We extend the mechanism for noise-induced phase transitions proposed by Ibañes et al. [Phys. Rev. Lett. 87, 020601 (2001)] to pattern formation phenomena. In contrast with known mechanisms for pure noise-induced pattern formation, this mechanism is not driven by a short-time instability amplified by collective effects. The phenomenon is analyzed by means of a modulated mean field approximation ...

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

We analyze pattern formation in doubly resonant intracavity second-harmonic generation in the presence of competing nondegenerate parametric downconversion. We show that for positive cavity detuning of the fundamental frequency the threshold for parametric oscillation is lower than that of transverse, pattern forming instabilities. The parametric oscillation strongly modifies the pattern dynami...

Introduction: Aflatoxin M1 is an important mycotoxin frequently found in milk and dairy products. The main objective of this work was to study the stability of AFM1 during production and refrigerated storage of probiotic yogurt. Materials and methods: Two kinds of probiotic yogurt were made by cow’s milk artificially contaminated with aflatoxin M1 at a level of 100 ng/l, and fermented...

In the present study, the effect of addition of flaxseed mucilage on the physicochemical and sensorial properties of semi-fat (1.5% fat) set yoghurt was evaluated. Yoghurt samples were incorporated with flaxseed mucilage at the levels of 0.00, 0.10, 0.15, and 0.20% and analyzed periodically for pH value, titrable acidity, viscosity, consistency, water holding capacity, syneresis, colour paramet...

Three potato cultivars (Solanum tuberosum L.), spring Marfona, autumn Cosima and Marfona, obtained from Isfahan Province, were stored under different conditions: 4oC, darkness 12oC, fluorescent light room temperature, darkness and room temperature, daylight. Relative humidity of the above stores was 85 to 90%. Analyses were carried out to determine total glycoalkaloids, α-solanine, specific gra...
