DURING the past five years this problem of the evaporation of water from animals has attracted considerable attention, particularly from entomologists. Considerable advances have been made, but when the technique of various workers is examined from a physical standpoint it is difficult to see how far laboratory results can be applied to ecological problems in the field. During the last two year...

Present investigation describes preparation of microspheres by solvent evaporation and W/O emulsion solvent evaporation methods followed by in vitro characterization of microspheres to evaluate the effect of method of preparation on physical properties and drug release profile of microspheres. The microspheres were found to be discrete, spherical with free flowing properties. The morphology (Sc...

A multi-year, multi-technique study was conducted to measure evapotranspiration and its components within an uneven-aged mixed deciduous forest in the Southeastern United States. Four different measurement techniques were used, including soil water budget (1 year), sap flow (2 years), eddy covariance (5 years), and catchment water budget (31 years). Annual estimates of evapotranspiration were s...

We report on experiments of droplet evaporation on a structured superhydrophobic surface that displays very high contact angle (CA ∼ 160 deg), and negligible contact angle hysteresis (<1 deg). The droplet evaporation is observed to occur in a constant-contact-angle mode, with contact radius shrinking for almost the entire duration of evaporation. Experiments conducted on Teflon-coated smooth su...

The precise determination of evaporation flux from liquid surfaces gives control over evaporation-driven self-assembly in soft matter systems. The Hertz-Knudsen (HK) equation is commonly used to predict evaporation flux. This equation states that the flux is proportional to the difference between the pressure in the system and the equilibrium pressure for liquid/vapor coexistence. We applied mo...

Abstract. Evaporation plays an important role in the water balance on a different spatial scale. However, its direct and indirect measurements are globally scarce accurate estimations challenging task. Thus correct process approximation modelling of terrestrial evaporation crucial part. A physically based 1D lumped soil–plant–atmosphere model (BROOK90) is applied to study parameter selection me...

Evaporation is one of the main components hydrological cycle, and its estimation crucial important for water resources management issues. Access to a reliable estimator tool evaporation simulation in arid semi-arid areas such as Iran, which lose more than 70% their received precipitation by evaporation. Current research employs Bayesian Regularization (BR) Scaled Conjugate Gradient (SCG) algori...
