sludge, which is produced as a by-product of all treatment processes, has considerable potential as a fertilizer and soil conditioner. many authorities now discharge the sludge after treatment directly to agricultural land in liquid form, while some others dewater and dry it first. in either case, with proper marketing, it is generally possible for an authority to earn revenue by this means, al...

Background Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the United States. Binge eating disorder (BED) is the most common form of eating disorder. NAFLD and BED have similar risk factors, including obesity, insulin resistance, and metabolic syndrome. The aim of our study was to examine prevalence of BED in NAFLD patients. Methods We administered the Binge Eati...

introduction: bridges are certainly one of the most important structures but costly service elements in a transport system. the bridges are very required to access the damaged areas in emergency situations such as floods and earthquakes. scour around the foundations of bridge piers exposed to the flowing water than can destroy the bridge itself is a subject of major concern. flow pattern is kno...

[1] We present a new 3-D cellular automaton model for bed form dynamics in which individual physical processes such as erosion, deposition, and transport are implemented by nearest neighbor interactions and a time-dependent stochastic process. Simultaneously, a lattice gas cellular automaton model is used to compute the flow and quantify the bed shear stress on the topography. Local erosion rat...

This paper considers the problem of spatiotemporal bed topography evolution and sediment transport estimation in rivers with migrating bed forms of different types and sizes, in statistical equilibrium conditions. Instead of resorting to bed form classification, we propose to evaluate the evolution of multiscale bed topography as the integral of unit contributions defined through a space-time F...

this paper presents an analytical model characterizing unsteady groundwater flow in an unconfined aquifer resting on a sloping impervious bed. the aquifer is in contact with a constant water level at one end. the other end is connected to a stream whose level is increasing form an initial level to a final level at a known exponentially decaying function of time. moreover, the aquifer is repleni...

the presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. the aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coefficie...
