Analytical solutions have been obtained for both conservative and non-conservative forms of one-dimensional transport and transport-dispersion equations applicable for pollution as a result of a non-conservative pollutant-disposal in an open channel with linear spatially varying transport velocity and nonlinear spatially varying dispersion coefficient on account of a steady unpolluted lateral i...

This paper presents (1) general considerations related to the development of two mathematical models for non-conservative transport of nitrate and ammonium under unsteady water flow conditions; (2) their application to predict the transport of pollutant in both customary and accidental pollutant release circumstances; and (2) a discussion related to models use in water quality management. The s...

Though runoff from manure spread fields is recognized as an important mode of nonpoint-source pollution, there are no models that mechanistically describe transport from a field-spread manure-type source. A mechanistic, physically based model for pollutant release from a surface source, such as field-spread manure, was hypothesized, laboratory tested, and field-applied. The primary objective of...

objectives:  to identify the predictive factors of successful non-operative management of patients with intraperitoneal bleeding following blunt abdominal trauma. methods:  this was cross-sectional study being performed in our level i trauma center in southern iran between 2010 and 2011. we included adult (>14 years) patients with blunt abdominal trauma and intraperitoneal hemorrhage detected b...

This paper investigates the nonlinear dispersion of a pollutant in non-isothermal incompressible flow temperature-dependent viscosity fluid rectangular channel filled with porous materials. The Brinkman-Forch-heimer effects are incorporated and is assumed to be variably permeable through channel. External injection, heat sources radiative flux Rossland approximation accounted for. system partia...
