A Novel Resource Distributed Discovery and Management in Grid Computing
M. Brinda Kumar,Dr. K.P. Kaliyamurthie
International Journal of Computer Science and Mobile Computing , 2013,
Abstract: In grid-computing environment the computer resources are shared under the grid nodes.Resource discovery is an important process for finding suitable nodes that satisfy application requirements ingrid environment. In most of the existing resource discovery mechanisms rely mainly on recent observedresource capacities of individual nodes to make their deployment decision based on current status of thenodes have severe limitations to achieve scalability because of the presence of internodes dynamism inaddition to the internodes heterogeneity. Individual nodes have widely varying resource capabilities due tovarying loads, network connectivity, churn, or user behavior. Besides internodes heterogeneity, many of thesesystems also show a high degree of internodes dynamism, so that selecting nodes based only on their recentlyobserved resource capacities can lead to poor deployment decisions resulting in application failures ormigration overheads.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0097993
Abstract: Background Private Practitioners (PP) are the primary source of health care for patients in India. Limited representative information is available on TB management practices of Indian PP or on the efficacy of India’s Revised National Tuberculosis Control Programme (RNTCP) to improve the quality of TB management through training of PP. Methods We conducted a cross-sectional survey of a systematic random sample of PP in one urban area in Western India (Pune, Maharashtra). We presented sample clinical vignettes and determined the proportions of PPs who reported practices consistent with International Standards of TB Care (ISTC). We examined the association between RNTCP training and adherence to ISTC by calculating odds ratios and 95% confidence intervals. Results Of 3,391 PP practicing allopathic medicine, 249 were interviewed. Of these, 55% had been exposed to RNTCP. For new pulmonary TB patients, 63% (158/249) of provider responses were consistent with ISTC diagnostic practices, and 34% (84/249) of responses were consistent with ISTC treatment practices. However, 48% (120/249) PP also reported use of serological tests for TB diagnosis. In the new TB case vignette, 38% (94/249) PP reported use of at least one second line anti-TB drug in the treatment regimen. RNTCP training was not associated with diagnostic or treatment practices. Conclusion In Pune, India, despite a decade of training activities by the RNTCP, high proportions of providers resorted to TB serology for diagnosis and second-line anti-TB drug use in new TB patients. Efforts to achieve universal access to quality TB management must account for the low quality of care by PP and the lack of demonstrated effect of current training efforts.
Cross-sectional imaging work-up of adrenal masses
Brinda Rao Korivi,Khaled M Elsayes
World Journal of Radiology , 2013, DOI: 10.4329/wjr.v5.i3.88
Abstract: Advances in medical imaging with current cross-section modalities enable non-invasive characterization of adrenal lesions. Computed tomography (CT) provides characterization with its non-contrast and wash-out features. Magnetic resonance imaging (MRI) is helpful in further characterization using chemical shift imaging (CSI) and MR spectroscopy. For differentiating between benign and malignant masses, positron emission tomography (PET) imaging is useful with its qualitative analysis, as well as its ability to detect the presence of extra-adrenal metastases in cancer patients. The work-up for an indeterminate adrenal mass includes evaluation with a non-contrast CT. If a lesion is less than 10 Hounsfield Units on a non-contrast CT, it is a benign lipid-rich adenoma and no further work-up is required. For the indeterminate adrenal masses, a lipid-poor adenoma can be differentiated from a metastasis utilizing CT wash-out features. Also, MRI is beneficial with CSI and MR spectroscopy. If a mass remains indeterminate, PET imaging may be of use, in which benign lesions demonstrate low or no fluorodeoxyglucose activity. In the few cases in which adrenal lesions remain indeterminate, surgical sampling such as percutaneous biopsy can be performed.

Abstract: Background: It has been more than 1 year since the last case of wild polio virus occurred in the country and we are at the final phase of polio eradication. It needs to enhance/ sustain all activities of polio eradication. This study was carried out to critically evaluate the various activities undertaken and make the suggestions for improvement during the National Immunization Day (NID) of February 2012 under Intensified Pulse Polio Immunization Program (IPPI) in urban/ rural areas of Ahmedabad, Kheda and Gandhinagar districts of Central Gujarat. Methodology: External evaluators after a training cum orientation program undertook the evaluation of NID (Feb 2012) in 3 districts of Central Gujarat in identified 20 booths through assessing booth based vaccination and undertaking surveys of house to house activities and at migratory/ transit/ street sites. Results: (a) Booth based activities: Most booths were accessible and had supply of logistics (IEC materials, stationeries, vaccines, cold chain equipments, marker pens). Understaffing and last minute replacement with untrained staff and non participation of community or nongovernmental organizations (NGOs) were some of the issues. (b) House to house visits: External monitors could detect 7 missed sites with 63 unvaccinated children while the in house health supervisors could not detect any site. False P detection rates were also high for external monitors (5.3%) than in house supervisors (1.3%). (c) Migratory sites: Visit to 118 migratory sites yielded even more children as not vaccinated (16.8%). 21 transit sites showed the inadequacies of program where almost one third of children could not be checked for the vaccination. (d) Street surveys: Street surveys done after completion of NID (Based on finger markings alone) found 12.7% children as not vaccinated. Conclusions: Present communication aims to explore the problematic issues in achieving vaccination coverage, capacity building of team members and operational/ logistic aspects and provide intensive qualitative inputs.
Oligomeric protein structure networks: insights into protein-protein interactions
KV Brinda, Saraswathi Vishveshwara
BMC Bioinformatics , 2005, DOI: 10.1186/1471-2105-6-296
Abstract: A variety of interactions such as hydrogen bond, salt bridges, aromatic and hydrophobic interactions, which occur at the interfaces are identified in a consolidated manner as amino acid clusters at the interface, from this study. Moreover, the characterization of the highly connected hub-forming residues at the interfaces and their comparison with the hubs from the non-interface regions and the non-hubs in the interface regions show that there is a predominance of charged interactions at the interfaces. Further, strong and weak interfaces are identified on the basis of the interaction strength between amino acid residues and the sizes of the interface clusters, which also show that many protein interfaces are stronger than their monomeric protein cores. The interface strengths evaluated based on the interface clusters and hubs also correlate well with experimentally determined dissociation constants for known complexes. Finally, the interface hubs identified using the present method correlate very well with experimentally determined hotspots in the interfaces of protein complexes obtained from the Alanine Scanning Energetics database (ASEdb). A few predictions of interface hot spots have also been made based on the results obtained from this analysis, which await experimental verification.The construction and analysis of oligomeric protein structure networks and their comparison with monomeric protein structure networks provide insights into protein association. Further, the interface hubs identified using the present method can be effective targets for interface de-stabilizing mutations. We believe this analysis will significantly enhance our knowledge of the principles behind protein association and also aid in protein design.It is well known that a vast majority of cellular functions are mediated through protein-protein and protein-DNA interactions. Protein association is implicated in cellular signal transduction, antigen-antibody binding, in the regulation of g

Abstract: The essay as an article seeks to explore the complexities and the dilemma of the immigrants in Exile literature by focusing upon its attraction, repulsion and their exploitation by the vested interests. The study shows how Indian diasporic literature novelists like Anita Desai has chartered this very crisis tormenting the sensitive soul of immigrants. The essay also attempts to highlight, through an authentic study of the novel Bye-Bye Blackbird, how Desai has delineated the problems and plights of exile and the diasporic individuals caught in the crisis of a changing society. Through Desai’s innovative approach compelling drama and masterful style the essay tries to capture the confusions and conflicts of the exiles and shows how her novel Bye-Bye Blackbird simultaneously pictures a holistic view of the Exile literature and the Indian Diasporic literature. The purpose of this paper is to serve as an introduction and inducement to the study of Exile literature. This paper proposes to present a broad outline to Anita Desai’s novel Bye- Bye Blackbird.

International Journal of VLSI Design & Communication Systems , 2012,
Abstract: In this paper fringe capacitance of double hetero gate Tunnel FET has been studied. The physical modelfor fringe capacitance is derived considering source gate overlap and gate drain non overlap. Inerface trap charge and oxide charges are also introduced under positive bias stress and hot carrier stress and their effect on fringe capacitance is also studied. The fringe capacitance is significant speed limiter in Double gate technology. The model is tested by comparing with simulation results obtained from Sentauras TCADsimulations.
Politics of Hunger and Development: A Sociological Review of India’s Developmental Discourse  [PDF]
M. Ashok Kumar
Sociology Mind (SM) , 2012, DOI: 10.4236/sm.2012.24050
Abstract: This paper attempts to address the problem of hunger from the viewpoint of its social face against the backdrop of fast growing economy of India. Current sad state of affairs in the domain of poverty and hunger are nothing but the cumulative result of what happens in the Indian development planning since Independence, or at least in the name of development planning. This paper sociologically examines three most critical events in the history of Indian development planning, which are introduced to mitigate hunger and poverty, in both urban and rural India. The central focus of this paper is to highlight politics of those development initiatives and liquidation of public planning at the level of implementation, which eventually increased the gap between rich and poor, and left the Indian poor to their own fate. This paper also examines the most significant aspect of delinking power relations from the development discourse of India by providing more room for populist ideas with an aim to gain political mileage by the ruling elite. The present state of affairs with respect to poverty and hunger coupled with low standards of health, literacy and social awareness in India call for serious introspection. This paper, therefore, critically looks at Indian development discourse from the perspective of power relations, both established and emerging, which could alter our views on India and its growth story.
