Abstract

Advances in nano-fabrication techniques has made it feasible to observe damping phenomena beyond the linear regime in nano-mechanical systems. In this work, we report cubic non-linear damping in palladium nano-mechanical resonators. Nano-scale palladium beams exposed to a $H_2$ atmosphere become softer and display enhanced Duffing non-linearity as well as non-linear damping at ultra low temperatures. The damping is highest at the lowest temperatures of $\sim 110\: mK$ and decreases when warmed up-to $\sim 1\textrm{ }K$. We experimentally demonstrate for the first time a temperature dependent non-linear damping in a nano-mechanical system below 1 K. It is consistent with a predicted two phonon mediated non-linear Akhiezer scenario for ballistic phonons with mean free path comparable to the beam thickness. This opens up new possibilities to engineer non-linear phenomena at low temperatures.

7. Public health surveillance of construction site injuries in Delhi, India, using the First Information Reports (FIRs) registered by Delhi police

Author

Yadav, S. S., Porter, J., Edwards, P., and Watson, S.

Abstract

Background: An injury surveillance system can inform strategies to reduce the incidence of injuries. Aim: To explore whether the First Information Reports (FIRs) of Indian police can form the basis of an unintentional injuries surveillance system. Methods: Initially, a systematic review of literature on "The use of police records for injury surveillance" was undertaken. Three different but related studies were then conducted. The Minimum Data Set (MDS) recommended for injury surveillance was identified in the first study; a tool for the extraction of data from FIRs was also developed, and its inter-rater reliability was assessed using Cohen's Kappa; the percentage availability of each MDS data item in the FIRs was calculated. The total numbers of fatal and nonfatal construction site injuries in the Delhi population in 2017 were estimated by applying the two-sample capture-recapture method in the second study. The third study describes the epidemiology of construction site injuries in Delhi between 2016 and 2018. Results: The systematic review of literature showed that police records are a potentially useful source of information on unintentional injuries. The first study identified 12 MDS data items for injury surveillance; FIRs were found to contain complete information on 5 MDS data items but for 7 MDS data items, information was less complete. The second study estimated that FIRs ascertained 37%, 42.6% and 30.2% of the estimated total, fatal and non-fatal construction site injuries respectively. The third study found that 1,227 construction workers sustained injuries in 939 construction site incidents. Male workers (87%) and workers in the age group of 22 to 44 years (58.77%) accounted for most of those injured. The risk of a fatal injury was higher in migrant workers. The nonfatal injury rate per 100,000 workers per year was almost 3 times higher in female workers (98.55; 95% CI 82.52 to 116.8) than in male workers (34.36; 95%CI 31.92 to 36.94). Workers were at higher risk of injury in the rainy season and during 12:00 to 16:00 hours. Electricians and plumbers were the trade groups at higher risk of injury. Construction sites of government companies, and construction through a construction company, and works related to water supply, road construction, and power generation/distribution works were associated with higher odds of fatal injuries. The head (including face and eyes) was most prone to injury. Conclusion: Information on injuries can be reliably extracted from FIRs, however FIRs occasionally have incomplete information on some of the MDS data items. Furthermore, any epidemiological estimates made using these data must be adjusted to allow for the approximately two-thirds of injuries not reported to the police. Enforcement of existing legal provisions and the training of police personnel could help to reduce the 'missingness' of MDS data items and help to improve the ascertainment of injuries by FIRs. Imputation of missing data may help to improve the system further.

19. Critical Analysis of Gurvadi Guna According to Hemadri- A Review Article.

Author

Gangwar, Akanksha, Yadav, S S, Gangwar, Akanksha, and Yadav, S S

Abstract

Introduction-The ancient philosophy of well-being and healing called  Ayurveda is the ‘Science of Life’, which has its roots back to the civilizations.  The gurvadi guna help us to put words to what we sense and feel. They are 10  pairs of opposite gunas. For example- heavy-light (guru-laghu), cold-hot  (shita-ushna), unctous-dry (snigdha-ruksha), etc. Some of them make perfect  sense in modern medicine too, as hot for fever or cracking skin would be dry  etc. The same concept can be used to find any balance in life.  Materials and Methods- Among all the samhitas of Ayurveda, the Acarya  Hemadri in his commentary, Ayurveda rasayana on Ashtang Hridaya; have  done the detailed analysis about gurvadi guna, which no one else has done.  These attributes can be seen as energies or forces in our environment and  within us.  Results- The exact estimation of predominance of guna leading to vitiation of  doshas helps us to understand the pathogenesis and treatment can be planned  with the help of opposite guna. The detailed discussion about each and every  guna helps to develop a better understanding and clarification of the concept.  Conclusion- It is important to estimate the hetus of every individual and  estimate the guna predominance out of it which leads to vitiation of doshas and generation of disease for proper diagnosis and effective treatment.  Appropriate knowledge of guna may help the practitioner to understand the  disease along with that the drugs used for the treatment would be well  understood at every minute level and prescribed.&nbsp

Abstract

Abundance of insect pollinators on rapeseed-mustard showed that bees were most abundant on Brassica rapa L. var. toria i.e. 15.15, 18.47, 21.02 and 15.11 bees/ m²/ 10 min and least abundant on Brassica nigra i.e. 8.43, 9.53, 11.30 and 8.47 bees/ m²/ 10 min at 1000 h, 1200 h, 1400 h and 1600 h, respectively. At 1000 h, Apis mellifera was observed as the most abundant pollinator (13.94 bees/ m²/ 10 min) followed by A. cerana (11.23 bees/ m²/ 10 min), A dorsata (10.50 bees/ m²/ 10 min) and A. florea (8.30 bees/ m²/ 10 min) and the same trend was also followed at 1200 h, 1400 h and 1600 h. The comparative mean abundance of Apis spp. on different varieties/ genotypes of rapeseed-mustard revealed that bees were most abundant on variety TH 68 (16.77 bees/ m²/ 10 min) and least abundant on Nigra (9.12 bees/ m²/ 10 min). Also A. mellifera had maximum (15.50 bees/ m²/ 10 min) mean comparative density across the varieties/genotypes followed by A. cerana (12.90 bees/ m²/ 10 min), A. dorsata (12.25 bees/ m²/ 10 min) and A. florea (9.37 bees/ m²/ 10 min). The activity of different honey bees varied with time i.e. maximum abundance of A mellifera, A. cerana, A. dorsata and A. florea was reported at 1200 to 1400 h and it was least abundant at 1000 h and 1600 h of the day.

Abstract

Introduction: In the year 2003, Joshi et al. developed a validated outcome assessment tool to measure the ureteral stent-related symptoms. The original English language Ureteral Stent Symptom Questionnaire (USSQ) has been validated in various languages worldwide. Our objective was to develop the USSQ in Hindi, a commonlyused language in India, by validating it in patients undergoing ureteroscopic lithotripsy. Materials and Methods: A final Hindi version of the USSQ was derived from the original English version to apply to the study population by translation, back translation, and face-to-face interviews. The Hindi and English versions were completed by 70 patients undergoing ureteroscopic lithotripsy with stent in situ, on postoperative days 7 and 8, and 4 weeks after stent removal. Similarly, discriminant validity was checked among 50 healthy individuals. A detailed statistical analysis was used to correlate results (Cronbach's α coefficient, Spearman's correlation, and Mann–Whitney U-test). Results: A total of 70 patients were enrolled in the study and 61 completed the final assessment. The median age was 35 years (range: 18–60 years). The USSQ domain scores with the stent in situ were higher than poststent status. The test–retest reliability checked by Cronbach's α coefficient (>0.44) and Spearman's correlation coefficient (>0.44) were acceptable to good. We found high discriminant validity of the questionnaire between patients with stent and the healthy controls (P < 0.05). Conclusion: Our results demonstrate satisfactory validity for the Hindi version of the USSQ for the assessment of quality of life in patients with stent. This is ready for application in the clinical studies and the future stent-related research in Hindi language.

Abstract

With increasing globalization and industrialization, the life of human beings  has become much more sedentary, technology dependent and full of rush and  hustle because of which humans are gradually becoming unhealthier and more  diseased than ever before. Today, everyone is in hurry so they want everything  to be quick and speedy. They don’t have time to spend upon thinking about  eating healthy and lead a healthy lifestyle; which eventually made them fell ill  and get various kinds of diseases. Vyadhikshamatwa is a simple term which  means body’s own capacity to resist various kind of diseases. It is related to  bala as well as ojas as mentioned in ayurveda. Bala is characteristic feature of  healthy physical and mental state of body. As the aim of ayurveda is to make  an unhealthy person disease free and to maintain the health of a healthy person.  So, by choosing a healthy diet and lifestyle one can not only become disease  free but can also lead a long and healthy life as well. Various bala, ojas and  vyadhikshamatwa promoting factors are mentioned in Ayurvedic texts which  acts directly or indirectly upon human body. This article is the compilation of  bala, ojas and vyadhikshamatwa promoting factors &nbsp

Abstract

Background: In conventional agriculture, expensive phosphatic fertilizers were applied in huge quantities to reduce phosphorus deficiency in mungbean. Disproportionate application of these chemical fertilizers over long periods has damaged the natural properties of soils by killing soil micro flora and fauna, leading to reduced agricultural production. Sustainable agriculture based on organics and biological fertilizers is an effective solution for overcoming these problems. Therefore, keeping the above information in view, the present study was undertaken to assess the effect of PROM and microbial inoculants on the growth and yield of mungbean. Methods: In this field-laboratory experiment which was conducted at agronomy farm of Sri Karan Narendra Agriculture University, Jobner, during Kharif season of 2019, 12 treatments involving control, PROM, PSB, VAM, Pseudomonas fluorescens (PF) and their respective combinations were included which was laid out in randomized block design with three replications. The collected samples were determined for growth and yield attributes in the field and laboratory. Result: The results showed that combined application of PROM+PSB+VAM+PF reported the maximum values of most of the growth and yield attributing characters i.e. plant height, number of branches/plant, dry matter accumulation, total and effective number of root nodules per plant, fresh and dry weight of nodules per plant, crop growth rate, chlorophyll content, number of pods/plant, number of seeds/pod, test weight, seed, straw and biological yield of mungbean as compared to other combinations and control, but it was at par with PROM+PSB+VAM.

Abstract

This paper aims to investigate numerically linear stable waves at low wave steepness in shallow water using ANSYS Fluent software. The authors mainly determined how, when, and where a linear wave will reach its stable state in shallow water. The finite volume method is used to solve the Navier-Stokes equations. The inflow velocity method and the Dirichlet boundary condition are used to generate a suitable linear wave. Numerical damping is used at the end of the tank to reduce the reflection of the wave. The accuracy and stability of the waves are judged under wave height variation between the CFD results and the analytical results. The test has been conducted in four different cases (Case 1, Case 2, Case 3, and Case 4). Wave evolution and particle velocity are obtained in the velocity field to understand the wave stability in the numerical wave tank. Numerical data are captured from the free surface to compare the surface profile and wave velocity. The results have revealed that the accuracy, stability, and consistency of the linear waves are in good agreement with the analytical solution. The relative error between the two results is 1.43% for Case 3. This research is a highly relevant source of information in realistic wave generation to design various practical systems such as wave energy converters, offshore marine structures, and many ocean engineering problems.
