Matter-positronium interaction: An exact diagonalization study of the He atom - positronium system

The many-body system comprising a He nucleus, three electrons, and a positron has been studied using the exact diagonalization technique. The purpose has been to clarify to which extent the system can be considered as a distinguishable positronium (Ps) atom interacting with a He atom and, thereby, to pave the way to a practical atomistic modeling of Ps states and annihilation in matter. The maximum value of the distance between the positron and the nucleus is constrained and the Ps atom at different distances from the nucleus is identified from the electron and positron densities, as well as from the electron-positron distance and center-of-mass distributions. The polarization of the Ps atom increases as its distance from the nucleus decreases. A depletion of the He electron density, particularly large at low density values, has been observed. The ortho-Ps pick-off annihilation rate calculated as the overlap of the positron and the free He electron densities has to be corrected for the observed depletion, specially at large pores/voids.Comment: 18 pages, 8 figure

Conservation of high Phosphorous high Manganese ores by Sintering of Dephosphorised concentrate

The ores of manganese enjoy a high order of import- ance since no quality steel can be produced without the addition of small amounts of manganese. In view of its economic importance it becomes imperative to take stock of the facts about this mineral in a comprehensive manner. According to an IBM estimate, the recoverable rese-rves of manganese ore as on 1-1-1983 are 138.00 million tonnes comprising 18 million tonnes in measured category 32.00 million tonnes in indicated category and 88.00 million tonnes in inferred category

TO STUDY EFFICACY OF COMPREHENSIVE DIABETES CARE (CDC) MANAGEMENT PROGRAM IN TYPE II DIABETIC OBESE PATIENTS: AN OBSERVATIONAL STUDY

Context: Diabetes mellitus (DM) contributes to a major chunk of morbidity, mortality, and healthcare cost on a global level. The prevalence of DM is rising alarmingly, worldwide and India. Comprehensive Diabetes Care (CDC) is a combination of Panchakarma and diet management.Aims: This study was conducted to evaluate the effect of CDC on Glycosylated hemoglobin (HbA1c), body mass index (BMI), body weight, abdominal girth and dependency on conventional therapy in DM Patients.Setting and Design: This observational study was conducted in July 2017, wherein the data of obese Type II DM patients (HbA1c >6.5%) who attended out-patient departments (OPDs) at Madhavbaug clinics in Maharashtra, India were identified.Materials and Methods: Data of patients who were administered CDC (60-75 minutes) with minimum 6 sittings over 90 days (± 15 days) were considered. Variables were compared between day 1 and day 90 of CDC.Results: Out of 27 patients, 22 were included for analysis, out of which 10 were males while 12 females. CDC showed significant improvement in HbA1c 1.1% (from 8.80 ± 0.93 to 6.98 ± 1.73; p<0.001), BMI by 2.66 (from 33.79 ± 3.80 to 31.13 ± 3.91, p< 0.001), weight by 6.56 kg (from 83.67 ± 11.28 to 77.11 ± 12.27, p<0.001). Abdominal girth (from 104.34 ± 9.74 to 96.97 ± 11.93; p<0.001), also showed significant reduction. Dependency on concomitant medicines was reduced, with the number of patients on no concomitant medicines increasing from 27% to 41%.Conclusion: Comprehensive Diabetes Care Management Program found to be efficacious; by reducing HbA1c, as well as reducing dependency on allopathic medications

Sintering characteristics of manganese ore fines from Balaghat and Ukwa mines of Manganese Ore (India) Limited

Indian manganese ore reserves are depleting very fast Manganese ore (India) Ltd. realised that utilisation of Manganese ore fines will pave the way for conservation of lumpy high grade manganese ore. Manganese ore fines generated at Balaghat and Ukwa mines of MOIL were subjected to sintering studies at the R&D Centre of Paramount Sinters Pvt. Ltd. The studies indicated that fluxed sinter with very good strength and porosity could be produced. The sinters showed a high degree of reduction and even metalization was noticed. The chemical and physical characteristics indicated that sinters can be used in ferro manganese furnaces. Advantages of using sinter in the ferro alloy manufacture has been highlighted in this report. The authors have conc-luded that from the point of view of conservation and reduction of manufacturing cost, sintering has a vital role to play in ferro alloy industries

Genome analysis of amaranths: determination of inter- and intra-species variations

Amaranths are an important group of plants and include grain, vegetable and ornamental types. Despite the economic importance of the amaranths, there is very little information available about the extent and nature of genetic diversity present in the genus Amaranthus at molecular level. We now report the randomly amplified polymorphic DNA (RAPD) profiles of different species of Amaranthus as well as different accessions of the species. These RAPD analyses have been carried out using 65 arbitrary sequence decamer primers. From the RAPD data, an UPGMA dendrogram illustrating the inter-as well as intra-species relationships has been computed. The putative hybrid origin of A.dubious from A. hybridus and A. spinosus is also ruled out by the RAPD data. The trends of species relationships amongst the amaranths determined by RAPDs is consistent with their cytogenetic and evolutionary relationships that have already been determined

Polymethyl Methacrylate as a Binder for Pyrotechnic Compositions

Studies on polymethyl methacrylate (PMMA) as a binder for igniter and delay compositions are reported. Igniter compositions based on magnesium and boron as fuels and potassium nitrate as oxidiser, delay compositions comprising ferrosilicon and red lead, have been investigated. These compositions were subjected to various tests, such as linear burning rate, sensitivity, calorimetric value, compatibility, pelleting properties, spark sensitivity, ignition temperatures and performance characteristics. The results indicate that the igniter compositions Mg:KNO/sub 3/:PMMA (42:50:8) and B:KNO/sub 3/:PMMA (30:70:10) as well as the delay composition comprising FeSi:Pb/sub 3/O/sub 4:PMMA (25:75:1) have improved properties and therefore could find practical applications
