Study of Upper Critical Magnetic Field of Superconducting HoMo6Se8  [PDF]
Tadesse Desta, Pooran Singh, Gebregziabher Kahsay
World Journal of Condensed Matter Physics (WJCMP) , 2015, DOI: 10.4236/wjcmp.2015.53013
Abstract: This work focuses on the study of mathematical aspects of upper critical magnetic field of superconducting HoMo6Se8. At zero external magnetic field, HoMo6Se8 was found to undergo a transition from the normal state to the superconducting state at 5.6 K and returned to a normal but magnetically ordered state between the temperature range of 0.3 K and 0.53 K. The main objective of this work is to show the temperature dependence of the upper critical magnetic field of superconducting HoMo6Se8 by using the Ginzburg-Landau (GL) phenomenological Equation. We found the direct relationship between the GL coherence length (ξGL) and penetration depth (λGL) with temperature. From the GL Equations and the results obtained for the GL coherence length, the expression for upper critical magnetic field (Hc2) is obtained for the superconducting HoMo6Se8. The result is plotted as a function of temperature. The graph shows the linear dependence of upper critical magnetic field (Hc2) with temperature (T) and our finding is in agreement with experimental observations.

Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.46126
Abstract: Linear Least Square (LLS) is an approach for modeling regression analysis, applied for prediction and quantification of the strength of relationship between dependent and independent variables. There are a number of methods for solving the LLS problem but as soon as the data size increases and system becomes ill conditioned, the classical methods become complex at time and space with decreasing level of accuracy. Proposed work is based on prediction and quantification of the strength of relationship between sugar fasting and Post-Prandial (PP) sugar with 73 factors that affect diabetes. Due to the large number of independent variables, presented problem of diabetes prediction also presented similar complexities. ABS method is an approach proven better than other classical approaches for LLS problems. ABS algorithm has been applied for solving LLS problem. Hence, separate regression equations were obtained for sugar fasting and PP severity.

Efficacy of casein phosphopeptide-amorphous calcium phosphate to prevent stain absorption on freshly bleached enamel: An in vitro study
Singh Raghuwar,Ram Sabita,Shetty Omkar,Chand Pooran
Journal of Conservative Dentistry , 2010,
Abstract: Background: Teeth when subjected to bleaching bring about the desiccation of the enamel, making it more susceptible to stain absorption. While subjecting the freshly bleached enamel surface to various surface treatments of Fluoride and Casein Phosphopeptide - Amorphous Calcium phosphate (CPP-ACP) brought about the reduction in stain absorption, which is assessed in this study. Aims: The study aims to evaluate the tea stain absorption on freshly bleached enamel surface of extracted human teeth with varied surface treatment. The stain absorption was evaluated at the end of one hour and 24 hours post bleaching. Materials and Methods: Forty extracted human permanent maxillary central incisors were subjected to bleaching with 10% carbamide peroxide for eight days. They were divided into four groups of 10 each. Group I was control group. Group II was immersed in tea solution without surface treatment, while Group III and IV were immersed in tea solution with surface treatment of topical Fluoride and CPP-ACP respectively. Spectrophotometer was used for color analysis. Results: Surface treatment with CPP-ACP and topical fluoride on freshly beached enamel surface, significantly reduced the stain absorption. Conclusion: Remineralizing agents reduce stain absorption after tooth bleaching.
Collarless metal ceramic restorations to obscure the umbrella effect
Afroz Shaista,Chand Pooran
Indian Journal of Dental Research , 2010,
Abstract: Esthetics with porcelain fused to metal restoration in the anterior region can be adversely affected due to the inadequate teeth preparations and design of the prosthesis. We presented here a case report where esthetics was compromised due to darkening of the interdental papilla and marginal gingival and overcontoured restorations in relation to porcelain fused to metal restorations. Good esthetic results were obtained by using basic principles of tooth preparation and using collarless metal ceramic restorations.

Abstract: Chickpea ( Cicer arietinum L.) is known to be sensitive to many herbicides and, therefore, choices for using post-emergence herbicides for weed control are limited. The present study was aimed at identifying sources of tolerance to two herbicides with different modes of action (imazethapyr—amino acid synthesis inhibitor; and metribuzin—photosynthesis inhibitor) for use in breeding herbicide tolerant cultivars. Screening of 300 diverse chickpea genotypes (278 accessions from the reference set and 22 breeding lines) revealed large genetic variations for tolerance to herbicides imazethapyr and metribuzin. In general, the sensitivity of the genotypes to metribuzin was higher compared to that for imazethapyr. Several genotypes tolerant to metribuzin (ICC 1205, ICC 1164, ICC 1161, ICC 8195, ICC 11498, ICC 9586, ICC 14402 ICC 283) and imazethapyr (ICC 3239, ICC 7867, ICC 1710, ICC 13441, ICC 13461, ICC 13357, ICC 7668, ICC 13187) were identified, based on average herbicide tolerance scores from two experimental locations each. The herbicide tolerant lines identified in this study will be useful resources for development of herbicide tolerant cultivars and for undertaking genetic and physiological studies on herbicide tolerance in chickpea.

Pooran Golkar,Ahmad Arzani,Abdolmajid M. Rezaei
International Journal of Molecular Sciences , 2011, DOI: 10.3390/ijms12042664
Abstract: Safflower ( Carthamus tinctorious L.) is an oilseed crop that is valued as a source of high quality vegetable oil. The genetic diversity of 16 safflower genotypes originated from different geographical regions of Iran and some with exotic origin were evaluated. Eight different seed quality-related traits including fatty acid composition of seed oil (stearic acid, palmitic acid, oleic acid and linoleic acid), the contents of, oil, protein, fiber and ash in its seeds, as well as 20 inter-simple sequence repeat (ISSR) polymorphic primers were used in this study. Analysis of variance showed significant variation in genotypes for the seed quality-related traits. Based on ISSR markers, a total of 204 bands were amplified and 149 bands (about 70%) of these were polymorphic. Cluster analysis based on either biochemical or molecular markers classified the genotypes into four groups, showing some similarities between molecular and biochemical markers for evaluated genotypes. A logical similarity between the genotype clusters based on molecular data with their geographical origins was observed.

Research in Plant Biology , 2011,
Abstract: The F1 and F2 progenies of the eight-parent diallel crosses were used to investigatethe mode of inheritance of harvest index (HI) (%) in safflower (Carthamus tinctorius L.)seeds. The results indicated significant differences among the parents for general (GCA)in two evaluated generations. Specific combining ability (SCA) was significant in F1generation. Furthermore, the estimates of genetic variance components and predictabilityfactor (PF) proposed the more importance of additive genetic effects that contribute togenetic variation in harvest index. The overall results indicated that C4110 was the bestparental genotype for increasing HI (%). Also, superior crosses of K21× 22-191 (F1generation) and 22-191×C4110 (F2 generation) could be employed for the production ofhigh seed yielding safflower lines in breeding programs.

Abstract: Genetics of agronomic traits in safflower was determined using 6×6 full diallel population. Data were recorded on days to flowering, days to maturity, plant height, primary branches per plant, head diameter, number of heads per plant, number of seeds per head, 1000-seed weight and seed yield per plant. Variance components showed that days to maturity and heads per plant were largely controlled by dominance gene effects, whereas 1000-seed weight, plant height and seeds per head were governed by additive type of gene action. The results also revealed both additive and non-additive types of gene actions for remaining traits. The significant mean squares of reciprocal crosses for days to flowering, head diameter, number of seeds per head, 1000-seed weight and seed yield per plant suggested that maternal inheritance also played an important role in the inheritance of these traits. Significant general combining ability for yield revealed that genetic improvement through accumulation of desirable alleles from parents in the target genotype using appropriate selection methods would be desirable in safflower.
