if solid wastes are not collected and disposed properly, can cause environmental pollution which affect human health, animals and plants. also aesthetic aspect of solid waste disposal is important. therefore proper management is necessary. this study was carried out for the identification and classification of solid waste produced by oil drilling company temporary camps based on rcra act and un...

to evaluate the effect of application of municipal solid waste compost (mswc) on the accumulation of heavy metals of lead, nickel and cadmium in the soil under maize cultivation, a factorial experiment in base randomized complete block design (rcbd) with four different amounts of municipal solid waste compost (zero, 15, 30 and 60 tons ha-1) and time (compost applied once or twice) was performed...

the influence of leachate from open solid waste dumping near salhad stream (abbottabad, pakistan) was investigated to quantify the variations of water quality during august 2007 to april 2008. samples were collected from five different sites located along the salhad stream. two sites were located before the mixing of solid waste leachate with the surface water. one sampling site was of leach...

The environmental indicators and the classification of beach waste are essential tools to diagnose the current situation and to indicate ways to improve the quality of this environment. The purpose of this paper was to perform a quali-quantitative analysis of the beach waste on the Curva da Jurema Beach (Espírito Santo Brazil). Three transects were used with equidistant positioning over the tot...

We reintroduce an interpretation of the kth-fold self convolution of the Catalan numbers by showing that they count the number of words in symbols X and Y , where the total number of Y ’s is k more than the total number of X’s, and at no time are there more Y ’s than k plus the number of X’s. Using this, we exhibit some of the wide variety of combinatorial interpretations of the kth-fold self c...

Consider the random sequential packing model with infinite input and in any dimension. When the input consists of non-zero volume convex solids we show that the total number of solids accepted over cubes of volume λ is asymptotically normal as λ → ∞. We provide a rate of approximation to the normal and show that the finite dimensional distributions of the packing measures converge to those of a...

A number of previous studies determined dilute acid pretreatment conditions that maximize xylose yields from pretreatment or glucose yields from subsequent digestion of the pretreated cellulose, but our emphasis was on identifying conditions to realize the highest yields of both sugars from both stages. Thus, individual xylose and glucose yields are reported as a percentage of the total potenti...
