Extremal and maximal normal abelian subgroups of a maximal unipotent subgroup in groups of Lie type
AbstractWe describe all maximal abelian normal subgroups in the unipotent radical U of a Borel subgroup in a group of Lie type G over a field K. This gives a new description of the extremal subgroups in U which were studied by C. Parker and P. Rowley. For a finite field K, we prove that either each large abelian subgroup in U is G-conjugate to a normal subgroup in U or G is of certain exceptional Lie type

Higher School in Bashkir ASSR in 1950s— 1980s
The issue of the formation and development of the higher education system in the Bashkir ASSR in the 1950s—1980s is considered. The relevance of the study is due to the insufficient study ofthis problem in regional historiography. The novelty of the study lies in the fact that the article for the first time introduces into scientific circulation statistical information that was previously unused by researchers, characterizing the main areas of activity of universities in the republic. On the basis of published and archival sources, an increase in the number of students in full-time, part-time and evening departments of universities, admission, and release of qualified personnel by industry groups of educational institutions is shown in comparison with the all-Union indicators. The number of specialists graduated from universities in the period under review has been determined. The growth of scientific and scientific-pedagogical personnel, the peculiarities of the development of university science during this period are shown. It is concluded that in the 1950— 1980s. in Bashkiria, the formation and rapid development of the university system took place, in which more than half of the scientific potential of the republic was concentrated by the end of the period under study. It is indicated that, at the same time, its use in research work was extremely insufficient
Formation of Balmer lines in the spectra of X-ray Novae
The profiles and equivalent widths of the absorption and emission components of Balmer lines and the continuum optical spectra of X-ray novae during outbursts are calculated. A stationary self-illuminated accretion a disk around a Schwarzschild black hole is used as an instantaneous model for the X-ray nova. Each annulus of the disk is assumed to emit as a stellar atmosphere that is illuminated by the same X-ray flux. The irradiated stellar model atmospheres are calculated in the LTE approximation. The equivalent widths of the emission components of the Balmer lines are shown to depend on the X-ray flux that is intercepted by the disk (i.e., on the geometric sizes of the disk), on the optical depth of the chromospheric-like layer along the line of sight (i.e., on the inclination of the disk to the line of sight), and on the relative fraction of the soft component with E ∼ 0.1 keV in the X-ray spectrum (because it is this component that heats the upper atmosphere of the disk). A comparison of the theoretical spectra with the observed spectra of the X-ray nova V518 Per (GRO J0422+32) reveals an additional emission in the observed spectrum, which is most probably the bremsstrahlung of an optically thin, hot (T ∼ 106 K) shell

The spectral series of the Schrodinger operator with a delta-potential on a threedimensional compact spherically symmetric manifold in the semiclassical limit as h -> 0 are described
High-quality draft genome sequence of a new phytase-producing microorganism Pantoea sp. 3.5.1
© 2015 Suleimanova et al. Strain 3.5.1 was isolated from soils of the Republic of Tatarstan, Russia, on the basis of presence of a high phytate-degrading activity. Strains with such activities attract special interest because of its potential use as feed additives and natural manures. Strain 3.5.1 harbors a 99 % 16S rRNA nucleotide sequence similarity to different Pantoea species (P. vagans, P. ananatis, P. agglomerans, P. anthophila and Pantoea sp.) and exhibits unique biochemical properties that do not allow strain identification up to species. Moreover, the strain 3.5.1 shows a low ANI and MALDI-TOF Mass Spectrometry scores. Thus, it is likely that the strain 3.5.1 represents a new Pantoea species. Here, we present the genome sequence of Pantoea sp. strain 3.5.1. The 4,964,649 bp draft genome consists of 23 contigs with 4,556 protein-coding and 143 RNA genes. Genome sequencing and annotation revealed two phytase genes and putative regulatory genes controlling its activity
The association between <i>Candida albicans</i> sensitivity to antimycotic drugs and the architecture of their microbial community in the oropharynx of HIV infected patients
Relevance. Candida infection remains relevant due to the wide spread of antimycotic-resistant strains of Candida fungi, especially among immunocompromised individuals. It was previously discovered that the Candida spp. microbial community in the biotope of the oropharynx of HIV infected patients is characterized by a certain architecture: they can be present in this biotope in the form of a monoculture or as association of co-isolates. It has been suggested that the architecture of the Candida microbial community may influence their resistance to antimycotic drugs.
Purpose a comparative study of the association between the architecture of the C. albicans microbial community in the oropharynx of HIV infected patients with oropharyngeal candidiasis and their sensitivity to antimycotic drugs.
Materials and methods. A microbiological study of 52 isolates of Candida fungi (C. albicans, C. glabrata, C. tropicalis and C. krusei) from the oropharynx of 31 HIV infected patients with clinical manifestations of oropharyngeal candidiasis aged 20 to 69 years with almost equal gender distribution was carried out. In the form of monocultures, 18 isolates were isolated, while 34 were identified as co-isolates, which formed 16 homogeneous communities that included strains of the same species, and 18 heterogeneous ones that consisted of fungi of various species.
Results. It was found that heterogeneous communities of C. albicans were markedly distinguished by sensitivity to antimycotic drugs, in particular, by low sensitivity to imidazoles. Homogeneous communities practically did not differ from monocultural ones. The general properties of the C. non-albicans population were largely similar to those of C. albicans, but were characterized by lower heterogeneity in response to antimycotic drugs.
Conclusion. The architecture of the community of C. albicans isolated from the oropharynx of HIV infected patients with clinical manifestations of oropharyngeal candidiasis affects their sensitivity to antimycotic drugs. When selecting effective antimycotic therapy for such patients, it is necessary to take into account the structure of the Candida spp. community in the oropharynx
