Published: August 2023

The object of the study is the Amudarya River, which is the only source of water supply and domestic water use of the population of the Republic of Karakalpakstan. The studies were carried out because the Republic of Karakalpakstan belongs to the regions of ecological disaster. Therefore, work to reduce anthropogenic pollution's adverse impact on the environment is necessary. The research methods included the sampling of water from the Amudarya River in the established sections of the reservoir according to the seasons of the year for five years, 2016-2020, and the conduct of water analysis following the standard O'zDSt 951:2011 “Sources of centralized domestic and drinking water supply. Hygienic, technical requirements, and selection rules. The indicators of taste, smell, and water color in the studied sections of the Amudarya River correspond to the established hygienic standards. The concentrations of ammonium, nitrates, nitrites, sulfates, chlorides, and total iron in water do not exceed their maximum allowable concentrations. However, the concentrations of turbidity, total hardness, and mineralization of water exceed the permissible values set on them. The maximum turbidity concentrations in water are 39.0 mg/l, total hardness 10.8 mg-eq/l, and salinity 1182.0 mg/l. Based on the work results, monitoring of water quality in the Amudarya River in Karakalpakstan has been improved.
This research aimed to study the long-term quality and assessment of water in the Amudarya River in the territory of Karakalpakstan.

Authors: Eshkobilov Xolikulovich Olim 
Published: August 2023

The paper presents an improved installation and method for determining friction-electro-thermal properties -friction coefficient, temperature, and value of electrostatic charge in the friction contact zone of machine-building composite wear-resistant-antistatic-thermal conducting polymeric materials during interaction with raw cotton. The existing methods and installations working at the frictional influence of polymers and composite materials with raw cotton have been studied. The general disadvantages of existing devices have been revealed, particularly the impossibility of investigating the frictional properties of materials with cotton.
Theoretically and experimentally substantiated principle technological scheme of antifriction interaction of polymeric materials with cotton, where the polymeric material under study is represented as a flat disc rotating in a horizontal plane on which surface cotton is pressed along the normal using a piston in a bottomless box having a cylindrical lateral surface, which leads to minimization of lateral pressure. The developed scheme of antifriction interaction allows maximum imitation of working conditions of working elements of real machines. And also, the antifriction and physical-mechanical properties of composite polypropylene and polyethylene materials filled with organomineral ingredients determined by the developed method and improved installation -tribometer are given.

Published: August 2023

For the 8.2 hectares of the Tupolang hydroscheme near the dam, the measures for its landscaping with the help of a drip irrigation system have been developed. The source of irrigation is infiltration water from the old riverbed. After natural filtration, the water is clear, without mechanical impurities, with a salinity of 0.2 g/l and a flow rate of about 50 l/s. At the end of this pipe, the head is 4 MPa, which eliminates the traditional device of the pumping station to create the required head in a closed irrigation network. This allows the application of these irrigation systems without a pumping station and water treatment. The article presents the initial data for the calculation of drip irrigation:
1. Soils are typical gray soils, non-saline, medium loam by mechanical composition;
2. Groundwaters are at a depth of > 3 m;
3. Mass volume of soils is 1.4 t/m3;
4. Marginal field moisture capacity (MWC) - 28 %;
5. Ultimate moisture capacity is accepted at 85 % of FWP and makes 23.8 %. And most importantly, such irrigation saves water resources.
Epigenetische Veränderungen in Zusammenhang mit
Bewegungstherapie

ZusammenfassungZahlreiche Studien belegen: Wer Sport treibt, reduziert sein Risiko für
Diabetes, Herz-Kreislauf-Erkrankungen und bestimmte Arten von Krebs. Neben den
unmittelbaren Effekten auf Muskeln und Gefäße haben Bewegung und
Sport auch einen direkten Einfluss auf epigenetische Prozesse, die zu einer
veränderten Genregulation führen. Das bedeutet auch, dass
epigenetische Signaturen als molekularer Nachweis von Sport und Bewegung genutzt
werden können. Dazu dienen heutzutage nicht-invasive Methoden auf Basis
von Speichel oder Fingerkuppenblut, um bewegungstherapeutische Effekte zu
analysieren und individuell zu steuern. Das hat zur Folge, dass
molekular-basierte und personalisierte Therapiekonzepte einfacher realisierbar
werden.
Evidenz-Update für ein langjährig bestehendes
Bewegungsprogramm
Authors: Derst Carmen , Alamina Alia , Habersatter Nadine , Prokofeva Daria , Saftig Jane , Gelius Peter , Abu-Omar Karim 
Published: August 2023

ZusammenfassungLangjährig bestehende Bewegungsprogramme ohne regelmäßige
Updates verändern ihre Inhalte fast zwangsläufig aufgrund von
internen sowie externen Faktoren. Dabei besteht die Gefahr, dass sie sich sowohl
vom ursprünglichen Konzept als auch vom wissenschaftlichen Kenntnisstand
entfernen. GESTALT, ein Bewegungsförderungsprogramm zur
Demenzprävention, ist ein Beispiel für ein solches Programm.
Über neun Monate wurde durch ein studentisches Projektteam das Ziel
verfolgt, neue evidenz-basierte Methoden in den laufenden GESTALT-Kursen zu
implementieren. Die Umsetzung eines Evidenz-Updates fand durch explorative
Gespräche mit beteiligten Akteur:innen aus Praxis, Politik und
Wissenschaft, das Austesten neuer Methoden in den GESTALT-Kursen,
Feedbackgespräche und Beobachtungen statt. Die Bedeutung einer
Kennenlernphase des Projektteams mit Praxisakteur:innen und den Teilnehmenden
sowie eine regelmäßige und zielgerichtete Kommunikation aller
beteiligten Akteur:innen erwiesen sich dabei als wesentliche Erfolgsfaktoren bei
der Umsetzung des Evidenz-Updates. Herausforderungen wurden insbesondere
bezüglich der starken Identifikation der Stakeholder mit dem Programm in
der bestehenden Form gefunden. Allgemein schränkten zudem die begrenzten
finanziellen Ressourcen dieses studentischen Projektes die
Umsetzungsmöglichkeiten ein. Zukünftig gilt es zu erkennen,
welche Bewegungsprogramme ein Evidenz-Update benötigen und dessen
Implementierungsprozess so partizipativ und kommunikativ wie möglich zu
gestalten. Außerdem bedarf es der Evaluation solcher Updates, um
fundierte Empfehlungen für andere Projekte und Wissenschaftler:innen
geben zu können.
Pyrrolidinium Acetate (PyrrIL) as a Green and Recyclable Catalyst: Synthesis of 2-Phenyl Benzimidazoles and 2-Phenyl Benzothiazoles under Solvent-Free Conditions at Room Temperature
Authors: Katla Ramesh , Katla Rakhi 
Published: August 2023

AbstractBenzimidazoles and benzothiazoles are a class of pharmacologically potential compounds, which exhibited antimicrobial, anticancer, and anti-inflammatory activities. These can be obtained by simple condensation of o-phenylenediamine or o-aminothiophenol with aromatic aldehydes. The synthetic protocol can be accomplished/improved by varying reaction parameters such as temperature, solvents, and catalysts. To develop such condensation reactions in a sustainable way, nontoxic solvents and eco- friendly catalysts are presently used. In this study, we proposed a novel and interesting strategy for obtaining diversely substituted 2-phenyl benzimidazole and 2-phenyl benzothiazole derivatives via a one-pot protocol, employing pyrrolidinium ionic liquid as a green and environmentally benign catalyst under solvent-free conditions at room temperature in an open atmosphere. The resulting products were obtained in good to excellent yields within a short reaction time (3–20 min). A plausible mechanism was also discussed.

Published: August 2023

AbstractTobacco use and socioeconomic status are related with each other and important determinants of disparities and inequalities to access to care. There is overall reduction in number of smokers but still most number of smokers is represented by people from low socioeconomic status, with less number of these people having an access to the treatment centers. Patients who are tobacco users have shown to be less likely to receive any form of treatment for lung cancer, whether that be chemotherapy, radiotherapy, or surgery. As there is less awareness about signs and symptoms of lung cancer, lower socioeconomic patients are likely to report to hospitals at advanced stages or many times as a medical emergency. We are well aware that patients with advanced lung cancer have lower chances of survival in view of incomplete response to treatment. As there is an intersection between tobacco use, health disparities, and inequalities and lung cancer treatment and survival, this issue needs better focus and attention to minimize disparities and inequalities in access to care and outcomes.

Published: August 2023

Abstract
Introduction It is difficult to comprehend a child's understanding of disease-related information as they might be unwilling to talk or feel inhibited about raising their concerns. Understanding children's perception is important to facilitate better communication in palliative care.
Objectives To study child's understanding of advancing disease when referred to the Pediatric Palliative Care Services.
Materials and Methods A retrospective chart review of 34 case record forms from March 2019 to March 2020 was conducted after obtaining a waiver of consent and Institutional Ethics Committee approval. The inclusion criteria were children having advanced cancer referred for palliative care, incomplete records were excluded. Data were analyzed using thematic analysis.
Results Twenty-three were male, and 11 were female children, the mean age was 12 years. Five major themes were identified—the child's understanding of disease diagnosis and prognosis, nature of communication between parents and the child, barriers to communication, child's means of support, and interventions used during counseling.
Conclusion Communication between children suffering from advanced cancer and their parents/caregivers is a sensitive issue, and noncommunication is often due to mutual effort to shield each other from the stress of difficult conversations. Lack of communication contributes to poor coping and forces children to seek comfort in other sources leaving parents distressed. Psychological interventions like resource building and psychoeducation are effective.

Published: August 2023

AbstractObjective This study aimed to systematically review the literature on homeopathic researches on gout and hyperuricaemia.Materials and Methods A comprehensive online and manual search for research studies on the efficacy of homeopathy in gout and/or hyperuricaemia in clinical trials, in vitro and in vivo experimentation was conducted. All types of studies related to the homeopathic treatment of gout and hyperuricaemia in a human trial, animal experimentations and in vitro experiments on hyperuricaemia, published from January 2001 to January 2022 were considered for review. The methodology was assessed by Jadad scoring for clinical trials, the internal validity of randomised controlled trials by the Cochrane collaboration tool, model validity by Mathie's criteria and the internal validity of observational studies and case reports by the Joanna Briggs Institute (JBI) criteria and JBI appraisal checklist, respectively.Results A total of 16 articles related to homoeopathy on hyperuricaemia and gout were identified, including one preliminary qualitative study, six clinical observational studies, two double-blind, randomised placebo-controlled trials, three case reports, and four animal experiments including one in vitro trial also. Methodological quality analysed by Jaded scoring was diverse, ranging from 0 to 4; by the Cochrane collaboration tool, out of two randomised controlled trials, one had a high risk of bias, while the other had a low risk of bias; observational out of seven studies, only two had a ‘low' risk of bias, three had a ‘moderate' risk and two had a ‘high' risk of bias; JBI appraisal checklist for case report showed two had a ‘low' & one had a ‘moderate' risk of bias.Conclusion This review demonstrates the effectiveness of homoeopathy in all clinical studies, case reports and in vivo and in vitro models studied under the review, but it is difficult to reach a definite conclusion due to a small number of good quality clinical trials, randomised trials and of laboratory experiments.

AbstractIntracranial atherosclerotic disease (ICAD) is one of the most common causes of acute ischemic stroke worldwide. Patients with acute large vessel occlusion due to underlying ICAD (ICAD-LVO) often do not achieve successful recanalization when undergoing mechanical thrombectomy (MT) alone, requiring rescue treatment, including intra-arterial thrombolysis, balloon angioplasty, and stenting. Therefore, early detection of ICAD-LVO before the procedure is important to enable physicians to select the optimal treatment strategy for ICAD-LVO to improve clinical outcomes. Early diagnosis of ICAD-LVO is challenging in the absence of consensus diagnostic criteria on noninvasive imaging and early digital subtraction angiography. In this review, we summarize the clinical and diagnostic criteria, prediction of ICAD-LVO prior to the procedure, and EVT strategy of ICAD-LVO and provide recommendations according to the current literature.
Nonvariceal Upper Gastrointestinal Hemorrhage: The Interventional Radiologist's Perspective
Authors: Rapalino Oscar Mauricio Rivero , García Lorena Garza , Cortes David Fernando Torres 
Published: August 2023

AbstractNonvariceal upper gastrointestinal (GI) bleeding is one of the most common diseases of the GI tract and represents a high percentage of emergency room admissions. Eighty percent to 90% of upper GI bleeds are nonvariceal, with a mortality of 1 to 10% of patients. Selective embolization of the arterial source can be achieved with many therapeutic alternatives available in the interventional radiologist's arsenal, such as particles, coils, liquid emboli, selectively infused vasoconstrictor agents, or a combination of these techniques. Up to 95% of patients can obtain initial hemostasis without angiographic intervention. However, rebleeding is common, occurring in up to 50% of patients and persistent hemorrhage has been described in 7 to 30% of patients with mortality rates up to 14%.
A metasurface featuring multiple polarization conversions
Authors: Sun Jichao , Yang Xiaokun , Zhang Zhengping 
Published: August 2023

This paper proposes a novel bow-tie metasurface that integrates various types of polarization conversions by optimizing traditional unit structures. The metasurface achieves wide-angle linear polarization conversion over the X-band (8–12 GHz) and has a linear polarization conversion efficiency of over 94% under normal incidence. In the Ku-band (12.4–15.6 GHz), the ellipticity value (e-value) and axial ratio calculations show that the linearly polarized waves incident along the Y axis will be effectively converted to left-handed circularly polarized waves. Additionally, in the X-band (8.9–10.5 GHz), the circular polarization and its co-polarization conversion efficiency can be maintained at 99.5%, allowing for an effective circular polarization phase shift using the Pancharatnam–Berry principle in this frequency range.
Research on harmonic resonant fault mechanism and suppression measures of oilfield power grid based on fast mode analysis method
Authors: Liu Na , Zhang Bin 
Published: August 2023

In recent years, with the use of electric drilling rig, electric fracturing pump, and other equipment, the harmonic resonance problem of oilfield power grid is becoming more and more serious. In view of the high time and space complexity and long calculation time of the traditional harmonic resonance analysis method, the improved power iteration method is combined with the traditional modal analysis method, and the harmonic resonance problem of the oilfield power grid is analyzed by the fast modal analysis method. At the same time, a new set of harmonic resonance amplification index is derived and verified, and the harmonic content amplification times in the resonant influence region and different busbars are revealed. And then a passive filter is used to suppress harmonic resonance, and the effectiveness of the scheme is verified by field tests. The results show that, in the frequency range of 0–1000 Hz, the resonant frequency points in the oil field are mainly related to the rectifier pulse number of the drilling rig and the frequency conversion device for fracturing. The proposed fast modal analysis method has the advantages of fast convergence speed and memory saving, which is helpful to accurately detect the harmonic resonance region caused by the multi-pulse frequency conversion device, and the harmonic resonance can be effectively suppressed by installing a filter at the main excitation bus of the resonant frequency.

Published: August 2023

The effects of sulfate on the zinc (Zn) bioaccumulation characteristics and photophysiological mechanisms of the ornamental plant Hydrocotyle vulgaris were explored using a hydroponic culture under three Zn concentrations (300, 500 and 700 mg L−1) with (400 μmol L−1) or without the addition of sulfate. Results showed that: (1) tissue Zn concentrations and total Zn contents increased with increasing hydroponic culture Zn concentrations; and sulfate addition decreased Zn uptake and translocation from roots to shoots; (2) Zn exposure decreased photosynthetic pigment synthesis, while sulfate changed this phenomenon, especially for chlorophyll a under 300 mg L−1 Zn treatment; (3) Zn exposure decreased photosynthetic function, while sulfate had positive effects, especially on the photosynthetic rate (Pn) and stomatal conductance (Gs); and (4) chlorophyll fluorescence parameters related to light energy capture, transfer and assimilation were generally downregulated under Zn stress, while sulfate had a positive effect on these processes. Furthermore, compared to photosynthetic pigment synthesis and photosynthesis, chlorophyll fluorescence was more responsive, especially under 300 mg L−1 Zn treatment with sulfate addition. In general, Zn stress affected photophysiological processes at different levels, while sulfate decreased Zn uptake, translocation, and bioaccumulation and showed a positive function in alleviating Zn stress, ultimately resulting in plant growth promotion. All of these results provide a theoretical reference for combining H. vulgaris with sulfate application in the bioremediation of Zn-contaminated environments at the photophysiological level.
Multi-phase field modeling and simulation of magnetically driven grain boundary migration in SmCo polycrystals

Published: August 2023

Abstract
There is a growing demand for magnetic materials straight forward in wind turbines and electric motors. Their functional properties depend critically on their microstructure and thus on the microstructure evolution during sintering or heat treatment. Field-assisted selective grain growth allows to optimize the microstructure. However, the simultaneous modeling of the structural and magnetic degrees of freedom on the micrometer scale is not possible with most simulation packages. Therefore, we extend the open-source software project OpenPhase and implement the micromagnetic equations needed to treat both degrees of freedom in the framework of the multi-phase field method. We apply our model to the field-assisted grain growth in Sm2Co17 polycrystal films.
