Solute Movement Patterns in Trickle Irrigated Tomatoes

Irrigation Strategies to Minimize Nitrate Leaching for Drip Irrigated Tomatoes

Sand Movement patterns in the south of Iran

Wind regime data from the Jask meteorological station from a 20-year statistical period (1985-2005) was analyzedusing the Fryberger method to investigate sand drift potential (DP) in this area. The resultant drift potential anddirectional variability of wind were calculated and illustrated. Average annual sand DP was estimated to be 460vector units (VU), and the sand flux is 51 m3/m.year. There...

Model of solute and water movement in the kidney.

Finite difference equations describing salt and water movement in a model of the mammalian kidney have been solved numerically by an extension of the Newton-Raphson method used for the medullary counterflow system. The method permits both steady-state and transient solutions. It has been possible to simulate behavior of the whole kidney as a function of hydrostatic pressures in renal artery, ve...

Cell volume control in three dimensions: Water movement without solute movement

Cell volume primarily represents the amount of water in a cell. Osmotically active metabolites and mechanical forces can cause changes in cell volume, but cell volume is under feedback control around a characteristic set point. Traditionally, the analysis of cell volume regulation treats the cell as a semipermeable bag with osmotic pressure converted to hydrostatic pressure at the membrane. How...
