AI MENTORING AS A FORM AKMEOLOGICHESKOJ ORIENTED PROFESSIONAL INTERACTION

Optimization of professional relationships in the "mentor- apprentice" promotes the formation of a professional orientation akmeologicheskoj both subjects interaction. On the one hand , mentoring is one of the oldest and most effective ways to acquire knowledge and skills of young employees of the company in the process of adapting to a new team . On the other - allows teacher to identify their professional and personal opportunities and consciously decide to choose the optimum time of interaction with the students, based on their individual characteristics, as well as improve their own skills.Оптимизация профессиональных взаимоотношений в системе «наставник – ученик» способствует формированию акмеологической профессиональной направленности у обоих субъектов взаимодействия. Наставничество является одним из самых старых и эффективных способов приобретения знаний и навыков молодыми сотрудниками предприятия в процессе их адаптации в новом коллективе; позволяет наставнику выявить свои профессионально-личностные возможности и осознанно определиться в выборе оптимального стажа взаимодействия с учениками, с учетом их индивидуальных особенностей, а также повысить уровень собственного мастерства

Selection of cultivation medium for production of late stationary phase serine proteinases from Bacillus intermedius

B. intermedius have been shown previously to secrete two serine proteinases: glutamyl endopeptidase 2 and subtilisin 2 during the late stationary phase, with maximal levels of the enzymes activities recorded at the 40th and 44th hours of growth, respectively. In the current study, we analyzed the impact of various culture medium components on biosynthesis of these proteinases. Yeast extract and gelatin did not stimulate the enzymes biosynthesis. However, on the medium containing 0.1% casein subtilisin 2 production increased to reach 140%. Biosynthesis of both serine proteinases, produced by B. intermedius at the late stationary phase, were found to be inhibited by individual amino acids, and to be insensitive to catabolite repression. In order to maximise enzyme production, the presence of Ca 2+ and Mg2+ at concentration of 5 mM was shown to be necessary. Based on the results of this work, the composition of a complex culture media for the effective production of late stationary phase proteinases by B. intermedius was developed

Picosecond Fluorescence Relaxation Spectroscopy of the Calcium-Discharged Photoproteins Aequorin and Obelin

Addition of calcium ions to the Ca2+-regulated photoproteins, such as aequorin and obelin, produces a blue bioluminescence originating from a fluorescence transition of the protein-bound product, coelenteramide. The kinetics of several transient fluorescent species of the bound coelenteramide is resolved after picosecond-laser excitation and streak camera detection. The initially formed spectral distributions at picosecond-times are broad, evidently comprised of two contributions, one at higher energy (25000 cm-1) assigned as from the Ca2+-discharged photoprotein-bound coelenteramide in its neutral state. This component decays much more rapidly (t1/2 2 ps) in the case of the Ca2+-discharged obelin than aequorin (t1/2 30 ps). The second component at lower energy shows several intermediates in the 150-500 ps times, with a final species having spectral maxima 19400 cm-1, bound to Ca2+-discharged obelin, and 21300 cm-1, bound to Ca2+-discharged aequorin, and both have a fluorescence decay lifetime of 4 ns. It is proposed that the rapid kinetics of these fluorescence transients on the picosecond time scale, correspond to times for relaxation of the protein structural environment of the binding cavit

Zebrafish Mutants calamity and catastrophe Define Critical Pathways of Gene–Nutrient Interactions in Developmental Copper Metabolism

Nutrient availability is an important environmental variable during development that has significant effects on the metabolism, health, and viability of an organism. To understand these interactions for the nutrient copper, we used a chemical genetic screen for zebrafish mutants sensitive to developmental copper deficiency. In this screen, we isolated two mutants that define subtleties of copper metabolism. The first contains a viable hypomorphic allele of atp7a and results in a loss of pigmentation when exposed to mild nutritional copper deficiency. This mutant displays incompletely penetrant skeletal defects affected by developmental copper availability. The second carries an inactivating mutation in the vacuolar ATPase that causes punctate melanocytes and embryonic lethality. This mutant, catastrophe, is sensitive to copper deprivation revealing overlap between ion metabolic pathways. Together, the two mutants illustrate the utility of chemical genetic screens in zebrafish to elucidate the interaction of nutrient availability and genetic polymorphisms in cellular metabolism

Visual-auditory volume rendering of scalar fields

Presented at the 25th International Conference on Auditory Display (ICAD 2019) 23-27 June 2019, Northumbria University, Newcastle upon Tyne, UK.This paper describes a novel approach to visual-auditory volume rendering of continuous scalar fields. The proposed method uses well-established similarities in light transfer and sound propagation modelling to extend the visual scalar field data analysis with auditory attributes. We address the visual perception limitations of existing volume rendering techniques and show that they can be handled by auditory analysis. In particular, we describe a practical application to demonstrate how the proposed approach may keep the researcher aware of the visual perception issues in colour mapping and help track and detect geometrical features and symmetry break, issues that are important in the context of interpretation of the physical phenomena
