An Application of the ABS Algorithm for Modeling Multiple Regression on Massive Data, Predicting the Most Influencing Factors  [PDF]
Soniya Lalwani, M. Krishna Mohan, Pooran Singh Solanki, Sorabh Singhal, Sandeep Mathur, Emilio Spedicato
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.
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.
High Dose Methylprednisolone: Effective in Pregnancy Associated Post-splenectomy Refractory Chronic Immune Thrombocytopenic Purpura
A Singh,A Solanki
Nepal Journal of Obstetrics and Gynaecology , 2014, DOI: 10.3126/njog.v9i1.11192
Abstract: We present a case of 23 years multigravid woman (G2P0+1) with chronic idiopathic thrombocytopenic purpura (ITP), refractory to treatment in forms of oral steroid, dapsone, azathioprine and splenectomy. She presented to the hospital in third trimester of pregnancy, with reduced platelet counts and purpuric rashes over abdomen and both upper extremeties. There was a past history of spontaneous abortion at 18 weeks. The patient responded to intravenous high dose methylprednisolone (HDMP) infusion leading to delivery of full term male baby. The baby also required treatment for thrombocytopenia with intravenous immunoglobulin (IVIG). This case lays down the importance of HDMP in form of using it effectively in managing acute crisis of low platelet counts in pregnant patients with ITP refractory to splenectomy.
Development of Impedimetric Biosensor for Total Cholesterol Estimation Based on Polypyrrole and Platinum Nanoparticle Multi Layer Nanocomposite  [PDF]
K. Singh, Ruchika Chauhan, Pratima R. Solanki, Tinku Basu
International Journal of Organic Chemistry (IJOC) , 2013, DOI: 10.4236/ijoc.2013.34038
Abstract:

A novel impedimetric biosensor was fabricated for total cholesterol sensing based on platinum nanoparticle and polypyrrole multilayer nanocomposite electrode. The Pt nanoparticles (PtNP) electrochemically deposited between two polypyrrole layers on indium tin oxide (ITO) glass plates (PtNP/PPY/ITO) have offered high-electroactive surface area and favourable microenvironment for immobilization of cholesterol esterase (ChEt) and cholesterol oxidase (ChOx) resulting in enhanced electron transfer between the enzyme system and the electrode. Impedimetric response studies of the ChEt-ChOx/PtNP/ITO nanobioelectrode exhibit improved linearity (2.5 × 10-4 to 6.5 × 10-3 M/l), low detection limit (2.5 × 10-4 M/l), fast response time (25 s), high sensitivity (196 Ω/mM/cm-2) and a low value of the Michaelis-Menten constant (Km, 0.2 M/l) with a regression coefficient of 0.997.

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.
Beta-Lactamase Inhibitory Potential and Antibacterial Potentiation of Certain Medicinal Plants and Extracts against Extended Spectrum Beta-Lactamase Producers
Shakti Singh Solanki,Selvanayagam M
Advanced Biotech , 2013,
Abstract: Beta-lactamase inhibitory potential of fifteen plants was checked by beta-lactamase enzyme inhibition assay wherein inhibition of commercial beta-lactamase by their extracts was determined using a chromogenic substrate. These plant extracts showed considerable beta-lactamase inhibition. All these plant extracts were further checked for their inhibition of Extended Spectrum Beta-lactamase in the screening assay. Eight of the plant extracts showed potentiation of cephalosporins against the Extended Spectrum Beta-lactamase producing Klebsiella pneumoniae strain and were checked for their beta-lactamase (especially Extended Spectrum Beta-lactamase) inhibitory potential against a panel of beta-lactam resistant Gram negative bacterial strains (mainly Extended Spectrum Beta-lactamase producers) and few beta-lactam resistant Gram positive bacterial strains. Four of the plants showed substantial potentiation of the beta-lactams against the beta-lactam resistant bacterial strains and seem to have potential as beta-lactamase inhibitors (including against Extended Spectrum Beta-lactamase producers). The presence of beta-lactamase inhibitory potential in the studied plant extracts warrants further efforts in regard to purification and isolation of bioactive compounds from their extracts for probable development of new beta-lactamase inhibitors.

ESTIMATION OF FINITE POPULATION MEAN USING RANDOM NON–RESPONSE IN SURVEY SAMPLING
Housila P. Singh,Ramkrishna Singh Solanki
Pakistan Journal of Statistics and Operation Research , 2011, DOI: 10.1234/pjsor.v7i1.140
Abstract: This paper consider the problem of estimating the population mean under three different situations of random non–response envisaged by Singh et al (2000). Some ratio and product type estimators have been proposed and their properties are studied under an assumption that the number of sampling units on which information can not be obtained owing to random non–response follows some distribution. The suggested estimators are compared with the usual ratio and product estimators. An empirical study is carried out to show the performance of the suggested estimators over usual unbiased estimator, ratio and product estimators. A generalized version of the proposed ratio and product estimators is also given.
An alternative procedure for estimating the population mean in simple random sampling
Housila P. Singh,Ramkrishna Singh Solanki
Pakistan Journal of Statistics and Operation Research , 2011, DOI: 10.1234/pjsor.v8i1.252
Abstract: This paper deals with the problem of estimating the finite population mean using auxiliary information in simple random sampling. Firstly we have suggested a correction to the mean squared error of the estimator proposed by Gupta and Shabbir [On improvement in estimating the population mean in simple random sampling. Jour. Appl. Statist. 35(5) (2008), pp. 559-566]. Later we have proposed a ratio type estimator and its properties are studied in simple random sampling. Numerically we have shown that the proposed class of estimators is more efficient than different known estimators including Gupta and Shabbir (2008) estimator.
