We present a comprehensive study of pattern formation in single-field relaxational systems with field-dependent coefficients. A modulated mean-field theory leads to a form amenable to analysis via the geometric architecture developed in our earlier work for systems that exhibit phase transitions between global steady states [Phys. Rev. E 69, 011102 (2004)]. We demonstrate that the phase diagram...

The aim of this study was to investigate the effects of starters and storage temperature (4 ºC, 25 ºC) onmicrobiological and physicochemical properties, volatile compounds and sensory evaluation of kefir.Kefirs produced by KFA and Chr. Hansen starters were stored at 4 ºC and 25 ºC for 40 days. pH andacidity at 4 ºC did not change (p ≥ 0.05), while at 25 ºC pH and total solid decreased as well a...

this study was aimed at the evaluation of the influence of storage under various conditions on the relative concentrations of major protein fractions and their proportion in bovine serum. blood samples were taken from six dairy cattle of a low-land black spotted breed and its crossbreeds. the separated blood serum was fractioned into aliquots. one aliquot was analysed immediately after the sepa...

the effects of uv-c illumination at the dosage of 6.6 kj m-2 on postharvest quality of mango fruit cv. ‘kaew kamin’ during storage at 25 or 12°c were investigated. the changes in fresh weight, texture, ripening index (ri), peel and pulp colours, visual appearance, total carotenoids (tc) and ascorbic acid (asa) content were determined on days 0, 4, 8, 12 and 16 of storage. uv-c irradiation effec...

irradiation is known to inhibit waste in stored garlic. treatment time and optimum irradiation dosage are two key factors in achieving the least waste in this process. these two factors were investigated on white ecotype bulbs from hamedan, iran that were irradiated after harvest for 30 and 45 days using fast electrons at dosages of 0, 25, 50, 75, 100, and 150 gy. different properties of the ga...

effects of pre-storage application of salicylic acid (sa) and storage periods were investigated on phenylalanine ammonia lyase (pal) activity, chilling index (ci) and quality of pomegranate (punica granatum) cv. malase saveh. the results showed that with increase in sa concentration up to 2mm, ci and ion leakage (il) were reduced while pal activity being increased. the lower il and ci vc the hi...

the objectives of this paper were production of probiotic yoghurt using l. paracasei ssp. tolerans, and evaluation of ph changes, viable counts, and organoleptic properties of the produced yoghurt. it was observed that the ph decrease during the fermentation period was faster in the milk inoculated with l. paracasei ssp. tolerans plus starter culture. there was a gradual decrease in ph in both ...
