В большинстве известных феноменологических моделей деформирования сплавов с памятью формы предлагаются определяющие соотношения, выражающие приращения фазово-структурных деформаций через приращения напряжений, температуры, параметра фазового состава и сами величины напряжений, деформаций, температуры и параметра фазового состава. Сами значения напряжений, деформаций и температуры входят в правые части этих соотношений достаточно сложным, существенно нелинейным образом. Зависимость параметра фазового состава от температуры и девиатора напряжений является также существенно нелинейной, причем эта нелинейность не подчиняется частному постулату изотропии А.А. Ильюшина, т.е. наблюдается зависимость не только от интенсивности напряжений, но и от третьего инварианта девиатора напряжений. Процедуры численного решения краевых задач о деформировании элементов конструкций из сплавов с памятью формы методом конечных элементов требуют построения скоростной матрицы жесткости. Для этого необходимо иметь явные выражения приращений компонент тензора напряжений через приращения компонент деформаций, приращения температуры и сами величины напряжений, деформаций, температуры и параметра фазового состава. Таким образом, требуется построить обращение известных определяющих соотношений, получаемых в рамках феноменологических моделей деформирования сплавов с памятью формы. Построение такого обращения осложняется наличием существенно нелинейной зависимости параметра фазового состава от второго и третьего инвариантов девиатора напряжений. В работе изложена методика аналитического получения такого обращения. Приведены результаты численного решения задачи о прямом превращении в толстостенной цилиндрической оболочки, находящейся под действием постоянного внутреннего давления в предположениях о линейной и билинейной зависимости материальных параметров от параметра вида напряженного состояния.

Published: August 2024

Purpose. To determine the patterns of changes in the gas mixture parameters in the final gas-drainage pipeline section during draining-out of gases from the mined-out space through the gas pipeline branches with impaired throughput capacity. Methodology. Theoretical studies of gas mixture flows in mine gas-drainage pipelines, as well as the laws of gas dynamics and hydromechanics are used to solve the task set. Findings. It has been revealed that the methane concentration remains constant in the section of the gas-drainage pipeline, which is located in an uncontrolled ventilation working area. In this case, methane concentration decreases in the gas-drainage pipeline behind the insulating jumper in the zone influenced by the outlet ventilation jet. It has been found that the reduced hydraulic diameter of the gas pipeline contaminated branch leads to an increase in the absolute gas mixture pressure, a decrease in its flow rate and methane yield in the final gas-drainage pipeline section. By solving quadratic regression equations, the ratios linking the hydraulic diameter of the gas pipeline contaminated branch with the gas mixture parameters in the final gas-drainage pipeline section have been obtained. Originality. A relationship between the hydraulic diameter of the gas pipeline contaminated branch, draining-out the gas mixture from the mined-out space, and the gas mixture parameters in the final gas-drainage pipeline section has been revealed. Practical value. The obtained ratios for the hydraulic diameter of the gas pipeline contaminated branch make it possible to estimate its throughput capacity and, by the time new branches are set, if necessary, increase the discharge in the gas-drainage pipeline to maintain the necessary degasification efficiency.

Published: August 2024

Purpose. To increase the efficiency of drying lines for bulk products by automating control using intelligent technology to determine the state of the product and predict its initial moisture content by analyzing a series of control signals and messages in the time domain. Methodology. The author’s model of a drum dryer with axial and furnace burners for drying charge used for the production of iron ore concentrate – pellets – was used. The model was used to generate training and control examples. The performance of the multi-agent technology and the accuracy of predicting the initial moisture content were researched. Findings. The article analyses the factors that complicate the high-quality automatic control of the process of drying bulk products in drum dryers rotating in a furnace with burners. A model of an intelligent predictor is proposed, which identifies the state of the product and predicts its output moisture content on the basis of available control and feedback signals. The operability of the multi-agent system model and of the calculating algorithms for the predicted moisture value was proved. The possibility of using the technology to ensure automatic control of the technological process and high-quality stabilization of the controlled parameter are demonstrated. Originality. The predictor is implemented as a peer-to-peer multi-agent system. This multi-agent system stores and works signal vectors with values placed by the time delays between the change in the corresponding signal and the change in product moisture at the dryer outlet. Each agent contains a description of a specific situation in the dynamics. The technology provides for automatic adjustment of the multi-agent system by analyzing arrays of signals over a long time period and generating new agents in cases where a situation is detected which cannot be described by an array of existing agents. Practical value. The technology provides the initial moisture content calculation by an array of agents and allows the dryer automatic control by levelling the time delay in the feedback channel.

Published: August 2024

Background: In addition to individuals with elevated androgen levels, female pattern hair loss is also reported in women without elevated androgen levels. In recent years, vitamin D and ferritin levels have been taken into account while treating these individuals.Women who have female-pattern hair loss may also suffer from vitamin D and iron deficiencies. This research is to determine the roles that ferritin and vitamin D play in the etiopathogenesis of hair loss. Materials and methods: A cross-sectional study was conducted in Delta Medical College and Hospital among the 50 female patients aged between 12-58 years. Results: According to the findings of our research, a total of 89% of the female patients had blood vit-D levels that were both deficient and insufficient level, which indicates that deficiency of Vit-D can enhance the hair loss in female patients. Also, the ferritin value was quite deficient in range among the participants. Conclusion: This study had a small sample size, was conducted in just one site, and didn't use a standardized method to examine the dietary intake of FPHL patients. For this reason, it is recommended that, in addition to other hormonal tests, blood D3 levels and other mineral tests be analyzed to assess a patient's health.

Published: August 2024

Background: Antimicrobial Resistance (AMR) posses a complex threat to global health security and universal health coverage. Gram negative bacteria have developed the broadest spectrum of resistance due to multiple structural adaptions and antibiotic degradation enzymes including Extended Spectrum Beta Lactamase, AmpC Cephalosporinase and Carbapenemase. Carbapenemases are beta-lactamases with versatile hydrolytic capacities. They have the ability to hydrolyze penicillins, cephalosporins, monobactam, and carbapenems. The classical phenotypic method cannot provide an efficient means of diagnosis of the carbapenemase producer. Multiplex PCR also helps in simultaneous detection of various genes, reducing materials, manpower and helps in determining epidemiology related to these genes and infection subsidence. This study was designed to determine the presence of carbapenemase producers among the carbapenem resistant uropathogens and to compare the phenotypic method with genotypic method along with the antimicrobial resistance patterns.
Materials and methods: This cross-sectional study was carried out in the Department of Microbiology Chittagong Medical College, Chattogram for quantitative culture, mCIM test, and multiplex PCR for carbapenemase producers. A total 68 Gram negative uropathogens were isolated and identified by conventional methods. Antibiotic susceptibility test was performed by disk-diffusion technique. Carbapenemase producers were detected phenotypically by modified carbapenem inactivation method among the meropenem resistant isolates. Gene encoding bla NDM and coexistence of bla NDM +bal OXA-48 were identified by multiplex PCR.
Results: Twenty (29.41%) meropenem resistant strains were detected among 68 Gram-negative uropathogens. The most common isolates were Escherichia coli and Pseudomonas spp. Among 20 meropenem resistant strains, 19(95%) carbapenemase producers were detected by multiplex PCR, 17(85%) by modified carbapenem inactivation method. The most prevalent gene was blaNDM (94.73%). More than one carbapenemase gene was present in one (5.6%) isolate. Overall, carbapenemase encoding genes were detected in 11.11% of the studied Gram negative uropathogenes. All of the carbapenemase producing organisms were 100% resistant to Ampicillin, Cefuroxime, Ceftriaxone, Ceftazidime, Aztreonam, 94.73% to both Cotrimoxazole and Nitrofurantoin, 68.42% to PipercillinTazobactam and 63.15%, to Amikacin.
Conclusion: The study shows that rapid dissemination of blaNDM in Bangladesh demands the effective measures along with antibiotics policies in hospitals which combat the spread of this strains.

Solar energy is one of the New Renewable Energy (EBT) which is used specifically to meet electrical energy needs by converting it using a device often called a solar panel. Solar panels are generally arranged in PLTS in open areas so they have the potential to be exposed to dirt such as dust which can accumulate over a certain time and cause a reduction in the efficiency of sunlight irradiance on the surface of the solar panels. The solar panel cleaning system in solar power plants (PLTS) usually still uses conventional methods, namely cleaning by human power. In current technological developments, many automatic cleaning tools have been developed, but most of them in the field are only able to support a tool mass of under 10 kg. To clean a large 330 Wp solar panel, a frame construction is needed as a panel holder that can support a device mass of more than 10 kg, so in this paper a solar panel frame is designed that can support a weight of up to 40 kg. This tool is designed with a mechanical system that is able to support a larger mass of tools than is generally available in the field. In terms of mechanical system, the frame design of this tool uses a rectangular shape with hollow iron material to maintain a balanced position and is driven by a motor with a pully system as a kinetic energy transmission system for rotational motion using a High Torque motor. From the research results, it was found that the tool was able to work with a mass of 40 kg, a power consumption of 53.15 Watts with a tool operating time of 4 hours.

The problem that often occurs is that many users use unsafe devices to carry out the login process, for example using laptops, mobile phones and other devices in public spaces such as terminals, airport stations, public libraries, cafes and even internet cafes. One of the important steps in the security and authentication process. This verification ensures that the account owner has access to the email address used to register or log in to a service. Multi-Factor Authentication (MFA) is a security method that requires users to provide more than one form of authentication to access a system or application. Research focuses on evaluating the security of MFA, using appropriate metrics (such as authentication success rate, successful attack rate, or discovered vulnerabilities) to assess the effectiveness of MFA. Implementing MFA on email accounts is not only a wise security measure, but also a recommended practice to protect personal information and reduce online security risks
Preservice Teacher’s Attitude Toward Problem-Solving in Mathematics Education
Authors: Mohammed Atar Alphaa
Published: August 2024

This study delved into the attitudes of 90 level 300 preservice teachers towards problem-solving in mathematics education, recognising its significance in enhancing students’ mathematical proficiency. Conducted through a cross-sectional survey design, the research encompassed preservice teachers from various specialities, including Junior High School, Upper Primary, and Early Grades in a college of education in the Upper West Region of Ghana. Utilising a structured questionnaire, rate their agreement or disagreement with the 27-item attitudinal scale on a four-point scale, ranging from 1 (strongly disagree) to 4 (strongly agree). The scores were interpreted as follows: a score of one represents the lowest possible level, indicating a negative attitude, while a score of five represents the highest possible level, indicating an assertive positive attitude. The attitude scores had a standard deviation of 5.19085, suggesting moderate variability from the mean. The attitude ratings displayed a negative skewness of -0.967, indicating that most preservice teachers had predominantly favourable attitudes towards problem-solving as a teaching method. Notably, the research found no significant differences in attitudes between male and female preservice teachers, nor across different programs of study, indicating the need to consider additional factors influencing attitudes towards problem-solving in mathematics education. The lack of significant differences in attitudes based on gender or program of study suggests that factors beyond these demographic variables may influence preservice teachers’ perceptions of problem-solving

Authors: Andyanita Hanif Hermawati  , Aesthetica Aesthetica Islamy
Published: August 2024

Abstract. The prevalence of Escherichia coli resistance in Indonesia to antibiotics is 43%. This is a serious problem because it can reduce the efficiency and effectiveness of treatment. Therefore, new products with high antibiotic potential are needed, one of which is telang flower. Telang flowers have active substances with the ability to inhibit bacterial activity. This study aims to test the antibacterial potential of telang flower (Clitoria ternatea) by maceration using 96% ethanol solvent. The research design was an experiment with a control group. The antibacterial testing method used was the agar diffusion method with three repetitions. The telang flower (Clitoria ternatea) extracts used were 50% and 100%. Data were obtained in the form of inhibition zone diameter data. The data were analyzed univariately and bivariate, namely comparing the diameter of the inhibition zone produced from each concentration with the diameter of the inhibition zone of positive and negative controls and bivariate using ANOVA. The results of this study showed that the average diameter of the inhibition zone produced was 15.28 mm (50% concentration) and 19.68 mm (100% concentration). The results of the bivariate analysis showed a p-value = 0.000. This indicates that there is a difference in the diameter of the inhibition zone in all treatment groups. The recommendation from the results of this study is that telang flower extract (Clitoria ternatea) can be continued in vivo research to identify its potential as an alternative antibacterial drug.

Abstract. Osteoarthritis (OA) is a degenerative joint disease characterized by damage to joint cartilage, subchondral bone, and osteophyte formation. The prevalence of OA is still large with major therapy is non steroid anti inflammatori (NSAID) drug. However, prolonged use of NSAIDs leads to side effects on gastrointestinal tract. Zingiber officinale var. amarum is beneficial herbal for anti-inflammatory therapy in OA. The damage of chondrocytes in OA triggers the activation of inflammatory process through the COX-2 pathway, resulting in the production of chemical mediators prostaglandin D2 (PGD2) and thromboxane A2 (TXA2), causing pain and functional decline. Thus, this research aimed to predict active compounds of Z. officinale var. amarum rhizomes that potential to inhibit PGD2 and TXA2 as anti-inflammatory agents for OA through molecular docking. Method This research use 20 active compounds of Z. officinale var. amarum using molecular docking method with proteins target including of PGD2 (ID:1S2A) and TXA2 (ID:6IIV). The docking process was conducted using the PyRX
0.8 application, and the results were visualized in the BIOVIA Discovery Studio 2020 application. Result the research on the 20 active compounds in the rhizome of Z. officinale var. amarum indicates that compounds such as [6]-Gingerdiol 3,5-diacetate, 10-gingerol, gingerdione, and gingerdiol can interact with the active site of the protein 1S2A through hydrogen bonding with Gln-222. Furthermore, compounds like [6]- dehydrogingerdione, paradol, gingerdiol, geraniol, 10-gingerol, gingerdione, [6]- Gingerdiol 3,5-diacetate, isoborneol, zingerone have been identified to interact with 6IIV through hydrogen bonding with Gln-301 and Thr-81. This indicates that these compounds exhibit activity as inhibitors of PGD2 and TXA2. The interactions occurring between the complex compounds of Z. officinale var. amarum and 1S2A and 6IIV can lead to inhibitory effects on PGD2 and TXA2.

Likewise with the Islamic religion which was passed down in the midst of Arab society which has customs and traditions passed down from generation to generation. The patterns adopted by Islam in responding to Arab customs during the process of forming Islamic law can also be used as a guide in adapting adat to Islamic law elsewhere. Even though Islamic law is in a fixed form, it does not mean that Islamic law refuses flexibility in dealing with the customs and habits of a place. Tradition is part of culture. One of the local traditions that is closely attached to the life of Indonesian people, especially Gorontalo, is the process of carrying out the beati ceremony.

When the availability of iron is insufficient to meet the needs of the body with or without anemia, it is classified as iron deficiency characterized by a serum ferritin concentration of less than 100 ng/ml or a 100-299 ng/mL with a transferrin saturation (TSAT) less than 20% in patients with heart failure. Reduced intake, low iron absorption due to increased hepcidin secretion, iron secretion in the reticuloendothelial system as a result of inflammation, and blood loss from the gastrointestinal system are mechanisms believed to cause iron deficiency (ID). With 25–42% of Heart Failure (HF) patients having ID when anaemia is absent, ID is frequent regardless of the presence of anaemia in HF. ID management in HF requires a shift in the therapeutic focus from dealing with anemia to iron supplementation, both oral and intravenous (IV). Current guidelines also support the use of IV iron. New drugs also focus on iron metabolism, which these drugs are still in development.
