markers to identify individual chromosomes and their paralogs, resulting in the unequivocal identification of at least 18 chromosome pairs. Our results provide an insight into the characteristic genomic distribution of the most common sterlet repetitive sequences. Biased accumulation of repetitive DNAs in particular chromosomes makes them especially interesting for further search for cryptic sex chromosomes. Future studies of these sequences in other acipenserid species will provide new perspectives regarding the evolution of repetitive DNA within the genomes of this fish order.<br
