Authors: Makunde Privilege , Slippers Bernard , Bush Samantha , Hurley Brett
Published: February 2023

Spondyliaspis cf. plicatuloides (Froggatt) (Hemiptera: Aphalaridae) is native to Australia but was first detected outside its native range in 2014, in South Africa. It feeds on eucalypt species and thus has the potential to become a pest in commercial Eucalyptus plantations. Information on the basic biology of this insect, which is important for the development of surveillance and management strategies, is lacking. To investigate the life cycle and general biology of S. plicatuloides, the psyllid was reared under controlled glasshouse conditions on potted red-flowering gum, Corymbia ficifolia. The egg incubation period, number of nymphal instars and their developmental time, adult fecundity, adult longevity and duration of the life cycle were determined. The major diagnostic features used to differentiate the five nymphal instars were the number of antennal segments, wing pad development and body length. Females reached reproductive maturity 2.3 ± 0.47 (mean ± SD) days after eclosion and laid 16.2 ± 3.9 (mean ± SD) eggs on average. Reproduction was sexual. The first nymphal instar took 10.7 ± 1.2 (mean ± SD) days to hatch from the egg. The nymphal instars completed their development in 22.6 ± 1.4 (mean ± SD) days under the brown scalloped shelters they secrete. The insect's total life cycle lasted 37.37 ± 1.17 (mean ± SD) days from egg to adult death. Males and females lifespan is also reported. The study provides the first information on the basic biology of S. cf. plicatuloides that will be useful for future studies on surveillance and management strategies.

The regularities of the generation of gas-discharge beam-plasma formations formed in a high-current non-self-sustained glow discharge at low (≈ 1 Pa) pressure in an extended, 1.2 m long, hollow cathode with a volume of 0.34 m3 with a length-to-diameter ratio of 2: 1 were investigated. It is shown that in a system with one electron source providing injection of electrons into the hollow cathode of a glow discharge, a sharp nonuniformity (≈ 40%) of the nitrogen plasma concentration distribution is observed. In an extended hollow cathode, the problem of inhomogeneity of the plasma concentration distribution is solved by using two sources of electrons that provides injection of electrons from the auxiliary arc plasma into the hollow cathode of the glow discharge. The use of two sources of electrons makes it possible to form beam-plasma formations with an inhomogeneity of no more than 18%. A source of beam-plasma formations based on a non-self-sustained glow discharge with an extended hollow cathode was used for ion-plasma treatment of Cr12MoV die steel products.

The article presents preliminary results for the potential energy calculations of the interacting O3-O2 complex. The study of this complex is important for modeling the reaction of the ozone formation in the stratospheric layer of the Earth's atmosphere. The calculations were carried out from the first principles ( ab initio ) of the quantum theory using the explicitly correlated spin-unrestricted coupled clusters method [UCCSD(T)-F12a] in a combination with the correlation-consistent basis set [aug-cc-pVTZ] to describe the molecular orbitals. The obtained radial dependences at the selected angular orientations are discussed in comparison with the O3-N2 complex.

Using the methods of transmission electron diffraction microscopy the structure phase state and defect substructure in head of differentially quenched 100-meter rails at different depth after ultra long-term operation (passed gross tonnage 1770 mln. tons) are studied. The investigations are carried out along the rail head central axis of symmetry and working fillet rounding radius at the distances 0, 2, 10 mm from the tread surface. Dislocation ferrite substructure is presented by chaotically distributed dislocations and nets. The scalar and excess dislocation density increase as they approach the head rail surface. The values of these parameters on the surface are more than twice the corresponding value at a depth of 10 mm. The value of excess dislocation density is lower than scalar dislocation density which indicates elastic character of crystal lattice curvature-torsion. The quantitative evaluation of mechanisms dislocation strengthening is carried out.

The paper studies the evolution of the structure, phase composition, and impact toughness of the Ti-6Al-3Mo titanium alloy after two types of processing, one of them is included heating and hot helical rolling with quenching in water (mode I). The additional air quenching is used between the rolling and quenching processes in mode II. This approach with combining two cooling stages (in air and in water) of the alloy makes possible to control the recrystallization time and form a gradient structure over the cross-section of the bar stock. The processing of titanium alloy according to mode I lead to decrease of impact strength. The addition of air-cooling stage (in mode II) leads to insignificant decrease hardness and increase toughness of alloy. The treatment by mode I and II of the titanium alloy lead to formation of the structure which contain large grains of the primary α-phase in thin-plate structure of the secondary α-phase in the β-phase. It is shown that the obtained structure states of alloy affect to crack propagation under impact loading and changing the amount of energy which spent to the complete destruction of the samples.

It was found that after modification and irradiation, new compounds are not formed, in the IR spectra the intensity of some bands decreases, the reflectivity decreases in the range from 0.4 to 2.2 μm. An absorption band appears in the visible region with a maximum at 420 nm, caused by intrinsic point defects of ZnO; its intensity increases with increasing electron fluence. In the near-IR region, after irradiation, induced absorption appears due to free electrons. Comparison with unmodified ZnO powder showed the effectiveness of modification to increase radiation stability.

Published: February 2023

The results of measurements of the high-temperature internal friction background of the heat-resistant alloy VZh171 in the initial state and after volume nitriding presented. The obtained data used to study the regularities of the transition from the elastic to the viscoelastic state of the material at elevated temperatures. Nitriding the alloy leads to an increase in the transition temperature to the viscoelastic state from 571 K (initial state) to 763 K (after nitriding). The values of activation energy of the high-temperature internal friction background obtained: U f = 0.63 ± 0.01 eV for the alloy VZh171 in the initial state and U f = 0.59 ± 0.01 eV for the alloy after volume nitriding. The activation energies U 0 of the processes responsible for the formation of the viscoelastic properties of the substance are estimated: U 0 ≈ 2.52 eV for the alloy in the initial state, U 0 ≈ 2.36 eV for the nitrided alloy. The obtained values U 0 correspond to the self-diffusion activation energy in nickel, the main component of the alloy matrix. The appearance of dispersed nitride phases in the matrix leads to a decrease in the activation energy of viscoelasticity processes by about 6%. Possible reasons for the change in the transition temperature and the activation energy of the viscoelastic state at moderately high temperatures as a result of nitriding discussed.

The paper presents the results of mechanical tests of promising magnesium alloys for medical use of ternary alloying systems Mg-Zn-Ca and Mg-Zn-Y. The temperature and strain rate sensitivity features of the loading curves are discussed, in particular, the simultaneous significant increase in plasticity and a decrease in the interval of stable plastic flow with increasing temperature. The experimentally obtained value of the activation energy of the dislocation annihilation will make it possible to predict the true plastic deformation corresponding to the point of loss of plastic flow stability at various temperatures. The prospects for the possible use of the obtained results in technological processes for the manufacture and operation of medical devices are discussed.

Published: February 2023

The article analyzes derivational and semantic parallels in Yiddish and Ukrainian from the standpoint of the author’s linguistic hybridity theory. It presents the results of a comparative study of prefixed verbs used in the story “Shiker” by the Soviet Yiddish writer Der Nister and its Ukrainian translation “Spyanilo” (by E. Raitsin). Linguistic parallels are shown as Slavic phenomena in the Yiddish prefixed verb derivation and semantics, resulting from the Slavic adstrate influence on Middle High German – the basis language of Yiddish. The German expression plane of the studied Yiddish prefixes and their genetically Slavic or both German and Slavic content plane are discussed in terms of comparative history. The comparative studies shows that more than half of the verbs in the Yiddish source text contain semantically Slavic homonymous prefixes and German-Slavic hybrid polysemous prefixes. In terms of translatology, it is shown that the absolute majority of these verbs are translatable into Ukrainian by simple morphemic and alternative morphemic substitution. In the general theoretical aspect, the terms and concepts “homonymous prefixes” and “hybrid polysemous prefix” are specified. It has been proved that the Yiddish-Slavic parallels between Yiddish source and Ukrainian target language / between Yiddish original and its Ukrainian translation are an additional evidence of the German-Slavic hybridity of Yiddish as a genealogically Germanic language.

An Analysis on Foregrounding in Miss Brill from the Perspective of Functional Stylistics
Authors: Lang Wenjuan , Liu Meiyan
Published: February 2023

Miss Brill is the masterpiece of modern short story writer Katherine Mansfield, telling the story of an old English lady wandering in France who is hurt by a pair of young lovers. Most of the previous studies on the novel focused on its narrative angle and theatricality. This paper adopts the foregrounding analysis framework of functional stylistics to quantitatively and qualitatively analyze the parallelism and deflection features of foregrounding in Miss Brill at the phonological level, the graphological level, the lexical-grammatical level, and the semantic level. This paper finds that: in Miss Brill, the foregrounding features at the phonological level are the use of alliteration and coda; the foregrounding features at the graphological level are the parallelism of punctuation; the foregrounding features at the lexical-grammatical level are manifested in the widespread use of material and mental processes, the emergence of high-value, median-value, and low-value modalities, and the extensive use of marked themes; the foregrounding features at the semantic level are parallel means of connection. These foregrounding methods can better reflect the ideational function, interpersonal function, and textual function of the text, and at the same time, they can also highlight Miss Brill’s tragic living state and her escapist psychological state to readers. By analyzing the foregrounding features of Miss Brill at various language levels and their stylistic effects, this paper vividly displays the story, helps readers understand the language features of the novel, and enhances their comprehension of the topic of the story. Thereby, the readers’ ability to appreciate such novels can be improved, and a new research perspective is provided for the analysis of foregrounding in novels.

Although recent developments in the field of translation studies have brought theory building to a new level unrestrained to comparative textual analysis by incorporating system cultural theories, the lack of a consistent model for descriptive translation studies is still a problem not to be overlooked. In light of the theories of quality assessment proposed by scholars such as Toury and House, this paper seeks to lay the groundwork for the construction of a systematic model for literary translation review, in specific hope to provide a solution to the chronic issue of exaggerated foreignization in Mandarin translation of English works. It begins by reviewing and evaluating the theories of ‘equivalence’ as well as ‘targetoriented’ and ‘source-oriented’ translation proposed by major theorists over time, and then on such basis, stating its own methodology which combines descriptive and register analysis. This paper then bases its discussion and paradigm building on Alice Walker’s short story, Everyday Use. It proposes, after a thorough case study, a possible solution to the above-mentioned problem: lexical chunk theory. The paper closes by providing an overview of the theoretical initiations embedded in it and pointing to new directions of further investigation.
Beyond Hofstede Dimension Model: A New Cultural Dimension of Context Culture
Authors: Wu Shaofen
Published: February 2023

With significant political and economic changes over the decades, the limitations of Hofstede's cultural difference dimension model have been heated debated. The purpose of this research is to explore the levels of context culture among people in China of different ages and genders and whether context culture should be considered as part of the cultural dimension. The respondents were 385 people aged 20 to 40 in China, and the study was quantitative, using independent sample tests to answer research questions. This research shows that China is a high context culture country, and the women have higher context culture than men. In addition, context culture differs significantly in age groups, and the level of context culture increases with age. Therefore, context culture can be considered as a new cultural dimension, and it is also suggested to add this new dimension to Hofstede's cultural dimensions model to examine culture more comprehensively.

Os conflitos socioambientais em estudo dizem respeito às disputas territoriais e dinâmicas socioambientais nos territórios de comunidades vazanteiras no Norte de Minas, devido à implantação de Unidades de Conservação, como condicionantes ambientais ao Projeto Jaíba. Ou seja, dinâmicas sociais que estruturam esse campo ambiental ocupado por vários atores, tais como: comunidades tradicionais vazanteiras (Pau de Légua, Pau Preto e quilombo da Lapinha), ruralistas e Estado, com perspectivas, identidades e práticas distintas. Objetivo deste trabalho foi analisar os conflitos socioambientais que envolvem a criação das Unidades de Conservação e os direitos territoriais das comunidades tradicionais vazanteiras, quilombolas e pescadoras da região norte do estado de Minas Gerais. A metodologia utilizada para a construção do artigo foi à pesquisa bibliográfica, da qual parte do campo da Ecologia Política, ou seja, que compreende a natureza de forma dialética, enquanto ambiente natural e, ao mesmo tempo, ambiente construído socialmente. Os resultados demonstram que ainda está em curso o conflito ambiental entre as comunidades tradicionais Vazanteiras e as Unidades de Conservação do tipo Unidades de Proteção Integral, sobretudo, Parques Estaduais. Uma vez que essas populações reclamam o seu direito de uso, acesso e ocupação dos seus territórios, apesar de sofrerem com a permanência desses parques que se inserem dentro das estratégias de promoção de áreas de conservação dos recursos naturais como ações de mitigação da degradação ambiental provocada pelos projetos de desenvolvimento agropecuários financiados pelo próprio Estado, neste caso, o Projeto Jaíba.

O objetivo central desse trabalho é discutir como os serviços de saneamento básico são tratados no contexto da Região Metropolitana de Goiânia (RMG). Para atingir os objetivos foram realizados análise bibliográfica e documental, coleta de dados secundários e mapeamento das informações. A distribuição espacial dos serviços nos permitiu compreender as contradições presentes entre a legislação e a oferta do saneamento básico. Por fim, apresenta-se a importância e oportunidade de ações conjuntas para que haja maior integração em ambientes metropolitanos por meio da oferta de serviços e infraestruturas.

Published: February 2023

O presente artigo foi desenvolvido no município de Horizonte-Ceará, que está situado na região metropolitana de Fortaleza, distanciado a 40km da capital cearense. A atividade extrativa de areia uma das formas de desenvolvimento da mineração ocorre há bastante tempo no município, mesmo antes de sua emancipação na década de 80 e tem se desenvolvido de forma significativa devido à crescente urbanização desencadeada nas últimas décadas que exigiu uma maior demanda por matéria-prima para a construção civil. Nesse sentido, este trabalho teve como objetivo central identificar os impactos ambientais oriundos dessa atividade desenvolvida no município. Na sua delimitação territorial foram identificadas vinte extrações de areia, sendo seis ativas e doze inativas. Os impactos ambientais positivos e negativos foram identificados e descrito através da associação das atividades impactantes ao meio ambiente e os aspectos ambientais existentes na área, para isso foi utilizado o método de avaliação de impacto ambiental Matriz de Leopold.

Os incêndios florestais geram problemas em diversas escalas, sendo que em Unidades de Conservação promovem a degradação da vegetação, impactos significativos sobre a biodiversidade, prejuízos financeiros e até mesmo perda de vidas. Neste contexto, o objetivo deste artigo foi analisar e mapear os focos de incêndio no Parque Nacional de Ilha Grande (PNIG), no mês de agosto de 2019, bem como identificar a evolução da área queimada ao longo do período. Para o mapeamento da área queimada diariamente foram utilizadas imagens do satélite AQUA M-T juntamente com os focos de calor adquiridos do Banco de Dados de Queimadas disponível no site do INPE. E, para mostrar a relação da área queimada com as variáveis meteorológicas foram utilizados os dados da estação meteorológica de Itaquiraí – MS. Os resultados mostrar que no período analisados foram queimados 85% do PNIG, com destaque para o dia 14/09 com 336,44km² de área atingida. Foi possível ainda constatar que as variáveis meteorológicas, principalmente a velocidade do vento, possui relação direta com a área queimada, ou seja, quanto maios a velocidade do vento, maior a área atingida.

O Semiárido brasileiro possui características marcantes nos seus aspectos socioambientais, em destaque as questões climáticas e hídricas, além do fenômeno das secas e do processo de desertificação que se materializa na interface da relação entre a sociedade e a natureza. Ainda neste sentido, tem-se o setor das atividades financeiras influenciadas pelo poder das oligarquias locais. No entanto, políticas públicas são exercidas na região, entre tais políticas, cita-se o incentivo à introdução da espécie vegetal, Prosopis juliflora (Sw.)DC., com inserção influenciada pelas suas características como o alto potencial forrageiro e a adaptabilidade de manter-se verde em pleno período seco, o que seria assim, a espécie “salvadora” e com alternativas socioeconômicas ao Semiárido. No entanto, passadas décadas da inserção das algarobeiras surgiram pesquisas acerca do seu comportamento como espécie invasora, com estudos que demonstraram relações da espécie com diminuição da riqueza da fitodiversidade da Caatinga, entre outros impactos, que muitas vezes conduzem à desertificação. Visto a dualidade que a espécie representa, buscou-se analisar as produções científicas acerca das percepções e da sua trajetória, que vai desde o aporte sociopolítico de sua inserção ao seu enquadramento como problemática ambiental. Para isso, aplicou-se a análise de produções científicas regidas em princípios estatísticos que utilizam de indicadores bibliométricos. Assim o estudo veio a demonstrar as tendências e correntes das produções a nível global e regional, retratando todo o histórico de introdução da espécie e dissertando acerca da sua relevância socioeconômica e do seu comportamento como espécie invasora e impactos ambientais.

Authors: Manoj D H  , Mounika DS
Published: February 2023

On January 21 2021, India granted emergency use authorization to Covishield (non-replicating adenovirus vaccine) and Covaxin (viral inactivating vaccination). Reports till 02 Jan 2023 suggest a cumulative total of 2,20,10,77,192 vaccination doses administered among the Indian Population. A sore arm, fever, and myalgia are the most common side effects of covid-19 immunization, according to the UK's Medicines and Healthcare Products Regulatory Agency (MHRA). COVID-19 vaccination has not been shown to negatively affect fertility in any of the clinical trials. However, patients who have encountered alterations in their menstrual cycle and bleeding patterns quickly after vaccination are increasingly approaching primary care providers and reproductive health professionals

Therefore, our study aims in collecting data from pre-menopausal, vaccinated women regarding alterations in their menstrual cycle post COVID-19 Vaccination through a self-administered pre-validated Questionnaire.

Our study implies that almost 77.9% of the study participants did not observe any menstrual changes while 23.1% of the reported abnormal menstruation cycles which included delayed cycles, early cycles, less bleeding than normal and change in blood color.

Our study’s conclusion highlights the need for larger studies to identify the possibility for a relationship to exist between COVID 19 Vaccination and Menstrual cycle.
