Main indicators of population migration in the Russian Federation and their dynamics

The dynamics of internal and international migration processes in the Russian Federation in 2015–2019 is studied. The results of a comparative statistical study carried out for three process indicators and 120 factors are presented. The indicators for 2020 are not included in the comparative analysis, as they are not typical for Russia and are caused by the pandemic

Some recommendations and examples in the activation therapy practical implementation (according to L.K. Garkavi, E.B. Kvakina and M.A. Ukolova’s research studies)

Knowledge of laws of the different organism reactions to external and internal influences in case both of general unspecific adaptational reactions of different types and the periodic system of the repetitive pattern reactions offers us a possibility to target and control the organism resistance level using the activation therapy methods. Given are some examples of using the available biologically active means and the programmed modes of their dosing which demonstrate simplicity and efficacy of the stable health state restoration and maintenance

Energetic criteria of lymphocytes in evaluation of efficacy of system processes correction under oncopathology

The activity of key ferments in the Krebs cycle (SDH) and glycolysis (α-GPDH) in peripheral blood lymphocytes in animals and humans with cancer pathology is considered herein. Identified is a close relationship between the fermentative activity and non-specific integral reactions of an organism, the type of which can be regulated by factors of electromagnetic nature. Monitoring of signal energetic and adaptive reactions permits to adequately evaluate an efficacy of treatment and predict recovery

Al and Ti location in the MFI orthorhombic HZSM-5 framework. DFT calculation and neutron diffraction experiment

Abstract For the first time the neutron diffraction study of HZSM-5 zeolites with the general composition of (H1+x)[Al3+xSi4+12-xO24] × wH2O in the orthorhombic approximation (sp. gr. Pnma, z = 8) and initial silicate modules Si/Al = 12, 25, 40 was carried out. As a result, the composition was refined, the distribution of Al3+ ions over the tetrahedral sites (T sites) of the structure was found, and their content in each of them was estimated. It was found that T sites occupation in HZSM-5 structure differ depending on Si/Al, while samples with the same silicate module (Si/Al = 40) obtained under different synthesis conditions differ in the distribution of Al3+ ions over T sites of the structure. It was shown that the calculation of HZSM-5 zeolites crystal structure with substitutions in T sites performed using the VASP 5.2 program with different optimizations (atomic coordinates and unit cell parameters) can only reveal the most thermodynamically energetically favorable sites for Si4+ atoms substitution with other atoms (aluminum and titanium) without predicting their content in each site and regardless zeolite synthesis conditions and type of substituent atom. The relationship between HZSM-5 zeolites catalytic properties and silicate module (Si/Al, Si/Ti) was found and it cannot be ruled out that HZSM-5 catalytic activity is related to Ti4+ ions distribution over the tetrahedral sites of the structure.

Processes in regulatory systems during development of various adaptational reactions and evaluation of functional state dynamics in the organism

The paper describes some concepts on processes occurring in the neuroendocrine and immune systems during development of general unspecific adaptational reactions. The concepts are based on the known evidence on the changes in the regulatory systems and the previously identified peculiarities in correlations between the levels of biogenic amines in blood and the organs, respectively, under various adaptational reactions, as well as the known effects of biogenic amines. A number of practical consequences significant for the correct evaluation of the functional state in humans and animals are also considered herein

Shewanella affinis sp. nov. isolated from marine invertebrates

Four marine bacterial strains, designated KMM 3587T, KMM 3586, KMM 3821 and KMM 3822, were isolated from the sipuncula Phascolosoma japonicum, a common inhabitant of Troitza Bay in the Gulf of Peter the Great (Sea of Japan region), and from an unidentified hydrocoral species collected in Makarov Bay (Iturup Islands), Kuril Islands, North-West Pacific Ocean. The strains were characterized to clarify their taxonomic position. 16S rRNA gene sequences of KMM 3587T and KMM 3586 indicated 99 % similarity to Shewanella colwelliana. Despite such a high level of 16S rRNA gene sequence similarity, DNA–DNA hybridization experiments demonstrated only 45–52 % binding with DNA of S. colwelliana ATCC 39565T. The DNA G+C contents of the novel strains were 45 mol% and the shared level of DNA hybridization was conspecific (81–97 %), indicating that they represent a single genospecies. The novel strains were mesophilic (able to grow at 10–34 °C), neutrophilic and haemolytic, and able to degrade gelatin, casein and Tween 20, 40 and 80, but not starch, agar, elastin, alginate or chitin. The major fatty acids were i13 : 0, i15 : 0, 16 : 0, 16 : 1{omega}7 and 17 : 1{omega}8 (68·9 % of total). The major isoprenoid quinones were Q7 (47–62 %) and Q8 (26–47 %). Eicosapentaenoic acid was produced in minor amounts. Based on these data, the strains are assigned to a novel species, Shewanella affinis sp. nov. (type strain KMM 3587T=CIP 107703T=ATCC BAA-642T)
