Authors: Mehrabi Afshin , Sharifi Hassan , Asadi Asadabad Mohsen , Amini Najafabadi Reza , Rajaee Ali
Published: August 2020

AISI 4340 is one of the most widely used steels in high-risk industries such as military, nuclear and aerospace. The strength of this steel is capable of increasing to 1 825 MPa with quench and temper heat treatment, but it results in low toughness, low impact properties and brittle-fracture especially at low temperatures. In this study, the intermediate quenching treatment was used to induce ferritic–martensitic dual-phase (∼50/50 ferrite/martensite) microstructure that led to an impact energy of 93.6 kJ m−2, which was 241% higher than that of quench and temper treatment. Moreover, mechanical tests revealed tensile strength and hardness of 911.5 MPa and 43 HRC, respectively. Also, fractographic analysis confirmed the occurrence of the desirable ductile fracture mechanism.

PHENOMENON OF THE BIEDERMEIER PIANO MUSIC IN XIX CENTURY
Authors: Nataliia Chuprina
Published: August 2020

The aim of the article – to consider the Biedermeier as a phenomenon of European culture, generated by the Restoration era. The evolutionary and typological qualities of Biedermeier in all the diversity of its national models (German, Polish, Russian, Italian, French) are projected on the piano music of XIX century and its performing traditions; to present Biedermeier as a specific direction of musical art which creates the conditions for understanding and absorbing of a complex academic repertoire by an unprepared audience. Methodology of the article – historical, general philosophical, social analysis of the Biedermeier as a cultural phenomenon, comparative analysis of national characteristics of the Biedermeier display.Scientific novelty – the Biedermeier phenomenon is presented as a specific direction of musical art which creates the conditions for understanding and absorbing of a complex academic repertoire by an unprepared audience. Biedermeier traits characteristic of different national and religious traditions are also analyzed and presented.Conclusions: the Biedermeier as a specific phenomenon of musical culture, a kind of connecting musical “link” between elite art and “mass consumer” of art, creates certain pedagogical prerequisites for raising interest in various social strata of the society for the complex repertoire of classical music. Such an approach in understanding the idea of the Biedermeier, including the musical one, will prove to be essential in the revival of the values of planetary human unity and state principles – by the forces of individual and personal efforts of citizens and creators of Ukraine and countries and nations territorially historically close to it, since technological and analytical achievements and spiritual and social transformations in the human society are derived from the indicated general idea of the Great – through the small.

The aim of the study is the examination of the nephron tubules morphological changes at the early and late stages of the experimental chronic opioid effect. Varying degrees of the morphological changes of proximal convoluted tubules, loops of Henle and distal convoluted tubules under chronic nalbuphine effect in the dynamics have been detected. The materials of the study – kidneys of 56 sexually mature male-rats. The experimental animals received daily intramuscular nalbuphine injections for 98 days. From the first to the fourteenth day of the experiment the dose of nalbuphine was 0,212 mg/kg. Every next two weeks nalbuphine injections were done in increasing doses. For histological investigation was used commonly agreed method. The colouring was performed using hematoxylin and eosin as well as azan by Heidenhain's method. Varying degrees of morphological changes of proximal convoluted tubules, loops of Henle and distal convoluted tubules under continuous nalbuphine injection in the dynamics have been detected. The most vivid alterative changes can be observed in proximal convoluted tubules both: at the early and late stages of the experiment. At the early stages as of the 14th day of the experiment signs of granular dystrophy appear, as of the 28th day – necrotic changes, progressing further at the late stages of the experiment. The loops of Henle undergo sporadic destructive changes at the early stages and at the beginning of the late stage of the experiment. Distal convoluted tubules have been necrotic altered only at the late stages of the experiment.

The paper considers the influence of the vibrational load on the deformation of soils with an increased moisture content. In the course of theoretical studies, it was established that the effect of vibration on soil deformation is observed when vibrational accelerations of a strictly defined limiting value are reached, which is usually called critical. It is established that the dependence of the critical acceleration on the specific static pressure is parabolic. In this case, the influence of vibration on the deformation of the soil is well described by the hyperbola equation. The presence of a limit of the sensitivity of the soil to vibrations is established, at the attainment of which a complete destruction of the cohesion forces is observed, which are not restored, and the internal friction reaches a maximum determined by the physical and mechanical characteristics of the soil. It is determined that the vibrations caused by the force in the vertical plane do not have a noticeable effect on the shear resistance. If the vector of the perturbing force coincides with the plane of shear, then the tangential stresses form an exponential dependence.

Authors: Vasyl Grebin
Published: August 2020

This article presents the results of forecasting of future changes in water runoff in the basin of the Dnister River. The forecast is made until the year 2100 in 30-year periods. For forecasting, the data from the network of hydrological stations at Dnister and its affluents. After conducting the verification (testing) of the selected REMO climatic model, an adjustment coefficient was developed and its use was proposed when forecasting the runoff. The results of the forecast have shown the decrease in the value of the runoff modulus for each of the forecasted periods. The deviation of forecasted runoff rates from the control period (1970-2000) with the use of the coefficient for the period 2011-2040 was (in average for the basin) 0.81 l/s*km2 (9%); for the period 2041-2070 it was 0.96 l/s*km2 (11%); for the period 2071-2100 it was 0.88 l/s*km2 (10%).

The purpose of the study was evaluating the peculiarity of bone mineral density (BMD) and body composition in patients with spinal cord injury (SCI). 51 men with SCI were enrolled to the study. The comparison group consists of 51 healthy men which were standardized by age and body weight. The study revealed in patients with SCI significantly higher rate of osteoporosis (84.31%) and sarcopenia (43.14%) in comparison with healthy men (1.96% and 25.49% accordingly). In healthy men the correlation analysis revealed the wide-ranging influence of body composition on lower extremities BMD. Thus, femur neck BMD is determined by the lean mass of upper extremities (r = 0.33, p <0.05), lower extremities (r = 0.38, p <0.05), trunk (r = 0.41, p <0.05) and total body (r = 0.43, p <0.05). Hip BMD depends on the lean mass of trunk (r = 0.36, p <0.05) and total body (r = 0.34, p <0.05). Lower extremities BMD correlates with lean mass of trunk (r = 0.33, p <0.05) and lower extremities (r = 0.32, p <0.05). In men with SCI it was found the correlation between femur neck BMD and trunk lean mass (r=0.30, p<0.05); hip BMD correlates with lean mass of trunk (r=0.31, p<0.05) and lower extremities (r=0.35, p<0.05); lower extremities BMD correlates with lean mass of trunk (r = 0.41, p <0.05) and lower extremities (r = 0.32, p <0.05). Consequently, our study showed the influence of lean body mass on lower extremities BMD in both groups, which should be taken into account during managements of patients with SCI.

Published: August 2020

The study was aimed to analyze theoretical material on the issues of idiomatic expressions and their translation, as well as to define and assess the importance of the translation of idiomatic expressions, which students can encounter in technical literature, into Ukrainian. The transformation of image of English idioms is a very difficult task because of their semantic richness, imagery, brevity and the brightness. On the one hand, English idioms are widely used in oral speech, artistic and political literature. On the other hand, English idioms are used in technical literature, though not so often. The choice of one or another type of translation depends on the features of idiomatic expressions that students must recognize and be able to transform their meaning, brightness and clarity.

Published: August 2020

The need for repositioning the funding of adult and non-formal education (ANFE) in Anambra State cannot be overlooked as manpower and material resources needed for such programs can be acquired when there is adequate funding. The study focused on the repositioning the funding of ANFE in Anambra State. Descriptive survey research design was adopted in this study, guided by three research questions. The population of the study comprised 331 instructors in all the government-owned adult education centres in Anambra State. There was no sampling because the population was manageable. Questionnaire was the instrument for data collection which was validated by two experts in the Department of Adult and Continuing Education, Nnamdi Azikiwe University, Awka. Cronbach Alpha was used to determine the internal consistency of the instrument and the overall reliability coefficient of 0.79 was obtained. Mean statistics was used to answer the research questions. The findings indicated that ANFE is funded to a low extent in Anambra State. The study also revealed that some of the challenges confronting ANFE in Anambra State include: difficulties in identifying budget meant for ANFE, lack of information on funding by individuals, inadequate funding by the government, among others. The study further showed that the strategies to be adopted in repositioning the funding of ANFE in Anambra State are: distinct budget allocation by federal and state government for ANFE, effective utilization of fund accruing to ANFE, assisting of ANFE through regular funding by international bodies and NGOs, among others. Conclusion was drawn and the study recommended that governments both federal and state should provide adequate support to ANFE, especially through proper funding and adequate monitoring of such funds.

The diversity of learners within education is neither linear nor constant. Educators are challenged to be responsive and understanding when encouraging learners to construct meaning while adhering to stringent standards. The objective of this study is to integrate science standards into authentic learning experiences, created in both a traditional teaching method and virtual reality (VR) platform, for 8th grade middle school students in Lafayette, Louisiana. The authentic experiences were based on oral histories of the residents of Isle de Jean Charles, Louisiana, who have lost 98% of their ancestral homeland since 1955. These experiences were then tied to the National Science Standards (8-MS-ESS1-4, 8-MS-ESS2-2, and 8-MS-ESS3-1). The students were split into two groups and given either a PowerPoint or VR experience, both having the same content. The researchers tracked engagement, focus, interest, and how important the students thought the content was. Using an experimental approach, the researchers also gave a pre- and posttest to determine if the VR experience resulted in better academic learning than a regular, PowerPoint-based lecture. The students were also asked to comment on their experience of the PowerPoint versus the VR and describe what their experience.

Inflammatory processes cause changes in the permeability of the blood brain barrier. Non-steroidal anti-inflammatory drugs (NSAID) are most commonly used to treat these inflammatory processes, including meloxicam, and they can reach the central nervous system (CNS) and cause neurotoxicity. Since there are no studies evaluating the neurotoxicity of NSAID in alternative models of toxicity, the aim of this study was to evaluate the acute neurotoxicity (through nematodes changes in behavior) of meloxicam in an alternative in vivo model, Caenorhabditis elegans, as well as, to determine meloxicam toxicity through LD50 and development assessments. Meloxicam LD50 was high (50.03 mg/mL) and only the highest dose (100 mg/mL) caused a decrease in the nematode body size, indicating low toxicity in this alternative model. Besides, a neurological effect was observed only in the highest dose. Meloxicam showed neurotoxicity only at a very high dose, suggesting low potential to cause toxicity in the CNS. However, further studies are necessary to evaluate meloxicam neurotoxicity.

Published: August 2020

The new pneumonia caused by coronavirus 2 of severe acute respiratory syndrome (COVID-19) has the potential to develop biopsychosocial instability in the population and is responsible for much of the increase in mental disorders that occur after the beginning of the pandemic, especially among health professionals working on the front line. Physical exhaustion and mental distress leads them to search alternative therapies for harm reduction, such as therapeutic communication therapies, active listening, meditation, mindfulness and yoga. Such actions can decrease stress and have potential harm reduction in relation to the development of posttraumatic stress disorder. In addition, religiosity and/or spirituality reduced the psychological suffering of health workers, not only in moments of pandemic, but in the daily work routines.
University Solidarity Management

Published: August 2020

In the perspective of discussing a university management proposal that places an alternative epistemological conception and understands the multidimensionality of human beings and social systems (as a critique of economic instrumentality) and the multidimensionality of the educational phenomenon, this article presents a theoretical synthesis, an essay of idea, in the sense of proposing a model of solidarity management, in the perspective of its dimensions (Cosmopolitan Rationality; Multidimensional Model of Administration Management; Intercultural Translation). The solidary management of the university centralizes the debate on interculturalityfrom the perspective of emancipation, while activating the reflective process on how to strategically operationalize actions that are guided by an integrative rationality and coordinate the dimensions of the educational phenomenon, in this case: culture, politics, pedagogy and economics. It is in the scope of a democratization of knowledge that this management advances from the “societal” management, as it comprehends a perspective on participation that qualifies the knowledge and practices of social agents in building proposals as credible, and the social organization should focus its efforts and trigger the experiences of the subjects so that the intercultural translation process incorporates comprehensive and purposeful practices within symbolic interactions.

Published: August 2020

Innovation can be understood as a technological asset in relation to the protection of knowledge with regard to intellectual property, and a challenge for universities and companies regarding the transfer of technology, since there are numerous variables that influence even full monetization. It is important to reflect on all the energy expended in relation to the authors involved in this process, having as general objective to analyze the perception of researchers about the processes of protection of intellectual property and its security mechanisms, characteristics of innovation and technology transfer. A structured research was used as a methodology, using the survey method, applied to specialists, with hypotheses formulated, based on the literature review. The results mainly understand that there is a moderate correlation index in quantitative terms of graduate programs and number of patents, by region of Brazil, an awareness in agreement with the elements of protection of intellectual property. In global efforts among researchers, universities and companies, only about 5% of patents have reached the level of royalty generation, demonstrating that the other 95% are still available for potential exploitation for society.

Published: August 2020

Climatic changes and high temperatures have been affecting animal production and the well-being of laying birds, with heat stress and high mortality rates, generating economic losses. Legacy databases can contain information to help model thermal comfort at climatic extremes. They can enable decision trees to be created through the use of data mining to prevent mortality and production losses. Thus, the objective of this study is to seek to develop decision trees, for application as an alert system, for the incidence of caloric stress in the production of layers. We used a database of three aviaries located in the city of Bastos-SP, collected in 2013. The data were organized in Excel® spreadsheets, and processed with the Weka® software with the J48 (C4.5) algorithm for mining of the data. The technique allowed the construction of decision trees that in the chosen sheds were classified with respectively 99.73%, 99.61%, and 98.71% of correct answers and with Kappa indexes equal to 0.9958, 0.9907 and 0.9663, which indicate that the three classifiers built are excellent. Thus, the proposed system, with the decision trees built, can serve as a basis for the construction of an alert system to be applied to the three warehouses simultaneously.

Published: August 2020

Simaba cedron, popularly known as "cedron", is largely used for fever and snake bites. Its seeds are used in the treatment of stomach problems and liver infections. The fruits are used for the treatment of pain and malaria while its bark is an antispasmodic. Simaba cedron is generally propagated through seeds, but with limited success, as the low viability of same restricts its propagation. In view of such difficulty, it becomes necessary the study for adequate conditions for the large scale production of these seedlings. Being it known that in several species, the use of micropropagation has made it possible to obtain a large amount of disease-free and more homogeneous seedlings, in reduced time and physical space, in comparison with conventional propagation methods, the objective of this work was to analyze the effect of two culture media on the production of aseptic parent plants as a first step in the development of a micropropagation protocol for Simaba cedron. The seeds were collected from a matrix plant located in the Amazon Biotechnology Center (CBA), in Manaus/AM. The experiment was installed at the Vegetable Tissue Culture Laboratory, where the  explants were desinfected and grown in culture medium  according to Murashige & Skoog (MS) and in Wood Plant Medium (WPM), during 60 days. The disinfestation rate obtained was 75% and, of the disinfested seeds, 100% germinated. The cultivation medium that was more favorable to the cultivation of simaba was the MS, where the multiplication rate was of 8.0: 1, whose seedlings reached, in average, 4.8 cm and 75% of rooting.
The Influence of Globalization on National Education Policies in Nigeria
Authors: Ibe Patrick Ik. , EKOH-NWEKE ANGELA CHEKWUBE , AGU AUGUSTINE OBELEAGU
Published: August 2020

Globalization is one of the most widely contested phenomena by scholars because of its complexity, elusive nature and attribution for its positive and negative outcomes. Historically, globalization and education are very interrelated. This paper will look at the influence of globalization on National Education Policies in Nigeria. The process of globalization began as early as the fourteenth century or at least with emergence of capitalism in the sixteenth century which resulted in the creation in Europe and USA of national education systems. This process continued and resulted in the transfer of these national education systems by colonial powers on other nations, and eventually to the establishment of the globalization institutions and instruments (WB, IMF, UNESCO, UNICEF). The paper will argue that Nigeria since the introduction of national system of education under colonialism, has always been a recipient of her education policies. The country has not been able to articulate/formulate an endogenous education policy. All opportunities (military to civilian, civilian to military) had always ended in the reproduction (expanding or contracting) of the existing policy. Nigerian education policy makers should try to domesticate globalization and related processes by purposefully interacting with globalization demands as policies are being formulated and implemented.

Published: August 2020

Background: Black soybean seed coat contains an abundance of flavan-3-ols and possesses various bioregulatory functions. Nitric oxide (NO) is produced by endothelial nitric oxide synthase (eNOS) in vascular endothelial cells and regulates vascular function through vasodilation and the inhibition of platelet aggregation in blood vessels. It has been reported that flavan-3-ols increase NO production, but many previous reports used a high concentration of flavan-3-ols. In the present study, we investigated the effect of flavan-3-ol-rich black soybean seed coat extract (BE) on NO production at a lower concentration that is close to the concentration after permeation through the monolayer of Caco-2 cells.Methods: Human umbilical vein endothelial cells (HUVEC) were incubated with BE, and then NO production in the medium and eNOS phosphorylation in the cells were examined. Intestinal epithelial Caco-2 cells on the upper side of a transwell filter were co-cultured with HUVEC on the basolateral compartment of the transwell apparatus. BE was added from the upper side, and the basolateral medium was collected to measure the concentration of NO and the content of flavan-3-ols. Furthermore, HUVEC were incubated with each flavan-3-ol in order to individuate the most effective compound in BE.Results: BE significantly increased NO production in the medium of HUVEC. When polyphenols in BE were removed from the basolateral medium by ethyl acetate extraction, increased NO production from HUVEC was not observed. Additionally, BE increased phosphorylation of eNOS and Akt in HUVEC. A portion of flavan-3-ols in BE had permeated through intestinal epithelial cells. Among the flavan-3-ols that had permeated, procyanidin C1 had the strongest effect on NO production in HUVEC at the concentration that had permeated the monolayer of Caco-2 cells. Procyanidin C1 (0.05 µM) also induced phosphorylation of eNOS and Akt in HUVEC without affecting the cAMP level. Conclusion: A portion of flavan-3-ols in BE directly promoted NO production through the Akt/eNOS pathway in vascular endothelial cells. These findings suggest that flavan-3-ols in the black soybean seed coat may contribute to improve the vascular function.Keywords: Black soybean seed coat polyphenols; NO; eNOS; Akt; vascular endothelial cells

Introdução: Os cuidados paliativos para pacientes oncológicos tem por finalidade promover a qualidade de vida por meio do controle de sinais e sintomas, melhoria do bem-estar físico, emocional, social e espiritual. Objetivo: Avaliar a qualidade de vida de pacientes oncológicos em cuidados paliativos. Método: Trata-se de uma pesquisa descritiva, transversal, de abordagem quantitativa, realizada com 21 pacientes internados em uma unidade de cuidados paliativos. Foram coletados dados sobre aspectos sociodemográficos e clínicos, e utilizada a escala do European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire Core15 PAL (EORTC QLQ C-15 PAL) para avaliação da qualidade de vida. Resultados: A media de saúde global foi de 60,32, sendo a qualidade de vida considerada satisfatória. Na escala de sintomas, os domínios mais afetados foram dor (52,38), constipação (46,03) e fadiga (42,86). A função emocional (37,30) mostrou-se pior do que a avaliação da função física (59,79). Houve relação significativa do tempo de diagnostico com a qualidade de vida geral e a dispneia do performance status de Karnofsky (KPS) com o funcionamento físico, bem como da presença de metástase com dispneia. Conclusão: A qualidade de vida deve ser avaliada diariamente, visto que os cuidados paliativos consideram, além dos sintomas, o conforto do próprio paciente durante o estado de doença que ameaça a vida e as intervenções efetivas de cuidados, permitindo assim o direcionamento da atuação da equipe multiprofissional.

Mixing is essential to increase the efficiency of interactions between active microbes and organic matter during the anaerobic digestion process. The purpose of this research is to study the effect of mixing rate on the stability of one stage anaerobic digesters in biogas production in terms of pH and alkalinity. The production of biogas from palm oil mill effluent was carried out in a 6000 ml batch reactor at varying mixing rates: 100 rpm, 150 rpm, 200 rpm, 250 rpm, and 300 rpm. The reactor is operated with a mixture condition maintained at a pH of 7 ± 0.2 and an operating temperature of 55 ° C. NaHCO3 is added to the mixture to control and maintain the pH of the mixture. Analysis of pH and alkalinity is carried out every day to see the reactor stability. The best results were obtained at a mixing rate of 200 rpm with the pH produced stable during the process is 7. The alkalinity profile produced at each mixing rate was relatively stable with an alkalinity range is 3500-4500 mg/L. The best mixing rate is 200 rpm with a stable pH and alkalinity and the highest biogas production is 457 ml/day.

The process of producing, refining and transporting petroleum can cause pollutants that are harmful to the environment and the living things that surround them. Indigenous microorganisms can be a solution to degrade hydrocarbons that are difficult to degrade. This study aims to isolate the indigenous bacteria from pollutant-contaminated soil and test its effectiveness in degrading hydrocarbons. The research began with soil sampling at the Joint Operating Agency of PT Siak Bumi Pusako-Pertamina Hulu Siak Regency, Riau Province with a purposive sampling method. The next step is the isolation of indigenous bacteria, testing the parameters of pH, Optical density (OD) and CO2 levels during the 16 incubation periods and determining the highest percentage of biodegradation. The results showed that Pseudomonas sp. with a code BTM2 (Bakteri Tanah Minyak 2) had the largest percentage (52.20%) after 16 days of incubation under optimum conditions to degrade the total hydrocarbon of petroleum. Pseudomonas sp. BTM2 is the most effective isolate to degrade hydrocarbons.
Islamic Finance and its Contribution to Solving the Current Financial Crisis
Authors: Bashir Mohamed Sharif
Published: August 2020

As a result of the global financial crisis and its effects on the world economy, there is an increasing awareness and exploration of more vigorous frameworks and types of financial tools and intermediations. With its emphasis on asset-backed transactions, Islamic finance can contribute to overcoming the challenges and difficulties created by the current credit crisis. At its core, Islamic finance is concerned with the deployment of capital in genuine commercial activities that will benefit the whole world. So far, the techniques used in Islamic finance, if applied and executed properly, have created a much closer relationship among the customer, the financier, and the asset. In both principle and practice, Islamic finance prohibits the creation of debt through direct lending and borrowing, thus prohibiting excessive leverage, which is a root cause of the financial crisis. This paper highlights the strengths of Islamic finance in the context of the current financial and economic crisis. This paper examines whether Islamic finance could help to provide an alternative approach to the problems that led to the crisis that would prevent the repetition of a similar crisis in the future.   Keywords: Islamic finance; Islamic financial system; financial crisis; profit-loss sharing; risk management.

Since being introduced in 2000, the Job Demands and Resources (JD-R) model (Demerouti, Bakker, Nachreiner & Schaufeli, 2000) has been studied extensively in various Western countries. Although the JD-R proposition is not proscriptive about specific demands and resource variables, scholars have used common variables as demands (e.g. workloads, deadlines), and as resources (e.g. support). The question is whether the common variables in the JD-R model that had their origins in Western formulations are applicable in developing countries. In this paper, based on grounded theory, we conducted focus group interviews to investigate specific variables that may apply in Malaysian workplaces. Two focus group interviews (N=13) were conducted with two groups of respondents (managers and non-managers) who worked for private and public sector organizations. Data were analysed using a thematic content analysis strategy. The study found that new variables (e.g. organizational politics, bureaucratic factors) emerged as new demands not generally explored in JD-R research, whereas similar demands were identified at a job-task level (e.g. deadlines). Regarding resources these were mainly identified as in other Western research (e.g. support). Job challenge and exploring new things were identified as pleasurable aspects of work. This finding suggests that using qualitative methods is crucial to exploring the psychosocial concept of stress at work to uncover cultural differences that are apparent between Malaysian and Western employees .
