Laser Separation

One challenge for volume manufacturing of 4H-SiC devices is the state-of-the-art wafer dicing technology – the mechanical blade dicing which suffers from high tool wear and low feed rates. In this paper we discuss Thermal Laser Separation (TLS) as a novel dicing technology for large scale production of SiC devices. We compare the latest TLS experimental data resulting from fully processed 4H-SiC wafers with results obtained by mechanical dicing technology. Especially typical product relevant features like process control monitoring (PCM) structures and backside metallization, quality of diced SiC-devices as well as productivity are considered. It could be shown that with feed rates up to two orders of magnitude higher than state-of-the-art, no tool wear and high quality of diced chips, TLS has a very promising potential to fulfill the demands of volume manufacturing of 4H-SiC devices.

Children’s socialisation centres that have been operating since 2008 execute a double mission, i.e. they provide comprehensive education and ensure supervision as well as re-socialisation of delinquent juveniles. High-quality implementation of the integrated mission of children’s socialisation centres is mostly determined by strategic management of these institutions. Results of the survey of administration representatives and other staff of chil-dren’s socialisation centres carried out from November 2012 through February 2013 re-vealed that all groups’ employees of children’s socialisation centres positively assessed stra-tegic management of their institutions and also acknowledged the demand for its perfection. Statistically significant differences in assessment of strategic management of children’s so-cialisation centres and the need for its improvement in separate groups of respondents have been found out. The most visible differences concerning assessment of strategic manage-ment of children’s socialisation centres have been estimated among representatives of ad-ministrative staff and class tutors that took part in the survey. Respondents’ opinions mostly differed concerning the need to improve the incentive system for staff, the changes in the objective policy concerning staff selection and constant care of the administration about social and psychological safety of employees. It has been found out that respondents’ so-cio-demographic variables (sex, age, duration of employment, work experience in other insti-tutions) make a low statistically significant impact on assessment of the need for strategic management of children’s socialisation centres and its improvement. When assessing strate-gic management of children’s socialisation centres, administrative staff are mostly sure that they promote and implement changes in culture of children’s socialisation centres, give prior-ity to high-quality implementation of the purpose of children’s socialisation centres, ensure accessibility to information necessary for employees, maintain matter-of-fact relationships and constant dialogue with staff, regard their opinions when making decisions; however, they agree that these areas of strategic management of children’s socialisation centres should be perfected. It is proved by participated administrative staff who are focused on constant improvement of management processes, even though they are not completely convinced that they constantly develop their managerial competences which are a very im-portant precondition for qualitative changes in management processes. It has been found out that class tutors at children’s socialisation centres, even though positively assessing strategic management of their institutions, are more critical about such areas of strategic management, in comparison to another group of respondents: human re-sources management, complex planning of performance of children’s socialisation centre and involvement of employees into planning processes, distribution of functions and re-sponsibilities of staff, assessment of quality of activities of employees and the making of important decisions concerning its improvement, etc. First of all, class tutors relate the changes in quality of strategic management of children’s socialisation centres with the area of human resources management. Some one fifth of class tutors that took part in the survey agree that administration of their institutions have a clear strategy of development of the children’s socialisation centre and treat high-quality implementation of the purpose of chil-dren’s socialisation centres as the major aim. Pedagogues of children’s socialisation centres who took part in the research positively assess strategic management of their institutions; nevertheless, they are more sure about effectiveness of some of strategic management areas than their colleagues do, and more tend to suppose that there is no need to improve such areas of institutional management as creation of positive psychological climate, stimulation of collaboration among employees, strategic planning of performance of the centre, involvement of employees into such pro-cesses, orientation towards the priority aim, i.e. quality of performance of the children’s so-cialisation centre, stimulation of changes in culture of children’s socialisation centres, as-sessment of quality of activities of employees, etc. It is likely that pedagogues do not treat quality of various activities, processes, management of children’s socialisation centres as a finite process. Expression of assessment of strategic management of children’s socialisation centres and the demand for its expression demonstrates that managerial potential is not maximally used to implement qualitative changes in the purpose of children’s socialisation centres. Key words: children’s socialisation centre, strategic management, assessment of strategic management.

The results of an experimental study of liquid fuel flows in the tanks of a spacecraft during its rotation are presented. The analysis of structure and character of flows development on time is carried out, variants of graphic dependences approximation are offered. Graphical diagrams are presented, according to which it is convenient to present a three-dimensional nonlinear picture of non-stationary axisymmetric flow in a spherical reservoir, as well as methods of influencing flows with the help of internal baffles. Estimation of the obtained experimental data probability testifies to the rather high quality of the measurement results and the constructed picture of the currents in the spherical tank with internal baffles.

The paper explores the painted ornament of the Holy Trinity chapel at the monastery of Saint John Chrysostom Koutsovend?s in Cyprus, founded by Eumathios Philokal?s (ca. 1100). When compared to that of other early Komnenian monuments on the island, the painted ornament at Holy Trinity stands out for its intricacy, diversity, and high-quality of execution, while its sophistication is demonstrated to be in keeping with the ambitious and erudite character of the painted ensemble as a whole. Not least, rather than being on the fringe, the painted ornament appears to have been fully integrated into the iconographic programme of the chapel, reiterating through metaphor the patron?s hope for salvation.

A number of environmentally hazardous substances are used in the process of flax roving preparation for spinning. An alternative to them can be the use of electrochemical activated aqueous solutions. However, the metastability of such solutions requires time tracking of their properties’ relaxation. This article pre-sents experimental data on the relaxation of relevant solutions that can be used for a well-founded selection of flax roving treatment procedures to ensure a re-quired quality of flax yarn. It has been experimentally proven that the use of ECA solutions for preparing rovings for spinning allows to obtain high quality yarn as well as significantly reduce wastewater pollution and improve the envi-ronmental situation in the places of their emissions.

Continuously Cast

Free-cutting steel gains specific working properties thanks to the high content of sulfur and phosphorus. These elements, especially sulfur, have a rather high tendency to segregation. Therefore, segregation defects in free-cutting steel continuously cast billets can be significantly developed. The aim of the work was to study the influence of the chemical composition of freecutting steel and casting technological parameters on the quality of the macrostructure of continuously cast billets. A metallographic assessment of the internal structure of cast metal made of free-cutting steel and data processing by application of correlation and regression analysis were the research methods. The array of production data of 43 heats of free-cutting steel of grade A12 was studied. Steel casting on a five-strand radial type continuous casting machine was carried out by various methods of metal pouring from tundish into the molds. Metal of 19 heats was poured with an open stream, and 24 heats – by a closed stream through submerged nozzles with a vertical hole. High-quality billets had a cross-sectional size of 150×150 mm. The macrostructure of high-quality square billets made of free-cutting steel of A12 grade is characterized by the presence of central porosity, axial segregation and peripheral point contamination, the degree of development of which was in the range from 1.5 to 2.0 points, segregation cracks and strips – about 1.0 points. In the course of casting with an open stream, almost all of these defects are more developed comparing with the casting by a closed stream. As a result of correlation and regression analysis, linear dependences of the development degree of segregation cracks and strips both axial and angular on the sulfur content in steel and on the ratio of manganese content to sulfur content were established. The degree of these defects development increases with growing of sulfur content in steel of A12 grade. These defects had especially strong development when sulfur content in steel was of more than 0.10%. To improve the quality of cast metal, it is necessary to have the ratio of the manganese content to the sulfur content in the metal more than eight.

Methodological Aspects

The transthoracic echocardiography made by multifrequency probes with support of the mode of the second harmonic imaging, is a competitive method for visualization of the main coronary arteries and allows to estimate coronary blood flow with high quality. Of course, the method has considerable restrictions, most important of which is the low spatial resolution of a method, due to small acoustic window. Because of this the transthoracic visualization of coronary arteries perhaps will not become the leading method of anatomic reconstruction of separately taken coronary artery and especially all coronary arteries system. However uniqueness and indisputable advantage of this method is an opportunity to noninvasively estimate a coronary blood flow both once, and in dynamics.
