Consecutive Desulphurization of Coal with T. ferrooxidans and Acidianus brierleyi

hree different types of bituminous coal were subjected to microbial desulphurization in bench scale slurry reactors. Consecutive treatment with two microorganism species was used to test if different sulphur forms could be removed. The treatment started with the bacterium Thiobacillus ferrooxidans followed by the archaeon Acidianus brierleyi. Consecutive treatment did not desulphurize the three te

Photoinduced Electron Injection from Ru(dcbPY)2(NCS)2 to SnO2 and TiO2 Nanocrystalline Films.

Photoinduced electron injection from the sensitizer Ru(dcbpy)2(NCS)2 (RuN3) into SnO2 and TiO2 nanocrystalline films occurs by two distinct channels on the femto- and picosecond time scales. The faster electron injection into the conduction band of the different semiconductors originates from the initially excited singlet state of RuN3, and occurs in competition with intersystem crossing. The rate

A BEAST for prowling in trees

When searching for convolutional codes and tailbiting codes of high complexity it is of vital importance to use fast algorithms for computing their weight spectra, which corresponds to finding low-weight paths in their code trellises. This can be efficiently done by a combined search in both forward and backward code trees. A bidirectional efficient algorithm for searching such code trees (BEAST)

Factors Affecting Coronary Flow in Children

Factors Affecting Coronary Flow in Children Elhadi H. Aburawi, MD, MSc, FRCPI, FRCPCH Division of Paediatric Cardiology, Department of Paediatrics, Lund University, Sweden Abstract Background: A number of inborn and exogenous factors influence the flow and function of the coronary arteries with possible consequences on the cardiovascular risk. The regulation of the coronary flow is partly dep

Differential scanning calorimetric studies of a Bacillus halodurans alpha-amylase

The thermal unfolding of Amy 34, a recombinant alpha-amylase from Bacillus halodurans, has been investigated using differential scanning calorimetry (DSC). The denaturation of Amy 34 involves irreversible processes with an apparent denaturation temperature (T-m) of 70.8 degrees C at PH 9.0, with four transitions, as determined using multiple Gaussian curves. The T-m increased by 5 degrees C in the

Cross-contamination in dishwashers

Dishwashers are used in central hospital kitchens and ward kitchens to provide clean crockery. Soil recipes based on international standards were tested in order to evaluate the performance of a general dishwasher. In normal use of dishwashers, adherent soils are left on the crockery before cleaning. Different adherent soils, both with and without bacterial. contamination, were used to show the ef
