Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We discuss the influence of disperaion on solute movement for zero-order, first-order, and Michaelis-Menten kinetics. In general, dispersion enters both the transport equation and the boundary condition at the soil surface. The method of characteristics yi ...
The chondrocytes of adult articular cartilage rely upon transport phenomena within their avascular extracellular matrix for many biological activities. Therefore, changes in matrix structure which influence cytokine transport parameters may be an important ...
The mechanisms of water transport across the rabbit renal proximal convoluted tubule were approached by measuring osmotic permeabilities and solute reflection coefficients of the brush-border and the basolateral membranes. Plasma and intracellular membrane ...
Optimum growth conditions for the fermn. of nonconcd. whey permeate by K. fragilis NRRL 665 were defined. Use of 3.75 g yeast ext./L, a growth temp. of 38 Deg and a pH of 4.0 allowed a max. productivity of 5.23 g EtOH [64-17-5]/L-h in continuous culture wi ...
In the rabbit nephron, the luminal membrane surface area of the proximal convoluted tubule (PCT) is more than twice that of the proximal straight tubule (PST). What seemed to be an increase in histological specialization in solute and water transport is cu ...
The water permeability of ADH target epithelial cells is believed to be regulated by a cycle of exo-endocytosis of vesicles containing functional water channels. These vesicles were selectively labeled in intact frog urinary bladders with an impermeant flu ...
A general theory of vertical solute movement in a soil is presented, which takes into account uptake of water and solute by roots, irrigation or rainfall, and solute application and adsorption by the soil. Irrigation, rainfall, and the surface application ...
