Published: June 2022

Background: Nearly half of the world's population lives in rural areas where agriculture is the primary source of livelihood (FAO, 2013). Many factors affect the health of agricultural workers, and improving the health of this population will require a variety of approaches. Farmers can experience various diseases and chronic diseases similar to the general population; however, there is evidence that they are at higher risk for acute injuries due to work, certain chronic diseases, and pesticide diseases.
Objectives: This study aims to analyze the factors causing injury in the area of Agriculture.
Methods: This study adopted a cross-sectional explanatory method. The variable consists of several factors that cause injury, namely, vulnerability, threat factors, and ability factors. The population consists of farmers who are members of farmer groups under the assistance of the Lumajang District Agriculture Office. The participants were recruited using multi-step sampling steps with 354 respondents. Data were collected using a questionnaire, which was then analyzed using Structural Equation Modelling (SEM) variance base Partial Least Squares (PLS)
Results: By using the PLS-3 program, the effect of susceptibility factor on injury events is 0.487, and the effect of susceptibility factor on injury events through threat factor is 0.107 so that the total impact of susceptibility factor on injury events is 0.595, the impact of ability factor on injury events is 0.286. The influence of susceptibility factor to injury events through the threat factor is 0.063, so the total impact of the ability factor on injury events is 0, 349. While the threat factor only increases by 21.9% of injury events. So, it can be concluded that the vulnerability factor is the highest factor increasing the incidence of injury by 59.5% compared to other factors.
Conclusion: The development of a injury prevention model can be done by reducing the vulnerability of farmers by limiting working hours in agricultural areas, paying attention to nutrition and fluid intake, controlling accompanying diseases, and facilitating insurance for farmers.

Published: June 2022

В статье рассмотрена математическая модель местоопределения объектов вторжения применительно к радиолокационным техническим средствам обнаружения со сверхбыстрым законом сканирования луча антенны в угловом секторе обзора контролируемой территории. Опыт эксплуатации систем охраны показывает, что для обеспечения зон безопасности морских терминалов, гидротехнических сооружений, акваторий морских портов и т.п. существенным является определение местоположения объекта вторжения на максимально допустимой дальности. Предложенный алгоритм функционирования позволяет учесть различия законов сканирования луча антенны при излучении и приеме сигналов в секторе обзора, а также местоположения по дальности объекта вторжения внутри формируемого «слоя видимости». Полученные аналитические зависимости позволяют повысить потенциальную точность местоопределения лоцируемого объекта за счет устранения методических погрешностей, связанных с применением традиционных алгоритмов функционирования в системах со сверхсканированием. Практическая реализация предложенной математической модели повлияет на общую эффективность систем безопасности, и, в частности, объектов транспортной инфраструктуры.
The article considers a mathematical model of the location of invasion objects in relation to radar detection equipment with an ultrafast scanning law of the antenna beam in the angular sector of the survey of the controlled territory. The experience of operating security systems shows that in order to ensure the security zones of sea terminals, hydraulic structures, seaports, etc., it is essential to determine the location of the invasion object at the maximum permissible range. The proposed algorithm of operation makes it possible to take into account the differences in the laws of scanning the antenna beam when emitting and receiving signals in the viewing sector, as well as the location of the intrusion object within the formed "visibility layer". The obtained analytical dependences make it possible to increase the potential accuracy of locating the object being located by eliminating methodological errors associated with the use of traditional algorithms for functioning in systems with overscanning. The practical implementation of the proposed mathematical model will affect the overall effectiveness of security systems, and, in particular, transport infrastructure facilities.

Authors: Iqbal Muhammad , Riono Dewi Larasati , Tanra Andi Husni , Gumara Yudi 
Published: June 2022

Introduction: Hemorrhoidectomy is one of the most common anorectal surgeries performed in a surgical room or ambulatory clinic. The procedure is linked to severe postoperative pain. Both general and regional anesthesia with spinal anesthesia is used in anorectal surgery. However, these predominantly used anesthesia methods leave postoperative side effects of nausea, vomitus, urinary retention, headache, dizziness, back pain, prolonged inferior muscle weakness, and the level of postoperative pain after the anesthesia wears off.
Case presentation: Three cases of severe hemorrhoids were reported, and they underwent open hemorrhoidectomy with a perianal block. Postoperatively, all cases reported no side effects, minimal level of pain, and faster recovery. Recently, the perianal block has been used to curtail the side effects.
Conclusion: Perianal block is performed by infiltrating the inferior rectal nerves innervating the anus and sphincter muscle. Sedation is sometimes performed prior to injection of the anesthetic block. This technique is considered safe and effective for hemorrhoidectomy.

Abstract
Global coronal models seek to produce an accurate physical representation of the Sun’s atmosphere that can be used, for example, to drive space-weather models. Assessing their accuracy is a complex task, and there are multiple observational pathways to provide constraints and tune model parameters. Here, we combine several such independent constraints, defining a model-agnostic framework for standardized comparison. We require models to predict the distribution of coronal holes at the photosphere, and neutral line topology at the model’s outer boundary. We compare these predictions to extreme-ultraviolet (EUV) observations of coronal hole locations, white-light Carrington maps of the streamer belt, and the magnetic sector structure measured in situ by Parker Solar Probe and 1 au spacecraft. We study these metrics for potential field source surface (PFSS) models as a function of source surface height and magnetogram choice, as well as comparing to the more physical Wang–Sheeley–Arge (WSA) and the Magnetohydrodynamic Algorithm outside a Sphere (MAS) models. We find that simultaneous optimization of PFSS models to all three metrics is not currently possible, implying a trade-off between the quality of representation of coronal holes and streamer belt topology. WSA and MAS results show the additional physics that they include address this by flattening the streamer belt while maintaining coronal hole sizes, with MAS also improving coronal hole representation relative to WSA. We conclude that this framework is highly useful for inter- and intra-model comparisons. Integral to the framework is the standardization of observables required of each model, evaluating different model aspects.
Radiation Effects from the Interstellar Medium and Cosmic Ray Particle Impacts on Relativistic Spacecraft
Authors: Lubin Philip , Cohen Alexander N. , Erlikhman Jacob 
Published: June 2022

Abstract
Relativistic spacecraft, like those proposed by the NASA Starlight program and the Breakthrough Starshot Initiative, will have to survive radiation production that is unique when compared to that experienced by conventional spacecraft. In a relativistic interstellar spacecraft’s reference frame, the interstellar medium (ISM) will look like a nearly monoenergetic beam of charged particles which impinges upon the leading edge of the spacecraft. Upon impact, ISM protons and electrons will travel characteristic lengths through the spacecraft shield and come to a stop via electronic and nuclear stopping mechanisms. As a result, bremsstrahlung photons will be produced within the spacecraft shield. In this work, we discuss the interstellar environment and its implications for radiation damage on relativistic spacecraft. We also explore expected radiation doses in terms of onboard device radiation tolerance.
Energetic Particle Perpendicular Diffusion: Simulations and Theory in Noisy Reduced Magnetohydrodynamic Turbulence
Authors: Snodin A. P. , Jitsuk T. , Ruffolo D. , Matthaeus W. H. 
Published: June 2022

Abstract
The transport of energetic charged particles (e.g., cosmic rays) in turbulent magnetic fields is usually characterized in terms of the diffusion parallel and perpendicular to a large-scale (or mean) magnetic field. The nonlinear guiding center theory has been a prominent perpendicular diffusion theory. A recent version of this theory, based on the random ballistic spreading of magnetic field lines and a backtracking correction (RBD/BC), has shown good agreement with test particle simulations for a two-component magnetic turbulence model. The aim of the present study is to test the generality of the improved theory by applying it to the noisy reduced magnetohydrodynamic (NRMHD) turbulence model, determining perpendicular diffusion coefficients that are compared with those from the field line random walk (FLRW) and unified nonlinear (UNLT) theories and our test particle simulations. The synthetic NRMHD turbulence model creates special conditions for energetic particle transport, with no magnetic fluctuations at higher parallel wavenumbers so there is no resonant parallel scattering if the particle Larmor radius R
L is even slightly smaller than the minimum resonant scale. This leads to nonmonotonic variation in the parallel mean free path λ
∥ with R
L. Among the theories considered, only RBD/BC matches simulations within a factor of 2 over the range of parameters considered. This accuracy is obtained even though the theory depends on λ
∥ and has no explicit dependence on R
L. In addition, the UNLT theory often provides accurate results, and even the FLRW limit provides a very simple and reasonable approximation in many cases.

The phase composition and heat conductivity of (ZrO2)0.9(R2O3)0.1 solid solution single crystals have been studied, where R = (Gd, Yb, Sc, Y), (ZrO2)0.9(Sc2O3)0.09(Gd2O3)0.01 and (ZrO2)0.9(Sc2O3)0.09(Yb2O3)0.01. Single crystals have been grown by directional melt crystallization in a cold skull. The phase composition of the crystals has been studied using X-ray diffraction and Raman spectroscopy. The heat conductivity of the crystals has been studied using the absolute steady-state technique of longitudinal heat flow in the 50–300 K range. We show that at a total stabilizing oxide concentration of 10 mol.% the phase composition of the crystals depends on the ionic radius of the stabilizing cation. The (ZrO2)0.9(Sc2O3)0.1 crystals have the lowest heat conductivity in the 50–300 K range while the (ZrO2)0.9(Gd2O3)0.1 solid solutions have the lowest heat conductivity at 300 K.
Analysis of the experimental data suggests that the heat conductivity of the crystals depends mainly on the phase composition and ionic radius of the stabilizing cation. Phonon scattering caused by the difference in the weight of the co-doping oxide cation has a smaller effect on the heat conductivity.
Possibility for using a low-enriched target to produce 99Mo in the MAK-2 research channel of the VVR-ts reactor

Published: June 2022

Thermal-hydraulic calculations have been conducted with respect to the active part of the MAK-2 loop facility of the VVR-ts research reactor for the 99Mo production. The computational studies were undertaken both for the case of using a highly 235U enriched target and for a low-enriched target. The calculation was performed for the actual technical characteristics of the research channel. The power density for the two simulated cases was obtained in the course of a preliminary neutronic calculation and selected for the most heated channel.
The problem is solved for the steady-state mode of the channel coolant flow and takes into account the dependence of the thermophysical parameters of materials on temperature. The volumetric temperature distribution in the channel was obtained in the process of the calculation.
The calculation results present the maximum temperatures of the target materials for the 99Mo production. An analysis of the obtained results has shown that the maximum temperatures of the aluminum sleeve and the target filling materials do not exceed the critical values. For the analyzed calculation cases, the maximum coolant temperature is localized at a point near the sleeve wall surface and does not reach the boiling temperature for a given pressure. The study has therefore shown that it is possible to reduce the 235U enrichment of the target filling fissile material to 19.7%, provided the average density of the mixture and the amount of 235U in the target remain the same. At the same time, the amount of the medicinally important 99Mo generated will not practically change, which will lead to reduced capital costs for a highly enriched mixture of the target matrix.
