Optical study of the polar BM CrB in low accretion state

This paper presents a spectral and photometric study of the poorly studied polar BM CrB. Three states of the polar brightness and signs of transition from one-pole to two-pole accretion mode were found by an analysis of ZTF data. It is shown that the transition from the low state to the high state changes the longitude of the main accretion spot (by $\approx 17^{\circ}$) and increases its elongation (by $\approx 10^{\circ}$). The spectra contain Zeeman absorptions of the H$\alpha$ line which are formed at a magnetic field strength of $15.5\pm1$ MG. These absorptions are likely produced by a cold halo extending from the accretion spot at $\approx {^1/_4}$ of the white dwarf radius. Modeling of the behavior of the H$\alpha$ emission line shows that the main source of emission is the part of the accretion stream near the Lagrangian point L$_1$, which is periodically eclipsed by the donor star. The spectra exhibit a cyclotron component formed in the accretion spot. Its modeling by a simple accretion spot model gives constraints on the magnetic field strength $B=15-40$ MG and the temperature $T_e\gtrsim15$ keV

ПРИМЕНЕНИЕ ХЕМОМЕТРИЧЕСКИХ АЛГОРИТМОВ В СПЕКТРОФОТОМЕТРИЧЕСКОМ АНАЛИЗЕ СМЕСЕЙ АНАЛИТОВ С ПОДОБНЫМИ СПЕКТРАМИ ПОГЛОЩЕНИЯ

Spectrophotometry in combination with chemometric algorithms can be applied for the analysis of mixtures with similar spectral characteristics. The methods of multiple linear regression are recommended to use in analysis of 2 or 3 component mixtures, with the increasing number of analytes it is advisable to use the method of projection to latent structures (PLS). The optimum amount of training samples to construct the PLS - calibration which can determine the components with errors of less than 10-15% was established.Keywords: method of multiple linear regression, method of projection to latent structures, similar absorption spectra(Russian)DOI: http://dx.doi.org/10.15826/analitika.2013.17.3.010P.A.

Reactive magnetron plasma modification of electrospun PLLA scaffolds with incorporated chloramphenicol for controlled drug release

Surface modification with the plasma of the direct current reactive magnetron sputtering has demonstrated its efficacy as a tool for enhancing the biocompatibility of polymeric electrospun scaffolds. Improvement of the surface wettability of materials with water, as well as the formation of active chemical bonds in the near-surface layers, are the main reasons for the described effect. These surface effects are also known to increase the release rate of drugs incorporated in fibers. Herein, we investigated the effect of plasma modification on the chloramphenicol release from electrospun poly (lactic acid) fibrous scaffolds. Scaffolds with high—50 wt./wt.%—drug content were obtained. It was shown that plasma modification leads to an increase in the drug release rate and drug diffusion coefficient, while not deteriorating surface morphology and mechanical properties of scaffolds. The materials’ antibacterial activity was observed to increase in the first day of the experiment, while remaining on the same level as the unmodified group during the next six days. The proposed technique for modifying the surface of scaffolds will be useful for obtaining drug delivery systems with controlled accelerated release, which can expand the possibilities of local applications of antibiotics and other drugs

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

Controlled drug release from electrospun PCL non-woven scaffolds via multi-layering and e-beam treatment

Currently, electrospun synthetic bioresorbable polymer scaffolds are applied in regenerative medicine and tissue engineering as targeted drug delivery devices because of their mechanical and physico-chemical properties. To control the rate of polymer degradation and drug release from polymer scaffolds, surface modification techniques are widely used. In this study, paracetamol-loaded poly (ε-caprolactone) electrospun fibrous scaffolds were treated by the pulsed electron beam irradiation. Pure control PCL scaffold, as well as scaffolds with four paracetamol concentrations (2 wt./wt. %, 8 wt./wt. %, 16 wt./wt. %, and 32 wt./wt.%) were modified. The mechanical and chemical properties and morphology of modified materials were examined. The sustained release of the model drug over a period of one hour for both non-treated and treated samples was demonstrated. It was shown that treatment leads to an increase in drug release rate and does not change surface morphology of scaffolds and fibers diameter distribution

Analysis of fundamental parameters for V477 Lyr

We analyze the photometric and spectroscopic observations of the young pre-cataclysmic variable (pre-CV) V477 Lyr. The masses of both binary components have been corrected by analyzing their radial velocity curves. We show that agreement between the theoretical and observed light curves of the object is possible for several sets of its physical parameters corresponding to the chosen temperature of the primary component. The final parameters of V477 Lyr have been established by comparing observational data with evolutionary tracks for planetary nebula nuclei. The derived effective temperature of the O subdwarf is higher than that estimated by analyzing the object's ultraviolet spectra by more than 10000 K. This is in agreement with the analogous results obtained previously for the young pre-CVs V664 Cas and UU Sge. The secondary component of V477 Lyr has been proven to have a more than 25-fold luminosity excess compared to main-sequence stars of similar mass. Comparison of the physical parameters for the cool stars in young pre-CVs indicates that their luminosities do not correlate with the masses of the objects. The observed luminosity excesses in such stars show a close correlation with the post-common-envelope lifetime of the systems and should be investigated within the framework of the theory of their relaxation to the state of main-sequence stars. © 2008 Pleiades Publishing, Ltd
