Development of corn and flaxseed snacks with high-fibre content using response surface methodology (RSM)
(INFORMA HEALTHCARELONDON, 2012)
With the increasing emphasis on health and well-being, nutrition aspects need to be incorporated as a dimension of product development. Thus, the production of a high-fibre content snack food from a mixture of corn and ...
New microsatellite markers for garlic, Allium sativum (Alliaceae)
(BOTANICAL SOC AMER INCST LOUIS, 2012)
Premise of the study: A new set of microsatellite or simple sequence repeat (SSR) markers for garlic, an important medicinal spice, was developed to aid studies of genetic diversity and to define efficient strategies for ...
Sampling, WLS, and Mixed Models
(AMER STATISTICAL ASSOC, 2011)
Mixed models may be defined with or without reference to sampling, and can be used to predict realized random effects, as when estimating the latent values of study subjects measured with response error. When the model is ...
FIA determination of ascorbic acid at low potential using a ruthenium oxide hexacyanoferrate modified carbon electrode
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The anodic oxidation of ascorbic acid on a ruthenium oxide hexacyanoferrate modified electrode was characterized by cyclic voltammetry. On this modified surface, the electrocatalytic process allows the determination of ...
A combined X-ray and theoretical study of flavonoid compounds with anti-inflammatory activity
(ELSEVIER SCIENCE BV, 2008)
The structure of 7,4`-dimethoxy-3`-acetylflavone (tithonin-Ac) has been determined by X-ray diffraction and its geometry is compared with optimized geometrical parameters obtained by means of density functional theory at ...
A novel HS-SBSE system coupled with gas chromatography and mass spectrometry for the analysis of organochlorine pesticides in water samples
(WILEY-V C H VERLAG GMBH, 2008)
A methodology to analyze organochlorine pesticides (OCPs) in water samples has been accomplished by using headspace stir bar sorptive extraction (HS-SBSE). The bars were in house coated with a thick film of PDMS in order ...
The use of a gold disc microelectrode for the determination of copper in human sweat
(ELSEVIER SCIENCE BV, 2010)
A novel approach of using a gold disc microelectrode to analyze sweat samples for copper ions by anodic square wave stripping voltammetry (SW stripping voltammetry) is described Sweat was collected from the lower back of ...
A compact and high-resolution version of a capacitively coupled contactless conductivity detector
(WILEY-V C H VERLAG GMBH, 2009)
An all-in-one version of a capacitively coupled contactless conductivity detector is introduced. The absence of moving parts (potentiometers and connectors) makes it compact (6.5 cm(3)) and robust. A local oscillator, ...
Thermoset matrix reinforced with sisal fibers: Effect of the cure cycle on the properties of the biobased composite
(ELSEVIER SCI LTD, 2009)
Thermoset phenolic composites reinforced with sisal fibers were prepared to optimize the cure step. In the present study, processing parameters such as pressure, temperature, and time interval were varied to control the ...
Characterization of protein hydrolysates of cosmetic use by CE-MS
(WILEY-BLACKWELL, 2011)
Protein hydrolysates have been used as active principles in cosmetic products conferring different properties to the final formulations, which are mostly controlled by the peptide size and its amino acid sequence. In this ...
