Published: November 2020

The purpose of this study is to identify factors that influence knowledge management and evaluate its effectiveness in non-governmental organizations in the context of an integrative-oriented approach. The assessment framework for knowledge management effectiveness offered in this study permits the evaluation of decision-making alternatives and their impact on the effectiveness of knowledge management. The analysis of knowledge management effectiveness was performed using a coefficient-based assessment method on practices such as knowledge creation, knowledge acquisition, and knowledge attraction. The assessment framework incorporates both rational and asymmetry-driven styles in the decision-making practice. The study involved six nongovernmental organizations of various specializations from across the globe. The majority of non-governmental organizations showed an upward trend in the knowledge management effectiveness over the past five years. The knowledge creation asymmetry was established. The analysis of knowledge management alternative revealed that five out of six non-governmental organizations should continue those process that were effective at the time of the study and only one organization needs to move to a practice that was less effective during the research period. The major finding is that actions aimed at enhancing the least effective practice will fail to be as effective as the asymmetry-driven decision, even if they ensure a double increment

Published: November 2020

Managerial performance may reflect organizational performance. The achievement of organizational goals closely related to managerial performance, but many researchers only look in terms of workforce performance, whereas managerial roles as leaders of organizations have a huge influence in making decisions. A leader also needs emotional intelligence related to how to make the right decisions according to the organization's goals. This study aims to determine and analyze the effect of emotional intelligence on managerial performance directly and indirectly through decision making. The sample in this study amounted to 44 regional device organizations leaders in Bungo Regency. Data analysis method using path analysis. The results of the study note that emotional intelligence and decision making simultaneously affect managerial performance, but partially decision making has a more dominant influence. The indirect effect of emotional intelligence on managerial performance through decision making is greater than the direct influence of emotional intelligence on managerial performance, thus decision making is able to be an intermediary variable for the influence of emotional intelligence on managerial performance. The implication of the study is that if a managerial has good emotional intelligence it will be able to produce the right decision, so that it will have an impact on managerial performance.

Published: November 2020

The professionalization of university management takes place in many countries and is part of the transformation of the higher education sector. Professionalization of university management in the USA, Great Britain, many EU countries and other parts of the world includes the implementation of the concept of strategic management of public and private universities, as well as strengthening and improving the administration and professional development of managers in the higher education sector. The adoption of Law 2.0 creates an organizational space for the introduction of various management solutions. The basis of organizational changes is the increase in competition, diversity of the university's mission and internationalization. It can be argued that greater freedom in the application of various organizational solutions and increased competition will favor the professionalization of management. Numerous strategic, structural and managerial solutions will be tested at universities and adjusted to their needs.
The error as a defect and as a mean of controlling the activity in work situation
Authors: Leplat Jacques
Published: November 2020

In activity, the error is often evaluated in a negative manner, as the absence of succes. But the error may also have a positive role in that it reveals the characteristics of the activity: so, its knowledge can be a way to control the action, as shown, in particular, the regulatory model for which the action is regulated based on differences in purpose. It is precisely from this model that will be organized this paper. It sugests this can be a framework for analysing the error by showing the work of particular significance. The introduction refers to some general knowledge on the study of error. The second chapter justifies the need to coordinate the study of error to that of activity. The following sections are organized around several themes that mark out the analysis for this coordination: setting goals, assessing the error with the issues of detection and diagnosis, the possible exploitation of the error. A final section addresses the role of the operator characteristics in the production and the management of the error. The conclusion discusses the interest of exploiting the dual character of error for the analysis of activity and on how this exploitation.
Impact de l’allégeance en ses dimensions idéologique et mercenaire sur les réactions aux injustices professionnelles
Authors: Soudan Coralie , Gangloff Bernard
Published: November 2020

Several studies have shown the existence of a norm of allegiance that we can define as the social valorizationof the individuals avoiding to question the social environment, and in particular to question the powers hierarchyin a social system. Thus, it is possible to distinguish the individuals showing allegiance, who are sociallyvalorized, and to oppose them to the rebels, devalorised. Recent studies showed that the norm of allegiance wasnot homogeneous and that it was possible to make a dichotomy according to “ideological” versus “mercenary”reasons conducting to the allegiance or not allegiance, this dichotomy leading to four categories (ideological allegiance,mercenary allegiance, ideological rebellion and mercenary rebellion).In the other hand, facing a person unjustly victim of professional injustice, we can react by adopting “passive”strategies (using for example the victim’s moral or behavioral responsibility: cf. Lerner), but we also canadopt “active” strategies leading to an objective re-establishment of the justice.Our purpose was to study the impact of the allegiance on the passive vs active reactions to professionalinjustices by examining in a differentiated way the ideological versus mercenary reasons of this allegiance ornot allegiance. Our results show that the global as well as the ideological or mercenary allegiance lead to morepassivity. We also observe a gender effect (men and women use different strategies) and a statute effect with adifferenciation between employees and job seekers.

Authors: Brito Janeira Manuel , M. da Silva Carlos , Mendes Lopes António , F. M. da Silva Lucas
Published: November 2020

Adhesives have been used in a wide range of industries, due to their good proprieties when compared with traditional joining methods. Therefore, manufacturers and researchers have been making an effort to study these materials and their characteristics.The main goal of the Advance Joining Processes Unit (AJPU) of FEUP/INEGI is to study and evaluate different types of adhesives under different conditions. One equipment available at the AJPU is a creep testing machine with three independent working stations. As the creep tests must be performed under controlled temperature, the implementation of a thermal chamber was required.This paper describes the design of a thermal chamber for the existing creep testing machine. The chamber needs to be capable of operating between -100 and 200 ºC and have a low temperature gradient. The first step was to design a heat insulator for each upper rod of the creep testing machine, in order to limit the temperature at the load cells to service values.Subsequently, the concept of the chamber was developed. The design decisions with influence on the thermal efficiency of the chamber were supported analytically. The structure, insulation, control and automation projects of the chamber are presented in detail.

Authors: Ermolaev K.A. , Kuz'min M.S.
Published: November 2020

Subject. The article addresses the exports of high-technology products and services.
Objectives. The purpose is to assess the impact of exports of high-technology goods and services on the condition of national economies.
Methods. The study rests on a hierarchy of hypotheses from the general to the specific, i.e. that the increase in exports leads to the economic growth of the country (H1), the exports of goods and services, with varying force, affect the economic growth of the country (H2), the increase in exports of certain categories of high-technology goods directly affects the economic growth of the country (H3). In the first stage, our analysis revealed that under the world economy globalization, exports of almost all countries of the world continue growing. In the second phase, to test the hypotheses we applied methods of multivariate statistical analysis, including the study of a fixed effects model enabling to consider non-measurable individual differences of objects.
Results. The study confirms H1 and H2 hypotheses. While testing the H3 hypothesis, we found that the exports of machinery and equipment, pharmaceutical products, services in the field of computer and telecommunications services affect GDP, and the exports of electronics, insurance and financial services have no statistically significant impact on GDP.
Conclusions. Although the findings require further investigation of identified causal relationships, we can conclude that they may have a significant impact on feasibility and effectiveness of government measures for boosting international trade and introduced trade barriers.
Yerel Yönetimlerde Mali Disiplin ve Mali Kural Uygulamaları
Authors: KARAYAZI Mehtap
Published: November 2020

Klasik iktisadi görüşün ardından ön plana çıkan Keynesyen görüşle birlikte takdiri maliye politikası uygulamaları 1970’li yıllara kadar yaygın şekilde uygulanmıştır. Ekonominin talep yönüyle ilgilenen ve açık yanlısı bir tutum sergileyen takdiri politikalar zaman içinde bütçe açıklarına ve artan borç oranlarına neden olmuştur. 1970’lerden sonra tartışılmaya başlayan kurala bağlı maliye politikaları 1990’lı yıllardan itibaren yaygın olarak uygulanmaya başlamıştır. Günümüzde mali kurallar mali disiplini sağlamak amacıyla çoğu ülkede ulusal düzeyde uygulandığı gibi yerel düzeyde de geniş ölçüde uygulanmaktadır. Özellikle son yıllardaki yerelleşme reformları, yerel yönetimlerin yetki ve sorumluluklarını artırırken mali kaynakların etkin kullanımını daha önemli hale getirmiş ve mali kurallar mali yönetimin bir aracı olarak ön plana çıkmıştır. Bu çalışmada, yerel yönetimlerde uygulanan mali kurallara yönelik yapılan sınırlı çalışmalara katkı sağlaması amacıyla mahalli idare düzeyindeki mali kural uygulamaları teorik olarak incelenmiş, Türkiye’deki ve dünyadaki uygulamalar değerlendirilmiştir. Çalışma sonucunda çoğu ülkede yerel düzeyde uygulanan mali kuralların ulusal kurallar tarafından yönlendirildiği görülmüştür. Türkiye’de resmi olarak bir mali kural uygulaması bulunmamaktadır. Ancak kamu yönetiminde reformların hız kazandığı 2000’li yıllardan sonra yapılan ve kamu kesimini ilgilendiren yasal ve kurumsal düzenlemeler kapsamında yerel yönetimlerde mali kuralların örtük olarak uygulandığı görülmüştür.

The results showed the use of cow manure and Trichoderma sp. able to increase nutrient content and of fragrant lemongrass growth in ex-mining land by giving 432 g cow manure + 43.2 gr Trichoderma sp. / planting hole.
Attribution of value, teaching and assessment in the perception of the performance of specific competencies of undergraduates studying social work
Authors: Carrión Martínez José Juan , Fernández Martinez María del Mar , Luque de la Rosa Antonio , Hernández Garre Carmen María
Published: November 2020

This paper addresses an issue of concern with regards to the teaching of competencies within the context of undergraduate university studies, in this case, in the field of social work. In it, we question if the basic curricular processes of the explicit instructional, teaching and assessment system regarding specific competencies of professional social work are effective in promoting, improving or training in the performance of these specific competencies, or if, on the hand, they are axiological in nature and can better explain the performance of specific competencies by undergraduate students studying social work. A survey method has been followed, analyzing the interaction between these three factors in relation to the self-perception of competency performance. The results suggest that the subjective assessment of the competencies by undergraduate students of social work could affect the relationship between the perception of teaching and evaluation of competencies and the subjective level of their own competency in them. These results provoke an inescapable reflection on the validity of pedagogical practices for promoting the self-assessed performance of the specific competencies of social work by future professional practitioners, opening the door to a reflection on the ways of influencing the competency performance of the current teaching and evaluation processes in higher education.

Published: November 2020

The numerical simulation efficiency of large-scale natural gas pipeline network is usually unsatisfactory. In this paper, Graphics Processing Unit (GPU)-accelerated hydraulic simulations for large-scale natural gas pipeline networks are presented. First, based on the Decoupled Implicit Method for Efficient Network Simulation (DIMENS) method, presented in our previous study, a novel two-level parallel simulation process and the corresponding parallel numerical method for hydraulic simulations of natural gas pipeline networks are proposed. Then, the implementation of the two-level parallel simulation in GPU is introduced in detail. Finally, some numerical experiments are provided to test the performance of the proposed method. The results show that the proposed method has notable speedup. For five large-scale pipe networks, compared with the well-known commercial simulation software SPS, the speedup ratio of the proposed method is up to 57.57 with comparable calculation accuracy. It is more inspiring that the proposed method has strong adaptability to the large pipeline networks, the larger the pipeline network is, the larger speedup ratio of the proposed method is. The speedup ratio of the GPU method approximately linearly depends on the total discrete points of the network.

Published: November 2020

Decreasing the gas pressure is one of the most effective methods to increase the working gas capacity of salt cavern Underground Gas Storages (UGS). In this paper, KING-1 and -2 caverns of Jintan salt cavern UGS, Jiangsu province, China, are studied as an example to investigate their responses under extremely low gas pressure. A 3D geomechanical model of the two caverns is built based on the geological features and rock properties of the host rock salt formation. Different operating conditions are simulated. Safety evaluation criteria for completion casing and caverns are proposed. Thresholds of the indicators consisting of the criteria are given to find the potential minimum gas pressure and the safe working duration of the two caverns. Calculation results indicate that axial strain (along the vertical direction) can perfectly reflect the effects of low gas pressure on the safety of completion casing. The indicators calculated based on the stresses have advantages compared to those based on deformation in assessing the safety of the salt cavern under such low gas pressure and short operating time conditions. The minimum gas pressure gradient of KING-1 and -2 caverns at the casing shoe can decrease from about 7 kPa/m to 5 kPa/m,viz., the minimum gas pressure can decrease from 7 MPa to 5 MPa. The maximum duration for 5 MPa is no more than 118 days. Taking KING-1 cavern as an example, the working gas volume can increase about 17.3%. Research results can provide references for Jintan salt cavern UGS coping with gas shortages.

Esse artigo buscou inferir a importância dos cuidados paliativos no serviço de atenção domiciliar para pacientes com doenças demenciais avançadas. Sob essa perspectiva, faz-se necessário estabelecer o conceito de cuidados paliativos, o qual remete a práticas de assistência promovidas por uma equipe multidisciplinar, com o fito de aprimorar a qualidade de vida do paciente e de seus familiares, perante a uma doença ou agravo que ameace a continuidade da vida. As principais demências avançadas que existem são: Demência vascular, Demência Frontotemporal, Demência por corpos de Lewy e Doença de Alzheimer. O tratamento paliativo produziu um impacto positivo no bem-estar do paciente e melhorou o processo de término da vida, não apenas para a satisfação deste, como também para seus parentes e cuidadores. Ademais, deve-se considerar os impactos de tais serviços no psicológico dos cuidadores, visto que alguns pacientes podem apresentar alterações comportamentais, prejudicando os cuidados. Outrossim, deve-se refletir sobre a problemática da demanda financeira onerosa que se aplicam aos cuidados paliativos em assistência domiciliar, fomentando a recusa do serviço.

Molecular Modelling Reveals Eight Novel Druggable Binding Sites in SARS-CoV-2’s Spike Protein
Authors: Ugur Marion Ilke , Marion Antoine
Published: November 2020

Spike glycoprotein (S), one of the signature proteins of the SARS-CoV-2, initiates the membrane fusion and virus entry to the host cell. The S protein’s key role in virus viability makes it an attractive candidate for drug design studies. Besides the recent structural characterization of the S protein, information fundamental to drug design such as possible binding sites or molecular fragments with high affinity towards the protein is unknown. We explored the druggability of this protein, focusing on its S1 and S2 domains. We performed virtual screening studies on both closed and open forms of the protein, using both cryo-EM structures and geometries obtained from molecular dynamic simulations. We targeted 20 distinct ligand binding centres with a set of about 9,000 molecules. Our docking calculations followed by molecular mechanics-based refinement of ligand/protein complexes led us to detect eight binding sites that were so far undocumented. By further focusing on a subset of approximately 1,000 approved and marketed drugs, we aimed at suggesting a new direction for drug repurposing strategies that were not considered so far. Within this approved set, our best hits include a number of antibacterial and antiviral drugs (e.g., Streptomycin, Nelfinavir), which were not yet investigated clinically in treating COVID-19. We also identified some molecules (e.g., folic acid, Famotidine) that were already suggested to be effective towards SARS-CoV-2, yet without molecular explanation. Our results also indicate a great affinity of SARS-CoV-2’s S protein towards nucleoside analogues, either approved or experimental.

Published: November 2020

The selective conversion of methane to methanol remains one of the holy grails of chemistry, where Cu-exchanged zeolites have been shown to selectively convert methane to methanol under stepwise conditions. Over the years, several active sites have been proposed, ranging from mono-, di- to trimeric Cu(II). Herein, we report the formation of well-dispersed monomeric Cu(II) species supported on alumina using surface organometallic chemistry and their reactivity towards the selective and stepwise conversion of methane to methanol. Extensive studies using various transition alumina supports combined with spectroscopic characterization, in particular electron paramagnetic resonance (EPR), show that the active sites are associated with specific facets, which are typically found in gamma- and eta-alumina phase, and that their EPR signature can be attributed to species having a tri-coordinated [(Al2O)CuIIO(OH)]-,T-shape geometry. Overall, the selective conversion of methane to methanol, a two-electron process, involve two of these isolated monomeric Cu(II) sites that play in concert.
Water Oxidation Kinetics of Nanoporous BiVO4 Photoanodes Functionalised with Nickel/iron Oxyhydroxide Electrocatalysts
Authors: Francàs Laia , Selim Shababa , Corby Sacha , Lee Dongho , Mesa Camilo , Pastor Ernest , Choi Kyoung-Shin , Durrant James R
Published: November 2020

In this work, spectroelectrochemical techniques are employed to analyse the catalytic water oxidation performance of a series of three nickel/iron oxyhydroxide electrocatalysts deposited on FTO and BiVO4, at neutral pH. Similar electrochemical water oxidation performance is observed for each of the FeOOH, Ni(Fe)OOH and FeOOHNiOOH electrocatalysts studied, which is found to result from a balance between degree of charge accumulation and rate of water oxidation. Once added onto BiVO4 photoanodes, a large enhancement in the water oxidation photoelectrochemical performance is observed in comparison to the un-modified BiVO4. To understand the origin of this enhancement, the films were evaluated through time-resolved optical spectroscopic techniques, allowing comparisons between electrochemical and photoelectrochemical water oxidation. For all three catalysts, fast hole transfer from BiVO4 to the catalyst is observed in the transient absorption data. Using operando photoinduced absorption measurements, we find that water oxidation is driven by oxidised states within the catalyst layer, following hole transfer from BiVO4. This charge transfer is correlated with a suppression of recombination losses which result in remarkably enhanced water oxidation performance relative to un-modified BiVO4. Moreover, despite similar electrocatalytic performance of all three electrocatalysts, we show that variations in water oxidation performance observed among the BiVO4/MOOH photoanodes stem from differences in photoelectrochemical and electrochemical charge accumulation in the catalyst layers. Under illumination, the amount of accumulated charge in the catalyst is driven by the injection of photogenerated holes from BiVO4, which is further affected by the recombination loss at the BiVO4/MOOH interface, and thus leads to deviations from their behaviour as standalone electrocatalysts.
Reescrituras del género del terror desde las nuevas realidades digitales en Cam de Daniel Goldhaber
Authors: Bedoya Forno Rodrigo
Published: November 2020

Este artículo busca explicar cómo la película Cam utiliza ciertos tópicos del género de terror (en particular, la figura del doppelgänger, o doble) para, a partir de ellos, observar el cambio de las nuevas tecnologías digitales en la dinámica de nuestra cotidianidad. La película plantea una mirada sobre cómo las tecnologías digitales se han convertido en nuestras herramientas de trabajo y abastecimiento, a través de la historia de una camgirl cuya identidad es usurpada por una entidad, creando una dinámica de vida en la que no hay que desplazarse y todo se puede hacer en base a un clic. La cinta también le toma el pulso a las nuevas formas del cine de terror, estableciendo el internet como un espacio donde la violencia y el sexo se han convertido en herramientas para generar mayor interactividad entre los usuarios, y permitir mayores ganancias. Pero no solo eso: Cam utiliza una serie de miedos contemporáneos ligados a las posibilidades de las nuevas tecnologías (el verse bloqueado de una cuenta, la posibilidad de ser hackeado) para establecer un universo en el cual todas las explicaciones son posibles, y en las que resulta muy difícil establecer qué cosa es el enemigo a vencer.
Espectropolítica: imagen y hauntología en la cultura visual contemporánea
Authors: Gómez Gabriel Núria
Published: November 2020

En su libro Espectros de Marx, Jacques Derrida propone el término hauntología (hantologie) como un giro epistémico dedicado a pensar las formas en las que la tecnología materializa la memoria que parte de la premisa de que nada goza de una existencia puramente positiva y de que, como nos recuerda el crítico musical Mark Fisher en sus reflexiones sobre la depresión, todo lo que existe es posible únicamente sobre la base de una serie de ausencias que lo preceden, lo rodean y le permiten poseer consistencia e inteligibilidad. Este artículo presenta el tropo espectropolíticas con el fin de observar cómo ciertos eventos propios del capitalismo tardío y las abstracciones financieras reverberan en la psiquis colectiva y se transforman en apariciones espectrales. Lejos de una comprensión del fantasma oscurantista como algo real, entendemos su presencia como un signo o una metáfora de la visión que actúa como una figura clarificadora con un potencial específicamente ético y político. Asimismo, las nuevas materialidades de la visualidad fugaz, fugitiva y subjetiva de nuestro presente (dominado por Internet y los procesos de privatización psíquica), nos interrogan acerca de las colectividades que se organizan en los modos de ver de las sociedades contemporáneas y en las huellas de las estructuras de poder que subyacen en ellas.
Archivos fílmicos en línea: apuntes en torno al acervo universitario chileno
Authors: Albornoz Fariña Ignacio
Published: November 2020

El presente artículo busca generar una primera y tímida reflexión en torno a la reciente constitución de archivos cinematográficos en línea en Chile, otorgando una atención particular a las iniciativas ―ligadas a la promoción y difusión de sus acervos históricos particulares― nacidas en el seno de las tres principales universidades del país: la Universidad de Chile, la Universidad Católica y la Universidad Técnica del Estado (actual USACH). Estas iniciativas serán inscritas en el marco más global de una “deslocalización de los contenidos” y de una “pixelización de las colecciones”, consecuencias del viraje fundamental de las prácticas archivísticas acarreado por la irrupción de la tecnología digital. A medio camino entre el estudio de caso y la meditación teórica, este artículo intentará pues glosar y confrontar las arquitecturas y dispositivos de las distintas plataformas de consulta que estas tres instituciones han puesto a disposición de sus usuarios.

Coronavirus disease 2019 (COVID-19) has recently emerged in China and caused a global pandemic. WHO announced that COVID-19 could be characterised as a pandemic due to unprecedented swift global spread and severity of the outbreak. When infected with the virus, patients usually have a fever, dry cough, dyspnoea, myalgia, headache and sometimes diarrhoea. Updates on molecular characteristics  of SARS-CoV-2, treatment and epidemiological control are more important  to help optimise the disease control measures Thrombotic complication is an essential issue in patients infected with COVID-19. Concomitant venous thromboembolism (VTE) seems to be a potential cause of unexplained deaths in COVID-19 cases. Thrombocytopenia, elevated D-dimer, prolonged prothrombin time, and disseminated intravascular coagulation are the clinical findings related to such condition. In China, anticoagulant therapy in severe COVID‐19 was suggested for improving outcome. Studies showed the urgency for  VTE diagnostic strategies. Aetiology may be multifactorial, and therefore, we  review the available literature relevant to acute venous thromboembolism associated with novel coronavirus infection.
Autonomous English Language Learning Beyond the Classroom: Indonesian Tertiary Students’ Practices and Constraints
Authors: Daflizar Daflizar
Published: November 2020

. In response to the interest in learner autonomy in recent years, educational research has been increasingly paying attention to students’ out-of-class autonomous learning activities. This study aims to (1) describe the extent to which Indonesian tertiary students engaged in autonomous English language learning outside the class, (2) explore their perceived constraints in practicing autonomous learning, and (3) examine whether there are any significant differences in the autonomous learning activities between female and male students and between the English major students and non-English major students. Employing the explanatory mixed-method design, a total of 402 first-year students completed a questionnaire, and 30 of whom were interviewed. The questionnaire data were analyzed using descriptive statistics and non-parametric tests, and the interview data were analyzed using thematic analysis. The results showed that the students did engage in several out-of-class English learning activities, however many of the activities were more receptive than productive. The interviews echoed the questionnaire results, and the students claimed that they were not autonomous in their learning due to several constraints. The results also revealed that there is no significant difference in the level of practice of autonomous out-of-class activities based on gender but a significant difference was found concerning majors of study. Practical implications for the Indonesian context are put forward.

El derrame pericárdico puede desarrollarse a partir de cualquier enfermedad pericárdica, incluida la pericarditis y varios trastornos sistémicos, como neoplasias malignas, tuberculosis pulmonar, insuficiencia renal crónica, enfermedades de la tiroides y enfermedades autoinmunes. Las causas de un gran derrame pericárdico que requiere pericardiocentesis invasiva pueden variar de acuerdo a las condiciones sanitarias. La ecocardiografía transtorácica es la herramienta más importante para el diagnóstico, la clasificación, el procedimiento de pericardiocentesis y el seguimiento del derrame pericárdico. El taponamiento cardíaco es una especie de shock cardiogénico que generalmente se considera una emergencia médica. Los médicos deben comprender la fisiología del taponamiento, especialmente porque puede desarrollarse sin un gran derrame pericárdico. Además, los médicos deben correlacionar los hallazgos ecocardiográficos de taponamiento, como el colapso del ventrículo derecho, colapso auricular derecho y variación respiratoria del flujo mitral y tricúspide, con signos de taponamiento clínico, como hipotensión o pulso paradójico. La pericardiocentesis percutánea ha sido el procedimiento más útil en muchos casos de derrame pericárdico grande, taponamiento cardíaco o derrame pericárdico de etiología desconocida. El procedimiento debe realizarse con la guía de una ecocardiografía.

Este artigo discute a produção de vídeos amadores de experimentos por licenciandos em química. O objetivo da pesquisa foi investigar os vídeos em termos técnicos-estéticos, procedimentais e conceituais da química, bem como o ponto de vista dos produtores no intuito de potencializar esta como ferramenta para o processo de ensino. Os vídeos foram compostos por diversos elementos culturais e estéticos que podem ser considerados importantes em materiais audiovisuais, bem como para um processo educativo que favoreça o engajamento e fomente a liberdade, a criatividade e a diversão. Foram observadas algumas dificuldades na explicação conceitual dos experimentos e ausência de recomendações sobre segurança e o descarte de resíduos. Dessa maneira, a discussão dos vídeos entre professor e estudantes pode potencializar o processo formativo.

Изложены общие представления о механизмах, управляющих частотой и интенсивностью полосы рассеяния на колебаниях протона в O—H⋯O водородной связи в процессе ее эволюции от слабой до предельно сильной. КР-спектры кристаллов глицин фосфата и протонированного диметилформамида, обладающие сильной и предельно сильной водородной связью, получены в интервале температур 5—300 K. Показано, что сильная связь реализуется только при определенном химическом состоянии донора и акцептора и что для регистрации колебаний протона требуются низкие температуры или высокие давления. Представлена схематическая зависимость частоты колебаний протона от жесткости водородной O—H⋯O связи.

Two novel compounds [Zn(bitmb)(L)]·2H2O and [Co(bitmb)(L)]·2H2O are prepared under hydrothermal conditions (bitmb = 1,3-bis(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene; H2L = 1,3-bis-(4-carboxy-phenoxy)propane) and characterized by the single crystal X-ray diffraction analysis. Both complexes are isostructural and contain 3-fold right-handed helical 1D chains. IR and PXRD spectra, TG curves, and photoluminescent properties are also studied.

A new thiosemicarbazone derivative ligand N-(4-chlorophenyl)-2-(pyridin-2-ylmethylene)hydra­zine-1-carbothioamide (HL) and its zinc(II) complex [ZnL2]·CH2Cl2 (1) are prepared and cha­racterized by elemental analysis, FTIR and 1H NMR spectroscopy, and single crystal X-ray diffraction (for 1). The X-ray analysis reveals that the zinc atom is octahedrally coordinated by two NpyNimineSthiolate-donor ligands with the mer form. The HL ligand is deprotonated during the complexation process through the thiol group. In the crystal network of 1, the N—H⋯S hydrogen bonds form R22(8) hydrogen bond motifs. In addition, the crystal network is more stabilized by π—π stacking and C—H⋯π interactions. The ability of complex 1 to interact with ten selected biomacromolecules (BRAF kinase, CatB, DNA gyrase, HDAC7, rHA, RNR, TrxR, TS, Top II, and B-DNA) is investigated by docking studies. The results show that in many cases, complex 1 can interact with proteins better than doxorubicin.

Аморфно-кристаллический сплав квазибинарной системы TiNi—TiCu с содержанием меди 25 ат.% изготовлен методом быстрой закалки из жидкого состояния в виде тонких лент. Полностью аморфное состояние получали с помощью электрохимической полировки. Показано, что кристаллическая структура, полученная методом высокоскоростной электроимпульсной термообработки, значительно отличается от таковой, полученной методом изотермической термообработки. Кристаллизация исходной ленты сопровождается формированием столбчатых кристаллов от обеих поверхностей ленты и крупных кристаллов линзовидной формы в объеме ленты, при этом структура столбчатых кристаллов повторяет морфологию и текстурированность исходного кристаллического слоя. Уменьшение времени электроимпульсного воздействия до 1 мс приводит к росту доли столбчатых кристаллов, увеличению их высоты и уменьшению ширины. После кристаллизации аморфной ленты структура столбчатых кристаллов от обеих поверхностей имеет одинаковую кристаллографическую ориентацию.

Three months after a coronavirus disease (COVID-19) outbreak in Kupferzell, Germany, a population-based study (n = 2,203) found no RT-PCR-positives. IgG-ELISA seropositivity with positive virus neutralisation tests was 7.7% (95% confidence interval (CI): 6.5–9.1) and 4.3% with negative neutralisation tests. We estimate 12.0% (95% CI: 10.4–14.0%) infected adults (24.5% asymptomatic), six times more than notified. Full hotspot containment confirms the effectiveness of prompt protection measures. However, 88% naïve adults are still at high COVID-19 risk.
