A partir de las simulaciones realizadas con dicho modelo se encontraron varios parámetros que determinan el comportamiento de los electrodos, luego basándose en estos resultados se prepararon experimentos donde se pudieran estudiar los efectos de los parámetros en electrodos reales en condiciones de operación.
Quo Vadis, Market Economy? Challenges of Sustainability and Values, Possible Answers
Authors: Kocziszky György
Published: April 2023

Over the past half century, mainstream economics, the theoretical basis for the functioning of market economies, has contemplated value-neutral models paradoxically disconnected from reality. The forced abstraction of these models, as well as the fact that economic policies have been dominated by deregulation and liberalization resulted in a situation where markets have not been able to handle crises properly, and they themselves have become the causes of them. In this study, the author claims that there is a solution: a sustainable market economy, based on the reintegration of value orientation into market processes. In other words, a paradigm shift is needed with sustainability in its focus. But sustainability is just a buzzword, as long as we fail to realize the fact that we have limited room for manoeuvre in society and economy, and we cannot do everything we would otherwise have the opportunity to do. Knowing this, we can state it with certainty that only those nations will be successful in the 21st century that find the path to a sustainable market economy and are able to follow it. The model outlined by the author suggests directions for implementing this idea.

A fenntartható gazdaság finanszírozása Magyarországon, lehetőségek és kihívások: dekarbonizáció, zöld átállás, fenntartható pénzügyek, központi bank
Authors: Kandrács Csaba

Napjaink elnyúló krízisei – a Covid-járvány, az orosz–ukrán konfliktus, az energia- és klímaválság – mind olyan hatások, amelyek Magyarország klímasemlegessé válását sürgetik, de rövid távon nehezítik azt. Több kutatás is megállapítja, hogy hazánk az előirányzott dátumra, legkésőbb 2050-re, képes elérni a kívánt célt, és ez összességében nem makrogazdasági áldozatokkal, hanem inkább előnnyel jár. Ugyanakkor minden zöld átálláshoz, így a magyar gazdaságéhoz is óriási mértékű beruházási és finanszírozási igény is társul, amelynek biztosításához nélkülözhetetlen a magánszféra bevonása, amit a jegybankok érdemben tudnak segíteni. Szerencsére az utóbbi időben megjelentek a zöld, illetve fenntartható beruházásokat finanszírozó pénzügyi megoldások, bár egyelőre még a folyamat elején járunk. A hazai zöld finanszírozás fejlődése érdekében a Magyar Nemzeti Bank (MNB) számos intézkedést hozott és tervez kialakítani, amivel a fenntartható pénzügyi rendszer kialakításán túl hozzájárul a környezeti szempontból fenntartható gazdaságra való átálláshoz.

Influence of HCl concentration in source solution and growth temperature on formation of α-Ga2O3 film via mist-CVD process
Authors: Wakamatsu Takeru , Takane Hitoshi , Kaneko Kentaro , Araki Tsutomu , Tanaka Katsuhisa
Published: April 2023

We have examined the effect of synthesis conditions on α-Ga2O3 film, one of the ultra-wide bandgap semiconductors, on c-plane sapphire substrate via mist CVD process. The resultant film is dominantly composed of α-Ga2O3 phase, but a small amount of κ-Ga2O3 phase coexists when the growth temperature is higher. The source solution containing higher concentration of HCl expands the range of temperatures at which single-phase α-Ga2O3 is grown and suppresses the inclusion of κ-Ga2O3 at higher growth temperatures. Moreover, the growth with higher concentration of HCl up to 0.66 mol l−1 increases the growth rate and improves the surface roughness. Thus, HCl has a crucial role in the selective growth of α-Ga2O3 and the quality of the film. Also, some pits are observed at the surface of α-Ga2O3 and κ-Ga2O3 is precipitated inside the pit defect when the concentration of HCl is low and the growth temperature is high.

The aerodynamic properties of the components of the grain pile during its post-harvest processing are one of the most important parameters affecting the quality of the resulting grain and seeds. Existing devices are considered that allow establishing the speed of soaring of grain materials, their shortcomings and limitations are noted. A sail pneumatic classifier has been developed that provides smooth adjustment of the air flow rate and high accuracy of its measurement. Experimental studies have been carried out to establish polygons for the distribution of soaring speeds for a number of grain materials using the developed classifier. It has been established that the ranges of soaring speeds for different crops differ significantly. The soaring speed ranges for wheat and bindweed buckwheat do not intersect, which allows them to be completely separated using an air flow at a speed of 5.91-8 m/s. The soaring speed of sorghum (8.37-10.02 m/s) is completely covered by the range of this indicator for wheat, so it is not possible to separate them using aspiration systems. The ranges of critical rates of millet, vetch and wheat partially intersect, which indicates the impossibility of complete separation of these impurity components without loss of grain of the main crop. At an air flow rate of 9 m/s, 96.9% of the impurity component will be released from the wheat-millet grain mixture with technological losses of the main crop at the level of 4%. Even with a slight increase in the air flow rate, a significant increase in wheat losses is inevitable. Vetch can be completely separated from wheat at an air speed of 11 m/s with a loss of 1.8% of wheat. The results of the performed studies are necessary to improve the efficiency of the use of pneumatic separating equipment through the use of reasonable rational operating modes.

The diversity of natural conditions and cultivated crops, the different level of fields cultivation determines the difference in optimal design parameters and functional properties of sprayers for their effective use. Field experiment methods, calculation method and computer simulation method are used to substantiate the optimal parameters of sprayers in relation to various conditions. In computer modeling, not only the structural, but also the dynamic characteristics of the units are necessarily taken into account. One of the stages in computer modeling of the spraying units functioning is the preliminary formalization of non-stationarity and non-linearity of their static and dynamic properties. The formula for the dependence of the main moment of inertia of the sprayer at a different level of liquid in a cylindrical container was obtained by formalizing the results of a full-scale experiment. The original stand and the method of carrying out are proposed for conducting a full-scale experiment. The mathematical dependence of the change in the height of the center of mass of the spraying unit on the design parameters of the tank and the liquid level in it was obtained by the calculation method. The results obtained can be used in Simulink modeling of the functioning of the spraying unit and determining its optimal parameters for various operating conditions using a known method.

The strength properties of grains must be taken into account in the development and modernization of machinery and equipment for the implementation of many technological processes in agricultural production. Known devices and methods for determining the forces of destruction of grains under external influences are considered. A device has been developed for studying the process of deformation and destruction of grains under static compression, which makes it possible to establish the strength properties of various grain materials. The results of studies on the deformation and destruction of wheat grain under static compression are presented. It has been established that, regardless of the spatial orientation of the grain, the dependence of the deformation on the loading force has straight sections, indicating its uniform compaction. An abrupt increase in deformation occurs when the grain of wheat is oriented with the groove up and the load P = 10.37 kgf, after which there is no significant increase in deformation with an increase in P to 11.67 kgf. With further loading within P = 12.04 - 15.18 kgf, the grain deformation increases again with its compaction. At a load P = 15.55 kgf, an abrupt increase in deformation is again observed, after which the grain was destroyed. In the case of grain orientation with a groove down, a characteristic jump-like increase in its deformation occurred at a force of 17.31 kgf, which is 6.94 kgf more than in the opposite placement. After that, the dynamics of deformation increased significantly, and the destruction of the grain occurred at a force of 19.25 kgf, which is only 3.51 kgf higher than the similar value for the grain oriented with the groove up.

The humidity of harvested grain in many regions of the Russian Federation is higher due to the peculiarities of climatic conditions. The efficiency of drying devices is determined by the use of energy-saving technologies. Reuse of waste coolant in dryers is proposed in the technological process of grain drying. The assessment of the main factors influencing the process of drying a wet grain heap has been carried out. Simulation of grain drying when heated air, obtained by cooling the grain after drying, is supplied to the combustion device of the dryer. A special computer program was used to calculate technological indicators. The program allows you to determine the economically feasible mode of operation of the drying equipment in the process of post-harvest processing of grain. The numerical values of the variables that are set depending on the grain processing mode and the productivity of the dispenser and dryer are defined for working with the program. The consumption of diesel fuel and natural gas for drying grain, depending on the moisture content of the grain heap and the productivity of the dryer, was determined during the simulation of this process. The hourly consumption of diesel fuel and natural gas for drying grain, depending on the moisture content of the grain heap, was determined. The dryer capacity varied from 5 to 40 t/h. The results of fuel consumption modeling showed that drying grain using the heat obtained by cooling the seeds and sent to the furnace units of the dryers can reduce fuel consumption by 20%.

A method for improving the reliability of agricultural trailers by replacing steel sides with composite sandwich structures is considered, which makes it possible to reduce their weight with a general improvement in performance. The fastening of such boards to the metal frame of the platform is carried out using steel supports. Carrying out loading and unloading operations can be carried out by overturning the side board around the lower hinged supports, with the opening of the latches on the two upper supports. A comparative analysis of the existing methods of joining "steel-composite" (adhesive, with the help of mechanical fasteners, combined, glue-pin) made it possible to identify their shortcomings when using a multilayer composite structure characterized by insufficient strength of the inner layers adjacent to the support. The design of the lower hinged support, devoid of the described shortcomings, has been developed. The connection is carried out using two steel lugs containing profiles with spearshaped fasteners, which are introduced into the skin prepregs at the stage of composite manufacturing. The lugs are tightened with bolts, which allows you to create a reliable connection between the steel hinged supports and the side plate, which consists of a multilayer composite. A method for calculating the lower support has been developed, as a result of which the most loaded fasteners have been identified, and an expression has been obtained to determine the maximum acting force. Recommendations are proposed for calculating the strength of the most loaded fastener according to the allowable shear stresses of its cylindrical part.

Nahwu science now contains philosophy, so it isn't easy to learn. In addition, the science of nahwu compiled by classical scholars reduces it to one qorinah or guidance, namely, I'rob. Most words in Arabic end with the letter 'Ilat which cannot be identified with I'rob. The aims of this research are twofold, namely (1) to explain the new theory in nahwu science which Tammam Hassan carried out. (2) explain its effect on nahwu learning materials for non-Arabic speakers. This research is qualitative, and the type of research is library research. The data sources in this study were divided into two, namely primary with the works of Tammam Hassan and secondary with related journal articles and books. Meanwhile, the data collection technique uses documentary techniques. Meanwhile, the data analysis technique used content analysis. The result of this research is to offer tajdid al-nahwi Tamam Hassan namely al-Qarain al-Lafdziyyah. al-Qarain al-Lafdziyyah has several qorinah, including: al-I'rab, al-Rutbah, al-Shighah, al-Muthobaqah, al-Rabt, al-Tadham, al-Adat, and al-Tanghim. Its influence makes al-kalimat divided into seven, including: al-ism, al-washfi, al-fi'li, al-dhomir, al-dzorof, al-kholifat, and al-'adat. then al-Zaman is divided into two namely al-zaman al-nahwi and al-zaman al-shorfi. while al-dhomir is divided into two namely al-Khudur and al-Ghoibah. then al-Khudur includes al-takallam, al-khatab, al-isyarah while al-Ghaibah includes al-Syakhsiyah and al-Mausufiyah. With al-qarain al-lafdziyah, it greatly influences broader and understanding nahwu learning. Therefore, researchers, educators, and students must explore it.

This study aims to analyze, understand, and describe: 1.) How to use the Ummi method at SD Muhammadiyah Wirobrajan 1 and an-Nahdliyah method at TPQ Nurul Anwar Rembang. 2.) What is the quality of the pronunciation of hijaiyah after applying the Ummi Method at Muhammadiyah Wirobrajan 1 Elementary School and an-Nahdliyah Method at TPQ Nurul Anwar Rembang.  3.) The differences between the Hijaiyah pronunciation Ummi method and the An-Nahdliyah method. This study uses the approach of descriptive qualitative—a collection of results through interviews, observation, and documentation. Data analysis techniques include data reduction, data presentation, and conclusions. The informants in this study were school principals, the Vice Chairman of Curriculum, students, and BTAQ teachers. The study's results used the Ummi method at Muhammadiyah Wiro 1 Elementary School to increase students' fluency in Hijaiyah pronunciation, which is not quite suitable because BTAQ teachers still need to be certified and are still in the mentoring process. And then use of the an-Nahdliyah method to increase students' fluency in pronouncing hijaiyah is maximized because the learning is carried out intensely.

Authors: Pronyuk А. А.
Published: April 2023

On the basis of fishing statistics and research by observers on fishing vessels, an analysis was made of the distribution of capelin catches, the main indicators of fishery (effort, average daily capacity) were considered; length composition of the species was analyzed. It has been established that in 2018 and 2022 the most conductive conditions for capelin fishery, both in terms of capacity and the length composition of the species, were formed in the second half of February and in March in the economic zone of Norway. The reasons for the incomplete realization of the russian quota of capelin in 2018 were the non-optimal timing of fishing by the main group of vessels, in 2022 – an insufficient number of fishing efforts. In March 2018 and 2022, difficult weather prevailed at the fishery, which could prevent the effective realization of the russian quota of capelin.

Home in the Poetry of Saudi Arabia Poets: Khalid Al-Faisal an Example of a Distinguished Arab (1)
Authors: Dahami Dr. Yahya Saleh Hasan
Published: April 2023

The term "homeland" refers to the place and things that a poet associates with his humanity, such as his thoughts, pain, and chanting. The focus of this investigation is on the Saudi Arabian poet Khalid Al-Faisal and the concept of home. It consistently makes an effort to illuminate some literary traits of current Saudi poetry, such as the theme of familial attachment. The topic of "homeland" is given particular attention in the study as a sign of the direction current Saudi Arabian poetry is taking. There is a case to be made that Saudi poetry is presently flourishing among Arab writers, critics, and poets. The researcher wants to emphasize the poet's knowledge while also demonstrating his love for his vast country, the Kingdom of Saudi Arabia, through the beautiful poem "Homeland Desire" by Khalid Al-Faisal. The researcher, on the other hand, makes an attempt to look at the poet's talent in the way he utilized the Arabic language in his poem. The poet's brilliant use of a lovely blending of classical Arabic and vernacular as a metaphor for his love of his vast homeland, the Kingdom of Saudi Arabia, will also demonstrate the poet's brilliance. The research commences with a brief introduction and then a look at the glory of home in Saudi poetry. The main part of the study deals with the Saudi poet Khalid Al-Faisal. The research then employs a critical-analytical approach to examine selected verses from Khaled Al-Faisal's poem "Homeland Passion" (عشق الوطن), emphasizing the concept of home as its primary concern. A brief conclusion to the study is then presented.

Published: April 2023

Objectives: The present study examined the efficacy and acceptability of buffered lidocaine (7.5% sodium bicarbonate and 2% lignocaine with 1:80,000 adrenaline) injection for pain management in dental extractions. Materials and Methods: A hundred patients aged between 20-60 years, according to the recommendations of the American Society of Anesthesiologists (ASA), who required teeth extraction either in maxillary or mandibular arch were considered. Routine exodontia was performed immediately after mixed sodium bicarbonate buffered lidocaine was administered. Simultaneously, the onset time of anesthesia was recorded using a stop clock, whereas pain perceived by the patient during injection and extraction was scored using a visual analog scale. The duration of anesthesia was assessed by the feeling of numbness and the first sign of pain. Results: One hundred patients were administered buffered lidocaine (pH 7.2). They had demonstrated a rapid onset (average of 41.20 sec) of anesthesia, a prolonged duration of anesthesia for soft tissues (average of 3.5 hrs), and low discomfort during injection (62%) and extraction (60%). Conclusion: Buffering lidocaine with sodium bicarbonate reduces the discomfort during the injection and hastens the onset of anesthesia for infiltrations and maxillary blocks when compared to mandibular block with an immersive action that prolongs the duration of soft tissue anesthesia up to 4-5 hrs. It is a simple, economical procedure that a dentist can efficiently perform before local anesthetic administration, making oral surgical operations more comfortable for patients.

Feasibility of combining electrohydraulic processing with cold forging in production of hollow cylindrical parts with bottom made of powdered metal materials
Authors: Dmitriev A.M. , Korobova N.V.
Published: April 2023

The priority of the Russian scientific school in research new structures of parts from metal powders made using electrohydraulic processing is shown. Simultaneously with the achievement of new structures by means of stamping, powder parts are given the required shapes. In the manufacture of powder parts such as cups, the combination of cold forging and electrohydraulic processing opens up new opportunities in increasing the high density of parts at the stage preceding sintering, increasing the depth of the cavity, and reducing the wall thickness of parts. In particular, this makes it possible to make from not passed sintering semi-finished products thin slice for metallographic studies. This technology allows unlimited alloying of iron powder with powders of other metals and the manufacture of deep thin-walled glasses from unique powder steels.

The aim: To determine the financial and economic condition before and after the implementation of the hospital district in the Kalush Central District Hospital and to show the medical and social justi!cation of the changes in the institution’s !nances.
Materials and methods: The object of this study was the activity of the Kalush Central District Hospital, which is a multidisciplinary medical and preventive health care facility, in which medical assistance is provided to patients in surgical, neurosurgical, traumatological, cardiological, gastroenterological, endocrinological, urological departments, in the department of miniinvasive surgery. In order to see how the implementation of hospital districts a"ected the financial condition of medical institutions, the financial statements of the institution for 2017-2018 were used to study the financial condition of the organization. During this period medical assistance was provided to more than 92,000 patients.
Results: The reform of the health care system in 2017 took place in accordance with the developed concept of the development of medicine, which is based on the creation of hospital districts. On average, the hospital district covers about 60 kilometers of territory. Such a distance allows us to deploy a powerful network of various hospitals that are able to provide almost the entire range of medical services, starting from diagnostics and ending with urgent treatment. The hospital district is headed by an institution that coordinates the work of all institutions and recommends building such organizational and financial structures that allow the medical institution to develop and create a quality medical product. Kalush Central District Hospital coped with the reforms of medicine, the implementation of hospital districts became a signi!cant event that changed not only the organization of the provision of medical services, but also changes in the financial and economic condition of medical institutions. In general, the financial condition of the enterprise shows that the hospital is autonomic, it is financed from its own sources of !nancing.
Conclussions: The financial condition of the enterprise shows that the Kalush Central District Hospital is autonomous, that is, to a greater extent, it isfi!nanced from its own sources of !nancing. However, liquidity indicators are negative, which require more e"ective management of cash #ows so that the organization can timely repay salary arrears and pay mandatory payments for the use of material resources and energy. At the same time, a large number of patients are coming to the hospital because the income level has increased, which is de!nitely a positive factor. However, when planning activities for the following periods, it is necessary to take into account the need to update material and technical support, as well as to find sources of increasing sta" wages.

The aim: To de!ne regularities of testicular construction of the rats’ offspring at 1-90 days of postnatal life after the introduction of female sex hormones to pregnant rats during the second and third periods of pregnancy
Materials and methods: The study was conducted on the testes of white laboratory rats’ offspring during three months of life. Pregnant rats were exposed to intravaginal injection of Utrozhestan during the second and third periods of pregnancy. histological methods were used. Analysis of the obtained results was conducted by means of statistical methods with the use of computer license program «Statistica for Windows 13» (StatSoft Inc., # JPZ804I382130ARCN10-J).
Results: Administration of female sex hormones to pregnant female rats leads to a reducing of the relative area, occupied by the convoluted seminiferous tubules with lumen, and increasing in relative area, occupied by extracellular matrix, starting from the 30th and up to the 90th observation day in the offsprings’ testes. During the third month after birth, in experimental group a decreasing of the testicles’ spermatids di"erentiation degree is determined
Conclusions: During the study, the following results and conclusions were obtained: decreasing of the relative area, occupied by convoluted seminiferous tubules, increasing in relative area, occupied by extracellular matrix, also decreasing Leydig cells relative amount and a delaying of spermatid di"erentiation process after exposing to female sex hormones during pregnancy, especially during third period, can lead to disruption of spermatogenesis and spermiogenesis in the future.

Published: April 2023

The aim: To assess the impact of statins on the severity and lethality rate in hypertensive patients with COVID-19-associated pneumonia.
Materials and methods: 106 unvaccinated hypertensive patients were enrolled in the study. 29 (27.4%) patients took statins.
Results: Statins were not associated with reduced risks of lethality (relative risk (RR), 0.24; [95%CI, 0.03–1.79], p=0.16), decline in oxygen saturation <92% during the inpatient stay (RR, 0.70 [95%CI, 0.39-1.28], p=0.25) and need for supplemental oxygen (RR, 0.84; [95%CI, 0.51–1.37], p=0.48). There was no significant difference in the median length of in-hospital stay between the patients taking statins (14.0 [10.0–15.0] days) and patients, which didn’t take statins (13.0 [9.0–18.0] days) (p=0.76). However, subgroup analysis showed that statins reduced the risk of decline in oxygen saturation <92% in patients aged 65 years and older with body mass index $ 25.0 kg/m2 (RR, 0.33 [95%CI, 0.11–0.92], p=0.03).
Conclusions: Statins didn’t a#ect the severity and lethality rate in hypertensive patients with COVID-19-associated pneumonia. Subgroup analysis showed that statin use was associated with a decrease in morbidity of patients aged 65 years and older with BMI $25.0 kg/m2 hospitalized for COVID-19-associated pneumonia.
