Ab-Initio Structural Study of SrMoO3 Perovskite  [PDF]
Avinash Daga, Smita Sharma
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.312238
Abstract: The equilibrium crystal structure parameter and bulk modulus of the SrMoO3 perovskite has been calculated with ab-initio method based on density functional theory (DFT) using both local density approximation (LDA) and generalized gradient approximation (GGA). The corresponding total free energy along with its various components for SrMoO3 was obtained. The lattice parameter and bulk modulus calculated for SrMoO3 within LDA are 3.99 A and 143.025 GPa respectively whereas within GGA are 4.04 A and 146.14 GPa respectively, both agree well with the available experimental data. The total energy calculated within LDA and GGA is almost the same however lower results are obtained for GGA. All calculations have been carried out using ABINIT computer code.
First Principle Study of Cubic SrMO3 Perovskites (M = Ti, Zr, Mo, Rh, Ru)  [PDF]
Avinash Daga, Smita Sharma, K. S. Sharma
Journal of Modern Physics (JMP) , 2011, DOI: 10.4236/jmp.2011.28095
Abstract: Lattice parameter and corresponding total free energy have been computed for cubic SrMO3 perovskites (M = Ti, Zr, Mo, Rh, Ru) using the first principle approach within Density functional theory. The results have been calculated using local density approximation (LDA) method. It is found that the calculated lattice parameter for all transition metal oxides are in good agreement with the available experimental data. The total free energy corresponding to this lattice constant has been calculated along with different components of the total free energy. All these calculations have been carried out using ABINIT computer code.

Abstract: Bulk modulus & charge density of cubic SrMO3 perovskites (M = Ti, Zr, Mo, Rh & Ru) have been investigated systematically using the first principle density functional calculations. Local density approximation (LDA)method has been used to compute the two quantities for five perovskites. It is found that the calculated bulk modulus for all the transition metal oxides are in good agreement with the available experimental data and with other theoretical results previously reported in the literature. ABINIT computer code is used to carry out all the calculations. Charge density plots for all the five cubic SrMO3 perovskites have been drawn using MATLAB. The maximum and minimum values of charge density along with the corresponding reduced coordinates are reported for all the perovskites.
Genetic diversity among Indian phytopathogenic isolates of Fusarium semitectum Berkeley and Ravenel  [PDF]
Avinash Ingle, Mahendra Rai
Advances in Bioscience and Biotechnology (ABB) , 2011, DOI: 10.4236/abb.2011.23023
Abstract: We report total ten isolates of F. semitectum recovered from different hosts. Identity of these isolates was determined by morphological and cultural characteristics and confirmed by RAPD-PCR analysis using forty random primers. Morphologically all the ten isolates showed similarity, but based on RAPD-PCR analysis, these isolates can be categorized in three groups depending upon similarity co-efficient. Genetic similarity coefficients between pair wise isolates varied from 0.00 to 1.95 based on an unweighted paired group method of arithmetic average (UPGMA) cluster analysis. RAPD-PCR technique can be used as an important tool for the genetic differentiation among isolates of F. semitectum.
Resistance Training in Parkinson’s Disease: A Longitudinal Study  [PDF]
Luca Beratto, Federico Abate Daga, Ruben Allois, Massimiliano Gollin
Advances in Parkinson's Disease (APD) , 2017, DOI: 10.4236/apd.2017.62007
Abstract: Objective: The objective of this study was to verify the effect of micro-loads and elastic bands exercise program in a group of patients with Parkinson’s disease (PD). Methods: Twenty-one people with PD, participated in this study. All participants were able to walk unassisted, and their disability score using the Hoehn & Yahr scale was 2 ± 0.5. Subjects were randomly assigned to micro-loads group (11 subjects, age 69 ± 10 years; weight 72 ± 12 kg, height 171 ± 7 cm) or to elastic band group (9 subjects, age 70 ± 11 years; weight 69 ± 15 kg and high 169 ± 9 cm). Both groups performed two sessions of physical activity per week during a period of 5 months. Subjects were evaluated on flexibility with sit and reach test; the body balance with stabilometric platform, useful to evaluate the center of pressure (COP); the Spinal Mouse to assess the column shape and the sit to stand test to measure the strength performance of lower limbs. Tests were three times during the training period: after the first and the third month of physical activity and at the end of the training period. Results: Data showed a statistically significant variation in the sit to stand test in the EG group (T0 vs T2; Anova, p < 0.001, post hoc, p < 0.01, +19%). Conclusion: Both micro-loads and elastic band exercises were well-tolerated. Elastic bands exercises produced a significant improvement in the lower limbs muscles performance.
Controlled Growth of CdS Nanocrystals: Core/Shell viz Matrix  [PDF]
Prinsa. verma, Avinash C Pandey
Journal of Biomaterials and Nanobiotechnology (JBNB) , 2011, DOI: 10.4236/jbnb.2011.24050
Abstract: The ability to precisely control the size of semiconductor nanocrystals can create an opportunity for producing functional materials with new properties, which are of importance to applications such as Light emitting diodes, biomedical diagnosis, solar cells, and spintronics. And size of nanoparticle can be controlled with efficient capping agent. For the same purpose we reported, two types of capping, one will lead to nanomatrix and other to Shelled nanostructures. Enhancement in emission intensity observed with Shell nanostructures compare to matrix. PVP is used to control the particle size, to prevent agglomeration and making thin films. A blue shift in energy level at the nanoscale is demonstrated by optical absorption. Electron microscopy studies with an SEM and TEM show a particle size of 10 nm and 15 nm. We also investigated the particle size distribution of nanoparticles by small angle scattering (SAXS) study.

Phase separation transition of reconstituting k-mers in one dimension
Bijoy Daga,P. K. Mohanty
Statistics , 2014, DOI: 10.1088/1742-5468/2015/04/P04004
Abstract: We introduce a driven diffusive model involving poly-dispersed hard k-mers on a one dimensional periodic ring and investigate the possibility of phase separation transition in such systems. The dynamics consists of a size dependent directional drive and reconstitution of k-mers. The reconstitution dynamics constrained to occur among consecutive immobile k-mers allows them to change their size while keeping the total number of k-mers and the volume occupied by them conserved. We show by mapping the model to a two species misanthrope process that its steady state has a factorized form. Along with a fluid phase, the interplay of drift and reconstitution can generate a macroscopic k-mer, or a slow moving k-mer with a macroscopic void in front of it, or both. We demonstrate this phenomenon for some specific choice of drift and reconstitution rates and provide exact phase boundaries which separate the four phases.
Networking in medical education: Creating and connecting
Supe Avinash
Indian Journal of Medical Sciences , 2008,
Abstract: Social networking is being increasingly used as a tool of choice for communications and collaborations in business and higher education. Learning and practice become inseparable when professionals work in communities of practice that create interpersonal bonds and promote collective learning. Individual learning that arises from the critical reconstruction of practice, in the presence of peers and other health professionals, enhances a physician′s capability of clinical judgment and evidence-based practice. As such, it would be wise for medical schools, whose responsibility it is to prepare students to make a transition to adult life with the skills they need to succeed in both arenas, to reckon with it.
