Haydn composed this mass for the Benedictine convent of Frauenwörth on Chiemsee. Completed on 5 August 1793, the work was probably intended for the service accompanying the taking of final vows on 19 August 1793 by the composer's friend Ursula Oswald. This mass represents Haydn's late style, in which a large-scale cyclic unity is achieved through the ongoing transformation and recall of thematic materials among its several movements.

Background. The aim of the article is examination and presentation of Valentyn Borysov’s creative life, who was a celebrated Ukrainian composer (1901–1988), a classic of Kharkiv composition school, author of vivid and profound works in such spheres as symphonic, choral, chamber, vocal and piano music; his 120th anniversary in 2021 will be a big milestone for artistic community of Ukraine. Valentyn Borysov’s creativity is an indispensable part of national music, one of its treasures. He belonged to artists who had defined ways of development of Ukrainian professional music in XX century. In his creative outcome we can see influences of numerous artistic tendencies, characteristic for extremely controversial, but also prolific epoch. Composer being a part of quite ambivalent period of Ukraine’s cultural history conditioned usage of diverse research approaches; his works are regarded both in the light of existing musical traditions and on the background of his contemporary cultural environment. This is the novelty of the study. Integrity of presentation of Valentyn Borysov’s creative life is supported by the fact that this article considers his pedagogical activity in his alma mater, nowadays Kharkiv I. P. Kotlyarevsky National University of Arts, which resulted in bringing up a constellation of well-known Ukrainian composers, as well as his public and aimed at cultural enlightenment work. Results and conclusions. For V. Borysov, stage of accumulation of professional and personal experience coincided in time with a turning point in development of Ukrainian musical art. In these years composer attended classes of S. S. Bogatyrov, forefather of Kharkiv composition school; he studied alongside with M. Koliada, H. Tumeneva, D. Klebanov, V. Barabashov, M. Tits, who constituted a brilliant generation of Ukrainian composers several decades later. Symphonic and chamber works of this time showed such features of V. Borysov’s creative method as large-scale thought, leaning towards epic and heroic images, skilful usage of advanced composition techniques. At the same time, under the influence of external factors V. Borysov turned to relevant genre of his time, such as mass song and choral music. As early as on the primary stage of his development as a composer, V. Borysov defined Ukrainian folklore as one of the main sources for his inspiration. Folklore component of musical language became one of the prominent features of his style, its presence is conspicuous on each stages of his evolution. Submission of individual to collective, national conditioned V. Borysov’s interest to monumental forms of symphony, oratorio, cantata, poem, defined their leading role through late style of composer’s creativity. Unique combination of already existing aesthetic premises, high level of moral imperative, relevance of musical language created phenomenon of “V. Borysov’s late style”. The article regards the most original works, which were received very well by the contemporaries: “Divertissement” for symphonic orchestra, “Music for strings”, concert compositions for piano, violin, viola, sets of piano miniatures, composed on late period (70s–80s). Singularity of musical language in these works is created by the fact that V. Borysov succeeded to create a unique mixture of folklore tradition with “sonic field” of avantgarde musical art; with this musical language incredibly relevant, “eternal” problems of existence are embodied. This article was inspired by a desire to draw attention to V. Borysov’s legacy, to revive profound and immensely talented works of the composer, to enrich culture of modernity with them, to remind people of XXI century about such a treasure, that his works are.

AbstractUnusual short-period comet 29P/Schwassmann-Wachmann 1 inspired many observers to explain its unpredictable outbursts. In this paper large scale structures and features from the inner part of the coma in time periods around outbursts are studied. CCD images were taken at Whipple Observatory, Mt. Hopkins, in 1989 and at Astronomical Observatory, Modra, from 1995 to 1998. Photographic plates of the comet were taken at Harvard College Observatory, Oak Ridge, from 1974 to 1982. The latter were digitized at first to apply the same techniques of image processing for optimizing the visibility of features in the coma during outbursts. Outbursts and coma structures show various shapes.

AbstractThe large-scale coronal structures observed during the sporadically visible solar eclipses were compared with the numerically extrapolated field-line structures of coronal magnetic field. A characteristic relationship between the observed structures of coronal plasma and the magnetic field line configurations was determined. The long-term evolution of large scale coronal structures inferred from photospheric magnetic observations in the course of 11- and 22-year solar cycles is described.Some known parameters, such as the source surface radius, or coronal rotation rate are discussed and actually interpreted. A relation between the large-scale photospheric magnetic field evolution and the coronal structure rearrangement is demonstrated.

AbstractPrecise measurements of heliographic position of solar filaments were used for determination of the proper motion of solar filaments on the time-scale of days. The filaments have a tendency to make a shaking or waving of the external structure and to make a general movement of whole filament body, coinciding with the transport of the magnetic flux in the photosphere. The velocity scatter of individual measured points is about one order higher than the accuracy of measurements.

Trends in the technology development of very large scale integrated circuits (VLSI) have been in the direction of higher density of components with smaller dimensions. The scaling down of device dimensions has been not only laterally but also in depth. Such efforts in miniaturization bring with them new developments in materials and processing. Successful implementation of these efforts is, to a large extent, dependent on the proper understanding of the material properties, process technologies and reliability issues, through adequate analytical studies. The analytical instrumentation technology has, fortunately, kept pace with the basic requirements of devices with lateral dimensions in the micron/ submicron range and depths of the order of nonometers. Often, newer analytical techniques have emerged or the more conventional techniques have been adapted to meet the more stringent requirements. As such, a variety of analytical techniques are available today to aid an analyst in the efforts of VLSI process evaluation. Generally such analytical efforts are divided into the characterization of materials, evaluation of processing steps and the analysis of failures.

Titanium nitride (TiN) films have historically been used as diffusion barrier between silicon and aluminum, as an adhesion layer for tungsten deposition and as an interconnect material etc. Recently, the role of TiN films as contact barriers in very large scale silicon integrated circuits (VLSI) has been extensively studied. TiN films have resistivities on the order of 20μ Ω-cm which is much lower than that of titanium (nearly 66μ Ω-cm). Deposited TiN films show resistivities which vary from 20 to 100μ Ω-cm depending upon the type of deposition and process conditions. TiNx is known to have a NaCl type crystal structure for a wide range of compositions. Change in color from metallic luster to gold reflects the stabilization of the TiNx (FCC) phase over the close packed Ti(N) hexagonal phase. It was found that TiN (1:1) ideal composition with the FCC (NaCl-type) structure gives the best electrical property.

Copper-based metallization has recently attracted extensive research because of its potential application in ultra-large-scale integration (ULSI) of semiconductor devices. The feasibility of copper metallization is, however, limited due to its thermal stability issues. In order to utilize copper in metallization systems diffusion barriers such as titanium nitride and other refractory materials, have been employed to enhance the thermal stability of copper. Titanium nitride layers can be formed by annealing Cu(Ti) alloy film evaporated on thermally grown SiO2 substrates in an ammonia ambient. We report here the microstructural evolution of Cu(Ti)/SiO2 layers during annealing in NH3 flowing ambient.The Cu(Ti) films used in this experiment were prepared by electron beam evaporation onto thermally grown SiO2 substrates. The nominal composition of the Cu(Ti) alloy was Cu73Ti27. Thermal treatments were conducted in NH3 flowing ambient for 30 minutes at temperatures ranging from 450°C to 650°C. Cross-section TEM specimens were prepared by the standard procedure.

CMP-KDO synthetase (CKS) is an enzyme which plays a key role in the synthesis of LPS, an outer membrane component unique to gram negative bacteria. CKS activates KDO to CMP-KDO for incorporation into LPS. The enzyme is normally present in low concentrations (0.02% of total cell protein) which makes it difficult to perform large scale isolation and purification. Recently, the gene for CKS from E. coli was cloned and various recombinant DNA constructs overproducing CKS several thousandfold (unpublished data) were derived. Interestingly, no cytoplasmic inclusions of overproduced CKS were observed by EM (Fig. 1) which is in contrast to other reports of large proteinaceous inclusion bodies in various overproducing recombinant strains. The present immunocytochemical study was undertaken to localize CKS in these cells.Immune labeling conditions were first optimized using a previously described cell-free test system. Briefly, this involves soaking small blocks of polymerized bovine serum albumin in purified CKS antigen and subjecting them to various fixation, embedding and immunochemical conditions.
