we proposed to use artificial channels in laboratory assays to expose periphyton to substancesreleased in rural environments in order to test the following hypotheses 1) a high concentration of humicsubstances decreases the biofilm biomass and alters its metabolism; 2) periphyton biomass and metabolism increase in response to nutrient addition in spite of the previous high nutrient concentratio...
This paper focuses on using the numerical finite volume method (FVM) and artificial neural network (ANN) in order to propose a correlation for computing the entrance length of laminar magnetohydrodynamics (MHD) channels flow. In the first step, for different values of the Reynolds (Re) and Hartmann (Ha) numbers (600<ReL increases.
Ligand-gated ion channels enable intercellular transmission of action potential through synapses by transducing biochemical messengers into electrical signal. We designed artificial ligand-gated ion channels by coupling G protein-coupled receptors to the Kir6.2 potassium channel. These artificial channels called ion channel-coupled receptors offer complementary properties to natural channels by...
Abstract The englacial and subglacial drainage systems exert key controls on glacier dynamics. However, due to their inaccessibility, they are still only poorly understood more detailed observations important, particularly validate tune physical models describing By creating artificial moulins – boreholes connected the system supplied with water from surface streams we present a novel method mo...
estimation of seepage from water channels are necessary in evaluating water productivity in agricultural sector as affected by floodwater spreading on plains and artificial recharge of groundwater. several empirical seepage equations have been developed for this purpose. previous research results in iran have shown lots of variation in the coefficients and the empirical equations change in diff...
