characterization and utilization of fly ash derived from the co-combustion of biomass and coal as a mineral admixture for ordinary portland cement
(2009)co-firing coal with renewable/waste biomass for power generation can mitigate the atmospheric discharge of pollutants (e.g., so2) and green-house gases. wide-spread application of this technology is impeded, however, by ... -
the antifeedant action of climacodon septentrionalis and two species of sphaerobolus to hyphal grazing by the fungus-feeding nematode aphelenchoides sp.
(2012-11-10)fungi are ubiquitous in forest ecosystems and are, collectively, a major force in driving nutrient and organic matter availability and cycling. some saprotrophic and mycorrhizal fungi are characterized by a perennial ... -
attentional and psychophysiological responses to seasonal and eating stimuli in seasonal depression and disordered eating
(2012-11-10)research indicates similarities in clinical presentation between seasonal depression and bulimia nervosa with respect to disordered eating symptoms such as overeating, carbohydrate craving, weight gain and seasonal pattern ... -
habitat use by woodland caribou in a managed boreal forest landscape
(2012-11-10)woodland caribou (rangifer tarandus caribou) populations throughout much of the boreal forest have decreased as a result of changes to forest composition, including an increase in moose (alces alces) and wolf (canis lupus) ... -
integrated solar electrokinetic remediation of soil contaminated with copper
(2012-11-10)electrokinetic remediation is an emerging in-situ technology for cleaning contaminated soil. the contaminants are mobilized by passing a low-level direct current between a row of positively charged electrodes (anode) and ... -
positron/electron annihilation via the two-photon pathway
(2012-11-10)when a positron/electron pair annihilate via the two-photon pathway, the emitted photons are momentum correlated. this correlation ensures that they move along a straight line path in opposite directions. an experiment ... -
attitude estimation and stabilization of a quadrotor aircraft
(2011)in the past few years, researchers have shown great interest in quadrotor aircraft as a platform for uav research due to simplicity of construction as well as maintenance, ability to hover in small indoor locations or ... -
