Evaluation of heat loss coefficients in solar flat plate collectors
Y. Rajasekhar,K. V. Sharma,M. Basaveswara Rao
Journal of Engineering and Applied Sciences , 2009,
Abstract: Flat Plate Collectors (FPC) is widely used for domestic hot-water, space heating/drying, for applications requiring temperatures less than 100oC. The absorber plate of the FPC transfers solar energy to liquid flowing inside the tubes. The flow takes place by thermosyphon effect or by forcing water through the tubes. However, some of the energy absorbed by the plate is lost to the atmosphere as temperature of the plate is higher than the ambient temperature. The efficiency of FPC is dependent on the temperature of the plate which in turn is dependent on the nature of flow of fluid inside the tube, the emissivity of the plate and glass cover, wind loss coefficient, inclination of the FPC with respect to horizontal. The objective of the present work was to evaluate theoretically and experimentally the heat loss coefficient from flat plate collector. An experimental system was designed and fabricated to conduct experiments at different heat flux conditions. The effect of other significant parameters was evaluated by conducting the experiment.
Ichthyosiform sarcoidosis following chemotherapy of Hodgkin's disease
Sawhney M,Sharma Y,Gera V,Jetley S
Indian Journal of Dermatology, Venereology and Leprology , 2003,
Abstract: Acquired ichthyosis in adults may reflect internal disease, viz. internal malignancy, especially Hodgkin's lymphoma or sarcoidosis. We report a patient who developed ichthyosiform sarcoidosis over a year after completion of 6 cycles of combination chemotherapy for Hodgkin's disease. To our knowledge, the development of ichthyosiform sarcoidosis after chemotherapy for Hodgkin's disease has not been described earlier.

Antimicrobial evaluation of mangiferin analogues
Singh S,Kumar Y,Kumar S,Sharma V
Indian Journal of Pharmaceutical Sciences , 2009,
Abstract: The naturally occurring xanthone glycoside mangiferin has been isolated by column chromatography from the ethanol extract of stem bark of Mangifera indica. Mangiferin was further converted to 5-(N-phenylaminomethyleno)mangiferin, 5-(N-p-chlorophenylaminomethyleno) mangiferin, 5-(N-2-methylphenylaminomethyleno) mangiferin, 5-(N-p-methoxyphenylaminomethyleno) mangiferin, 5-(N,N-diphenylaminomethyleno) mangiferin, 5-(N--napthylaminomethyleno) mangiferin and 5-(N-4-methylphenylaminomethyleno) mangiferin. Mangiferin and its analogues were characterized by melting point and R f value determination and through spectral technique like UV, IR, and NMR spectral analysis. The synthesized compounds were screened for antimicrobial activity.

Case study: Systemic complications following absolute alcohol embolisation of scalp arteriovenous malformation
S Agrawal, Y.S Payal, S Burathoki, V Asthana, J.P Sharma
Southern African Journal of Anaesthesia and Analgesia , 2010,
Abstract: Alcohol ablation is an accepted technique for the management of arteriovenous malformations. It is preferred due to the unique property of absolute alcohol to cause complete ablation and prevention of revascularisation. However, this technique is associated with multiple complications which may lead to patient morbidity. Here the case is presented of a female patient with scalp arteriovenous malformation who underwent alcohol ablation and developed supraventricular arrhythmia accompanied with haemodynamic instability and intravascular haemolysis in the postoperative period.

Pravara Medical Review , 2009,
Abstract: Pulmonary Tuberculosis is most common form of tuberculosis (TB). The present study was conducted to study the TB cases attending DMC cum DOTS centre at PRH, Loni. It is a retrospective record based study. TB patients information was collected from the record registers at DOTS centre. Out of 611 patients diagnosed, 188 (30%) are from the age group 0- 10 years. Extrapulmonary TB patients were more 222(36%). New smear positive TB cases were 196 (32%). Total 61% patients were categorized in CAT- I, 9% in CAT-II & 30% in CAT III. Treatment completion rate was 93.69%. In view of the high success of DOTS strategy, the same is recommended to be continued. For transferred cases, a better system of follow up may be explored for monitoring all these cases.
Magnetic-field-induced collapse of charge-ordered nanoclusters and the Colossal Magnetoresistance effect in Nd(0.3)Sr(0.3)MnO(3)
T. Y. Koo,V. Kiryukhin,P. A. Sharma,J. P. Hill,S-W. Cheong
Physics , 2001, DOI: 10.1103/PhysRevB.64.220405
Abstract: We report synchrotron x-ray scattering studies of charge/orbitally ordered (COO) nanoclusters in Nd$_{0.7}$Sr$_{0.3}$MnO$_3$. We find that the COO nanoclusters are strongly suppressed in an applied magnetic field, and that their decreasing concentration follows the field-induced decrease of the sample electrical resistivity. The COO nanoclusters, however, do not completely disappear in the conducting state, suggesting that this state is inhomogeneous and contains an admixture of an insulating phase. Similar results were also obtained for the zero-field insulator-metal transition that occurs as temperature is reduced. These observations suggest that these correlated lattice distortions play a key role in the Colossal Magnetoresistance effect in this prototypical manganite.
Magneto-Seebeck effect in spin-valve with in-plane thermal gradient
S. Jain,D. D. Lam,A. Bose,H. Sharma,V. R. Palkar,C. V. Tomy,Y. Suzuki,A. A. Tulapurkar
Physics , 2014,
Abstract: We present measurements of magneto-Seebeck effect on a spin valve with in-plane thermal gradient. We measured open circuit voltage and short circuit current by applying a temperature gradient across a spin valve stack, where one of the ferromagnetic layers is pinned. We found a clear hysteresis in these two quantities as a function of magnetic field. From these measurements, the magneto-Seebeck effect was found to be 0.82%.

Abstract: The change control is ―A process that ensures that changes to materials; methods, equipment and software are properly documented, validated, approved and traceable‖. The process requires eight basic steps: Identification, documentation review, change proposal, change classification, implementation plan, installation, verification, closure. Changes are outlines as Major, Moderate & Minor. A compliance of regulatory group within the company determines the filing impact and submits it to FDA,-A prior- Approval supplement (PAS) for major changes, A CBE -30 or CBE-0 for moderate changes or Annual report for Minor changes. Firms are expected to write adequate Standard Operating Procedure (SOP) for the change control & be in total compliance with proper documentation. Considering the regulatory prospective of change control procedures, it is important to note that there are many guideline which describe the control of changes in manufacturing few references includes 21 CFR Part211: Sec. 211.100, 21 CFR Part 211.194 (Laboratory Records), ICH Q7A and USFDA Guidance for Industry: Change to an approved NDA or ANDA (April 2004- Revison-1).
