Published: January 2017

Abstract
Integrated monitoring system for discrete manufacturing processes is presented in the paper. The multilayer hardware and software reference model was developed. Original research are an answer for industry needs of the integration of information flow in production process. Reference model corresponds with proposed data model based on multilayer data tree allowing to describe orders, products, processes and save monitoring data. Elaborated models were implemented in the integrated monitoring system demonstrator developed in the project. It was built on the base of multiagent technology to assure high flexibility and openness on applying intelligent algorithms for data processing. Currently on the base of achieved experience an application integrated monitoring system for real production system is developed. In the article the main problems of monitoring integration are presented, including specificity of discrete production, data processing and future application of Cyber-Physical-Systems. Development of manufacturing systems is based more and more on taking an advantage of applying intelligent solutions into machine and production process control and monitoring. Connection of technical systems, machine tools and manufacturing processes monitoring with advanced information processing seems to be one of the most important areas of near future development. It will play important role in efficient operation and competitiveness of the whole production system. It is also important area of applying in the future Cyber-Physical-Systems that can radically improve functionally of monitoring systems and reduce the cost of its implementation.

Published: January 2017

AbstractMycobacterium tuberculosis (Mtb) can persist in the human host in a latent state for decades, in part because it has the ability to withstand numerous stresses imposed by host immunity. Prior studies have established the essentiality of the periplasmic protease MarP for Mtb to survive in acidified phagosomes and establish and maintain infection in mice. However, the proteolytic substrates of MarP that mediate these phenotypes were unknown. Here, we used biochemical methods coupled with supravital chemical probes that facilitate imaging of nascent peptidoglycan to demonstrate that during acid stress MarP cleaves the peptidoglycan hydrolase RipA, a process required for RipA's activation. Failure of RipA processing in MarP‐deficient cells leads to cell elongation and chain formation, a hallmark of progeny cell separation arrest. Our results suggest that sustaining peptidoglycan hydrolysis, a process required for cell elongation, separation of progeny cells, and cell wall homeostasis in growing cells, may also be essential for Mtb's survival in acidic conditions.

Published: January 2017

In paper the features of energy transformation processes in activated with erbium ions laser materials based on optical transitions in 4f shell of Er3+ ionwere discussed. Methods of excitation of the luminescence in chalcogenide glasses doped with Er3+ ions were described and found how its intensity depends on concentration of the ions. Up-conversion and cross-relaxation play an important role in the transformation of excitations in erbium-doped materials. In cross-relaxation the energy of one center can be nonradiatively transferred to another center or divided between the two centers, while in the up-conversion, however, energy of several centers summed up in one center, bringing it acts as an additional channel of luminescence quenching, or as a way of pumping of the higher energy levels. To improve the efficiency of optical excitation of many laser materials doped with erbium ions the sensitization with ytterbium ions that have intense absorption band in the range of ~0.9-1 µm with "effective" width of about 1000 cm-1 as well a channel of the efficient nonradiative excitation energy transfer to Er3+ ions is widely used.

Published: January 2017

Advanced integrated logic circuits on GaAs are mainly based on the using of n-channel field-effect transistors with gate Schottky (MESFET). To create the complementary MESFET integrated circuits the main problem is quite small Schottky barrier height (< 0,5 eV) on p-type gallium arsenide. One way to solve this problem is to use a nitride or silicide tungsten compounds to form gates given the thickness and composition.
This paper highlights the features of the formation of complementary high-speed logic circuits on the p-GaAs with self-aligned gate based on nitride or silicide of tungsten obtained by reduced pressure horizontal reactor "Izotron 4" and of RF magnetron sputtering equipment "Oratorio-5." This technology can also be used to form a Schottky contact to n- channel MESFET.
Since the manufacturing process of MESFET self-aligned gate provides using refractory gate material as a mask for the multiply ion implantation, the Schottky contact must withstand subsequent high-temperature heat treatment required to activate implanted impurities. In this connection, the action of high-temperature photonic and resistive heating on the barrier height of Schottky contact formed by nitride (silicide) tungsten (WNx, WSix) GaAs was also studied.

The changes of the structure of morphology are confirmed by the redistribution of valence Ор-, Sisd- та Alsd electrons mixtures as a result of mechanical activation.
Structural Fragments Izopolivolframat–Anions and Gibbs Energy of Formation
Authors: Rozantsev G.M. 
Published: January 2017

The method of mathematical modeling (program CLINP 2.1, Newton's method) on the basis of the pH-potentiometric titration data allowed to calculate concentration constants of isopolytungstate anions (IPTA) formation at different ionic forces (I = 0,01 ‑ 0,5 M). Thermodynamic constants of IPTA formation were obtained as a result of processing by Pitzer method using the concentration constans. The standard Gibbs energy of isopolytungstate anions formation were calculated. The last ones allowed to estimate the thermodynamic probability of the reactions, that can be used in the synthesis of salts containing these anions. The structure of known isopolytungstates can be built from the combination of such fragments: WO, W2O, W3O, W4O and W5O. The calculation of standard Gibbs energy of these fragments formation allowed to characterize the structure of hexatungstate-anion W6O20(OH)26-, which does not contain three terminal oxygen atoms. Such approach of using Gibbs energy of building blocks was recommended for prediction of equilibrium constants values in the mathematical modeling.

We investigated the processes of water absorption, chemical stability and microhardness of films of epoxy composites that contained as the polymer matrix the epoxy resin UP-655 and mineral fillers: graphite, mica, aluminum oxide at their content (0 - 30 % mass). It found that introduction of mineral fillers significantly affects on all complex of operating characteristics of the films. Increase of filler content, especially mica, to 20 %, resulting in slower process and reducing the quantity of absorbed moisture by films. In the study of physical and mechanical properties of filled epoxy composites was established that the introduction of mineral filler significantly affects their microhardness, and the nature of the exposure is determined by the type and filler content.

AbstractInterpersonal communication represents one of the most important aspects in the process of education. Its role may be seen at multiple levels. It can also be considered as a generator of interpersonal relations in the educational process as well as a consequence of the established interpersonal relations at the subject level in the educational process. In other words, interpersonal communication ensures generation of the social matrix within which education takes place in a broad sense and immediate educational process in a more restricted sense. Therefore, the study of interpersonal communication is of crucial importance for understanding and improving education as a whole. The analysis and systematisation of research directions of interpersonal communication in education have been conducted for the purpose of this paper with the aim of providing a systematic insight into the mentioned issues, and also ensuring the platform for further research.Key words: conversation at school; educational process; pedagogical communication. --- SažetakInterpersonalna komunikacija predstavlja jedan od najvažnijih aspekata u procesu edukacije. Njezina uloga očituje se na više razina, pa ju je moguće promatrati kao generator interpersonalnih odnosa u odgojno-obrazovnom procesu, ali i kao posljedicu uspostavljenih interpersonalnih odnosa na razini subjekata edukacijskog procesa. Drugim riječima, interpersonalna komunikacija osigurava generiranje socijalne matrice unutar koje se odvija edukacija u širem, odnosno neposredan odgojno-obrazovni rad u užem smislu. Stoga je izučavanje interpersonalne komunikacije od iznimne važnosti za razumijevanje i unaprjeđenje edukacije u cjelini.

<p>La importancia de la educación hace evidente que se considere educar en Cambio Climático a los estudiantes. El propósito principal de este estudio fue examinar la interpretación de cambio climático en infografías de estudiantes de educación superior y explorar el conocimiento de los estudiantes a base de cambios climáticos. Para el logro del propósito se realizó un análisis de contenido para analizar las infografías que presentan los estudiantes antes (diagnóstico) y después (formativo) de integrar con un currículo oculto conceptos de cambio climático en un curso de Biología General. El estudio que se llevó a cabo fue de carácter cualitativo con un enfoque de análisis de contenido. La muestra estuvo conformada por estudiantes de una institución de educación superior de Puerto Rico que tomaron un curso de Biología General.</p><p>Los resultados del análisis de contenido reflejaron que el 81% de los estudiantes tuvo algún concepto erróneo de cambio climático al comienzo del curso. Luego, de ofrecer el curso de Biología General e integrar conceptos de cambio climático con un currículo oculto, los estudiantes minimizaron sus conceptos erróneos a un 9%. Por tanto, se concluye que se deben integrar conceptos de cambio climático en los cursos de Ciencias para lograr una mejor Educación Ambiental. Esto explica que existe una necesidad por educar a los estudiantes en cambio climático como recomiendan las agencias estatales e internaciones. Entonces, se afirma que se debe considerar el potencial de las universidades para desarrollar la Educación Ambiental y establecer una colaboración estrecha entre las distintas instituciones de educación superior como bien lo estableció la Organización de las Naciones Unidas para la Educación, la Ciencia y la Cultura (UNESCO, por sus siglas en inglés)</p><p> </p>

Background: Diabetes mellitus (DM) refers to a group of common metabolic disorders that share the phenotype of hyperglycaemia. The metabolic dysregulations associated with DM causes secondary pathophysiological changes in multiple organ systems which result in various complications, responsible for the morbidity and mortality associated with the disease.Methods: The present study was undertaken in the Department of Medicine in collaboration with the Department of Biochemistry, of SGRDIMSR, Vallah, Sri Amritsar, Punjab, India. The present hospital based study was undertaken with a total number of 100 patients.Results: The mean Cystatin C values in Group A were 1.73 and mean Cystatin C values in group B were 2.07. The results show that the Cystatin C values were raised even in the patients in whom clinical albuminuria had not yet started.Conclusions: serum Cystatin C may be considered as an early marker, than microalbuminuria and serum creatinine, the commonly used marker for nephropathy, for declining renal function, in diabetic subjects. Further studies in larger population are needed to confirm this result.
