A puha (soft) és a kemény (hard) készségek munkaerőpiaci szükségessége
Authors: Horváth-Csikós Gabriella , Juhász Tímea
Published: January 2022

Összefoglaló. Jelen tanulmány célja annak vizsgálata, hogy a
jelenlegi munkaerőpiacon a puha (soft) vagy a kemény (hard) készségek jelennek
meg erősebb elvárásként a munkavállalók szerint. A kutatás eredménye rámutatott
arra, hogy egyes puha készségek (például a rugalmasság, kommunikáció,
csapatmunka) erősebb elvárásként vannak jelen a munkaerőpiacon, mint az olyan
kemény készégek, mint például a szakmai ismeret. Az eredmények azt is mutatják,
hogy a puha és a kemény készségekkel szembeni elvárások kevésbé függnek össze,
vagyis a munkavállalók szerint a munkáltatók nem rendszerszintű, egymással
szorosan kapcsolatban álló készségekként értékelik ezeket. Eredményeink arra is
rámutatnak, hogy a puha és kemény készségek önbevalláson alapuló szintje erősen
összefügg a válaszadó nemével, életkorával és iskolai végzettségével.

Summary. The aim of the present study is to examine whether soft or
hard skills are seen as the strongest requirement in the current labour market.
The results of the research showed that some soft skills (e.g. flexibility,
communication, teamwork) are almost more strongly expected than hard skills
(e.g. professional knowledge). These results basically indicate that
expectations of soft and hard skills are less interrelated and that employees
perceive employers as valuing these skills as non-systemic, closely related
skills. Our results also show that self-reported levels of soft and hard skills
are strongly correlated with gender, age and educational attainment of the
respondent.

Authors: Santos-Silva Celeste , Natário Bruno , Andrade José , Louro Rogério
Published: January 2022

The Serra de São Mamede Natural Park is a biodiversity hotspot in the broad region of Alentejo, Portugal, where the influence of the Atlantic Ocean allows for the continuity of a Eurosiberian-like forest in the heart of a Mediterranean region. The park is therefore unique among the few protected areas in Portugal. We attempt to describe the macrofungal diversity of the park for the first time. Our results reveal a rich and diverse assembly of macrofungal species (239 taxa), and in particular, mycorrhizal species (145 taxa). Furthermore, 26 taxa are newly recorded from Portugal, while 81 taxa are newly recorded from Alto Alentejo Province. Also, the majority of these newly reported taxa were recorded in mixed stands of Quercus pyrenaica Willd.—a European protected habitat of limited extent—whose importance is enhanced now the rich and diverse associated macrofungal community, as shown in our study.

Published: January 2022

To study the bearing capacity of pond ash, samples were taken from dumps of a number of power plants in the Russian Federation: Omsk TPP-4, Novocherkasskaya TPP, Serovskaya TPP, Apatitskaya TPP, producing pond of various genesis. All studied materials classified to class F according to ASTM C-618-12. At the first stage of the study, the maximum dry density of soil and the optimum moisture content were determined by the Proctor method (type B mold and type A compaction hammer), the results of which were compared with the results of determining the same parameters by the SoyuzDorNII method (using a large standard compaction device). At the second stage, the Californian bearing ratio (CBR) of all samples of pond ash in a water-unsaturated state at different densities was determined (corresponding to compaction 7, 21 and 56 by blows of a compaction hammer on a layer of pond ash in the a Proctor mold). At the third stage of the study, the deformation modulus of pond ash were determined on samples with optimal moisture content and maximum dry density of soil by the method of oedometer test. Samples were prepared with the using a large standard compaction device of the SoyuzDorNII design. At the end of the study, the results were analyzed and conclusions were drawn about the linear relationship of the parameters (optimal moisture content and maximum dry density) determined by the method of Proctor and SoyuzDorNII, the presence of a correlation between CBR and the compaction coefficient of the PA, and the absence of a statistically significant correlation ( R 2
INVESTIGATION OF THE INTERACTION OF GRILLAGE AND PILES WITH WIDENING IN THE STRIP FOUNDATION
Authors: Malyshkin A. P , Esipov A. V
Published: January 2022

The research goal is to formulate and solve the problem of distributing the external load between piles with widening and a low grillage as part of a strip foundation in a flat setting and comparing the results obtained with experimental data. The design model of Flaman (the plane problem) and Boussinesq (the spatial problem) about the force applied on the surface and Melan's solution about the force applied inside the soil half-space are taken as the initial design models. An analytical calculation method was proposed, as a result of solving the problem. This method, with sufficient accuracy for practical purposes, allows to define the bearing capacity of the foundation on piles with widening and to estimate the distribution of the load between the piles and the grillage as part of the strip foundation. The proposed approach to solving the problem of load distribution between the grillage and piles with widening is important for design of strip foundations.

Published: January 2022

Paper presents results of experimental and theoretical studies of vertically loaded large bored piles (length from 50 meters and more) performance. The analysis of O-cell load tests on vertically loaded large bored piles with 2m diameter, 55 and 65 meters length, in clay soils is carried out. According to the test results, features of an end and a shaft resistance (formation) were detected, and on this basis, a justification of necessity to calculate such piles according to the second limit state is given, taking into account the compressibility of the pile trunk. The kinemetic scheme of inclusion in the work of the soil base and the pile trunk as it is loaded with a vertical load is presented. A shown software research of piles based on pile tests on a real object. On this basis, a method for calculating the permissible settlement of a single pile and a method for determining the permissible load on the pile, at which the setting of the pile does not exceed the permissible settlement for the designed building, has been developed. An example of calculating a bored pile according to the developed method is given.
THE IMPACT OF THE FOUNDATION PIT WITH ADDITIONAL TRANSVERSE WALLS ON THE SURROUNDING BUILDING AND THE ASSESSMENT OF THE EFFECTIVENESS OF THE MEASURES UNDER CONSIDERATION

Published: January 2022

Currently, the implementation of the largest infrastructure projects of the capital continues. The development and modernization of urban transport is accompanied by a large number of deep open workings, often located in established areas of Moscow with developed buildings. Standard design solutions are not always able to provide the necessary safety of nearby buildings, so in some cases additional measures are needed. In this paper, the construction of a pit of an assembly-panel chamber with the use of protective measures in the form of additional transverse walls is considered. To evaluate the effectiveness, compare the results and consider the features of this solution, a series of calculations were carried out in spatial and flat formulation. Within the framework of a two-dimensional task, a methodology for accounting for these measures was proposed, showing close efficiency values in relation to the 3D model. The effects of concrete creep were also considered by using the initial modulus of elasticity Eb and the modulus of deformation Eb,τ. According to the results of calculations of the spatial scheme, the introduction of additional walls reduced the horizontal movements of the fence by 29 %, additional precipitation of foundations by 55 %, creep accounting, in turn, increased the horizontal movements of the SVG by 37 %, but reduced the value of the bending moment by 30 %. However, the actual values of additional deformations of the foundations still turned out to be less than predicted. Thus, it is worth noting that this type of measures is an effective way of passive protection of the surrounding development, implemented at the stage of design decisions, the full effect of which is clearly reflected in the results of the calculation of spatial models and in-situ monitoring data.
Chromosome-condensed G1 phase yeast cells are tolerant to desiccation stress
Authors: Zhang Zhaojie , Zhang Gracie R.
Published: January 2022

The budding yeast Saccharomyces cerevisiae is capable of surviving extreme water loss for a long time. However, less is known about the mechanism of its desiccation tolerance. In this study, we revealed that in an exponential culture, all desiccation tolerant yeast cells were in G1 phase and had condensed chromosomes. These cells share certain features of stationary G0 cells, such as low metabolic level. They were also replicatively young, compared to the desiccation sensitive G1 cells. A similar percentage of chromosome-condensed cells were observed in stationary phase but the condensation level was much higher than that of the log-phase cells. These chromosome-condensed stationary cells were also tolerant to desiccation. However, the majority of the desiccation tolerant cells in stationary phase do not have condensed chromosomes. We speculate that the log-phase cells with condensed chromosome might be a unique feature developed through evolution to survive unpredicted sudden changes of the environment.
Renovationists and the Soviet government in 1923 in the coverage of the Exarch of Russian Catholics
Authors: Beglov A. L.
Published: January 2022

The publication introduces into scientific circulation three documents of 1923, identified in the archive of the head of the Papal Mission to help the hungry in Russia, fr. Edmund Walsh, stored in the library of Georgetown University (USA). The central document of the published collection is a letter from the Catholic priest Leonid Fedorov, who in 1921-1935 was the head of the Apostolic Exarchate of Catholics of the Byzantine Rite in Russia. The example of the policy in relation to the Renovationist movement is used in the letter to characterize the policy of the Soviet government in relation to religion. Fedorov emphasizes the falsity of the authorities’ assurances about freedom of conscience in the USSR and concludes that the policy is aimed at eradicating all religion. He backs up his opinion with a letter from one of the leaders of the renovationism Mitr. Antonin (Granovsky) with complaints about the tax policy of the authorities. The documents are published for the first time in the original language and translated into Russian.

ABSTRACT Introduction We evaluated the clinical and radiological outcomes of capitellar fractures treated with modified screw insertion (inserting the first fixation screw anteroposteriorly and the second screw posteroanteriorly), a technique that can be applied with a minimally invasive lateral elbow approach. Materials and Methods Twenty-one isolated capitellum fractures that were surgically treated were included in the study. Fixation was achieved with two headless cannulated compression screws placed in anteroposterior and posteroanterior order using the modified lateral elbow approach. The Broberg-Morrey rating system was used to assess the post-operative functional status of the patients. Results According to the Broberg-Morrey criteria, the mean score was 92.7 (77-100) and 13 cases had excellent, 7 had good, and 1 had fair results. None of the patients developed avascular necrosis or heterotopic ossification. According to the Broberg-Morrey arthrosis score, two cases had Grade 1 and one had Grade 2 arthrosis. One patient had a superficial wound site infection that was treated with antibiotics, and in one case a 60° extension loss was observed in the elbow. Conclusion Treatment of isolated capitellar fractures with 2 headless screws placed anteroposteriorly and posteroanteriorly can provide stable fixation and is less traumatic for the elbow joint.

ABSTRACT Introduction. Osteitis pubis is a common inflammatory disease of the pubic symphysis, defined as a chronic pain syndrome caused by repetitive microtrauma. Since adaptative changes are necessary in the pelvis to adjust the equilibrium of the myotendinous structures, the aim of this study was to evaluate the correlation between pelvic incidence and osteitis pubis among professional soccer players. Materials and Methods. An observational, cross-sectional study was performed with professional soccer players from five teams during pre-season. Athletes with previous congenital pelvic abnormalities or a history of surgery were excluded. Radiographs of the pelvis were analyzed by two radiologists and assessed for findings consistent with osteitis pubis, and the following parameters were measured: pelvic incidence (PI), sacral inclination (SI), and pelvic version (PV). Results. A total of 107 subjects were included in the study, with a mean age of 25.6 ± 3.1 years. Findings compatible with osteitis pubis were present in 74.8% of the subjects (80/107). There was no statistical correlation between osteitis pubis and PI (52.3°±12.7° vs. 48.4°±10.8°; p=0.156), SI (43.1°±9.8° vs. 39.9°±10.1°; p=0.146), or PV (9.2°± 6.3° vs 8.6°± 7.5°; p=0.649). Agreement between readers was excellent (p<0.0001). Conclusion. There was no significant correlation between pelvic parameters and radiographic diagnosis of osteitis pubis.

ABSTRACT Introduction We compared the mechanical properties of two fixation techniques for the treatment of extra-articular distal third humeral fractures. Materials and Methods Two groups were created from twenty-four humeri. Group 1 was instrumented using a new, precontoured, 8-hole (3.5-mm-diameter) locking compression plate (LCP) placed anterolaterally. Group 2 was instrumented using an 8-hole (3.5-mm-diameter) precontoured posterolateral LCP plate placed on the distal humerus. Four-point bending tests and torsion tests were performed until the specimens broke. Results The four-point bending stiffness test showed that the stiffness of anterolaterally fixed humeri was significantly higher than that of posterolaterally fixed humeri (p<0.05). Torsion testing revealed that posterolateral fixation was associated with better yield strength (p<0.05), but the torsional stiffness did not differ significantly between the two plates (p> 0.05). Conclusions The anterolateral plate exhibited higher bending stiffness and torsional yield strength than the posterolateral plate. Anterolateral plate fixation can thus be used to manage extra-articular distal humeral fractures. Multiaxial locking screws ensure rigid fixation, allow early elbow motion without olecranon fossa impingement, and prevent iatrogenic injury of the triceps muscle.

ABSTRACT Introduction This study aims to investigate the clinical-functional results of a new surgical technique, Percutaneous Endoscopic Lumbar Interbody Fusion (PELIF), in patients with a clinical diagnosis of low back or sciatic pain and segmental instability who were submitted to surgery using this technique assisted by the attending physician. Materials and methods Patients completed a consent form and were clinically and radiographically re-assessed by independent evaluators using the visual analog scale (VAS) for pain, the Oswestry Disability Index (ODI), and the SF-36 Quality of Life Score in the pre- and postoperative periods. Their medical records were also reviewed for surgical time, length of hospital stay, need for blood transfusion, return to work, and radiographic fusion evaluation. Results In the group of 19 patients with 33 levels operated, VAS and ODI decreased from 10.0 and 64% to 2.0 and 28%, respectively. The SF-36 showed significantly higher scores in 5 of its 7 domains at the end of the follow-up as compared to the preoperative period scores. Only 1 case of pseudoarthrosis was diagnosed radiographically. Conclusions Percutaneous Endoscopic Lumbar Interbody Fusion (PELIF) has been shown to be a safe and efficient technique for the treatment of patients with segmental instability associated with low back or sciatic pain.

ABSTRACT Introduction Fractures of the distal third of the forearm are common in the pediatric population. Conservative treatment of an ipsilateral fracture of the distal ulna metaphysis is one of the risk factors for loss of reduction. Percutaneous fixation of the fracture with K-wires is recommended. This study aims to evaluate the outcome of percutaneous fixation of both bones performed as the primary treatment. Materials and Methods A randomized, open, prospective, clinical trial was conducted, including skeletally immature patients who underwent surgery for fractures of the distal radius and ulna. They were randomized into two groups, one with fixation only of the radius fracture and the other with fixation of both the radius and the ulna fractures, and they were followed clinically and radiologically for up to 12 weeks postoperatively. Results Sixteen children were selected. In the intraoperative period, fluoroscopy was activated for a longer time when fixing the ulna (p = 0.011) and the surgical time was longer in this group (p = 0.014). In the postoperative evaluations, the group whose surgery involved the fixation of both bones had a lower postoperative pain score (p <0.001) and less time away from school (p <0.001). Conclusions In this study, postoperative pain and absence from school were both less when fixation of the radius and ulna was performed. Evidence Level II; Randomized Controlled Study.

Command and Control of Multi-domain Operations
Authors: Mező András
Published: January 2022

The command and control system of NATO's joint operations requires large scale command posts, large numbers of stuff, and spacious, big sized infrastructure that even to operate are cumbersome, but also are an extremely attractive target for the adversary due to its extensive infrastructure and large supporting staff. The Alliance will face unpredictable challenges in the future, extending beyond traditional operational domains such as space and cyberspace. On top of that, the operations will extent to the full spectrum of operations, that is from low-intensity peacetime military engagement to high-intensity war conflict. These trends will further increase the size of the command posts. This paper presents the requirements for future operational staffs and command posts, while trying to find answers to emerging challenges.
The strategic role of the former railway bridge at Dunaföldvár
Authors: Tóth Bence , Lévai Zsolt
Published: January 2022

With the suspension of the investment into the V0 railway line, the issue of the railway lines bypassing Budapest came to the front again. As an alternative of building a new railway line, the development of existing ones or the rebuilding of lines that have been in operation in the past should be examined. In this paper, we deal with a previously operated, now discontinued Danube crossing facility, the Solt–Dunaföldvár railway bridge. Although this crossing was of minor importance during its operation, it is worth examining the role it can play should it be rebuilt with parameters required for a TEN-T railway line. According to our graph-theory based calculations, such a bridge cannot only be part of the only reasonable detour if the Southern Railway Bridge in Budapest is disrupted but can also be a facility disencumbering it under normal operational conditions.
Incidence of radius shortening following intramedullary nail fixation for gunshot fractures: a retrospective radiological audit
Authors: Abramson Michael , Maqungo Sithombo , Dey Roopam , Laubscher Maritz
Published: January 2022

ABSTRACT BACKGROUND: Intramedullary nail fixation is an option to manage highly comminuted fractures of the radius shaft resulting from gunshot wounds. However, complications including nail migration and malunion are well documented. We have noticed some patients presenting to our clinic with radiological shortening following nail fixation. This may result in chronic pain, reduced pronation and supination, poor grip strength and early onset arthrosis. This study aimed to quantify the incidence of radiological shortening following fixation of isolated gunshot wound (GSW) fractures of the radius with an intramedullary nail. Our secondary objectives were to identify if length of the zone of comminution and anatomical location of the fractures were risk factors for shortening, and to assess whether shortening was a result of surgical error, or whether shortening occurred over time. METHODS: We performed a retrospective review of all (n = 40) isolated radius nails performed between January 2012 and January 2019. Two doctors assessed the latest anterior-posterior forearm X-ray of every patient, using the rule of perpendiculars to calculate ulnar variance (UV). Shortening was defined as a UV > 5.0 mm. If the radius was deemed shortened by consensus, then the immediate postoperative X-ray was also assessed to gauge when shortening occurred. Anatomical location in thirds and length of comminution (mm) were also assessed. RESULTS: Forty patients with a mean age of 32 years (range 15-59) were included. Twelve patients' radiuses were assessed as radiologically short. All 12 were deemed to have been fixed short. One case shortened further over time. We found the incidence of shortening being dependent on the fracture location (p = 0.03), with the fractures occurring in the middle third of the arm shortening more. The measured zone of comminution between the shortened and non-shortened groups was not found to be statistically significant (p = 0.55). CONCLUSION: The radius nail remains useful to manage comminuted radius shaft fractures following GSW. Meticulous technique is needed to avoid radiological shortening, seen in 30% of our series. This can lead to chronic pain, reduced grip strength and early onset arthrosis. We found no evidence that shortening develops over time. We found that the incidence of shortening is dependent on fracture position but did not And any causative relationship between length of the zone of fracture comminution and shortening.

Published: January 2022

ABSTRACT Equitable access to life-giving occupational participation lies at the centre of occupational therapy s mission and is pivotal to development in South Africa. Contextually responsive education, research, policy and practice are a means of achieving this. This, however, necessitates knowing how to be or become contextually responsive as individuals and as a profession. It also necessitates partnership between our 'feet on the ground' practitioners and 'head in the cloud' academics - a productive collision of reality and possibility. This commentary explores what it means to be contextually responsive, whether it's possible for practitioners and scholars to pursue this together, and poses recommendations for finding each other in the journey of becoming.

Quality of life (QOL) is essential for sport and academic performance, personal satisfaction, and general health. This study aimed to examine the QOL of female athletes at the NCAA Division I, NCAA Division II, NJCAA Division II, and student club sport levels. This cross-sectional study included N= 159 female athletes to complete a personal demographics and World Health Organization Quality of Life- Brief (WHOQOL-BREF) assessment. The primary QOL, including physical, mental, social relationships, and environmental health domains and total scores, were analyzed using Kruskal-Wallis tests. NCAA DI had a higher total QOL score than NJCAA (p< 0.001) and NCAA DII and NJCAA athletes (p< 0.05). Likewise, NCAA DI had higher physical health scores than NCAA DII and NJCAA DII athletes, and club athletes higher than NCAA DII, p< 0.001. Lower mental health scores were found for NJCAA and club athletes compared to NCAA I, p< 0.01, and NCAA II, p= 0.02, athletes. NJCAA athletes had lower environmental health than NCAA DI and DII sports athletes, p= 0.05. No differences were found for the social relationships domain, p= 0.61. In conclusion, collegiate female athletes’ QOL warrants improved wellness services, especially at the NJCAA level.

Academic Self Efficacy and Dispositional Hope as Predictors of Academic Procrastination: The Mediating Effect of Academic Intrinsic Motivation
Authors: BOZGÜN Kayhan , BAYTEMİR Kemal
Published: January 2022

This study aims at determining the mediating effect of academic intrinsic motivation on the relationship between both students’ academic self-efficacy and dispositional hope levels to their academic procrastination habits. The data were collected from a sample of 252 college students, 69 males (27.4%) and 183 females (72.6%), aged between 18 and 33 (X = 20.55; Sd =1.52) studying at a state university located in the Central Black Sea region of Turkey using a correlational survey model. Academic Self Efficacy Scale, Dispositional Hope Scale, Academic Intrinsic Motivation Scale, and Aitken Academic Procrastination Scale were used as data collection tools. Descriptive statistics of the socio-demographic characteristics were presented, and Pearson correlation analysis was conducted to determine the correlations between variables by using SPSS statistical package programme. The hypothesis measurement model and the mediating effect were examined by Structural Equation Modeling (SEM) by using LISREL statistical software. The obtained results showed that significant (low and moderate) relationships exist between variables and the model tested in the study yielded acceptable and good fit index values. A complete mediating effect of academic intrinsic motivation on the relationship between both academic self-efficacy and dispositional hope with academic procrastination was determined. The findings were discussed, and some recommendations were made.

Published: January 2022

Due to ongoing research work, a prototype test rig for testing high speed motors/generators has been developed. Its design is quite unique as the two high speed machines share a single shaft with no support bearings between them. A very high maximum operating speed, up
to 80,000 rpm, was required. Because of the need to minimise vibration during operation at very high rotational speeds, rolling bearings were used. To eliminate the influence of higher harmonics of supply voltage and current on the formation of torque oscillations on the shaft and excessive losses in the form of heat, a voltage source inverter with high switching silicon carbide (SiC) power transistors characterizing high precision of the output voltage generation with a fundamental harmonic frequency of several kilohertz has been used. During the first start-ups, it turned out that the system was not stable, and a failure occurred. The paper presents the consequences that may arise when a machine operating at a speed of about 70,000 rpm fails. The article contains pictures of a generator failure that occurred at a high rotational speed.

Authors: Birth Torsten , Jentsch Sebastian , Hayen Sophia , Scheffler Marcel
Published: January 2022

Der Aufbau einer Wasserstoffwirtschaft bietet die Chance klima- und energiepolitische Ziele zu erreichen. Die Umsetzung und Realisierung mittels Power-to-Gas(PtG)-Anlagen sind von Wechselwirkungen zwischen den erforderlichen Ressourcen und der Energiewirtschaft abhängig. Insbesondere die Ressource Wasser wird durch die Realisierung mittels Elektrolyse beeinflusst. In der vorliegenden Studie wird der Ausbau von PtG-Anlagen in Mitteldeutschland dargestellt, der Wasserbedarf analysiert und mit der regionalen Wasserverfügbarkeit ins Verhältnis gesetzt. Das Aufkommen von Wasserstress in Mitteldeutschland durch PtG-Anlagen ist über 2030 hinaus kaum ersichtlich, jedoch zeichnet sich die Verstärkung bereits lokal vorhandener Wasserdefizite ab. Als positive Entwicklung für das Wasserdargebot wurde der Braunkohleausstieg identifiziert. Gleichwohl ist die Modellregion von Trockenheit betroffen, weshalb ein nachhaltiges Wassermanagement unerlässlich ist.

Elastic equilibrium of shallow toroidal shell loaded by internal pressure and containing the cross-cutting crack located along equator or throat of the shell has been studied in the two-dimensional formulation. The shell is reinforced by coating on one of the face surfaces. The crack in the shell with a flexible coating is simulated by a cuts with eccentrically hinge joint edges. The boundary problem for equations of classical shell theory with interrelated conditions of tension and bending along the cutting line is formulated within the framework of such model. Singular integral equation for the unknown jump of normal displacement on the crack edges has been elaborated. Based on asymptotical solutions of integral equation obtained using the small parameter method forces and moments intensity factors in the vicinity of the defect tips are defined. Their dependences of on the parameters of shell curvature and form parameter are investigated. It is established that the reinforcement of the shell leads to a decrease in the force intensity factor and to the appearance of a non-zero moment intensity factor.

This study consists of two parts. First we consider an analytical approach for solving the problem of steady Stokes flow in some 3D containers with arbitrary velocities prescribed over the surfaces. The approach is based on the superposition method. First we discuss the Stokes problem solution in a finite cylinder. This is the simplest problem because the flow domain is restricted with only two families of coordinate surfaces and the edge (rim) is a smooth line. Then we discuss the analytical solution of the Stokes problem in more complicated domains, such as a circular cone, a rectangular trihedral corner and a 3D rectangular cavity. The Moffatt eddies in such domains are described. In the second part of the study we consider the laminar mixing process in the Stokes flow in a 3D container. We show that in 3D flows a much richer variety of mixing regimes is observed than in 2D flow configurations. The mixing processes in a 3D flow, containing periodic lines, possess essentially two-dimensional characteristics. In the flows, where only isolated periodic points exist, the liquid elements stretch or compress in all three directions.

Authors:   S.P. Timoshenko Institute of Mechanics NAS Ukraine, Maslov B. P.
Published: January 2022

Nonlinear hereditary creep problem of the mechanics of composites is solved within the framework of a second-order theory. The hereditary functionals are used to construct general constitutive relations. A stochastic boundary value problem for determining the stress concentration and its relaxation in metal matrix composite (PMC) is solved in Laplace-Carson image space. Shapery's correspondence principle for quasi-linear viscoelastic media is generalised on the hereditary creep problem and the method of successive approximation is used. The reduced creep functions and the stress concentration parameters are determined. Examples are given showing the importance of the mutual influence of nonlinear elastic and viscous properties of the components on stress redistribution near inclusions with possibility to predicting the long-term strength.

Published: January 2022

The dynamic nature of business marketing in various parts of the world and industries is associated with a quest to achieve or attain and retain competitive advantages. With such advantages coming in the form of increased product user bases, a majority of the firms have ended up embracing business internationalization to stretch beyond local and regional borders within which they are based. With these efforts associated with improved company performances, Wal-Mart has been unexceptional. The effort to retain a competitive advantage and superior brand image across the world has been evidenced by its recent merger with Massmart, a South African company that owns brands such as Builder’s Warehouse, Makro, and Game. It is also worth highlighting that Massmart is South Africa’s second largest distributor of consumer goods and remains the largest retailer dealing in basic foods, liquor and home improvement equipment, and general merchandise. This paper examines the merger between Wal-Mart and Massmart, focusing on issues such as the international market analysis of the retail industry, aspects of product category and demand size, and competition analysis. In so doing, resultant recommendations might give an insight into current trends in business marketing strategies that embrace mergers, as well as lay an opportunity for improvement in the Walmart-Massmart merger and others at the intra-industry and inter-industry level.
Review on Holographic Techniques for Photolithography
Authors: Mondal Dipannita
Published: January 2022

Holographic methods utilizing spatial modulators to supplant the covers in photolithographic process. PC produced 3D images got from two pictures with known measurements, reproducing a clear visible field Mask and dark prior mask. The reason for the proposal is to consider the potential outcomes of picture decrease, through a holographic based optical segment arrangement, produced by spatial modulators from a CGH (Computer-created Hologram). Comprehend the outcomes by decreasing the pictures and look at the outcomes acquired. Boundaries, for example, complexity, goal and least size of the pictures produced from the spatial modulators will be broke down so as to decide the conceivable outcomes of progress and the confinements of the procedure applied to photolithography. It is accepted that the uniform and dainty oppose film can be effectively kept on the filaments by utilizing the electro-shower covering innovation. Nonetheless, high electronic voltage and conductive surface are required with the goal that the current smaller scale structures are exposed to harm. The immediate splash covering is liberated from electronic and other harm to substrates yet it is influenced by numerous boundaries including the arrangement thickness and substrate temperature.
Mathematical Chance Constrained Framework Application
Authors: Runera Ms. Nora Zilam
Published: January 2022

Chance Constrained Programming (CCP) as one of the special parts of mathematical programming in which its application in industrial and academic fields is currently needed to cover the problem of uncertainty in making decisions. The CCP  technique is an efficient and easy tool to apply for data involved to random parameters by assuming random parameters must follow a stable normal distribution. In selection process, budget goal, making the most benefits, and achieving minimum travel are considered as a random parameter and solved by using CCP. Goal Programming (GP) model, will be used to model the rail system transportation project selection process, because allocating resources into all projects at the same time requires multi-criteria decision making techniques.
The Reduced Gradient Method Application
Authors: Basaligheh Prof. Parvaneh
Published: January 2022

This study proposes a decomposition method through which they can be a successful solution to multi-stage stochastic nonlinear programs. The proposed method entails the scenario analysis method. The proposed method also performs its role via search direction generation in such a way that sets of quadratic programming sub-issues are solved in a parallel way, especially when the size is significant lower, compared to the case involving original problems at the respective iterations. Relative to the dual multiplier derivation, which focuses on non-anticipativity constraints, the proposed system advocates for the introduction of generalized reduced gradient approaches.
Time-To-Collision Models for Single-File Pedestrian Motion
Authors: Cordes Jakob , Chraibi Mohcine , Tordeux Antoine , Schadschneider Andreas
Published: January 2022

We apply the concept of time-to-collision (TTC) to the modeling of pedestrian dynamics. The TTC combines the spatial distances with the velocities to quantify the 'distance' to a collision. Therefore, it is a promising candidate for modeling the interactions between pedestrians. Empirical studies also indicate that the interaction between pedestrians can be described by the TTC: While the pair distribution of the distances, i.e. the probability of two pedestrians to have a certain spatial distance, was found to strongly depend on the relative velocity, the TTC accurately parametrizes its pair distribution. However, there are still few pedestrian models that use the TTC. After giving a general definition of the TTC, we present the widely used approximations for its calculation, especially in a one-dimensional setting. Combined with a desired time-gap, these give rise to different models, namely an Optimal-Velocity model and a new Time-to-Collision model. The TTC model exhibits, however, generic inconsistencies which are related to the estimates we use to approximate the speed of the predecessor. The estimates have a large impact on the dynamics and must therefore be interpreted as reflecting the pedestrians behavior, i.e. as anticipation strategies. We propose new estimates for the predecessor's speed. These give rise to a rich family of models based on the TTC which are analyzed by means of linear stability analysis and simulations.

Published: January 2022

The study presents the history of asexuality a sequence of epochs conditioned by the control, regulation of non-normative practices and gender order. The author examines asexuality in the context of pathologization and normalization, which resemble the history of homo- and bisexuality. The result of the pathologization of asexuality was the construction of identity as a basis that deprives doctors of the right to pathologize it.
