Authors: Aripov Daler N. , Kuznetsov Ivan L. , Salakhutdinov Marat A. 
Published: August 2020

Introduction. At present, design and construction of all-composite structures with the use of pultrusion fiberglass profiles (PFP) are developing. The bearing capacity of all-composite structures is often limited by their node connections. Over the last two decades, many studies have been devoted to the operation of fiber-reinforced polymer (FRP) element nodes connected at right angles (or in the direction of pultrusion and across it). Frame construction nodes are formed by adjoining frame elements at different angles to the bands through gusset sheets. In accordance with the literature analysis, a small number of tests have been carried out to investigate connections at angles to the pultrusion direction. Existing design solutions of gusset sheets in FRP frame structures are mainly made of steel or composite material produced using other technologies (compaction method, pressure treatment method). This study focuses on the implementation of a node connection on unidirectional gusset sheets in which the fibers are positioned at the angle of 0°. Taking into account the specific features of the material, the gusset sheet design in frame structures has been adapted to the properties of pultrusion fiberglass. The purpose of this study is to increase the efficiency of PFP gusset sheet use in frame structures based on the specifications of this material.
Materials and methods. The adaptive method was used when designing the node connection design on the frame structure gusset sheets. The material of the trapezoidal steel truss is changed to the composite material while retaining the original design solution. Subsequently, the structure is upgraded to take into account the properties and features of the composite material.
Results. The main results of the study involve determining the factor of safety of pultrusion fiberglass at different angles to the direction of force. In order to increase the bearing capacity of the element node connection, various gusset plate design solutions are provided, which take into account different forces in the frame structure elements.
Conclusions. When designing PFP constructions, features of the material must be taken into account. Replacing traditional materials with composite without adjusting the design layout and upgrading the structure leads to increased material intensity.

Introduction. The choice of an effective antiscalant is an issue that all industrial enterprises have to face, as the operating costs value depends on it. Therefore, enterprises require experimental-industrial or at least laboratory tests before ordering a particular antiscalant. The process of selecting reagents for the maintenance of reverse osmosis systems by industrial enterprises is accompanied by the evaluation of all significant factors, from the inhibition efficiency to the product price. However, the analysis of scientific and technical literature shows that only the inhibition efficiency is taken into account when evaluating antiscalants, while the effect of sediment on the operating pressure, permeate quality and performance reduction are ignored. The tests should be carried out under actual operating conditions or be as close to them as possible. Therefore, in order to determine effective dosages, it is necessary to conduct laboratory tests on “actual” water while taking into account the actual recovery rate. This article presents the results of comparison of inhibitory property of two antiscalants, carried out on “actual” water from an industrial enterprise. An estimation of the effect of antiscalant choice on the operating costs value was carried out. The dependences of Са2+ content and antiscalant adsorption on its dose are obtained. Over the course of experiments, effective dosages of antiscalants were determined.
Materials and methods. The following antiscalants were used as part of this research: “AminatТМK” (NPF “Travers”, LLC, Russia), Jurbysoft M422 (Jurbywatertech, Lithuania). The research was conducted using industrial roll filters (model RE 1812-80 CSM, R-80G) (CSM, Korea).
Results. Experimentally determined dependences of Ca2+ content on the filtrate output value of reverse osmosis systems at different antiscalant doses of 2, 4 and 6 mg/l were obtained. It was shown that during water treatment with antiscalant the latter is adsorbed on the crystal surface, and the higher the antiscalant dose, the more of it is adsorbed.
Conclusions. It was shown that at the same dosage the antiscalant “AminatТМK” is more effective at preventing sedimentation of calcium carbonate during the operation of membrane units.

Published: August 2020

The study focused on comparison on impact of HIV/AIDS patient’s characteristics on their blood pressure in Nigeria: a case of NAUTH, COOUTH and Onitsha general hospital in Anambra State. The blood pressure being the response variables are systolic blood pressure & diastolic blood pressure, while the predictor variables being the HIV/AIDS patient’s characteristics are age, baseline count, initial weight, present weight and CD4 count of HIV/AIDS patients. The R software package was employed to facilitate the data analysis. The Multivariate Regression Model of the two response variables (Systolic PB and Diastolic PB) was first fitted with the coefficient of determination of 31.88% and 46.80% respectively for NAUTH data, 27.9% and 37.98% respectively for COOUTH data and 97.35% and 57.15% respectively for general hospital, Onitsha data. The test on the significance of the parameters for the multivariate regression for NAUTH data revealed that age and baseline count of HIV/AIDS patients have significant relationship with systolic BP at 5% level of significance, whereas other predictor variables (initial weight, present weight and CD4 count of HIV/AIDS patients) are not significant, while in the second model, only age has a significant relationship with diastolic BP, whereas initial weight, present weight, baseline count and CD4 count of HIV/AIDS patients do not have significant relationship with diastolic BP at 5% level of significance. The test on the significance of the parameters for the multivariate regression also revealed that only age has significant relationship with systolic and diastolic BP at 5% level of significance, whereas other predictor variables are not significant for both COOUTH and general hospital Onitsha data. It was further revealed that the data collected from the general hospital Onitsha has the highest coefficient of determination (0.9735) with the lowest AIC (1348.944), BIC (1374.462) and residual standard error (2.587) for systolic blood pressure model which makes the data used in this study the most suitable for the model employed under the stipulated year of study. Also observed that the same data collected from the general hospital Onitsha has the highest coefficient of determination (0.5715) with the lowest AIC (1825.917), BIC (1851.435) and residual standard error (6.008) for diastolic blood pressure model which equally makes the data used in this study the most suitable. It is clear from the result obtained in this study that the data set collected from general hospital, Onitsha from 2003 to 2017 is most appropriate for the multivariate multiple linear regression models.
Using Crowdsourced Wikis to Teach an Online Undergraduate Course
Authors: Fisher John R , Allred Steve 
Published: September 2020

This study examined emergency service student use of wiki in an assignment to develop guidelines for preparing crisis communication plans in an online class. As a form of course evaluation, students were asked to respond to five questions about their experience in using wiki.Conclusions were drawn about the practicality of using wiki in teaching online. Students affirmed that collaboration leads to learning and knowledge acquisition. By engaging in collaboration, learners observe and improve upon weaknesses or gaps in learning. Students learn from each other by examining and improving the work of others. Students also viewed that using wikis to develop documents is a valuable skill to take into the workplace.A number of barriers exist that make using wiki in online teaching more challenging. It is more difficult to monitor and correct student actions online than in a face-to-face classroom. Most students hesitate to edit and change other student writing and so incentives need to be used to get students to edit each other’s work. Students should receive an orientation where they learn the purpose and benefits of wikis and receive instruction on how to use wikis. The study confirms much of the research on the topic of using wikis as a learning strategy. Also, the study shows that process is as important to learning as is outcome. Learning to use wiki is as important as producing a final document.

Published: September 2020

Beneficial properties of shade trees of tea plantations other than their medicinal properties have been extensively studied. This research was initiated to explore the properties of some shade trees with special emphasis on their antioxidant and antibacterial properties. Leaves from shade tree like Dalbergia sissoo (DS), Cassia siamea (CS), Derris robusta (DR), Leucaena leucocephala (LL), Acacia lenticularis (AL) and Melia azedarach (MA) were used for the study. Characterization of shade tree leaves by determination of moisture, crude fibre and ash content and tests of non polar – polar solvent extracts for steroid, tannins, cardiac glycosides and coumarin, free radical scavenging, ferric reducing power, NO scavenging activities, quantification of Flavonoids and antibacterial activity were conducted. The average moisture, crude fibre and ash percentage of shade tree plants were found to be 62.95, 11.28 and 1.86 respectively. Methanol, ethanol, acetone and ethyl acetate respectively proved to be the most potent solvent for various phytochemical extractions as it gave positive results for tests like tannin, steroid, cardiac glycosides and coumarin. AL (91.46%), DR (92.69%), LL (94.32%) and MA (93.34%) leaf extracts showed a high level of DPPH scavenging activity in their water extracts. In DS (88.11%) and CS (83.23%) maximum DPPH scavenging activity was observed in Diethyl ether and Methanol extracts respectively. Acetone extracts were more active than the water extracts in exhibiting ferric reducing power and NO scavenging activity. Summation of the quantity revealed that DS showed maximum presence of flavonoids and acetone as most potential for isolation of flavonoids. The decreasing order of summative antibacterial activity was recorded in DS, followed by CS, DR, AL, MA and LL. Chloroform showed the highest summative inhibition zone followed by ethanol, ethyl acetate, diethyl ether, acetone, water, hexane, benzene and methanol. The antioxidant and antibacterial potential of shade trees were established.
The concept of a digital transformation of a traditional university to a “digital university”
Authors: Kuzina G. 
Published: August 2020

One of the priorities of the government program “Digital economy of the Russian Federation” is the progressive development of the existing education system, which should provide the economy with competent personnel. In addition, this document declares the need to create a system of motivation for the development of the necessary competencies and participation of personnel in the development of the digital economy of Russia. All this requires the transformation of the classical educational system, which ultimately implies the creation of a “digital university”.According to the concept, proposed by the Agency for Strategic Initiatives together with Skolkovo University, the “digital university” will allow us to change the form and content of education in accordance with the requirements for new digital economy personnel. At the same time, the main emphasis should be placed on the individual trajectory of education, that is, collecting information not only according to the teacher’s assessment, but also collecting information in the student’s online course (what subjects the student was interested in, how he passed the intermediate tests, etc.). In addition, you need to create a specific set of services at the university. They should work in a similar way to the super services that are already being created in the Ministry of Digital Development, Communications and Mass Media of the Russian Federation for receiving public services online. So, the student will be able to get help and get registered in the military enlistment office in a single window mode, without having to go to the offices. In addition, changes are needed related to the content of education. So, along with the already developing segment of mass online courses, courses using AR and VR and virtual simulators should be introduced in universities. With the help of modern technologies, students will be able to learn the profession more effectively in practice.The article attempts to generalize the minimum set of necessary transformations of a classical university into a “digital” one and present their description.

El objetivo de la investigación fue conocer si el programa TALENTVEFT tiene algún efecto en el desarrollo de las inteligencias múltiples en niños. El estudio corresponde al método experimental, nivel explicativo y a un diseño cuasiexperimental de corte longitudinal. Se contó con la participación de 182 estudiantes, divididos en dos grupos: el grupo experimental y el grupo control. El grupo experimental participó en 4 sesiones de una hora durante 4 semanas (de una sesión por semana). El grupo control no participó en ningún taller realizado. Ambos grupos fueron evaluados antes y después (pretest y postest) de la intervención con el inventario de inteligencias múltiples del profesor de Armstrong, adaptado por Prieto y Ballester (Álvarez, 2014). Los resultados arrojaron diferencias estadísticamente significativas entre ambos momentos de medición a nivel de inteligencia interpersonal (t = 7,752 / p = ,000) e intrapersonal (t = 7,416 / p = ,000). Esto nos permite sugerir la efectividad del programa y dejar abierta la posibilidad de su replicación, considerando además la fiabilidad y validez de sus instrumentos de evaluación.

A nivel mundial existe una importante atención hacia el tema del cuidado del medio ambiente, y la investigación asumió este encargo social, proponiendo un Modelo de Gestión Educativa Ambiental para Fomentar la Cultura Sostenible del Manejo y Tratamiento de Residuos Sólidos, fundamentado en la Teoría del Pensamiento Complejo de Edgar Morin, las Leyes del Liderazgo de Maxwell y los procesos de Deming, La investigación fue de tipo descriptiva y crítico propositiva, partió de un estudio transversal que permitió diagnosticar la gestión educativa ambiental y el liderazgo en el manejo y tratamiento de residuos sólidos ejercido por los directores y la cultura ambiental de los docentes y estudiantes en las instituciones educativas estatales del nivel primario de la Ugel Sur de Arequipa. El muestreo fue no probabilístico intencional para el caso de los directores y probabilístico para los docentes y estudiantes, la muestra la constituyeron 90 directores, 354 docentes y 456 estudiantes del VI grado de primaria de 90 instituciones educativas de gestión estatal. Se concluyó que a pesar del conocimiento en temas ambientales tanto de docentes como estudiantes, no es suficiente para la práctica de una cultura del manejo y tratamiento de residuos sólidos, y constituye un agravante la deficiente gestión educativa ambiental por parte de los directores. Y se diseñó el modelo a partir de los resultados obtenidos en el diagnóstico que permitieron seleccionar las áreas específicas a trabajar e incluirlas en el Modelo, al mismo tiempo que el paradigma teórico asumido proporcionó tres categorías sustanciales como ruta para modelar la propuesta concretada en tres objetivos estratégicos y viabilizadas a través de tres proyectos.
