Numerical Simulation of Hydrogen Leakage from Fuel Cell Vehicle in an Outdoor Parking Garage
Authors: Shen Yahao , Zheng Tao , Lv Hong , Zhou Wei , Zhang Cunman
Published: August 2021

It is significant to assess the hydrogen safety of fuel cell vehicles (FCVs) in parking garages with a rapidly increased number of FCVs. In the present work, a Flame Acceleration Simulator (FLACS), a computational fluid dynamics (CFD) module using finite element calculation, was utilized to predict the dispersion process of flammable hydrogen clouds, which was performed by hydrogen leakage from a fuel cell vehicle in an outdoor parking garage. The effect of leakage diameter (2 mm, 3 mm, and 4 mm) and parking configurations (vertical and parallel parking) on the formation of flammable clouds with a range of 4–75% by volume was considered. The emission was assumed to be directed downwards from a Thermally Activated Pressure Relief Device (TPRD) of a 70 MPa storage tank. The results show that the 0.7 m parking space stipulated by the current regulations is less than the safety space of fuel cell vehicles. Compared with a vertical parking configuration, it is safer to park FCVs in parallel. It was also shown that release through a large TPRD orifice should be avoided, as the proportion of the larger hydrogen concentration in the whole flammable domain is prone to more accidental severe consequences, such as overpressure.
MEGAREGIONS: CAUSES, SCOPE, CHARACTERISTICS AND CHALLENGES OF DEVELOPMENT
Authors: Ziyatdinov T.
Published: August 2021

Megalopolis is considered as a merger of a number of agglomerations, which have synergistic effect. The megaregion is a more complex system relative to its constituent agglomerations and has the sum of their synergies and new emergent qualities. The domestic and foreign terminology used for the designation of megaregions is given. The existential cause is determined, the economic, social factors and synergistic effects of the functioning of mega-agglomerations are identified. The stages of the structural and planning formation of megalopolises are reflected graphically and in tabular form. The correlation between the capacity building of megalopolises and the development of the transport infrastructure of their territories is noted. The structural and planning characteristics and urban development trends of megalopolises are revealed. The characteristics of the types of planning structure of megalopolises are given. Polycentricity and prevalence of linear-axial development of the architectural and planning structure of megalopolises are shown. The constant territorial and spatial expansion of mega agglomerations is noted. The modern urban planning problems of megalopolises' development are set: the lack of urban regulation of their development, the lack of professional personnel in the field of their planning, the lack of a theory of megalopolises' development, excessive pressure on ecosystems. Extrapolation of the territorial growth of the combined metro areas allows to predict their merger into a single urbanized "network" of the planet. The prerequisites for the development of the latest urban development trend of the XXI century – the formation of crossborder megaregions are highlighted.

Published: August 2021

Artificial resonant metamaterial with subwavelength localized filed is promising for advanced nonlinear photonic applications. In this article, we demonstrate enhanced nonlinear frequency-agile response and hysteresis tunability in a Fano-resonant hybrid metamaterial. A ceramic cuboid is electromagnetically coupled with metal cut-wire structure to excite the high-Q Fano-resonant mode in the dielectric/metal hybrid metamaterial. It is found that the significant nonlinear response of the ceramic cuboid can be employed for realization of tunable metamaterials by exciting its magnetic mode, and the trapped mode with an asymmetric Fano-like resonance is beneficial to achieve notable nonlinear modulation on the scattering spectrum. The nonlinear tunability of both the ceramic structure and the ceramic/metal hybrid metamaterial is promising to extend the operation band of metamaterials, providing possibility in practical applications with enhanced light-matter interactions.
Dynamic Simulation of Space Debris Cloud Capture Using the Tethered Net
Authors: Wang Qingtao , Jin Dongping , Rui Xiaoting
Published: August 2021

Space debris, especially the space debris cloud, has threatened severely the safety of future space missions. In the framework of multibody system dynamics, a computational approach is proposed in this study to investigate the dynamics of net deployment and capture of space debris cloud using this net subject to large overall motions and large deformations. To obtain high simulation fidelity of capturing space debris cloud, the gradient deficient beam element of the absolute nodal coordinate formulation (ANCF) is employed to discretize threads which are woven into the net. The normal contact force between the net and the debris cloud and among debris particles is computed by using the penalty method. Some deployment examples are presented to investigate the influences of shooting velocity of bullets and microgravity as well as the angle between the traveling direction of the net and the microgravity direction on the deployment characteristics of the tethered net. Other capturing examples are given to clarify the effect of the deployment area of the net at the moment it starts to contact with the debris cloud on the capture rate and to demonstrate the effectiveness of the proposed approach for capturing space debris cloud using the net in microgravity conditions.
Rethinking Strategy for Gender Equality in Trade Unions
Authors: Tjandraningsih Indrasari
Published: August 2021

The non-strategic role and position of women workers in trade union organization, even in the women-dominated sector, is hardly changed even though the number of women members of trade unions is increasing. Various programs have been carried out to increase the strategic role of women in trade union organizations but so far have not shown significant results. Based on interviews with officers of gender equality programs for trade unions, union leaders and women and men members and literature studies this paper offers an idea of the need for a non-exclusive approach and actively and proportionally involving men in awareness-raising and gender equality programs for trade unions. This idea is based on the fact that in trade unions gender-related program is always left to or only involves women. The strategy in the gender equality awareness and improvement program that only involves women causes the program’s effectiveness to be low because half of the causes of the problem is not involved.

Literaturas africanas, história e cultura: uma arqueologia radical e diversas interrogações
Authors: Martinho Ana Maria
Published: August 2021

Neste artigo procuramos discutir algumas das questões que a circulação do texto literário africano impõe e permite, na contemporaneidade, sendo certo para nós que tal só pode ser concretizado quando posto em relação com a história, a cultura, as artes. O futuro da receção e estudo destas literaturas depende da mudança assumida dos lugares de escuta, de fala e de produção crítica e aí pode residir a sua importância na desconstrução de modelos convencionais de leitura, o que entendemos como fundamental. Por isso nos interessam o escopo da definição de literatura radical e correspondentes metodologias críticas subversivas. A literatura, tal como as artes e a história, pode responder no fundo a questões da natureza equivalente, nomeadamente àquelas que rompem com o cânone e que não se limitam à discussão do que mudou entre textualidades de validação colonial e as suas muitas versões pós-coloniais.

Inversión extranjera directa y productividad laboral en la industria manufacturera regional
Authors: Rangel González Erick , López Ornelas Luis Fernando
Published: August 2021

La Inversión Extranjera Directa (IED) es a menudo señalada como un factor impulsor del crecimiento económico, si bien no existe un consenso en la evidencia empírica a nivel internacional respecto a su efecto sobre la productividad laboral. El presente documento analiza los efectos de la Inversión Extranjera Directa sobre la productividad laboral en el sector manufacturero en México durante el periodo 2007-2015 utilizando datos panel y empleando como unidad de análisis a las entidades federativas del país. Las estimaciones se realizan empleando el método generalizado de momentos, el cual permite considerar posibles problemas de endogeneidad. Los resultados indican un efecto positivo y estadísticamente significativo de la IED como proporción del PIB manufacturero sobre la tasa de crecimiento de la productividad laboral estimada a partir del Índice de Productividad Laboral de las Manufacturas publicado por INEGI. Resultados similares se encuentran si el crecimiento en la productividad laboral se estima por medio del PIB manufacturero por trabajador, si bien estos últimos cuentan con menor poder estadístico en algunas especificaciones.
A Method for Electrical Property Tomography Based on a Three-Dimensional Integral Representation of the Electric Field
Authors: Eda Naohiro , Fushimi, Motofumi , Hasegawa Keisuke , Nara Takaaki
Published: August 2021

Magnetic resonance electrical properties tomography (MREPT) noninvasively reconstructs high-resolution electrical property (EP) maps using MRI scanners and is useful for diagnosing cancerous tissues. However, conventional MREPT methods have limitations: sensitivity to noise in the numerical Laplacian operation, difficulty in reconstructing three-dimensional (3D) EPs and no guarantee of convergence in the iterative process. We propose a novel, iterative 3D reconstruction MREPT method without a numerical Laplacian operation. We derive an integral representation of the electric field using its Helmholtz decomposition with Maxwell’s equations, under the assumption that the EPs are known on the boundary of the region of interest with the approximation that the unmeasurable magnetic field components are zero. Then, we solve the simultaneous equations composed of the integral representation and Ampere’s law using a convex projection algorithm whose convergence is theoretically guaranteed. The efficacy of the proposed method was validated through numerical simulations and a phantom experiment. The results showed that this method is effective in reconstructing 3D EPs and is robust to noise. It was also shown that our proposed method with the unmeasurable component H− enhances the accuracy of the EPs in a background and that with all the components of the magnetic field reduces the artifacts at the center of the slices except when all the components of the electric field are close to zero.

Notas sobre processos de criação em currículos
Authors: Santos Cláudia Aparecida
Published: August 2021

O artigo em questão apresenta um panorama da difusão das teorias pós-críticas no campo educacional. Trata-se de um estudo teórico-conceitual que tem por interesse problematizar o “pensamento-identidade” e seu espelhamento nas composições curriculares. Como escopo teórico, acolhem-se as filosofias da diferença, enquanto possibilidade de movimento frente aos modelos majoritários instituídos, sendo Deleuze (2006), Deleuze e Guattari (2010; 2012), e Corazza (2012), em suas elaborações de perspectiva pós-nietzschiana, alguns dos principais interlocutores da discussão. Ainda propõe pensar o currículo como um território a ser construído, que prioriza a diferença ao invés da identidade. Inscrevemos assim um currículo educacional afeito por inflexões, que acontece pelas composições singulares, associações e linhas de fugas.
Na era digital, ‘Filho de peixe, peixinho é’ na Hinterlandia Amazônica?
Authors: Abreu Leonor Farias
Published: August 2021

A formação profissional, nível médio e superior, custou a chegar aos municípios do Amazonas de forma mais abrangente e diversificada, contribuindo para que profissões tradicionais como a de pescador, agricultor, seringueiro, quase que se perpetuassem entre as gerações, tornando uma realidade a expressão popular ‘filho de peixe, peixinho é’, no interior do Estado. Acontecimentos econômicos como a criação do Polo Industrial de Manaus, sociais como as políticas públicas de educação e saúde advindas da Constituição Brasileira de 1988 e a revolução tecnológica desta era digital, impulsionaram formação de mão de obra especializada em outras áreas para atender demandas por novos serviços. Colocamos em discussão a formação profissional que têm chegado aos municípios, provenientes desses acontecimentos, a fim de compreendermos se o dito popular, na era digital, ainda é realidade quando se trata de continuidade (ou não) de profissões de pais pelos filhos na Hinterlândia Amazônica.

O ônus da civilização: histeria e civilização nas teses médicas brasileiras (1838 – 1890)
Authors: Marques de Mello Júnior Fernando
Published: August 2021

O desembarque da corte portuguesa em 1808 iniciou um intenso processo de transformações no Rio de Janeiro. Como sede da monarquia, a urbe recebeu investimentos visando à modernização urbana e à europeização dos costumes locais. Segundo a medicina da época, no entanto, esse processo denominado no período de “civilização” poderia trazer aos habitantes, em especial às mulheres, consequências nefastas, dentre elas a histeria. Assim, o estudo visa a mapear o que escreveram os médicos da época a respeito da histeria e de sua relação com a civilização. Para tanto, analisar-se-ão as teses produzidas nas faculdades de medicina do Rio de Janeiro e da Bahia, únicos centros de produção intelectual do gênero no país, entre 1838, ano de defesa da primeira tese versando sobre a histeria, e 1890, quando é publicada a primeira tese a respeito da doença em homens, alterando, ainda que timidamente, o padrão de teses sobre o tema.
Laboratory evaluation of the possibility of using the eggs of the chestnut moth Cameraria ohridella Deschka & Dimic, 1986 (Lepidoptera: Gracillariidae) to feed the trichogram
Authors: Bashchenko M. , Khudolii A. , Chaika V.
Published: August 2021

Goal. Evaluation of the suitability and eggs of chestnut moth Cameraria ohridella for parasitism and development of trichogramma.

Methods. Laboratory cultures of Trichogramma pintoi Voeg were used for research. and Trichogramma evanescens Westw., which were bred on the eggs of Sitotroga cerealella Oliv. The experiment was performed according to the following scheme: female trichogramma after mating was placed in a test tube in 5 replicates for each species. The tube was closed with a stopper and the sex of individuals under binoculars was checked. In test tubes with trichogram laid strips of paper with one-day eggs of chestnut moth (25 copies.). In 5 replicates and kept in a thermostat (temperature — 24—25°C; relative humidity — 65—67%). The percentage of trichogram revival and the ratio of males to females, life expectancy and fertility of females were determined. Trichogramma individuals, which were fed with grain moth eggs, served as controls. The experiment lasted until the complete death of the trichogram. The obtained results were processed statistically according to standard methods.

Results. A small number of chestnut moth eggs pierced by trichogramma were detected, but embryonic development of the parasite’s eggs was not observed. Comparing the size of the eggs of the chestnut moth with the size of the eggs of the main squamous pests against which different species of trichogramma are effectively used, we can conclude that for the successful development of eggs T. pintoi and T. evanescens chestnut moth eggs are not suitable as feeders. Probably, in terms of size and biological quality, they do not correspond to the parameters of the ecological niche of the hosts of the family Trichogrammatidae.

Conclusions. In the laboratory, it was found that the eggs of the chestnut moth are not suitable for parasitizing the trichogramma of T. pintoi and T. evanescens. The main pests of crops, which are effectively parasitized by different species of trichogramma, have an egg size in the range of 0.4—1.0 mm, while the size of chestnut moth eggs does not exceed 0.27—0.32 mm. It is possible that the size and biological quality of chestnut moth eggs do not meet the parameters of the ecological niche of entomophagous feeders of the family Trichogrammatidae. Further researches with use of various types of a trichogramma, first of all — T. dendrolimi Mats appear actual.

The average annual temperature apparently contributed to the adaptation and the spread of D. virgifera virgifera throughout the region in 2016—2020, and the winter temperature were suitable for the wintering of the eggs.

Conclusions. The western corn rootworm belongs to the quarantine organisms. It needs the use all phytosanitary measures for the containment and restriction of its distribution in the territory of the Ternopil region. According to the average spread of this pest (40—50 km/ year), the further expansion of its population in other regions of Ukraine is predicted. The climatic conditions in the Ternopil region and the available fodder base will promote the development of D. virgifera virgifera.

Authors: Sudak V. , Horbatenko A. , Semenov S. , Kulyk А.
Published: August 2021

Goal. To determine the agrarian and economic efficiency of different technological systems for herbicidal protection of maize depending on the weed harmfulness level and weather conditions.

Methods. Field experiment — for the weeds and maize yield accounting, and calculation method — for determining of the technical and economic efficiency of herbicide systems.

Results. We recorded a significant decrease in the inhibitory effect of soil herbicides without precipitation, at elevated air temperature and hot dry wind in the first 5—7 days after their application. Also we specified the best pre-emergence herbicide Acris SE containing the active ingredients: Dimethenamid P (280 g/l) + Terbuthylazine (250 g/l). The number of weeds was indicated according to the experiment variants before spraying crops and 21 days after the application of toxicants. The technical and economic efficiency of combined (pre-emergence + post-emergence herbicides) and mixture of post-emergence products for protection systems of maize was determined.

Conclusions. Under arid conditions, within 5—7 days after the application of pre-emergence herbicides (in 2018, the average background weed infestation of crops — 37 pcs/m2), the chemical plant protection system based on a tank mixture of post-emergence herbicides was ahead in terms of technical efficiency, yield and profitability grain production: Frontier Optima CE (Dimethenamid, 720 g/l) + Stellar RK (Topramezone, 50 g/l + Dicamba, 160 g/l) + Metolat wetting agent. The manifestation of soil herbicide phytotoxicity in favorable weather (in 2019—2020, background weed infestation of crops 129—147 pcs/m2) was more effective when using a combined system for controlling harmful species in the maize production technology: Dual Gold KE (S-metolachlor, 960 g/l) — before sowing + Stellar RK (Topramezone, 50 g/l + Dicamba, 160 g/l) + Metolat wetting agent — post emergence application. The best pre-emergence chemical product was Acris SE (Dimethenamid P, 280 g/l + Terbuthylazine, 250 g/l).

Authors: Hutianskyi R. , Popov S. , Zuza V. , Kuzmenko N.
Published: August 2021

Goal. To establish the species composition of weeds, their dominant role and determine the type and level of weediness of soybean crops for cultivation in a fixed nine-course stationary, fallow-crop-row rotation and in monoculture in the eastern part of the Forest-Steppe of Ukraine.

Methods. The research was conducted by route surveys in field experiments.

Results. According to the research of 2011—2017, 30 species of weeds and contaminants were found in soybean crops after winter wheat as forecrop in the stationary crop rotation (spring early and late were 60%, winter and biennial were 17%, perennial were 23%), and 18 species (spring early and late were 72%, wintering and biennial were 6%, perennial were 22%) were found for cultivation in monoculture. They belonged to 16 families, the families Asteraceae (9 species), Poaceae (5 species) and Polygonaceae (5 species) were the most represented. The main weeds in soybean crops in crop rotation and monoculture were Echinochloa crus-galli (L.) Roem. et Schult., Chenopodium album L., Cirsium arvense (L.) Scop. and Panicum miliaceum L. In addition to these weeds for growing soybeans in crop rotation were present Setaria glauca (L.) Beauv., Amaranthus retroflexus L., Solanum nigrum L., Polygonum lapathifolium L., Sonchus arvensis L., Convolvulus arvensis L., and in monoculture were Ambrosia artemisiifolia L. and Xanthium strumarium L. Xanthium strumarium L. was the most dominant in the monoculture (43%), and Setaria glauca (L.) Beauv was subdominant in crop rotation (57%), and Echinochloa crus-galli (L.) Roem. and Schult. was subdominant in monoculture (57%). Six complex types of weeds were formed in soybean crops, cereal-dicotyledonous-dicotyledonous-root-sprouting and dicotyledonous-grass-annual-grass-root-sprouting prevailed. For cultivation in crop rotation cereal annual species predominated, and dicotyledonous annuals predominated in monoculture. At the same time, the monoculture had a higher level of weeding than crop rotation, or it was equivalent.

Conclusions. The species composition of weeds in soybean crops in fallow-crop-row rotation and monoculture differs significantly, which should be taken into account by the agronomic service of farms when developing methods of their control.

Authors: Vlasova О. , Sekun M. , Zatserklyana M.
Published: August 2021

Goal. To study the effect of Urea on the properties of working solutions of emulsions and suspensions of chemical and microbiological drugs in plant protection against pests.

Methods. Information-analytical analysis of the effectiveness of joint use of insecticides with Urea. Laboratory experiments on the effect of Urea on: evaporation of droplets from the treated surface; surface tension; reaction of the medium of suspensions and emulsions of working solutions of chemical and microbiological preparations. To do this, in aqueous solutions of insecticides and biological products in concentrations recommended for use in field crops, was added 0.2% aqueous solution of Urea. After a certain period of time, the characteristics of the solutions were determined. An analytical generalization of the change in the properties of working solutions under the influence of urea is carried out.

Results. The information on the possibilities of joint use of insecticides and microbiological preparations with Urea in a single technological process is generalized. Their combination leads to a significant reduction in the evaporation of solution droplets from the treated surface, but does not affect the surface tension and reaction of the solutions.

Conclusions. Urea is an active anti-evaporator of working solutions of insecticides of various nature. Adding it to the solutions of evaporation of drops from the treated surface reduces more than 1.5 times. It does not significantly affect the surface tension and reaction of the solution. This characteristic of the solutions is maintained for 24 hours after preparation.

Formação de mediadores em museus de ciência: diálogos entre a educação formal e não formal
Authors: Gomes Isabel , Cazelli Sibele
Published: August 2021

O presente trabalho analisa processos de formação de mediadores em dois museus de ciência, considerando as relações entre a educação formal e não formal. Tendo como referência os saberes docentes (TARDIF, 2010), verificou-se que, nesses processos, foram enfatizados saberes disciplinares, da formação profissional e da experiência. Constatou-se também que a formação acadêmica em educação contribui para formação de mediadores, na perspectiva dos próprios. Do ponto de vista da educação não formal, o estabelecimento de parcerias com instituições de formação de professores é uma questão premente para uma melhor qualificação dos profissionais de atuam na área, e esse diálogo pode ser frutífero também em sentido inverso, enriquecendo a formação de docentes da educação básica.
