the aim of this study was to investigate the effect of the addition of commercial lipase in various forms on the acceleration of the ripening of uf-feta cheese. commercial lipase from aspergillus niger was encapsulated by using silica composition based on sol-gel method. lipase was then added to cheeses in three forms, namely, free lipase, encapsulated lipase, and encapsulated lipase with arabi...

abstract zinc (zn) is an essential plant nutrient. knowledge about distribution of zn between its different chemical forms is useful in understanding the chemistry of this element in soil and also in development of soil testing procedures. the present study was conducted to obtain such information about distribution of zinc forms in 20 soil samples of lorestan province by the use of a sequentia...

water saturation and cation exchange capacity are the most significant parameters used to calculate a hydrocarbon zone potential. in clean formations, by applying the famous archie model, which assumes that in the formation the only electric conductor is the formation water, the water saturation can be calculated. additionally, in shaly sand formations this assumption may not be true as the ion...

although some 3d slope stability algorithms have been proposed in recent three decades, still role of pore pressures in three dimensional slope stability analyses and considering the effects of pore water pressure in 3d slope stability studies needs to be investigated. in this paper, a limit analysis formulation for investigation of role of the pore water pressure in three dimensional slope sta...

1. The amount of free unfrozen water, i.e. water acting as normal solvent, in frog's muscle at temperatures below the initial freezing-point has been calculated from the vapour pressure isotherm of the muscle. 2. Significant amounts of free water are present at -20 degrees C. The total amount of unfrozen water at -20 degrees C. cannot, therefore, be taken as a measure of the bound water in musc...
