A method for measuring capacitive current in distribution networks based on injection signal method
Authors: Yuan Jing , Geng Chong , Gao Yan , Lou Mengyang , Ma Lei 
Published: September 2024

Abstract
In view of the problems that exist in the current distribution network, such as the narrow range of measurement capacitance to the ground and the difficulty of selecting the appropriate signal frequency. Based on the phasor method, this paper proposes a method for measuring capacitance current in a distribution network based on injected signal and analyzes and calculates the error of the method. The measurement technique involves inputting two constant-amplitude signals—one high-frequency and one low-frequency—into a zero-sequence PT (Potential Transformer) configured with an open delta connection. Based on the equivalent circuit models for both high and low-frequency signals, the high-frequency signal’s increased frequency allows the magnitude to be disregarded, simplifying the calculations. Using a simplified equation for the low-frequency signal component, this method enables rapid calculation of the capacitor current in the distribution network. Based on MATLAB software, the simulation calculation model is established, and the simulation results show that the measurement method is simple to calculate and has high accuracy, which can be used to measure the large-capacity grounding capacitance current test, so as to improve the measurement accuracy of the capacitance current of medium and low voltage distribution network.

Authors: Wei Xiangyu , Zhang Ting , Liu Ruizhi 
Published: September 2024

Abstract
According to the power generation principle of solar cells, the mathematical model analysis of photovoltaic cells shows that in order to maintain the maximum output power, the work of photovoltaic cells needs to be maintained at the maximum power point. Energy issues are global concerns, and the rational utilization of renewable energy is key to solving these problems. Solar energy, the most readily available source of energy, is characterized by its cleanliness, renewability, and permanence, meeting the requirements for new energy generation. This paper, addressing the shortcomings of the traditional particle swarm algorithm, proposes an MPPT based on an improved zebra optimization algorithm. This strategy is designed to decrease the energy loss during oscillation processes and increase convergence speed. Its performance advantages are also verified through simulation.

Authors: Temirov S , Khatamov B 
Published: September 2024

Abstract
The development of multifunctional universal working bodies that can perform various functions with quick and uncomplicated adjustment, low energy and material consumption, and ensure high-quality processing of row spacing throughout the entire growing season of plants is in high demand. The project documents were developed for mastering the production of a cultivator with a universal working body and were introduced into the design process at BMKB-Agromash JSC. As a result, a universal working body was developed and installed on the beam of the KXU-4B cultivator, featuring quick and easy adjustment and low metal consumption. The use of a cotton cultivator equipped with universal working bodies in inter-row processing of cotton is expected to reduce labor costs by 16.0%, exploitation costs by 15.56%, and metal consumption of the aggregate by 1.23 times, as well as fuel consumption per hectare of cultivated field by 11.26%. To achieve this, a universal working body was designed that performs all technological operations typically performed by multiple working bodies mounted on existing cultivators without compromising quality. The universal working body is equipped with a wide right and left blade, allowing for the cultivation of the middle of the cotton row, slopes, and weed cutting. The result is a constructive scheme of a universal working body, where working parts are concentrated in one column, enabling the performance of technological operations during different vegetative seasons.

Authors: Tukhtabayev M , Madraximov A 
Published: September 2024

Abstract
This article presents the results of an experimental study on the impact of leading wheel tires 15.5R38 and 16.9R38 on soil. Specifically, the study analyzed the influence of vertical load on the maximum tire pressure (MTA) and internal air pressure on soil. The variations in maximum soil pressures of 15.5R38 and 16.9R38 tires at different internal air pressures depending on corresponding loads were investigated. The characteristics of changes in permissible pressure and loading of tires on soil are graphically depicted, and the permissible standards for their use in agricultural work are determined. Recommendations are provided for using tires at the minimum and maximum permissible internal air pressures. Using values smaller than the recommended values can lead to a decrease in the useful life of the tire.
Study of heat transfer and hydrodynamic processes in a full-size thermosyphon installation under the influence of solar radiation with coolant
Authors: Tyemurkhanov Anver , Tovarnyx Gennadiy , Utaev Sobir 
Published: September 2024

Abstract
This article discusses the theoretical background and results of the study of heat exchange and hydrodynamic processes occurring in a thermosiphon installation. One of the important characteristics of the operation of thermosiphons is their ultimate heat transfer capacity, the calculation of which allows us to create a reliable, highly efficient heat exchange device. For optimal design and improvement of the technical and economic indicators of a thermosiphon installation, it is necessary to develop and improve scientifically based methods for calculating the processes occurring in the elements of its design. The purpose of the experimental part of the work was to test the selected theoretical model and more accurately determine the physical picture of the processes occurring in full-scale thermosiphon installations by measuring not only integral, but also local characteristics of the installation. There is intense heating of the liquid in the collector in the first half of the day (from 11 to 13 hours) and a slowdown in the rate of increase in temperature at the outlet of the collector in the second half of the day. A drop in the level of solar radiation in the second half of the day does not lead to a significant decrease in the temperature at the outlet of the collector, which is obviously explained by an increase in the temperature of the liquid at the inlet to the collector during the period under consideration. The presence of a long period of lag in the increase in the temperature of the liquid at the inlet to the collector compared to the temperature at the outlet is associated with the inertia of thermal processes in the system. The time interval from the beginning of the experiment to the beginning of the increase in the temperature of the liquid at the inlet to the collector coincides with the period of a single circulation of the liquid in the system.

Published: September 2024

Abstract
This study presents the results of theoretical research conducted on the parameters of the working bodies of a turning disk plough. Analytical expressions were derived to determine the longitudinal distance between the working bodies, based on the condition that the located working body is outside the zone of influence on the palm. The calculations indicate that the direction of movement of the working bodies and the installation angles relative to the vertical should be within the ranges of 40-45° and 15-25°, respectively. Additionally, the disc diameter should be at least 600 mm, the radius of curvature should be at least 700 mm, and the transverse and longitudinal distances between the working bodies should be suitable, with values between 30-36 cm and at least 53 cm, respectively.

Published: September 2024

Abstract
The electrochemical method is one of the most promising solutions for oil-contaminated soil remediation by passing small constant electric currents. The creation of installations for the electrochemical treatment of oil-contaminated soils requires an understanding of the ongoing processes, which can be achieved by developing a mathematical model. In this paper, we consider obtaining a mathematical description of the change of the oil pollution concentration from the time of direct current treatment and the distance to the electrodes, followed by experimental verification of the adequacy of the models to real electrochemical processes in oil-contaminated soils. The article shows the main approaches and stages of obtaining mathematical models for assessing the cleaning effectiveness. Mathematical models of pollutant concentration changes of the depending on the time and distance to the electrodes were obtained. A correlation between the most important design parameters of the installation and the parameters of the electrochemical process has been established. The resulting models can be used to design installations for electrochemical treatment of oil-contaminated soils.

Abstract
The article reflects the results of the assessment of the current state and functioning of the green infrastructure of the urban environment. A thorough survey of the territory and a clear functional zoning were carried out. A study of the features of Landscaping and landscaping of urban forests was conducted and a whole range of issues related to the formation of a full-fledged environment for human recreation was identified. The research has established plants that can withstand high temperature conditions and low humidity, high levels of dust and gases in the air of the urban environment, soil compaction, etc. In the course of research, it was revealed that coniferous plants play a large role in the creation of decorative compositions. For a shaded lawn, special types of herbs are used that can do without direct sunlight. Local creators and artists can be involved in the creation of unusual forest art objects. This will create additional interest in visiting and contribute to the dissemination of information about the city and its attractions on social networks, creating an attractive tourist image. The improvement of the city’s forest area will create opportunities for organizing full-fledged recreation for urban residents, and will have a beneficial effect on their psychological and physical condition. Thus, a sufficient number of well-maintained public spaces have a positive effect on the physical and psycho-emotional health of a city dweller, on the effectiveness of his work.

Consequently, an explicit example is presented herein of a quadratic AS-regular algebra of global dimension five that is a graded Clifford algebra having no point modules.
Discovery in leaf litter: uncovering the systematics of Porcelloderes (Heteroptera: Reduviidae: Phimophorinae)
Authors: Ramirez Jamie , Grebennikov Vasily , Weirauch Christiane 
Published: September 2024

Abstract
The subfamily Phimophorinae includes ~113 species of cryptic assassin bugs found in the Neotropics and Paleotropics. Presumably due to its small size, cryptic coloration, and occurrence in the remote Eastern Arc Mountains (EAM), Porcelloderes impenetrabilis Rédei, 2012 (Heteroptera: Reduviidae: Phimophorinae), was only recently described as the first representative of this subfamily from mainland Africa. Previous morphology-based phylogenetic research on Phimophorinae (then known as Physoderinae or Epiroderinae) recovered Porcelloderes as sister taxon to the remaining epiroderine-lineage of Phimophorinae. Recent fieldwork in Tanzania has resulted in 241 additional specimens of Porcelloderes from 3 EAM) ranges. We used molecular and morphological analyses for these 241 specimens to (i) determine their species identity, (ii) test the phylogenetic position of Porcelloderes within Phimophorinae, and (iii) determine if divergence within Porcelloderes coincides with periods of climate-driven forest fragmentation in the EAM. Specimens from the Kimboza and Nguru Mountains likely represent P. impenetrabilis, but we here describe Porcelloderes harles, n. sp., from the Udzungwa Mountains. Our molecular phylogeny shows Porcelloderes nested within the epiroderine-lineage of Phimophorinae and as sister taxon to a Madagascar clade. We estimate that the epiroderine-lineage diverged from other Phimophorinae ~44 MYA. The divergence estimates for the 2 Porcelloderes species is ~15 MYA, consistent with proposed dates for other EAM assassin bugs and a period of forest fragmentation.
Adaptation of feeding behaviors on two Brassica species by colonizing and noncolonizing Bemisia tabaci (Hemiptera: Aleyrodidae) NW whiteflies
Authors: Zhou Jaclyn S , Xu Huaying Karen , Drucker Martin , Ng James C K 
Published: September 2024

Abstract
Bemisia tabaci New World (NW) (Gennadius) (Hemiptera: Aleyrodidae), a whitefly in the B. tabaci species complex, is polyphagous on many plant species. Yet, it has been displaced, albeit not entirely, by other whitefly species. Potential causes could include issues with adaptation, feeding, and the colonization of new-hosts; however, insights that would help clarify these possibilities are lacking. Here, we sought to address these gaps by performing electropenetrography (EPG) recordings of NW whiteflies, designated “Napus” and “Rapa,” reared on 2 colony hosts, Brassica napus and B. rapa, respectively. Analysis of 17 probing and pathway (pw) phase-related EPG variables revealed that the whiteflies exhibited unique probing behaviors on their respective colony hosts, with some deterrence being encountered on B. rapa. Upon switching to B. rapa and B. napus, the probing patterns of Napus and Rapa whiteflies, respectively, adapted quickly to these new-hosts to resemble that of whiteflies feeding on their colony hosts. Results for 3 of the EPG variables suggested that B. rapa’s deterrence against Napus whitefly was significant prior to the phloem phase. This also suggested that adaptation by Rapa whitefly improved its pw probing on B. rapa. Based on analysis of 24 phloem phase-related EPG variables, Napus and Rapa whiteflies performed equally well once they entered phloem phase and exhibited comparable phloem acceptability on both the colony- and new-hosts. These findings demonstrate that NW whiteflies reared on a colony host are highly adaptable to feeding on a new host despite encountering some deterrence during the nonphloem phases in B. rapa plant.

ABSTRACT

Objective
The BETY-Biopsychosocial Questionnaire (BETY-BQ) is a scale developed to assess the biopsychosocial domains of patients with rheumatic diseases under a single roof. The study aimed to determine the validity and reliability of the BETY-BQ in patients with primary Sjögren’s syndrome (pSS).

Methods
At enrollment and 1 week, 91 patients with pSS completed the BETY-BQ. Construct validity was measured by correlating the BETY-BQ total score responses with the Health Assessment Questionnaire, Hospital Anxiety and Depression Scale, 36-Item Short-Form Health Survey, EULAR Sjögren’s Syndrome Patient-Reported Index, EULAR Sjögren’s Syndrome Disease Activity Index, Primary Sjögren’s Syndrome Quality of Life questionnaire, and Euro-QoL 5D.

Results
The BETY-BQ correlated high to moderate with Health Assessment Questionnaire, bodily pain subscale of 36-Item Short-Form Health Survey, Euro-Qol 5D, Primary Sjögren’s Syndrome Quality of Life questionnaire, Hospital Anxiety and Depression Scale, and EULAR Sjögren’s Syndrome Patient-Reported Index (0.776 to 0.557, P &lt; .05). Spearman’s correlation coefficients between BETY-BQ total scores at baseline and average 1 week were very high (rho = 0.98, P &lt; .001) and indicated substantial agreement between test–retest scores (intraclass correlation coefficient = 0.99, P &lt; .001). Internal consistency reliability at baseline was 0.91 for the BETY-BQ.

Conclusions
BETY-BQ is valid and reliable for assessing biopsychosocial status in patients with pSS and can be used to measure outcomes in pSS.
Physical Therapists in Primary Care in the United States: An Overview of Current Practice Models and Implementation Strategies
Authors: O’Bright Katie , Peterson Seth 
Published: September 2024

Abstract

In the USA, physician shortages and increases in noncommunicable disease burden have resulted in a growing demand for primary care providers (PCPs). Patients with physical and functional impairments have been especially affected by these challenges. However, physical therapists are well suited to meet patient needs in primary care settings by working alongside PCPs and other primary health care team members. When included in a primary care team, physical therapists can improve patient access to care, optimize care navigation, and reduce the overall cost of care. Therefore, the purpose of the current perspective was to (1) provide an overview of established integrated primary care models in the USA that include physical therapists in the care team and (2) outline operational and practice considerations for health care administrators and professionals interested in integrating physical therapists into primary care teams.

Impact Statement
Given physician shortages and increasing burden in primary care in the USA, inclusion of a physical therapist in a primary care team can improve patient access to care, optimize care navigation, and reduce the overall cost of care for patients with physical and functional needs.

Published: September 2024

Objective:
We evaluated survival outcomes by primary tumor site in synovial sarcoma (SS) patients with localized and metastatic disease at diagnosis.

Methods:
We conducted a retrospective review of 504 SS patients diagnosed from 1974 to 2020. Kaplan-Meier method, log-rank test, and Cox-proportional hazards regression were used.

Results:
Among 504 patients, 401 (79.6%) presented with localized disease, and 103 (20.4%) with metastases. For patients with localized disease, (1) 5-year OS by tumor site was as follows: 80% (95% CI, 67%-89%) for head/neck, 30% (95% CI, 18%-42%) for intrathoracic, 51% (95% CI, 35%-65%) for abdomen/pelvis, 71% (95% CI, 62%-79%) for proximal-extremity, and 83% (71%, 91%) for distal-extremity. (2) On multivariable analysis, tumor site (compared with proximal-extremity: intrathoracic tumors [HR: 1.95; 95% CI, 1.22-3.16]; hand/foot [HR: 0.52; 95% CI, 0.28-0.97]), tumor size (compared with <5 cm, 5-10 cm [HR: 1.80; 95% CI, 1.14-2.85]; ≥10 cm [HR: 4.37; 95% CI, 2.69-7.11]), and use of neo/adjuvant radiation (HR: 0.54; 95% CI, 0.37-0.79) remained significantly associated with OS. For patients with metastatic disease, (1) 5-year OS was 12% (95% CI, 6%-21%) and (2) the only factor that remained significantly associated with OS on multivariable analysis was surgical resection for the primary tumor (HR: 0.14; 95% CI, 0.08-0.26).

Conclusions:
The primary tumor location plays a significant role in predicting outcomes for patients with localized SS. Even though patients present with metastatic disease, surgical resection of the primary tumor improves their survival. These findings are critical for patient counseling and designing a personalized treatment plan that reflects the corresponding outcomes.
