Optimum sowing dates for soybean in Central India using CROPGRO and ClimProb symbiosis

The optimum sowing dates for soybean cv. Gaurav were derived for Jabalpur, Raipur and Gwalior in the state of Madhya Pradesh in central India. Dates were derived based on two strategies: (a) probabilities of rainfall and temperature events using ClimProb, a PC based software package, and (b) the CROPGRO Soybean v3.0 crop growth simulation model. In Madhya Pradesh, the optimum sowing dates for multiple cropping, with the first crop as soybean under rainfed conditions, are between weeks 25 and 27, while the optimum sowing dates for rainfed mono-cropping are between weeks 28 and 29

Effect of Summer Temperature on the Work Efficiency of Dentists

INTRODUCTION AND AIM: Environment is closely related to human health. While the effects of temperature on comfort are broadly recognized, the effects on worker productivity have received much less attention. Thus this research was planned to investigate the effects of heat stress on job satisfaction, job performance, occupational stress among dentists. MATERIALS AND METHOD: This research was designed to be cross-sectional in nature where a convenience sampling of 70 interns, 88 post-graduate students and 49 faculty members of IDS Bareilly were selected. Questionnaires were self-administered and contained twelve points for job satisfaction (Minnesota Satisfaction Questionnaire), thirteen points for occupational stress and twelve for job performance RESULTS: The subjects were moderately satisfied with their jobs, were less stressed and had a moderate job performance. After descriptive tests, the Chi-squared test,  Pearson and Spearman Correlation Coefficient was applied to test statistical significance and p value was set to be significant at p<0.5. DISCUSSION: The present study showed that most of the dentists (60.9%) had a high sense of heat and such results may be because of the current hospital framework which includes lack of air conditioners, continuous patient workload in hospital, high sense of heat among the dentists working in top floors etc. CONCLUSION: If effective prevention measures are taken in the hospitals, dentists may perform more efficiently and also the increase the job satisfaction

The Impact of Using Social Media on Dental Treatment: An Online Survey

INTRODUCTION: Social media is a mode of communication that allows a person to create and share information with others. Facebook, WhatsApp, Twitter, Google+, YouTube etc are some examples of social media applications and they allow people to communicate across the world. There is very less literature available that shows the effect of social media in esthetics in India. AIM: To conduct an online survey to see the impact of using social media on esthetic dental treatments. MATERIALS AND METHOD: 477 questionnaires were returned with responses and the data was entered into the MS excel sheet. Descriptive statistics was used for the frequency distribution and Chi Square was applied for the statistical relationship between male and female variables (at 5% significance). RESULTS:  Four hundred seventy seven participants responded to this study through online forms. Most of the participants belonged to the age group of 26-35 years (n=256), followed by 18-25 years (n= 137), 36-45 years and > 45 years (n= 55 & 29 respectively). The response of females was high (63.5%) when compared to males. CONCLUSION: Females tend to follow dentists more as compare to males on social media. In dental practice, social media has become a widely used for exchanging and obtaining information

Assessment of Knowledge and Attitude Towards Hepatitis B Infection Among Health-Care Professionals in A North Indian City

Introduction: Hepatitis B is an infection which occurs frequently worldwide. Hepatitis B virus is a DNA virus and is etiologically related to family Hepadnaviridae.Most of the cases of Hepatitis B virus infection do not have any symptoms when they are newly or chronically infected due to which there is silent spread of the infection which later causes serious liver disease. Incidence of the Hepatitis B virus infection among health-care professionals has been estimated to be 2–4 times more as compared to the general population.Aims: to assess the knowledge and attitude towards Hepatitis B infection among medical, dental, and nursing students in Bareilly city.Settings and Design: A cross-sectional observational study was conducted among the medical and nursing students of Rohilkhand Medical College and Hospital and dental students of Institute of Dental Sciences, Bareilly.Method and Materials: A self-reported questionnaire was distributed among all the students of the study who were present at the day.Statistical analysis used: p-value was calculated using Kruskal Walli’s ANOVA test. A p-value of 0.05 or less was used as cut off level for statistical significance.Results: Total 222 students were selected out of which 60 were medical, 60 were dental and 102 were nursing. In our study medical students had better knowledge, attitude towards Hepatitis B infection than dental and nursing students.Conclusions: None of the students of medical, dental, and nursing were fully aware on all aspects of Hepatitis B Virus infection and the vaccination status was found to be unsatisfactory which increased the risk to acquire Hepatitis B infection

Multiaxial fatigue studies on carbon steel piping material of Indian PHWRs

The tests studies and analyses have been carried out in the area of “Multiaxial Fatigue” with an objective to improve the damage assessment methodologies and design rules. Nearly 50 numbers of fatigue tests were conducted on solid and tubular specimens of SA333Gr.6 material under pure axial, pure shear and combined axial-torsion in-phase/ out-of-phase loading combinations. A software has been developed for the evaluation of multiaxial fatigue damage for the analyses of tests data using different invariant fatigue models such as ASME Sec.III code procedures, von-Mises etc. The fatigue crack initiation life was predicted using the best fit axial fatigue life curve (without use of safety factors). These tests and their analyses have helped in understanding the fatigue failure behavior of piping material under complex cyclic loadings where the principal directions rotate during a loading cycle. The crack initiation angles have also been measured by analyzing the image of the tested specimens. The measured crack angles will help in validation of the critical plane based models

Fresh water influence on nutrient stoichiometry in a tropical estuary, southwest coast of India

Cochin backwaters, a micro tidal estuary, undergo a characteristic transformation from a river-dominated system during summer monsoon to a tide-dominant system during pre-monsoon season. The present study observes that as the river flow weakens after monsoon, the flushing of the estuary diminishes and the nitrogen and phosphorous loadings through anthropogenic activities (industries) and sediment re-suspension alter the nutrient stoichiometry substantially. The increased tidal activity during pre-monsoon changes the estuary into a vertically mixed, eutrophic and flow-restricted system supporting an enhanced organic production. This implies that monsoon-induced hydrology plays an important role in regulating the nutrients, secondary production and even the migrant fauna of the estuary. The system is delicately poised, as continuous release of pollutants including nutrients into this estuary would suppress fish and shell fish production, where only pollution tolerant species can exist

Genetic architecture and population structure of Oat Landraces (Avena sativa L.) using molecular and morphological descriptors

439-450Oat is grown as winter forage in India. It is a self-pollinated crop with less variability. However, the variation for different morphological traits in oat germplasm may be available at genotypic level. The present study was conducted to find out the genetic diversity among 24 oat landraces using 9 morphological traits and 24 SSR primers. Morphological data observed across the 24 landraces showed wide variation and grouped various landraces into two clusters. GFY and DMY were positively and significantly correlated with most of the traits studied. The molecular analysis using 24 SSR primers resulted amplification of 62 polymorphic alleles with an average of 2.58 alleles per primer. Size of amplified alleles ranged from 70 to 480 bp. Mean polymorphic information content was 0.42 showing moderate level of SSR polymorphism. Cluster analysis based on SSR data differentiated 24 oat landraces into three major clusters. Bayesian model-based STRUCTURE analysis assigned landraces into two clusters and showed the extent of admixture within individuals. Clustering pattern of oat landraces based on SSR marker profiles were different from that of morphometric traits. So, based on the pooled analysis at morphological and molecular level, the landraces IG-02-121, IG-02-129 and IG-02-113 were found superior for morphological traits as well as most distant among all the landraces under study. Hence, these landraces could be used in for future breeding programmes for genetic improvement in oats
