New Rules on Confiscation of Electronics and Copying Information (Article 164<sup>1</sup> of the Code of Criminal Procedure Law): The Advantages and Disadvantages of the Novel
The article is devoted to the detailed analysis of the novel of the criminal procedural legislation defining the order of withdrawal of electronic media and copying of information from them. In December 2018, the Criminal Procedure Code of the Russian Federation was supplemented by article 1641 established “features of withdrawal of electronic data carriers and copying of information from them in the course of investigative actions”. At the moment, it is forbidden to withdraw electronic media in the investigation of cases in the field of business, except in cases established by law. The investigator has the right to copy information from electronic media. The requirement for the mandatory participation of a specialist in the seizure of electronic media, the legislator left unchanged. Assessing the legislative amendments, the authors substantiate the need to recognize as invalid the mandatory requirement for the mandatory participation of a specialist in the removal of electronic media
Synthesis and hydrophosphorylation of π-complexes of dibenzylideneacetone and cyclic conjugated dienones with homocarbonyl and carbonylcyclopentadienyl molybdenum compounds
© 2016, Pleiades Publishing, Ltd.Reactions of dibenzylideneacetone and cyclic cross-conjugated dienones with hexacarbonylmolybdenum(0) and bis[tricarbonyl(cyclopentadienyl)molybdenum(0)] afforded the corresponding complexes with η2-(C=C),η2-(C=O) coordination of the diketone to metal center, regardless of the ligand structure and initial molybdenum compound. The reactivity of the multidentate ligands may change as a result of coordination
In vitro conservation of Piper aduncum and Piper hispidinervum under slow-growth conditions
O objetivo deste trabalho foi avaliar a conservação in vitro de Piper aduncum e P. hispidinervum, em condições de crescimento lento. Os brotos foram armazenados a baixas temperaturas (10, 20 e 25ºC), e o meio de cultura foi suplementado com agentes osmóticos (sucrose e manitol – a 1, 2 e 3%) e ácido abcísico – ABA (0, 0,5, 1,0, 2,0 e 3,0 mg L-1). Após seis meses de armazenamentos os brotos foram avaliados quanto à sobrevivência e à rebrotação. A baixa temperatura de 20°C foi efetiva para a conservação in vitro de brotos de P. aduncum e P. hispidinervum. Culturas in vitro, mantidas a 20°C em meio MS apresentaram 100% de sobrevivência com o crescimento lento dos brotos. A presença de manitol ou ABA, no meio de cultura, afetou negativamente o crescimento de brotos, o que foi evidenciado pelo baixo índice de sobrevivência dos brotos. The objective of this work was to evaluate in vitro storage of Piper aduncum and P. hispidinervum under slow-growth conditions. Shoots were stored at low temperatures (10, 20 and 25°C), and the culture medium was supplemented with osmotic agents (sucrose and mannitol – at 1, 2 and 3%) and abiscisic acid – ABA (0, 0.5, 1.0, 2.0 and 3.0 mg L-1). After six-months of storage, shoots were evaluated for survival and regrowth. Low temperature at 20°C was effective for the in vitro conservation of P. aduncum and P. hispidinervum shoots. In vitro cultures maintained at 20°C on MS medium showed 100% survival with slow-growth shoots. The presence of mannitol or ABA, in the culture medium, negatively affected shoot growth, which is evidenced by the low rate of recovered shoots
Liquid extraction of noble metal ions with an α-amino phosphonate
The extraction of Au(III), Pt(IV), and Pd(II) ions from aqueous hydrochloric acid solutions with solutions of bis(2-ethylhexyl) N-butyl-N-octylaminomethylphosphonate in chloroform and xylene was studied. The recovery of the noble metal ions is the most efficient at low acidities of the aqueous solution, with a high selectivity of separation from the concomitant Fe(III), Cu(II), Ni(II), and Co(II) ions. © 2005 Pleiades Publishing, Inc
Three-dimensional structure of phosphorus-containing heterocycles - II. Dipole moments and Kerr constants of some 2-thiono-1,3,2-dioxaphosphorinanes
The three-dimensional structure of a number of 2-thiono-1,3,2-dioxaphosphorinanes was studied by means of dipole moments, the Kerr effect, and theoretical conformational analysis with P31 NMR data. 2,4-Dimethyl- and 2-chloro-2-thiono-1,3,2-dioxaphosphorinanes have the chair conformation with an equatorial thionophosphoryl group; the 2-methyl derivative exist as an equilibrium mixture of the axial and equatorial conformers with predominance of the former. The participation of the boat form in the conformational equilibrium was established for 2-chloro-4-methyl derivative. © 1974 Consultants Bureau
Synthesis and acid-base properties of α-aminophosphoryl compounds
α-Aminophosphoryl compounds of the phosphonate, phosphine oxide, and α,ω-bis(phosphine oxide) series and some of their thiophosphoryl analogs were synthesized. Potentiometric measurements of the pK a of the conjugate acids revealed an insignificant effect of variation of substituents on the phosphorus, nitrogen, and α-carbon atoms on the basicity of the phosphorylated amines. The latter are weak bases. Organophosphorus groups decrease the basicity of the amines by almost 5 pK a units. The role of the hydrophobic effect and intramolecular H-bonding in the obtained substances was discussed
Synthesis and complexing properties of N-(thio)phosphorylated bis(thio)ureas
New phosphorus-containing podands, N-(thio)phosphorylated bis(thio)ureas, were prepared by reactions of α,ω-diamines with (thio)phosphoryl iso(thio)cyanates. Chelates of these compounds with some metal ions were isolated
Experience in Genome Analysis Use in SAET Mobile Complex Facilities
Described is the first-ever experience in genome analysis use in SAET mobile complex facilities, obtained during the XXVII World-wide Summer Universiade in Kazan, 2013. Carried out was 16S rRNA sequencing of Salmonella enteric strain isolated from an infected. For that matter, employed was “MicroSEQ 500 16S rDNA Bacterial Identification Kits” (Applied Biosystems, USA), which allows for sequencing of DNA fragments (500 bp) of 16S rRNA gene in the bacteria under investigation
Effects of age and gender on dietary habits of people engaged in sports at the age of 40 and older
Objective: to analyze how eating habits depend on age and gender among people aged 40 and over engaged in sports (athletics, participation in 10 km or more road running races).Materials and methods: the information about eating habits was obtained through questionnaires of athletes aged 40 and over, participating in 10 km or more road running races. 1649 questionnaires were analyzed. The analysis was carried out in three age groups: 40–49 years old, 50–59 years old, and 60 years old and over.Results: more than half of men and a third of women do not follow any principles in organizing their diet. The most common habit, regardless of gender, is eating three or more times a day. The largest amount of food is consumed in the middle of the day and in the afternoon. Most of the respondents try to eat at the same time of the day, when there is such an opportunity. Snacking between main meals is a widespread habit, especially among women. Despite the fact that the majority of men and 30 % of women often consume flour products and products containing sugar, they are not overweight.Conclusion: most of the athletes aged 40 and over do not aim to follow a diet or improve nutrition
Effect of the medium on the acid-base properties of α-aminophosphoryl compounds
Structural thermodynamic analysis of the acidity of α-aminophosphoryl compounds in water-isopropanol systems was carried out by means of evaluation of the Gibbs energies of transfer of species involved in protolytic equilibria. Protonated (deprotonated) forms of structurally diverse aminophosphoryl compounds similarly interact by the mechanism of specific and universal solvation with each of the water-isopropanol solvents (100, 50, and 25 vol % of water) in the reaction series used. For this reason, there are significant linear correlations between acidity parameters for various media, which makes possible successful predictions of the acid-base properties of structurally diverse compounds of the class studied in water-isopropanol media with various water contents. © 2005 Pleiades Publishing, Inc
