Batch-type experiments were used to study competitive As(V) and P sorption on various soils and sorbent materials. The materials assayed were a forest soil, a vineyard soil, pyritic material, granitic material, coarsely and finely ground mussel shell, calcinated mussel shell ash, pine sawdust and slate processing fines. Competition between As(V) and P was pronounced in the case of both soils, g...

Fourteen strains of Grifola frondosa (Dicks.) S. F. Gray, originating from different regions (Asia, Europe and North America) were tested for lignin degradation, ligninolytic enzyme activities, protein accumulation and exopolysaccharide production during 55 days of cultivation on oak sawdust. Lignin degradation varied from 2.6 to7.1 % of dry weight of the oak sawdust substrate among tested stra...

The studies were carried out on heavy metal bioavailability and leachability during water hyacinth composting mixed with cattle manure, sawdust and natural zeolite. The water hyacinth, cattle manure and sawdust were taken in the 6:3:1 ratio with 5, 10 and 15% natural zeolite and composted for 30 days. The concentrations of nutrients and total heavy metals were increased during the process. Due ...

Metamorphosis in the fly (Musca domestica) involves extensive lysis, neurogenesis and reorganization of neural tissue. Despite this, two experiments are reported which show aspects of larval memory persist into the adult form. Experimental larvae were reared in sawdust scented with aversive odours (mint or geraniol). Control larvae were reared on plain sawdust. In blind post-metamorphosis testi...

In this study, the physical properties of briquettes produced from two different biomass feedstocks (sawdust and date palm trunk) and different plastic wastes, without using any external binding agent, were investigated. The biomass feedstocks were blended with different ratios of two waste from electrical and electronic equipment (WEEE) plastics (halogen-free wire and printed circuit boards (P...

In this work, a low-cost lignocellulosic adsorbent with high biosorption capacity is proposed, suitable for the efficient removal of hexavalent chromium from water and wastewater media. The adsorbent was produced by autohydrolyzing Scots Pine (Pinus Sylvestris) sawdust. The effect of the autohydrolysis conditions, i.e., pretreatment time and temperature, on hexavalent chromium biosorption was i...

The intrinsic properties of some materials, such as foams, porous materials and granular materials, are their ability to mitigation waves. In this study, we investigated the ability of granular materials in explosion-induced wave mitigation. The present study was carried out using numerical simulations with Autodyn hydro-code and experimental tests by shock tube. Two materials of sawdust and mi...

Adsorption capacity of Cr (VI) onto sawdust of aspen tree and activated sawdust, was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH , temperature, agitation speed, absorbent dose and particle size. Cr (VI) removal is pH dependent and caused to be maximum at pH 2.0. The amounts of Cr(VI) adsorbed increased with increas...
