Background and objectives: Safflower (Carthamus tinctorious L.) florets contain valuable red and yellow pigments and are used in food, textile dying, and pharmaceutical industries. Red carthamine pigment is formed from a yellow precursor, precarthamine, through an oxidation reaction at the end of flowers' maturation stage. The present study was conducted to find out the most effective ...

The total thickness of the skin heifers four groups increased from 3 to 18 months postnatal ontogenesis, depending on breed, by 16–27 %. In base and original genotype breeds, different periods completion growth were established. all heifers, there fundamental differences in dynamics outer integument. epidermal layer reached maximum values early ontogeny heifers. layers dermis with age, 33–43 % ...

In this study, 115 samples taken from the stream sediments were analyzed for concentrations of As, Co, Cr, Cu, Ni, Pb, W, Zn, Au, Ba, Fe, Mn, Sr, Ti, U, V and Zr. In order to outline mineralization-derived stream sediments, various mapping techniques including fuzzy factor score, geochemical halos and fractal model were used. Based on these models, concentrations of Co, Cr, Ni, Zn, Ba, Fe, Mn, ...

background the effect of pyocyanine pigment, which was isolated and purified from pseudomonas aeruginosa, on specific lymphocytes viability inside the body of white male balb/c mice against the experimental secondary hydatidosis and the infectivity of protoscolices was studied in comparison with negative control mice groups, phosphate buffered saline (pbs) and positive control group (immunofero...

As a key part of the brain's reward system, midbrain dopamine neurons are thought to generate signals that reflect errors in the prediction of reward. However, recent evidence suggests that "upstream" brain areas may make important contributions to the generation of prediction error signals. To address this issue, we recorded neural activity in midbrain reticular formation (MRNm) while rats per...

In the present work the magnitudes of pigments in the synthetic leather, were measured by means of scanner. Initially synthetic leather samples pigmented by three different pigments of yellow, blue and red colors were prepared. Then the pigmented samples were scanned, and the values of RGB of images were calculated. The artificial neural network (ANN) method used to make relation between RGB va...
