Doubly Fed Induction Generator: Grid Integration and Performance Analysis

Renewable energy sources are emerging to replace conventional energy sources in the energy mix as a result of the growing demand for power and the constraints of existing energy sources. With technological advancements, wind energy has become a promising secondary energy source, resulting in the proliferation of wind farms around the globe to bolster traditional energy systems. This has led to a rapid increase in the incorporation of wind power into the power grid, emphasizing the need to understand its effects on the system's parameters. A range of generators, including DFIG, SG, and SCIG, are used to generate wind power. Due to benefits of separate control over true and wattless power, variable speed operation and maximum power tracking, a DFIG based wind turbine became a favourite choice for power utilities

SNP′s and its correlation with hypertension: A comprehensive review

Hypertension is a growing global problem, which mostly affects the adults. It is a risk factor for death from stroke, myocardial infarction, congestive heart failure, ischemic heart disease, peripheral vascular disease, and progressive renal damage. These diseases are responsible for considerable morbidity and high mortality rate. Human essential hypertension (EH) is a complex and multifactorial trait influenced by environmental and genetic determinants. Early detection of genetic predisposition in hypertensive patients will enable prompt treatment and avoidance of complications. The use of SNPs in genetic disease detection is facilitated by the recent discovery of more than 4 million SNPs in the human genome that have the potential to be a rich source of genetic markers to establish genetic linkage and as indicators of disease. Such genetic research will open the new frontiers in diagnosis and treatment of diseases like hypertension

Single nucleotide polymorphisms and periodontitis

The susceptibility to various diseases is studied with association to genetic polymorphisms. Among these polymorphisms, single-nucleotide polymorphisms (SNPs) are very common throughout the genome. The recent advances in genetic assay techniques and increase in SNP databases are paving a way for investigation of susceptibility genes for periodontitis. This article attempts to review the role of SNP and its implications in periodontal disease and management

Hepatitis B: Knowledge and attitude of graduating dentists from faculty of dentistry, Sebha University, Libya

Background: Hepatitis B virus (HBV) is a major worldwide cause of acute and chronic liver infection. Dentists, dental students, and their paramedical staff are at a heightened risk of exposure to HBV. Aim: The aim of this study was to assess the knowledge and attitude of the graduating dentist from Faculty of Dentistry, Sebha University (Libya), toward hepatitis B infection. Subjects and Methods: Ninety-nine participants completed the self-administered, structured, pilot-tested close-ended 37-item questionnaire. Results: It was found that the graduating dental students from different study years have similar knowledge and attitude, except for the responses to questions on curriculum, contracting hepatitis B virus (HBV) from patient, vaccination schedule, perception, and treatment modality for HBV-infected patient, where statistically significant difference was noted. Conclusion: The results indicate that there is need to spread greater awareness about risk and seriousness of the HBV infection among the graduating dentists. We recommend that the dental policymaker considers modifying the dental curriculum to include a detailed session of training in areas of universal infection control procedures, handling high-risk patients, combating fear while treating patients, and teaching them to avoid discriminatory behavior beginning in the 3rd year itself

Hepatitis C: Knowledge and attitude of graduating dentist from Faculty of Dentistry, Sebha, Libya

Objectives: The present study was undertaken to assess the knowledge and attitude of the graduating dentist with respect to various aspect of hepatitis C. Materials and Methods: A cross-sectional survey using a self-administered, structured, and pilot tested closed-ended 26-item questionnaire was completed by 99 dental students from Faculty of Dentistry, Sebha (Libya). Descriptive analysis was carried out, and Chi-square test was used for intergroup comparison. Results: Overall 54.5% students reported that their knowledge with respect to hepatitis C virus (HCV) infection was inadequate. 45.5% participants felt that books were the most common source for acquiring HCV information. Only, 44.4% participants were willing to treat high-risk HCV, patients. 70.7% interns feel that the dentists should not have the right to reject treating an HCV patient. 83% of the participants said that a dentist can contract hepatitis C from their patients if they do not use proper barrier techniques intergroup comparison showed statistically significant difference with issues related to contracting HCV from patient, HCV vaccine, treating patient in normal setting, perceptions toward HCV patients, and attitudes toward providing treatment. Conclusion: The study revealed that the knowledge of HCV among the dental students was not satisfactory, and their attitude toward HCV patients was discriminatory
