In recent years, sewage sludge (SS) and bio-waste management have attracted increasing environmental attention. this study, hydrothermal carbonization (HTC) technology is investigated in the framework of a co-treatment digestate (SSD) an organic fraction municipal solid waste (OW). The proposed configuration integrates HTC with anaerobic digestion (AD) inter-stage (AD1 + AD2). effects different...

The main drawback in the utilization of geothermal resources arises from precipitation secondary minerals within wells, pipelines, steam separators, turbines and other surface equipment form scales. Scale formation is an outcome alteration various rocks dissolved fluids that find their way into a reservoir. Once ascend to surface, hydrostatic pressure decreases toward phase separation level per...

{ This paper studies a stochastic particle method for the numerical treatment of Smoluchowski equation governing the coagulation of particles in a host gas. Convergence in probability is established for the Monte Carlo estimators, when the number of particles tends to in nity. The deterministic limit is characterized as the solution of a discrete in time version of the Smoluchowski equation. Un...

We prove that ergodicity of the horocycle ow on a surface of constant negative curvature is equivalent to ergodicity of the associated boundary action. As a corollary we obtain ergodicity of the horocycle ow on several large classes of covering surfaces. There are two natural \geometric ows" on (the unitary tangent bundle of) an arbitrary surface of constant negative curvature: the geodesic and...

Reliable estimates of river stream fl ow and fl ood zoning maps are needed for water resourcesmanagement such as fl ood mitigation, water supply, dam construction and irrigation. Flood zoning needsaccurate data and is one of the non-structural fl ood management methods. This paper describes theapplication of HEC-RAS and GIS model to determine fl oodplains maps for the part of Sardabrud Rivertha...

The characterization of two-phase flow has been commonly based on homogeneous wet capillary models, which are limited to heterogeneous porous media. In this work, pressure and relative permeability models for three systems derived, enable the analysis effect oil-wet ratio mechanism. pressures, permeabilities water cut curves simulated at primary drainage stage. results show that water-wet exhib...

Within the framework of a relativistic transport model (ART 1.0) for heavy-ion collisions at AGS energies, we study the transverse ow of pions with respect to that of nucleons using two complementary approaches. It is found that in central collisions pions develop a weak ow as a result of the ow of baryon resonances from which they are produced. On the other hand, they have a weak anti ow in pe...

Recent photo-identification and genetic studies have identified at least five discrete breeding populations in Australia Oceania: western (D), eastern (E (i)), New Caledonia (ii)), Tonga (iii)), French Polynesia the Cook Islands (F). Also evident are low levels of intermingling among consistent with degree differentiation. Photo-identification has confirmed linkages between Area V feeding areas...
