Authors: Arslan Serdar , Dinç Engin
Published: May 2021

BACKGROUND: The Functional Movement Screen (FMS) is a clinical assessment tool used to determine musculoskeletal dysfunctions and asymmetries in athletes. OBJECTIVE: The aim of this study was to investigate whether FMS scores differed between elite youth male soccer players with low body fat percentage and those with normal body fat percentage and between those with and without a history of soccer injury. METHODS: Fifty-three elite youth male soccer players were included in the study. The participants’ injury histories were recorded, followed by body composition assessment and FMS tests. The participants were grouped according to body fat percentage and injury history for data analysis. RESULTS: The mean age, weight and height of the participants were 17.11 ± 0.91 years, 68.78 ± 7.41 kg and 1.77 ± 0.57 meters, respectively. Comparisons of the groups according to body fat percentage and injury history revealed no differences in FMS scores (p> 0.05). CONCLUSION: Lower body fat percentage did not confer an advantage or disadvantage to elite youth male soccer players in terms of FMS scores FMS scores provide limited information to predict injuries in elite youth male players.

An adaptive frequency – Voltage control model for extracorporeal supporting flow regulation in an extracorporeal membrane oxygenation system
Authors: Lin Chia-Hung , Kan Chung-Dann , Chen Wei-Ling , Mai Yi-Chen , Chen Ying-Shin
Published: May 2021

Extracorporeal membrane oxygenation (ECMO) is employed to treat critical patients for one to a few days of life support in intensive care units. Venovenous (VV) and venoarterial (VA) ECMO configurations are the most commonly used rescue strategies for temporary cardiac and respiratory function support. However, both ECMO modes sometimes cannot meet a patient’s demands because of (a) less oxygenated blood in either the upper body or lower body, or (b) a deterioration in the patient’s hemodynamic status. Veno-Venoarterial (VVA) ECMO is an upgraded system that provides sufficiently oxygenated blood to the systemic and pulmonary circulation systems. Drainage cannulas and gas flow exchanges are determined to provide the maximum drainage blood flow required by the patient through a servo-regulator that adjusts the motor speed. A generalized regression neural network (GRNN) based estimator is created to automatically estimate the desired pump speed and then provide sufficient drainage flow for temporary life support. To achieve stability flow in an ECMO circuit, a bisection approach algorithm (BAA) is employed to improve the performance of transient responses in step controls and steady state controls. Experimental studies are used to validate the proposed model and it is compared with conventional controllers to indicate good performance in clinical VVA ECMO applications.

Authors: Chekani Farid , Pike James , Jones Eddie , Husbands Joseph , Khandker Rezaul K.
Published: May 2021

Background: Dementia is commonly accompanied by neurobehavioral symptoms; however, the relationship between such symptoms and health-related outcomes is unclear. Objective: To investigate the impact of specific neurobehavioral symptoms in dementia on healthcare resource use (HCRU), patient quality of life (QoL), and caregiver burden. Methods: Data were taken from the 2015/16 Adelphi Real World Dementia Disease Specific Programme™, a point-in-time survey of physicians and their consulting dementia patients. Multiple regression analyses were used to examine associations between patient symptom groups and health-related outcomes. Results: Each patient symptom group of interest (patients with agitation/aggression and related symptoms [AARS] with psychosis, patients with AARS without psychosis, and patients with other behavioral symptoms) had a positive association with HCRU variables (i.e., HCRU was greater), a negative association with proxy measures of patient QoL (i.e., QoL was decreased), and a positive association with caregiver burden (i.e., burden was greater) compared with patients with no behavioral symptoms (control group). The magnitude of effect was generally greatest in patients with AARS with psychosis. Regression analysis covariates that were found to be most often significantly related to the outcomes were dementia severity and the patients’ living situation (i.e., whether they were in nursing homes or living in the community). Conclusion: Combinations of behavioral symptoms, particularly involving AARS plus psychosis, may have a detrimental impact on health-related outcomes such as HCRU, patient QoL, and caregiver burden in dementia. Our results have implications for intervention development in patients who report clusters of symptoms and caregivers, and for identifying at-risk individuals.

Authors: Li Lin
Published: May 2021

With the development of the electric power industry, the technical level of automatic testing equipment for the reliability of electrical component circuit breakers in the transmission and distribution network is getting higher and higher. The stability and accuracy of the test power supply are the basis for ensuring the pass rate of the test product. Most of the electrical testing and testing equipment has defects such as inaccurate power supply current regulation, low power, and low level of intelligence, which are difficult to meet the testing requirements. Based on the theory of a closed-loop control system, this paper adopts embedded system design technology to realize a high-current, high-power, high-stability digital constant current source system for line detection. This paper studies the rule-based intelligent anti-jamming decision engine design and system anti-jamming performance analysis of NC-OFDM system. We give the design of an intelligent anti-jamming decision engine based on rule-based decision-making, and focus on two intelligent anti-jamming decision-making algorithms: Adaptive Modulation and Coding (AMC) algorithm based on signal-to-noise ratio difference and packet error rate and Adaptive Sub-Band Selection (ASBS) algorithm. Experimental test results show that the output current range is 200 mA to 2000 mA, the system has realized a microstep adjustment of±5 mA, and the absolute error of current measurement is less than 0.3%+4 mA. The system is stable and reliable, and has high practical value in the field of high precision and low power.

Authors: Antropov A. P. , Zaytsev N. K. , Ryabkov Ye. D. , Yashtulov N. A. , Mudrakova P. N.
Published: May 2021

Objectives. Catalytically active materials are required in different chemical engineering processes. This makes the development of new materials with high efficiency and original ways in which to obtain them of significant interest. The present work investigates the synthesis of catalytically active material including electrode materials, as well as their improved efficiency due to the nanodecoration of their surface.

Methods. An aluminum folio was nanoperforated (nanoscalloped) by high-voltage anodization in an acidic medium. The effective electrode material was obtained as a metallic nickel replica rather than an oxide layer of the product. To study the surface state of aluminum obtained in this manner, a scanning electron microscope (Hitachi-SU8200) was used. The elementary composition of the aluminum was determined by back-scattered X-ray irradiation.

Results. The nickel replica obtained in the above-described process exceeded the catalytic activity estimated by methanol oxidation of the unprocessed nickel 70–150 times.

Conclusions. The present paper demonstrates the potential of creating effective catalytically active nanopillar materials using the metallic rather than metal-oxide part of a layer of anodized aluminum as a matrix template.
Dielectric properties of the system: 4-n-pentyloxybenzoic acid– N-(4-n-butyloxybenzylidene)-4᾽-methylaniline
Authors: Syrbu S. A. , Fedorov M. S. , Lapykina E. A. , Novikov V. V.
Published: May 2021

Objectives. Our aim was to study the dielectric properties of the 4-n-pentyloxybenzoic acid– N-(4-n-butyloxybenzylidene)-4’-methylaniline system and reveal how different concentrations of N-(4-n-butyloxybenzylidene)-4’-methylaniline additives affect the dielectric properties of 4-n-pentyloxybenzoic acid.

Methods. System properties were investigated using polarization thermomicroscopy and dielcometry.

Results. We found that dielectric anisotropy changes its sign from positive to negative at the transition temperature of the high-temperature nematic subphase to the low-temperature one. The anisotropy of the dielectric constant of N-4-n-butoxybenzylidene-4’-methylaniline has a positive value and increases as to the system approaches the crystalline phase. The crystal structure of the 4-n-pentyloxybenzoic acid contains dimers formed by two independent molecules due to a pair of hydrogen bonds. The crystal structure of N-(4-n-butoxybenzylidene)-4’-methylaniline contains associates formed by orientational interactions of two independent molecules. 4-n-Pentyloxybenzoic acid dimers (270 nm) and associates of N-4-n-butoxybenzylidene-4’- methylaniline (250 nm) proved to have approximately the identical length. Considering the close length values of the structural units of both compounds and the dielectric anisotropy sign, we assume that the N-4-n-butoxybenzylidene-4’-methylaniline associates are incorporated into the supramolecular structure of the 4-n-pentyloxybenzoic acid. The specific electrical conductivity of the compounds under study lies between 10−7 and 10−12 S∙cm−1. The relationship between the specific electrical conductivity anisotropy and the system composition in the nematic phase at the identical reduced temperature, obtained between 100 and 1000 Hz is symbatic. However, the electrical conductivity anisotropy values of the system obtained at 1000 Hz are lower compared to those obtained at 100 Hz. At N-(4-n-butoxybenzylidene)-4’-methylaniline concentrations between 30 and 60 mol %, the electrical conductivity anisotropy values are higher than those of the individual component.

Conclusions. A change in the sign of the dielectric constant anisotropy of the 4-n-pentyloxybenzoic acid during nematic subphase transitions was established. We showed that the system has the highest dielectric constant anisotropy value when components have an equal number of moles. Highest electrical conductivity anisotropy values are observed when the concentration of the N-4-n-butoxybenzylidene-4᾽-methylaniline system lies between 30 and 60 mol %.

Authors: Volkova O. S. , Chudinov A. V. , Lapa S. A.
Published: May 2021

Objectives. This study investigated the substrate properties of the modified derivatives of triphosphates of purine and pyrimidine deoxynucleosides (5-propynyl-2’-deoxyuridine-5’-triphosphate, 5-propynyl2’-deoxycytidine-5’-triphosphate, 5-methyl-2’-deoxycytidine-5’-triphosphate, and N6-methyl-2’-deoxyadenosine-5’-triphosphate) during their simultaneous incorporation in enzymatic reactions (polymerase chain and primer extension reactions).

Methods. The real-time polymerase chain and primer extension reactions were used to study the substrate efficiency of modified deoxynucleotide triphosphates. Various pairwise combinations of modified derivatives were used; specially designed synthetic DNA fragments and libraries for the Systematic Evolution of Ligands by Exponential Enrichment technology were used as templates. Reactions were conducted using DNA polymerases: Taq, Vent (exo-), DeepVent (exo-), and KOD XL.

Results. In each case, a pair of compounds (modified dUTP + dCTP, dUTP + dATP, and dCTP + dATP) was selected to study the simultaneous incorporation into the growing DNA strand. The most effective combinations of nucleotides for simultaneous insertion were dU and dC, having 5-propynyl substitution. The Vent (exo-) DNA polymerase was found as the most effective for the modified substrates.

Conclusions. The selected compounds can be used for the enzymatic preparation of modified DNA, including aptamers with extended physicochemical properties.

Authors: Romanov S. I. , Botvinova O. A. , Timakov E. A. , Chizhova L. A. , Panov Yu. T.
Published: May 2021

Objectives. Improvement of the technology for obtaining polymer-sprayed coatings based on polycarbodiimides (polyureas) with high chemical, hydrolytic, and abrasive resistance and improved physical and mechanical properties, as well as obtainment of polyurea compositions with a lifetime of at least 5 min without loss performance characteristics (i.e., “hand-applied” polyureas) suitable for repair of coatings already in use.

Methods. The reaction rate between isocyanate and amino groups is almost a hundred times higher than that between isocyanate and hydroxyl groups, necessitating the use of special highperformance and high-pressure installations equipped with self-cleaning mixing chambers and heating of components. The following are determined from the obtained materials: strength, elongation at break according to the standard method, Taber abrasion, and Shore hardness.

Results. Three methods of slowing down the reaction are investigated: 1) the synthesis of prepolymers with the content of NCO groups from 10.5% to 18%; 2) the addition of a plasticizer into the prepolymer in the amount of 1–10 mass parts; and 3) the introduction of polyesters into the composition and radiation of the so-called “hybrid” systems. When using 14% polyesters with a molecular weight of 2000 Da, only “hybrid” systems make it possible to obtain compositions with a lifetime of more than 5 min. At the same time, the tensile strength decreases by 20%, and the abrasion increases by 40%; however, such “hybrid” systems have a higher adhesion force and are cheaper than pure polyureas, allowing them to be used as “repair” systems.

Conclusions. The developed composition and technology of applying “hybrid” systems allow for the repair of existing coatings without using specialized devices. “Manual” polyurea is easy to use and does not require special training.
Transmission coefficients of superconducting particles
Authors: Matasov A. V. , Dovmalov A. A. , Babyshkina D. M.
Published: May 2021

Objectives. There is no general theory of superconductivity capable of fully describing this phenomenon, which imposes its own difficulties in the search for new superconducting materials, as well as in the study of their properties. In particular, the electrodynamics of a superconducting system is unexplored. With the aim of a possible further description of the electrodynamics of superconductors, the temperature dependences of the energy parameters of a Cooper pair in the potential field of Abrikosov vortex were analyzed.

Methods. The basis for the obtained results of the work was the consideration of the transmission coefficient for a superconducting particle in the approximation of the Wentzel– Kramers–Brillouin method, as well as the relationship between the critical temperature and the London penetration depth and the coherence length based on the model of plasmon destruction of the superconducting state.

Results. The dependences of the lifetime of a particle in a potential well, penetration depth, frequency of impacts of a particle against a potential barrier, blurring of the energy level, transmission coefficient, and potential and kinetic energy of a particle on temperature were obtained. The characteristic values of these parameters were obtained at absolute zero for various cuprate, organic, and other superconducting materials. The dependences of the critical electric potential on temperature, as well as the London penetration depth, coherence length, and electric potential on the transmission coefficient at different temperatures were obtained. The form of the dependences qualitatively corresponds to the experimental data.

Conclusions. The results obtained can be used to construct a general theory of superconductivity, describe the electrodynamics of a superconducting state, and develop new superconductors with higher critical currents.

The objective of this study was to evaluate alternative methods to overcome dormancy in Leucena (Leucaena leucocephala) seeds. The seeds were collected from four different matrices and subsequently submitted to different treatments with mechanical scarification and immersion in water and soft drink at different times (0, 6, 24 and 48 h) at 25 ºC. A completely randomized design was used, consisting of 14 treatments composed of four replications containing 50 seeds each. The variables analyzed were: Germination at the first count (G); Normal Seedlings (PN); Hard or Dormant Seeds (SD); and Germination Speed Index (IVG). The results increased higher percentages of germination (G) in the T1 treatment (mechanical scarification) with 46.7 and 43.2% of normal seedlings (PN) with 43.2% and IVG of 41.9. However, when observing only the treatments submitted in different combinations, it was noted that the treatments T8 (Mechanical scarification and immersion in soda for 6h at 25 ºC) and T2 (Mechanical scarification and immersion in distilled water for 6h at 25 ºC) presented a germination of 44.7 and 39.7%, respectively. Thus, shorter water immersion times associated with mechanical scarification are required to obtain the highest percentage of germination and formation of normal seedlings.

Introduction: Profilin1 (PFN1) is a ubiquitously expressed protein known for its function as a regulator of actin polymerization and dynamics. A recent discovery linked mutant PFN1 to Amyotrophic Lateral Sclerosis (ALS), which is a fatal and progressive motor neuron disease. We have also demonstrated that Gly118Val mutation in PFN1 is a cause of ALS, and the formation of aggregates containing mutant PFN1 may be a mechanism for motor neuron death. Hence, we were interested in investigating the aggregation of PFN1 further and searching for co-aggregated proteins in our mouse model overexpressing mutant PFN1. Methods: We investigated protein aggregation in several tissues of transgenic and no-transgenic mice using western blotting. To further understand the neurotoxicity of mutant PFN1, we conducted a pull-down assay using an insoluble fraction of spinal cord lysates from hPFN1G118V transgenic mice. For this assay, we expressed His6-tagged PFN1WT and PFN1G118V in E. coli and purified these proteins using the Ni-NTA column. Results: In this study, we demonstrated that mutant PFN1 forms aggregate in the brain and spinal cord of hPFN1G118V mice, while WT-PFN1 remains soluble. Among these tissues, spinal cord lysates were found to have PFN1 bands at higher molecular weights recognized with anti-PFN1. Moreover, the pull-down assay using His6-PFN1G118V showed that Myelin Binding Protein (MBP) was present in the insoluble fraction. Conclusion: Our analysis of PFN1 aggregation in vivo revealed further details of mutant PFN1 aggregation and its possible complex formation with other proteins, providing new insights into the ALS mechanism.

Introduction. The philosophy of I.A. Ilyin proposes a program for the renewal of society while returning to the spiritual tradition, which seems to be relevant for modern humanitarian education. The aim of this research is to reconstruct the concept of creative doing in the I.A. Ilyin`s philosophy and to demonstrate of its application in the organization of design and research work of university`s students in the framework of humanitarian education. Materials and methods. Based on the analysis of modern research literature and works of I.A. Ilyin, theoretical and hermeneutical methods were used in this work, as well as the design and research method of organizing educational work with students. Research results. Creative doing is the creative implementation of each person's life project in real conditions. The concept of creative doing consists of four points: 1) creation of oneself; 2) building your own business; 3) building a family and raising children; 4) social and cultural creation. In the philosophical works of I.A. Ilyin, you can find this concept. By discovering spiritual reality, a person comprehends God's plan for himself, his “calling”, freely accepts it and responsibly implements it in his life. The family, created on the basis of the spiritual community of the spouses, transmits the spiritual tradition and creates a new, more creative generation. Patriotism is brought up in the family, the transition to the concepts of the Motherland, the state, domestic and world culture is carried out. The topics are named and the stages of organizing the design and research work of students are presented. Discussion and conclusions. The novelty of this research lies in the combination of theoretical (philosophical ideas of I.A. Ilyin) and practical (long-term practice of organizing students' design and research work) approaches, which allows solving educational problems within the framework of humanitarian education. The concept of creative doing allows you to combine a personal approach with domestic traditions and public good.

The present requirements of the labour market determine the need for high-quality foreign-language schooling of students of extralinguistic faculties whose competitiveness directly depends on the level of proficiency in a foreign language. In this regard, motivation is considered as one of the key factors securing success in learning a foreign language. According to the authors, alternative assessment of students’ learning progress aims to increase their motivation for learning a foreign language. The study involved 180 undergraduates of Vyatka State University majoring in Biology, Chemical technology and Ecology. The following methods were used in the course of the research: analysis, synthesis, generalisation, observation, experimental training, questioning, analysis of quantitative and qualitative results of the research. Pearson’s criterion χ2 was used for statistical processing of the results. The authors identified the following forms and methods of alternative assessment: electronic portfolio (iPortfolio), work in pairs (We Create Activity), group work project (iLearn & Teach Project), technical report (Technical report), imitation of a job interview (Mock job interview), that are approximated to real situations in the future engineers’ professional sphere and match the undergraduates’ professional interests. It was empirically proved that alternative assessment increases the students’ level of intrinsic motivation to learning a foreign language, as well as the level of motivation for mastering a profession and acquiring due knowledge. The control experiment results point at significant statistical differences between the ascertaining and the control stages of the experiment (χ2 = 17.69; at χ2crit = 5.99). The significance of the research lies in the used approach “assessment as learning” to solving the problem of increasing the undergraduates’ motivation for the study of a foreign language. This approach not only provided for the natural-science-profile students’ orientation towards professional interests and due motivation, but also made it possible to improve the learners’ communicative competence in the English language, overcome psychological barriers, develop cognitive activity and critical reasoning.

The problem and the aim of the study. A teacher of a digital school, according to the requirements of the standard of professional activity, must possess such universal qualities related to information and communication technologies, formed communicative competence, the ability to work in a team. The formation of the relevant skills within the framework of university education is complicated by a number of problems of a different nature. The authors suggest organizing a practice of designing a system of specially selected tasks to improve the training of future teachers of a digital school. Research methods. The most important idea is the acquisition of new knowledge by creation and solving tasks. The solution of the system of educational, specially designed tasks supports the implementation of the provisions of the system-activity approach to learning. The pedagogical experiment involved 120 students of specialty 44.03.01 Pedagogical education (two training profiles, bachelor's degree level), Vyatka State University, Kirov, Russia Federation. Statistical verification of the obtained results was made using Fisher's criterion (angular transformation). Results. Students of the experimental group were involved in practical activities to design their own tasks on the example of studying the theory and methods of teaching Informatics (situational-motivational; support; border): self-determination of the plot, the development directions of intensification and extensification. Statistically significant differences were revealed between the experimental and control groups in terms of the level of professional training φcrit < φemp (1.64 < 2.558). In conclusion, the authors generalized the features of the organization of practical activity for the development of a system of own tasks for a digital school: the choice of the first task, the use of information sources of various nature, learning with and without a computer, group discussion of a result, resolving contradictions, "ignorance–knowledge–understanding–skill–proficiency", work in conditions of uncertainty, etc.

The actualisation of foreign language teaching content for future bachelors in the training profile 43.03.02 Tourism, to be implemented in accordance with the requirements of the educational and professional standards, is one of the main factors in the formation of universal competencies of future bachelors, securing their competitiveness in the labour market. Materials and methods. The methodological basis of the research is represented by the competence-based and professionally oriented approaches to teaching a foreign language. The key research methods included the analysis of scientific essays of Russian and foreign scientists on the stated problem and the experimental research carried out on the basis of Bunin Yelets State University (Russian Federation) with the participation of 30 undergraduate students of the 1st and 2nd years of study. Results. In the course of the research, the original foreign-language curriculum for the students of the above-cited training profile was developed and tested. A number of supplements to the traditional content of foreign-language teaching programme are presented, proceeding from the basic requirements of the modern educational and professional standards. The comparative analysis of the data obtained before and after the training revealed a significant dynamics in the formation of universal competencies of the future bachelor in the experimental group (44.7% and 83.3%, respectively), and moderate dynamics in the control group (43% and 69.3%, respectively), since temp= 3.05 is greater than the critical tcrit= 2.14 at the significance level of 0.05. Conclusions. The obtained research results confirm the hypothesis on the practicality of forming universal competencies of future bachelors in the sphere of tourism, in the course of foreign language teaching under the advanced programme including the content modules in accordance with the areas (spheres) of professional activity and the requirements of the educational and professional standards.
