The creation of reservoirs in water streams leads to significant changes in the hydrological regime of water bodies: it allows smoothing the peaks of maximum water discharge during a flood period and regulating low-water flow. The creation of reservoirs with significant storage capacity makes it possible to solve a wide range of water-management problems, including the use of falling water energy for hydropower purposes, and maintenance of the uninterrupted water supply and navigation. Since constructed dams are usually operated by hydropower companies, the regulatory regime for the discharge of water into the lower pool is often determined by the daily electricity consumption regime. Intra-day variations in the volume of water discharges through hydroelectric power stations generate multidirectional streams in the upper pool, which can affect the operation of other water withdrawal systems. This paper considers the effect of intraday variations in water discharges into the lower pool on the dynamic and physical properties of the water mass in the region of the location of drinking water-intake heads of Perm city and the quality of the withdrawn water.

The results of scientific and economic experiment on the use of protein concentrate “AgroMatic” in feeding highly productive cows of Ayrshire breed during lactation have been provided in the article. The use of protein concentrate “Agro-Matic” in the rations of dairy cattle in the amount of 1,0 and 1,5 kg/head/day has been leaded to an increase in the content of cellulolytic microflora at the end of lactation compared with the control group. At the same time, the level of microorganisms that stimulate and promote immunity (bacilli, bifid bacterium) and suppress the development of pathogenic bacteria has been observed in high amounts throughout lactation in the experimental groups whose ration was put with protein concentrate. In the rumen content of cows have been receiving 1,5 kg/head/day of protein concentrate “Agro-Matic”, the increased content of bifid bacterium by 0,03 abs.% and bacilli by 0,91 abs.% has been noted. The inclusion of the maximum level of protein concentrate was characterized by the decrease in the number of pathogenic microorganisms like pathogens of mastitis and other diseases (lactobacilli, actinomycetes and enterobacteria). The total number of cellulolytic bacteria in the rumen content at the end of lactation when using 1,0 kg/head/day of protein concentrate in animals increased compared to animals that consumed the basic ration. The inclusion of protein concentrate throughout lactation contributed to the increase in the blood content of total protein and nitrogen of free amino acids. Thus, the use of protein concentrate during the feeding period increased the intensity of protein metabolism in animals. The inclusion of 1,5 kg of protein concentrate in the ration contributed to the increase in total protein in the blood by 4,6 g/l, at the level of 1,0 kg by 9,1 g/l (P > 0,95). The index of insemination when using protein concentrate in lactating cows has been decreased by 21,7 % and the duration of the period of open days by 28,2 days.

La misión de la Universidad es preparar a los estudiantes para la vida, es decir, prepararlos para enfrentar los desafíos que se les presenten a nivel personal y profesional. Si bien las necesidades de la especie humana no han cambiado, sus deseos sí. La realidad empresarial está en permanente evolución. La competividad empresarial, en su afán de satisfacer esos deseos y así, vender más y obtener utilidades, es cada vez más enconada, lo que convierte en prioridad para las facultades que forman a los nuevos empresarios, el desarrollo de la creatividad como prerrequisito para el desarrollo de la innovación. En las facultades de ciencias empresariales de nuestra universidad no se ha aplicado, hasta el momento, ningún programa académico que fomente el desarrollo de esta competencia. El objetivo de esta investigación es proponer, por lo tanto, una serie de actividades para el desarrollo de la inteligencia creativa. La metodología utilizada será bibliográfica y documental.

Authors: Vaca Cárdenas Mónica Elva , Antón Intriago Guido José
Published: December 2021

Innovar es aprender a emprender, el aula invertida se está utilizando cada vez más a nivel mundial. Desafortunadamente, la realidad del Bachillerato Ecuatoriano es que muy pocos docentes utilizan y aplican metodologías nuevas, innovadoras y emprendedoras, como el aprendizaje invertido.  El objetivo de esta investigación es analizar la efectividad del aprendizaje invertido en la asignatura de Emprendimiento y Gestión, a través de la utilización de las tecnologías y el cumplimiento de los pilares de este enfoque pedagógico.  Se trata de una investigación cuantitativa, para la cual se aplicó una encuesta a una muestra de docentes de Emprendimiento y Gestión del nivel de Bachillerato de los cantones Jama y Pedernales. Como principales resultados se obtuvieron que los docentes aplican los cuatro pilares del aprendizaje invertido de forma parcial. En cuanto a los recursos y medios tecnológicos, los docentes utilizan las Tecnologías de la Información y la Comunicación (TIC), entre las que se evidencian (redes sociales, el chat, los blogs y las aulas virtuales).  No obstante, desconocen ciertas herramientas tecnológicas del Aprendizaje y del Conocimiento, tales como: Kahoot, Quizizz, Cuadernia y Zoom, entre otros. Se concluye que el aprendizaje invertido aplicado por los docentes en la materia de Emprendimiento y Gestión, no logró la afectividad deseada por cuanto no se aplicó algunos indicadores de los pilares del aula invertida y desconocen recursos y medios tecnológicos que permitan mejorar el conocimiento, participación y empoderamiento en los procesos de enseñanza- aprendizaje. Por lo cual, se recomienda aplicar nuevas estrategias metodológicas para desarrollar la creatividad emprendedora y mejorar la efectividad del aprendizaje invertido.

A Printable and Conductive Yield-Stress Fluid as an Ultrastretchable Transparent Conductor
Authors: Lu Qianying , Zhou Yunlei , Yin Xiangfei , Cao Shitai , Wang Xiaoliang , Kong Desheng
Published: December 2021

In contrast to ionically conductive liquids and gels, a new type of yield-stress fluid featuring reversible transitions between solid and liquid states is introduced in this study as a printable, ultrastretchable, and transparent conductor. The fluid is formulated by dispersing silica nanoparticles into the concentrated aqueous electrolyte. The
as
-printed features show solid-state appearances to allow facile encapsulation with elastomers. The transition into liquid-like behavior upon tensile deformations is the enabler for ultrahigh stretchability up to the fracture strain of the elastomer. Successful integrations of yield-stress fluid electrodes in highly stretchable strain sensors and light-emitting devices illustrate the practical suitability. The yield-stress fluid represents an attractive building block for stretchable electronic devices and systems in terms of giant deformability, high ionic conductivity, excellent optical transmittance, and compatibility with various elastomers.

Assessment of cognitive factors and their relationship with burnout syndrome at different levels of medical education
Authors: Savelyeva Lyudmila А. , Kashapov Mergalyas М. , Savelyeva Marina I.
Published: December 2021

Consecutive completion of specialist and residency training is an important stage in the development of a young physician. Therapeutic activity implies emotional intensity and a great number of factors, causing stress. The syndrome of emotional burnout is not only a result of neuropsychological stress, but also a consequence of uncontrolled stress. The aim of the research was to determine influence of thinking styles, types of thinking and creativity level on factors of cognitive appraisal as predictors of burnout syndrome development in higher education trainees (specialist and postgraduate training programmes). The search of predictors of a burnout syndrome was carried out for a sample of 330 medical students and 50 physicians of the control group. As a result of research it has been revealed that trainees as well as practitioners have a practical style of thinking; postgraduate trainees more often use the combined one, students, figurative; and physicians, sign type of thinking; higher parameters of creativity are marked in postgraduate trainees over physicians. In general, students on specialty and postgraduate training programmes have less difficulty with most of the cognitive assessment factors. The correlation analysis showed as follows: for students, there were direct links of medium strength between the sign type of thinking and “strong emotionsˮ, emotional detachment, and “future perspectiveˮ; for postgraduate trainees, there were direct and inverse links of very weak and weak strength, which could be neglected. However, further factor analysis is required in order to assess the influence of certain factor on the development of emotional burnout syndrome in medical trainees.

retorno del talibán:
Authors: Pace Luca
Published: December 2021

La vuelta al poder del régimen del Talibán en Afganistán en agosto de 2021 ha causado hondas preocupaciones en la comunidad internacional en función de su experiencia como gobierno en el período 1996-2001 y por su alianza con organizaciones terroristas. Tras la intervención militar liderada por los Estados Unidos como consecuencia de los atentados del 11-S, perpetrados por Al-Qaeda, los talibanes se refugiaron estratégicamente durante años sin deponer sus aspiraciones de poder alcanzadas. Tuvieron que pasar veinte años de resistencia para su regreso al gobierno, aprovechando el acelerado proceso de retirada de las tropas norteamericanas anunciado por Trump y continuado por Biden. En este contexto de incertidumbre y expectativa, algunos países de Occidente han suspendido proyectos de cooperación internacional que tenían hasta entonces con Afganistán, mientras que otros como China y Rusia han buscado incipientes canales de acercamiento. Este trabajo busca abordar cómo la experiencia de gobierno del Talibán en el pasado ha generado nuevas inquietudes en la comunidad internacional tras su vuelta al poder, a punto tal de congelar los proyectos de asistencia a la espera de guiños favorables.

Mythological matter. Folklore Images in the Landscape of Latvian Textile Art in the Second Half of 20th Century
Authors: Legčiļina-Broka Rita
Published: December 2021

20.gadsimta 60.–80. gados Latvijas tekstilmāksla piedzīvoja uzplau- kuma periodu, kas bija saistīts ar politiskām izmaiņām, profesionālās izglītības reformu un jaunu tēlveides paņēmienu apgūšanu. Īpaša loma šī perioda tekstilmākslas attīstībā pieder Latvijas Mākslas aka- dēmijas profesoram Rūdolfam Heimrātam, kura ieviestā izglītības metode, kā arī personīgie radošie mērķi ietekmēja kopējo nozares vir- zību vairākas sekojošās desmitgades. Attīstot tekstiliju par pilntiesīgu mākslas darbu, kurā iespējams vizualizēt māksliniecisko tēlu sižetiski vēstošā nozīmē, izveidojās īpašs laikmetīgajai tekstilmākslai raksturīgs tēmu loks. Tajā nemainīgi aktuālu vietu ieņēma folklorā un tautas mītiskajos priekšstatos balstīti tēlojumi.
Raksta mērķis ir sniegt ieskatu folkloras tematikas atklāsmē Latvijas tekstilmākslā ietverot periodu, kad par vienīgo radošo metodi mākslā tika noteikts sociālistiskais realisms. Pētījumā tiek skaidrots kādi aps- tākļi ierosināja un veicināja folkloras tematikas izvērsumu tekstiljās, aprakstīta tēlu atveides tekstiliskā specifika, kā arī ir izveidots pārskats par raksturīgākajiem piemēriem, kuros konstatējama ne tikai nosau- kumā minēta atsauce uz folkloras avotu, bet arī plašākā simboliskā nozīmē attiecināms vēstījums.

Objective - Since the 70s, the Malaysian government has been focusing on sustainable development to improve society's economic well-being. In September 2015, Malaysia reaffirmed this commitment with the other United Nations countries by putting the 2030 Agenda for 17 Sustainable Development Goals (SDGs) into action and focusing on the bottom 40% households (B40). Unfortunately, the implementation of Goods and Services Tax (GST) on 1 April 2015 and followed by the Sales and Services Tax (SST) 2.0 on 1 September 2018 has impacted all income groups, especially the B40, with a claim that indirect tax is regressive and burdensome (MIER, 2018). Hence, the present study aims to analyse SST 2.0 tax burden using the elements of the guiding principles of good tax policy.

Methodology/Technique - In this quantitative study, the researchers distributed questionnaires to the B40, M40, and T20 groups throughout Malaysia. Evidently, the government should consider reducing the SST 2.0 tax rate to minimise the tax burden of all groups of income earners based on the ability to pay.

Findings - Furthermore, the efficiency of tax administrations is vital to strengthen the enforcement function in controlling the prices of goods and services. The findings can provide useful feedback to policymakers and tax authorities in designing a progressive indirect tax.

Novelty - The policymakers should also consider the new SST model and propose relevant social safety net programmes to enhance economic well-being and eradicate inequity.

Type of Paper - Empirical.

Keywords: SST 2.0; GST; Tax Burden; B40; Guiding Principles of Good Tax Policy.

Plow pan is one of the main obstacles to high production of agricultural plants in Chongqing, China. As a minimal tilling method, subsoiling can break the plow pan and help the growth of agricultural plants. There are two subsoiling methods: vibrating subsoiling (VS) and traditional subsoiling (TS). A soil model with upland field features in Chongqing was established for DEM-based simulation. The simulation was validated by field experiments, in items of soil looseness, coefficient of soil disturbance, and cross-section of tillage, the errors of the simulated and experimental values of the soil looseness and soil disturbance coefficient of TS and VS were 12.9% and 14.7%, respectively. Compared with TS, VS resulted in lower soil looseness, higher coefficient of soil disturbance, smaller width of upper furrow, and lighter damage of tillage layer, and no obvious overturn of soil blocks was observed for the VS. Compared with TS, vibration helps improve the tillage performance of subsoilers.

In order to reduce the power consumption of screw conveyor and to improve the productivity, this study investigated such mechanical characteristics of rubbed maize straw as coefficient of sliding friction, angle of repose, internal friction coefficient, cohesion, flow function value and compressible coefficient with respect to its moisture content and density. An experiment was designed and consists of a sliding friction characteristic test-bed, a direct shear apparatus, a self-made device with adjustable density and compression. The results showed that: the coefficient of sliding friction increases with the increase of moisture content and density; the angle of repose and internal friction coefficient each increases with increasing moisture content respectively; there is no significant effect between the moisture content and the cohesion of rubbed maize straw; the flow function value goes up with the increase of the moisture content; also the increase of the moisture content leads to the increased bulk density due to the reduced materials gap and the increased compression coefficient, which makes it hard to compress. The equation of pressure and density was found, and it is suitable for the analysis of compression characteristic of rubbed maize straw. The research results lay a theoretical foundation and a basis for the further study on mechanical properties of maize straw.

A self-propelled crawler and potato harvester was designed, with the terrain characteristics of both hilly and mountainous areas considered, to address the low degree of mechanization, markedly low potato harvesting rate, and high labor intensity of potato harvesting in hilly and mountainous areas. The harvester could complete the tasks of digging potatoes, separating them from the soil, transporting potatoes, and collecting them in a single operation. Finite element analysis was conducted on major parts, such as the digging shovel and the frame, based on the overall structure and working principle of the harvester. A field experiment was then conducted. The results of the finite element analysis showed that the maximum stress of the digging shovel was 37.969MPa, the maximum strain was 1.846×10-4, and the total deformation was 0.8041mm. These measurements were within a safe range. The field experiment results showed that potato harvesting rate, bruising rate, and damage rate were 98.54%, 1.51%, and 1.31%, respectively that is, higher than the national standards for potato harvesters. The potato harvester exhibited reliable walking performance and harvesting performance, which could provide a reference for research on the mechanization of potato harvesting in hilly and mountainous areas.
DRIVERS OF DIGITAL TRANSFORMATION IN APPROACHES TO MODERN TEACHING OF STUDENTS

The problem statement is connected with the paradoxical nature of modern academic reflection regarding the prospects not only for the development, but also for the survival of universities. Adherents of the alarmist approach justify the strengthening of the trend of academic capitalism, which represents a landslide increasing commercialization of all types of university activities, with a reduction in socio-humanitarian areas and the transition to an entrepreneurial post-academic university culture. Accordingly, the classical format of the university is declared to be dying, and the values of traditional academic culture are blurred and even ruined. Clarification and correction of concepts were required due to the fact, that digitalization is often considered as a process, and digital transformation is considered as the completion of the path of strategic and operational transformations that ensure competitiveness in the modern world. The authors insist that digital transformation is also procedural, so it would be more correct to designate the essence of these changes in modern higher education as an institutional purposeful transition to the latest technologies that provide opportunities for a variety of formats and personalization of the educational process. Clarification and expansion of the main drivers of digital transformation in modern higher education, in turn, indicate that the process of digital transformation, presenting intermediate results of achieving goals, will also remain open. The article presents an analysis of digital transformation in the practices of interaction between teachers and students, with an emphasis on the fact that the main goal of the teacher is his creative support, and the main goal of the student is the transition from the necessary development of modern specifics of the profession to the formation of a broader personal resource potential in the conditions of rapidly increasing changes. It is also important that digital transformation requires not only the consolidation of educational needs and skills during the life of university graduates, but also, first of all, their teachers. The authors note the discursiveness of the problem of the advantages and negatives of the digital educational environment, arguing that the understanding of modern students is focused on the need to implement early and systemic transformational changes in teaching and learning in the new digital landscape. The article concludes with updated conclusions and clarifies operational actions that contribute to achieving the goals of the transition to digital universities.
