Effects of shoes on kinetics and kinematics of the squash forward lunge in male players
This work is licensed under a Creative Commons Attribution-NonCommercial 4.0 International License.Squash is associated with a high incidence of chronic injuries. Currently there is a trend in many sports for players to select minimalist footwear. The aim of the current investigation was to examine the effects of squashspecific, running shoes and minimalist footwear on the kinetics and 3-D kinematics of the lunge movement in squash players. Twelve male squash players performed lunge movements whilst wearing minimalist, running shoe and squash-specific footwear. 3-D kinematics of the lower extremities were measured using an eightcamera motion analysis system alongside kinetic and tibial acceleration information which were obtained using a force platform and an accelerometer. Differences between footwear were examined using one-way repeated measures ANOVA. The results show firstly that loading rate parameters were significantly greater in the minimalist (average = 85.36B.W/s and instantaneous = 179.09B.W/s) footwear in relation to the squashspecific (average = 38.66 B.W/s and instantaneous = 50.73B.W/s) and running footwear (average = 37.62B.W/s and instantaneous = 48.14B.W/s). In addition, tibial acceleration parameters were also significantly greater in the minimalist (peak tibial acceleration = 8.45 g and tibial acceleration slope = 422.28g/s) footwear in relation to the squash-specific (peak tibial acceleration = 4.33 g and tibial acceleration slope = 182.57g/s) and running footwear (peak tibial acceleration = 4.81 g and tibial acceleration slope = 226.72g/s). The significant increase in impact loading in the minimalist footwear therefore suggests this type of shoe may place squash players at an increased risk of developing impact-related chronic injuries.Peer reviewedFinal Published versio
Artificial Intelligence and Neurosurgery: A Revolution in The Field
Artificial Intelligence (AI) is being used in the field of neurosurgery for improving patient outcomes, reducing the risk of complications, and increasing the efficiency of surgical procedures. AI algorithms can analyze patient data, plan surgical procedures, guide surgical instruments, monitor brain activity, and improve post-operative care. The benefits of incorporating AI into neurosurgical practice include pre-operative planning, intraoperative navigation, real-time monitoring, and post-operative care. AI is already being used in neurosurgery for image segmentation, surgical planning, intraoperative navigation, real-time monitoring, and predictive analytics. The potential applications of AI in neurosurgery include personalized medicine, virtual reality, robotic surgery, predictive analytics, and medical imaging. However, the challenges of incorporating AI into neurosurgical practice are data quality, data privacy and security, regulatory frameworks, and training and education. In short, AI has the potential to completely transform the discipline of neurosurgery, but there is a need to address the challenges associated with its incorporation into neurosurgical practice

Designing a New Cement Composition Using Agricultural Wastes for Underground Gas Storage
To reinforce cement against the attack of supercritical CO2 in a storage site, agricultural wastes (POFA and RHA) and Nano particles (Nano Silica) were used. Post-carbonation tests of agricultural wastes and Nano Silica based cement were done according to the API standard and it was found that almost all samples have a lesser carbonated area then the neat cement except 5 wt% POFA. Nano Silica based cement seem to be the best choice
The relationship of personality traits, gender, occupational stress and job satisfaction among police officers in Punjab, Pakistan
The aim of this research was to investigate the relationship between personality traits
(neuroticism, extraversion, openness to experience, agreeableness, conscientiousness),
occupational stress and job satisfaction among police officers in Punjab, Pakistan. Another aim was to examine the differences in police officers' personality traits, occupational stress and job satisfaction according to their gender. This study also examined which personality trait has more effect on job satisfaction. The respondents were 300 senior police officers from Punjab, Pakistan. The multistage sampling method consisting the stratified sampling technique and the simple random sampling technique was used. The research instruments consisted of the Neo Five Factor Inventory (NEOFFI), the Police Stress Questionnaire (PSQ) and the Job Satisfaction Survey (JSS). The Statistical Package for Social Sciences was utilized to perform descriptive and inferential statistical analysis. The results of this research indicated that a significant correlation exists among the variables in this research. This study found a positive correlation between extraversion, agreeableness and conscientiousness personality traits and job
satisfaction, while neuroticism has a negative correlation, but there is no correlation
between openness to experience and job satisfaction. There is a negative correlation
between occupational stress and job satisfaction. This study also revealed significant differences in male and female police officers' personality traits. The other findings related to gender are that female police officers have higher occupational stress than male police officers, while job satisfaction level is higher among male police officers compared to females. The results of the study showed that agreeableness has a more
significant effect on job satisfaction compared to other personality trai
Influence of minimalist footwear on knee and ankle loads during the squash lunge
Squash is associated with a high incidence of knee and ankle joint injuries. The aim of this work was to examine the effects of squash specific, running shoes and minimalist footwear on knee and ankle loads during the lunge movement in squash players. Twelve male squash players performed lunge movements whilst wearing squash specific, running shoes and minimalist footwear. The loads experienced by the knee and ankle joints were calculated. Patellofemoral forces were significantly greater in running shoes (5.10 B.W) compared to minimalist footwear (4.29 B.W). Achille tendon forces were significantly larger in the minimalist footwear (3.10 B.W) compared to the running shoes (2.64 B.W) and squash specific footwear (2.88 B.W). This shows that whilst minimalist footwear may reduce the incidence of knee pathologies in squash players corresponding increases in ankle loading may induce an injury risk at this joint
