Evaluation of Norrish's equation for correlating the water activity of highly concentrated solutions of sugars, polyols and polyethylene glycols
(2010)
Abstract: Norrish’s equation, (aw = Xw exp (-K Xs 2), where aw is water activity, Xw and Xs molar fractions of water and solute, respectively, and K is the correlating constant), has been widely used to predict aw of aqueous ...

Determination of the moisture sorption behavior of osmotically dehydrated mackerel fillets by means of binary and ternary solutions
(Sage Publications Ltd, 2013-06)
In this study, the moisture sorption isotherm of osmotically dehydrated mackerel fillets (Scomber japonicus) was experimentally determined. The fillets were osmotically dehydrated with solutions of salt (NaCl) (120 and ...
Effects of nutrients on feeding activities of the pest termite Heterotermes tenuis (Isoptera : Rhinotermitidae)
(Wiley-Blackwell, 2008-07-01)
Heterotermes tenuis is a native termite of large negative impact on the Brazilian economy. Many studies have focused on optimizing the baiting method for termite control by improving its use and its efficacy. In order to ...
Gaseous exchanges, growth and foliar anatomy of sugarcane plants grown in potassium (K) deprived nutrient solution
(2015-01-01)
Potassium participates in the plant metabolism and has an important effect on stomata opening, the activation of some enzymes and the mobilization of solutes, with positive effects on photosynthate distribution. Thus, in ...
Enhancing the production of the fermentable sugars from sugarcane straw: A new approach to applying alkaline and ozonolysis pretreatments
(2021-02-01)
The present study, sugarcane straw residue (SCS) was submitted to a combination of mild alkaline pretreatment and ozone cycles in a rotary reactor aiming to obtain fermentable sugars. The SCS exposed to short ozone cycles ...
