The Influence of Changing Belt Loading Conditions on the Operational Condition of the Belt Transmission

Given the fact that belt drives are used to transmit power to a fairly large extent, it is natural to devote scientific attention to their transmission with an effort to contribute to the constant technical and technological progress in the field of belt production and use. For testing and monitoring belt drives, a measuring system was designed and manufactured, which allowed the installation of various types of belt drives and, under a controlled load, to monitor selected parameters and the behavior of individual transmission elements. The presented contribution presents both the measuring system itself and experimental measurements on three V-belts of the same size manufactured by three different manufacturers. During the experimental measurements, parameters such as belt tension were changed by changing the axial distances of the pulley axes; by connecting electric motors through frequency converters, it was possible to control the change in the input speed of the transmission and, at the same time, the load on the output pulley. On the proposed specific design solution for testing belt drives, the actual speed of the input and output pulleys was measured by sensors to determine the belt slip, and the belt’s floating in one plane was monitored using high-precision distance measurement sensors. The analysis of the belt drives also included an assessment of their impact on other parts of the machine or equipment (for example, when transmitting large forces, this can have a negative impact on bearings and gearbox components) on which they are installed; therefore, vibration measurements were also performed. The results of the experimental measurements can contribute to designers choosing a belt drive, for example, even under boundary load parameters and extreme conditions.

Key Parameter Design and Experimental Analysis for Peelable Seedling Belts in Sweet Potato Transplanting Systems

Sweet potato is essential for food security, but its transplanting efficiency is currently low. To improve this, we developed a belt-type transplanter that uses seedling belt technology for automated feeding, increasing efficiency by over 25%. The use of the seedling belt is key to significantly enhancing the transplanter’s efficiency. Building on seedling belt feeding, we designed a “trumpet-shaped” staggered detachable seedling belt using LDPE film. Seedlings are fixed at intervals between two film layers via thermal bonding points. Mechanical analysis showed the optimal peeling strength is 13.2 N, ensuring smooth seedling transport during transplanting. Peeling strength depends on the heat sealing temperature, time, and pressure. To optimize these parameters, we designed an experimental device and conducted single-factor experiments to determine their effects on the peeling strength and establish reasonable ranges. Results show that, at a peeling strength of 13.2 N, the thermal bonds separate smoothly without tearing the film. A three-factor, three-level orthogonal experiment further optimized the heat sealing parameters, concluding that, at 140 °C, 1.2 s, and 0.4 MPa, the average peel force of the seedling tapes obtained from the experiments was 14.31 N, at which point the peeling effect was optimal.

Risk factors, management and outcomes for peritoneal dialysis access damage

Objectives: Peritoneal dialysis (PD) access damage is an uncommon complication of PD. This study aimed to describe the characteristics, management and outcomes of PD access damage. Methods: This retrospective study included patients who suffered from PD access damage between January 2018 and January 2024 at the PD Center of West China Hospital. Patient characteristics and access damage information were collected from medical records. Results: A total of 128 PD patients without PD access damage were included in the control group. A total of 45 patients (51% male; aged 58 ± 14 years) suffered from 49 cases of PD access damage. Multivariate logistic analysis revealed that previous peritonitis [odds ratio (OR) 3.93; 95% confidence interval (CI) 1.56 to 9.94] and assisted PD (OR 4.20; 95% CI 1.25 to 14.12) were risk factors, while catheter belt use (OR 0.16; 95% CI 0.06 to 0.44) and training frequency per year (0.34; 95% CI 0.19 to 0.64) were protective factors against PD access damage. Managements included cutting and repairing (N = 24), transfer set replacement (N = 11), catheter removal (N = 9) and catheter replacement (N = 4). Thirty-nine patients continued with PD after access repair and were followed up for a median of 35 months. The repaired access functioned well during follow-up. Conclusions: In conclusion, to avoid PD access damage, catheter belt and routine retraining are recommended. Once PD access damage is identified, patients should clamp the catheter, take prophylactic antibiotics and resort to the treatment team. The treatment team should evaluate PD access and handle it according to a clinical protocol.

Alcohol perceptions and driving decisions among adolescents: Exploring the role of peer and parental influences in Virginia

Objective This study aims to explore the role of peer and parental influences on adolescent driving behaviors, particularly concerning distracted and alcohol-impaired driving, in light of the significant number of road accidents and fatalities involving young drivers. Methods A cross-sectional study was conducted using data from the IMPACT program. Adolescents aged 14 to 19 in the Richmond area were recruited from local high schools through convenience sampling. Parental consent was obtained via media release forms provided by Virginia Commonwealth University (VCU), with students having the option to opt out of participation. Self-report surveys were administered during IMPACT program events and captured via REDCap. The surveys included demographic information, driving history, driving behaviors, alcohol attitudes, drinking and driving behaviors, and a driving knowledge section. Results The mean age of participants was 15.230 years (SD = 1.545). Gender distribution was as follows: Female 53.1% and male 42.1%. Racial distribution included White/Caucasian (48.9%), Black/African American (22.4%), and multiple races (8.8%). Peer influence on drinking and driving was significant (P = .038). Driving under the influence was associated with both parental and peer influence (P < .050). A positive correlation was found between peer digital distraction and car crashes (coefficient = 0.038, P = .038). Additionally, parental alcohol-impaired driving was linked to decreased positive attitudes among adolescents toward driving under the influence (coefficient = −0.024, P = .000). Though parent distracted driving positively influenced adolescent driving behavior, this effect was not statistically significant (coefficient = 0.008, P = .320). Conclusion The findings indicate a significant reduction in risky behaviors such as drinking and driving and an increase in seat belt use among adolescents. There is heightened awareness regarding the dangers of texting and driving. A multifaceted approach was effective in improving attitudes and practices related to driving safety.

Predicting risky driving behaviours using the theory of planned behaviour: A meta-analysis

The current meta-analysis explored the efficacy of the theory of planned behaviour (TPB) in predicting high-risk driving behaviours. Specifically, we examined speeding (in relation to exceeding the limit as well as speed compliance), driving under the influence, distracted driving, and seat belt use. We searched four electronic databases (i.e., PubMed, Web of Science, Scopus, and ProQuest) and included original studies that quantitatively measured the relationships between the TPB variables (attitude, subjective norm, perceived behavioural control [PBC], intention, and prospective/objective behaviour). The study identified 80 records with 94 independent samples. Studies were assessed for risk of bias using the JBI checklist for cross-sectional studies and compliance with the TPB guidelines. Together, attitude, subjective norm and PBC explained between 30 % and 51 % of variance found in intention, with attitude showing as the strongest predictor for intention across the different driving behaviours. The findings also showed that the model explained 36 %–48 % variance found in predicting the observed and/or prospective behaviours for distracted driving, speed compliance and speeding. Understanding the varying strengths and thus relative importance of TPB constructs in predicting different risky driving behaviours is crucial for developing targeted road safety interventions.

Conclusion: Corrective actions that can be taken to minimize the occurrence of mining accidents in truck transportation activities are: increasing supervision and socialization related to speed limits, as well as the use of safety belts and helmets; striving for engineering, maximizing supervision and completing road signs on downhill road segments with grades above 12% and long; implementing new worker training and annual refresher courses with output in the form of SIMPER which is valid for a maximum of 1 year; meeting the needs/ratio of operational supervisors, and ensuring that SOP and IBPR are adequate for truck transportation activities.

An overview of the constructions of conveyors for moving bulk materials, comparison and study of their parameters

The production of concrete mixes, along with their use in the production of building materials and structures, is one of the key processes in the construction industry during the construction, restoration and repair of buildings and structures. Because of this, the need to create modern concrete mixing plants that will meet the requirements of minimum energy consumption and maximum productivity of concrete mixture production is an urgent task. Not only the main operations, which include the dosing of the components of the mixture and their mixing, but also the maintenance operations, namely operations that ensure the timely movement of the components of the concrete mixture from warehouses to the main technological equipment, affect the set rhythm of the concrete mixture production. Conveyors of various types and designs are used to move bulk materials, such as crushed stone and sand. For the rational selection of such equipment in accordance with the characteristics of the cargo to be transported, knowledge of the types of conveyors, their structures and parameters, understanding of operation issues and methods of parameter calculation are required. In addition, it is worth paying attention to the following parameters: maximum cargo transportation productivity, low energy consumption per unit of moved products, low metal content of the structure. The work reviewed the most common designs of conveyors used to move bulk materials in concrete mixing plants, analyzed the disadvantages and advantages of conveyors, as well as technical parameters. As a result, the predominant directions for the use of belt and plate conveyors at construction enterprises were determined. The advantages of belt conveyors, which contribute to their widespread distribution, are high productivity, simplicity of design, reliability, quiet operation, low specific power consumption. When choosing a conveyor, it is recommended to choose the equipment with the highest productivity and the lowest power of the drive motors, however, the performance should be clearly related to other technological equipment.

Head and Neck Airbag Penetrating Injuries.

Airbags have significantly decreased fatalities in frontal vehicle accidents, but their deployment can lead to more severe injuries and rarely death. The authors present a case of a penetrating injury causing tissue loss in the left cheek, an "explosion" of the zygomatic arch, and facial nerve damage, discussing the management in the contest of literature examining similar injuries in the head and neck region. Reviewing English literature from 1995 to 2023, 9 patients experienced severe airbag-related penetrating head and neck injuries, in 3 cases resulting in death. In addition, we describe the case of a young male reporting a deep cheek laceration with facial nerve damage, tissue loss, and comminuted maxilla-zygomatic fracture; 48 hours after trauma, he underwent surgical reconstruction using a bilobed flap, direct suture of the resected masseter muscle, closed reduction of the comminuted zygomatic arch fracture, and direct neurorrhaphy of the lacerated facial nerve. Five months after surgery, facial nerve function recovery was observed. Mouth opening was restored, but a mixed low-medium hearing loss persisted for high frequencies. In another case marginal nerve damage was reported, but management is not described. The use of seat belts and airbags has led to a significant reduction in the incidence of facial fractures and fatalities after motor vehicle accidents, but at the same time, in some cases, complex facial trauma and/or penetrating injury can be observed. In case of suspected or certain facial nerve damage, it is mandatory to perform exploration and eventual reconstruction within 72 hours.

Green Belt Legislation Regulation: Comparative Legal Research

Recently, legislative acts on the protection of the green belt have been increasingly adopted in various states. Using the legislation examples of the United Kingdom, the Canadian province of Ontario, and Russia, we have identified public relations that can be the subject of regulation of such legislation. Based on the analysis of typical legal conflicts, the problem areas which need the most attention of the legislator have been identified. The methods of differentiation of the legal regime for various areas within the green belt are investigated, taking into account their geographical features and specific management goals. The most promising areas for legal regulation that require the increased attention of legislators speak to the establishment of the procedures and criteria for excluding land plots from the green belt, the regulation of village development processes within the green belt, the establishment of a comprehensive list of agricultural types of permitted use, and the establishment of the procedure for the development of specialized plans or strategies for the use and protection of the green belt. The article offers solutions to these issues. The methodology of comparative law, including the functional method, was used in the study.

Evaluation of the effectiveness of road safety measures and their impact on the pattern and distribution of extracranial and intracranial hemorrhages in fatal head injury cases in Uttar Pradesh, India

Introduction: In Uttar Pradesh, India, there are many fatal head injuries as a result of road traffic accidents (RTAs). Studying the pattern and distribution of intracranial hemorrhages, a frequent complication of severe head trauma might provide vital information on the efficacy of traffic safety regulations. To improve road safety tactics and lower fatal head injuries in Uttar Pradesh, this study intends to assess the effect of road safety measures on the frequency and distribution of intracranial hemorrhages in fatal head injury patients. Aim: This study’s objective is to assess the influence of current road safety initiatives on intracranial bleeding distribution and patterns in fatal head injury cases in Uttar Pradesh. Methodology: The 604 RTA cases with head injuries that were brought to the mortuary of the S.R.N. Hospital in Prayagraj for a medical-legal postmortem assessment over the course of a year, from April 2021 to March 2022, make up the entirety of this prospective study. Following receiving institutional ethical approval and informed consent, structured interviews with attendees utilizing a questionnaire were done to gather the data. Result: The results show that certain traffic safety measures have reduced the frequency of fatal head injuries in RTAs. A decreased incidence of intracranial hemorrhages was linked to improved traffic infrastructure, including well-planned junctions, pedestrian crossings, and distinct bicycle lanes. Similar results were shown in serious head injuries when traffic restrictions including speed limits, seat belt use, and helmet legislation were strictly enforced. Conclusion: There are still issues with fatal brain injuries from car accidents, despite some encouraging results. Safety legislation violations, a lack of public knowledge, and inadequate enforcement all contribute to the issue. Disadvantaged groups like walkers and users on two-wheelers continue to be especially susceptible. The results of this investigation offer important new understandings of the efficiency of traffic safety measures and their influence on the distribution and pattern of cerebral hemorrhages in Uttar Pradesh, India. The results point to the necessity of improved public education efforts and traffic safety laws. More research and focused interventions are required to address specific risk factors among various road user groups. This will result in a safer driving environment and a decline in catastrophic brain injuries.

Seat Belt Use and Perceptions Among Inter-Urban Commercial Vehicle Drivers in Ilorin, Nigeria

Implementation of stroke care & road safety in India: Lessons from Australia.

India is home to one-fifth of the world's population and is currently the fastest-growing economy. As the health industry is growing, India needs to develop robust implementation of evidence-based health care addressing the major public health issues. Two of such issues India is grappling with are the establishment of stroke care and the reduction of road accidents. Australia has achieved notable success in implementing stroke care and reducing road accidents. In stroke, Australian initiatives include dedicated stroke units, the development of clinical guidelines, the implementation of acute interventions, the establishment of a national stroke foundation, and the stroke registry. As a result, the combined, primary, and secondary prevention measures, acute treatment, and rehabilitation have reduced the total disease burden of stroke from 2003 to 2023 by 53 per cent, from 7.4 to 3.5 Disability Adjusted Life Years (DALYS) per 1,000 population, which is a 56 per cent decline in fatal burden and 23 per cent decline in non-fatal burden. For road safety, Australia implemented evidence-based practices such as education, legislation including mandatory use of seat belts, and other road safety initiatives. Data show that seat belt use reached 98 per cent in Australia in 2023. Furthermore, about 20 per cent of drivers as well as passengers who were killed in crashes in 2024 did not wear seat belts. The reduction of speed limits in built-up areas, the adoption of monitoring technology, and the clever use of infrastructure are proving to be effective in reducing fatalities and serious injuries. Australia's implementation research can provide valuable insights into the efforts of mitigating the impact of stroke and enhancing road safety in India.

Cervical vertebral and spinal cord injuries in rollover occupants

BackgroundRollover crashes continue to be a substantial public health issue in North America. Previous research has shown that the cervical spine is the most injured spine segment in rollovers, but much of the past research has focused on risk factors rather than the actual cervical spine injuries. We sought to examine how different types of cervical spine injuries (vertebral and/or cord injury) vary with different occupant-related factors in rollovers and to compare these with non-rollovers.MethodsWe obtained crash and injury information from the National Automotive Sampling System–Crashworthiness Data System (NASS-CDS) for 2005–2015 and Crash Investigation Sampling System (CISS) for 2017–2022. Based on weighted data, we calculated relative risks to assess how occupant sex, seat belt use, ejection status, and fatal outcome relate to the rate of different cervical spine injuries in rollovers and non-rollovers.ResultsIn NASS-CDS occupants with cervical spine injuries (N = 111,040 weighted cases), about 91.5% experienced at least one vertebral injury whereas only 11.3% experienced a spinal cord injury (most of which had a concomitant vertebral fracture). All types of cervical spine injuries we examined were 3.4–5.2 times more likely to occur in rollovers compared to non-rollovers. These relative risks were similar for both sexes, belted and unbelted, non-ejected, and non-fatal occupants. The number of weighted CISS occupants with cervical spine injuries (N = 42,003) was smaller than in the NASS analysis, but cervical spine injuries remained 6.25 to 6.36 times more likely in rollovers compared to non-rollovers despite a more modern vehicle fleet.ConclusionsThese findings underscore the continued need for rollover-specific safety countermeasures, especially those focused on cervical spine injury prevention, and elucidate the frequency, severity and other characteristics of the specific vertebral and spinal cord injuries being sustained in rollovers. Our findings suggest that countermeasures focused on preventing cervical vertebral fractures will also effectively prevent most cervical spinal cord injuries.

Safety climate and seat belt use in the fire service

Objective Motor vehicle incidents or apparatus crashes are a leading cause of firefighter fatalities in the United States. Nonuse of seat belts has been linked to some of these fatalities. This research seeks to understand the relationship between safety climate and seat belt use among firefighters, as findings will provide insights into factors that may bolster seat belt use and protect firefighters. Methods Data were collected from 208 career firefighters working for a city fire department in the southeastern United States. Structural equation modeling was used to test a hypothesized model and to assess the relationships between organizational safety climate, work group safety climate and seat belt use. Results It was determined that positive perceptions of workgroup safety climate, as a higher order factor, comprised of supervisor support, horizontal cohesion, and vertical cohesion, was positively associated with seat belt use within a sample of firefighters. Organizational level safety climate did not have a significant relationship with seat belt use but did positively influence workgroup safety climate perceptions. Conclusions Safety climate has been associated with safety compliance and participation behaviors, but more research was needed to specifically examine the impact of safety climate on seat belt use in firefighters. The findings point to the importance of safety climate as a leading indicator and predictor of seat belt use. Bolstering safety climate through safety programs, commitment to safety, effective communication, supportive supervisors and cohesion should ultimately aid in bolstering seat belt use among firefighters, which is important to curtailing firefighter injuries and fatalities.

Convolutional Neural Network and LSTM for Seat Belt Detection in Vehicles using YOLO3

The application of an electronic violation detection system has begun to be implemented in many countries using CCTV cameras installed at highway and toll road points. However, the development of a violation detection system using data in the form of images that have a high level of accuracy is still a challenge for researchers. Several types of violations detected include the use of seat belts, the use of cell phones while driving, which is influenced by the number of vehicles, vehicle speed and lighting, which can increase the difficulty in the detection process. This research developed a traffic violation detection system using a hybrid model, namely the CNN and LSTM algorithms for the application of discipline using seat belts. The dataset was obtained from RoboFlow Universe with a total of 199 front view car images consists of 82 using seatbelts and 78 not using seatbelts for the training process. The CNN algorithm plays a role in the feature extraction process from input image data, while the LSTM algorithm plays a role in the prediction process. Additionally, the performance evaluation of the CNN+LSTM algorithm will be measured using the accuracy value to measure the performance of the training process and testing process. When measuring the performance of the training process, it will be compared with several basic detection models used, such as CNN, VGG16, ResNet50, MobileNetV2, Yolo3, Yolo3+LSTM. The test results show that Yolo3+LSTM has a higher accuracy compared to the others, at 89%. Next, in the testing process, the CNN+LSTM model will be compared with the basic method, namely CNN. The test results show that the CNN+LSTM models have a higher accuracy of 89%. Meanwhile, in the basic CNN model, the resulting accuracy was 85%.

Evaluation of Adolescents' Awareness of Seat Belt Use and the Relationship with Risky Behaviors.

The one of the leading causes of adolescent morbidity and mortality worldwide is motor vehicle accidents (MVA). The use of seat belts significantly lowers MVA fatalities and injuries. The aim of this study is to investigate adolescent seat belt usage patterns and relation with risky behaviors. The study conducted at two medical institutions with non-immigrant and literate adolescents aged 12-18. Demographics, seat belt use, and risk-taking behavior were collected through questionnaires. 726 teenagers (422 girls and 304 boys) with an average age of 176.7 ± 23.37 months participated in the study. Parents' educational levels and front-seat belt use have been found to be correlated. Comparatively to non-users, seat belt users demonstrated lower risk scores (total, traffic, substance, and social). The use of seat belts was significantly predicted by traffic risk, according to logistic regression. The frequency of seatbelt use was higher among participants from cities with higher socioeconomic status. As a result, it was found that adolescents who exhibited more risky behaviors had a lower frequency of seat belt use and seat belt use was associated with socioeconomic level and parental education level. It is thought that population-based studies to be conducted on this subject are important.

Risk stratification and predictive modeling of postoperative delirium in chronic subdural hematoma.

Background- Postoperative delirium is a common complication associated with the elderly, causing increased morbidity and prolonged hospital stay. However, its risk factors in chronic subdural hematoma patients have not been well studied. Methods- A total of 202 consecutive patients with chronic subdural hematoma at Peking University Third Hospital between January 2018 and January 2023 were enrolled. Various clinical indicators were analyzed to identify independent risk factors for postoperative delirium using univariate and multivariate regression analyses. Delirium risk prediction models were developed as a nomogram and a Markov chain. Results- Out of the 202 patients (age, 71 (IQR, 18); female-to-male ratio, 1:2.7) studied, 63 (31.2%) experienced postoperative delirium. Univariate analysis identified age (p < 0.001), gender (p = 0.014), restraint belt use (p < 0.001), electrolyte imbalance (p < 0.001), visual analog scale score (p < 0.001), hematoma thickness (p < 0.001), midline shift (p < 0.001), hematoma side (p = 0.013), hematoma location (p = 0.018), and urinal catheterization (p = 0.028) as significant factors. Multivariate regression analysis confirmed the significance of restraint belt use (B = 7.657, p < 0.001), electrolyte imbalance (B = -3.993, p = 0.001), visual analog scale score (B = 2.331, p = 0.016), and midline shift (B = 0.335, p = 0.007). Hematoma thickness and age had no significant impact. Conclusion- Increased midline shift and visual analog scale scores, alongside restraint belt use and electrolyte imbalance elevate delirium risk in chronic subdural hematoma surgery. Our prediction models may offer reference value in this context.

Prediction of rear-seat belt use: Application of extended theory of planned behavior

Objectives Rear-seat belts have been shown to significantly reduce the severity of road vehicle collisions and fatalities. However, their use by rear-seat passengers is significantly less than that by front-seat passengers. Thus, the psychological factors underlying individuals’ decision to wear a seat belt in the rear seat require further investigation. Methods An extended theory of planned behavior (eTPB) was used to examine individuals’ behavior of wearing a rear-seat belt. An online survey was conducted and a total of 515 valid questionnaires were collected in China. Results While attitude, descriptive norms, and law enforcement all have a significant effect on individuals’ intention to wear a seat belt in the rear, subjective norms and perceived behavioral control do not. Individuals’ attitudes toward wearing a seat belt in the rear seat are significantly influenced by law enforcement and behavioral intention, but not by perceived behavioral control. The mediation effect analysis reveals that law enforcement has the greatest overall effect on behavior, followed by attitude and descriptive norms. Conclusions The results of this paper contribute to more effective recommendations to improve the use of rear seat belts and to safeguard rear seat passengers.

IJCM_246A: Estimating the prevalence of seat belt usage in motor cars: A descriptive cross-sectional study in Mangalore

Background: Every year 1.25 million people die of road traffic accidents. Several safety measures can be taken to prevent RTAs. The SDG 2030 set the target to halve the number of global death and injuries from road traffic accidents by the year 2020. The aim of this study is to estimate the prevalence of seat belt use and factors influencing it including driver characteristics, type of car and time of day and distractions while driving. Methodology: This Descriptive cross-sectional study was set on the major roads and intersections of Mangalore, recruiting the drivers and front-seat passengers in the motor cars at the time and site of observation. Results: A total of 6165 motor cars were observed. 15 (0.2%) of these cars had completely tinted car windows, therefore out of the total, 6150 motor cars could be properly observed. 70.91% (4361) of drivers were wearing seat belts. Seat belt usage among drivers was found to be higher on highways (76.6%) as compared to on residential and city roads (69.3%). In vicinity of traffic police, 76.5% of drivers were observed to be wearing seat belts in contrary only 67.8% of them were wearing seatbelts in the absence of traffic police. Prevalence of mobile phone use and other distractions amongst drivers was 2.1%. Out of 2646 adult front seat passengers observed, only 10.9% were wearing seat belts. Conclusion: Among drivers, type of motor car, traffic zone and type of road and presence of traffic police in vicinity are significantly associated factors with seatbelt usage. Among adult front seat passengers, type of motor car, traffic zone, type of road and presence of traffic police in vicinity are significantly associated. Among front seat child passengers, type of road and traffic zone are significantly associated with seat belt usage.
