Waste from pulp and paper mills consist of sugar-rich fractions comprising hemicellulose derivatives and cellulose by-products. A complete characterisation of the waste streams is necessary to study the possibilities of an existing mill. In this work, four chromatographic methods have been developed to obtain the most suitable chromatographic method conditions for measuring woody feedstocks, li...

At present, the problem of depletion forest resources and associated increase in export shoulder corresponding logistics costs are increasingly felt. Today, as one solutions to this issue, concept using timber terminals has been applied, when processing roundwood into a more appropriate form, including for transportation, is carried out close proximity cutting area. The overall efficiency affec...

800x600   introduction:  many items are needed for dressing including sterile dressing set, antiseptic and washing solutions, leucoplast tape, waste bin for infectious garbage, waste bin for noninfectious garbage, safe disposal trash for sharp cutting instruments, bedpan and sometimes drugs. all the items are laid out on a simple wheeled trolley. the multiplicity of items together with problems...

Raw materials are the largest cost component in pallet manufhcturing. The primary raw material used to produce pallet parts are pallet cants. Therefore, pallet cant quality directly impacts pallet part processing and material costs. By knowing the quality of the cants being processed, pallet manufacturers can predict these costs and improve manufacturing efficiency. The purpose of this study wa...

A typical case of multiple-use forest management (MFM) in Southwestern Amazon is the commercial harvesting or Brazil nut (Bertholletia excelsa) seeds and timber other tree species. Although most important non-timber product (NTFP) basin, species under serious threat due to deforestation may also be affected by overharvesting. However, selective logging coexisting with Bertholletia positively af...

Using cutting techniques we obtain the two-loop N = 4 super-Yang-Mills helicity amplitudes for four-gluon scattering in terms of scalar integral functions. The N = 4 amplitudes are considerably simpler than corresponding QCD amplitudes and therefore provide a testing ground for exploring two-loop amplitudes. The amplitudes are constructed directly in terms of gauge invariant quantities and ther...

This investigation was undertaken to determine the relative effects of recommended land spraying while drilling (LWD) loading rate application for a source of water-based drilling waste material on selected soil properties and phytotoxicity. Drilling waste material was obtained from a well where a nitrate gypsum water based product was used to formulate the drilling fluid. The fluid and associa...
