Solar Activity during the Rising Phase of Solar Cycle 24  [PDF]
Aradhna Sharma, S. R. Verma
International Journal of Astronomy and Astrophysics (IJAA) , 2013, DOI: 10.4236/ijaa.2013.33025

Solar activity refers to any natural phenomenon occurring on the sun such as sunspots, solar flare and coronal mass ejection etc. Such phenomena have their roots deep inside the sun, where the dynamo mechanism operates and fluid motions occur in a turbulent way. It is mainly driven by the variability of the sun’s magnetic field. The present paper studies the relation between various solar features during January 2009 to December 2011. A good correlation between various parameters indicates similar origin.

Vertical Decomposition Approach to Solve Single Stage Capacitated Warehouse Location Problem (SSCWLP)  [PDF]
Priyanka Verma, R. R. K. Sharma
American Journal of Operations Research (AJOR) , 2011, DOI: 10.4236/ajor.2011.13013
Abstract: Single Stage Capacitated Warehouse Location Problem (SSCWLP) has been attempted by few researchers in the past. These are Geoffrion and Graves [1], Sharma [2], Sharma [3] and Sharma and Berry [4]. In this paper we give a “vertical decomposition” approach to solve SSCWLP that uses Lagrangian relaxation. This way SSCWLP is broken into two versions of capacitated plant location problem (the CPLP_L and CPLP_R) by relaxing the flow balance constraints. For CPLP_R, we use well known Lagrangian relaxations given in literature (Christofides and Beasley [5] and Nauss [6]); and adopt them suitably for solving CPLP_L. We show theoretically in this paper that SSCWLP can be more efficiently solved by techniques of vertical decomposition developed in this paper than the method available in literature (Sharma and Berry [4]). Encouraging computational study is reported in this paper.
Clino-Pathological Features of Urinary Tract Infection in Rural India  [PDF]
Rutuja Raval, R. J. Verma, Hiten Kareliya
Advances in Infectious Diseases (AID) , 2015, DOI: 10.4236/aid.2015.54016
Abstract: The study was aimed to understand the clino-pathological characteristics of urinary tract infection along with the techniques used in diagnosis and treatment of the presenting infection. The study takes into consideration the various risk factors such as age, sex, and diabetes mellitus which can precipitate a urinary tract infection. The study was conducted at the Global Baroda Hospital, Vadodara and Narhari Hospital, Vadodara in the duration from January to March 2012, under the supervision of Dr. Hiten Kareliya. A questionnaire was prepared in accordance to evaluate risk factors of urinary tract infection. The patients under study were chosen according to specific inclusion criteria. The uropathogens were isolated with the help of biochemical testing. E. coli (38%) was found to be the most prevalent organism followed by Klebsiella and Candida albicans (both 10%), Pseudomonas aeruginosa (9%), Staphylococcus (7%).
QSAR studies on structurally similar oxalyl aryl amino benzoic acid derivatives as antidiabetic agents
Verma N,Mittal M,Verma R K
Calicut Medical Journal , 2008,
Abstract: QSAR (Quantitative structure-activity relationship) analysis based on classical Hansch approach was adopted on recently reported novel series of modified oxalyl aryl amino benzoic acid derivatives as antidiabetic agents. The regression analysis demonstrated that molecular descriptors are important in describing antidiabetic activity of modified oxalyl aryl amino benzoic acid derivatives.Keywords:
Golden Research Thoughts , 2013, DOI: 10.9780/22315063
Abstract: Present study was carried out to delineate toxic level of metal to Lebistesreticulates (guppy) (Poeciliidae).Freshwater fish L. reticulates were subjected to fish bioassay testin the laboratory conditions using chromium (Cr) and lead (Pb) metals. Mortality was assessed at interval of 24 hour (h), 48h, 72h and 96h. Acute toxicity and median lethal concentrations (LC50) were determined by Sprague and Finney method. The 95% confidence interval was calculated as per the literature, Litchfield-Wilcoxon. Slope and regression (R2) were also calculated to confirm the authenticity of the results. LC50 decreased with increased mean exposure times for both metals. Results indicated that the Cr is more toxic than Pb. Pb was found to be least toxic for L. reticulatus. Relationships between 96 h LC50 and physico-chemistry of water showed negative correlation with pH and dissolve oxygen.

Over reporting of RCH services coverage and operational problems in health management information system at the sub-center level
Verma R,Prinja S
Indian Journal of Community Medicine , 2007,
Abstract: Objective: To evaluate the coverage of MCH services as against reported coverage and assess the extent of usage of health information system. Study Design : Community-based cross-sectional study. Setting: Twenty sub-centers of block Lakhanmajra, district Rohtak. Participants: Four hundred mothers having children between 1-2 years age. Statistical Analysis : Simple proportions percentages. Results: The study revealed marked variation in reported and evaluated coverage of various service indicators for MCH care. TT coverage and tubectomies performed were the only notable exceptions that where reported and evaluated coverage matched largely. Distressingly, only 10% of health workers used the eligible couple and child information register for prioritizing clients and preparing the sub-center action plans. The workers did not sufficiently use the information generated through registers, records, and reports maintained at sub-centers.
