GENESIS OF ACID-BASE SUPPORT PROPERTIES WITH VARIATIONS OF PREPARATION CONDITIONS: CUMENE CRACKING AND ITS KINETICS
(Industrial & Engineering Chemistry Research, 2013-01-16)
Different relative humidity conditions combined with chloride and sulfate salinity treatments modify abscisic acid and salicylic acid levels in the halophyte Prosopis strombulifera
It has been shown that abscisic acid (ABA) and salicylic acid (SA) act as endogenous signal molecules responsible for inducing abiotic stress tolerance in plants. However, our knowledge on the role of both phytohormones ...
Influence of concentration, time and method of application of citric acid and sodium citrate in root conditioning.
The aim of this study was to establish the parameters of concentration, time and mode of application of citric acid and sodium citrate in relation to root conditioning. A total of 495 samples were obtained and equally ...
2,4-Dichlorophenoxyacetic acid (2,4-D) degradation promoted by nanoparticulate zerovalent iron (nZVI) in aerobic suspensions
Reactive species generated by Fe0 oxidation promoted by O2 (catalyzed or not by ligands) are able to degrade contaminant compounds like the herbicide 2,4-dichlorophenoxyacetic acid. The degradation of 2,4-D was influenced ...
Effect of L-malic and citric acids metabolism on the essential amino acid requirements for Oenococcus oeni growth
(Wiley Blackwell Publishing, Inc, 2002-08)
Aims: The purpose of this work was to study the effect of L-malic and/or citric acids on Oenococcus oeni m growth in deficient nutritional conditions, and their roles as possible biosynthetic precursors of the essential ...

Sister-chromatid exchanges in β-thalassaemic patients under conditions of in vivo and in vitro depletion of folic acid
In order to investigate the effect of folate depletion, lymphocyte sister-chromatid exchange (SCE) rates were compared among homozygous β-thalassaemic patients with low folic acid levels, heterozygous β-thalassaemic patients ...
Chemical characterization of tall oilCaracterização química do crude tall oil
Tall Oil is considered one of the cheapest natural oils in the world, since it is an industrially generated by-product, not dependent on climatic and soil weather, but on the production of cellulose and kraft paper. The ...
