Efficient production system as part of sustainable environmental management

Rational use of natural resources is an integral part of building a production system in conditions of modern limited natural benefits and increasing the value of the quality of the natural environment around man. An efficient production system is at the heart of ensuring rational environmental management and the implementation of the UN's global goal of ensuring the transition to sustainable consumption and production patterns. The article is aimed at disclosing the concept and potential possibilities of using efficient production systems not only within the framework of environmental preservation, but also within the framework of ensuring the most rational use of state resources when pursuing a policy of import substitution. The authors of the article formulate a conclusion about the current state and prospects of using efficient production systems in the Russian Federation. © Published under licence by IOP Publishing Ltd

Proteins responsible for lysogenic conversion caused by coliphages N15 and phi80 are highly homologous.

Lysogenic conversion caused by lambdoid bacteriophage phi80 and that caused by coliphage N15 have similar characteristics, suggesting that similarities in their cor genes and Cor proteins are responsible for this effect. Here we present the nucleotide sequence of the N15 cor gene. The N15 cor gene homolog was found in the phi80 cor region, but in the opposite direction of that of the open reading frame to which the phi80 cor gene had previously been assigned (M. Matsumoto, N. Ichikawa, S. Tanaka, T. Morita, and A. Matsushiro, Jpn. J. Genet. 60:475-483, 1985)

History of women’s political and civil rights in denmark

Today, Denmark is one of the five leading countries in terms of the protection of women's rights. Legislative consolidation of women's suffrage took place at the beginning of the 20th century, but the heyday of the feminist movement occured after the Second World War. The authors analyse the history of women's rights in Denmark and the role of the feminist movement in this process. © 2020, Rossiiskaya Akademiya Nauk, Institut Istorii (Russian Academy of Sciences, Institute of General Hist.

Genomic sequence and analysis of the atypical temperate bacteriophage N15

N15 is a temperate bacteriophage that forms stable lysogens in Escherichia coli. While its virion is morphologically very similar to phage lambda and its close relatives, it is unusual in that the prophage form replicates autonomously as a linear DNA molecule with closed hairpin telomeres. Here, we describe the genomic architecture of N15, and its global pattern of gene expression, which reveal that N15 contains several plasmid-derived genes that are expressed in N15 lysogens. The tel site, at which processing occurs to form the prophage ends is close to the center of the genome in a similar location to that occupied by the attachment site, attP, in lambda and its relatives and defines the boundary between the left and right arms. The left arm contains a long cluster of structural genes that are closely related to those of the lambda-like phages, but also includes homologs of umuD', which encodes a DNA polymerase accessory protein, and the plasmid partition genes, sopA and sopB. The right arm likewise contains a mixture of apparently phage- and plasmid-derived genes including genes encoding plasmid replication functions, a phage repressor, a transcription antitermination system, as well as phage host cell lysis genes and two putative DNA methylases. The unique structure of the N15 genome suggests that the large global population of bacteriophages may exhibit a much greater diversity of genomic architectures than was previously recognized.
