Electricity Generation of Solar Photovoltaic System

The SPV electricity generation employs various cell technologies namely polycrystalline, mono crystalline, amorphous, CIGS cells. To evaluate the performance of SPV plant a mathematical model was generated base on empirical relations and performance was calculated under various conditions. The electrical output was calculated based on various parameters such as tilt angle, cell technology, radiation levels. Sensitivity analysis was also carried out at five different geographical locations namely New Delhi, Ladhak, Jodhpur Mumbai, and Bangalore. The result shows that electrical output is maximum for polycrystalline cell at a give location and at tilt angle of plus minus 50 of location. Jodhpur was found to be the best geographical local followed by New Delhi

Comparison of the Operative Time and Post-Operative Pain with Peek Cage versus Autologous Iliac Crest Bone Graft in Anterior Cervical Discectomy and Fusion

Objective:  To compare the operative time and post-operative pain with PEEK cage method versus autologous iliac crest bone graft in anterior cervical discectomy and fusion in the cervical spine. Material & Methods:  This randomized control trial study (RCT). 90 patients with cervical disc disease, cervical stenosis with or without myelopathy and cervical trauma (fractures or facet jumps with disrupted disc) were included in the study from the Department of Neurosurgery, LGH, PINS, Lahore. Patients were evaluated with plain X-rays and MRI scans of the cervical spine. All patients underwent anterior cervical decompression and fusion. In 45 patients (group A), cervical fusion was achieved with PEEK cage method and in other 45 patients (group B), autologous Iliac Crest Bone graft was used. Results:  Mean age in group A was 57.1 years and in group B, it was 54.7 years. In group A, 31.1% patients were of cervical disc disease, 28.8% of cervical degenerative stenosis and 40% were of cervical trauma. In group B, 15 patients 33.3% were of cervical disc disease, 24.4% of cervical degenerative stenosis and 42.2% were of cervical trauma. The mean Postoperative Visual Analogue Scale (VAS) score for pain was 2.8 in group A and 5.4 in group B patients. Conclusion:  The patients of group A (PEEK cage method) could be easily mobilized within bed and out of bed depending upon their neurological status. Decreased operative time and less post-operative pain makes PEEK cage method superior to autologous iliac crest bone graft in anterior cervical decompression and fusion

Factors Affecting the Corporate Governance Disclosure: An Analysis of Manufacturing Companies in Pakistan

In this manuscript, researcher examines the effect of different governance related variables on corporate governance disclosure in Pakistani manufacturing firms. The population for this particular study was Pakistan. Secondary sample was taken from Karachi Stock Exchange (KSE) indexed companies in Pakistan. There are total 903 companies listed in KSE in 2016 according to Pakistan Stock Exchange (Pakistan Stock Exchange, 2016). According to PSE; 903 companies were listed with KSE; out of 903, 129 were selected as part of sample for this particular study. The analyses are done through Logistic regression with the use of Stata software. A disclosure index consisting the four items which are adopt to serve as dependent variable. Independent variables are; Board Composition, Managerial Ownership and Audit firm status and there are two control variables Organization size and Organization age. Result of the study suggests that the Corporate Governance disclosure that is our dependent variable have positively affected by board composition and audit firm status. Managerial ownership have negative affect on corporate governance disclosure. In previous studies, managerial ownership also showed negative impact on corporate governance disclosure and here in this study impact was also same. The hypothesis related to managerial ownership is rejected in this study. Remaining hypothesis related to audit firm status and board composition are accepted. The findings reveals that all the independent variables except managerial ownership have not found positive relationship with the determinants of Corporate Governance disclosure

Nutrition nurturers: Empowering primary school children through innovative dietary education and parental engagement

Purpose: This research aims to examine effective pedagogical methods for promoting healthy dietary practices among elementary students. By reviewing the literature, the study will identify key factors influencing children's eating habits, assess treatment impacts on eating patterns and metabolism in obese children, and explore how breakfast quality affects the health of children and teenagers. Method: This study analyses pertinent literature on encouraging healthy eating habits in primary school students using a systematic review and meta-analysis methodology. Comprehensive searches of electronic databases, such as PubMed, PsycINFO, and Web of Science, are part of the systematic review process to find pertinent research published in peer-reviewed journals. The inclusion criteria cover research on instructional methods, tactics, and interventions intended to encourage primary school students to eat healthily. Result: The outcomes of the meta-analysis and systematic review point to several successful instructional methods and tactics for encouraging primary school students to eat healthily. Children's eating habits are influenced by several factors, and treatments that focus on diet and metabolic responses, especially in obese kids, seem to be working well. The study also emphasizes how important a healthy breakfast is to kids' and teens' overall health and well-being. Conclusions: The study concludes that raising lifelong good eating habits in primary school students requires comprehensive strategies incorporating nutritional education, parental involvement, and community support. The results have significant ramifications for educators, legislators, and medical professionals who work to encourage children to adopt healthy habits. To investigate the long-term impacts of interventions and create specialized tactics for a range of populations, more study is necessary

Evaluating Learnability and Accessibility of a Software for Engineers: Case of Model Server Manager (MSM) at Jotne

Master i universell utforming av IKTLearnability and accessibility are fundamental aspects of every system. They are important qualities that make a system easily and quickly usable and understandable by new users as well as users with disabilities. There is a swift growth in the need of ICT-solutions that are learnable and accessible to everyone partly due to Convention on the Rights of Persons with Disabilities (CRPD) and country-specific anti-discrimination laws that require design of accessible ICT systems for all, including persons with disabilities. Beside compliance to the laws, designing products which are easily understandable and usable by larger group of users, including people with disabilities, would establish the competitive advantage of an organization. There have been usability and accessibility guidelines that could be used to ensure accessibility and usability of software and web-based systems. There have also been guidelines specific to learnability proposed by some researchers. This study aims to evaluate learnability and accessibility of a software Model Server Manager (MSM) which is developed by Jotne IT, a company in Norway, and recommend solutions that could improve its learnability and accessibility in future updates of the software. The study used a combination of heuristic evaluation performed by the author and a developer of MSM followed by online interviews with the users of MSM. The data collected was analyzed through thematic analysis. This research found some problems which could be related to the low-level adoption of accessibility guidelines and the requirements for universal design. Some of the problems are easy to fix while the others require some changes in organizational routines. The solutions recommended include development of organizational guidelines, development of heuristics which can be used by developers to ensure accessibility and learnability of future products, and competence development of programmers on accessibility and universal design, these measures could be helpful not only to MSM but also to other drafting tools which are used by engineers.publishedVersio
