Published: November 2020

At the present stage of the development of society, the transformation of social consciousness, there is a transition from a «consumer» attitude to the environment towards an active eco-humanistic position, the nature of expedient activity. The ecocentric paradigm as a certain theoretical and methodological model allows to fill the educational process with a set of ideas, views, motivations that illuminate the ecological side of being, namely the practice of optimal relations in the dyad «nature – man». The problematic of this article is timely and relevant, which is confirmed by the activities of international organizations that promote the greening of education, and the documents of the regulatory legal support for environmental education in Ukraine. The article analyzes the results of research of modern conceptual and program documents of preschool education and current programs of education, upbringing and development of preschool children, such as: Basic component of preschool education in Ukraine, «Sunflower», «I am in the world», «Confident start» , «Child», «Child in preschool years», «Ukrainian preschool», «About yourself it is necessary to know, about itself it is necessary to take care» «Treasury of morality», «World of childhood», «Path», «Preschoolers – education for sustainable development» . According to the objectives defined in the programs, the identified problem is discussed mainly in the context of environmental education or greening of the educational process. Content analysis of the programs allows to conclude that in the current documents the problem of education of environmentally sound behavior in children is defined as key and relevant, but it requires further scientific substantiation, establishes preconditions for the study of the conditions and technologies of its practical implementation in the space of preschool education, and in the process of training specialists. Key words: environmentally sound behavior, preschool children, current programs.

Authors:   Одеський торговельно-економічний інститут Київського національного торговельно-економічного університету, BENKOVSKA N.
Published: November 2020

The article is devoted to the problem of formation of motivation for learning foreign languages by higher education applicants. Various motivational approaches are considered. Practical experience convinces that the most important thing in learning a foreign language is the motivation of higher education applicants. Motivation is the most indisputable and well-studied factor in the success of learning in general and learning a foreign language in particular. It is the trigger for any activity, be it work, communication or cognition. The motive should be presented both at the beginning of the class and in the creation of a system of motives for each of its individual stages. The motive should be the point of support at which the content of the lesson is built. No one, even a highly qualified teacher, will achieve the desired result if his or her efforts are not aligned with the motivational basis of a particular learning process. Any activity or individual act is not motivated by a particular motive, but by a complex of motives, that is, it is motivated. In the context of research, motivation is seen as a hierarchical system of internal and external motives. The motivational sphere refers to a set of stable motives that are in a certain hierarchy and express the orientation of the individual. It is substantiated that the influence of emotional factor on educational activity is ambiguous, it depends on certain conditions. The process of professional interest formation has certain regularities and stages. The article also determines that work based on communicative principles has advantages over a theoretical approach to language learning. Generally speaking, in order to achieve the result effectively, it is necessary to provide a differentiated approach to learning a foreign language. In the result of the research it was concluded that purposeful work in the process of learning foreign languages to develop not only external stimuli but also internal motivations has a positive tendency. A deeper, more detailed knowledge of higher education applicants opens up more opportunities for the teacher to use a variety of content and form tasks that have a positive impact on the formation of professional interests. Keywords: motivation, motive, classification of motives, foreign languages, applicants for higher education.

Authors:   Russian University of transport, Russia, Rudneva S.
Published: November 2020

The article is devoted to the issue of providing medical care to railway workers after the February revolution of 1917 in Russia. Social transformations of the revolutionary period also affected railway transport, affecting, among other things, the medical and sanitary issue. The purpose of the study was to study the changes that took place in the structure of medical and sanitary Affairs in railway transport in 1917. Since it existed before the February revolution of 1917 railway medicine could not satisfy the railway workers, and they considered the situation of medicine on the Railways abnormal. Railway workers clearly recognized the need for a radical reorganization of the formulation of railway medicine. They expressed their wishes that this issue should receive comprehensive coverage at the all-Russian Railway Congress, and that not only doctors, but also middle and Junior medical personnel of other categories (paramedics, midwives, pharmacists, disinfectants, etc.) should be invited to participate in the railway medicine section, as people who are closer and more familiar with the needs of railway workers. As a result of the research, the article shows that the all-Russian constituent railway Congress, held from July 15 to August 25, 1917, in Moscow, contributed to the formulation and progress of scientific and sanitary Affairs that served the interests of railway workers, taking into account the specifics of the revolutionary period.

Published: November 2020

The history of civilization is inseparably associated with the development of high-quality materials technology [1]. Modern materials science, aimed at the production of the materials with special properties, is connected with the fundamental and applied science of nanotechnology which studies the laws of physical and chemical nano-sized systems. Almost all nanosystems are obtained under the conditions far from equilibrium. It allows achieving spontaneous nucleation, and to avoid growth and aggregation of the formed nanoparticles. Studies have shown that nano-based materials have new and sometimes unusual properties [2]. It is known that for conventional materials the greater the strength of the material the less its ductility. In nanomaterials, a new paradox [3] of strength and ductility (a simultaneous increase in strength and ductility) has been discovered. In addition, nanomaterials have a higher fracture toughness and substantial wear resistance. The physical nature of the new phenomenon is connected with the change of micromechanisms of deformation, when, along with the motion of lattice dislocations at the boundary of formed nanograins, grain-boundary glide occurs [4]. Additives to operating media are widely used in mechanism’s systems. In particular, the reliability of friction units is determined in many respect with the presence of antiwear and boundary additives in lube oils. The transition from micron- to nano-sized additives is being widely implemented in technology at present. In this paper, we have analyzed the effectiveness of the utilization of nanodispersed substances and their compounds in order to increase the service life of the ship’s equipment.

The article presents the results of numerical simulation of a Venturi scrubber for purifying contaminated gases from SOx emitted into the atmosphere by marine engines. To model aerodynamics, a solid-state model of a Venturi scrubber was developed. Geometrical parameters and standard models are designed to ensure that they are stowed in clean ship systems. At the first stage, they reached the bottom of the gas stream into the scrubber while feeding the obsolete gas in an amount of 32 m3 /s. On the basis of the obtained model of air flow graphs of velocity and pressure distribution along the axis of the Venturi scrubber were constructed. To determine the rational volume of steam to be fed to the scrubber to ensure a uniform distribution of it on the apparatus, studies of the distribution at different amounts of steam.The study was conducted for three modes of operation of the scrubber, which differ in the amount of saturated steam supplied to the apparatus (1, 5, 10 m3 /s). The simulation results allowed us to analyze the distribution of gas velocities and pressures in the scrubber, the efficiency of spraying and mixing of the gas stream and steam. Based on the analysis of hydrodynamics, the rational mode of operation of the scrubber is determined (steam supply – 10 m3 /s). Further increase in the amount of steam can be considered impractical due to the fact that the gas velocity of the apparatus is greatly increased, which in turn leads to increased resistance of the apparatus and the leakage of dust. The result of the early analysis is the transition to early models of purification systems based on the Venturi scrubber. The developed model can be used as a separate unit in large models of cleaning systems, which include several types of scrubbers for various industries.

This study introduces computerized model for evaluation of corporate performance for companies traded in the main world stock markets. The main contribution of this study is to utilize a “Soft Regression” modeling tool, which is a soft computing tool based on fuzzy logic in financial statement analysis. Specifically, the tool is used to identify the most important financial ratios explaining the performance (as reflected by Operating Income Margin) of publicly traded companies, belonging to the manufacturing industries 2000–3999. We used data extracted from the XBRL database for years 2012 to 2016. The main results and conclusions of the study are: 1. The study identified relevant financial ratios for the manufacturing industry. It also revealed the relative importance of the various categories of financial ratios. 2. Detailed comparison of the results for 2012 and for 2016 indicated high degree of consistency and stability over time. 3. Not all financial ratios are equally relevant for all industries. 4. Proxy variables belonging to the same category of financial ratios are interchangeable in our model. It does not matter, which of the ratios belonging to the same category are used, the results are very similar for both, 2012 and for 2016. 5. All the resulting indicators imply that the model is highly reliable and robust. The main contribution of this study is to present a soft computing modeling tool based on fuzzy logic which is intuitive, stable and not based on restrictive assumptions.

Background: Some individuals with Parkinson’s disease (PD) experience working memory and inhibitory difficulties, others learning and memory difficulties, while some only minimal to no cognitive deficits for many years. Objective: To statistically derive PD executive and memory phenotypes, and compare PD phenotypes on disease and demographic variables, vascular risk factors, and specific neuroimaging variables with known associations to executive and memory function relative to non-PD peers. Methods: Non-demented individuals with PD (n = 116) and non-PD peers (n = 62) were recruited to complete neuropsychology measures, blood draw, and structural magnetic resonance imaging. Tests representing the cognitive domains of interest (4 executive function, 3 memory) were included in a k-means cluster analysis comprised of the PD participants. Resulting clusters were compared demographic and disease-related variables, vascular risk markers, gray/white regions of interest, and white matter connectivity between known regions involved in executive and memory functions (dorsolateral prefrontal cortices to caudate nuclei; entorhinal cortices to hippocampi). Results: Clusters showed: 1) PD Executive, n = 25; 2) PD Memory, n = 35; 3) PD Cognitively Well; n = 56. Even after disease variable corrections, PD Executive had less subcortical gray matter, white matter, and fewer bilateral dorsolateral-prefrontal cortex to caudate nucleus connections; PD Memory showed bilaterally reduced entorhinal-hippocampal connections. PD Cognitively Well showed only reduced putamen volume and right entorhinal cortex to hippocampi connections relative to non-PD peers. Groups did not statistically differ on cortical integrity measures or cerebrovascular disease markers. Conclusion: PD cognitive phenotypes showed different structural gray and white matter patterns. We discuss data relative to phenotype demographics, cognitive patterns, and structural brain profiles.

Published: November 2020

We formalise and study multi-agent timed models MAPTs (Multi-Agent with Periodic timed Tasks), where each agent is associated with a regular timed schema upon which all possible actions of the agent rely. MAPTs allow for an accelerated semantics and a layered structure of the state space, so that it is possible to explore the latter dynamically and use heuristics to greatly reduce the computation time needed to address reachability problems. We use an available tool for the Petri net implementation of MAPTs, to explore the state space of autonomous vehicle systems. Then, we compare this exploration with timed automata-based approaches in terms of expressiveness of available queries and computation time.

Evaluation of Seedling Establishment Palatability and Acceptability Tests of Groundnut Seeds as Influenced by Levels of Whole Powder of Hyptis suaveolens L. Poit and Climatic Conditions
Authors: C. S. Oaya , K. B. Omar , I. Hammangabdo
Published: November 2020

The tests for the evaluation of seedling establishment, palatability and acceptability were carried out at the Teaching and Research Farm of the Department of Agricultural Technology and the Food Laboratory of the Department of Home and Rural Economics, Adamawa State College of Agriculture, Ganye, Adamawa State. The experimental designs used were Randomized Complete Block Design and the Completely Randomized Design. Some of the parameters measured were percentage seedling establishment, palatability, and acceptability tests. The highest mean percentage seedling establishment was observed in 12.00g levels of H. suaveolens whole powder treated shelled groundnut seeds (97.67, 97.00, and 94.00) at the three periods of storage. Percentage seedling establishment decreased with a decrease in levels of H. suaveolens whole powder. One of the major constraints to the use of plant materials as an alternative to synthetic insecticides is the issue of standardization in dosage of application. This work has suggested that, if groundnut seeds are to be used for sowing, they should be stored with a 12.00g level of H. suaveolens whole powder for every 300.00g for three months. However, if they are to be used for consumption, they could be stored with a 6.00g level of H. suaveolens whole powder for every 300.00g for at most three months. There was no significant difference between treated and untreated shelled groundnut seeds at the three periods of storage on the acceptability and palatability score of cooked groundnut at all dosages of application. All treatments were within the acceptable score rates even though the two rates of the synthetic insecticides, actellic dust were at the lowest acceptable score rate. The finding also showed that acceptability and palatability decreased with an increase in dosage of application. The periods of storage also had a significant impact on the mean percentage seedling establishment. It was observed that there was a higher percentage of seedling establishment when shelled groundnut seeds were stored from November- January. At this period of the year, the temperature and humidity are usually low and this might have necessitated the high state of inactivity and low performance of the bruchids compared to other periods of storage within the year.

The Stock Market’s Reaction to Strict Environmental Inspection: Evidence from Heavily Polluting Listed Companies in China
Authors: Tingting Xie , Yong Wang
Published: November 2020

As an important part of the new environmental governance system in China, the policy effect of Central Environmental Inspection has gained more attention. Based on the data from heavily polluting listed companies in China, this paper examines the impact of Central Environmental Inspection on corporate value by using an event study approach. The result of the study demonstrates that the Central Environmental Inspection causes a general and significant negative impact on the corporate value of heavily polluting listed companies. More specifically, the market value of private firms and small-scale firms declined more than that of state-owned firms and big-scale firms. In addition, under the deterrent of the Central Environmental Inspection, political connections have no longer become the effective way for polluting firms to evade strict environmental regulation.

A bovinocultura tem uma atividade crescente em todo o Brasil, no entanto, a produção desses ruminantes é prejudicada pelas helmintoses, por causarem retardo no desenvolvimento dos animais, levando à baixa produtividade e, consequentemente, elevadas perdas econômicas. O controle do parasitismo por nematóides gastrintestinais é realizado principalmente com o uso de anti-helmínticos. A utilização intensiva desses medicamentos, uso de subdoses, diagnósticos incorretos e a falta de rotatividade de bases farmacológicas têm provocado um sério problema sanitário: a resistência dos helmintos aos fármacos. O teste OPG é uma ferramenta útil, prática, rápida e que não requer o sacrifício dos animais, muito utilizado para diagnóstico da doença e prescrição do tratamento correto. O presente estudo visa apresentar o diagnóstico e controle químico das principais helmintoses bovinas perante a literatura, com o objetivo de contribuir para o melhor desenvolvimento dos bezerros, boa produtividade e ganho econômico satisfatório do produtor.
Ascophyllum nodosum seaweed extract effect on morphology and cellulolytic ability of the fungus Fusarium oxysporum f. sp. vasinfectum

Published: November 2020

This work aimed to verify the effect in vitro, of Ascophyllum nodosum (AN) seaweed extract on the morphology and cellulolytic capacity of the fungus Fusarium oxysporum f. sp. vasinfectum (FOV). Thus, the fungus was placed in contact with different doses of the extract, being these: 0, 0.5, 1.0, 2.0, 4.0 and 8.0%. It was verified that the product, with increasing doses, progressively induced mycelial growth of the fungus, as measured by the diameter of the colonies and fresh mass of mycelium grown in PD (potato-dextrose) culture medium. This result was also corroborated by the progressive increase in the activity of the β-1,3-glucanase and chitinase enzymes required during the hypha elongation process. However, the AN extract progressively reduced FOV sporulation with increasing doses. Furthermore, the cellulolytic capacity of the phytopathogen was significantly reduced in the presence of the algae extract, which was measured by the activity of the enzymes endo-β-1,4-glucanase, exo-β-1,4-glucanase and β-glucosidase. Thus, these facts constitute important information for the management of fusariosis, since the inhibition of sporulation and decreasing degradation capacity of the cellulose by the pathogen, can translate into declined disease in compatible host-pathogen interactions.
Gender differences in fruit production and selection of avocado and banana varieties: Case study at Wondo Genet and Wondo Woredas, Southern Ethiopia
Authors: Feyisa Tamirat G. , Megersa Habtamu G.
Published: November 2020

This study was designed to assess differences in gender roles and preferences of female and male-headed fruit producers regarding the selection of avocado and banana varieties. Two woredas were selected purposively based on the availability of avocado and banana production trends in the woredas. Then, a model avocado and banana producing female and male-headed households were identified and about 34 households were selected randomly from both woredas. A structured questioner was used to collect primary information from the selected households. The collected data were analyzed by STATA 12 software. The obtained results indicated that the male household members exceedingly participated in land preparation (93%), seedling preparation (90%), transplanting (90%) and weeding (76%) whereas, female household members highly participated in fruit collection (72%), transporting fruits to the market (83%), selling the fruit (90%) and deciding on money obtained from fruit sale (83%). The increased participation of female household members indicated that the contribution of female-headed households on many farming activities. The major criteria considered in selection of avocado varieties were plant height (75%), fruit size (75%), fruit yield (84%), fruit test (97%) whereas, fruit yield (91%), fruit color (72%), fruit test (94%) and fruit smell (53%) were important criteria for banana varieties. There were no statistically significant differences (P>0.05) in avocado and banana varieties selection criteria between female and male headed households. Therefore, breeders need not develop different avocado and banana varieties for female and male-headed producers. Gender based labor division in the study areas should be taken into consideration whenever technology is demonstrated and farmers' training is given on avocado and banana production technologies to ensure their effective implementation
Development of a Molecular Imprinting-Based Surface Plasmon Resonance Biosensor for Rapid and Sensitive Detection of Staphylococcus aureus Alpha Hemolysin From Human Serum
Authors: Andersson Tilde , Bläckberg Anna , Lood Rolf , Ertürk Bergdahl Gizem
Published: November 2020

Stapylococcus aureus is a common infectious agent in e.g. sepsis, associated with both high mortality rates and severe long-term effects. The cytolytic protein α-hemolysin has repeatedly been shown to enhance the virulence of S. aureus. Combined with an unhindered spread of multi drug-resistant strains, this has triggered research into novel anti virulence (i.e. anti α-hemolysin) drugs. Their functionality will depend on our ability to identify infections that might be alleviated by such. We therefore saw a need for detection methods that could identify individuals suffering from S. aureus infections where α-hemolysin was a major determinant. Molecular imprinted polymers were subsequently prepared on gold coated sensor chips. Used in combination with a surface plasmon resonance biosensor, α-hemolysin could therethrough be quantified from septic blood samples (n = 9), without pre-culturing of the infectious agent. The biosensor recognized α-hemolysin with high affinity (KD = 2.75 x 10-7 M) and demonstrated a statistically significant difference (p < 0.0001) between the α-hemolysin response and potential sample contaminants. The detection scheme proved equally good, or better, when compared to antibody-based detection methods. This novel detection scheme constitutes a more rapid, economical, and user-friendly alternative to many methods currently in use. Heightening both reproducibility and sensitivity, molecular imprinting in combination with surface plasmon resonance (SPR)-technology could be a versatile new tool in clinical- and research-settings alike.
Academic Tutors/Advisors and Students Working in Partnership: Negotiating and Co-creating in “The Third Space”
Authors: McIntosh Emily , Steele George , Grey David
Published: November 2020

In this perspectives piece, we argue that technology can be used to create and facilitate “Third Space” advising, via a model of “flipped advising” which focuses on the development of quality staff–student partnerships. “Third Space” advising, using technology, encourages students and staff to work together to create and validate knowledge, connect experiences, and improve the learning culture of the organization. It also aligns with Hockings’ (2010) definition of inclusive practice in learning and teaching. While so much focus has been on the development of the advisor, the concept of Students as Partners (SaP) and “The Third Space” offer important lenses within which to shift the focus of advising practice away from the development of advisors and toward the development of staff–student partnerships, with a view to improving the impact and outcomes on students themselves.
Investigation of Gene Sequence Divergence, Expression Dynamics, and Endocrine Regulation of the Vitellogenin Gene Family in the Whiteleg Shrimp Litopenaeus vannamei

Published: November 2020

In this report, we studied the vitellogenin gene family in the whiteleg shrimp Litopenaeus vannamei by transcriptomics, bioinformatics, and molecular biology methods. At least three moderately homologous vitellogenin (Vg) genes (i.e. LvVg1, LvVg2, and LvVg3) were identified in the genome. The deduced LvVg proteins consisted of a vitellogenin_N domain, a DUF1943 domain, and a VWD domain typical of most vitellogenins from oviparous animals. LvVg1 was the most abundant Vg expressed in the hepatopancreas and ovary of maturing females. Furthermore, multiple isoforms of LvVg1 were evolved presumably due to the need for rapid Vg production during the rapid phase of vitellogenesis. LvVg transcripts were detected in different larval stages, juveniles, and subadults. During the non-reproductive cycle, LvVg expression in the hepatopancreas peaked at the intermolt stages. During the female vitellogenesis cycle, a two-phase expression pattern of LvVg1 gene was observed in the hepatopancreas and ovary. Moreover, the eyestalk optic nerve, brain, and thoracic ganglion consisted of factors that differentially regulated the expression of the three Vg genes. In addition to their reproduction-related roles, Vg may also be involved in growth and molt-related processes. Phylogenetic analysis revealed the early expansion and separation of these Vg genes, and it is most likely correlated with the expansion of Vg’s function. In conclusion, the evolution of multiple LvVg1 isoforms and the acquisition of different Vg genes (i.e. LvVg2 and LvVg3) may occur universally in most decapods. Full information on the total number of Vg genes and precise knowledge on the expression pattern and endocrine regulation of each Vg during all life cycle stages are crucial for us to understand the roles of this emerging gene family in the control of shrimp reproduction and other non-reproductive processes.
