On bounds of certain classes of special functions
C. M. Joshi,Sadhana Nalwaya
Tamkang Journal of Mathematics , 2001, DOI: 10.5556/j.tkjm.32.2001.15-20
Abstract: Inequalities of the ratios of Whittaker function, which include in its fold inequalities of a large class of special functions, are obtained. In the sequel inequalities of the ratios of Bessel functions of 2nd kind and inequalities of the ratios $ J_v(x) / Y_v(x) $ are also derived. Finally, we point out some correction which appear in the paper of Joshi and Bissu (J. Aust. Math. Soc., Ser. A. 50(1991), 333-342).

Abstract: Macrophytes play an important role in nutrient dynamics of the lake ecosystem. The aim of this study is to determine the growth pattern and to evaluate the nutrient accumulation capacity of water hyacinth [Eichhornia crassipes (Mart) Solms] growing in Robrtson Lake, Jabalpur. The paper is outcome of in situ experiment conducted in Robertson lake (which has a dense mat of water hyacinth), as well as laboratory microcosms experiment. Water hyacinth grew at an average rate of 3.85 g dw m-2d and it accumulates 263 kg N ha-1 yr-1 and 67 kg P ha-1 yr-1, respectively. The chemistry of lake water does not show any significant seasonal variation; however the growth of water hyacinth in laboratory microcosms removed 79% of PO4-P and 58% NO3-N from the growth medium. Thus, the data reveal that water hyacinth stands growing in the lake highly buffered the water chemistry by reducing nutrient level, in spite of heavy nutrient load in the lake from domestic waste and factory effluent.
Generalized Predictive Control and Neural Generalized Predictive Control
Sadhana CHIDRAWAR,Balasaheb PATRE
Leonardo Journal of Sciences , 2008,
Abstract: As Model Predictive Control (MPC) relies on the predictive Control using a multilayer feed forward network as the plants linear model is presented. In using Newton-Raphson as the optimization algorithm, the number of iterations needed for convergence is significantly reduced from other techniques. This paper presents a detailed derivation of the Generalized Predictive Control and Neural Generalized Predictive Control with Newton-Raphson as minimization algorithm. Taking three separate systems, performances of the system has been tested. Simulation results show the effect of neural network on Generalized Predictive Control. The performance comparison of this three system configurations has been given in terms of ISE and IAE.

Assay of tegaserod maleate by difference spectroscopy
Rajput Sadhana,Raj Hasumati
Indian Journal of Pharmaceutical Sciences , 2007,
Abstract: A simple analytical method for the estimation of tegaserod maleate has been developed to analyze the drug in bulk and in tablet formulation. The method is based on difference spectroscopy and is quite simple, rapid, inexpensive and sensitive. The Beer′s law range was followed in the concentration range of 1-30 μg/ml of tegaserod maleate. The molar absorptivity was 1.7920x10 4 l/mole/ cm. The method does not require any separation of soluble excipients as they do not interfere in the estimation.
A ten year study of STD Cases in an urban clinic in Calcutta
Ghosh Sadhana,Roy Alok
Indian Journal of Dermatology, Venereology and Leprology , 1994,
Abstract: Total 16440 patients attended the STD clinic during the 10 years period of study from 1984 to 1993. From 1988 number of STD caes were gradually decreasing probably due to less promiscuity in fear of AIDS and different measures taken to prevent transmission of HIV infection. But it does not lessen the importance of STD control, because syphilis is still prevalent (8%) with congenital syphilis. Peak in the incidence of chancroid (15%) is alarming as this may lead to increased transmission of HIV infection in near future. Male unmarried constituted the bulk of STD sufferers (44%) and married males (34%), while female unmarried and married patients were 1% and 20% respectively, 5.7% of antenatal mothers were strongly seroreactive for syphilis. Therefore all antenatal mothers should be screened for STD and routine serological test for syphilis should be done.
K* production in Cu+Cu and Au+Au collisions at sqrt(s_{NN}) = 62.4 GeV and 200 GeV in STAR
Sadhana Dash,for the STAR Collaboration
Physics , 2008, DOI: 10.1088/0954-3899/35/10/104057
Abstract: We report the measurements of $p_T$ spectra of $K^*$ up to intermediate $p_T$ region in mid-rapidity through its hadronic decay channel using the STAR detector in Au+Au and Cu+Cu collisions at $\sqrt{s_{\mathrm{NN}}}$= 62.4 GeV and 200 GeV. Particle ratios such as $K^{*}/K$ and $K^{*}/\phi$ is used to understand the rescattering and regeneration effect on $K^{*}$ production in the hadronic medium. The $K^*$ $v_{2}$ measurement using a high statistics Au+Au 200 GeV dataset and nuclear modification factor measurement supports the quark coalescence model of particle production in the intermediate $p_T$ range.
K* production in Heavy Ion Collisions at RHIC
Sadhana Dash,for the STAR Collaboration
Physics , 2007, DOI: 10.1088/0954-3899/35/4/044061
Abstract: Study of resonances with their short life-times provides useful tools to probe the properties of hot and dense matter produced in relativistic heavy ion collisions. The high density and/or high temperature of the medium can modify resonance properties such as mass and width. Therefore, measurement of these properties can reveal important information about the evolution dynamics in heavy ion collisions. We report the measurements of $K^{*}$ transverse momentum($p_T$) spectra at mid-rapidity via its hadronic decay channel up to intermediate $p_{T}$ of 2.9 GeV/c using the STAR detector in Au+Au and Cu+Cu collisions at $\sqrt{s_{\mathrm{NN}}}$= 62.4 GeV and 200 GeV. These results are compared to previously reported $K^{*}$ results from Au+Au collisions at RHIC. Integrated yield ratios of $K^{*}/K$ and $K^{*}/\phi$ are used to understand the rescattering and regeneration effects on $K^{*}$ production.
Diuretic activity of a herbal product UNEX
Nalwaya Narendra,Jarald E,Asghar Suhail,Ahmad Showkat
International Journal of Green Pharmacy , 2009,
Abstract: In the present study, product UNEX capsules (syn. Herbajules Tricare in Malaysia) was tested for diuretic activity using the Lipschitz test. The product UNEX containing the extracts of Boerhaavia diffusa and Tribulus terrestris was studied at two dose levels of 600 and 800 mg/kg body weight (p.o.). Standard drug used was furosemide (20 mg/kg body weight) in a 0.9% sodium chloride solution. Urine volume was recorded for all the groups for 5 hours. The product UNEX exhibited significant diuretic activity at doses of 600 and 800 mg/kg body weight as evidenced by increased total urine volume and the urine concentration of Na + , K + , and Cl . The result thus supports the use of product UNEX as diuretic.

V. N. Bhusari, Rashmi Dahake, Sadhana Rayalu, Amit Bansiwal
Advances in Nanoparticles (ANP) , 2016, DOI: 10.4236/anp.2016.51008
Abstract: Hexavalent chromium is one of the important heavy metals found in water and wastewater. The hexavalent form of chromium is considered to be a human carcinogen because of its mutagenic and carcinogenic properties. This work has focused on the comparison of copper oxide nanoparticles and aluminium oxide nanoparticles for the removal of chromium(VI) from water. The cooper oxide nanoparticles (CuNP) and aluminium oxide nanoparticles (AlNP) were synthesised by sol gel method. Both the adsorbents were evaluated for the adsorption capacity using Langmuir and Freundlich adsorption model. The CuNP and AlNP were characterized for X-ray diffraction and SEM. The study indicated that the AlNP showed better removal as compared to CuNP and can be further explored as potential adsorbent for hexavalent chromium removal.
