TL;DR: In this article, a numerical evaluation of bird impact response on shrouded and un-shrouded rotating set of fan blades using three dimensional computational methodology was performed, and it was shown that the shrouded fan blades provide better impact resistance characteristics to bird impact compared to un-Shrouded fan blades.
Abstract: Aero-engine fan blades are the critical components that are vulnerable to Foreign Object Damage (FOD) such as bird impact. The thrust loss due to bird impact can affect engine core function, resulting in catastrophic failure. The fan blades should be designed to have adequate resistance to bird impact. The present paper focuses on numerical evaluation of bird impact response on shrouded and un-shrouded rotating set of fan blades using three dimensional computational methodology. The impact response is compared between shrouded and un-shrouded blades in terms of deformation, von-Mises stress, plastic strain, and energy absorbed. Numerical analysis results indicate that the shrouded fan blade absorbs 35 % more energy compared to un-shrouded blade. Deformation damage at impact location of shrouded blade is lesser compared to un-shrouded blade. The maximum plastic strain observed on shrouded blade due to bird impact is also 50 % lesser than the un-shrouded blade. The study suggests that the shrouded fan blades provide better impact resistance characteristics to bird impact compared to un-shrouded fan blades.© 2013 ASME

TL;DR: The majority of AHE students have changed their physical mobility behaviors, according to the survey, and it was discovered that a higher percentage of pupils were physically inactive, putting them at risk of acquiring an illness at a young age.
Abstract: Background: Allied and Healthcare Education (AHE) is a program that educates students for careers as physical therapists, occupational therapists, nutritionists, dietitians, medical laboratory technicians, and other health and related professionals. The healthy lifestyles of AHE students may contribute to the development of a healthy community, which is more likely to deliver good patient care. Several studies have been conducted to determine the global prevalence of physical activity (PA) and sedentary behavior among the general public. The purpose of this study is to determine the level of diurnal physical mobility and sedentary behavior among Pondicherry AHE students. Methods: The International Physical Activity Questionnaire (IPAQ) was used to collect data from 158 AHE undergraduate students, and the results were given in metabolic equivalents (MET). Results: It was discovered that 86 (54.4 percent) college students practiced low levels of physical mobility with a mean MET of 318.5, 44 (27.8%) students practiced moderate physical mobility with a mean MET of 1260.9, and only 28 (17.7%) students practiced high levels of physical mobility with a mean MET of 5250.5, among 158 study populations. Conclusion: The majority of AHE students have changed their physical mobility behaviors, according to the survey. In addition, the survey discovered that a higher percentage of pupils were physically inactive, putting them at risk of acquiring an illness at a young age.

TL;DR: In this paper, the authors analyzed 105,529 U.S. civil aviation strike records from 1990 to 2012 in the FAA's National Wildlife Strike Database to examine patterns of collisions involving unidentified birds.
Abstract: A primary concern for human-wildlife interactions is the potential impacts resulting from wildlife (primarily birds) collisions with aircraft. The identification of species responsible for collisions with aircraft is necessary so that airport management can develop effective strategies to reduce strikes with those species. Of particular importance in developing such strategies is the identification of regional, seasonal, and temporal patterns in collisions with unidentified bird species that may limit the effectiveness of regional habitat management to reduce bird strikes. The authors analyzed 105,529 U.S. civil aviation strike records from 1990 to 2012 in the FAA's National Wildlife Strike Database to examine patterns of collisions involving unidentified birds. Factors that affected identification were airport certification class, FAA region, mass of struck species, state species richness (if damage was reported), and interactive effects between the last four factors. Identification varied by region and declined with increasing species richness; this identification was greater for general aviation (GA) airports and the mass of struck species, especially when damage was reported. Species identification might be improved by increasing reporting efforts relative to species richness, especially by GA airport managers and operations staff, who may have a higher propensity of reporting bird strikes, and by collecting more field-based data on avian populations. The results can provide guidance for the development of airport management and personnel training.

TL;DR: It is drawn that the relevant analysis/simulation data could be submitted to engine certification administration as key documents, and the structural safety analysis and assessment method of turbofan engine due to bird ingestion could be applied as analysis and prediction work in the engine bird ingestion certification.
Abstract: The high bypass ratio turbofan engine’s load-carrying structure transient response during bird ingestion was analyzed in accordance with the engine bird ingestion certification regulations, the principles of structural safety assessment were represented, and the structural safety analysis and assessment method of Turbo-Fan engine during bird ingestion were proposed. A high bypass ratio turbofan engine’s FEM was established and verified the rationality when its’ operation. Large bird ingestion into an engine’s procedure was conducted, the dynamic responses of key components on engine’s load-carrying structures during the bird ingestion were discussed, and the safety assessment consequence was obtained. We draw a conclusion that the relevant analysis/simulation data could be submitted to engine certification administration as key documents, the structural safety analysis and assessment method of turbofan engine due to bird ingestion could be applied as analysis and prediction work in the engine bird ingestion certification.

TL;DR: In this paper, the authors conducted a descriptive analysis of the recognized efficacy of yoga therapy on psychological variables in male persons with diabetic peripheral neuropathy (DPN) in Chengalpattu district, Tamil Nadu in India.
Abstract: The purpose of this study was to conduct a descriptive analysis of the recognized efficacy of yoga therapy on psychological variables in male persons with diabetic peripheral neuropathy (DPN). The sources of stress among person at 30 males with diabetic peripheral neuropathy were chosen for the study from the Chengalpattu district, Tamil Nadu in India were researched. To determine how stress sources are received by male persons with diabetic peripheral neuropathy (DPN). Studies on DPN participants have examined important psychological variables such as Stress and Anxiety. When receiving yoga therapy, Participants with diabetic peripheral neuropathy had improved Mind function and decreased their DPN level: symptom Stress and Anxiety levels among patients with diabetic peripheral neuropathy (DPN). The Participants were given a Perceived Stress Scale (PSS) and Generalized Anxiety Disorder (GAD-7) questionnaire. The PSS had ten objects rated on a 5-point scale, with 0 being the least stressful and four being the most stressful, and The GAD had seven objects rated on a 4-point scale, with 0 being the least Anxiety and 3 being the most Anxiety. Thirty males with diabetic peripheral neuropathy were chosen for the study randomly; they were between the ages of 35 and 70. Two groups were formed from the selected subjects. There were fifteen in each group. one underwent experimental groups(n=15) another underwent control group (n=15). Group- I received a Yoga therapy practice, and Group II underwent it without any practice. The 12-week training period, six days per week, an hour in the morning. To determine the way to deal with stress through Yoga. This study showed that individuals who participated in the yoga module performed better than Control Group II. Yoga Therapy performed much better in Experimental Group I. After practising Yoga for 12 weeks, the experimental group shows better results in psychological characteristics. According to our data, the Yoga practice group benefited more than the control group. The experimental group was significantly less Stressed and Anxiety. On the other hand, the control group showed a modest increase but no improvement. Our data support this notion. Improved mindfulness, which includes specific components for processing experience, being less self-critical and empathetic to themselves, and not over-identifying with Stress and Anxiety, was connected to greater impact in the Yoga practice group. This research study reveals that Yoga Therapy was a significantly more effective treatment for DPN.
