Bovine spongiform encephalopathy (BSE) is one of the fatal neurodegenerative diseases known as transmissible spongiform encephalopathies (TSEs) caused by infectious prion proteins. Genetic variations correlated with susceptibility or resistance to TSE in humans and sheep have not been reported for bovine strains including those from Holstein, Jersey, and Japanese Black cattle. Here, we investigated bovine prion protein gene (PRNP) variations in Hanwoo cattle [Bos (B.) taurus coreanae], a native... -
Purification and Characterization of a Major Extracellular Chitinase from a Biocontrol Bacterium, Paenibacillus elgii HOA73

7, although its activity was stable when incubated between pH 3 and pH 11. Heavy metals inhibited this chitinase. This purified chitinase completely inhibited spore germination of two Cladosporium isolates and partially inhibited germination of Botrytis cinerea spores. However, it had no effect on the spores of a Colletotricum isolate. These results indicate that the extracellular chitinase produced by P. elgii HOA73 might have function in limiting spore germination of certain fungal pathogens. -
Formation of nanojoints between carbon nanotubes and copper nanoparticles

smaller dimensions and higher conductivity as compared to copper, multi-walled carbon nanotubes (MWCNT) may increase the bandwidth density of global interconnects [4]. They demonstrate charge carrier mean free paths between 500 nm and 10 μm as compared to 40 nm in metals. CNTs can carry exceptionally high current densities of up to 1010 A cm?2 even at elevated temperatures [5,6]. CNTs are expected to demonstrate resistance to electromigration higher than that of Cu-based interconnects [7]. -
Preparation and characterization of microporous NaOH activated carbons from hydrofluoric acid leached rice husk and its application for lead(II) adsorption
A. F. Hassan, A. M. Youssef 한국탄소학회 Carbon Letters 10 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.1 8 57-66 (10 pages)
Three activated carbons (ACs) were prepared using NaOH (N) as an activating agent. Hydrofluoric acid pre-leached rice husk was used as a precursor. After leaching, the precursor was washed with distilled water, dried, crushed, and then sieved; a size fraction of 0.3-0.5 mm was selected for carbonization in the absence of air at 600°C. The carbonization product (LC) was mixed with NaOH at ratios of 1:2, 1:3, and 1:4 (wt of LC: wt of NaOH) and the produced ACs after activation at 800°C were... -
