Published: August 2022

Paulownia tomentosa (Thunb.) Steud is a drought-resistant, low-maintenance and fast-growing energy crop that can withstand a wide range of climatic conditions, provides a high biomass yield (approximately 50 t DM ha−1 yr−1), and develops successfully in contaminated sites. In Kazakhstan, there are many historically contaminated sites polluted by a mixture of xenobiotics of organic and inorganic origin that need to be revitalised. Pilot-scale research evaluated the potential of P. tomentosa for the phytoremediation of soils historically contaminated with organochlorine pesticides (OCPs) and toxic trace elements (TTEs) to minimise their impact on the environment. Targeted soils from the obsolete pesticide stockpiles located in three villages of Talgar district, Almaty region, Kazakhstan, i.e., Amangeldy (soil A), Beskainar (soil B), and Kyzylkairat (soil K), were subjected to research. Twenty OCPs and eight TTEs (As, Cr, Co, Ni, Cu, Zn, Cd, and Pb) were detected in the soils. The phytoremediation potential of P. tomentosa was investigated for OCPs whose concentrations in the soils were significantly different (aldrin, endosulfans, endrin aldehyde, HCB, heptachlor, hexabromobenzene, keltan, methoxychlor, and γ-HCH) and for TTEs (Cu, Zn, and Cd) whose concentrations exceeded maximum permissible concentrations. Bioconcentration (BCF) and translocation (TLF) factors were used as indicators of the phytoremediation process. It was ensured that the uptake and translocation of contaminants by P. tomentosa was highly variable and depended on their properties and concentrations in soil. Besides the ability to bioconcentrate Cr, Ni, and Cu, P. tomentosa demonstrated very encouraging results in the accumulation of endosulfans, keltan, and methoxychlor and the phytoextraction of γ-HCH (TLFs of 1.9–9.9) and HCB (BCFs of 197–571). The results of the pilot trials support the need to further investigate the potential of P. tomentosa for phytoremediation on a field scale.

Published: August 2022

Urban areas’ pollution, which is owing to rapid urbanization and industrialization, is one of the most critical issues in densely populated cities such as Cairo. The concentrations and the spatial distribution of fourteen potentially toxic elements (PTEs) in household dust were investigated in Cairo City, Egypt. PTE exposure and human health risk were assessed using the USEPA’s exposure model and guidelines. The levels of As, Cd, Cr, Cu, Hg, Mo, Ni, Pb, and Zn surpassed the background values. Contamination factor index revealed that contamination levels are in the sequence Cd > Hg > Zn > Pb > Cu > As > Mo > Ni > Cr > Co > V > Mn > Fe > Al. The degree of contamination ranges from considerably to very high pollution. Elevated PTE concentrations in Cairo’s household dust may be due to heavy traffic emissions and industrial activities. The calculated noncarcinogenic risk for adults falls within the safe limit, while those for children exceed that limit in some sites. Cairo residents are at cancer risk owing to prolonged exposure to the indoor dust in their homes. A quick and targeted plan must be implemented to mitigate these risks.

The locusts Oedales asiaticus (Bey-Bienko) and Myrmeleotettix palpalis (Zubovski) (Orthoptera Acrididae) and the leaf beetle Galeruca daurica (Joannis) (Coleoptera, Chrysomelidae) are economically devastating insect species in the desert steppes of Northern China. Control is mainly and frequently dependent on highly toxic chemicals. To date, there have been no complete and comprehensive reports of insecticide applications to these key pests. In this study, laboratory bioassays were carried out to determine and compare the toxicity of twelve insecticides to three outbreaking insects, O. asiaticus, M. palpalis, and G. daurica, from three typical desert steppe regions, SZWQ, XHQ and WLTQQ, respectively. The responses of the two locust species and the leaf beetle were evaluated by topical application and leaf dip bioassay techniques across a range of concentrations to develop dosage–mortality regressions. The insecticides tested included six chemical insecticides (β-cypermethrin, imidacloprid, phoxim, λ-cyhalothrin, methomyl, chlorantraniliprole) and six biogenic insecticides (spinosad, avermectin, rotenone, matrine, azadiracthin, and methoxyfenozide). The results showed that phoxim, λ-cyhalothrin, β-cypermethrin and spinosad showed highly toxic activity to O.asiaticus, M. palpalis, and G. daurica, while methonyl, chlorantraniliprole, and rotenone were moderately toxic to both locust species and the leaf beetle. The LC50 values of matrine, azadiractin, and avermectin were more than 1 μg a.i./adult for O. asiaticus and M. palpalis, the LC50 values of which were higher 2 g/L for G. daurica. Our findings complement information from previous similar studies and will inform future studies relating to the control of outbreaking insects, such as O.asiaticus, M. palpalis, and G. daurica in desert steppes of northern China. This study is also expected to provide basic data on the use of chemical and biogenic insecticides for application in desert steppes.

Contamination of edible oils with aflatoxins (AFs) is a universal issue due to the detrimental effects of aflatoxins on human health and the fact that edible oils are a major source of fungal growth, particularly storage fungi (Aspergillus sp.). The objective of this study was to assess aflatoxin B1 (AFB1) in edible oil used in fried food in order to determine the risk of cancer from AFB1 exposure through cooked food using the FAO/WHO’s and EFSA’s margin of exposure (MOE) quantitative liver cancer risk approaches. Using Mycosep 226 columns and HPLC-FLD, 100 samples of cooking oils (soybean, canola, and sunflower oil) from different food points were analyzed for contamination with aflatoxins. Of all the samples tested, 89% were positive for total aflatoxins and AFB1, with 65% indicating AF concentrations beyond permitted levels. Canola oil was found to contain higher levels of AFB1 and AFs than soybean and sunflower oil. Almost 71 percent of canola oil samples (range of 54.4–281.1 µg/kg) were contaminated with AF levels higher than the proposed limits of the European Union (20 µg/kg). The consumption of canola oil samples used in fried foods had MOE values that were significantly lower as compared to sunflower and soybean oils, indicating that risk reduction is feasible. Additionally, compared to soybean and sunflower oil, canola oil exhibited a greater threat of liver cancer cases linked to AFB1 exposure (17.13 per 100,000 males over 35 and 10.93 per 100,000 females over 35). Using a quantitative liver cancer approach, health risk valuation demonstrated that males and females over the age of 35 are at significant risk of developing liver cancer. The health risk assessment exposed that the males and female over the age of 35 are at considerable risk of liver cancer by using a quantitative liver cancer approach. The innovation of this study lies in the fact that no such study is reported related to liver cancer risk evaluation accompanied with AFB1 exposure from consumed edible oil. As a result, a national strategy must be developed to solve this problem so that edible oil products are subjected to severe regulatory examination.

Despite recovering from the acute phase of coronavirus disease (COVID-19), many patients report continuing symptoms that most commonly include fatigue, cough, neurologic problems, hair loss, headache, and musculoskeletal pain, a condition termed long-COVID syndrome. Neither its etiopathogenesis, nor its clinical presentation or risk factors are fully understood. Therefore, the purpose of this study was to retrospectively evaluate the most common symptoms of long-COVID among patients from the STOP COVID registry of the PoLoCOV study, and to search for risk factors for development of the syndrome. The registry includes patients who presented to the medical center for persistent clinical symptoms following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The analysis included data from initial presentation and at three-month follow-up. Of the 2218 patients, 1569 (70.7%) reported having at least one symptom classified as long-COVID syndrome three months after recovery from the initial SARS-CoV-2 infection. The most common symptoms included chronic fatigue (35.6%\), cough (23.0%), and a set of neurological symptoms referred to as brain fog (12.1%). Risk factors for developing long-COVID syndrome included female gender (odds ratio [OR]: 1.48, 95% confidence intervals [CI] [1.19–1.84]), severe COVID-19 (OR: 1.56, CI: 1.00–2.42), dyspnea (OR: 1.31, CI: 1.02–1.69), and chest pain (OR: 1.48, CI: 1.14–1.92). Long-COVID syndrome represents a significant clinical and social problem. The most common clinical manifestations are chronic fatigue, cough, and brain fog. Given the still-limited knowledge of long-COVID syndrome, further research and observation are needed to better understand the mechanisms and risk factors of the disease.

The highly pathogenic avian influenza (HPAI) H5N8 virus was first detected in Egypt in late 2016. Since then, the virus has spread rapidly among different poultry sectors, becoming the dominant HPAI H5 subtype reported in Egypt. Different genotypes of the HPAI H5N8 virus were reported in Egypt; however, the geographic patterns and molecular evolution of the Egyptian HPAI H5N8 viruses are still unclear. Here, extensive epidemiological surveillance was conducted, including more than half a million samples collected from different poultry sectors (farms/backyards/live bird markets) from all governorates in Egypt during 2019–2021. In addition, genetic characterization and evolutionary analyses were performed using 47 selected positive H5N8 isolates obtained during the same period. The result of the conducted surveillance showed that HPAI H5N8 viruses of clade 2.3.4.4b continue to circulate in different locations in Egypt, with an obvious seasonal pattern, and no further detection of the HPAI H5N1 virus of clade 2.2.1.2 was observed in the poultry population during 2019–2021. In addition, phylogenetic and Bayesian analyses revealed that two major genotypes (G5 and G6) of HPAI H5N8 viruses were continually expanding among the poultry sectors in Egypt. Notably, molecular dating analysis suggested that the Egyptian HPAI H5N8 virus is the potential ancestral viruses of the European H5N8 viruses of 2020–2021. In summary, the data of this study highlight the current epidemiology, diversity, and evolution of HPAI H5N8 viruses in Egypt and call for continuous monitoring of the genetic features of the avian influenza viruses in Egypt.

Microbial resistance is a global health problem that will increase over time. Advances in insect antimicrobial peptides (AMPs) offer a powerful new approach to combat antimicrobial resistance. Invertebrates represent a rich group of animals for the discovery of new antimicrobial agents due to their high diversity and the presence of adaptive immunity or “immune priming”. Here, we report a priming approach for Tenebrio molitor that simulates natural infection via the oral route. This oral administration has the advantage of minimizing the stress caused by conventional priming techniques and could be a viable method for mealworm immunity studies. When using inactivated microorganisms for oral priming, our results showed an increased survival of T. molitor larvae after exposure to various pathogens. This finding was consistent with the induction of antimicrobial activity in the hemolymph of primed larvae. Interestingly, the hemolymph of larvae orally primed with Escherichia coli showed constitutive activity against Staphylococcus aureus and heterologous activity for other Gram-negative bacteria, such as Salmonella enterica. The priming of T. molitor is generally performed via injection of the microorganism. To our knowledge, this is the first report describing the oral administration of heat-inactivated microorganisms for priming mealworms. This technique has the advantage of reducing the stress that occurs with the conventional methods for priming vertebrates.

Background: This study explored awareness and adhesion of parents to the recommendations for influenza vaccination for their children. Methods: This cross-sectional study was conducted from March to June 2022 among parents of 6 months–6 years-old children in Southern Italy. Results: Only 22.1% of parents were aware that influenza vaccination was recommended for healthy children, and 31.8% reported at least one influenza vaccination in the four influenza seasons from 2018/2019 to 2021/2022. Adherence was higher among parents who had received influenza vaccination at least once, who knew the main childhood vaccinations, who knew that influenza can be prevented, that influenza vaccination is recommended for healthy children, who believe that it is useful, and who have been informed about it by physicians. Willingness to vaccinate their children in the upcoming season was 48.6% and was higher among parents who had vaccinated their children at least once, believed that influenza vaccination protects against severe complications, believed that it is useful, and that it is not better for children to acquire immunization through illness than through vaccination. Conclusions: These findings suggest that efforts should be devoted to educating parents on the risks associated with the disease and the benefits of the vaccine.
The National Strategies for and Challenges in Infection Prevention and Control of the Healthcare System in the Kingdom of Saudi Arabia (Review Study)
Authors: Alslamah Thamer , Abalkhail Adil
Published: August 2022

Healthcare-associated infections (HAIs) lead to considerable morbidity. Prolonged hospital HAIs, also known as hospital infections or nosocomial infections, refer to infectious diseases that occur within 48 h of hospital admission, within three days of discharge or 30 days after having received healthcare. A total of 39 government-owned hospitals with a total of 10,822 beds providing the majority (59.9%) of Saudi Arabian healthcare were analyzed. Medicare and Medicaid use hospital data to track hospital performance on matters pertaining to IPC. In addition, many hospitals have limited capacity with which to develop the core components required to build an effective IPC programme. Hajj has been associated with the increased prevalence and spread of infectious diseases. These factors include changes in human demographics and behaviour, the effect of new technologies and industries, an increase in international travel and commerce, and breakdown resulting from public health measures. Overall public health service expenditure originates from the administration and services that are provided free of charge to all Saudi citizens.

Recent efforts have been directed toward the development of universal influenza vaccines inducing broadly neutralizing antibodies to conserved antigenic supersites of Hemagglutinin (HA). Although several studies raise the importance of glycosylation in HA antigen design, whether this theory can be widely confirmed remains unclear; which influenza HA with an altered glycosylation profile could impact the amplitude and focus of the host immune response. Here, we evaluated the characteristics and efficacy of deglycosylated modified HA proteins, including monoglycosylated HA (HAmg), unglycosylated HA (HAug), and fully glycosylated HA (HAfg), without treatment with H3N2 Wisconsin/67/2005. Our results showed that HAug could induce a cross-strain protective immune response in mice against both H3N2 and H7N9 subtypes with better antibody-dependent cellular cytotoxicity (ADCC) than the HAmg- and HAfg-immunized groups, which suggested that highly conserved epitopes that were masked by surface glycosylation may be exposed and thus promote the induction of broad antibodies that recognize the hidden epitopes. This strategy may also supplement the direction of deglycosylated modified HA for universal influenza vaccines.

Published: August 2022

In order to improve the efficiency of electrified vehicle drives, various predictive energy management strategies (driving strategies) have been developed. This article presents the extension of a generic prediction approach already proposed in a previous paper, which allows a robust forecasting of all traction torque-relevant variables for such strategies. The extension primarily includes the proper utilization of map data in the case of an a priori known route. Approaches from Artificial Intelligence (AI) have proven to be effective for such proposals. With regard to this, Recurrent Neural Networks (RNN) are to be preferred over Feed-Forward Neural Networks (FNN). First, preprocessing is described in detail including a wide overview of both calculating the relevant quantities from global navigation satellite system (GNSS) data in several steps and matching these with data from the chosen map provider. Next, an RNN including Long Short-Term Memory (LSTM) cells in an Encoder–Decoder configuration and a regular FNN are trained and applied. The models are used to forecast real driving profiles over different time horizons, both including and excluding map data in the model. Afterwards, a comparison is presented, including a quantitative and a qualitative analysis. The accuracy of the predictions is therefore assessed using Root Mean Square Error (RMSE) computations and analyses in the time domain. The results show a significant improvement in velocity prediction with LSTMs including map data.
Histological Study of Glandular Variability in the Skin of the Natterjack Toad—Epidalea calamita (Laurenti, 1768)—Used in Spanish Historical Ethnoveterinary Medicine and Ethnomedicine

Published: August 2022

Common toads have been used since ancient times for remedies and thus constitute excellent biological material for pharmacological and natural product research. According to the results of a previous analysis of the therapeutic use of amphibians in Spain, we decided to carry out a histological study that provides a complementary view of their ethnopharmacology, through the natterjack toad (Epidalea calamita). This species possesses a characteristic integument, where the parotoid glands stand out, and it has been used in different ethnoveterinary and ethnomedical practices. This histological study of their glandular variability allow us to understand the stages through which the animal synthesises and stores a heterogeneous glandular content according to the areas of the body and the functional moment of the glands. To study tegumentary cytology, a high-resolution, plastic embedding, semi-thin (1 micron) section method was applied. Up to 20 skin patches sampled from the dorsal and ventral sides were processed from the two adult specimens collected, which were roadkill. Serous/venom glands display a genetic and biochemical complexity, leading to a cocktail that remains stored (and perhaps changes over time) until extrusion, but mucous glands, working continuously to produce a surface protection layer, also produce a set of active protein (and other) substances that dissolve into mucous material, making a biologically active covering. This study provides a better understanding of the use of traditional remedies in ethnoveterinary medicine.

Published: August 2022

This study analyses the aortic wall structure in nine cetacean species with deep diving habits belonging to four Odontoceti families: Ziphiidae, Kogiidae, Physteridae, and Delphinidae. Samples of ascending, thoracic and abdominal aorta were processed for histological and morphometric studies. The elastic component was higher in the proximal aortic segments, and the muscular elements increased distally in all cases. Morphometric analyses showed that all families presented a decrease in the thickness of the arterial wall and the tunica media along the aorta. The reduction was dramatic between ascending and thoracic aorta in the Physeteridae specimens; meanwhile, the other three families showed a more uniform decrease between the ascending, thoracic and abdominal aorta. The decline was not correlated with a reduced elastic or lamellar unit thickness but with a loss of lamellar units. The organization of the elements in the aortic wall did not show essential modifications between the four families, resembling the structure described previously in the shallow and intermediate diving dolphins. Our findings support that the difference in the morphometric characteristics of the different segments in the aortic wall is likely related to the diving habit more than the absolutes values of any other parameter.

Published: August 2022

Phytoindication properties of Robinia pseudoacacia L. in the conditions of Kamyanets-Podilsky were analyzed. Data on the role of plants in the ecological stabilization of the urban environment are given. It is noted that woody plants have a number of advantages over others, as they enrich and purify the air throughout the year, their large area of photosynthetic organs allows you to effectively absorb toxic substances from the environment and play an assimilative role. In addition, woody plants are studied in phytoindication studies. Information about the object of study, its contradictory significance due to invasiveness and large economic and social role is provided. To analyze the phytoindication properties of R. pseudoacacia in the conditions of Kamyanets-Podilsky, we selected seven experimental sites with different anthropogenic loads, including traffic intensity. The area of leaves, the number of beans on the model branch, the length and width of the beans, the morphometric parameters of the seeds (length and width), the number of seeds in the bean and the weight of the seeds were chosen for the studied parameters. It is shown that R. pseudoacacia plants in different places of growth of KamyanetsPodilsky differ in morphometric parameters. It was found that with deteriorating conditions, the area of leaves, the number of fruits on the model branch, the length and width of beans, seed weight and its linear size decreases. We propose to use the studied parameters in bioindication studies to assess the state of the environment.

A pandemia e a inerente alteração de comportamentos, a par da pouca previsibilidade, conceberam maiores níveis de sintomas de ansiedade na população. O isolamento social foi proposto pelos governos locais como medida de saúde pública fundamental para controle da disseminação do Covid-19. Apesar de ser uma das medidas mais eficazes no combate à propagação da pandemia, o distanciamento pode ter influências sociais e psicológicas diretas e indiretas na saúde mental da população. Investigar os sintomas de ansiedade e fatores associados na população adulta durante a pandemia da Covid-19 no estado do Ceará, Nordeste do Brasil. Trata-se de um estudo descritivo com caráter retrospectivo, no qual participaram da pesquisa 214 sujeitos (44,4% residentes de Fortaleza, 43,9% da Região Metropolitana e 11,7% residentes de outras cidades). Para a coleta de dados foi utilizado o Inventario de Beck - BAI, disponibilizado de forma eletrônica através do Google Forms® e analisados pela estatística descritiva e regressão logística. Identificou-se que a maioria (58,87%) dos entrevistados apresentavam sintomas de ansiedade. Os sintomas de ansiedade mostraram-se relacionados aos indivíduos mais jovens 18-23 anos (OR = 3,03; IC: 1,17-7,80), que não praticavam atividade física (OR = 2,14; IC: 1,14- 4,02) e que pararam de praticar atividade física durante o lockdown (OR = 2.38; IC: 1,20 - 4,71). Os participantes do presente estudo apresentaram sintomas de ansiedade leve, moderado e severo e os fatores associados foram idade, não praticar atividade física e ter parado de praticar atividade física durante o período de lockdown.

Relato de caso: esplenectomia em cadela com Sarcoma de células Fusiformes em baço
Authors: Silva Tatiane Fatima Eing Mello e
Published: August 2022

Os tumores esplênicos podem acometer vários mamíferos, independentemente da raça ou sexo, como cães e gatos, tendo maior incidência nos idosos. Na rotina clínica são comuns alterações identificadas em pequenos animais com tumores em baço, sendo a esplenectomia o tratamento cirúrgico inicial após o diagnosticado. Para auxiliar no diagnóstico exames de imagem são mais eficazes, como a ultrassonografia que é mais utilizada porque identifica melhor as medidas, formas e metástases dos tumores abdominais. O diagnóstico prévio é reservado pois os sinais clínicos são inespecíficos e geralmente ocorrem tardiamente. Alguns sinais clínicos podem ser:  anorexia; aumento de volume abdominal; letargia; depressão; êmese; choque hipovolêmico ou hemorragias na cavidade abdominal decorrentes de rupturas ou necrose do baço e órgãos adjacentes. Nesse relato será descrito o caso ocorrido com uma cadela de 10 de idade com alteração esplênica. No exame físico foi identificado massa tumoral em região topográfica de baço e identificado liquido intersticial, confirmado por exame ultrassonográfico. Devido ao quadro clínico da paciente foi realizada cirurgia de emergência, logo após o diagnóstico, devido ao grande risco de óbito. O objetivo deste relato de caso foi demonstrar o diagnóstico e o tratamento para resolução de tumores malignos acometendo o baço. Outrossim, ressaltar a importância do diagnóstico precoce, sobretudo em animais na fase adula e senil, a partir da realização de exames clínicos rotineiros: como hemograma; bioquímicos; exames de imagem, em razão do aparecimento tardio dos sinais clínicos.

A medicina veterinária vem evoluindo cada dia mais acerca de novos tratamentos e técnicas, que auxiliam o médico veterinário em sua rotina e ajudam os seus pacientes a receberem o que há de mais novo em tratamento para suas patologias e enfermidades. Dentre esses tratamentos e evoluções, destaca-se a ozonioterapia, técnica que faz uso da combinação ozônio e oxigênio, que tem se tornado uma grande aliada no tratamento de diversas doenças, por apresentar resultados bastante satisfatórios. Em meio a essas doenças, destacam-se a Diabetes Mellitus tipos I e II, doença endócrina de origem autoimune ou adquirida, que tem por característica o aumento de açúcar circulante na corrente sanguínea conhecida como hiperglicemia. O paciente diabético por sua vez, enfrenta dificuldade na cicatrização de feridas devido a sua condição fisiológica, e a ozonioterapia vem auxiliando esses pacientes na evolução de seu tratamento.  Por isso objetivou-se compreender como a ozonioterapia pode contribuir para a cicatrização das feridas de cães diabéticos. Utilizou-se uma metodologia em foram selecionados trabalhos com temas relacionados ao assunto. Os artigos foram publicados no intervalo de 2017 a 2022 e serviram para embasar o desenvolvimento do trabalho. Para tanto se usou buscadores como Google acadêmico e Scielo. Percebeu-se que a ozonioterapia pode trazer bons resultados no processo de cicatrização da ferida em cães diabéticos, mas deve-se ser usada como tratamento complementar.

Este capítulo apresenta os resultados e suas análises frutos de uma intervenção sobre a questão de gênero em disciplina do curso de Pedagogia, que tem como especificidade o estágio curricular em Educação Especial. A temática justifica-se pela demanda social do enfrentamento ao preconceito, discriminação e violência das mais diferentes ordens, em função das questões de gênero, o que não difere nos espaços escolares. O problema da pesquisa: Como a discussão de gênero está presente nos planos de aula propostos por licenciandos do Curso Pedagogia? O recorte deste capítulo são as produções dos discentes na elaboração de planos de ensino que tivessem como eixo de análise a questão de gênero, esses planos foram apresentados pelos licenciandos como conclusão à sequência de oficinas de sensibilização e aprofundamento realizadas ao decorrer da disciplina. A metodologia consiste em uma pesquisa intervenção realizada em três etapas: 1) o desenvolvimento de oficinas, 2) a elaboração de planos de aula pelos licenciandos a partir das oficinas, e 3) a análise dos produtos. Nos planos de aula apareceram variadas formas de como tematizar a questão de “gênero” na escola sem necessariamente ser uma aula sobre o tema. Foi destacado como a temática de gênero faz parte do cotidiano e não pode ser dissociada do ambiente escolar. Ficou evidente a importância dos estudos de gênero na formação inicial de professores, uma vez que tal discussão se apresenta como um instrumento essencial na busca de justiça, direitos e equidade.

Neste artigo apresenta-se um estudo exploratório, com recurso a um estudo de caso selecionado através de uma amostragem por conveniência realizado numa turma de jovens com deficiência e/ou Necessidades Educativas Especiais (NEE) no colégio de St. Piers, Young Epilepsy (YE), Inglaterra durante o ano letivo 2020-2021 (ano da pandemia COVID-19). Pretendeu-se compreender a importância da plataforma de gestão educativa Earwig Academic no quotidiano destes estudantes, recorrendo-se à monotorização do seu desempenho em quatro sessões no colégio. Das opções formativas oferecidas em St. Piers que se encontram organizadas em quatro áreas: a) Competências funcionais; b) Estudos vocacionais; c) Atividades de enriquecimento e d) A vida depois do Colégio, selecionou-se as sessões de Competências Funcionais, Culinária, Desporto e Fazenda para também se compreender a importância da diferenciação educativa no desenvolvimento dos estudantes. A recolha de dados foi realizada através da observação não participante e participante, conversas formais e informais, com recurso a evidências fotográficas, folhas de exercícios e notas de campo que ajudaram na monotorização do estudante na Earwig Academic. Esta análise qualitativa permitiu compreender: a) as fragilidades dos ambientes online utilizados; b) a importância da diferenciação educativa para colmatar as dificuldades identificadas e c) a relevância de uma equipa educativa capacitada para o sucesso educativo. A importância do recurso a uma plataforma de aprendizagem, de base construtivista como a Esybee é clara. Este sistema de suporte multicamadas (Multi-Tiered System of Support), com recurso à resposta à intervenção (response to intervention - RTI), representa uma medida importante na promoção da educação de qualidade.

A new chiral aggregate-based tool for asymmetric synthesis has been developed by taking advantage of chiral aggregates of GAP (Group-Assisted Purification) reagents,
N
-phosphonyl imines. This tool was proven to be successful in the asymmetric GAP synthesis of functionalized 2,3-dihydrobenzofurans by reacting salicyl
N
-phosphonyl imines with dialkyl bromomalonates in various cosolvent systems. The chiral induction can be controlled by differentiating between two asymmetric directions simply by changing the ratios of cosolvents which are commonly adopted in AIE (aggregation-induced emission) systems. The formation of chiral aggregates was witnessed by a new analytical tool—aggregation-induced polarization (AIP). The present synthetic method will be broadly extended for general organic synthesis, particularly, for asymmetric synthesis and asymmetric catalysis in the future.

The oxygen-converter process is accompanied by the release of a significant amount of off-gases, that under the conditions of postcombustion form a torch over the neck of the converter. Change the torch nature corresponds the peculiarities of the heat blowing. However, it is difficult to register and analyze the torch due to the significant temperature above the neck of the unit and the large amount of dust released during the blowing. The paper presents the results of physical modeling of methods of registration of physical indicators of flame, simulating a single flare, such as heat transfer from a gas torch, luminosity (brightness) in the ultraviolet, visible and infrared spectra and electrical characteristics of the torch. It was indicated the feasibility of using the measurement of electrical characteristics of the gas flare as a parameter to control the process (namely the difference of natural potentials), such as postcombustion, due to efficiency determination, the lack of significant impact on the accuracy of measurement of excess temperature and the degree of dust. Testing of this method on a high-temperature model showed compliance with the registered electrical characteristics of the system “blowing lance - metal bath-body of the unit” of a number of processes that occur during the blowing in the volume of the unit. By comparing the obtained measured indicators with the experimentally established indicators according to the parameters of technology and limit values, it is possible to draw conclusions, depending on their deviation, about the necessity, for example, change the position of the lance to achieve the desired result or perform other corrective operations and achieve the best technological results of the metal smelting.
ON DETERMINATION OF RATIONAL TEMPERATURES OF SELF-TEMPERING OF BAR REINFORCEMENT FROM HIGH-CARBON STEELS DURING THERMAL HARDENING
Authors: Parusov Eduard , Chuiko Ihor , Parusov Oleh , Sagura Lyudmyla
Published: August 2022

The effect of self-tempering temperatures during thermal hardening and separate heating on the change in the mechanical properties of rebar made of steels C56D, C70D, C80D and C82D (EN 16120-2:2017) was studied. In general, reinforcing bars before and after heating complies with the requirements of the DSTU 3760:2019 standard, which apply to steel of strength classes A800 and A1000. Rational self-tempering temperature intervals have been established for guaranteed production of reinforcing bars of strength classes A800 and A1000 with the prevention of cracking. With an increase in the carbon content, it is necessary to increase the self-tempering temperature of rolled products, which accordingly reduces the level of steel hardening. In the production of rebar, strict control over the temperature-time conditions of water cooling and the actual values of self-tempering temperatures should be observed due to the fact that high-carbon steels are very sensitive to cracking when using intensive water cooling modes.

Published: August 2022

The prediction of mechanical properties is very important task in the quality control of steel, which is one of the world's most important engineering and construction materials. To the main factors affecting the mechanical properties of steel belongs thermomechanical treatment and the chemical composition. The chemical composition may vary for a special high-strength low-alloy steel to meet certain mechanical property requirements. This paper presents a machine learning approach for prediction of tensile strength of structural steels. A single hidden layer Artificial Neural Network (ANN) model was developed and validated based on industrial data set. The ANN model inputs were parameters of interatomic interaction, characterizing the chemical and structural state of the melt. The modeling results showed that the ANN model might be an attractive and useful tool for forecasting the mechanical properties of steel. It offers also a potential for the further derivative free optimization of chemical composition for special quality criteria.
REACHING THE HIGH LEVEL OF MECHANICAL PROPERTIES IN THIN-WALLED TUBULAR PRODUCTS AND SHAPES OF HIGH STRENGTH STEELS

To produce thin-walled tubular products and profiles with high level of mechanical properties, it is advisable to use two-phase (DP) steel, which has a ferritic-martensitic microstructure. The main technological element in the production of such products, which provides a combination of high strength and ductility is a special heat treatment in the temperature range from A1 to A3. This heat treatment provides a microstructure consisting of a soft ferrite matrix containing martensite inclusions located at the grain boundaries. Tubular products and profiles made of high-strength steels are obtained in continuous units, in which the areas of heating, deformation and cooling are separated. In this case a water-air sprayer must be integrated into the mill line for controlled cooling of the outgoing product. In the case where the deformation process takes place at temperatures below A1, it is rational to carry out the heat treatment directly in the line with heating by means of a through-inductor followed by cooling.
TOPOLOGICALLY ENTANGLED ENERGY AS A MODEL OF ELEMENTARY PARTICLES
Authors: Hryshchenko Alisa
Published: August 2022

Despite the fact that many mathematical models of elementary particles have already been created in theoretical physics, this question still remains open, because a model of an elementary particle that would meet all the requirements and experimental data has not yet been found. We decided to propose another model of elementary particles, which in our opinion is one that correlates well with the results of observations. Our model is that an elementary particle is an energy that takes on a topologically entangled shape. Elementary particles differ not in the energy that makes them up, but in the form in which this energy circulates. If this topological form can unravel under some circumstances, then the particle will not be elementary. If this form is such that it is impossible or very difficult to unravel it under any circumstances, then this particle will look stable as a result of our observation in experiments.
