Topological optimization and fatigue life prediction of a single pad externally adjustable fluid film bearing.

This work focuses on the prediction and comparison of the fatigue life of topologically optimized pads in an externally adjustable fluid film (EAFF) bearing. It integrates one-way/two-way fluid-structure interaction analysis, topological optimization (TO), and design modifications of the pad of an externally adjustable fluid film bearing. The major goal is to create an optimum pad design that minimizes weight and maintains structural integrity, and then to predict and compare the fatigue life of these alternative designs.

Conservative Surgical Management of a Pulmonary Hydatid Cyst in an Adolescent Having Extra-pulmonary Lesions by a Multi-disciplinary Approach.

causes hydatid cysts, a significant zoonotic and pulmonary parasitic disease that can mimic various pathologies and is often harder to manage than the disease itself. A hydatid cyst is considered a significant health problem in India, Iran, China, and Mediterranean countries, which lack satisfactory environmental health, preventive medicine, and veterinarian services. Echinococcosis continues to be a major community health burden in several countries, and in some terrains, it constitutes an emerging and re-emerging disease.

Compositional Dependence of Solubility/Retention of Molybdenum Oxides in Aluminoborosilicate-Based Model Nuclear Waste Glasses.

Molybdenum oxides are an integral component of the high-level waste streams being generated from the nuclear reactors in several countries. Although borosilicate glass has been chosen as the baseline waste form by most of the countries to immobilize these waste streams, molybdate oxyanions (MoO) exhibit very low solubility (∼1 mol %) in these glass matrices. In the past three to four decades, several studies describing the compositional and structural dependence of molybdate anions in borosilicate and aluminoborosilicate glasses have been reported in the literature, providing a basis for our understanding of fundamental science that governs the solubility and retention of these species in the nuclear waste glasses.

Human immunodeficiency viruses types 1 and 2 infection among replacement blood donors in Mumbai (Bombay).

Between 1993-96, blood donated by 12,235 replacement blood donors was screened by various Enzyme Linked Immunosorbent Assays for detecting antibodies to Human Immunodeficiency Viruses types 1 and 2 according to the guidelines specified by Indian--Food and Drug Administration. 222 replacement blood donors (1.81%) were found to be seropositive for antibodies to Human Immunodeficiency Virus types 1 and 2.

Increasing prevalence of HIV-2 and dual HIV-1-2 infections among patients attending various outdoor patient departments in Mumbai (Bombay).

Between 1993-96, a serological study was carried out for differentially identifying HIV-1 and HIV-2 infections among the high risk group persons attending the various outdoor patient departments of BYL Nair Municipal Hospital, Mumbai. This study indicates that although HIV-1 is still the predominant virus among the high risk HIV infected persons in Mumbai, dual HIV-1-2 infections are increasing especially among promiscuous heterosexuals and female commercial sex workers. Increases in HIV-2 infections were observed later than dual HIV-1-2 infections, indicating that it is the HIV-1 infected individuals who through continued high risk behavior got infected by HIV-2.

Humoral and cell mediated immune responses in patient with tuberculous meningitis.

A study was carried out to find out the humoral and cell mediated immunity levels in patients with TBM and healthy controls. For humoral immunity, the amounts of immunoglobulins--IgG, IgM and IgA were quantitated by SRID method. For cell mediated immunity, percentages of total T cells, Th cells and Ts cells and the ratio of Th:Ts cells was studied.

Detection of antibodies to HIV in saliva.

Background: Saliva has been recommended as an alternative non-invasive specimen for detection of antibodies to human immunodeficiency virus (HIV) because of the inherent disadvantages of using serum for such testing.

Methods: In a double-blind study, paired serum and saliva specimens were collected from 100 known HIV antibody seropositive and 100 seronegative individuals. The serum was tested in the conventional way while saliva was tested after modifying the routinely used serum enzyme-linked immunosorbent assay so as to detect antibodies to HIV from saliva.
