National Journal of Community Medicine , 2012,
Abstract: Background: The complaint of vaginal discharge is very common, particularly in south East Asia it is associated with considerable disability, health seeking, and associated costs. Objective: To estimate the hospital based prevalence of vaginal discharge, to find out socio-demographic variables associated with the complaint of vaginal discharge, perceived causes of vaginal discharge and association of vaginal discharge with other gynaecological problems among the women of reproductive age. Methods: The present cross sectional study was conducted in one of the tertiary care hospital of Bareilly district. The respondent were the female in reproductive age group (15-49yrs) attending Obst. & gynae OPD. Sample size of 590 was calculated, for sample to be more representative of population, a total of 1100 female in reproductive age group were included in the study. . Odds ratio (OR) and their 95% confidence interval (CI) were calculated to estimate the strength of association between vaginal discharge and other gynaecological symptoms. Chi square test was applied as test of significance for data analysis. Results: Prevalence of vaginal discharge was found to be 24.6%. Factors like increasing age, married (26.2%), illiteracy (60.1%), Muslim religion (28.7%), low socioeconomic status, high parity, history of induced abortion and place of delivery were found to be significantly associated with vaginal discharge. Internal gynaecological problem was perceived as a main cause for vaginal discharge (73.3%). Vaginal discharge was found to be significantly associated with other gynaecological problems. Recommendation: There is need for creating community awareness about health care facilities and instills self concern in women for their own health needs.

Indian Journal of Anaesthesia , 2010,
Abstract: The need for early ambulation for caring of the neonate by mothers makes postoperative pain management after cesarean delivery unique. Favorable results have been observed with buprenorphine, clonidine and bupivacaine as epidural analgesics. This prospective, randomised triple blind control study was carried out among 112 lower segment caesarean segment (LSCS) patients, divided into three groups, to assess the analgesic efficacy and side effects of epidural analgesia, with an intermittent top up of (i) bupivacaine (0.125%) and buprenorphine (0.075 mg) (ii) bupivacaine (0.125%) and clonidine (37.5 microgram) and (iii) bupivacaine (0.125%) alone, in LSCS cases. The demographic characteristics (age, weight and height) of the three groups were comparable and the differences were not statistically significant. The mean duration of the analgesia was significantly longer in the group one patients receiving buprenorphine plus bupivacaine (690 ± 35 minutes) and it was lowest in group three patients receiving bupivacaine (170 ± 31 minutes) alone. The mean highest pain score (VAS scale) was significantly lower (3.4 ± 0.6) in group one patients and it was highest in group three (6.7 ± 0.8) patients. Requirement of continuation of epidural analgesia after 15 hours of operation and requirement of diclonfenac injections as well as incidence of itching and pruritus was significantly lower in group one patients. Incidence of nausea and vomiting was the lowest in group one patients. Incidence of respiratory depression, sedation and hypotension were nil in all three group of patients. Epidural buprenorphine combined with bupivacaine produced significantly longer duration and better quality of analgesia than bupivacaine combined with clonidine or bupivacaine alone, and it was safe in LSCS patients, for post-operative analgesia.

Gaurav K. Agrawal, Daniel Berg
Journal of Service Science and Management (JSSM) , 2009, DOI: 10.4236/jssm.2009.24052
Abstract: The service sector is receiving much deserved attention resulting from its inevitable role in a country’s economic de-velopment. Despite all the efforts gaps such as the relationship between technological advances and service development are yet to be revealed from the perspective of new applications that organizations want to develop and implement. This paper explores opportunities using a comprehensive model (and CRM, as an example) that can be used to extend the research relating service development to the technology development aspects of the market.
First and Second Order Statistics Features for Classification of Magnetic Resonance Brain Images  [PDF]
Namita Aggarwal, R. K. Agrawal
Journal of Signal and Information Processing (JSIP) , 2012, DOI: 10.4236/jsip.2012.32019
Abstract: In literature, features based on First and Second Order Statistics that characterizes textures are used for classification of images. Features based on statistics of texture provide far less number of relevant and distinguishable features in comparison to existing methods based on wavelet transformation. In this paper, we investigated performance of texture-based features in comparison to wavelet-based features with commonly used classifiers for the classification of Alzheimer’s disease based on T2-weighted MRI brain image. The performance is evaluated in terms of sensitivity, specificity, accuracy, training and testing time. Experiments are performed on publicly available medical brain images. Experimental results show that the performance with First and Second Order Statistics based features is significantly better in comparison to existing methods based on wavelet transformation in terms of all performance measures for all classifiers.

Abstract: Groundwater is an important source of water for domestic, agricultural, and industrial requirements for Gurgaon district, which is economic capital of Haryana state, stands at very critical juncture due to its alarming decrease in ground water levels. As surface water potential is not promising in the district, there is increased dependence on ground water for meeting almost all types of water requirements. Gurgaon district is located between 76040"E to 77015" E longitude and 28010" N to 28032" N latitude and have geographical area of 1254.62 Km2 with an average elevation of 220 meters for its four blocks viz. Gurgaon, Sohna, Farukhnagar and Pataudi. The share of rural population is 64.42% of the total population and agriculture is the predominant occupation of the majority of the people in Gurgaon district. The main source of the irrigation is tube-well, which irrigates about 96.8% of the total irrigated area. Indiscriminate use of underground water for agricultural and other uses has depleted the ground water to the level of over exploited category. In this paper effort has been made to see the application of “processing MODFLOW for Windows (PMWIN)” for sustainable ground water resources study for Gurgaondistrict, Haryana, India.

SAR signal processing algorithms

Journal of Engineering and Applied Sciences , 2009,
Abstract: In space borne SAR systems some form of data compression is required to reduce the bandwidth of the downlink channel. In the present paper we have represented the complex SAR raw data with amplitude-phase (AP) and then applied the devised algorithm. It is observed that the phase information of the compressed data is preserved to the great extent. The quality of the reconstructed data is compared in terms of the important performance evaluation parameters like signal to noise ratio (SNR), standard deviation of the phase (PSD), mean phase error (MPE) and the compression ratio (CR). The amplitude-phase algorithm is compared with that of Block Adaptive Quantization (BAQ) algorithm. The evaluation procedure is carried out in two domains, raw data domain and image domain. Numerical experiments were carried out using ERS-2 satellite data supplied by European Space Agency (ESA) showing that amplitude-phase algorithm provides us with more Compression Ratio (CR) choices than BAQ and for certain CR, AP algorithm provides at least one choice whose performance is better than or equal to that of BAQ. These two algorithms neither affect spatial resolution nor generate geometric distortion. Both of them have only a little effect on radiometric resolution.

The paper concludes with some suggestive measures in combating the Role of Electricity (energy) in the economic development of the state in particular and country as a whole
Asymmetric nuclear matter and neutron-skin in extended relativistic mean field model
B. K. Agrawal
Physics , 2010, DOI: 10.1103/PhysRevC.81.034323
Abstract: The density dependence of the symmetry energy, instrumental in understanding the behaviour of the asymmetric nuclear matter, is investigated within the extended relativistic mean field (ERMF) model which includes the contributions from the self and mixed interaction terms for the scalar-isoscalar ($\sigma$), vector-isoscalar ($\omega$) and vector-isovector ($\rho$) mesons upto the quartic order. Each of the 26 different parameterizations of the ERMF model employed are compatible with the bulk properties of the finite nuclei. The behaviour of the symmetry energy for several parameter sets are found to be consistent with the empirical constraints on them as extracted from the analyses of the isospin diffusion data. The neutron-skin thickness in the $^{208}$Pb nucleus for these parameter sets of the ERMF model lie in the range of $\sim 0.20 - 0.24$ fm which is in harmony with the ones predicted by the Skyrme Hartree-Fock model. We also investigate the role of various mixed interaction terms which are crucial for the density dependence of the symmetry energy.
