System mapping simplex spaces: facilitating change in L2 educational contexts from a complexity theory perspective
Authors: Fogal Gary G.
Published: March 2022

The claim that educational contexts are dynamic, complex spaces is hardly a novel one. Yet, to date limited explicit treatment in the literature engages L2 classrooms as such. This paucity is partially explained by methodological concerns with investigating diverse and contextually dense places in ways that capture the richness of these environments. While no single method can mitigate this concern, system mapping can help researchers explore system dynamics through a mapping technique that diagrams system variables through the interpretive lens of relevant stakeholders. Stakeholders engage with variables relative to a guiding statement, question, or objective meaningful to the system’s development or maintenance, thus providing insights into interactions across and beyond the conventional teacher–student interface. System mapping is particularly useful for problem solving and developing in-depth understandings of relations across system components. After describing and expanding on system mapping and its uses in education research, this work moves through a sample study in the L2 writing context to demonstrate its utility.
Cx43 upregulation in HUVECs under stretch via TGF-β1 and cytoskeletal network
Authors: Shi Yumeng , Li Xinbo , Yang Jin
Published: March 2022

Many physiological and pathophysiological processes in cells or tissues are involved in mechanical stretch, which induces the gap junction gene expression and cytokine TGF beta changes. However, the underlying mechanisms of the gap junction gene expression remain unknown. Here, we showed that the mRNA and protein levels of Cx43 in human umbilical vein endothelial cells (HUVECs) were significantly increased after 24 h stretch stimulation, and TGF beta1 (not TGF beta2) expression was also upregulated. Administration of TGF beta1 into HUVECs without stretch also induced upregulation of Cx43 expression. However, SB431542, a specific inhibitor of the TGF beta1 receptor, blocked the Cx43 protein upregulation caused by TGF beta1. Further, the increase of Cx43 protein expression under the stretch condition was partially blocked by SB431542; it was also partially blocked by simultaneous administration of anti-TGF beta1 monoclonal neutralization antibody. Importantly, the upregulation of Cx43 induced by stretch was blocked by the administration of actin and microtubule inhibitors, while NEDD4, a key element in mediating Cx43 protein ubiquitination and degradation, was not changed under the stretch condition. In conclusion, upregulation of Cx43 expression under the 24 h stretch condition is mediated via TGF beta1 receptor signaling pathway, and it also involves the actin and microtubule cytoskeletal network.

Published: March 2022

In this article, the Ansys Workbench was used to carry out the finite element analysis of 15 kW wind turbine blades with different damaged positions and different damaged degrees. The results show that the change rate of natural frequency, displacement modes, and strain modes of the blades increased with the increase in the damage degree; the change rate of the natural frequency and displacement modes of the blade decreased with the increase in the speed, while the change rate of the strain modes increased; the change allocation ratio of the displacement modes and strain modes after the damage was more obvious at the damage location than other positions, which can be used to locate the damage position of the blade; the change allocation ratio of strain modes is higher than the change allocation ratio of displacement modes when the damage degree is the same, which means that the recognition effect of the strain modes is more significant than that of the displacement modes.

Published: March 2022

Concrete is one of the most extensively utilized building materials that can be produced, and has the potential to release a significant quantity of CO2into the environment. In this research, through studying lightweight (LW) concrete, attempts are made to produce environmentally friendly LW concrete with high strength using nanosilica rather than part of the cement and waste glass powder instead of aggregates. Recycled polypropylene fibers are used to increase the concrete’s compressive strength and nonlinear behavior. The use of glass powder was 20, 25, and 30% of the weight of aggregates, the consumption of nanosilica was 1, 2, and 3% of the weight of cement, and the consumption of recycled fibers (FORTA Ferro-Green) was 0.5, 1, and 1.5% of the weight of cement. Leca is also utilized as a LW aggregate. According to 7- and 28-day experimentation results and field emission scanning electron microscope analysis, the best sample had 1.5% fiber, 3% nanosilica, and 25% waste glass powder, and had a compressive and tensile strengths of roughly 1.7 and 1.6 times, respectively, those of the control specimen after 28 days. Also, using 3% nanosilica instead of cement can reduce greenhouse gas emissions by about 3%.
The surface modification effect on the interfacial properties of glass fiber-reinforced epoxy: A molecular dynamics study
Authors: Deng Jiangang , Song You , Lan Zhenbo , Xu Zhuolin , Chen Yanming , Yang Bing , Hao Huali
Published: March 2022

In this work, the effect of common functional groups, namely hydroxyl, formyl, carboxyl, and amine groups on the interfacial behavior of surface-modified glass fiber-reinforced epoxy is investigated at molecular scale. The interfacial properties of the epoxy/silica coated with different functional group systems are quantified by performing pulling test using the steered molecular dynamics simulations. It is found that the system with hydroxyl groups has a relatively lower interfacial interaction, exhibiting an adhesive failure mode. When partial hydroxyl groups are replaced by carboxyl, amine, and formyl groups, respectively, the interfacial interactions are increased and these systems exhibit a cohesive failure mode where failure happens in the epoxy close to interface. A relatively higher force is required for the adhesive debonding, while more energy can be dissipated for the cohesive debonding. Because the increased interfacial interactions can prevent the mobility of polymer chains, and delay the propagation of micropores in the matrix, leading to the epoxy matrix with a high ability of energy absorption. Our work provides an insight into how functional groups affect the interface debonding behavior of glass fiber-reinforced epoxy, offering a guideline for control of the interfacial properties of such composites through surface modification techniques.
Molecular dynamics study of deformation mechanism of interfacial microzone of Cu/Al2Cu/Al composites under tension
Authors: Chen Yao , Wang Aiqin , Guo Zishuo , Xie Jingpei
Published: March 2022

The micromechanical behavior of an Al/Al2Cu/Cu multilayer with characteristic crystal orientation during uniaxial tensile deformation was investigated by molecular dynamics. The simulation results showed that under tensile loading, the dislocation nucleates at the Cu/Al2Cu heterogeneous interface and moves toward the Cu layer along the {111} crystal plane. The deformation mechanism is intralayer confinement slip. As the dislocations proliferated, interactions between them occurred; resulting in the formation of insertion stacking faults and deformation twins in the Cu and Al layers. However, no dislocation lines were generated in the Al2Cu layer during tensile deformation. As the load increased, the stress concentration at the Al2Cu/Al interface led to the fracture of the complex. In addition, the microplastic deformation mechanism and mechanical properties of Al/Al2Cu/Cu composites at different temperatures and strain rates were significantly different. These results revealed the microdeformation mechanism of laminated composites containing brittle phases.
THE MULTI-VECTOR NATURE OF HUNGARY’S EASTERN POLICY
Authors:   Institute of Europe, Russian Academy of Sciences, Shishelina Lyubov
Published: March 2022

The author attempts to trace the development of the eastern direction of Hungary’s foreign policy, which received the name «Opening to the East» with the return in 2010 to the Hungarian policy of Viktor Orban’s cabinet. The reason for the study of this aspect was the recent visit of the Hungarian Prime Minister to Moscow on February 1, 2022. In our country, especially after the crisis of 2014, these visits are seen as a breakthrough event, a success of politics and diplomacy. The European Union does not share such a degree of pragmatism of Viktor Orban’s foreign policy, seeing in his trips primarily a political component, which forces him to precede and conclude visits to Moscow with a cascade of meetings with leading Western politicians. The same thing happens before and after the visits of the Russian leader to Budapest. In Hungary, relations with Moscow are viewed exclusively from a pragmatic standpoint, since their economic component allows to achieve real results in overcoming the crisis phenomena affecting the daily lives of citizens (gas, gasoline, electricity, etc.). In addition, the Russian direction is a component of a broader direction of «Opening to the east»” policy. This program, where the Turk element is a significant factor, also separately includes relations with specific Muslim republics of central Russia, with the states of the Caucasus and Central Asia, with Turkey, China, etc.

On December 8, 2021, the new coalition government of Germany began its work, an important area of the country’s foreign policy development is relations with Russia, Germany’s leading partner in the post-Soviet space. In many ways, they determine the parameters of cooperation between the European Union and the Russian Federation and its partners. The SPD, Union 90 / Greens, FDP, during difficult negotiations, agreed on common approaches to cooperation with Russia, which eventually united the value, economic, civil and political «Russian» denominators of the three party election programs. At the same time, the provisions enshrined in the coalition agreement are based on the foundation of bilateral relations built by the last two cabinets of ministers under the leadership of A. Merkel, incl. during 2021, the year that marked the end of the era of the former Chancellor. Just a week after the start of the government, bilateral relations were tested for strength in the political and economic spheres. The new year 2022 began in difficult conditions of escalating confrontation between the collective West, including Germany, and official Moscow. Under these conditions, on January 18, the German and Russian foreign ministers held talks, clarifying their mutual positions on the most important issues on the bilateral and international agenda. On February 15, Russian President V.V. Putin and Chancellor O. Scholz continued to discuss the most important topical issues of cooperation. The author sums up the political and economic results of cooperation between the two leading countries of the European continent in 2021, and also analyzes its prospects in 2022, paying special attention to the role of Germany and the Russian Federation in resolving the intra-Ukrainian conflict.

A Pilot Study of a Hybrid Process Involving In Situ Regenerated Activated Carbon, Membrane Separation and Advanced Oxidation for Water Pollution Abatement
Authors: Sarasidis Vasilis C. , Plakas Konstantinos V. , Karabelas Anastasios J.
Published: March 2022

The assessment of a pilot-scale hybrid system coupling powdered activated carbon (PAC) adsorption with membrane ultrafiltration (UF), in respect of activated carbon regeneration and organic micropollutant removal, was investigated in this study. Field tests with two adsorbents (i.e. a commercial PAC and a PAC-Fe(II) composite), conducted in the premises of Thessaloniki Water Treatment Plant, demonstrated the high efficiency of the combined PAC/UF process. Regeneration efficiencies varying between approximately 95% and 110%, complete diclofenac (DCF) degradation and rather moderate mineralization (TOC removal) rates of up to 47%, can be achieved by UVC/H2O2 or photo-Fenton oxidation after 4 hours of treatment; this performance is attributed to the in situ generation of reactive oxidant species by photolysis of H2O2, which seems to enhance the process effectiveness. Among the two adsorbent materials tested, composite PAC-Fe(II) exhibited a higher DCF adsorption capacity than the original PAC, probably due to the improved chemisorption and/or the electrostatic attractive interactions between the negatively charged DCF molecules and the positively charged iron species, at neutral pH. Furthermore, a rather insignificant effect of PAC-Fe(II) loading on the regeneration efficiency was observed. The advantages of totally controlled H2O2 dosages and short operating times render the hybrid PAC/UF system a promising alternative to conventional and advanced drinking water purification methods.

One of the most important tasks of environmental chemistry is the development of effective methods for the extraction and chemical analysis of highly toxic oxyanions, such as nitrate, phosphate and arsenate. They enter the environment, raw materials and commercial products with waste from chemical and metallurgical industries. This problem can be solved by synthesizing selective materials that absorb anions due to the complementarity of their active centers and ions. The aim of this work is a directed chemical design of silica surface for the construction of sorption active centers with a high affinity for nitrate, orthophosphate, and orthoarsenate anions. Chemical design of β-cyclodextrin-containing supramolecular structures on the surface of granular mesoporous silica gel to obtain sorbents of highly toxic oxyanions was carried out. The structure and surface chemistry of the initial and functionalized silica gels were characterized by means of IR spectroscopy, spectrophotometry, thermogravimetric and chemical analysis, pH metry, low-temperature adsorption-desorption of nitrogen and sorption techniques. The sorption of nitrate, orthophosphate, and orthoarsenate anions from aqueous one- and multicomponent salt solutions was studied as dependent on the time and ion concentration, as well as in the cyclic sorption-desorption mode. The results obtained are interpreted using kinetic models of pseudo-first and pseudo-second order processes and the equilibrium adsorption models of Langmuir and Freundlich. The main characteristics of the specificity and selectivity of the obtained β-cyclodextrin silica gel were calculated. Conclusions are drawn regarding the possibility of using functionalized silica gel for the sorption of oxyanions from water and aqueous solutions, their concentrating, chromatographic separation, and chemical analysis.

It has been shown by the anomalous Hall effect method that upon contact of layers of iron group metal (Ni) and REM oxide (Gd2O3) nanosized films, an increase by 15–35 % in the magnetization of the ferromagnetic metal is observed. Such an increase does not require energy consumption and the use of amplifying equipment, is very promising for nanotechnology. The enhancement of magnetization is due to the appearance in the contact region of the exchange f–d interaction between atoms with empty d– and f–electron shells that are parts of the layers. The exchange interaction stimulates the ordering of the magnetic structure of the ferromagnetic metal and an increase in its magnetization. The possibility of exchange f–d interaction in the region of contact of layers of metals of the iron group and REM oxides was confirmed by the method of electronic paramagnetic resonance in our previous studies. This paper also shows the lack of influence on the growth of magnetization of other possible mechanisms due to the difference in the parameters of the crystal lattice, resistance, magnetic and termomagnetic properties of the contacting layers. A mathematical connection is found of the potential of Hall contacts and additional magnetization stimulated by the exchange f–d interaction. Using this relationship, the mechanism of the effect of an external magnetic field on additional magnetization had revealed. It is shown that this magnetization depends on the ratio of the thicknesses of the Ni and Gd2O3 layers. It has been found that the vector of this magnetization is directed from the Gd2O3 layer to the Ni layer.

Esta pesquisa buscou analisar em que medida as tecnologias digitais (TD) podem ser articuladas nas práticas de ensino de professores de Língua Estrangeira, em uma Escola do Campo, no município de Cáceres-MT. O estudo foi pautado na Teoria dos Sistemas Dinâmicos Complexos que proporcionou uma visão ampliada do funcionamento dinâmico entre as partes e o todo sistêmico da Escola do Campo analisada. A metodologia eleita foi o Estudo de Caso. A análise dos dados elucidou que o uso de tecnologias digitais nesse contexto élimitado, e está atrelado à vários fatores. Os dados apontaram que os professores não dispõem de um prognóstico quantitativo quanto a disponibilidade de equipamentos e recursos logísticos voltados para o acesso à internet dos alunos em suas residências (fazendas, comunidades, assentamentos). Este fato dificulta a promoção de práticas mediadas por TD e, consequentemente, o trabalho com os letramentos digitais. Além disso, a análise dos dados apontou ainda que a concepção de Tecnologias Digitais dos professores está estreitamente relacionada ao acesso à internet. Ou seja, para os professores, as possibilidades de apropriação das tecnologias digitais não fazem nenhum sentido se estiverem desconectadas da internet. Esse entendimento revela um desalinhamento com a Base Nacional Comum Curricular (BNCC) que orienta as práticas contemporânea de ensino e de aprendizagem no Brasil.

Published: March 2022

Partindo do imaginário coletivo de que a escola pública não é o lugar de um ensino eficiente da Língua Inglesa, este trabalho objetiva abordar os caminhos curriculares percorridos por tal idioma como disciplina na educação pública brasileira, traçando uma linha temporal dentro do arcabouço histórico-normativo, desde quando passou a ser ensinada formalmente aos brasileiros até a atualidade. Com base nas pesquisas bibliográfica e documental de caráter qualitativo, além de referencial teórico ancorado na área de ensino de Língua Inglesa, foram analisados documentos da época do Brasil Imperial e do Brasil República, antes e depois do advento das Leis de Diretrizes e Bases. Ao fim, entende-se que a intermitência entre a eletividade e a obrigatoriedade no texto legal/normativo pode levar ao entendimento geral de que a educação pública não assegura o ensino efetivo de Inglês.

Published: March 2022

Several Lactobacillus species are accepted as microorganisms with Qualified Presumption of Safety (QPS) in the EFSA’s list. One of them, Lactobacillus plantarum is a widely distributed species with a proven probiotic potential and technological relevance. In addition, every strain must complete several requirements, before implementation. Antibiotic susceptibility is one of EFSA’s important criteria regarding the safety of probiotics. The reason is to avoid any possibility of antibiotic resistance genes transfer to opportunistic pathogens in the gut. In the present study 14 Lactobacillus plantarum strains were assessed for susceptibility to 21 antibiotics from different groups. A high number of resistant strains was determined toward 12 antibiotics (penicillins – penicillin, piperacillin; IIIth generation cephalosporins – cefotaxime, ceftriaxone, ceftazidime; glycopeptides – vancomycin; tetracyclines – tetracycline; aminoglycosides – gentamicin; macrolides – clarithromycin; quinolones – nalidixic acid, ciprofloxacin, levofloxacin). Concerning the other tested antibiotics, strain-specific antibiotic-sensitivity patterns were observed. Antibiotic resistance was also discussed as an advantage in the selection of probiotic strains, however only when it is not transferable. Estimated susceptibility patterns of some of tested candidate probiotic strains are also important, considering the use of the latter as agents accompanying antibiotic therapy

Published: March 2022

The present study was undertaken to evaluate the beneficial effects of a mycotoxin binder (Mycotox NG 0.05%) in 40 day-old Toulouse geese from both sexes with experimental aflatoxicosis. The birds were reared from day one to 42 days of age on deep litter system and divided into four groups. Normal feed free of aflatoxin (AFB1), was given to the control (Group 1). The feed of Group 2 was supplemented with 0.5 g/kg Mycotox NG, aflatoxin (0.5 mg/kg feed) was supplemented to the feed of Group 3 and Mycotox NG (0.05%) + 0.5 mg/kg AFB1 - to the feed of Group 4. Production parameters (body weight gain, feed intake, feed conversion) and relative organ weights were recorded. The results showed that the total feed intake, final live weight of Mycotox NG + AFB1 treated birds (Group 4) at 6 weeks of age were significantly increased (P<0.01) as compared to birds treated only with AFB1 (Group 3). The total feed conversion ratio of the group given AFB1 only (Group 3) at 6 weeks of age was significantly increased (P<0.01) compared to controls while in Mycotox Ng + AFB1 treated birds (Group-4) it was significantly increased (P<0.01) by post treatment week 1 vs controls, but not as compared to birds treated with AFB1 alone. There was a significant increase in relative weights of liver, kidneys, spleen, heart, pancreas, proventriculus and gizzard in birds fed only aflatoxin (Group 3). The co-administration of Mycotox NG (0.5 g/kg feed) with AFB1 (Group 4) reduced the relative weights of thymus and bursa of Fabricius. The study concluded that dietary supplementation of Mycotox NG could partially neutralise aflatoxicity in geese.

Published: March 2022

Pyrochemical reprocessing is a potential route for the reprocessing of fuels from next-generation reactors. Lanthanide fission products may be separated from the reprocessing salt by a number of methods; however, salts may be entrained in the resultant product. This work demonstrates conceptual monazite glass-ceramic wasteforms based on the quarternary (100−x)(10Na2O–36Fe2O3–54P2O5)–xLa2O3 (x = 5, 10, 15), with La2O3 as a surrogate for the lanthanide oxide waste stream. Samples were produced by the melting of La2O3 with a sodium-iron-phosphate glass frit and characterised by XRD and SEM–EDX. The monazite phase was successfully formed at all waste loadings with clear segregation of La to the crystalline phase; however, high La2O3 loading (>10 mol%) was found to destabilise the glass system resulting in gross crystallisation. These initial results indicate that monazite glass-ceramics are promising wasteforms for this waste stream.
