Improving health in an educational environment allows to gain greater control over the health of students. It includes a wide range of educational and methodological activities aimed at protecting and improving the health of subjects of the educational process and improving their quality of life through the correct organization of the educational environment, and not only prevention and correction. This policy should be supported by an appropriate regulatory framework that combines the stimulation of experience and knowledge based on high-quality evidence-based information, verified health evidence, develops intellectual assets and applies ethical standards in the practice of maintaining the health of students at the university. Partnerships between public health services of the Republic of Kazakhstan and higher educational institutions are obliged to identify and share responsibility for the health of the student community and solve problems that contribute to the development of key tasks in the field of protection and preservation of public health, requiring additional efforts and mobilization of resources of the higher education system. At the republican level the functions of monitoring public health risk factors in the conditions of training students in higher education are carried out. Scientific research in the field of public health, including measures to promote healthy lifestyles, makes it possible to predict their dynamics and assess the effectiveness and quality of educational services and implementation programs for the preservation of public health. The activities of higher educational institutions in the Republic of Kazakhstan are considered from the point of view of health as the main value. A healthy student community and its well-being are based on the consolidation of efforts and available methods of preserving and developing the health of future professionals.

The article is devoted to determining the place of information literacy in the structure of professional competence of special teachers. The analysis of the works of domestic and foreign researchers made it possible to reveal the specifics of the interpretation of the concept of “information literacy”, ideas about its meaning in the general training of future special teachers. Professional competence as a result of vocational education presupposes the presence of specific elements that serve as criteria for assessing the level of its formation. Indicators of information literacy are clearly expressed in characteristics that describe the current requirements for a future special teacher, and are part of the content of professional competence. The ability to satisfy one's own information needs, collect, exchange, store information and assess its quality are essential components of the general culture of a modern person. In the development of professionalism of future special teachers these abilities perform significant functions. The empirical research was organized in order to identify the degree of understanding in special educators necessary for effective teaching. The study involved 120 defectologists who studied at the Pavlodar Pedagogical University. The experiment is a survey of working special teachers, which was carried out using the author's questionnaire. The study showed a high need for practice in special teachers who have information literacy. The article discusses the development of information literacy as a fundamental component of the professional competence of special teachers through improving the organization of dual education.

The article is devoted to the problem of organizational and pedagogical conditions in the framework of trilingual education in the Republic of Kazakhstan. The authors consider the essence of the concepts of “conditions”, “pedagogical conditions”, “organizational and pedagogical conditions”, “structure of organizational and pedagogical conditions” in more detail. Psychologists consider the concept of “conditions” in the context of mental development through a set of internal and external causes that determine the overall psychological development of a person, accelerating and slowing it down, influencing the development process, its dynamics and final results. Pedagogical condition is a general scientific one, and its essence in the pedagogical aspect can be characterized in several provisions: 1. A condition is a set of causes, circumstances, any objects, etc. 2. The influence of conditions can accelerate and slow down the processes of development, education and training, as well as affect their dynamics and final results. 3. Caracterized complex influence on the developing, education and studying of a person. The organizational-pedagogical conditions and its’ structure were defined, from the perspective of language education, which is based on problem of investigation of the succession of the multiculturalism in the Republic of Kazakhstan.

Authors: Jenny Bruno
Published: August 2021

Unternehmen realisieren ihre zahlreichen Innovations- und Änderungsvorhaben in Form von Projekten. Das ist notwendig, um die Herausforderungen der Digitalisierung, der Marktdynamik und eines harten Wettbewerbs erfolgreich zu bewältigen. Der gewünschte Projekterfolg wird jedoch nur dann erreicht, wenn Projekte weitgehend auf einer professionellen, methodischen Führungs- und Durchführungsebene basieren. Und noch mehr: Das moderne Projektmanagement beruht auf einem umfassenden (zukunftsweisenden) Managementsystem. Die Effizienz dieses Systems besteht, neben der richtigen Integration, aus der optimalen Interaktion der einzelnen Systemelemente. So wird beispielsweise mithilfe der Projektabwicklung meist "nur" eine funktionale Veränderung erreicht, während ein zudem qualifiziert eingesetztes Changemanagement auch den psychologischen Veränderungsprozess, welchen alle Betroffenen durchlaufen müssen, auf eine professionelle Weise unterstützt. Dieses Buch zeigt auf, dass Projektarbeit wesentlich mehr ist als "trendy". Es vermittelt, unterstützt mit vielen Grafiken, echtes Projektmanagementwissen, unabhängig von der Fachrichtung und der Hierarchiestufe. Dank einer leicht verständlichen Sprache, prägnanten Lerninstrumenten wie Lernziele, Checklisten, Aufgabenstellungen, Musterlösungen und einem aufschlussreichen Fallbeispiel ermöglicht es, die komplexe Thematik des modernen Projektmanagements auf eine interessante Art und Weise im Selbststudium zu erlernen.

Stepwise increase of upper limb muscle activity induced by progressive 4 positions of a handstand training
Authors: Kinoshita Kazuaki , Hoshino Yuichi , Yokota Naoko , Hashimoto Masashi , Nishizawa Yuichiro , Kida Noriyuki
Published: August 2021

BACKGROUND:

Handstand is the most important fundamental skill in gymnastics. A gradual and well-balanced increase in muscle loading in a manner is preferred for young beginners and/or recovering gymnasts to safely achieve the muscle strength required to perform a stable handstand.

OBJECTIVE:

To examine upper limb muscle activity during different levels of handstand training positions.

METHODS:

This study utilized four different positions for progressive handstand training; namely, the 90, 135, elbow stand, and handstand positions. The activities of eight upper limb muscles (upper, middle, and lower trapezius; serratus anterior; anterior and middle deltoid; infraspinatus; and latissimus dorsi were measured by surface electromyography (EMG) for each position. The percentages of EMG in each muscle compared to the values during maximum voluntary contraction were calculated and compared between the positions.

RESULTS:

Muscle activity around the shoulder increased gradually throughout the progression of the four handstand training positions. Furthermore, the muscles required for scapular stabilization, such as the upper and middle trapezius and serratus anterior muscles, were activated at levels similar to those for a handstand without performing this movement.

CONCLUSIONS:

A progressive handstand training program of four different positions resulted in gradual and well-balanced increases in muscle activity.

Associations between psychosis risk and emotional distress disorders with cortical surface morphometry
Authors:   , Hua Jessica P. Y.
Published: August 2021

[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Neuroimaging studies have consistently found structural cortical abnormalities in schizophrenia, especially in structural hubs. However, it is unclear what abnormalities predate psychosis and whether abnormalities are related to psychosis risk-related behavioral performance and symptoms. In Study 1, I examined cortical morphometry of psychosis risk (n = 18) and control (n = 19) groups. Overall, the psychosis risk group exhibited decreased volume in multiple structural hubs, left rostrolateral prefrontal cortical and right pericalcarine hubs, as well as hypogyria in a right posterior midcingulate cortical hub. Morphometric measures in these same regions were associated with poorer probabilistic category learning, a behavioral measure strongly associated with psychosis risk. Additionally, the psychosis risk group exhibited multiple other abnormalities in visual structural hubs. APS hallucinations and delusions severity was also associated with hypogyria of the temporal lobes and right middle frontal cortex. In contrast, hypergyria associated with recent distress was not associated with psychosis risk. In Study 2, to further examine associations with distress, I examined cortical morphometry and ambulatory assessment daily-life emotion and behavior dysregulation in a non-psychotic emotional distress disorder group (n = 28). Recent distress was associated with hypergyria in a region not associated with psychosis risk. Furthermore, daily-life dysregulation was associated with gyrification abnormalities, including regions involved in emotion regulation and inhibitory control. Current results suggest that structural abnormalities, especially in structural hubs, predate psychosis and are associated with poor psychosis risk-related learning and APS severity. This research also found that gyrification is associated with daily-life dysregulation in emotional distress disorders.
From the lab bench to the fuel tank : development and analysis of novel adsorbents for hydrogen and natural gas storage
Authors:   , Stalla David E.
Published: August 2021

Hydrogen and natural gas offer a promising avenue towards reducing greenhouse gas emissions in the transportation sector; however, storage poses a non-trivial challenge, with current systems requiring prohibitively large and bulky hardware. Adsorbent media, notably nanoporous activated carbons, have seen significant development towards making such solutions viable, but none have yet to demonstrate the performance necessary to supplant existing technologies. Presented here is the synthesis and optimization of two materials designed to be especially competitive, as well as the techniques implemented to characterize them. Boron doping of nanoporous carbons, with the incorporation of carrier gas assisted deposition, is proposed to enhance the surface's binding potential while maintaining the integrity of the inherent pore space. This process explicitly demonstrates complete infiltration of the carbon's internal volume and facilitates boron substitution to a greater extent relative to other similarly-produterials. Carbon nitrides, specifically the graphitic isomer g-C[subscript 3]N[subscript 4], are theorized to produce adsorbents with surface areas and binding energy in excess of activated carbons via facile synthesis. Crystallographic investigation reveals the previously-reported synthesis methods instead produce a polymeric structure; this results in a highly-aggregating bulk that strongly resists exfoliation.
The Effect of School Space on Pedagogical Practices and Students’ Learning Outcomes: A Review of Scientific Sociological Literature
Authors: Lagiou Archontoula , Asimaki Anna , Koustourakis Gerasimos , Nikolaou Georgios
Published: August 2021

School space is an important factor in the realization of educational work since it shapes the material conditions for the implementation of the educational process. The aim of this paper, which focuses on a review of contemporary sociological scientific literature, is to investigate and highlight the effect of school space on the shaping of pedagogical practices, as well as on the pupils’ learning outcomes. Study and analysis of the content of research findings and relevant scientific papers reveal that school space is chiefly “mono-functional” and that both teachers and pupils remain caught up in the implementation of what are largely traditional pedagogical practices. School space clearly needs to be adapted to the new pupil-centered pedagogical methods, and this can only be achieved through the initiative and agency of the teachers. Finally, it is also clear that the pupils’ learning outcomes are to a great extent linked to the position they occupy in the space within the school classroom.
Kibernetički model komunikacije u nastavi - osvrt na povratnu informaciju
Authors: Grozdanović Milan J. , Marković Jelena B.
Published: August 2021

The focus of this paper is the cybernetic model of communication, ie feedback and its importance in the teaching process. It has been noticed that teaching in the classroom is performed mostly one-way, i.e., from teacher to student. Such communication does not contribute to a valid exchange of information, and the paradigm of communication in the classroom is slowly moving towards two-way communication with a focus on feedback. The cybernetic model of communication gives us the possibility of correction during communication, because the feedback provides insight into how the message was received, and accordingly we can further conceptualize and organize more successful communication.
A METHODOLOGY TO SELECT ASYNCHRONOUS TRACTION ELECTRIC DRIVE FOR INNOVATIVE METRO ROLLING STOCK
Authors: Sulym A.
Published: August 2021

The paper deals with the justification of the need to use an asynchronous traction electric drive on the metro rolling stock. The advantages of using an asynchronous traction electric drive in comparison with a DC commutator motor drive are formulated. The characteristics of modern innovative metro rolling stock with asynchronous traction electric drive of domestic and foreign production are analyzed. Aspects of the choice of a variable frequency asynchronous traction electric drive for innovative rolling stock are formulated and the existing typical algorithm of such choice is given. The main reasons for the irrational choice of traction asynchronous electric drive for the metro rolling stock are considered and the consequences of such a choice are analyzed. It is proposed to improve the methodology for selecting a variable frequency traction asynchronous electric drive for the metro rolling stock in terms of such an important operational factor as the specific cost of electrical energy for traction. The rational parameters of the variable frequency asynchronous traction electric drive according to the proposed procedure for the specified characteristics of the metro rolling stock are specified. The reserves of energy savings for the given conditions due to the introduction of an asynchronous traction electric drive with rational parameters on the innovative rolling stock are determined. It is established that the efficiency factor of the asynchronous traction motor significantly affects the specific electric energy consumption for the metro rolling stock traction and operating costs.
MODEL OF DEFORMATION OF FIBROUS MATERIALS OF MULTIDIRECTIONAL REINFORCEMENT WITH NONORIENTED FIBERS
Authors: Shikula E.
Published: August 2021

A model of deformation of multidirectional reinforcement fibrous materials with differently oriented fibers is proposed. The solution to the problem is built in two stages. At the first stage, the known properties of fibers and binder are used to determine the effective thermoelastic properties and stress-strain state of the subsystem with fibers oriented in a certain way relative to the main coordinate system. It is based on stochastic differential equations of the physically nonlinear theory of elasticity using the method of conditional moments. At the second stage, using a given distribution function based on the Voigt scheme, a model of deformation of the entire system is constructed from the calculated properties of the subsystems. Strain curves are obtained for simple loading, and the deformation of materials at uniform orientation of fibers is investigated. It was found that a fibrous composite material with differently oriented fibers in a macrovolume is isotropic, and its effective thermoelastic constants substantially depend on the volumetric content of fibers.
INVESTIGATION OF THE DYNAMIC LOAD OF THE JOINT-PLATFORM OF THE JOINT TYPE FROM ROUND PIPES LOADED BY TANKER CONTAINERS
Authors: Fomin O.
Published: August 2021

The dynamic loading of the load-bearing structure of the articulated platform car made of round pipes loaded with tank containers was determined. The research was conducted by mathematical modeling. The solution of the equations of motion is carried out in the MathCad software package. It is established that under the influence of a longitudinal force of 2.5 MN on the front stops of the autocoupling, the acceleration on the first section of the platform car is 27.7 m/s² from the side of the force application, and on the second - 24.4 m/s2. To reduce the dynamic load of the load-bearing structure of the platform car, the possibility of using the concept of a harness device on it as an alternative to a typical self-coupling device is considered. The quenching of the kinetic energy of the impact is carried out due to the viscous resistance forces arising in the concept. The proposed implementation allows to reduce the dynamic load of the load-bearing structure of the platform car by 10% compared to the use of a standard self-coupling device. The conducted researches will promote creation of innovative designs of cars-platforms and increase of efficiency of use of railway transport.

El presente artículo pretende analizar la coyuntura financiera de México en la actualidad, para explicar mediante una investigación documental si la pandemia por coronavirus –originada en Asia en diciembre de 2019 y propagada en nuestro país en marzo de 2020–, ha sido un factor relevante capaz de acelerar y profundizar aún más la tendencia negativa de crecimiento económico, que dificultará en el corto y mediano plazo, la ardua tarea de lograr un mejor posicionamiento económico en el escenario internacional.

Investigaciones realizadas a través del centro de transparencia de la Universidad de Sonora, describen que los municipios del sur de Sonora no cumplen con la Ley de Transparencia y acceso a la información pública, por otra parte está la falta de administración de la información para hacer del conocimiento público la rendición de cuentas de cada uno de los municipios; existen comités que definen las políticas de funcionamiento del comité de transparencia, a nivel estatal y municipal, siendo su actividad primordial lo que está estipulado en su objetivo específico que es: “acordar las políticas necesarias en cuanto a la instrumentación, coordinación y supervisión de la ley de transparencia, lo mismo para la obtención de la información en términos de las disposiciones aplicables en la materia, que garanticen el derecho de acceso a la información”, para cualquier ciudadano. En todo este tiempo desde que se puso en marcha este escenario de transparencia, al menos en los municipios del sur del estado no se ha cumplido cabalmente con las obligaciones de la ley. Esta situación que se vive en los ayuntamientos de los municipios del sur de Sonora, hace pensar que el contexto de donde se parte para aplicar la ley de transparencia, no son los adecuados o pertinentes para el nivel de crecimiento social de una población encarecida en todos los aspectos que conforman su diario vivir, por lo que se requiere de un análisis de los procedimientos de aplicación de la ley por los responsables de los departamentos encargados dentro de los ayuntamientos mencionados.

El objetivo del presente trabajo fue conocer la distribución de las especies de Passalidae en un gradiente altitudinal en el Soconusco y relacionar la disponibilidad y características de la madera muerta con la riqueza y abundancia de pasálidos. Se seleccionaron nueve sitios con diferente altura sobre el nivel del mar (10-3000 m) y se usaron cinco transectos lineales de 50 m para la toma de datos en cada uno de los sitios. Cada transecto tuvo cinco puntos de muestreo, donde se midió diámetro y largo de la madera, estado de descomposición y presencia de pasálidos. Para determinar diferencias estadísticas se aplicó una prueba de Kruskal-Wallis para el volumen de madera y tablas de contingencia para la asociación de las tribus de pasálidos con los diferentes estados de descomposición. En total se registraron 15 especies de Passalidae correspondientes a nueve géneros y dos tribus de la subfamilia Passalinae. Se examinaron 224 piezas de madera con un volumen total de 10.54 m3, observándose una colonización del 13.8% de las piezas encontradas. La distribución de pasálidos fue diferente en todo el gradiente altitudinal, mostrando una alta riqueza y abundancia en dos sitios con hábitat conservado (bosque mesófilo de montaña). El volumen de madera muerta fue estadísticamente diferente entre los sitios, destacando los dos sitios (1500 y 2220 m) por tener el mayor volumen de madera (principalmente del estado III). Se observó que el estado de descomposición sí determinó la colonización de los Passalidae, agrupando la mayoría de las especies los estados II y III. El microhabitat mayormente registrado fue el alboduramícola. Se observó que las prácticas agronómicas influyen sobre la comunidad de pasálidos, principalmente en los sitios que tuvieron cultivo de cacao y café.

Understanding wet tear strength at varying moisture content in handsheets

A laboratory study was conducted looking at the effects of moisture content on wet tear strength in handsheets. Three different wetting techniques were used to generate the wet tear (Elmendorf-type) data at varying moisture levels, from TAPPI standard conditions (dry) to over 60% moisture content (saturated). Unbleached hard-wood and softwood fiber from full-scale kraft pulp production were used. The softwood fiber was refined using a Valley beater to reduce freeness. Handsheets were made with a blend of hardwood and softwood and with refined softwood, without the addition of wet-end chemistry. The resulting grams-force tear data obtained from the test was indexed with basis weight and plotted versus both moisture content and dryness. As moisture content levels in the handsheets increased, the wet tear strength also increased, reaching a critical maximum point. This marked a transition point on the graph where, beyond a critical moisture content level, the tear strength began to decline linearly as moisture increased. This pattern was repeated in handsheets made from a blend of hardwood and softwood and from 100% refined softwood.
Co-ground mineral/microfibrillated cellulose composite materials: Recycled fibers, engineered minerals, and new product forms

Published: August 2021

When pulp and minerals are co-processed in suspension, the mineral acts as a grinding aid, allowing cost-effective production of mineral/microfibrillated cellulose (MFC) composite materials. This processing uses robust milling equipment and is practiced at industrial scale. The resulting products can be used in many applications, including as wet- and dry-strength aids in paper and board production. Previously, we have reported that use of these MFC composite materials in fiber-based applications allow generally improved wet and dry mechanical properties with concomitant opportunities for cost savings, property improvements, or grade developments. Mineral/MFC composites made with recycled pulp feedstocks were shown to offer at least equivalent strength aid performance to composites made using virgin fibers. Selection of mineral and fiber allows preparation of mineral/MFC composites with a range of properties. For example, the viscosity of such formulations was shown to be controlled by the shape factor of the mineral chosen, effective barrier formulations were prepared, and mineral/MFC composites with graphite as the mineral were prepared. High-solids mineral/MFC composites were prepared at 75% total solids (37% fibril solids). When resuspended and used for papermaking, these high-solids products gave equivalent performance to never-dried controls.
Black liquor evaporator upgrades— life cycle cost analysis
Authors: CANTRELL JAMES G.
Published: August 2021

Black liquor evaporation is generally the most energy intensive unit operation in a pulp and paper manufacturing facility. The black liquor evaporators can represent a third or more of the total mill steam usage, followed by the paper machine and digester. Evaporator steam economy is defined as the unit mass of steam required to evaporate a unit mass of water from black liquor (i.e., lb/lb or kg/kg.) The economy is determined by the number of effects in an evaporator train and the system configuration. Older systems use four to six effects, most of which are the long tube vertical rising film type. Newer systems may be designed with seven or even eight effects using falling film and forced circulation crystallization technology for high product solids.
The median age of all North American evaporator systems is 44 years. Roughly 25% of the current North American operating systems are 54 years or older. Older systems require more periodic maintenance and have a higher risk of unplanned downtime. Also, older systems have chronic issues with persistent liquor and vapor leaks, shell wall thinning, corrosion, and plugged tubes. Often these issues worsen to the point of requiring rebuild or replacement. When considering the age, technology, and lower efficiency of older systems, a major rebuild or new system may be warranted. The intent of this paper is to review the current state of black liquor evaporator systems in North America and present a basic method for determining whether a major rebuild or new installation is warranted using total life cycle cost analysis (LCCA).
