studies have tended to use multi-element analysis techniques to establish elemental patterns for selected functional areas or across sampling grids covering entire archaeological sites. Spatial patterns have been identified for particular elements, but the outstanding problem is the interpretation of the results. the essential approach has been to establish patterns and then to propose reasons....
An essential characteristic for high performance inherently hydrophobic membranes such as microporous high density polyethylene (HDPE) membranes is to have a hydrophilic surface. In this project, wet chemical functionalization as a facile and effective method was developed to give a hydrophilic property to HDPE membranes using polar functional groups. KClO3, K2Cr2O7 and KMnO4 were selected as o...
Due to the limited availability of wood, as highest quality raw material for production biomass pellets, increasing attention is being paid and use pellets from low-quality materials such different types agricultural waste. However, complex chemical composition these often leads various problems during their combustion. One biggest when it comes burning related low melting temperature resulting...
Several alternative methods for the disposal of chromated copper arsenate (CCA) treated wood waste have been studied in the literature, and these methods are reviewed and compared in this paper. Extraction experiments have been carried out on CCA treated wood and evaluated as a method to recover the metal compounds into either fresh wood preservatives or other useful industrial materials. Recyc...
Two common tree species, ash ( Fraxinus sp.) and oak Quercus sp.), could provide readily available media for denitrifying bioreactors that use wood-based carbon biological nitrate treatment. However, it is not known if the wood from Emerald Ash Borer-killed (EAB-killed) trees an effective source removal compared to other species or high-tannin nature of inhibits denitrification potential. This ...
In commercially grown Miscanthus × giganteus, despite imposing a yield penalty, postwinter harvests improve quality criteria for thermal conversion and crop sustainability through remobilization of nutrients to the underground rhizome. We examined 16 Miscanthus genotypes with different flowering and senescence times for variation in N, P, K, moisture, ash, Cl and Si contents, hypothesizing that...
The salient diagnostic pharmacognostical characters of the roots of Mollugo strica which sows promise as an antifertility drug for future have been studied. The young root is di-to-tri-arch, diarch conditions being most common. The cork cambium arises in the outermost layer of cortex forming 2-3 layers of cork cells on the outside and phelloderm towards the innerside. In the nature root, two co...
