Обоснование перспективной схемы кривошипного гидромотора для гидропривода опорно-поворотного устройства манипулятора лесовозного автопоезда

The task of increasing the efficiency of hydraulic manipulators with traditional column turning mechanisms installed on logging road trains can be solved by installing column turning mechanisms with crank hydraulic motors from hydraulic cylinders. Variants of the arrangement of hydraulic cylinders in a crank hydraulic motor were studied graph analytically by determining tangential and radial forces acting on the rotary column of the hydraulic manipulator. At first, calculations were performed based on static methods to evaluate the effect of forces on the rods of hydraulic cylinders in the working positions of the column rotation mechanism. After that, using the COMPASS computer-aided design system, circular diagrams of tangential and radial forces of the considered options for the arrangement of hydraulic cylinders in a crank hydraulic motor were constructed. Further, in the Microsoft Excel program, graphs of changes in tangential forces acting on the rotary column of the hydraulic manipulator were plotted. Schemes with five and six hydraulic cylinders have the best option of influencing the bearings in which the column is rotated. The ranges of radial forces for them ranged, respectively, from 3.32 to 22.07 kN and from 11.175 to 11.297 kN, and tangential forces – from 257.893 to 285.274 kN, and from 300.471 to 354.059 kN, which can be used in the design of new drive designs for turning columns of hydraulic manipulators. For the practical implementation of the proposed design of the crank hydraulic motor, it is planned to make a rational choice of the location of the hydraulic cylinders of the crank hydraulic motor on the frame of the logging road train on the basis of simulation modeling.

Enhancing Awareness of Diclofenac as an Over-the-Counter Analgesic in the Northern Border Region of Saudi Arabia

Introduction: Diclofenac was identified by the Pharmacovigilance Risk Assessment Committee of the European Medicines Agency as a high-risk NSAID in terms of its effects on the heart and circulation when administered systemically, i.e. capsules, tablets or injections.
 Objective: To evaluate the knowledge and awareness about over the counter analgesic medication (Diclofenac) among people living in northern border region – Saudi Arabia.
 Methodology: Self-administered cross-sectional study conducted during a period of two months (October and November 2023) on random sample of 430 Saudi people living in the Northern Border Region. The data was analyzed by Microsoft excel program by means of Descriptive statistics.
 Results: Toothache and headache were the most worried pain among participants (32%) and (31%) respectively, majority (72%) of participants buy OTC medication for pain from community pharmacy on the advice of pharmacist. Small percentage (20%) thought that medications containing diclofenac have very few side effects, 76% didn’t know any side effect of diclofenac, 47% didn’t know that diclofenac in high dose has adverse effects on kidney, 71% didn’t know that diclofenac cause gastrointestinal adverse effects. About one fifth of participants (21%) didn’t know the maximum dose of diclofenac when they use it, tablet is the preferred dosage form of diclofenac (27%) followed by granules (16%), dosage of 100 mg is the most frequently used (36%) followed by 50 mg (16%). 
 Conclusion: Saudi people’s knowledge about diclofenac as one member of non-steroidal anti-inflammatory drugs was insufficient. Knowledge about related adverse effects of diclofenac was lacked which exposes to misusage that may carry accidents and severe side effects especially among high-risk population.

3D Printed Carbon Framework with the Graphene Aerogel for Microbial Fuel Cell Application

There is a high interest in living organism-compatible materials associated with electrically active interfaces. Bacteria/electrode interfaces implement smart, functional systems with responses, based on which it is possible to elaborate self-regulating energy generation systems. Carbon materials have a number of advantages, such as biocompatibility, low electrical resistance, and the possibility of increasing the electrode surface on an industrial scale. The most promising approach for the industrial production of electrodes is 3D printing. We propose a 3D-printed carbon electrode – a novel lightweight material for electrodes in bioelectrochemical systems for efficient bioelectricity utilization.The pyrolytic process for manufacturing carbon electrodes is promising for upscaling and industrial applications. However, there is a problem of volume loss when 3D-printed polymers are pyrolyzed in an inert environment. We propose a new strategy for the thermal treatment of 3D-printed polymers that allow for reduced volume loss under pyrolytic carbonization. In addition, to achieve a higher electrode surface area, the graphene aerogel could be impregnated into the 3D-printed scaffolds. Chemical modification of graphene surface can enhance biocompatibility. Specifically, the oxidation of graphene leads to forming a hydrophilic and biocompatible material. We tune graphene hydrophilic properties and electrical conductivity via control over the thermal reduction of the oxidized form of graphene–graphene oxide1.Such sponge morphology affords 3D-printed carbon scaffolds an excellent lightweight host scaffold for microorganisms, in which the graphene nanowalls are homogeneously occupied by S. oneidensis MR-1. We demonstrate a novel sustainable method to produce graphene-based lightweight 3D printed electrode materials for green energy production from biomass. The proposed technology creates the opportunity for novel, innovative, disruptive graphene applications that can lead to the establishment of new energy-related industries and facilitate many startups in the ecosystem.

Re-Centering Race in Emancipatory Entrepreneurship: Black Female Tech Founders, Money, and Meaning in a Detroit-Based Incubator Program

This study is an anthropological inquiry into the perceptions and attitudes of Black female tech entrepreneurs towards capitalism in the context of an incubator program in Detroit, USA. Drawing upon ethnographic data from the STEM Entrepreneurial Excellence Program (STEEP), the study reveals the intricate relationships that Black female founders maintain with money and capitalism. These complexities manifest in moral quandaries related to fundraising and distrust in outsourcing financial management, emanating from a long-standing scepticism towards capitalism and intertwined with historical traumas. The research emphasizes the significance of comprehending minority entrepreneurs’ historical inequalities and lived experiences with capitalism to discern their diverse attitudes and performances in entrepreneurship – an aspect frequently neglected in entrepreneurship scholarship. By examining the intersection of race, gender, and entrepreneurship, the essay contributes valuable insights into the nuanced dynamics shaping entrepreneurial experiences of Black women in the technology sector.

Linical Features of Patients with Chronic Kidney Diseases- A Single Center Study

Background: Chronic kidney disease (CKD) is defined as abnormalities of kidney structure or function, present for more than 3 months, with health implications. Preconceptions regarding the clinical features of chronic kidney diseases (CKD) may be helpful for physicians as well as suspected patients, may help manage CKD patients. But in Bangladesh, we have very limited data regarding this issue. Aim of the study: This study aimed to acquire a clear concept of the clinical features of chronic kidney diseases. Methods: This descriptive cross-sectional study was conducted in the Department of Medicine and Nephrology, Dhaka Medical College & Hospital (DMCH), Dhaka, Bangladesh, from March 2018 to September 2020. In total, 150 diagnosed cases of chronic kidney disease (CKD) were enrolled in this study as the study subjects. Properly written consent was taken from all the patients before data collection. All data were processed, analyzed, and disseminated by using the MS Excel program. Results: The mean age of the patients was 53.31±10.28 years; 64% were male and 36% were female. In this study, 34% of patients had CKD stage 5, 28% had CKD stage 4, 25.3% had CKD stage 3, 9.3% had CKD stage 2 and only 3.3% had CKD stage 1. Among our patients, 80% patients had nausea, 74.7% had fatigue and weakness, 65.3% had oliguria, 50.7% had oedema, 28% had fever and 18% had confusion. In 69.3% of cases, hypertension and in 40.7% of cases, diabetes was found as comorbidities. Conclusion: Middle aged male people may be major prone to chronic kidney diseases (CKD). The frequency of hospital admission among stage 1 and 2 are very lower. Nausea, fatigue, weakness, oliguria, and oedema are very common symptoms, whereas hypertension and diabetes are very common comorbidities for patients with CKD.

Calculations of CO2 emission and combustion efficiency for various fuels

The specific CO2 production of fuels has commonly been expressed empirically in terms of kgCO2 (kWh)−1. No specifications regarding combustion conditions, transformation technology used, and efficiency are usually presented in detail. In this paper, however, we propose replacing this approach by the use of rigorous chemical engineering calculations based on the composition and the combustion conditions of the fuels. The MS EXCEL program, which is provided as supplementary material to this paper, calculates the specific CO2 production considering energy losses, adiabatic flame temperature, calorific value and heat of fuel combustion, flue gas temperature, energy losses through flue gas, slag, and the overall energy efficiency of the whole energy conversion process. Results are presented for three fuel groups: coal, hydrocarbons, and renewable fuels. The calculated results are compared with the literature data. A benefit of our approach is that the procedure can be generalized for any fuel of known composition and for different types of combustion-based energy transformation.

Sex Ratio and production parameters of Oreochromis niloticus “Tilapia”

Oreochromis niloticus farming has been affected by excessive reproduction in cropping systems, which causes delayed growth and small sizes at harvest, becoming unmarketable, creating the need to reverse the sex of the females, being possible with hormonal sex reversal techniques such as 17 α methyltestosterone (MT). The objective of this research was to determine the sexual ratio and obtain the production parameters in specimens of O. niloticus with the MT hormone which was supplied in food at 45% protein, with a dose of 24 mg of MT/kg of food, for 28 days. Sex determination was carried out using the squash technique and microscope observation. The information was analyzed using descriptive and inferential statistics at 95% confidence in the Excel program. We worked with 10% of the total population, reaching 95.2% males. The gonads of the females showed oocytes, while in the gonads of males’ spermatocytes were observed, they presented a survival of 96.33%, an increase in weight of 13.46 g and length of 7.82 cm.

A Study on Teachers’ Job Satisfaction in Educational Institutions of All Levels

Those conditions and opportunities are essential for teachers to be satisfied with their work. Furthermore, teachers’ job satisfaction has an important effect on their professional stability and high performance. This study aims to determine the extent of teachers’ job satisfaction at all levels of educational institutions and whether there are differences between educational institutions. The data were collected through the online platform (www.esis.edu.mn) of the education sector. The 10,429 teachers (including university professors) of all levels of educational institutions participated in the survey. In addition, the data were processed using MS Excel and SPSS (Statistical Package for the Social Sciences) programs. As a result of this study, there was a statistically significant difference in teachers’ job satisfaction between educational institutions.

Characteristics of erythropoiesis in sows during different periods of the production cycle

The tactics of periodic monitoring of the hematology of sows allows timely measures to prevent anemia, which inevitably occurs, since the targeted screening and selection of industrial breeds are aimed at multiple births, which increases the risks of anemia during pregnancy and suckling period. With periodic and constant monitoring, it is possible to deduce individual reference intervals of hematological indicators for a particular animal and control the response to compensatory measures that directly affects the yield of viable piglets and their survival rate. The purpose of this study was to study the number of red blood cells, hemoglobin level, hematocrit, average volume of red blood cells and erythrocyte indices depending on the production cycle of the sow. The groups were formed from sows on the 80th day of pregnancy (group 1, n=5), after farrowing (group 2, n=5) and before weaning piglets (group 3, n=5). The Vet ABCTM analyzer (Horiba Medical Poland) was used. Counting of reticulocytes by “supravital staining” with a solution of “brilliant cresyl blue”. Statistical processing in the Microsoft Excel program (Data Analysis package), evaluation of the reliability of differences based on the Mann—Whitney U criterion. As a result, it was found that the average volume of red blood cells increases with a decrease in their number and hemoglobin concentration, which is quite natural and indicates a regenerative response with the appearance of reticulocytes in the blood. The correlation coefficient between erythrocytes and the average volume of erythrocytes was r=-0.53 (r2=0.28, p=0.01), between the average volume of erythrocytes and reticulocytes r=-0.50 (r2=0.25, p=0.05). There were no significant differences among the groups in reticulocytes and the average volume of erythrocytes. The dynamics and intensity of regeneration are moderate in all three groups.

Распространенность гельминтозов среди сельского населения Хабаровского края

The large medical and socio-economic burden of helminth infections provides the basis for studying the frequency and type of helminth infections among the population of residents of the Russian Far East and is relevant. The purpose of this study was to study the prevalence and type of parasitosis among different age groups of the rural population of the Lazo District. The study was carried out in the design of a retrospective cohort non-randomized continuous study. On the basis of the District Hospital of the Lazo District, 26,483 medical records were processed and analyzed among the adult and child population for the period 2013–2023, with the study of data on the incidence of parasitosis in the rural population based on the results of a microscopic examination of feces for helminth eggs and protozoan cysts ( by Kato method). Statistical analysis was carried out in the STATISTICA 16.0 program, as well as the use of statistical functions of the EXCEL program, using nonparametric data processing methods. After a parasitological survey carried out in 2013–2023, it was revealed that the largest proportion among the infested were children, predominantly in the age group of 4–7 years. There were no significant differences by gender. Based on the set of indicators that determine the structure and dynamics of epidemiological processes in the Lazo District, clonorchiasis (0.07 %, 19 people), ascariasis (0.90 %, 238 people), enterobiasis (1.90 %, 503 people) were diagnostically significant. people), as well as giardiasis (2.00 %, 530 people). There is a need for improved diagnostic tools and effective control options to scale up public health interventions and improve clinical detection and treatment of helminth infections in the Russian Far East.

Suggested Scenarios of Initial Filling for the Badush Reservoir, Iraq

This study developed hypotheses based on the geometric analysis of the Badush Dam reservoir to simulate the initial filling and operation of the dam reservoir. A mathematical equation was developed to estimate the daily demand for water behind the dam, and then build an EXCEL program for calculating the input demand, output discharges, and the storage difference for the dam reservoir. Conditions and parameters for continuous/rapid filling and others for gradual filling of the reservoir were arranged in the program. The daily input discharges records, demand, and output discharges produced for the two wet and dry years selected from the records released from Mosul dam to implement the scenarios of rapid and gradual filling of Badush reservoir. The results showed that the reservoir could be filled within 20 or 130 days, according to the continuous (rapid) filling program in the wet or dry years, respectively, and the possibility of filling the reservoir within 133 or 258 days, according to the gradual filling program in the same two wet or dry years, respectively. The operation was more flexible in the dry year than the wet because the wet years may have high daily discharge releases from Mosul Dam, which requires careful monitoring of the Badush reservoir levels. After all, it may rise in a critical period and needs quick intervention by the operator. In rapid filling, it was noted that the daily increase during the days of storage in a wet year was about 1-2 m/day while no more than 1 m/day for the dry year. Regarding the gradual filling, the daily increase during the days of storage in the wet year varied between 1-3 m/day on some days that do not coincide with the peak flood wave. In the second stage, which lasted only two days, the level rose between 3-4 m/day. The third stage, which lasted only one day and coincided with the peak flood, was accompanied by a sharper increase in the level, reaching 7 m/day. The daily level increased from a few centimeters to 2 m/day through the gradual filling in the dry year.

Liver Transplantation Research from India During the Last 25 Years: 1998–2022

Liver transplant surgery has been performed in India for the last 25 years. We aimed to analyse the trends, characteristics, and key elements in the field of liver transplantation research from India. On April 23, 2023, we conducted a search of the Scopus database for the literature on liver transplantation research, using a well-defined search strategy. MS Excel and VOS viewersoftware programs were used to examine the articles for organisation, author, journal, keywords, and high-cited literature. This analysis examined a total of 556 papers, which constituted only a 1.55% share of the global output. These papers involved 442 organizations, 1575 authors, and 147 journals. External funding was received in 4.13% and 23.56% were involved in international collaboration. Three Delhi-NCR organizations, namely the Medanta-The Medicity (n=63), Institute of Liver & Biliary Sciences (n=60), and Indraprastha Apollo Hospital (n=48) led in publication productivity. M. Rela (n=90) and A.S. Soin (n=63) were the leading authors in publication productivity, while S. Sudhindran and P. Bhangui were the most impactful authors. Liver Transplantation (n=96) and Journal of Clinical & Experimental Hepatology (n=65) published the maximum number of these papers, whereas, Annals of Surgery and Journal of Hepatology led in the citation impact per paper. The most significant keywords were "Liver Transplantation" (n=484), and "Living Donor" (n=254). Only 1.80% (n=10) of the papers were highly cited papers that received 50 to 142 citations and they together registered 69.9 citations per paper. Although the number of publications on liver transplantation from India started growing recently, it forms only 1.55% of the global report. There is an unmet need to increase government-supported research and multicenter collaborative studies at national and international levels for high-quality patient care.

Risk assessment and hygienic regulation of using of milbenock insecticide based on the new active substances aversectin class milbemectin

Annotation. The problem of risk assessment for the population and persons involved in the treatment of agricultural crops with plant protection products is relevant in many countries of the world. The aim of the study was hygienic regulation of the Milbenok insecticide based on a new compound of the active substances aversectin class milbemectin to reduce the potential occupational risk and population risk. The method of natural experiment was used, residual amounts of milbemectin were determined by the method of high-performance liquid chromatography. Statistical processing of the obtained results, mathematical modeling of the degradation of the milbemectin was performed using EU recommendations and MS Excel programs (2000) and IBM SPSS Statistics Base v.22. It was determined that the half-life (DT50) of milbemectin in the soil in Ukraine climate regions – 21.4±1.6 days, in agricultural crops (apples, grapes) – 11.8±0.6 days. Risk assessment of the population based on the possible daily intake of the pesticide with products, as well as the integral indicator of danger when consuming products grown treated by insecticide Milbenok showed that the risk is two level lower than the permissible level and is moderately dangerous. The working zone is relatively safe for workers when using the insecticide. The risk for persons involved in the application of the Milbenok on apple trees, considering the contamination of personal protective equipment, was acceptable. The MRL of milbemectin was substantiated in apples, grapes (berries) – 0.02 mg/kg, apples, grapes (juice) – 0.01 mg/kg, AAC in the soil – 0.2 mg/kg and the regulations for the safe using of the Milbenok (pre harvest interval and time of workers' exit to cultivated areas). The obtained results should be considered when deciding the need to control pesticide residues in food products and environmental objects.

Distribution of Blue Swim Crab (Portunus pelagicus) Catching Areas Using Foldable Traps in the Coastal Waters of Barru Regency, Indonesia

The utilization of blue swim crab resources poses a significant challenge that requires appropriate solutions, thus necessitating effective resource management. Uncontrolled fishing conditions can lead to economic overfishing if proper management is not implemented. Moreover, fishermen compete to increase their fishing efforts, leading to the need for capturing in more distant areas. Therefore, rehabilitation and management actions need to be promptly executed. This study aims to analyze blue swim crab catching areas based on distance from the coast, crab weight, carapace width, size of adult crabs, and the size of crabs eligible for capture in the coastal waters of Barru Regency. The research was conducted over 8 months, from May to December 2022, in the blue swim crab fishing grounds in the waters of Barru Regency, South Sulawesi Province. Data Was collected through a combination of survey and observation methods. The collected data were descriptively analyzed SPSS and Microsoft Excel programs. The results indicate that: (1) Constituted 51.8% of the captured individuals, and females constituted the remaining 48.2%; (2) The average weight and carapace width of these crabs fluctuated based on the distance and depth of the fishing areas; (3) A higher number of adult-sized crabs were caught in the crab catching areas at a distance of 3-5 nautical miles from the coast; (4) The percentage of adult crabs was larger compared to crabs eligible for capture, indicating symptoms of overfishing; (5) All the individuals were of mature size. Specifically, 88.9% for male crabs and 94.3% for female crabs. The criteria used to determine eligibility for capture were carapace width above 11 cm.

Utilizing Respondent Driven Sampling to assess neurocognitive functioning in the indigenous American Samoa population 60 years or older.

AbstractBackgroundRespondent Driven Sampling (RDS) is a cost‐efficient, chain referral sampling method, where respondent seeds recruit others who are eligible within their social networks; those recruited by the seeds then recruit others (Heckathorn, 1997). In American Samoa recruitment of a random population‐based sample is difficult due to systematic error and biases in sample characteristics arising from the hierarchical relationships prominent in American Samoan society (Aitaoto, et al. 2007; Cassel 2010; Cassel, 2014). The INdigenous Samoan Partnership to Initiate Research Excellence (INSPIRE) program recruited 718 participants age 45 and over during a 51‐day period with 20% age 60 or higher. For this reason, RDS methods were utilized to assess neurocognitive functioning in the Samoan population age 60 or over.MethodINSPIRE program staff recruited 60 participants as RDS seeds (30 men and 30 women). Once the seeds completed the data collection process, they were given coupons to recruit a maximum of 3 community members. In addition, they were provided a printed reminder of the eligibility criteria. The patterned continued to create consecutive recruitment waves (Wave 1, n = 60; Wave 2, n = 180; Wave 3, n = 540) until the sample size was reached. Participants received a total $25 incentive for participating in the survey. Additionally, participants will be compensated as RDS recruiters and receive an additional $15 for each recruit who participates, up to a maximum of 3. The RDS recruitment proposed to yield 780 participants, with 390 women and 390 men with a 12% loss to follow up.ResultPreliminary data analysis reveals target sample size was collected in 126 days (41% Male, 59% Female). Referral chain analysis reports only 25% of seeds recruited 80% of participants although social networking sizes varied for the seeds. Some participants with higher social networks did not participate in recruiting.ConclusionIntercept promotions complimented the use of RDS to help identify seeds and include faith‐based institutions (churches), senior centers, civics clubs, village‐based and other networks to recruit men and women, ages 60 and over. Maintaining a central location for study implementation and coupon payment supported ease of access for the study population.
