The use of high-quality polymer film as packaging makes it possible to maintain marketable quality and reduce losses during storage of agricultural products even without additional processing. An overview of the existing control systems for the electrophysical parameters of polymeric materials is presented, the use of which serves as the basis for selecting the correct processing modes with the use of high-frequency electrothermal processing. When measuring the electrophysical characteristics of polymeric materials in multicomponent mixtures using standard testing methods, significant errors occur. In this regard, it is necessary to improve laboratory methods and diagnostic tools to solve research problems by automating the process of accounting for air gaps and studying their influence on the process of controlling the electrophysical parameters of the technological mixture. (Research purpose) The research purpose is developing an automated control system for the installation to determine the electrophysical parameters of multicomponent polymeric materials and studying the effect on the dielectric loss and dielectric permittivity of existing air gaps.

(Results and discussion) We have developed an automated installation for determining the parameters of materials, created on the basis of domestic equipment of the VM-560 model. Methods of hardware and algorithmic implementation of the developed system of automated control of the process of investigation and control of the dielectric losses and permittivity of granular polymeric materials were presented. Experimental studies of the effect of air gaps and insulating material on the electrophysical properties of polymeric materials were performed. Refined electrophysical parameters of multicomponent polymers used in the production of films for packaging materials resistant to ultraviolet radiation have been obtained. (Conclusions) It was shown that the developed control system allowed to increase the accuracy of measurement by 12 percent.

Currently, there is an increased interest in the use of combined autonomous power supply systems based on renewable energy sources in the world. Private consumers of the agro-industrial sector need both electric and thermal energy, while installations should not occupy significant land areas. (Research purpose) The research purpose is substantiating the use of photovoltaic systems of increased efficiency for operation in small installations used for private households and farms of the agro-industrial complex. (Materials and methods) Proposed to use a control system based on maximum power point tracking (MPPT) controllers and silicon elements of increased efficiency for more efficient operation of the entire power complex. (Results and discussion) It have been shown that when equipping an autonomous consumer with power plants, reliability and uninterrupted operation of power systems, as well as the necessary power characteristics, become important. It was determined that the daily operation time of such systems is limited by solar insolation and low radiation flux density. It has been established that for the uninterrupted operation of these systems, a reserve of energy or additional power sources is required, and taking into account the variability of solar activity, their conversion factor should be increased by combined generation of thermal and electrical energy. It was found that the modification of the surface of photocells with silver nanoparticles leads to an increase in power characteristics by 20 percent due to the initiation of the effect of surface plasmon resonance. (Conclusions) It was stated that installations for power supply to autonomous consumers of both the agricultural and municipal sectors based on renewable energy sources (in particular, solar installations), modeled using these methods and technologies, make it possible to effectively provide private consumers of the agro-industrial sector of the economy with thermal and electric energy, and when using combined energy conversion, reduce the occupied areas in calculated per unit of power.

(Results and discussion) It has been found out that all the design features of fermenters (bioreactors) are distinguished by the methods of energy supply: with energy supply to the gas phase; with energy supply to the liquid phase; with combined energy supply. It was determined that the temperature control is carried out by an electric heating plate of 100 watts with a solenoid valve, the gas source is air, O2, CO2, N2; the power supply of the control cabinet is 220 volts, 50 hertz. It has been shown that the presence of an external circulation circuit with heat exchangers, the large height of the apparatus and the length of the tubes create significant hydraulic resistances of the circulation circuits at a speed of 1-2 meters per second of culture fluid in the tubes, which leads to energy losses and the need to have pumps for pumping gas-liquid culture fluids with a pressure not lower than 20-40 meters of water column. (Conclusions) It was found that pumping the medium solution from the growth chamber and back increases the cost of electricity consumed by the bioreactor, therefore it is possible to reduce the pumping speed by increasing the concentration of the components of the enriched medium.

In autonomous drives of highly maneuverable vehicles with adaptive control systems, DC motors have become the most widespread. To control them, pulse width modulation is used, in which the simplicity of the algorithm is combined with high-frequency current fluctuations in the motor windings. When optimizing these modes, it is necessary to choose both the control mode and its parameters correctly, taking into account the specifics of the power source, for example, a battery with limited capacity. (Research Purpose) The research purpose is analyzing the optimal parameters for stream and batch modes of pulse-width control of DC motors from rechargeable batteries. (Materials and methods) For the analysis of control modes, generally accepted dependencies describing the relationship of controlled parameters in transient processes, as well as methods for solving differential equations, are used. A general approximate solution of the equation relating current and voltage is obtained, and its approximation for the flow control mode is determined. (Results and discussion) The obtained solution is studied for the practical feasibility of the stream mode. The corresponding analytical condition is derived, in case of violation of which it is necessary to apply the batch control mode. (Conclusions) The optimal parameters of pulse width modulation are analyzed when controlling drives with DC motors from autonomous power sources. Based on the general solution obtained, the application area of the streaming control mode and the optimal values of the corresponding parameters, as well as the application area of the batch control mode and its optimal parameters are highlighted. The use of the proposed equations makes it possible to improve the quality of drive control, to increase its accuracy, to reduce peak loads and unproductive power losses when driving autonomous vehicles.

Using the example of one of the central regions of Russia, an analysis of statistical data on accidents and planned outages in rural power grids of 0.4 kilovolts for the period 2018-2023 was carried out. (Research Purpose) The research purpose is analyzing statistical data on emergency and planned outages in rural power grids of 0.4 kilovolts and identifying the relationships of these types of outages. (Materials and methods) Used literature sources, collected statistical data on the number of emergency and planned outages. Their analysis was performed by descriptive and diagnostic methods. (Results and discussion) It was shown during the descriptive analysis that there is an increase in outages of all kinds with a peak in 2023. It was determined during the diagnostic analysis that this is due not only to physical and moral wear and tear of the equipment, but also to changes in the accounting procedure for emergency shutdowns adopted in 2021. We have identified a significant impact on the number of outages of the self-isolation period due to COVID-19, as in 2020 the number of planned repairs decreased by 38 percent compared to 2019. It was found that due to a decrease in the number of scheduled repairs, there was an increase in emergency shutdowns in 2022 - by 1.5 times, in 2023 - by 5.7 times. (Conclusions) A correlation analysis was carried out by the number, duration of emergency and planned outages and the total power turned off by types of outages. It was stated that the correlation for all the studied indicators for the period 2021-2023 has become higher compared to the period 2018-2021, as the system for recording outages after the changes in 2021 turned out to be more objective. It was noted that the number of planned and emergency outages has a linear correlation of at least 0.83 for the entire study period.

The air removed from the livestock premises by the forced ventilation system contains a significant amount of heat, that can be usefully used, for example, the supply air heating. Currently this energy saving area in the literature is being actively considered. The amount of heat air had being recovered from the indoor rooms depends on the area’s latitude where the livestock farm is located. The influence of cattle farm area’s latitude location saving heat from the air removed from the livestock premises is analyzed. The calculations for three regions of the Russian Federation’s European part located at different latitudes (Rostov, Tambov and Arkhangelsk), in relation to a 280-head cattle farm were performed. To determine the thermal power extracted from the exhaust air, these rooms thermal and material balances (the latter in terms of moisture and carbon dioxide) for the cold (winter) period of the year were compiled and the exhaust air consumption was calculated. In the calculations, a scheme of intermediate coolant, propylene glycol was considered, that circulates between two heating units, the first -on supply air, the second one - on the removed one were installed. It is shown that the farm’s location area latitude gives a significant impact on the energysaving effect: the more northerly the farm is located, the greater the effect, explaining by different indicators of the regions’ heating period under consideration. An payback period’s assessment for capital expenditures and installation work of this system implementation was carried out. The cost of three KSk3-11 brand heaters, a Grundfos UPS 32-80 F 220 circulation pump, 50 liters of propylene glycol aqueous solution, and 100 m of mounting pipes to material costs are attributed. This assessment showed considered heat recovery system’s expediency using.

One of the herbs drying process’s conscious control’s main prerequisites is its duration’s ability calculating. Currently, the drying process’s approximate methods based on the various dependencies’ approximation calculating are widely developed. To determine the total drying time, there are several simple empirical methods, the most common of which is the drying coefficient, that its duration graphically determining. To justify the drying speed and duration, it is necessary the drying coefficient dependence on the parameters finding that drying process’s course determining. Such parameters at alfalfa drying are coolant’s temperature, velocity and humidity, as well as the green mass layer’s height, its granulometric state and initial humidity. By experimental data processing according to multiple regression analysis program, a general formula for the drying coefficient’s dependence on the main process parameters was obtained. The overall correlation coefficient of the results of processing experimental data on the drying coefficient was 0,93. Due to the use of the values of the drying coefficients of herbs, a formula was obtained by a number of mathematical transformations to determine the duration of drying alfalfa at various parameters. The alfalfa drying’s total time at rational operating parameters, according to this calculating formula, will be 0,75 hours.

Modern livestock is in dire need of high efficient disinfection installation equipped with perfect nozzles. Today, the dispensers (nozzles) in many sectors of the economy - for pesticides’ spraying, in fire extinguishing systems, land irrigation, premises’ humidification, etc are used. Their work effectiveness largely depends on the technical capabilities of nozzles’ devices. Many researchers solve complex problems by the design and technological parameters of nozzles’ devices optimizing for their disperse quality improving. To develop high efficient dispensers and optimize their design-and-technological parameters, it is necessary mathematical models describing the flow of hydrodynamic phenomena during the spraying of liquids. Mathematical dependences for geometric and flow characteristics, as well as centrifugal nozzles’ geometric dimensions with tangential liquid supply determining are obtained. During this research, a centrifugal nozzle, consisting of twisting chamber, a nozzle with dc diameter and a liquid inlet channel with dвx diameter, located in twisting chamber’s center, and the liquid inlet channel that is tangentially located at a R distance between the channel’s axis and twisting chamber’s axis, that will be as liquid twisting shoulder used. In this case, the liquid through the tangential supply channel is twisted and flows out through the nozzle’s connection pipe, and the nozzle’s chamber twisting intensity depends on the liquid’s operating pressure and the R distance. Calculations of the main indicators and laboratory tests’ results of centrifugal type devices’ main characteristics determining are presented, and dependencies of effective mode of their operation’s determining are established.

Existing devices for cows insemination’s visocervical method do not have a tool for this device’s working part heating. This discomfort for animals in the cold season creating, their insemination’s success reducing. Therefore, an apparatus with a heated working part is proposed. This device’s working part requiring temperature by a heater located in this device working part tube’s middle is maintained. This device’s heater uniform tube heating must ensure along its entire length and maintain the tube set temperature within 37-39°C at an outdoor temperature of 2°C and an uneven surface of ±3°C heating. To assess the heaters’ number effect on the tube heating uniformity, a device working part’a mockup sample with various options for the ceramic heaters’ arrangement was tested: 1 heater in the tube’s center, 2 heaters at equal distances along the tube’s length and 3 heaters evenly along the tube length distributing. This heating degree and its distribution along the tube length were recorded by Dannai thermal imager using. This situation was also simulated by the APM WinMachine’s software product using. The required heater’s power from the tube based on the criterion equations’ heat losses was calculated, and also was determined by APM WinMachine using. Modeling by the APM WinMachine package and a field experiment using showed that by this device working part’s uniform heating ensuring, the heater must be either linear or consist of three heaters evenly along the tube distributing. The required heater’s power in WinMachine calculated was 5,20 W, and by criterion equations’ using - 7,72 W, that calculation results’ sufficient convergence for both methods indicating.

Published: October 2024

The present work is research applied to medical students of a university in the south of Santa Catarina with the aim of investigating the presence or absence of racist assumptions and/or content in the education of university students. The questions focused on two specific problems, one about the existence of a centrality of white bodies in examples, books, slides and the like, during medical training, emphasizing the specificities of dermatitis and other symptoms related to the epidermis when they occur in black bodies; and whether students perceived the element of race as a social, theoretical concept, or perceived the element of race as a biological aspect - not just phenotypic. Of the 150 responses, from students from the first to the last period, the results confirmed the existence of a white standard as a model, although students do not necessarily see this as a gap in their own training. On the other hand, regarding the idea of race, the answers were divergent and demonstrate that scientific racism still exists and is institutionally passed on. Empirical research also relies on a decolonial theoretical contribution that seeks to explain the link between modernity and coloniality based on the integration of science as an element that participates in exploration

Objective: In response to the high prevalence and morbidity associated with long COVID (LC), outpatient rehabilitation programmes were created across jurisdictions. We aimed to characterize baseline symptoms and impairments of patients attending outpatient LC rehabilitation.
Design: This study was a retrospective quality-improvement analysis.
Subjects/Patients: Patients attending outpatient LC rehabilitation at the Oxfordshire Post-Covid Service.
Methods: Data included age/sex and 6 questionnaires performed at baseline: Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Dyspnoea-12 (D12), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Assessment-7 (GAD-7), Visual Analogue Scale (VAS) of self-rated health, and the Work And Social Adjustment Scale (WSAS). All scores were dichotomized (indicating presence/absence of clinically significant pathology). Potential differences between age (</≥ 50 years) and sex were assessed using χ2 tests.
Results: A total of 422 patients were included (mean/standard deviation [SD] age = 47.1/13.2;132/31.3% male). A total of 76% had significant fatigue (FACIT-F), 69% had breathlessness (D12), 55% had depression (PHQ-9), 34% had anxiety (GAD-7), 41% self-reported poor health (VAS), and 57% had work/social life dysfunction (WSAS). D12 scores differed between age groups (older > younger, χ2 = 3.19/p = 0.048), with no differences observed on other scales.
Conclusion: In this preliminary study, a high proportion of LC outpatients had significant impairments across domains. The findings of this study reaffirm the need for high-quality, multidisciplinary LC rehabilitation, and may be used to help build a standardized set of outcome measures moving forward.

El trabajo se realizó porque en la comunidad El Cortijo, municipio de Ayutla de los Libres, región Costa Chica del estado de Guerrero, México, hay un aumento de descargas de agua gris doméstica vertidas al río, que provienen de viviendas cercanas a este cuerpo de agua. El objetivo fue investigar el conocimiento sobre el saneamiento de agua gris doméstica en la comunidad El Cortijo. La metodología empleada fue la cualitativa y el instrumento para recabar la información fue la entrevista, además, se realizó un taller dirigido a ciudadanos.
Con los resultados se encontró que la mayoría de los ciudadanos entrevistados no saben que existen métodos sencillos, económicos y amigables con el medio ambiente, para sanear el agua gris de sus viviendas. Se descubrió que la mayoría de las casas ubicadas cerca del río vierten el agua gris al mismo. Se encontró que todos los ciudadanos entrevistados están preocupados por la contaminación del río debido al vertimiento del agua gris, y manifestaron que desean aprender a sanear el agua gris que se genera en sus viviendas. También existen casas que vierten agua negra al río. Se concluye que el poco conocimiento sobre el saneamiento del agua gris doméstica se debe a la falta de difusión de tecnologías apropiadas para este fin.

In forensic odontology, Amelogenin and Sex-Determining Region on Y chromosome genes are commonly used for sex identification. Nevertheless, the amplification of both of these genes encounters limitations in determining sex, primarily due to deletions observed in certain racial groups and the influence of genetic disorders on these genes. This research aims to assess the precision of simultaneously amplifying both genes using multiplex polymerase chain reaction on samples derived from teeth that have been subjected to various forensic conditions. In this study, a total of 70 teeth, comprising 35 males and 35 females, were utilized, and all samples underwent genetic analysis to determine sex following exposure to different forensic scenarios. The findings revealed that both the quantity and quality of genetic material were reduced when exposed to harsh environmental conditions. Notably, the amplification of the sex-determining region on the Y chromosome gene outperformed the amplification of Amelogenin and achieved a sex-determination accuracy rate of 100%. In conclusion, dental pulp serves as a valuable source of genetic material even after exposure to diverse environmental conditions, and it can effectively be used for sex estimation purposes.

The present investigation was carried out to study the oil quality and estimate fatty acid (omega-3 and omega- 6) composition in bottle gourd using gas chromatography-mass spectrometry. Results indicated that the extracted bottle gourd seed oil was estimated to have an oil content (25.2%), polyunsaturated fatty acids viz., omega-3 (6.63%), omega-6 (69.74%) and others (0.17%), which play a major role in, cardiovascular health and has anti-inflammatory, anti-allergic and anti-cancer benefits. It also consisted of saturated fatty acids viz., palmitic acid (9.78%), stearic acid (4.45%) and others (0.97%) along with monounsaturated fatty acids (MUFA) (5.99%) without oleic acid (omega-9). Due to increased demand for specialty edible oil in both domestic and industrial use, it becomes necessary to exploit the potential of bottle gourd seeds as a novel source of edible oil. Being a rich source of omega-6 and omega-3 fatty acids, which lacks omega-9 known for oxidative stability required for storage and cooking, it can be commercialized as cooking oil by blending it with edible oil rich in oleic acid or can also be supplied as an omega-6-rich capsule as a food supplement in future.

Catechists preach the Bible through the practice of catechesis. The proclamation is carried out in a methodical and organic manner. Catechist actors, in particular, focus on evangelizing the general public, both clergy and laity. In the real-world development of the Christian faith, laypeople who become catechists have a complicated responsibility. Because they are directly involved in the lives of the people, they are at the forefront of the ministry work. They are also, in another sense, among people who share God's word with others. The lay catechists' experiences in life have become so ingrained in people's lives. The realities of today are extremely diverse. Even though they live in a time of globalization and modernity, there are still a lot of areas in which civilization has not been particularly developed. Border areas are in many cases being ignored, like places that are sometimes still harder to get to than the development of government centers, like roads that are hard to get to. Catechists face difficulties in providing services due to the scattered location of their service stations. To continue serving under the most difficult circumstances, the catechists need a spiritual spirit to support their efforts in developing religious education in this global world.

When the principle of tolerance is seen as an agreement on shared values, the forms of its practice can be diverse, even contradictory. On the other hand, the relationship between minority and majority groups in Indonesia continues to change over time, and this dynamic becomes a locus of control for the authorities. The government never ignores this problem. In addition to regulations, one of the facilities provided is the existence of Islamic Religious Counselors. The purpose of this study is to explain the role of Islamic religious counselors in realizing harmonious relations for minority groups in freedom of religion and belief. The research method used in this study is a qualitative method with descriptive analysis. The results of the study show the issue in understanding the extent to which the role of divine (heavenly) religious symbols is manifested in the social realm when the majority and minority groups of various religious believers interact with each other in a society, and when each different symbol touches each other intensely. Religious counselors can provide an important foundation for expressing religion amid diversity. The main thing that needs to be underlined is the moderate religious insight and attitude. This is what distinguishes a Islamic religious councelor from other religious figures although both convey religious messages through guidance and counseling activities. The efforts and roles of religious icouncelors are explained from the perspective of religious moderation, harmonization, and freedom of religion and belief. From the perspective of religious moderation, the councelors have a role as an agent of moderation, guardian of morals, and guardian of faith, while from the perspective of harmonization, the councelors have an informative and educative roles, the same thing also in realizing freedom of religion and belief.
Repositioning Religious Organization Activism in The Digital Era

Published: October 2024

The rise of the digital world poses a challenge to the position of religious organizations. This is evident in the emergence of new authorities, both individuals and groups, outside traditional religious structures. Nahdlatul Ulama (NU), a mainstream traditional organization, has also been impacted by this shift. However, several studies indicate that NU has effectively adapted to various challenges and situations over time. This analysis focuses on how NU, as a representative of traditional mainstream Islamic organizations, has repositioned itself in response to the digital era, using the example of its activities in Mojokerto. This work addresses two key issues: first, how NU adapts to the presence of social media; second, what strategies NU employs to reposition itself in the face of these new challenges on social media. To explore these questions, this work employs a qualitative methodology, collecting data through interviews, observations, and documentation. The data is then analyzed and presented using a digital religion approach. The findings suggest that NU has repositioned itself in two main ways. First, through adaptation, by adopting and actively using social media platforms such as Facebook, Instagram, and YouTube via the organization’s official accounts. Second, through a form of resistance, by having NU activists engage on social media without prominently displaying their organizational affiliation.

This article explores the acculturation of culture and religion, focusing on the interaction between Islam and Sundanese culture in West Java, Indonesia. Early Islamic preachers employed accommodating strategies, integrating pre-existing cultural elements, which led to the development of a unique form of Islam in the region. The purpose of this article is to examine and highlight the ways in which Islam has blended with Sundanese culture in West Java. The study utilized a qualitative research approach, combining field research with data from both primary sources (observations and interviews) and secondary sources, such as books, scholarly articles, research reports, and other relevant materials. The data were displayed in a narrative-descriptive format and analyzed using the qualitative data analysis techniques including data condensation, data display, and conclusion drawing. The findings reveal that the long-standing process of acculturation between Islam and Sundanese culture in West Java has produced a distinct Sundanese culture influenced by Islamic principles. This is evident in elements such as the wawacan texts, which contain Islamic teachings, the prevalence of Islamic boarding schools, the practice of Islamic mysticism (Sufism-Tariqa), and the unique Islamic-Sundanese architectural style. The widespread acceptance of Islamic teachings among the Sundanese has led to the incorporation of these principles and traditions into Sundanese society, aligning them closely with Islamic values.
