Published: July 2021

The possibilities of the LOGOS software package for calculating seismic vibrations of buried structures, considering the contact interaction with the ground and the gravity field, are investigated and expanded. To reduce computational costs, the LOGOS software package includes a method for modeling non-reflective boundary conditions that was developed earlier and implemented in the “Dynamics-2” software package, which allows reducing the size of the computational domain. The results of numerical simulation in the LOGOS of shear wave propagation in an elastic bounded subdomain of a continuous medium are presented, demonstrating the effectiveness of non-reflecting boundary conditions for a three-dimensional formulation. The dynamic relaxation technique used in the dynamic strength module of the LOGOS software package for calculating the initial static stresses from the action of the gravity field with the subsequent solution of the non-stationary problem is investigated. Numerical estimates of the expected accuracy of the dynamic solution are obtained, depending on the specified accuracy of the static calculation. Thus, the relative error in the change in kinetic energy when using the dynamic relaxation algorithm 10–4 gives a relative error of 10–3 in velocities and 10–2 in stresses, reducing the specified calculation error by 2 orders of magnitude reduces the relative error in calculating velocities by 3 times, stresses – by 5 times. The calculation of the initial stress-strain state of the building-ground system from the action of the gravity field is compared using the dynamic relaxation procedure and using the stationing procedure implemented in the “Dynamics-2” software package. In all problems in the three-dimensional formulation, 8-node hexahedra with one-point integration are used, in the two-dimensional formulation – equivalent 4-node finite elements, for the integration of the defining system of equations, an explicit “cross” scheme is used. Between the subdomains, variants of contact with gluing and contact with friction are implemented. The capabilities of LOGOS for conducting multiprocessor calculations allowed us to make estimates of the convergence of the problem under consideration based on a series of computational experiments.

An investigation was made of acoustic emission signals during uniaxial tensile testing of flat specimens of steel 20 used for parts of welded structures with a large volume of welding, as well as pipelines, collectors and other parts operating at temperatures from –40 to 450 °C under pressure. Tensile testing with simultaneous registration of acoustic emission was carried out on a universal testing machine manufactured by Tinius OIlsen Ltd, model H100KU, at a movement speed of the active gripper of 0.05 meters per minute. Registration of AE signals was carried out using wideband GT350 sensors from GlobalTest and an analog-to-digital converter NationalInstruments 6363X with subsequent storage of the registration results in the form of a time series in the computer memory. A comparative analysis of the amplitude distribution of the AE signal for the area of the yield area and the area of destruction was carried out according to the value of information entropy, fractal dimension, and self-organization parameter. It was found that the parameter of self-organization of the amplitude distribution of the signal is the most informative in describing the processes associated with acoustic emission. As additional information, it is advisable to use data on the structure of the self-organization parameter. The results obtained indicate the possibility of using the statistical model of the Dirichlet distribution as a model of processes associated with the appearance of acoustic emission signals from sources of incipient and developing defects during routine tests of products made of structural carbon high-quality steels with a pearlite-ferrite structure.

The paper presents a version of the model and modeling algorithms for FE-modeling corrosion cracking processes in structural elements loaded by pressure and exposed to aggressive corrosion media. To assess the effectiveness of the present models and algorithms, the failure process of a thin-walled tubular specimen partly submerged into a chlorine-containing liquid and loaded by axial tension is numerically modeled.
INSTABILITY IN A DISLOCATION ENSEMBLE AT PLASTIC DEFORMATION IN METALS
Authors: Sarafanov G.F.
Published: July 2021

A problem related to the development of instability of a homogeneous state in an ensemble of screw dislocations under plastic deformation of metals is considered . The study of the development of instability and structure formation in the dislocation ensemble is carried out on the basis of the method developed for charged particles in plasma and associated with the correlation interaction of electrons and positively charged ions. Accordingly, the screw dislocation ensemble is represented as a system of dislocations with an opposite Burgers vector, i.e., as a plasma-like medium with opposite dislocation charges. The total dislocation charge of the dislocation ensemble is equal to zero due to the law of conservation of the Burgers vector. In this situation, the elastic field of dislocations is “cut off”. The stress field of a single dislocation is shielded by a uniformly distributed dislocation “background” and is characterized by a certain effective potential. It is found that at long distances it decreases exponentially. Therefore, the value in the argument of the falling potential can be considered as the radius of screening of the elastic field of dislocations. It is shown that the screening radius is equal to the correlation radius, which makes it possible to construct a two-particle correlation function and find the energy of the correlation interaction of dislocations. A system of kinetic equations for a dislocation ensemble is formulated, taking into account the elastic and correlation interaction of dislocations, as well as the processes of their generation and annihilation. The criterion of instability of the homogeneous distribution of dislocations for the formulated system of equations is established. The instability criterion is met under the condition that the dislocation density exceeds a certain critical value that depends on the square of the flow stress and material constants (such as the Burgers vector modulus and shear modulus, as well as indirectly, the packing defect energy). In the framework of linear analysis, it is shown that when one system of sliding screw dislocations is taken into account, a one – dimensional periodic dislocation dissipative structure is formed at the moment of instability occurrence, and when multiple sliding is taken into account, solutions appear in the form of various variants of polyhedral lattices (cellular structures). It is established that the characteristic size of the cellular structure coincides with the experimental dependence both qualitatively and quantitatively ( the cell size is proportional to the square root of the dislocation density, and the proportionality coefficient is about ten). It is shown that the origin of spatially inhomogeneous dislocation structures, based on correlation instability, depends mainly on the features of the elastic interaction of dislocations and is not critical to the choice of the mechanisms of their kinetics (i.e., the mechanisms of generation, annihilation, and runoff of dislocations).

Intensively operated modern technology requires the use of high-strength fasteners. The article presents the results of studies of the structure and physical and mechanical properties of the material of fastening elements (threaded hardware) in order to determine the causes of their destruction during operation. The fractographic analysis of fractures of fractured bolts revealed pronounced centers of crack initiation with traces of delayed brittle fracture, which is typical for high-strength hardware that are under high load for a long time, close to the yield point. Mechanical tests of the studied fastening elements showed increased values of ultimate strength. The performed relaxation tests of the material of broken bolts also revealed an increased value of the microplasticity limit, which is responsible for the onset of plastic deformation processes in microvolumes of the material, and for the material of whole hardware, the value of the limit is included in the permissible interval. At the same time, the average hardness of the material of all products meets the regulatory requirements. The maximum spread of hardness 70 HB is fixed on the destroyed bolt. Using the experimental values of microhardness, theoretical estimates of the coefficient of plasticity, which characterize the ability of a material to perceive elastic and plastic deformations, were carried out. To ensure a sufficient level of ductility of a long-term working metal material, the ductility coefficient must be at least 0.8. The average value of the hardness of the material of the fastening elements satisfies this criterion for assessing ductility. According to the results of a step-by-step analysis of the microstructure of the samples, the inhomogeneity of the distribution of the carbide phase over the cross-section of the bolts was established. The two-phase composition (a-Fe + Fe3C) of steel was established by X-ray structural analysis, which confirms the results of microstructural studies. It should be noted that the phase composition of all studied samples is identical. Based on the results of the studies carried out, it was found that the destruction occurred due to the reduced strength and increased fragility of the material due to the presence of microdefects. The material of the whole bolts in terms of structure and mechanical properties comply with regulatory requirements.
ANALYSIS OF LOCAL FIELDS OF ELASTIC STRESS GENERATED BY ROTATIONAL-SHEAR MESODEFECTS NEAR THE JUNCTIONS OF GRAINS

Published: July 2021

The work is devoted to the study of the structure of the elastic stress field in the area of junctions of grain boundaries containing strain-induced rotational-shear mesodefects. The jumps in plastic distortion of grains when passing through grain boundaries create additional misorientations on them, the mismatch of which at the junctions of grains leads to the appearance of linear mesodefects of the rotational type – junction disclinations. Planar mesodefects of the shear type appear on the flat sections of the boundaries, which are plastic shears uniformly distributed along the boundaries. These mesodefects create spatially inhomogeneous elastic stress fields near the junctions and ledges of the grains. They increase during plastic deformation and, at sufficiently large value of strain, initiate the formation of a fragmented material structure. Rotational-shear mesodefects are also the cause of the nucleation and accumulation of microcracks at the stage of viscous fracture of polycrystalline solids.

In this work, asymptotic formulas are obtained that make it possible to analyze the distribution and anisotropy of the internal stress field in the vicinity of the grain junction from rotational-shear mesodefects. It was found that the components of the stress field weakly depend (logarithmically) on the length of the grain boundaries formatting junction of the grains. It is shown that the screening disclination of the dipole leads to the appearance of an angular dependence of the diagonal components of the elastic stress tensor in the vicinity of the junctions and its contribution to the elastic field of the disclinations dipole is about 10–15%. The obtained asymptotic expressions can be used to study the kinetics of a dislocation ensemble and to analyze the conditions for the nucleation of microcracks in the vicinity of joints and ledges of grains.
ENHANCING THE EFFECTIVE FUNCTIONING OF INTERSECTIONS WITH INTENSIVE TRAFFIC AND PEDESTRIAN FLOWS
Authors: Renkas A. , Rudenko D. , Tovaryanskyy V.
Published: July 2021

Introduction. Problematic sections of the road network are intersections with high traffic intensity of conflicting pedestrian and traffic flow, in particular, right and left turns. At such crossings, there are significant traffic delays. In the case of vehicles turning left or right at an intersection when passing at a traffic light signal that allows traffic, should give way to pedestrians crossing the roadway on the crosswalk. In the case of high intensity of pedestrian traffic, it is impossible to complete the turn of such vehicles, they remain at the intersection, so there are significant traffic delays for returning vehicles.Purpose. Therefore, the work aims to study the interaction of traffic and pedestrian flows with high intensity at regulated intersections to improve their capacity.Methods. To study the parameters of traffic flows, in particular, the length of congestion, we used traffic flow models, which include a psychophysiological model of following a vehicle moving in front, and a model based on traffic rules. To model, pedestrian flows the Wiedemann model was used. The leastsquares method was used to obtain empirical nonlinear dependences of congestion length on the intensities of conflicting pedestrian and traffic flows.Results. The paper uses known methods for solving applied problems in the field of traffic for some unique cases, namely the intersection of intensive -traffic and pedestrian flows. Studies of road and pedestrian traffic parameters at crossings have shown that the length of congestion significantly depends on the intensity of traffic flow, but with increas-ing intensity of pedestrian traffic more than 1000 people/h, the length of congestion changes insignificantly. If there are trams at the intersection, the length of congestion increases by an average of 1.14% and depends significantly on the intensity of traffic and pedestrian flows.It is proposed to introduce three-phase traffic light regulation on such sections when one of the phases allows traffic only for pedestrians. The simulation results showed that the length of congestion in the absence of rail vehicles on the approaches to the intersection decreases by an average of 45.3% and is weakly dependent on the intensity of pedestrian flows. If there are rail vehicles at the crossing, the length of congestion can reduce by an average of 13.7%. But in some cases may increase.Conclusion. The research methodology presented in this paper can be used for intersections with another traffic organization scheme to justify the feasibility of introducing threephase traffic light control when one of the phases allows traffic only to pedestrians.

Introduction: Nowadays, deep learning and convolutional neural networks (CNNs) have become widespread tools in many biomedical engineering studies. CNN is an end-to-end tool, which makes the processing procedure integrated, but in some situations, this processing tool requires to be fused with machine learning methods to be more accurate. Methods: In this paper, a hybrid approach based on deep features extracted from wavelet CNNs (WCNNs) weighted layers and multiclass support vector machine (MSVM) was proposed to improve the recognition of emotional states from electroencephalogram (EEG) signals. First, EEG signals were preprocessed and converted to Time-Frequency (T-F) color representation or scalogram using the continuous wavelet transform (CWT) method. Then, scalograms were fed into four popular pre-trained CNNs, AlexNet, ResNet-18, VGG-19, and Inception-v3 to fine-tune them. Then, the best feature layer from each one was used as input to the MSVM method to classify four quarters of the valence-arousal model. Finally, the subject-independent leave-one-subject-out criterion was used to evaluate the proposed method on DEAP and MAHNOB-HCI databases. Results: Results showed that extracting deep features from the earlier convolutional layer of ResNet-18 (Res2a) and classifying using the MSVM increased the average accuracy, precision, and recall by about 20% and 12% for MAHNOB-HCI and DEAP databases, respectively. Also, combining scalograms from four regions of pre-frontal, frontal, parietal, and parietal-occipital and two regions of frontal and parietal achieved the higher average accuracy of 77.47% and 87.45% for MAHNOB-HCI and DEAP databases, respectively. Conclusion: Combining CNN and MSVM increased the recognition of emotion from EEG signals and the results were comparable to state-of-the art studies.

Introduction: Attention-deficit/hyperactivity disorder (ADHD) is one of the most common childhood psychiatric disorders characterized by poor attention and subsequently lower learning abilities than normal children. This study aimed to compare the effectiveness of neurofeedback and perceptual-motor exercises as two common nonpharmacological treatments for visual attention. Methods: A total of 40 combined medicated ADHD children (aged 5-12 years) were randomly allocated into two groups: neurofeedback training and perceptual-motor exercises. Visual attention and motor proficiency were assessed before and after the treatment by continuous performance test (CPT) and Bruininks-Oseretsky Test (BOT), respectively. Results: According to repeated measures analysis of variance (ANOVA), both groups showed significant improvement in three attention-related areas of CPT, including reaction time, omission, and commission errors (P<0.001), while the difference between the two groups was not significant (P>0.05). However, in the perceptual-motor exercises group, motor proficiency improved significantly (P<0.01). Conclusion: Neurofeedback training intervention, as well as perceptual-motor exercises, are effective in improving ADHD symptoms, and given the similar effect of both interventions and their lack of side effects, perceptual-motor exercises appear to be the more appropriate option for reducing symptoms of ADHD, because of its additional effect on motor proficiency, rich content of purposeful activities, and social interactions.

Published: July 2021

Perkawinan merupakan salah satu perintah agama kepada orang laki-laki dan perempuan yang mampu dalam hal ini yang disapa adalah generasi muda (asy-syabâb) untuk segera melaksanakannya. Karena dengan perkawinan, dapat mengurangi maksiat penglihatan, memelihara diri dari perbuatan zina. Islam mengatur dengan baik dan detail, dengan syarat dan rukun tertentu, agar tujuan disyariatkannya perkawinan untuk membina rumah tangga dan melanjutkan keturunan serta mewujudkan kehidupan rumah tangga yang sakinah, mawaddah, dan rahmah dapat tercapai. Di Kabupaten Wonosobo tepatnya di Kecamatan Sukoharjo pernah terjadi masalah mengenai kedudukan wali nikah bagi anak perempuan yang lahir kurang dari enam bulan. Permasalahan tersebut muncul karena terjadi sebuah pelanggaran norma agama dan susila yang dilakukan oleh orang tua terdahulu sehingga mereka telah hamil diluar nikah yang mengakibatkan bayi yang ia lahirkan tersebut dianggap sebagai anak lahir premature atau kurang dari batas minimal yang ditetapkan oleh Hukum Islam maupun Hukum Negara. Atas dasar kasus tersebut, mengenai wali nikah anak perempuan yang lahir kurang dari enam bulan, Kepala KUA Sukoharjo mengambil kebijakan dengan mengacu kepada Fiqh dan KHI Pasal 100. Namun lebih mengutamakan Fiqh sebagai dasar utama untuk menetukan wali nikah tersebut. Menurut Fiqh Imam Syafi'i apabila kandungan tersebut lahir kurang dari enam bulan setelah umur perkawinannya maka walinya ialah wali hakim. Jadi anak yang lahir tersebut adalah anak ibunya saja  (binti ibu) atau lebih tepatnya anak tersebut dinasabkan kepada ibunya.

Published: July 2021

The focus of this work is to make a significant contribution to solid waste management by designing impact-absorbing bio-composite panels using bio-resin and denim wastes. In this context, composite panels are produced by vacuum infusion technique using both epoxy and acrylated epoxidized soybean oil (AESO) based hybrid resins while denim wastes are utilized as reinforcement materials in fiber and fabric forms. Both physical (fiber density and fiber weight ratio) and mechanical analyses (drop-weight impact resistance and dynamic mechanical analysis (DMA)) of the composites are performed. The outcomes of the study prove that the increase in the AESO ratio of the resin system improves the ductility of the composite and consequently the impact resistance. On the other hand, dynamic mechanical analysis results indicate that the AESO plug-in reduces the storage module and increases the damping factor.

O desenvolvimento sustentável está intimamente ligado a dois aspectos: limitação de uso de recursos naturais e desenvolvimento econômico. Nesse sentido, a disposição inadequada de resíduos da agroindústria resulta em danos ao meio ambiente. Por outro lado, a construção civil apresenta uma boa oportunidade para reutilização desses materiais. Assim, com o objetivo de compatibilizar com princípios de sustentabilidade, esta pesquisa investigou materiais considerados resíduos industriais da cultura do arroz. Desse modo, foram caracterizadas tanto a casca de arroz e a cinza proveniente de sua queima quanto a química e física de suas propriedades. Além disso, foram realizados testes de difração por raios X. O primeiro material foi objetivado como substituinte parcial de agregado miúdo e o segundo como substituinte parcial de cimento para uso em argamassas de cimento Portland. Por fim, foram avaliados quatro traços de argamassa (1:3 e 1:4, com e sem adição de cinza) quanto à relação água/aglomerante e resistência à compressão simples. Logo, foi comprovada a possibilidade de execução de argamassas com os materiais avaliados, desde que realizados adequados processos de dosagem.

The author points out that today in the practical and scientific environment there is a doctrine which states that security in penal institutions consists of three components: dynamic, physical and procedural. The elements of physical security provide for the peculiarities of penal institutions construction taking into account the possibility of proper convicts’ protection and supervision, the possibility of ensuring an adequate level of security for both convicts and other persons, reducing the impact of criminogenic contamination on convicts. Procedural security, which provides for the creation of a system of regulatory and legal support for the process of execution and serving a sentence, preventive measures in order to prevent violations of the regime in penal institutions, ensuring convicts’ isolation, pass control, etc. Dynamic security is a special type of management of a penal institution, which is based on the principles of organizing criminal-executive and preventive activities related to the relationships between the staff of penal institutions and convicts. Despite the three components of this type of activity, special attention is paid only to dynamic security, which negatively affects the functioning of the entire system, the purpose of which is to correct and re-socialize convicts, ensure security in penal institutions, reduce post-penitentiary criminality. With this purpose, it is necessary to focus attention on the following areas of reforming the penitentiary system of Ukraine: using solitary confinement at night, building new penal institutions in accordance with the positive practice of other countries; reformatting national criminal-executive legislation, especially in the field of applying preventive measures; establishing approbation supervision over persons who are released from penal institutions; reducing the level of staff turnover in the State Criminal and Executive Service of Ukraine. Key words: penal institution, security, convict, physical, procedural, dynamic security.

Published: July 2021

The regenerative activity of the protein kinase A inhibitor was investigated using externally on the model of the flap skin wound. The pronounced wound healing effects of the protein kinase A inhibitor had been revealed. They are based on the activation of mesenchymal progenitor cells. The development of this phenomenon was associated with the direct influence of the protein kinase A inhibitor on mesenchymal progenitor cells. The most significant stimulation of their growth potential occurred in the context of the impact of growth factors in particular fibroblast growth factor secreted by the stromal cells. Moreover, in situ, there was an increase not only in proliferating activity but also in the intensity of the specialization processes of progenitors. Without cytokines stimulation, the change in the pattern of cellular cAMP-mediated signal does not affect the maturation rate of precursors.
Reintroduction of nitrofurantoin in the treatment of uncomplicated urinary tract infection
Authors: Mahboob Sabiha , Rahman Md. Sayedur
Published: July 2021

The present study was designed to reintroduce an older antimicrobial nitrofurantoin among a group of prescribers and to explore the relationship between the reintroduction and corresponding shift in sensitivity pattern of the microbes. The microbial sensitivity against ciprofloxacin before intervention was 46.6%, which significantly increased after intervention (51.8%). Treatment with nitrofurantoin resulted in a total clinical cure rate of 80.6%, of which rate of clinical cure achieved in expected time was 66.1% and delayed was 14.5%. The rate of total clinical cure with nitrofurantoin corresponded closely with the proportion of urinary isolates sensitive to nitrofurantoin. i.e., 86.3%. This preliminary study revealed that revival might be an effective strategy to increase the sensitivity and to delay the emergence of resistance.
