Repertoires of tRNAs: The Couplers of Genomics and Proteomics
Authors: Rak Roni , Dahan Orna , Pilpel Yitzhak
Published: August 2018

The pool of transfer RNA (tRNA) molecules in cells allows the ribosome to decode genetic information. This repertoire of molecular decoders is positioned in the crossroad of the genome, the transcriptome, and the proteome. Omics and systems biology now allow scientists to explore the entire repertoire of tRNAs of many organisms, revealing basic exciting biology. The tRNA gene set of hundreds of species is now characterized, in addition to the tRNA genes of organelles and viruses. Genes encoding tRNAs for certain anticodon types appear in dozens of copies in a genome, while others are universally absent from any genome. Transcriptome measurement of tRNAs is challenging, but in recent years new technologies have allowed researchers to determine the dynamic expression patterns of tRNAs. These advances reveal that availability of ready-to-translate tRNA molecules is highly controlled by several transcriptional and posttranscriptional regulatory processes. This regulation shapes the proteome according to the cellular state. The tRNA pool profoundly impacts many aspects of cellular and organismal life, including protein expression level, translation accuracy, adequacy of folding, and even mRNA stability. As a result, the shape of the tRNA pool affects organismal health and may participate in causing conditions such as cancer and neurological conditions.
Taxonomic redefinition of Bupleurum pauciradiatum and B. wolffianum (Apiaceae)
Authors: STOYANOV STOYAN
Published: August 2018

Bupleurum pauciradiatum is recorded for the first time in the Balkans. It was discovered in the Kaliakra Reserve, the Bulgarian North Black Sea coast. A revised species description and comparison with its morphologically closest taxa—B. asperuloides and B. wolffianum—are given. The name B. pauciradiatum was misused in the countries of Transcaucasia for B. wolffianum. Bupleurum wolffianum is found conspecific with B. leptocladum, and the latter is reduced into synonymy. The records of B. pauciradiatum in the Crimea belong to B. asperuloides.

computations on cloud growth related to the seeding of tropical cumuli
Authors: Woodley William L.
Published: August 2018

A statistical study has been conducted investigating the possible cloud growth effects due to heat released when supercooled water is converted to ice. Calculations are made of the heights to which cloud tops would rise assuming that the supercooled water is converted to ice at − 10C (the seeded case) or at − 30C (the unseeded case). The clouds suffer a loss in buoyancy due to entrainment and the weight of the condensate. Sixty-two cases are treated for soundings from St. Martins Island during August of 1962. The results of this study are compared to those of a similar study for Flagstaff, Arizona, during the summers of 1961, 1962 and 1963. The results imply that spectacular height increases due to seeding can be expected, but that such cases are relatively infrequent. Specific observations of cloud growth due to seeding are noted, but can only be considered as consistent with these concepts rather than verifying them. The factors important for the seeding effect and the conditions which produce them are also examined. Despite the simplicity of the model, it is felt that the computed height differences qualitatively represent a reasonable measure of the potential for cloud dynamics changes from seeding.
adventures in atmospheric simulation
Authors: Hidy G. M.
Published: August 2018

Laboratory investigations of processes related to atmospheric behavior have long been a resource of fundamental knowledge to workers in meteorology. In fact the history of progress in laboratory simulation closely follows the development of a wide spectrum of key ideas and hypotheses about the atmospheric processes on scales ranging from molecular activity to planetary circulation. This paper presents a very brief survey of the exciting wealth of information evolving from an ever increasing variety of laboratory experiments devoted to atmospheric phenomena.

standardizing meteorological instrument testing1
Authors: Lamb Robert C. , Pharo James A.
Published: August 2018

There presently exists a need for standardized testing techniques for meteorological instrument sensors and systems. It is suggested that representatives of the American Meteorological Society, the National Bureau of Standards, and the meteorological equipment manufacturers meet to determine these standard tests.

It is further proposed that meteorological equipment companies who perform the standard tests on their own equipment be awarded an American Meteorological Society Seal of Approval.
the first color picture of the Earth taken from the ATS-3 satellite
Authors: Warnecke Guenter , Sunderlin Wendell S.
Published: August 2018

The third Applications Technology Satellite (ATS-3) of the National Aeronautics and Space Administration (NASA) was launched into a geo-synchronous orbit at 35,800 km altitude over Brazil on 5 November 1967. One of the meteorological experiments onboard is the Multicolor Spin-Scan Cloud Camera. It provides instantaneous high resolution color pictures of the whole disc of the Earth in a 30-min sequence. Three images are obtained by simultaneous scanning through three different color filters (green, red, blue). The three separate signals are transmitted to the ground station where the multicolor picture is produced.

The first picture of 10 November 1967 is shown on the front page of this Bulletin. The superiority over monochrome pictures (black and white) is demonstrated by the strikingly better contrast between clouds and the background (Earth surface).

A large number of interesting meteorological details are shown in the picture and pointed out in this article. A montage of the ATS-3 picture and an ATS-1 photograph taken on the same day over the Pacific Ocean provides a synoptic picture of the cloud distribution over more than two thirds of the globe.

These successful experiments constitute a large step in obtaining a complete survey on short-time changes of global cloudiness as required for the World Weather Watch.

Published: August 2018

Progress in weather modification is assessed with special emphasis on precipitation modification. Although assessment of progress on a current basis is difficult, an attempt is made to accomplish this on both a problem and a component scale. Much work is being conducted which should significantly improve our ability to increase precipitation in specific targets and minimize risks associated with modification activities.
gun-launched meteorological probe and its application to a global meteorological sounding network
Authors: Williamson L. Edwin
Published: August 2018

This paper covers the general requirements and restraints of a global meteorological sounding network, and presents the gun-launched meteorological probe as a system adaptable to such requirements, with demonstrable operational experience already established. The paper deals with the network requirements in three categories; required surface areas (land or water), payload carriers, and associated data collection and handling facilities. It then discusses the role of the gun-launched probe within the outline of these requirements. Certain sensors are also briefly discussed. The role of the gun-launched probe as a concept applicable to global expansion is presented as one of the most promising of available systems.
Cardiopulmonary remodeling in fattened beef cattle: a naturally occurring large animal model of obesity‐associated pulmonary hypertension with left heart disease

Published: August 2018

The obesity epidemic in developed societies has led to increased cardiovascular diseases including pulmonary hypertension associated with left heart disease (PH‐LHD), the largest and fastest‐growing class of PH. Similar to obese humans, PH and heart failure (HF) are increasingly recognized in North American fattened beef cattle. We hypothesized that PH and HF in fattened beef cattle are novel, phenotypically distinct manifestations of bovine PH arising from left ventricular (LV) dysfunction similar to obesity‐related PH‐LHD in humans. We conducted a semi‐quantitative histopathological assessment of cardiopulmonary tissues obtained from fattened beef cattle suffering end‐stage HF compared to asymptomatic cattle of equivalent age undergoing the same fattening regimens. In HF animals we observed significant LV fibrosis, abundant cardiac adipose depots, coronary artery injury, and pulmonary venous remodeling recapitulating human obesity‐related PH‐LHD. Additionally, striking muscularization, medial hypertrophy, adventitial fibrosis, and vasa vasorum hyperplasia in the pulmonary arterial circulation were associated with sequela of pathologic right ventricular (RV) remodeling suggesting combined pulmonary venous and arterial hypertension. The association between obesity, pathologic cardiopulmonary remodeling, and HF in fattened beef cattle appears to recapitulate the complex pathophysiology of obesity‐associated PH‐LHD in humans. This novel, naturally occurring, and large animal model may provide mechanistic and translational insights into human disease.
Sovietizacija ir kinas: lytis, tapatybė, ideologija filme „Marytė“ (1947)
Authors: Davoliūtė Violeta , Kaminskaitė - Jančorienė Lina
Published: August 2018

[only abstract in English; full article and abstract in Lithuanian]

This article analyzes post-war Sovietization through the prism of the first feature film made in Soviet Lithuania – Marytė – directed by Vera Strojeva and released in 1947, revealing the intention, process and outcome of propaganda in the newly occupied society under Stalinism. As the culture of cinema was part of a broader ideological endeavor, the analysis of this film helps to understand developments across the new Soviet western borderlands. This article reconstructs the context of the narrative of the film, its creation, dissemination and evaluation. The central character of the film is a Soviet Lithuanian war hero – a young female partisan captured and shot in the area of her native Zarasai. The authors analyze the construction of this protagonist in the film following the classical Soviet archetype of the young female “war saint”, similar to the Russian Zoya Kosmodemjanskaja. The choice of a female protagonist for the promotion of the “new Soviet subject” in the recently occupied territory is significant and may be interpreted as a deliberate attempt for encouraging a more sympathetic identification with the Soviet interpretation of history – especially in a country where an anti-Soviet partisan struggle was still taking place. The authors also demonstrate how well-established national and cultural metaphors and narratives were used in constructing a new ideology, considering the focus of this movie on the local level, the cinematic difficulties encountered and the critical reviews. The study employs interdisciplinary methodological tools that demonstrate the benefits of the cultural analysis of text and context.
Netobulas totalumas: kelios pastabos apie erdvinius kompozitus ir kino propagandą

[straipsnis ir santrauka lietuvių kalba; santrauka anglų kalba]

Straipsnyje nagrinėjami pokario kino propagandos tekstai – trys filmai, 1947 m. sukurti Lietuvai, Latvijai ir Estijai kaip šių šalių politinės žiūros ir prieinamų subjekto pozicijų „treniravimo“ įrankis. Pagrindinis klausimas – kiek totalūs, rišlūs yra minėti filmai ir ką reiškia jų kuriamo tolydumo pertrūkiai naratyvinio kino ideologijos kontekste? Atsispiriant nuo Michelio Foucault aptariamos diskurso amplitudės, straipsnyje analizuojami erdviniai kompozitai – montažo figūros, konstruojančios naratyvinį tolydumą ardančias erdves. Paprastai jos laikomos kritinio santykio su dominuojančiu diskursu resursu, tačiau sovietinės ideologijos formavimosi laikotarpio (porevoliucinio Rusijoje ir pokario Baltijos šalyse) medžiaga rodo, kad kai kompozitines erdves gamina hegemonijos centras, jos arba brėžia šios utopinį matmenį, arba žymi negrėsmingą besisteigiančios hegemonijos neišbaigtumą.

Atvirkščiai, jų tikrumas tampa dovana tiems, kurie išdrįsta dalyvauti jų bendruomeniniame gyvenime, ypač daug ankstyvo socialinio gyvenimo sunkumų patyrusiems gatvės jaunuoliams.
Eсomorphic structure of the soil macrofauna communities of technosols of the Nikopol Manganese Ore Basin
Authors: Maslikova K. P.
Published: August 2018

This study established features of the animal population of artificial soil-like bodies – technosols in terms of ecomorphic analysis. The survey was conducted at the research station of the Dnipro State Agricultural University in the city Pokrov in 2012–2014. The experimental polygons were laid within four technosol types: pedozems, sod loess-like lithogenic soils on loam, grey-green clay and red-brown clay. The polygon consisted of 15 transects and each transect was composed of seven test sites. The distance between rows in the polygon was 3 m. Each test site was a square with size 3 × 3 m. The manual sorting of the soil-zoological samples was conducted within each site for areas 0.25 × 0.25 m to the depth where animals were found. Samples were taken in late April or early May. In general, for each period of counting for each polygon 105 soil-zoological samples were taken 123 species of invertebrates were found in the soil macrofauna community of the technosols. These communities are a steppe monoceonosis with a tendency to transformations into pseudoomonoceonosis on account of increased share of pratants. The soil macrofauna of sod lithogenic soils on grey-green clay and loam on loes-like clays is most adapted to xerophilous condition. Animal communities in pedozems and sod-lithogenic soils or on red-brown clay have a more mesophilic character. The trophoceonomorphic structure of the soil macrofauna community indicates a significant potential of the fertility of artificial soil. The aeromorphs’ structure reveals a significant ability of technosols to create cracks and pores, which can lead to hyperaeration. The dominant part of the of soil macrofauna community was hypercarbonatophils. Against the background of the steppe character, the soil macrofauna community had a topomorphic structure that is unusual for natural steppe black soil biogeocenoses on loess-like loam. The trophomorph structure was greatly dominated by phytophages, which indicates the prevalence of processes of mineralization of plant residues under the humification process. The phoromorphic spectrum of soil animal communities was dominated by ecological groups which move without the active construction of tunnels.

Uma Constituição cidadã? Sucessos e limites da institucionalização de um sistema de participação cidadã no Brasil democrático
Authors: Montambeault Françoise
Published: August 2018

A adoção da Constituição democrática de 1988 foi marcada pela vontade de romper com o período autoritário e de incluir a participação ampla dos cidadãos brasileiros nos processos decisórios locais, estaduais e nacionais. Após 30 anos a linguagem da inclusão dos cidadãos e da Constituição cidadã foi retomada pelos políticos de todos os níveis de governos para marcar a ambição democrática e inclusive de suas ambições particulares. Muitas iniciativas participativas foram desenvolvidas e implementadas no Brasil a todos níveis de governo, inclusive ao nível nacional com o crescimento dos conselhos nacionais de políticas públicas nas últimas duas décadas. Qual foi o legado da Constituição de 1988 para a articulação institucional da participação cidadã no Brasil? Este artigo pretende retomar esta questão, enfatizando os êxitos, mas apontando as limitações das disposições constitucionais pelo aprofundamento da democracia brasileira.

Dupuytren’s disease of the foot is not an uncommon disease that affects the plantar aponeurosis. It is a different clinical entity from Dupuytren’s contracture of hands. It presents clinically with slowly growing painless hard nodules on the medial aspects on the feet. Though the pathophysiological mechanisms remain elusive, hyperproliferation of fibroblasts and excessive synthesis of collagen fibers type III are proposed to be the main pathogenetic processes resulting in nodule development and growing. The most widely accepted theory for disease development is the combination of genetic predisposition and environmental risk factors such as smoking chronic alcohol consumption, diabetes mellitus, and other forms of superficial or dee fibromatosis. This article will discuss the dupuytren’s disease of the foot as regards the epidemiology, the pathophysiology, the clinical presentation, diagnosis, and lines of treatment. It will provide a special focus on the mechanisms of affection of plantar aponeurosis.

Das mediações aos Mundos possíveis: percurso teórico metodológico de um estudo de recepção com mulheres encarceradas
Authors: John Valquiria Michela
Published: August 2018

Este artigo apresenta o itinerário teórico metodológico de uma pesquisa que articula a proposição das mediações de Jesus Martin-Barbero e como esta possibilitou compreender  o cotidiano de mulheres em situação de confinamento e como este se (re)configura a partir da mediação da telenovela nesse novo ambiente de socialização. O mapa das mediações de Martin-Barbero não foi o fio condutor do estudo, que se norteia pela persectiva dos mundos possíveis de Galindo Cáceres, entretanto, é justamente no encontro dessas duas perspectivas teórico metodológicas que se buscou compreender como a telenovela medeia o cotidiano de mulheres detentas. Neste contexto, evidencia-se a interrelação das mediações da socialidade, institucionalidade e ritualidade e, acima de tudo, a necessidade de voltar ao primeiro mapa do autor e encontrar numa espécie de nova “cotidianidade familiar” o caminho para compreender os usos e sentidos atribuídos à telenovela por essas mulheres durante o cumprimento de sua pena. O texto busca compartilhar o caminho teórico percorrido, que embora não tenha no mapa das mediações de Martin-Barbero seu modelo metodológico, tem na proposição das mediações o elemento central para compreender a telenovela na prisão como uma instância eminente dos mundos possíveis.

Na realidade, meu contato com essa história começa vinte antes, quando aprendi a conhecê-la no início dos anos oitenta, no Departamento de Português da Pontifícia Universidade Católica de São Paulo (PUC/SP). Foi uma agradável descoberta para mim encontrar ali uma interlocutora com os mesmos interesses e que se tornaria uma grande amiga. Surpreendente naquele momento foi conhecer alguém que dominava com perfeição o idioma alemão, o que lhe dava a imensa vantagem de trazer para o nosso meio lingüístico idéias de autores desconhecidos por brasileiros. Lia e citava já naquele tempo os trabalhos de Roland Harweg, Elizabeth Gülich, Harald Weinrich, Paul Hartmann e muitos outros ignorados por aqui. Desde então não paramos de interagir, seja em intensa correspondência pessoal, projetos de pesquisa conjuntos, mesas-redondas em congressos, bancas examinadoras, cursos em parceria e trabalhos produzidos em co-autoria. Isto me deu o privilégio de conhecer mais de perto esta notável figura humana em todos os sentidos. E é sobre este belo ser humano que vou falar aqui.
Português de moçambique ou as metáforas “à solta”
Authors: Vilela Mário
Published: August 2018

In Mozambique, the Portuguese language, associated with the promotion of national unity and consciousness, has become not only a political-administrative vehicle but also formative of communicative models and a bolster for socio-economic values. By force of the internal structure of the Bantu languages and African imagination, the Portuguese language is dragged toward new, innovative creations, where two aspects can be highlighted: the decomposition of segments of the Portuguese language imitating the Bantu phonetic-discursive sequentialization and metaphoric creation. It is this latter aspect we will be focusing on. The metaphor, provoking breaks in discursive sequence, brings cognitive contributions that are disturbing to our encyclopaedic knowledge. The metaphor, contrarily to metonymy and synecdoche, the metaphor creates categorical conflicts from which new perspectivizations result. The metaphor’s neuralgic crux is to establish negotiations between encyclopaedias. And the “encyclopaedias” focused on (“starting point” or “frame” (Pt. “quadro”) encyclopaedias) are those which result from daily life, from daily concerns, as are “corruption”, the “police” and the “politicians”, economic difficulties, the pleasures of life and the great moral principles of social life. The metaphor found in Mozambican Portuguese generally obeys the parameters of the metaphor: the concrete serves as a basis for abstract things, the physically perceptible is  transferred mentally and contemplates all verbal categories: names and verbs, adjectives and phraseologies, idiomatic expressions and proverbs. The semic and classematic aspects are object of unexpected transferences. It is a new ontology in constant gestation.
Continuidades de tipos de verbos e situações e de formas e categorias verbais e tipos de texto
Authors: Travaglia Luiz Carlos
Published: August 2018

In this paper are presented some results of a research about continuities of types of verbs and situations they express and continuities of verbal forms and categories. These continuities represent resources of sequential cohesion by recurrence, in texts of different types, and the research shows that such continuities function as characterizing elements of text types and also have other functions (relevance, focalization, expression of reality/non reality etc.) in the textual-discursive constitution of linguistic sequences, independently of the text type.

A HOSPITALIDADE NO CINEMA: DISCUTINDO A TEMÁTICA EM TRÊS FILMES LATINO-AMERICANOS
Authors: MAIA Maria de Fátima Queiroz Costa , GOMES Christianne Luce
Published: August 2018

Este artigo objetiva discutir como a hospitalidade é retratada em três filmes: “Que horas ela volta?”, “Nise: o coração da loucura” e “O clube”. A metodologia consistiu em revisão bibliográfica e análise dos filmes para atender a uma abordagem qualitativa do tema. Os estudos e as análises fílmicas evidenciaram que a hospitalidade é exercida no âmbito doméstico, em hospital psiquiátrico, casa de reclusão e em todo lugar onde há a relação hóspede/anfitrião, seguindo funções próprias de receber, hospedar, entreter e alimentar. Os comportamentos de hóspedes e anfitriões, nos filmes, não seguem um conjunto de leis preestabelecidas para a hospitalidade mas quando alguma regra subjetiva é quebrada, pode levar ao seu oposto, que é a hostilidade, como foi verificado nos três filmes.

AbstractThe current–voltage characteristics of p -Si– n -(Si_2)_1 –_ x (ZnSe)_ x (0 ≤ x ≤ 0.01) heterostructures are studied at various temperatures. It is found that the current–voltage characteristics of such structures contain a portion of a sublinear increase in the current with voltage such as V = V _0 exp( Jad ). The concentrations of deep impurities responsible for the appearance of the sublinear portion in the current–voltage characteristic are estimated. The experimental results are explained based on the theory of the injection depletion effect.

AbstractThe properties of porous GaAs samples produced by the electrochemical etching of single-crystal n -GaAs(100) wafers are studied by X-ray diffraction analysis, electron microscopy, and infrared and ultraviolet spectroscopy. It is possible to show that, by choosing the composition of the electrolyte and the conditions of etching, samples can be produced not only with different degrees of porosity and pore sizes (nanopores/micropores), but with another type of sample surface as well. The etching of n -GaAs(100) wafers under the conditions chosen in the study does not change the orientation of the porous layer with respect to the orientation of the single-crystal GaAs(100) substrate. At the same time, etching induces a decrease in the half-width of the diffraction peak compared to that for the initial wafer, a splitting of the phonon mode in the infrared spectra and a partial shift of the components in accordance with the parameters of anodic etching, and a change in the optical properties in the ultraviolet region.

AbstractThe atomic structure of iron–aluminum alloy samples containing about 7 at % of aluminum (α region of the phase diagram) was investigated by X-ray diffraction. The samples were annealed in the paramagnetic ( T > ^T_ C ) and ferromagnetic ( T < T _ C ) states. In the first case, the structural state was fixed by quenching from the annealing temperature in water, and, in the second case, by slow cooling. Diffraction patterns of single-crystal samples were taken on an X-ray four-circle diffractometer. It is shown that local ordering, regardless of the prehistory of a sample, is a combination of B 2-phase clusters (the CsCl type structure), which were previously found in iron–silicon alloys with Si content up to 10%, and small regions with D 0_3 short-range order. The former consist of two B 2-cells having a common face, while the latter consist predominantly of one unit cell of the D 0_3-phase. Within the accuracy of the experiment, no significant difference in the structural states in the paramagnetic and ferromagnetic phases was observed.

AbstractTaking into account the inexhaustible interest in studying the peculiarities of physical properties in the neighborhood of phase transitions and the growth of experimental investigations of cobalt fluoride, we have studied the peculiarities of magnetic susceptibility in the vicinity of the critical field H _C at which cobalt fluoride performs the second-order phase transition from the antiferromagnetic phase to the angular phase. It is discovered that in the magnetic field H ‖ C _4, the magnetic susceptibility becomes infinite at H → H _C. It is shown that as the magnetic field direction deviates from the C _4 axis, the magnetic susceptibility in the critical field H _C proves to be finite. It is also shown that the change in the magnetic susceptibility with the change in the magnetic field considerably decreases at extremely insignificant deviations of the field H from the C _4 axis. Since the calculations are performed in terms of the Landau theory of phase transitions, we pay attention to the similarity and difference between the obtained results and those in the vicinity of the Curie point obtained by using the Landau theory of phase transitions.

AbstractFerroelectric domain structures formed by an electron beam in lithium niobate crystals are studied using low-voltage SEM microscopy. The structures are formed in crystals with different conductivity, including samples with high-resistance congruent composition (CLN) and samples with conductivity increased by reductive annealing (RLN). The potential nature of the contrast of the domain structures observed in the secondary electron mode depending on the conductivity of the samples and the direction of spontaneous polarization of the domains is analyzed. It is assumed that the domain contrast in CLN crystals is associated with long-lived charges localized near domain walls and in the irradiated areas. The recorded domain structures in the CLN crystals are visualized on polar and nonpolar cuts. In the RLN crystals with improved conductivity compared to CLN, the potential contrast of the periodic domain structures is found only on the polar cuts, where vector P _ s of the domains is perpendicular to the irradiated surface. This contrast is likely because the field of the spontaneous electric polarization charges influences the secondary electrons.

AbstractWe have examined temperature changes of the light refraction, birefringence, dielectric permittivity, and dielectric hysteresis loops in Sr_1 – x Ca_ x TiO_3 single crystals with x = 0.014 (SCT-1.4). The dielectric properties of Sr_1 – x Ca_ x TiO_3 with x = 0.007 (SCT-0.7) have been studied. We have performed ab initio calculations of equilibrium structures and total energies for three low-temperature phases of SrTiO_3 and CaTiO_3, based on which we have determined an expected symmetry of the ground state of their solid solution and spontaneous polarization directions in a calcium-induced ferroelectric phase in Sr_1 – x Ca_ x TiO_3. In SCT-1.4, we have separated a spontaneous contribution to the light refraction, which arises due to the spontaneous electrooptical effect caused by the spontaneous polarization and its fluctuations. From the spontaneous contribution to the light refraction, based on a previously developed our phenological approach, we have quantitatively determined for the first time the values and temperature dependences of root-mean-square fluctuations of the order parameter—the polarization P _sh = 〈 P _fl ^2 〉^1/2(short-range, local polar order) in the ferroelectric phase. From optical and dielectric measurements in SCT-1.4, the average value of spontaneous polarization P _ s (the contribution from the long-range order) has been determined. We have estimated the values of P _sh and P _ s , which characterize the short- and long-range orders in the ferroelectric phase of SCT-0.7. Separate determination of the values and temperature dependences of P _ s and P _sh (which considerably exceeds the value of P _ s in the ordered phase) has allowed us to reveal on a quantitative level new particular features of the formation of the induced polar phase in Sr_1 – x Ca_ x TiO_3.

AbstractThe results of experimental studies on estimating the lift force and lift coefficient of a rotating cylinder of constant cross section are presented. The data on the effect of the flow rake angle on the aerodynamic characteristics of rotating cylinders within a range of angles from 0° to 90° are analyzed. It has been established that a decrease in the lift coefficient is observed at flow rake angles above 30°, so the wind engine element shows a positive result within a range of rake angles from–30 ° ≤ α ≤ 30°. The data of these experimental studies can be used for the development of wind engines with blades designed as rotating cylinders with a smooth surface.

AbstractWe present experimental data on the erosion of electrodes made of copper-based pseudoalloys during contact breaking at current amplitudes up to 150 kA in nitrogen at a pressure of ~2 MPa with transverse gas blowing. The electric-erosion characteristics of copper–iron pseudoalloy CuFe (85/15%) electrodes obtained by laser layer melting, as well as CuFe (70/30%) and CuW (25/75%) pseudoalloy electrodes fabricated by traditional powder technology (sintering of pressed powder compacts) are reported. The specific erosion of electrodes in variable-length arc amounts to ~1 mg/C, which somewhat exceeds the value observed for a fixed-length arc discharge gap.

AbstractWe report on room-temperature generation at the 4.8-μm wavelength in a lattice-matched structure of a quantum cascade laser (QCL) grown on indium phosphide (InP) substrate. Laser heterostructures grown by molecular beam epitaxy (MBE) comprised 30 cascades and were designed to generate at the 4.80 μm wavelength corresponding to an atmospheric transparency window. Experiments demonstrated effective lasing at temperatures from 80 to 300 K on a wavelength coinciding with the calculated value, which confirmed the high quality of interfaces, high precision of layer thicknesses, and high accuracy of active region doping.
