Closing lemmas for interval translation maps
Authors:   St. Petersburg State University, Krivovicheva Anna D.
Published: May 2024

A interval translation mapping (or a circle translation mapping) is studied. Such maps can be regarded as interval exchange maps with overlaps. It is known that for any mapping of that type admits a Borel probability invariant non-atomic measure. This measure can be constructed as a weak limit of invariant measures of maps with periodic parameters. Those measures, are just normalized Lebesgue ones on a family of sub-sectors. For such limit measures, in the case of a shift of the arcs of the circle, it is shown that any point of their supports can be made periodic by arbitrarily small change of the parameters of the system without changing the number of segments. For any invariant measure, it is deduced from Poincar´es Recurrence Theorem shows every point can be made periodic by a small change in the parameters of the system, with the number of intervals increasing by two at most.

Published: May 2024

An inverse problem is considered, which consists in finding a solution and a one-dimensional kernel of the integral term of an inhomogeneous integro-differential equation of hyperbolic type from the conditions that make up the direct problem and some additional condition. First, the direct problem is investigated, while the kernel of the integral term is assumed to be known. By integrating over the characteristics, the given intego-differential equation is reduced to a Volterra integral equation of the second kind and is solved by the method of successive approximations. Further, using additional information about the solution of the direct problem, we obtain an integral equation with respect to the kernel of the integral k(t), of the integral term. Thus, the problem is reduced to solving a system of integral equations of the Volterra type of the second kind. The resulting system is written as an operator equation. To prove the global, unique solvability of this problem, the method of contraction mappings in the space of continuous functions with weighted norms is used. And also the theorem of conditional stability of the solution of the inverse problem is proved, while the method of estimating integrals and Gronoullo’s inequality is used.
Differences in sum-of-hourly and daily reference evapotranspiration for a rice–wheat cropping system in Ganga Basin, India
Authors: Yetbarek Ephrem , Vashishth Nirali , Ojha Richa
Published: May 2024

Estimating reference evapotranspiration (ETo) at 24 h timesteps has been considered sufficiently accurate for a long time. However, recent advances in weather data acquisition have made it feasible to apply hourly procedures in ETo computation. Hourly timesteps can improve the accuracy of ETo estimates, as data averaged daily may misrepresent evaporative power during parts of the day. This study investigates the differences between daily ETo computations performed at 24 h (ETo,d) and sum of hourly (ETo,h) for rice–wheat cropping systems in the Ganga Basin, India. The meteorological data were collected from an automatic weather station located in an experimental plot at IIT Kanpur, India. Daily and sum-of-hourly ETo computations were performed according to the FAO-PM equation for rice and wheat cropping seasons. Diurnal variations of meteorological variables resulted in an underestimation of ETo when the daily timestep was considered. No significant difference was observed during wet periods. The sum-of-hourly estimates of ETo were able to capture the abrupt changes in climate variables, while the daily ETo failed to represent it as it considered the average values only. As a result, the sums of hourly ETo estimates are more reliable in the Ganga Plains.

Published: May 2024

The effect of chemical oxygen demand (COD)/N ratio and sludge retention time (SRT) on the simultaneous nitrification and denitrification (SND) process in aerated moving-bed sequencing batch reactor (A-MBSBR), for treating synthetic municipal wastewater, was studied. Three lab-scale reactors with SRTs of 5, 10, and 15 days were operated under COD/N ratios of 10 (phase1) and 20 (phase2). The high correlation coefficients between nitrification and denitrification efficiencies in both phases demonstrated that the denitrification efficiency in A-MBSBRs was strongly affected by nitrification efficiency (nitrate concentration). The high COD/N ratio of 20 in phase2 led to weaker nitrification (29.6–39.1%) and consequently weaker denitrification (15.8–27.9%) under all SRTs, compared with nitrification and denitrification efficiencies (44.4–62.7% and 26.3–42.8%) in phase1 with COD/N ratio of 10. This was most probably due to a better balance between the population of heterotrophs and autotrophs in phase1. In phase2, increasing SRT from 5 to 15 days was beneficial for both nitrification and denitrification reactions. Therefore, the optimal SND efficiency in phase2 was expected to be achieved under SRTs higher than 15 days. In phase1, the highest and the lowest nitrification and denitrification efficiencies were obtained at SRTs of 10 and 5 days, respectively.
Individual and Collective Approaches of Students who are Members of Social Clubs at University to Mitigate Climate Change Impacts
Authors: Köçer Musab Süleyman
Published: May 2024

Climate change is one of the most important global problems of our time. For the solution of this problem, the need for awareness and taking responsibility at individual and social level is quite high. The aim of this study, which was conducted on social club members, is to examine the level of hope for the prevention of climate change according to sociodemographic characteristics, club factors and taking responsibility variable. Relational survey model, one of the quantitative research methods, was used in the study. The research data were collected from the students studying at Ardahan University in the 2023-2024 academic year through a questionnaire. The data obtained were analyzed using SPSS 27 and AMOS 24 statistical package programs. In this context, parametric tests such as Independent Samples T Test, One- Way Analysis of Variance (ANOVA), Pearson Correlation and Simple Linear Regression Analysis were applied due to the normal distribution of the data. When the results of the analysis are examined, it is seen that the mean scale scores of the sample group are high; there is a significant difference between the groups in terms of hope levels according to their education levels and club types; and the variable of taking responsibility has an effect of 26.7% on the level of hope. Thus, a one-unit increase in the level of responsibility causes a 0.301-unit increase in the level of hope for preventing climate change. In this context, club members' approaches to preventing climate change can be strengthened by conducting incentive studies to increase their sense of responsibility.

Authors: Rasyid Al , Chandra Julia Remi , Harris Salim , Kurniawan Mohammad , Hidayat Rakhmad , Yamin Muhammad , Wiyarta Elvan
Published: May 2024

Background

Blood viscosity has received increased attention as a potential predictor of ischemic stroke risk, particularly in patients with chronic heart failure (CHF). Despite the importance of this link, there has been a notable paucity of comprehensive research on the subject. Hence, the major goal of this study was to shed light on the potential importance of blood viscosity in individuals with ischemic stroke and CHF.

Case Presentation

An 85-year-old male was presented to the emergency department after three days of gradually decreasing consciousness. His medical history included hypertension and CHF. His Glasgow Coma Scale (GCS) was determined to be E2M5V3, and he displayed evidence of upper motor neuron facial palsy as well as right hemiparesis. The clinical assessment scores, which included the NIHSS and mRS, were 10 and 4, respectively. MRI imaging confirmed the existence of several acute infarctions. Other diagnostic procedures, including an x-ray, revealed cardiomegaly and echocardiographic findings were compatible with grade I diastolic dysfunction. His blood viscosity was 8.19 cP, which was much higher than normal. The patient was diagnosed with ischemic stroke, CHF, and hyperviscosity based on these findings. Despite a small increase in blood viscosity to 8.16 cP after a six-day treatment session, the patient showed significant clinical improvement. Unfortunately, he was readmitted immediately after being discharged and died three days later.

Conclusion

This case demonstrates the importance of blood viscosity in the evaluation and prognosis of patients with ischemic stroke and CHF.

Background: Propofol is a non-opioid intravenous anesthetic agent and it is most commonly used for induction of anesthesia but it has a consistent side-effect of pain when it is injected intravenously. Aim of our study was to compare lignocaine and ondansetron for attenuation of pain on propofol injection in laparoscopic cholecystectomy. Methods: 100 patients planned for laparoscopic cholecystectomy were enrolled for this comparative randomized study. Group L (Lignocaine) – Patients received Inj. Lignocaine 0.5 mg/kg 1 minute before inducing with injection propofol. Group O (Ondansetron) – Patients received Inj. Ondansetron 0.1mg/kg 1 minute before inducing with injection propofol. The patient was evaluated for pain during injection using a four-point scale of 5 seconds and 15 seconds after the propofol injection. Chi-squared test, Fisher’s exact test, and Mann-Whitney test were used for data analysis. Result: Demographic data in group L and group O were similar. The mean± SD pain score during the first 5 seconds in group O was 0.38 ± 0.57 while in group L was 0.02 ± 0.14 (p<0.001). The mean± SD post-operative nausea and vomiting (PONV) score during the first hour in group O was 0.08 ± 0.27 while in group L was 1.96 ± 1.160 (p<0.001). Conclusion: We concluded that lignocaine was found more effective than ondansetron for attenuation of propofol-induced pain and post-operative nausea vomiting was much lower than by ondansetron as compared to lignocaine.

Background: Blockbuster Laryngeal mask airway (LMA) is a device gaining popularity in airway management, and advantageous in ventilation and intubation. Air Q LMA is a supraglottic airway device with a shorter and wider breathing tube designed for ventilation as well as intubation in difficult airway. We aimed to evaluate the success of tracheal intubation using these devices. Methods: Overall 80 participants aged 18-60 years with ASA I and II were randomized into Group A (Air Q LMA) and Group B (Blockbuster LMA) using computer generated random numbers. The objectives of our study were to evaluate first pass successful intubation, ease, time and attempts taken for device insertion, oropharyngeal leak pressure, time for LMA removal and post operative complications. Association between variables were assessed with chi square test and unpaired t test. Result: There was a statistically significant difference in the first pass successful intubation between the groups which was higher in Group B (90%) than Group A (60%) (P<0.001), the overall successful intubation was more in Group B 97.5% compared to Group A 85%. The device insertion was easy in 85% patients in Group A and 95% patients in Group B. The time taken for introduction of Air Q was longer (38.15±4.92sec) when compared with blockbuster LMA (26.25±4.44sec), (P<0.001). Mean Oropharyngeal leak pressure of blockbuster LMA (32.40±3.99cmH2O) was greater than Air Q LMA (29.10±2.61cmH2O), (P<0.001). Conclusion: Blockbuster LMA provides greater success of blind tracheal intubation when compared to air Q LMA.

Published: May 2024

Background: Failure of neuraxial or regional anaesthesia can result from factors such as drug errors, technical inefficiencies, and poor patient positioning. While these causes are well-known, resistance to local anaesthetic action due to mutations in sodium channels or scorpion sting is a lesser-known contributor to block failure. In India, a tropical country with a significant number of patients presenting for surgical procedures, a history of scorpion bites is not uncommon. Case: We observed seven cases of failed regional anesthesia who had history of scorpion sting. All the patients received intrathecal bupivacaine by experienced anesthesiologists, of seven patients five patients did not develop sensory or motor block. One patient had delayed successful subarachnoid block after second attempt and one patient had successful block at first attempt. Conclusion: Our observations revealed instances of failed spinal blocks, despite adequate drug dosages and experienced anesthesiologists performing the procedures, in patients with a history of scorpion envenomation. Accordingly, our study concludes that obtaining a thorough scorpion sting history during pre-anesthesia check-ups, particularly in endemic areas, can effectively prevent unnecessary repeated pinpricks, escalating dosages, patient and surgeon discomfort, and skepticism towards the skills of anesthesiologists.

Published: May 2024

Background: Chronic lower back pain is a common cause of disability. Opioids, although not first-line treatment, are often prescribed for chronic lower back pain. The purpose of this study is to understand the perceptions of opioids among the rural Guatemalan population for chronic low back pain to best optimize a shared decision-making process in pain management. Methods: Participants were given a survey regarding demographic information, whether they were offered an opioid prescription for chronic lower back pain, and whether they would take the medication if offered. Participants completed the Prescription Opioid Overdose Knowledge Score (Rx-OOKS) questionnaire, to evaluate knowledge of opioid overdose. Result: The survey results showed that 93.3% of participants were never offered an opioid prescription for chronic low back pain by a provider in Guatemala. However, a majority would have taken an opioid if given the opportunity. Scores on the Rx-OOKS revealed a statistically significant lower mean (p< 0.05) than the United States’ study baseline for the knowledge of signs of prescription opioid overdose construct, actions to take in the opioid overdose construct, and total score construct. Conclusion: This research study was able to show that although there is a low prevalence of opioid use in rural Guatemala and decreased knowledge of opioid overdose. Thus, physicians and other healthcare providers must do their due diligence to educate their communities about opioid use, opioid overdose, and naloxone use for a potential overdose. This process is essential in the development of a shared decision-making process for pain management.

Published: May 2024

Many natural resources from agricultural waste are used as inhibitors, one of which is Durio zibethinus. The systematization of the electrochemical experiment and morphology characterization were performed to analyse the corrosion inhibitor characteristics. The adsorption was calculated to help further understand the inhibition mechanism. The electrochemical results showed that the inhibitor extract acted as a cathodic type, with inhibition efficiency up to 75.05% using the method of PDP and 64.69% using the method of EIS. Based on the investigation of corrosion inhibitors, the adsorption isotherm agreed with the experimental results. The  EIS data confirmed the chemical reaction and physical adsorption processes of the multi-component corrosion of DZE inhibitor. The results revealed the potential use of DZE inhibitors in applications such as desalination plants. Further, the improvement in performance was conducted through the use of synergy effects.

Published: May 2024

Hydroxiteapatie (HA) as a filler is a mixture that is often added to alloy or composite products. This study investigates the development of polyester composites reinforced with kenaf fiber (KF) and hydroxiteapatite (HA) fillers in order to reduce their environmental impact. The strength, decomposability, and low weight of these composites make them ideal for a wide range of applications due to their exceptional mechanical properties. In addition to tensile and bending tests, water absorption tests, and immersion in seawater simulations, the composites were evaluated under demanding conditions. The water absorption rate increased with increasing fiber volume percentages in the composite, primarily due to the water-absorbing properties of the KF and HA particles. In contrast, the KF-15%HA-reinforced composite, which underwent soaking at 50 °C, exhibited the lowest tensile strength of the three composites. Additionally, the temperature at which aging occurs influences the composite's ability to absorb water and its mechanical properties. A filler may improve the mechanical properties of composites made from kenaf fibers, and it can also affect moisture absorption, reducing moisture absorption and increasing adhesion.

Published: May 2024

Geothermal energy holds great potential for a sustainable future, as it is a clean and weather-independent form of energy. In addition to energy production, it can also serve the population of a region through direct use. In this paper, three municipal geothermal systems (Szarvas, Nagyszénás, Békéscsaba) in the same Hungarian region which have been recently installed or expanded are presented and analysed. Here, the direct usage of geothermal energy for heating purposes is a very important issue. The three systems show several differences and to some extent face different challenges in the various phases of the projects. Particular attention has been paid to engineering solutions to the problems that arise. The challenges, such as technical difficulties during installation, maintenance difficulties, or problems arising during operation are introduced. The strengths, weaknesses, opportunities, and threats of similar geothermal systems were summarized, based on the relevant literature. These points were evaluated by their appearance and characteristics in the examined systems. This study aims to provide insights, based on recently gained experiences, into geothermal projects, thus providing feedback and practical information for researchers and practitioners.

Authors:   School Economics and Law, Tra Vinh University, Tra Vinh, Vietnam, Nguyen Ha Hong
Published: May 2024

The purpose of this study is to examine how easily low-income workers can get loans for social housing projects under a Vietnamese government policy. This policy, outlined in Decision 388/QD-TTg by the Prime Minister on April 3, 2023, aims to build at least 1 million apartments for low-income individuals and industrial park workers from 2021 to 2030. The study focuses on four branches of the Vietnam Bank for Social Policy (VBSP) in the Mekong Delta region: Tra Vinh, Vinh Long, Ben Tre, and Soc Trang provinces. The research involved surveying 280 workers who applied for loans at these banks between May 2003 and September 2023. Half of these applicants met the loan criteria, while the other half did not. Using a Binary logistic regression model, the study identified several factors that influence the likelihood of obtaining a social housing loan from VBSP. These factors include the applicant's age, education level, number of dependents, marital status, total income, equity ratio, and the value of collateral. Among these, the total income, value of collateral, and equity ratio were found to have the most significant effect on loan accessibility. Based on the findings, the authors suggest policy recommendations to make it easier for low-income workers to access loans for social housing in the future, enhancing the effectiveness of the VBSP's lending program in the Mekong Delta.

Designing Health Recommender Systems to Promote Health Equity: A Socioecological Perspective (Preprint)
Authors: Figueroa Caroline A , Torkamaan Helma , Bhattacharjee Ananya , Hauptmann Hanna , Guan Kathleen W , Sedrakyan Gayane
Published: May 2024

UNSTRUCTURED

Health recommender systems (HRS) have the capability to improve human-centered care and prevention by personalizing content, such as health interventions or health information. HRS, an emerging and developing field, can play a unique role in the digital health field as they can offer relevant recommendations, not only based on what users themselves prefer and may be receptive to, but also using data about wider spheres of influence over human behavior, including peers, families, communities, and societies. We identify and discuss how HRS could play a unique role in decreasing health inequities. We use the socioecological model, which provides representations of how multiple, nested levels of influence (eg, community, institutional, and policy factors) interact to shape individual health. This perspective helps illustrate how HRS could address not just individual health factors but also the structural barriers—such as access to health care, social support, and access to healthy food—that shape health outcomes at various levels. Based on this analysis, we then discuss the challenges and future research priorities. We find that despite the potential for targeting more complex systemic challenges to obtaining good health, current HRS are still focused on individual health behaviors, often do not integrate the lived experiences of users in the design, and have had limited reach and effectiveness for individuals from low socioeconomic status and racial or ethnic minoritized backgrounds. In this viewpoint, we argue that a new design paradigm is necessary in which HRS focus on incorporating structural barriers to good health in addition to user preferences. HRS should be designed with an emphasis on health systems, which also includes incorporating decolonial perspectives of well-being that challenge prevailing medical models. Furthermore, potential lies in evaluating the health equity effects of HRS and leveraging collected data to influence policy. With changes in practices and with an intentional equity focus, HRS could play a crucial role in health promotion and decreasing health inequities.

Published: May 2024

Indonesia’s demographic bonus for the millennial generation is starting to increase. However, the quality of nutrition and health of Indonesian children is threatened by cases of stunting in several regions in Indonesia without specialized assistance from posyandu cadres as the frontline educators for parents. This community service research aimed to explore posyandu cadres' understanding of the value of positive parenting to prevent stunting through a Psychoeducation Program design. This activity program involved psychoeducational interventions using lectures, discussion, and role-play of positive parenting practices. The Positive Parenting Psychoeducation Activities were carried out involving 39 Posyandu Cadres in Ringu Rara Village, Lamboya Sub-District, West Sumba District, East Nusa Tenggara Province (N = 20) and Posyandu Cadres in Tirtoadi Village, Mlati Sub-District, Sleman District, Special Region of Yogyakarta Province (N = 19). A psychoeducation program evaluation using the open-ended questionnaire was administered before (pre-test) and after (post-test) lecture sessions, discussion sessions, and Positive Parenting training sessions. Subsequently, the trainers continued with Focused Group Discussion sessions for the follow-up stage of the training. Using a qualitative approach to thematic analysis techniques and cross-tabulations, the authors searched for themes that emerged from the questionnaire responses data and recorded focus group discussion transcripts. Besides, the data organization was also carried out with the help of the MAXQDA 2020 Application. The thematic analysis results generated three main themes around Positive Parenting Psychoeducation activities, namely Posyandu Cadres with their tasks and challenges, Positive Parenting to prevent stunting, and Positive Parenting Psychoeducation follow-up plans. The conclusion drawn from the results of this activity was that the family-household factor of parenting patterns can influence stunting. Posyandu cadres need positive parenting psychoeducation to be able to share information with, assist, monitor, and help parents of children with stunting indications.

Published: May 2024

This study was on teaching practice, a core educational planning attainment for students, challenges, and prospects. The purpose of the study was to find the perceptions of students about teaching practice and the challenges facing student–teachers during teaching practice exercises. The study was guided by two research questions and two hypotheses. The study employed a descriptive survey research design in which only existing variables were investigated without manipulating them. The targeted population for the study were students’ teachers, numbering a total of 188 from our five units of the Department of Science Education. The study employed simple random sampling to select participants. A total of 100 participants were randomly selected from Integrated Science Education, Mathematics Education, Physics Education, Chemistry Education, and Biology Education in the Faculty of Education, Akwa Ibom State University, Ikot Akpaden. The instrument used for the collection of data for the study was a questionnaire tagged teaching practice questionnaire (TPQ). Mean scores, standard deviation, and t-tests were used for the analysis of the collected data. A mean score above 2.50 indicates high while a mean below 2.50 indicates low. In conclusion, teaching practice is in constant practice and is the foundation of teaching. Based on this, it was recommended, among others, that a proper orientation for student teachers should be carried out using efficient means of communication like seminars, workshops, conferences, and discussion before they go for teaching practice.
Assessing Solar Tracker Effectiveness in Diverse Weather Conditions
Authors: Prakash Amol , Lal Kamlesh
Published: May 2024

Solar tracking systems aim to optimize solar photovoltaic (PV) panel efficiency by maximizing exposure to sunlight. This paper explores solar tracking, its benefits, and various system types, emphasizing the goal of ensuring panels are perpendicular to the sun's rays. Tracking enhances energy generation potential compared to fixed installations, increasing output by 25-35%. This boosts return on investment and reduces payback periods. In agriculture, solar tracking promotes energy efficiency, productivity, and sustainability. However, long-term benefits, economic feasibility, and environmental impacts require further research. This study proposes evaluating solar panel output under different weather conditions, comparing tracking and non-tracking modes. The analysis concludes that tracking mode generates more power than non-tracking mode. This finding underscores the efficacy of solar tracking technology in maximizing energy production. Overall, adopting solar tracking systems can foster a greener, more sustainable future, particularly in agricultural contexts.

Abstract: In computer vision, object detection is an essential job with many real-world applications, such as robots, autonomous cars, and surveillance. Because of its great accuracy and speed, the YOLO (You Only Look Once) method is a well-liked realtime object recognition technique that has attracted a lot of attention. This technique is perfect for time-sensitive applications since it examines the full image at once and predicts bounding boxes and class probabilities for recognized items. YOLO has undergone many iterations, with YOLO v5 being the most recent and sophisticated version. It utilizes anchor boxes and a feature pyramid network (FPN) to increase the accuracy of object recognition. Our goal in this research is to apply YOLO v5 to realtime picture and object identification applications stage. The model will be trained using an appropriate dataset, and its performance will be assessed against a range of benchmarks and advanced object detection methods. The project's output will offer a reliable and effective real-time object detection system that will facilitate prompt decision-making in the identification of item types and their corresponding placements. It has useful uses in robotics, autonomous driving, and surveillance.

Abstract: Drowsy driver detection system is a safety technology designed to identify the potential signs of fatigue or drowsiness of the driver to prevent accidents caused as a result of not being alert. It is a significant risk factor for traffic accidents which has led to thousands of accidents, injuries, and fatalities each year. In this system we have used some techniques to monitor the driver’s behavior or state. This involves tracking facial features, eye movements or blink patterns and yawning. The system identifies signs of fatigue, such as slow eyelid closure, increased blink duration and yawn which often indicate drowsiness. As technology advances, these systems are becoming more accurate, efficient and integrated with other vehicle safety features. The continued development of drowsy driver detection technology holds significant promise for reducing traffic accidents and improving overall road safety.

Abstract: Peer-to-peer (P2P) carpooling platforms have emerged as a promising solution to address transportation inefficiencies, reduce traffic congestion, and alleviate environmental impacts. However, existing P2P carpooling systems encounter challenges related to trust, security, and transparency. This work proposes a novel approach to enhance P2P carpooling through the integration of blockchain technology. Blockchain, a decentralized and immutable ledger, offers inherent advantages such as trust, transparency, and security. By leveraging blockchain, this proposed system aims to address key issues in P2P carpooling, including identity verification, payment settlement, and data integrity. Smart contracts, programmable self-executing agreements, enable automated transactions and enforce rules within the carpooling ecosystem.

Abstract: Driven road segmentation, a crucial part of advanced driver assistance systems, looks at the surroundings to keep vehicles within safe driving limits (ADASs). It begins by outlining the automatic lane detection shortfalls of conventional computer vision systems, pointing out problems such subpar segmentation, insufficient mask edge contours, sluggish processing, and restricted flexibility in intricate urban environments. Next, a multi-step procedure using deep learning networks is offered as a solution. This involves extracting vector skeletons, computing neighbouring pixels, assigning proportional weights depending on endpoints, and getting binary prediction masks. The conversation also touches on how self-driving technology will affect society, emphasizing how it could provide safe and intelligent transportation choices in the face of an increase in traffic accidents caused by careless drivers. Self-driving cars could be the first practical example of socially conscious robots interacting with humans, the story implies, even if it acknowledges possible public opposition. Furthermore, the story highlights the latest developments in autonomous driving technology, highlighting the vital requirement for strong sensing, perception, and cognitive technologies to enable completely autonomous vehicles that can adjust to changing road conditions.
