New starches for the food industry: Curcuma longa and Curcuma zedoaria
(Elsevier B.V., 2014)
Velocity‑vorticity‑pressure formulation for the Oseen problem with variable viscosity
(2021)
We propose and analyse an augmented mixed finite element method for the Oseen equations written in terms of velocity, vorticity, and pressure with non-constant viscosity and homogeneous Dirichlet boundary condition for the ...
Uma experiência didática sobre viscosidade e densidade
(2012)
In this work, a teaching experience is proposed in order to evaluate and differentiate, in a simple and clear way, two intrinsic properties of matter that make part of daily vocabulary, viscosity and density. To this end, ...
Assessment of the quality of heated oils by differential scanning calorimetry
(AMER CHEMICAL SOC, 1998)
Differential scanning calorimetry (DSC) was used to follow changes in the thermal characteristics of commercial frying oils (sunflower seed, colza, and groundnut) during heating at 180 degrees C for up to 10 h. DSC tracings ...
Does viscosity describe the kinetic barrier for crystal growth from the liquidus to the glass transition?
(2010)
An analysis of the kinetic coefficient of crystal growth, Ukin , recently proposed by Ediger and colleagues [J. Chem. Phys. 128 (2008) 034709] indicates that the Stokes-Einstein / Eyring (SE/E) equation does not describe ...
Análise reológica de azeite de abacate em diferentes temperaturas
(Universidade Tecnológica Federal do ParanáLondrinaBrasilTecnologia em alimentosUTFPR, 2014-08-05)
The avocado is a abundant fruit in Brazil, thus, its oil can be a product produced nationally at lower cost, substituting olive oil in the diet of the population and in food manufacturing, well studies show that the ...
Physicochemical properties of cassava starch oxidized by sodium hypochlorite
(2012-09-26)
In this work, cassava starch was modified by treatment with sodium hypochlorite (NaClO) at different concentrations (0.8, 2.0 and 5.0 % of active chlorine) and selected physicochemical properties of the oxidized starches ...

Poly(complexes) stabilized by acid-base interactions: Poly(4-vinylpyridine) and poly(ethylene-co-maleic acid)
(Taylor and Francis Inc., 1998)
Interpolymer complex (IC) formation between poly(ethylene-co-maleic acid) and poly(4-vinylpiridine) (P4VPy) has been observed and characterized. Data from viscosity, infrared spectroscopy and thermogravimetric analysis ...
