We analyze the results of studies on predicting professional success of Security Departments Officers of penitentiary institutions and pretrial detention centers, and on socio-psychological climate ...in security units (2062 employees of eighteen territorial bodies of the Federal Penitentiary Service of Russia), as well as diagnosis and correction of borderline mental state of employees of these units (372 employees from four regional offices of the Federal Penitentiary Service of Russia). We describe the criteria for determining the psychological suitability to guardian activity in the context of penal system. Using “Questionnaire of social and psychological climate in special divisions of the correctional system in Russia”, we proposed a complex of measures aimed at optimizing the social and psychological climate in the security departments of penitentiary and detention facilities. The application of science based and experimentally tested diagnostic and corrective complex, we recommended a technology for short-term correction of borderline mental states in employees of these units.
The promoter of the Escherichia coli udp gene contains the poly-T (5'-TTTTT-3') motif in the transcription start region located at the distance of 3 nucleotides with respect to the Pribnow box. By ...means of site-directed mutagenesis, mutations in the +1, -1, and +3 positions of this region were isolated and their functional role in transcription initiation was determined. It was shown that in addition to the thymine nucleotide earlier identified at position 4 (with respect to the 5' end of the poly-T motif), the third thymine nucleotide may serve as an efficient transcription site. The functional significance of the presence of the poly-T motif in the transcription initiation region is discussed. Analysis of the isolated mutant promoters revealed the ability of the guanine nucleotide at the +3 position to stabilize the formation of a productive transcription complex and to serve as an additional transcription start.
A measurement is presented of the tt inclusive production cross section in pp collisions at a center-of-mass energy of radicals = 8 TeV using data collected by the ATLAS detector at the CERN Large ...Hadron Collider. The measurement was performed in the lepton + jets final state using a data set corresponding to an integrated luminosity of 20.3 fb super(-1). The cross section was obtained using a likelihood discriminant fit and b-jet identification was used to improve the signal-to-background ratio. The inclusive tt production cross section was measured to be 260 + or - 1(ProQuest: Formulae and/or non-USASCII text omitted)(stat) + or - 8(lumi) + or - 4(beam) pb assuming a top-quark mass of 172.5 GeV, in good agreement with the theoretical prediction of (ProQuest: Formulae and/or non-USASCII text omitted) pb. The tt arrow right (e, u) + jets production cross section in the fiducial region determined by the detector acceptance is also reported.
Effect of mutations in the -10 and -35 regions of the udp gene promoter on the nature of its regulation by CytR and CRP proteins was studied. In studies of expression of mutant promoters, competition ...between RNA polymerase and the CytR repressor for the promoter region of the udp gene was shown. In the presence of the improved -10 region, the introduction of a substitution 15C-->T (that is the presence of the elongated Pribnow block) resulted in the CRP-independent transcription of the udp gene promoter. The binding site CRP2 was shown to be indispensable for the maximum promoter activation by the transcription-activating cAMP-CRP complex. Both positive (cAMP-CRP complex) and negative (CytR) regulation of the promoter was virtually fully abolished after the introduction of mutations leading to the creation of canonical sequences in -10 and -35 promoter regions.
