Abstract
The objective of this study was to determine the optimal concentration of boron (B) to obtain the highest growth, yield, and oil content of black sesame. A field experiment was conducted in a completely randomized block design with five treatments and five replications. Treatments included foliar application of B at five rates: control, 50, 100, 150, and 200 mg L−1 at 25 and 35 days after sowing. Results showed that spraying B on leaves increased sesame growth in terms of plant height, number of leaves, and chlorophyll content. Moreover, spraying B increased yield components including the number of pods; the highest pods per plant was 46.2 in the B application treatment with 150 mg L−1 compared to the control with 27.2 pods per plant. The grain yield of the B spray treatment produced 1.10–1.32 t ha−1, with the highest yield at the dose of 150 mg L−1 and the lowest yield at no B spray treatment. Spraying B on leaves at optimal concentration also increased the oil content in seeds up to 5.3% compared to the control treatment. The findings of the study suggest that foliar B application with 150 mg L−1 increases the growth, fruit set, seed yield, and oil content in sesame.

Abstract
Prediction of pollution in water flow is a very important task. To this end, it is imperative to be able to define the uncertainty in a model prediction. This is the purpose of sensitivity analysis whose role is to identify what uncertainty in the model outputs is attributable to the model inputs (parameters in this case). Traditionally, this is achieved by running the model perturbed by many random samples in the parameter space to determine their impact on the model outputs. It provides information on how much of the output variance is controlled by each parameter of the inputs.
The theoretical results related to the procedure based adjoint approach for computing a sensitivity of the response function (RF) to changes in the input source are presented in the paper. It is shown that this approach allows to compute, by one single integration of the adjoint equation over a given time interval, a sensitivity of the RF to any source located in the domain of interest. The proposed approach is applied to the 2D Saint-Venant flow equations for modelling the water pollution problem. A numerical experiment is formulated and implemented for the Thanh Nhan Lake in Hanoi for studying a sensitivity of some RF to observations. The numerical model is constructed by applying the well-known finite-volume method. Two appropriate optimization problems are introduced and solved on the basis of the BFGS algorithm. The numerical results show the efficiency of the proposed method and confirm the theoretical findings.

Soil arthropods respond sensitively to land management practices and correlate with beneficial soil functions. The aim of this research was to determine soil quality using the QBS index in different types of crops and influence of soil variables (pH soil, soil moisture, potassium, phosphorus and nitrogen) on soil arthropods. Between the years 2018 and 2020, we studied different types of crops (Brassica napus, Pisum sativum, Triticum aestivum, T. spelta, Zea mays, Grass mixture and Hordeum vulgare) and recorded 14 taxa. Our results suggest a higher QBS index value in crops grass mixture, Pisum sativum, Triticum aestivum, T. spelta. The EMI value grew with increasing values of soil moisture, soil pH, phosphorus, potassium and nitrogen; indicating the presence of soil arthropods occurring in higher quality soil. Our results suggest that agricultural intensification affects soil arthropods, which are important for the production of biomass, which also affects crop yields.
Meander reshaping – the formation process of a wintering riverbed depression of fish
Authors: Chemagin A. A. 
Published: February 2022

The study of the spatiotemporal distribution of fish is an important and poorly studied aspect of the ecology of aquatic organisms. The research work was performed using the modern hydroacoustic method and geographic information systems. A section in the lower reaches of the Irtysh, a large transboundary Siberian river (in Western Siberia, Russian Federation), was studied. It has a strong development of meandering. The merging (i.e., reshaping of closely spaced meanders and erosion-accumulating channel processes) results in development of wintering riverbed depression, which is a critical “temporal bottleneck” during the winter period of the fish life cycle. The average density of fish in the study area in summer and autumn was 8,031 and 9,194 individuals per ha, respectively. Analysis of the distribution of fish showed that the distribution in the horizontal aspect had a more aggregated character in the autumn. In the vertical aspect, it had a more surface (pelagic) character. The ichthyofauna in the water area of the riverbed depression is mainly represented by cyprinids. The loop-shaped evolution of the channel formed a section of the river with multidirectional, circulating, and counter-current flows. It also created zones with depths exceeding 20 m and aggregations of fish. These features characterize the studied water area as a wintering riverbed depression of the fish of the Lower Irtysh. This section of the river should be included in the list of protected wintering biotopes of fish in the West Siberian fishery basin, which will ensure the conservation of fish at the critical stage of the life cycle.

Background and purpose: Lack of stimulation can cause deviations in child development and even permanent disturbances. The purpose of the study is to determine parenting factors in providing developmental stimulation in pre-school age children in Pakis Sub-District, Malang City, East Java.Methods: This was a cross-sectional study of 120 mothers who have pre-school age children in Curah Ampel Village, Pakis Sub-District, Malang, conducted from September-November 2018. Data were collected with self-administered questionnaire. The questionnaire consists of mothers’ demographic characteristics (age, education, and employment), father’s involvement, knowledge about development stimulation, parenting style, and parental stimulation. Data analysis were including univariable, bivariable, and multivariable analysis conducted with STATA. Results: On average, mother's age was 30 years old, 70.0% with low education, and 83.3% were unemployed. This study found that 55% of parents provide stimulation development that falls in the poor categories. From the result of multivariable analysis with logistic regression, it was found that mother’s education associated with parental stimulation to pre-school age children (OR=0.322, 95%CI: 0.121-0.858, p=0.023). Conclusions: This study highlights that mother's educational background has an important role in providing parental stimulation. Poor parental stimulation can cause developmental delays. A parenting program is needed to develop the knowledge and the ability of parents in accompanying every phase of their child development.

Authors: Olshanetskii V. , Glotka O. , Kononov V. 
Published: February 2022

Purpose of the work. Obtaining predictive regression models, by means of which, it is possible to adequately calculate the mechanical properties of monocrystalline nickel-base superalloys without conducting previous experiments.
Methods of research. For experimental and theoretical studies of temperature performance, a working sample of alloys is formed consisting of known industrialt nickel-base superalloys for monocrystalline castings of domestic and foreign production, which due to contents of the main elements, cover a wide range of alloying. The obtained values were processed in the Microsoft Office with the least squares method, with the obtaining of the "parameter-property" correlation dependencies with the obtaining of mathematical equations of regression models (trend lines) that describe these dependencies optimally.
Received results. The influence of alloying elements on their tendency to the formation of phases in foundry heat-resistant nickel alloys is considered. Based on the influence of elements on phase formation, the coefficient of the ratio of alloying elements Kg¢ in the alloys of this class was first developed.
A close correlation dependence of the ratio Kg¢ with a dimensional discrepancy between the γ- and γ-phases crystalline lattice (localized) was found. It has also been shown that for multi-component nickel systems it is possible to predict with high probability misfit, which significantly affects the strength characteristics of alloys of this class.
The regression models of correlation dependencies on dimensional inconsistency (γ / γ'-misfit) are given, which allow to predict the boundaries of short-term and long-term strength of alloys. It is shown that the magnitude of the misfit at the operating temperature should tend to zero. This will increase the structural stability by minimizing structural stresses, which has a positive effect on the strength and plastic characteristics.
Scientific novelty. For the first time, a coefficient of the ratio of alloying elements Kg¢, which has a close correlation with the strength and dimensional discrepancy of casting nickel-base superalloys, is proposed.
Practical value. The perspective and effective direction in solving the problem of forecasting of the main characteristics affecting the complex of service properties of alloys, both in the development of new monocrystalline nickel-base superalloys, and in the improvement of the composition of known industrial brands of this class, is shown.

Published: February 2022

Purpose. To perform comparative studies of structural features and mechanical properties of test steel for railway wheels with microalloy complex Al + N + Ti and known steel for high-strength railway wheels of brand T, microalloyed with vanadium.
Methodology. Microstructural, micro-X-ray spectral and X-ray phase analyzes were used to determine the structural state of the alloys.
Results. Comparative analysis of the structure and mechanical properties of steels for high-strength railway wheels of brand T and K + Al + N + Ti. It is shown that in K + Al + N + Ti steel after crystallization the structure becomes finer-grained and increase in the volume fraction of perlite was observed in comparison with steel of T brand. It was found that the HPD leads to the decrease in the volume fraction and size of oxides, and in aluminum oxides Al2O3 there is a partial replacement of aluminum atoms by iron and titanium atoms.
Originality. It is shown that the reduction of vanadium content in steel and complex alloying with aluminum, titanium and nitrogen leads to the formation of the finer-grained structure and increase in the volume fraction of fine perlite. In the microstructure of K + Al + N + Ti steel, the formation of oxides, nitrides and carbonitrides was observed, which were located along the grain boundaries and in the body of the perlite grain.
It was shown for the first time that HPD leads to the fact that in the inclusions of aluminum oxides Al2 O3 the partial replacement of aluminum atoms by atoms of iron or titanium, with the formation of oxides of Fe2(Al)O3 and (Al, Ti)2O 3, take place.
Practical value. The use of complex alloying of steel leads to improvement of mechanical properties: increase in toughness at the high level of hardness and strength of steel grade K + Al + N + Ti in comparison with steel of brand T.
Investigation of the formation of a machined surface profile during end milling with a tool with a long overhang
Authors: Dyadya S. , Kozlova О. , Kushnir Ye. 
Published: February 2022

Purpose. Investigate the mechanism of forming the profile of the machined surface when milling with a tool with a long overhang.
Methodology. Experimental method was used with a special stand, which makes it possible to simulate an elastic system of a part with different dynamic properties, record oscillograms of oscillations of a part and a tool during the cutting process. Milling was performed with a milling cutter with cutting modes in which self-oscillations occur. To determine the patterns of movement of the part and the tool, the method of aligning the fragments of oscillograms was used.
Results. The scheme of the formation of the profile of the machined surface under the conditions of milling with self-oscillations by a tool with a long overhang has been investigated. It was found that the free vibrations of the tool after the tooth leaves the cutting zone have a higher intensity than that of the part. This affects the position of the infeed point on the cutting surface. To determine the period and range of self-oscillations of the cutter and the part, the section of the oscillogram with self-oscillations was straightened using the Savitsky-Galei filter. Comparison with the cutting surface of the sections of the oscillogram of the part and the tool during milling showed an identical vibration mode of the cutter. Based on the results of experimental studies, the deviation from the line of elastic equilibrium of the first wave of self-oscillation of the cutter was determined and a graph of its change was plotted. The studies performed have confirmed the previously established effect of deviation from the elastic equilibrium position of the first self-oscillation wave during counter milling on the shaping of the treated surface.
Originality. It has been established that the profile of the machined surface when milling with long overhang end mills is directly related to the deviation of the tool from the elastic equilibrium position during self-oscillation.
Practical value. The obtained results show the effect of a tool with a long overhang on the formation of a machined surface during milling with self-oscillation.

СОЦИОКУЛЬТУРНЫЙ АНТРОПОГЕНЕЗ РОССИЙСКОГО ОБЩЕСТВА: ОБРАЗЫ ОБЩЕСТВЕННОЙ И ЛИЧНОЙ БЕЗОПАСНОСТИ
Authors: Волохова Елена Викторовна 
Published: February 2022

Аннотация. Целью исследования является осмысление социокультурного антропогенеза российского общества в контексте формирования образов общественной и личной безопасности. Принципиально важной для автора статьи становится критическая оценка общественной и личной безопасности через массовые настроения россиян. Также автор статьи определяет цель исследования в понимании взаимозависимости образов общественной и личной безопасности социокультурного антропогенеза российского общества.
Методологическую базу исследования представляют работы в сфере социальной философии и социологии, направленные на междисциплинарный эффект исследования, так как предметная сфера исследования содержит определение социокультурного антропогенеза как формы сфер социальной жизнедеятельности, заданных конкретным типом личности. В таком контексте авторская позиция состоит в выборе теоретико-методологического конструкта исследования, направленного на выявление зависимости образов общественной и личной безопасности от типов личностей в современном российском обществе.
Результаты исследования. Реализуя заданную исследовательскую стратегию, автор статьи приходит к выводу о том, что, во‑первых, в современном российском обществе под влиянием разнонаправленных типов личностей как результатов социальной дифференциации и формирования социальных параллельных миров сложно говорить о дискурсе общей и личной безопасности в общественном пространстве. Во-вторых, анализируя образы общественной и личной безопасности в основных социальных группах и слоях российского общества, автор делает вывод о том, что представления и установки, ориентированные на безопасность, характеризуются смысловыми доминантами в социальной жизнедеятельности групп и слоев российского общества. В-третьих, подчеркивается, что образы общественной и личной безопасности содержат влияние государственнической традиции, что объяснимо в культурно-историческом контексте и социального опыта россиян, связанного с оценкой и осознанием безопасности как альтернативы социальному и политическому хаосу.
Перспективу исследования составляет проблема достижения консенсуса в российском обществе общественной и личной безопасности, что является сложным и долгосрочным процессом в контексте противоречивости типов личностей в российском обществе и их разнонаправленности социальных самооценки и понимания того, что может восприниматься как «хорошее» или «нормальное».

Authors: Beck Cheryl Tatano 
Published: February 2022

BackgroundResearchers are confirming that posttraumatic stress due to traumatic childbirth is significantly associated with lower rates of breastfeeding and low maternal attachment.PurposeThe purpose of this secondary qualitative data analysis was to identify metaphorical expressions women use to describe the impact their birth trauma had on their breastfeeding experiences.MethodsThe primary dataset used to conduct this analysis was a descriptive phenomenological study that focused on birth trauma and breastfeeding experiences of 52 women from New Zealand, the United States, Australia, the United Kingdom, and Canada. Metaphor Identification Procedure was used to identify metaphorical expressions.ResultsSix metaphors were identified. Breastfeeding after a traumatic birth is your head in a vise, an empty affair, mechanical, true grit, a guilt trip, and a form of forgiveness.ConclusionThe six metaphors provide a new voice for women who are attempting to breastfeed following a traumatic birth. Perinatal and neonatal nurses need to be attentive to any of the metaphors new mothers are using to help identify women struggling with the aftermath of birth trauma.
Maisonneuve Fractures of the Ankle
Authors: Bartoníček Jan , Rammelt Stefan , Tuček Michal 
Published: February 2022

» Maisonneuve fractures (MFs), originally described as subcapital (high) fibular fractures with additional injury to the anterior and interosseous tibiofibular ligaments, display a variable injury pattern, ranging from stable to highly unstable fractures.» The high incidence of associated fractures of the posterior malleolus, the medial malleolus, and the anterolateral distal tibia (the “anterior malleolus”) as well as the variable position of the fibula in the fibular notch (FN) warrant preoperative examination via computed tomography (CT).» The main goal of treatment is anatomic reduction of the distal fibula into the FN, which requires prior reduction of displaced posterior malleolar fractures, if present, to restore the integrity of the FN.» Open reduction of the distal fibula into the FN and fixation with 2 transsyndesmotic screws or fixation with a screw(s) and suture-button implant, under direct vision, on the lateral aspect of the ankle joint and anterior tibiofibular alignment are preferred over closed reduction to avoid sagittal or rotational malpositioning, which is associated with an inferior outcome.» Intra- or postoperative 3D CT visualization is essential for assessment of the accuracy of the reduction of the distal fibula into the FN.

Authors: Freiman Halle D. , Mensah Curtis , Codrington Jason , Frick Steven L. 
Published: February 2022

» Idiopathic toe-walking is a diagnosis of exclusion.» The natural history of idiopathic toe-walking has not been studied in many children; we identified only 1 prospective study. Of children without equinus contractures who were toe-walking before the age of 5.5 years, 59% had spontaneous resolution of toe-walking by 5.5 years of age, and 79%, by the age of 10 years.» Adverse consequences of toe-walking into adulthood have not been reported, but may exist, and further research is needed to define and clarify.» If parents desire treatment to resolve their child’s toe-walking, surgical lengthening of the Achilles tendon is the treatment with the highest chance of success and lowest relapse rate, and thus far, no complications have been reported in any surgical series.
