Radiolysis of the Extract from the Sawdust of the Ponderosa Pine
… acetone-hexane (1:4) extract of Ponderosa pine sawdust were exposed to gamma and ultraviolet radiation. The three solutions, including the original, were checked for antibiotic activity on: Staphylococcus aureus Escherichia coli and Bacillus cereus. Results indicated that each solution inhibited …

Bioremediation of ethanol in air using a gas-fluidized bioreactor
… the operation is in packed bed mode.Initially, sawdust was selected for use as a packing material. Due to the poor fluidization properties of sawdust, glass spheres were added. A mixture of sawdust and glass spheres remained well mixed during fluidization. In the mixture, interparticle forces …

Hotdog not hot dog: The phonological planning of compound words
… compounds composed of two free morphemes like sawdust or fishbowl are prepared for production at the segmental level in the same way that two-syllable monomorphemic words (e.g. bandit) are, or instead as sequences of separable words (e.g. full bowl or grey dust). The experiments demonstrated …

Co-conversion of Biomass with Plastics and Tires
… study was performed on steam co-gasification of sawdust and plastics (PE and PP) using Aspen Plus. The study determined the synergistic effects of mixing PE and PP (0-30%) with lignocellulosic biomass. Highest hydrogen concentrations of 64.58 % and 62.87 % were obtained respectively for …

Co-gasification of biomass and plastic waste in a bubbling fluidized bed reactor
… In this study, the gasification of pure birch sawdust wood (BSD) and pure rice husk (RH) was compared with mixtures where each BSD and RH was mixed with both LDPE and HDPE in the presence of three different bed materials, namely silica sand, olivine, and red mud. It was found that mixing the …

The wintering and calving of Angus beef cows on a sawdust pad : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Animal Science at Massey University
A system of wintering and calving beef cows on a sawdust cattle pad was compared with the traditional method of wintering unsupplemented cows on hill country pasture. Comparisons were made over four years, beginning in 1970. Two herds of Angus beef cows were used in the experiment. One herd was …

An investigation of the production of volatile organic compounds (VOCs) by <i>Trichoderma</i> spp. and their mode of action against <i>Serpula lacrymans</i>
… different media (malt extract, minimal media and sawdust) and 4 <i>S. lacrymans</i> isolates demonstrated that levels of inhibition were influenced by <i>Trichoderma </i>isolate, media type and sensitivity of the <i>S. lacrymans</i> strain. The growth inhibition of <i>S. lacrymans</i> consistently …
