    We present a model independent method to test the consistency between cosmological measurements of distance and age, assuming the distance duality relation. We use type Ia supernovae, baryon acoustic oscillations, and observational Hubble data, to reconstruct the luminosity distance D_L(z), the angle averaged distance D_V(z) and the Hubble rate H(z), using Gaussian processes regression technique. We obtain estimate of the distance duality relation in the redshift range 0.1<z<0.73 and we find no evidence for inconsistency between the data sets used.Comment: 5 pages, 1 pdf figure, minor revision, accepted for publication in Physics Letters

    Background: The major part of demand for blood in India has been meeting through voluntary blood donations. The healthy, active and receptive huge student population is potential blood donors to meet safe blood requirements. However, there is a paucity of studies on awareness and attitude among health science students on voluntary blood donation. Objective: The objective of this study was to determine the knowledge and attitude about blood donation among health science students. Methods: A cross-sectional study was conducted among 410 health sciences students from different streams in a University campus of South India through a structured survey questionnaire in the year 2009. Results: The overall knowledge on blood donation was good, but majority (62%) of students never donated blood. Knowledge level was found highest among allied health science (53.1%) and lowest among pharmacy students (20.7%). ‘Feeling of medically unfit’ and ‘never thought of blood donation’ were the major reasons for not donating blood. A significant association was observed between different streams of students and levels of knowledge and attitude about blood donation. Conclusion: This study elicits the importance of adopting effective measures in our campuses to motivate about voluntary blood donation among students

    Science could be best defined as pure unbiased knowledge which possess a set of concrete rationale which when pertinently applied in accordance to the circumstance, would yield accurate intended results permanently. Ayurveda is such a Science of life which encompasses in-depth scientific theorems and principles which are evolved by close and constant experimentation in human beings in multiple ways (the methodologies of which are technically described in medical treatises) and best scientifically validated and approved constantly by the experts for the last many centuries. For this reason, it is undoubtedly clear that this scientifically validated medical theories and principles which are verified successful in every era is the best pertinent evidence base to precisely guide ayurvedic medical practice and research
