Crystallinity, thermal and pasting properties of starches from different potato cultivars grown in Brazil
Starches from different potato cultivars were characterized as amylose and phosphorus content, crystallinity, thermal and paste properties. Statistical analysis of amylose content showed difference between starches samples ...
Evaluation of extraction method on the structure and physicochemical properties of starch from seeds of two jackfruit varieties
Two main varieties of jackfruit (soft and hard) are commonly known in Brazil and contain a large amount of starch. This work aimed to evaluate the effect of extraction methods (aqueous and alkaline treatments) on the ...
Assessment of sugar cane straw ash (SCSA) as pozzolanic material in blended Portland cement: Microstructural characterization of pastes and mechanical strength of mortars
Abstract The aim of this paper is to assess the pozzolanic reactivity of sugar cane straw ash (SCSA) obtained through an auto-combustion process and the mechanical properties of SCSA-containing systems. Characterization ...

(Revista Ceres, Viçosa, MG, v. 59, n. 1, p. 16-24, jan./fev. 2012., 2012)
Effect of EVA on the fresh properties of cement paste
(ELSEVIER SCI LTDOXFORD, 2012)
The improved workability effect of latex in dry mortars has not been fully clarified. The purpose of this research was to investigate the influence cif the EVA copolymer on the cement hydration and on the rheological ...
Effect of different treatments on the microstructure and functional and pasting properties of pigeon pea (Cajanus cajan L.), dolichos bean (Dolichos lablab L.) and jack bean (Canavalia ensiformis) flours from the north-east Argentina
(Wiley Blackwell Publishing, Inc, 2017-01)
The effect of germination (G; 5 days), soaking-cooking (SC; 6 h–20 min, 6 h–40 min, 6 h–60 min) and microwave (M; 50%, 70%, 100%) treatments on pigeon pea (PP), dolichos bean (DB) and jack bean (JB) seeds was studied. ...
Determination of nitrendipine with β-cyclodextrin modified carbon paste electrode
Carbon paste electrodes modified with β-cyclodextrin have been investigated for voltammetric determination of nitrendipine. The immobilization of the β-cyclodextrin on the carbon paste leads to a modification of the electrode ...
TEMPERTURE INFLUENCE ON THE RHEOLOGICAL BEHAVIOUR OF CEMENTITOUS PASTES PREPARED WITH AIR-ENTRAINING ADMIXTURES
(KERSCHENSTEINER VERLAG GMBHLAPPERSDORF, 2012)
Cementitious pastes prepared with air-entraining admixtures (AEA) are very sensitive to mix procedures and environmental conditions. Some of the effects of AEA on the properties of cementitious material are discussed in ...
