Activity of water in aqueous systems; A frequently neglected property [PDF]

, 2005
In this critical review, the significance of the term ‘activity’ is examined in the context of the properties of aqueous solutions. The dependence of the activity of water(ℓ) at ambient pressure and 298.15 K on solute molality is examined for aqueous ...

USE OF AIC AND BIC IN DESORPTION ISOTHERMS OF TAMARIND SEEDS (Tamarindus indica L.) [PDF]

Engenharia Agrícola, 2020
The knowledge of hygroscopicity is essential for the storage of tamarind seeds, but there is a limitation of a judicious statistical parameter to define the best mathematical model to adjust the isotherms of plant products. Therefore, this study aimed to

The effects of water and microstructure on the performance of polymer electrolyte fuel cells [PDF]

, 2006
n this paper, we present a comprehensive non-isothermal, one-dimensional model of the cathode side of a Polymer Electrolyte Fuel Cell. We explicitly include the catalyst layer, gas diffusion layer and the membrane.

Effect of macromolecular crowding on the kinetics of glycolytic enzymes and the behaviour of glycolysis in yeast [PDF]

, 2018
Water is involved in all aspects of biological activity, both as a solvent and as a reactant. It is hypothesized that intracellular water is in a highly structured state due to the high concentrations of macromolecules in the cell and that this may ...

Effects of Altering Freshwater Chemistry on Physiological Responses of Rainbow Trout to Silver Exposure [PDF]

, 1999
The influence of different water Cl- (50–600 μM), Ca2+ (50–1,500 μM), Na+ (50–1,500 μM), or dissolved organic carbon (DOC, 0.31–5 mg/L) levels on silver-induced physiological and biochemical perturbations of rainbow trout were investigated.
