Opis:
Single people are often asked about the reasons for non-marriage, in a context where, despite several changes in the field of intimacy, adults are still expected to marry. Based on a thesis study on the subject of singleness in Brazil, in the city of Salvador, Bahia, this text presents the main reasons for singleness, declared by single middle-class adults who live alone in this city. The study used a feminist perspective, with the category gender as the basis for data analysis, in an intersectional way with social class, race, generation, sexuality and territoriality. It used mixed methods with a combination of instruments: questionnaire, focus groups, biographical interviews, and field observations. The findings collaborate to observe gender differences and closeness in reasons for singleness: relational reasons prevailing for women and being single as a choice for men.
Pomimo przemian w sferze życia małżeńsko-rodzinnego oraz intymnych relacji osoby samotne nadal często pytane są o powody pozostawania w stanie wolnym. Od dorosłej osoby wciąż oczekuje się, że wyjdzie za mąż/ożeni się. Niniejszy tekst przedstawia rezultaty brazylijskich badań poświęconych problematyce „singielstwa”. Autorki pracy skupiają się zwłaszcza na głównych powodach pozostawania w stanie wolnym przez osoby dorosłe z klasy średniej, zamieszkujące stan Bahia, miasto Salvador. Do analizy omawianego w tekście zjawiska zastosowano perspektywę feministyczną oraz kategorię gender. Zastosowano podejście intersekcjonalne, biorąc pod uwagę zarówno klasę społeczną, rasę, pokolenie, seksualność, jak i miejsce zamieszkania respondentów- -singli. Zastosowano metody mieszane z wykorzystaniem takich technik badawczych jak: kwestionariusz ankiety, zogniskowane wywiady grupowe (FGI), wywiady biograficzne oraz obserwacje terenowe. Wyniki badań pozwoliły na zaobserwowanie różnic i podobieństw w kwestii przyczyn pozostawania singlem między kategoriami płci. W przypadku kobiet główną przyczyną pozostawania w stanie wolnym są problemy w relacjach z innymi (partnerami), natomiast główną przyczyną bycia singlem w przypadku mężczyzn jest dobrowolny wybór takiego stanu.

Opis:
The triggering of a “dirty bomb” generates a complex scenario, with enormous challenges for the responders due to initial misinformation and the urgency to act quickly yet effectively. Normally, the first 100 h are decisive for perceiving the risk in a more realistic dimension, but the support of methodologies that rely on computational simulations can be valuable when making key decisions. This work seeks to provide support for the early decision-making process by using a Gaussian model for the distribution of a quantity of Cs-137 spread by a radiological dispersive device (RDD). By sequentially joining two independent programs, HotSpot Health Physics codes and RESidual RADiation (RESRAD)-RDD family of codes, we came up with results that suggest a segmented approach to the potentially affected population. These results advocate that (a) the atmospheric stability conditions represented by the Pasquill–Gifford classes and (b) the population subgroups defi ned by radiation exposure conditions strongly influence the postdetonation radiological effects. These variables should be taken into account in the elaboration of flexible strategies that include many climatic conditions and to prioritize attention to different groups of public at risk. During the initial phases of such an event, it is believed that simulations using Gaussian models may be of value in anticipating the possible changes in key variables during the decision-making process. These variables may severely affect the effectiveness of the actions of responders and the general public’s safety.

Opis:
The present paper addresses the modelling of fuel injection at conditions of high pressure and temperature which occur in a variety of internal combustion engines such as liquid fuel rocket engines, gas turbines, and modern diesel engines. For this investigation a cryogenic nitrogen jet ranging from transcritical to supercritical conditions injected into a chamber at supercritical conditions was modelled. Previously a variable density approach, originally conceived for gaseous turbulent isothermal jets, imploying the Favre averaged Navier-Stokes equations together with a “k-ε” turbulence model, and using Amagats law for the determination of density was applied. This approach allows a good agreement with experiments mainly at supercritical injection conditions. However, some departure from experimental data was found at transcritical injection conditions. The present approach adds real fluid thermodynamics to the previous approach, and the effects of heat transfer. The results still show some disagreement at supercritical conditions mainly in the determination of the potential core length but significantly improve the prediction of the jet spreading angle at transcritical injection conditions.

Opis:
O Brasil está inserido em uma dinâmica migratória enquanto origem, passagem e destino de mo-vimentos migratórios. Nesse contexto, o aumento dos números de entrada em comparação com a segunda metade do século XX, a diversidade de origem desses migrantes, o fechamento de fron-teiras de antigos hostlands e a facilidade de entrar no país, aliado com a notoriedade que adqui-riu no Sistema Internacional nos últimos anos, fez com que o país se deparasse com uma nova realidade. O governo Rousseff deparou-se com um cenário no qual surgem os primeiros reflexos da entrada de haitianos, além de outros grupos, como os sírios e venezuelanos, além de localida-des asiáticas e africanas, as quais também tiveram um aumento na entrada de seus nacionais no Brasil. Essa situação teve continuidade durante a gestão de Temer e evidenciou a inadequação da política migratória brasileira, impondo aos governos a tomada de medidas no sentido de pro-curar estabelecer um viés de atuação pautado nos direitos humanos e nos ditames constitucio-nais. A metodologia utilizada recorre à literatura acadêmica pré-existente junto à coleta e análise de documentos oficiais, além de reportagens de veículos midiáticos que versem sobre o tema nos âmbitos nacional e internacional.
Brazil is inserted in a migratory dynamic of origin, passage and destination of migratory movements. In this context, the increase of entry numbers compared to the second half of the twentieth century, the diversity of origin of these migrants, the closing of borders of former host countries and the ease of entering the country, combined with the notoriety acquired on the in-ternational stage in recent years, has forced the country to face a new reality. The Rousseff gov-ernment faced emerging reactions to the entry of Haitians, as well as other groups that had en-tered Brazil in larger numbers, such as the Syrians and Venezuelans, as well as Asians and Afri-cans. This situation continued during Temer’s administration and it evidenced the inadequacy of Brazilian migration policy; it forced governments to take measures to try to establish a plan of action based on human rights and constitutional dictates. The methodological approach was to consult pre-existing academic literature, as well as collect and analyze official documents and media reports on the subject, both national and international.

Opis:
Ultrastructural analyses of fish-infecting myxosporean Henneguya piaractus that is found in the gill lamellae of the freshwater teleost Piaractus mesopotamicus (Characidae) and collected from the Paraguai River, Brazil were described. The parasite occurs within large whitish spherical to ellipsoidal polysporic cysts (up to 2.5 mm long) delimited by a layer of fibroblasts generally connected with some capillaries on the gill epithelium. No external morphological signs of disease were visible in the infected fishes. The tailed spores measured 61.5 ± 0.91 (60.2–62.6) μm in total length and ellipsoidal spore body 21.1 ± 0.62 (20.6–21.9) μm long, 6.7 ± 0.40 (6.2–7.3) μm wide and 2.5 ± 0.54 (2.0–3.1) μm thick. The spore wall was about 97 nm of thickness and consisted of a thin electron-dense exospore and a thick electron-lucent endospore with about 85 nm of thickness. The tailed spores were composed of two equal–sized shell valves adhering together along the straight suture line each having in continuity a equal caudal tapering tail measuring 40.5 ± 1.02 (38.7–43.1) μm in length. Two symmetric polar capsules measured 9.8 ± 0.28 (9.3–10.1) μm long and 1.9 ± 0.37 (1.4–2.4) μm wide, each having a polar filament with 10–11 (rarely 12) coils

Opis:
Control failure of pests and selectivity of insecticides to beneficial arthropods are key data for the implementation of Integrated Pest Management (IPM) programs. Therefore, the aim of this study was to assess the control failure likelihood of Plutella xylostella and the physiological selectivity active ingredients to parasitoid Oomyzus sokolowskii (Hymenoptera: Eulophidae) and to predators Polybia scutellaris (Hymenoptera: Vespidae) and Lasiochilus sp. (Hemiptera: Anthocoridae). In bioassays, P. xylostella larvae and O. sokolowskii, P. scutellaris and Lasiochilus sp. adults were used. Concentration-mortality curves of six insecticides for P. xylostella were established. These curves were used to estimate the mortality of P. xylostella at the recommended concentration, in order to check a control failure of insecticides to this pest. Furthermore, the lethal concentration for 90% of populations (LC90) and the half of LC90 were used in bioassays with the natural enemies to determine the selectivity of these insects to insecticides. All tested insecticides showed control failure to P. xylostella, indicated by high LC90 and low estimated mortalities (less than 80%). The cartap insecticide was selective in half of LC90 to Lasiochilus sp. and moderately selective in LC90 and the half of LC90, to Lasiochilus sp. and P. scutellaris, respectively. Deltamethrin was moderately selective in the half of LC90 to predator Lasiochilus sp. Cartap, carbaryl, and deltamethrin reduced the mortality of Lasiochilus sp. in the half LC90. The results also showed that the insecticides methamidophos, carbaryl, parathion methyl and permethrin were not selective to any of the tested natural enemies. The role of insecticides in IPM systems of Brassica crops is discussed based on their control failures to P. xylostella and selectivity to their natural enemies.

Opis:
In this paper we present a MOSFET-only implementation of a balun LNA. This LNA is based on the combination of a common-gate and a common-source stage with cancellation of the noise of the common-gate stage. In this circuit, we replace resistors by transistors, to reduce area and cost, and to minimize the effect of process and supply variations and mismatches. In addition, we obtain a higher gain for the same voltage drop. Thus, the LNA gain is optimized and the noise figure (NF) is reduced. We derive equations for the gain, input matching and NF. The performance of this new topology is compared with that of a conventional LNA with resistors. Simulation results with a 130 nm CMOS technology show that we obtain a balun LNA with a peak gain of 20.2 dB (about 2 dB improvement), and a spot NF lower than 2.4 dB. The total power consumption is only 4.8 mW for a bandwidth higher than 6 GHz.

Opis:
Eragrostis tenuifolia is a weed species that is gaining ground in Brazil. This weed occurs in pastures, grasslands, crop fields, and roadsides. The objective of this study was to examine the effects of different environmental factors on E. tenuifolia seed germination and seedling emergence. The optimum constant temperature for germination was around 35–30°C. It was also found that 85% of seeds germinated under a 30/20°C alternate temperature regime. Light appears to have a positive effect on seed germination. No seedlings emerged when seeds were buried 3 cm or deeper. The results suggested that E. tenuifolia has the potential to spread into pastures and in no-tillage crop systems in Brazil. Measures such as the use of cover crops and/or soil cultivation can be used to limit germination and seedling emergence, respectively.

Subject and purpose of work: The purpose of this article is to present the vision of ECLAC - Economic Commission for Latin America and the Caribbean and its contribution to the reflections on economic development. Materials and methods: This is an exploratory and descriptive study. The first part of the paper contemplates the emergence and evolution of ECLAC thinking during its more than sixty-five years of existence. The second deals with dependency theory, ending with the current thinking proposed by ECLAC. Results: It results in a brief analysis of the moment of the globalization of the economy as an exclusionary process in the history of capitalism, emphasizing the importance of the ECLAC thinking, reinvigorated nowadays. Conclusions: It is considered that the dependency theory has been the great contribution of ECLAC thinking, with the change of focus from a viewpoint only from the prism of the central countries, to an optic from the point of view of the peripheral countries.
Przedmiot i cel pracy: Celem tego artykułu jest przedstawienie wizji ECLAC - Komisji Gospodarczej Narodów Zjednoczonych ds.

Detergents at waters inducing negative changes for biological degradability and water general quality. Some authors have evidenced a considerable amount of anionic surfactant and toxic effects into natural water and effluents related to detergents. The objective of the study was to apply electron irradiation for reducing toxicity, and for degradation of surfactants. To quantify surfactant LAS determination as MBAS (metylene blue active substances) was applied. The capacity of radiation to reduce surfactants was evidenced for real effluent and for water solution containing sodium dodecyl sulfate, linear alkylbenzene sulfonate (LAS), separately. An electron beam accelerator (EBA) 1.5 MeV was the radiation source. Anionic surfactant solutions as well as real effluents resulted in less toxic samples after irradiation. Toxicity was evaluated for Vibrio fischeri and Daphnia similis. An important decline of total anionic surfactant was observed after irradiation to doses: 6.0 kGy and 20 kGy (surfactant in water solutions and effluents, respectively). To conclude, EBA irradiations accounted for 88% to 96% less toxic surfactants solutions and effluents and 68% to 96% for MBAS compounds decomposition.

Opis:
The viability of partial replacement of biomass feedstock by the refuse derived fuel (RDF) produced from the local municipal waste management facility was investigated. Therefore, over two years, several samples of the rejected fractions from the selective collection operations and the mechanical and biological treatment were collected at the waste management facility. These samples were characterized to evaluate the physical composition, proximate analysis, ultimate analysis, alkali metal and trace metal content, calorific, and chlorine contents. All data were statistically analyzed. Several important differences were found between the rejected fractions and biomass, namely moisture, volatile matter, and fixed carbon content. However, the calorific value is like the expected from common wood or forest wastes. Trace and hazardous elements were found to be below the standard for RDF. After the statistical analysis, it was found that not all parameters had a normal distribution. Non-parametric tests were performed and for all the parameters analyzed only moisture content, nitrogen, and hydrogen show to be dependent on the waste source. Overall, the results point out the feasibility to prepare RDF from rejected fractions to use as co-fuel in a biomass power plant.

The paper discusses the intrinsic potential offered by classroom interaction for language development. The first part examines several theoretical aspects and characteristics of classroom communication. The second part presents the results of a study which investigates different aspects of classroom interaction in foreign language teaching and the strategies used to encourage classroom communication in the target language. The study, which combines quantitative and qualitative research methods, is based on a survey of Slovene teachers teaching English in primary school. Results suggest that while the respondents are well aware of the benefits of using English in classroom communication, they generally use it in an arbitrary and unsystematic fashion. We would like to argue that we can contribute to the effectiveness of the teaching process by approaching classroom communication with a systematic and consistent format.

The main aim of this paper is to present the situation of Gamilaraay, an Aboriginal language spoken in New South Wales, Australia, currently undergoing a revitalization (Giacon 2007) . After discussing the classification of the world’s languages according to their vitality, the author presents the language situation in Australia and offers a definition of revival linguistics (see Zuckermann & Walsh 2011), a new branch of linguistics as yet little known in Poland, justifying its relevance to the revitalization of Aboriginal languages. Special attention is given to the language situation in New South Wales, and to the specific revivalistic attempts undertaken by linguists there (Troy & Walsh 2010). Some morphological, syntactical and lexical features of Gamilaraay are described in order to show the complexities of language revival and problems revivalists have to face.
