Burning rate and other characteristics of strontium titanate （SrTiO3） supplemented AP/HTPB/Al composite propellants

引用

Defence Technology（防务技术） 2019年第3期15卷 313-318页

作者： Sunil Jain Garima Gupta Dhirendra R. Kshirsagar vrushali H. Khire Balasubramanian Kandasubramanian HEMRL Sutarwadi Pune India a DIAT Girinagar Pune India

In a quest of search for a new burning rate modifier for composite propellant, strontium titanate (SrTiO3), a perovskite oxide has been chosen for evaluation in a composite propellant formulation based on its other catalytic applications. Initially, SrTiO3 was characterized for particle size, morphology and material/ phase identification (using XRD). By varying SrTiO3 content in a standard composite propellant, different compositions were prepared and their performance and processing parameters like the end of mix (EOM) viscosity, mechanical properties, density, burning rate, pressure exponent (n-value), etc. were measured. The results reveal that 2% SrTiO3 causes more than 12% enhancement in propellant burning rate (at 70 ksc pressure) in comparison to the standard propellant composition. The pressure exponent also increases to 0.46, whereas the standard composition was having its value as 0.35.

Trends of Seroprevalence, Epidemiology and Clinical Presentation of HIV in North India: A Tertiary Care Hospital Based Study

World Journal of AIDS 2016年第2期6卷 54-58页

作者： Varun Goel Dinesh Kumar vrushali Patwardhan Veena Balooni Shalini Singhal Sarman Singh Clinical Microbiology and Molecular Medicine Department of Laboratory Medicine All India Institute of Medical Sciences (AIIMS) New Delhi India

Introduction: HIV infection represents a major public health problem for both developing and developed countries as it has grown to global pandemic. Spectrum of clinical presentation of HIV can greatly vary with geopolitical, socioeconomic and cultural environment. Aims: The aim of this study was to estimate the prevalence, socio-demographic conditions, clinical presentations, opportunistic infections and the possible associated risk factors for acquiring HIV infection. Materials and Methods: An observational prospective study was conducted from January 2010 to December 2014 at our centre situated in north India. As per the strategy and policy prescribed by NACO, tests were performed on the serum samples. Results: Out of the total 35369 clients tested for HIV infection, 292 were found to be HIV-1 seropositive. Two HIV-2 cases were found among the studied population. The seroprevalence of HIV was found to be 0.83% (294/35369). Mean age of the study group was 30 ± 5.65 (range: 02 - 80) years. Overall positivity rates among attendees were found to be 0.97% (138/14098), 0.96% (35/3610), 0.82% (7/850), 0.78% (22/2810) and 0.65% (92/14001) in the years 2010, 2011, 2012, 2013 and 2014 respectively. Heterosexual route of transmission was the major route of infection in 78.2 % patients. At the time of presentation, it was observed that Tuberculosis (14.9%) was the most common opportunistic infection. Conclusion: The study shows that there is a decreasing trend in the HIV prevalence in North India. However, the number of HIV cases is still significant and suggests the need for focused prevention efforts in high-risk groups.

Characterization of chickpea germplasm conserved in the Indian National Genebank and development of a core set using qualitative and quantitative trait data

The Crop Journal 2016年第5期4卷 417-424页

Chickpea is the third most important pulse crop as a source of dietary protein. Ever-increasing demand in Asian countries calls for breeding superior desi-type varieties, in turn necessitating the availability of characterized germplasm to breeders. The Indian National Genebank,located at the National Bureau of Plant Genetic Resources, New Delhi, conserves 14,651 accessions of chickpea. The entire set was characterized in a single large-scale *** variation was observed for eight quantitative and 12 qualitative agro-morphological traits. Allelic richness procedure was employed to assemble a core set comprising 1103 accessions, 70.0% of which were of Indian origin. Comparable values of total variation explained by the first three principal components in the entire collection(51.1%) and the core(52.4%)together with conservation of nine pairwise r values among quantitative traits in the core collection and a coincidence rate around 99.7% indicated that the chickpea core was indeed an excellent representation of the entire chickpea collection in the National Genebank. The chickpea core exhibited greater diversity than the entire collection in agro-morphological traits, as assessed by higher variance and Shannon–Weaver diversity indices, indicating that the chickpea core maximized the phenotypic diversity available in the Indian chickpea germplasm. The chickpea core, comprising mainly indigenous desi genotypes, is expected to be an excellent resource for chickpea breeders. Information on the chickpea core can be accessed at http://***/pgrportal.
