Marigold flower extract (MFE), a natural source of xanthophylls, was added to the diets of hens at different concentrations (0, 150, 250, and 350 mg/kg of diet) to determine the effects of MFE on hen performance, physical characteristics of egg quality, and carotenoid content of the egg yolk of hens housed in enriched cages. Additionally, the highest dose of MFE (350 mg/kg) was tested under com...

key words: Silk, fibroin, accelerated ageing, condition, yellowness index, molecular weight, sorbed moisture To ensure continued access and long-term preservation it is essential to understand the condition of an artefact, and the behaviour of its component materials, in order to set limits on display and handling. In support of curators and conservators of collections with historic textiles, w...

BACKGROUND An effect of increased fruit and vegetable (FV) consumption on facial attractiveness has been proposed and recommended as a strategy to promote FV intakes, but no studies to date demonstrate a causal link between FV consumption and perceived attractiveness. This study investigated perceptions of attractiveness before and after the supervised consumption of 2, 5 or 8 FV portions/day f...

Cassava is a starchy root crop cultivated in the tropics for fresh consumption and commercial processing. Primary selection objectives in cassava breeding include dry matter content and micronutrient density, particularly provitamin A carotenoids. These traits are negatively correlated in the African germplasm. This study aimed at identifying genetic markers associated with these traits and unc...

The absence of a final criterion poses an interesting problem about concept acquisition. On the standard stories about concepts, a person acquires a concept, and so constructs the corresponding psychological category, by stipulating, learning, or otherwise putting in place a final criterion for the category. On the Lockean and prototype theories, the final criterion is assembled from various ob...

ABSTRACT: Mustard is a natural multi-functional additive with strong hot flavor. In this research, powdered yellow mustard (Sinapis alba) was heated by 21 different thermal processes, statistically designed by Response Surface Methodology to evaluate the effects of combinations of heating media (hot air, hot water and steam) and heating time (0-20 min) on residual myrosinase activity, the minim...

Ultrasound technique was used to produce native and acetylated cassava starch particles containing potassium sorbate (KS). In order obtain an active packaging, films with addition of KS (NKSPF) or added (AKSPF) were formulated. As control systems, without (CF) that not retained in (KSF), produced. The NKSPF AKSPF microstructure consistent composite materials. Tensile test revealed CF KSF ductil...

Sixty rabbits from the 23rd generation (group S) of a line selected for growth rate were compared to sixty rabbits from the 7th generation of the same line (group C) to study possible relevant changes in carcass composition and meat quality due to the selection and the consequent decrease in degree of maturity at slaughter weight (2000g). The only relevant changes in carcass composition were an...

Tb4+-doped sodium zirconate samples, Na2Zr1−xTbxO3, were synthesized as novel environmentally friendly inorganic yellow pigments by a conventional solid-state reaction method. Their crystal structures, optical properties, and colors characterized. A single-phase form was obtained for the samples in x range of ≤ 0.18, while impurity phases detected sample with = 0.20. All showed strong absorptio...

This work was carried out on fresh samples of silicified sandstone and white conglomerate quarry from Zamora, Spain. The stones were treated with conservation treatments (H224, RC70, RC80) and/or processes freeze/thaw aging (similar to that cold areas). values obtained for the chromatic coordinates (L*, a*, b*) ultrasound propagation speed studied analyzed a statistical design created. In addit...
