Single-crystal bismuth thin films 1 to 20 micrometers thick were fabricated by electrodeposition and suitable annealing. Magnetoresistance up to 250 percent at 300 kelvin and 380,000 percent at 5 kelvin as well as clean Shubnikov-de Haas oscillations were observed, indicative of the high quality of these films. A hybrid structure was also made that showed a large magnetoresistive effect of 30 p...

The professional dental literature is lacking in information concerning the use of technology in evaluation procedures utilized in postgraduate dental education. The purpose of this study was to identify the methods of evaluation of U.S. postgraduate specialty residents currently in place. The study also sought to determine if there were any patterns among programs more likely to utilize electr...

Lahnsteiner F. (2017): Digestive enzyme system of larvae of different freshwater teleosts and its differentiation during the initial phase of exogenous feeding. Czech J. Anim. Sci., 62, 403–416. Activities of digestive enzymes and main histological characteristics of the intestine were investigated in larvae of three salmonid species (Coregonus maraena, C. atterensis, Thymallus thymallus), of b...

Based on induration of less than 10 mm at 48 and 72 hours, 49 of 200 (25 percent) patients with active pulmonary tuberculosis failed to respond to intermediate (5TU) strength PPD. Distribution of reactors vs nonreactors was similar with regard to sex but not race, with more white subjects proving to be nonreactive. Additional comparisons between the two groups revealed significantly higher valu...

Asia Pacific is experiencing multiple dynamics of urbanisation, economic growth, poverty and environmental deterioration. It is the largest region with more than 60 percent of the world population. About 43 percent of the total population in the region live in urban areas, of which 40 percent live in slums and substandard conditions. In the past 30 years, the urban population in Asia Pacific ha...

Biodiesel is an alternative fuel derived from fatty acids in vegetable oils or animal fats. Because it contains almost no sulphur, it burns more cleanly than conventional diesel. However, the chemical reaction that breaks down the fatty acids into fuel relies on an aqueous alkali catalyst such as sodium hydroxide, making the product difficult to separate from the reaction mixture. Robert S. Wat...
