Synthesis, Characterization, Optical, Electrochemical and Current-Voltage Characteristics of Coumarin Dyes.

A series of coumarin dyes having common acceptor and pi spacer with different donors were synthesized and characterized by spectroscopic techniques. The TiO nanoparticle has been synthesized by sol-gel method and characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy. Photophysical and electrochemical properties have been investigated.

Episode of coexisting infections with multiple dengue virus serotypes in central Karnataka, India.

Background: The co-circulation of multiple dengue virus serotypes has been reported in many parts of the world, including India; however, concurrent infection with more than one serotype of dengue virus in the same individual is rarely documented.

Method: An outbreak of dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS) occurred in and around Davangere, Karnataka, from June 2011-March 2012. This is the first report from India with a high percentage of concurrent infections with different dengue virus serotypes circulating during one outbreak.

Carbon particles in airway macrophage as a surrogate marker in the early detection of lung diseases.

Background: It has been shown that inhalation of carbonaceous particulate matter may impair lung function in children.

Objective: Using the carbon content of airway macrophages as a marker of individual exposure to particulate matter derived from fossil fuel, we sought direct evidence for this association.

Methods: 300 children from puffed rice industrial areas and 300 children from population living in green zone were selected randomly.

Isolation of bacteriophages to multi-drug resistant Enterococci obtained from diabetic foot: a novel antimicrobial agent waiting in the shelf?

Introduction: While foot infections in persons with diabetes are initially treated empirically, therapy directed at known causative organisms may improve the outcome. Many studies have reported on the bacteriology of diabetic foot infections (DFIs), but the results have varied and have often been contradictory. The purpose of the research work is to call attention to a frightening twist in the antibiotic-resistant Enterococci problem in diabetic foot that has not received adequate attention from the medical fraternity and also the pharmaceutical pipeline for new antibiotics is drying up.

Detection of extended spectrum beta-lactamase from clinical isolates in Davangere.

Extended spectrum beta-lactamase enzymes (ESBLs) are enzymes that have the ability to hydrolyze oxyiminocephalosporins and infections by isolates producing them are often difficult to treat. A study to detect the presence of these enzymes in isolates was conducted by our hospital. A total of 207 non repetitive isolates were screened for resistance to any of five screening agents.

Study of bacterial, fungal, and parasitic contaminaiton of currency notes in circulation.

A total of 100 currency notes of various denominations in circulation were randomly studied for bacterial, fungal and protozoal contamination. All except four notes yielded one or more bacteria. Bacterial culture yielded single isolate in 33 notes, two in 44 notes, three in 12 notes and four in 7 notes.

Living arrangements and residential overcrowding among older immigrants in Canada.

"Because older immigrants arriving in Canada are not eligible for government transfer payments or welfare benefits for up to 10 years, many of them choose to live with their relatives or sponsors in crowded three- or more than three-generation households. Cultural preferences also influence this tendency and the propensity of immigrant groups from developing regions to live in three- or more than three-generation households ranges up to 18 times those of their Canadian-born and immigrant counterparts from the developed regions. Variables such as average income, percent receiving Old Age Security payments, percent widowed and duration of residence in Canada are significantly associated with proportions of immigrants living in such arrangements, and explain about 84 percent of birthplace variation for males and 81 percent for females.

Asian immigrants in Canada: some findings from 1981 census.

Immigrant characteristics in Canada are analyzed using data from the 1981 census. "The purpose of this paper is to focus on Asian immigrants and to compare them with immigrants born in the United Kingdom, and also to compare them with Canadian-born persons with respect to age, sex, marital status composition, educational attainment, labour force participation, class of worker, occupation and income."

The influence of fluctuations in economic conditions on fertility and marriage rates, Australia, 1920-21 to 1937-38 and 1946-47 to 1966-67.

Abstract It has been widely observed that both cross-sectionally and secularly there has been a negative relationship between income or level of living and the family size of married females. 1 At the same time the relationship between economic indicators and current fertility with a lag of one or more years over the business cycle has been found to be strongly positive. In fact the persistence of the latter relationship over a wide area and varying periods led Dr.
