(Dated: February 1, 2008) A normal-fluid component varying as T is observed at very low temperatures in superfluid He and He-He mixture films adsorbed in alumina powder. The normal fluid appears to arise from thermally excited third sound that has one-dimensional propagation characteristics. A Landau model of third sound excitations in an infinite cylindrical pore by Saam and Cole provides good...

Effects of deglucosing and antioxidant treatments on quality characteristics of broiler blood meal were studied. Broiler blood was dried and ground with deglucosing and antioxidant addition. The non-deglucosed blood powder was darker, less red and yellow in color than those of the deglucosed. Yeast deglucosed blood meal had the lowest lysine availability as measured by the ̄uorodinitrobenzene me...

In order to achieve a homogeneous starting material for the production of dense Si3N4 by post-sintering of RBSN, the morphological and chemical characteristics of the Si-starting powders as well as the pore structure of the Si-powder compacts have to be optimized. In this context, the influence of the grain size distribution on the micropore size distribution of the Sipowder compacts was determ...

This research work investigates the efficiency of H3PO4and KOH impregnated jackfruit leaf powder based carbon as adsorbent to remove Ni from wastewater. The removal characteristics of Nickel using both the adsorbents were investigated under various operating variables like contact time, adsorbent dosage, initial metal concentration, solution pH, temperature and stirring speed. The results showe...

In industrial use of paint systems a swift processing is crucial. Another very important issue is to improve the quality of the final coating. This report investigates the film formation process of powder coatings, specially the spreading of individual powder particles. The obtained results can be used to understand and control the film formation process. In this way the desired levelling can b...
