Selection of the Capillary Tubes for Retrofitting in Refrigeration Appliances
A.S. Raut,U.S.Wankhede
International Journal of Engineering Science and Technology , 2011,
Abstract: Retrofitting the refrigeration appliances using the capillary tube is reviewed in this paper. If the refrigerant is changed in the existing system, the COP of the system will be affected. It is necessary to do some modifications in the existing system and retrofit it. Changes in compressor design are too complicated and expensive. Hence modification in capillary tube dimensions is preferred so as to compensate for theperformance of the system.

Indian Journal of Medical Microbiology , 2008,
Abstract: Purpose: To evaluate MTT method for detection of drug resistance to rifampicin and isoniazid in M.tuberculosis . This method utilises the ability of viable mycobacterial cells to reduce MTT( 3-4,5-dimethylthiazol-2-yl-2, 5-diphenyl tetrazolium bromide). Methods: The method was standardised with known resistant and sensitive strains of M.tuberculosis and was then extended to 50 clinical isolates. An inoculum of 10 7 cfu/mL was prepared in Middlebrook 7H9 medium supplemented with oleic acid, albumin, dextrose and catalase. For each drug three tubes were used, one with INH(0.2μg/mL) or RIF(1μg/mL), another as inoculum control and third as blank control. These were incubated at 37°C for four and seven days respectively for RIF and INH after which MTT assay was performed. Results were read visually and by colorimeter at 570 nm. Relative optical density unit (RODU) of 0.2 was taken as cut off. Results were compared with drug sensitivity obtained by proportion method using LJ medium. Results: For rifampicin, concordance with proportion method was 90% by visual and 94% by RODU. Sensitivity and specificity was 86.8% and 100% respectively by visual method and 95.2% and 87.5% respectively by RODU. For Isoniazid, concordance was 94% and sensitivity and specificity was 94.7 and 91.7% respectively by both visual and RODU. Conclusions: MTT assay proved to be rapid and cheap method for performing drug sensitivity of M.tuberculosis
Inducible clindamycin resistance in Staphylococcus aureus isolated from clinical samples
Deotale V,Mendiratta D,Raut U,Narang P
Indian Journal of Medical Microbiology , 2010,
Abstract: Purpose: Clindamycin is commonly used in the treatment of erythromycin resistant Staphylococcus aureus causing skin and soft tissue infections. In vitro routine tests for clindamycin susceptibility may fail to detect inducible clindamycin resistance due to erm genes resulting in treatment failure, thus necessitating the need to detect such resistance by a simple D test on routine basis. Materials and Method: 247 Staphylococcus aureus isolates were subjected to routine antibiotic susceptibility testing including oxacillin (1ìg) by Kirby Bauer disc diffusion method. Inducible clindamycin resistance was detected by D test, as per CLSI guidelines on erythromycin resistant isolates. Results: 36 (14.5%) isolates showed inducible clindamycin resistance, nine (3.6%) showed constitutive resistance while remaining 35 (14.1%) showed MS phenotype. Inducible resistance and MS phenotype were found to be higher in MRSA as compared to MSSA (27.6%, 24.3% and 1.6%, 4% respectively). Conclusion: Study showed that D test should be used as a mandatory method in routine disc diffusion testing to detect inducible clindamycin resistance.

Photolysis of pure solid O3 and O2 films at 193 nm
U. Raut,M. J. Loeffler,M. Famá,R. A. Baragiola
Physics , 2010, DOI: 10.1063/1.3589201
Abstract: We studied quantitatively the photochemistry of solid O3 and O2 films at 193 nm and 22 K with infrared spectroscopy and microgravimetry. Photolysis of pure ozone destroyed O3, but a small amount of ozone remained in the film at high fluence. Photolysis of pure O2 produced O3 in an amount that increased with photon fluence to a stationary level. For both O2 and O3 films, the O3:O2 ratio at saturation is 0.03, nearly 10-30 times larger than those obtained in gas phase photolysis. This enhancement is attributed to the increased photodissociation of O2 due to photoabsorption by O2 dimers, a process significant at solid state densities. We obtain initial quantum yield for ozone synthesis from solid oxygen, {\Phi} (O3) = 0.18 and for destruction of ozone and oxygen in their parent solids, {\Phi} (- O3) = 1.7 and {\Phi} (-O2) = 0.28. Combined with known photoabsorption cross sections, we estimate probabilities for germinate recombination of 0.15 for O3 fragments and 0.90 for oxygen atoms from O2 dissociation. Using a two-parameter kinetic model, we deduce the average probabilities for the reaction of an O atom with O2 and O3 to be 0.10 and 1, respectively. These probabilities are the same for both O2 and O3 films, even though the distribution of kinetic and internal energy of the photofragments is very different in both cases. This finding suggests efficient energy relaxation of photofragments in the solid occur prior to their reactions with other species.

Nepalese Journal of Ophthalmology , 2012, DOI: 10.3126/nepjoph.v4i1.5874
Abstract: Background: Ichthyosis is an infrequent clinical entity worldwide (1:300,000 births). When diagnosed in a newborn, two forms can be identified: collodion baby and its most severe form, harlequin fetus or maligna keratoma. In both cases, clinical manifestations are thick and hard skin with deep splits. The splits are more prominent in the flexion areas. Case: We report a case of a 4- day-old baby who was referred to JNMC Eye OPD by the Pediatric Department of the JNMC. He was having severe bilateral ectropion of the upper lids and chemosis of conjuntiva, without corneal involvement. There was distortion of the pinna and peeling of the skin, more over the chest around the neck region and over the flexor aspect of limbs. Conclusion: Management of collodion baby requires a multi-disciplinary approach. DOI: http://dx.doi.org/10.3126/nepjoph.v4i1.5874 NEPJOPH 2012; 4(1): 184-186

Abstract: The ethnomedicinal practices appear to be a part of traditional system of treatment for domestic cattle in remote areas of Nepal. The knowledge of local healers with the utilization of biological resources in various ailments is still survived and is communicated verbally to limited family members. As a result, this knowledge is at threatened stage. Now days, documentation of traditional knowledge is receiving much attention. The study carried out in seven village development committees of Morang district concerns with the traditional uses of crude drugs obtained form 37 plant species belonging to 24 families which are used for the treatment of 21 common ailments of domestic cattle. Participatory Rural Appraisal (PRA) method was applied to collect the data. The information on the correct botanical sources, family, local name, plant part used, method of preparation and method of application of different crude drugs were investigated in this study.

Communications of the IBIMA , 2009,
Abstract: The industry landscape in telecommunications is changing rapidly at the moment. Services are increasingly shifting from voice to data and from circuit-switched to packet-switched ones. LTE and WiMAX are the two technologies poised to dominate next generation mobile networks. Battle between LTE & WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards through IEEE 802.16 and is up and running but lacks in substantial roll out plans due to cost. On the contrary, LTE upgrades from 3G networks are rumored to be as simple as slotting in a new card in the rack. Researchers and business community is divided over the choice of LTE and WiMAX. Few researchers feel that 3G LTE can bring substantial technologies and economical benefits to operators deploying mobile networks beyond 3G. This paper presents a comprehensive comparative study to help arrive at the choice between LTE and WiMAX.

Communications of the IBIMA , 2008,
Abstract: Software development is a highly creative and collaborative endeavor in which success requires a fine degree of coordination between many people from many different disciplines, often working across different geographies and time zones and sometimes across cultural borders. When implementing software development in a global environment, a popular strategy is the establishment of globally distributed teams.Project management owes its existence as a management discipline to the complex, high technology undertakings. Projects are complex endeavors and project outcomes are far from being certain. Software development teams are plagued by management problems that result in missed deadlines, budget overruns, and canceled projects, and effective management remains an open problem. The management aspect becomes further challenging and complicated while dealing ethical, time zone, cross cultural issues inherent to a globally distributed team. In this paper we have presented an adept management framework for globally distributed teams.

Abstract: Since plants are used as therapeutic agents, the present study was conducted to evaluate the phytochemical profile and antibacterial activities of extracts of. Eclipta alba and Tylophora indica .Studies on the antibacterial activity of methanol, petroleum ether and aqueous extracts of dry leaf, stem and root of Eclipta alba and Tylophora indica was evaluated using zone of inhibition studies and minimum inhibitory concentration. The microorganisms used include Escherichia coli, Micrococcus roseus and Pseudomonas flavescens . The extract exhibited antibacterial activity against these experimental strains. Methanol extracts shows higher degree of antibacterial activity than aqueous and petroleum ether extracts. The minimum inhibitory concentration ranged between 12.5mg/mL and 75mg/mL depending on microorganism and various extract. Screening of the phytochemical extracts revealed the presence of compounds like alkaloids, glycosides, tannins and flavonoids. Escherichia coli and Pseudomonas flavescens are more sensitive where as Micrococcus roseus is less sensitive to extracts of Eclipta alba and Tylophora indica. The experimental observation shows that Eclipta alba and Tylophora indica have antibacterial activity and can be used for therapeutic purposes.
