background & aim: chemicals antioxidants and lipid oxidation products are known as cancer-causing factors in food systems. in this study, the effect of essential oil from heracleum lasiopetalum fruits on lipid oxidation and physicochemical properties of potato chips in comparison with commercial antioxidant has been investigated.experimental: the essential oil of h. lasiopetalum extracted u...
Bleaching process is an essential stage in the refining of vegetable oils and fats. In this process the colour and the primary and secondary oxidation products are removed by the treatment with the acid activated bleaching earth .The aim of this project is to understand the effect of bleaching on the physical characteristics and chemical constituents of neutralized canola and sunflower seed oil...
monumental changes occurring on a daily basis have altered the world into a global village of expanding technology and shrinking geography in which preparing language learners for intercultural communication seems to be a sine qua non for modern language education. employing a cross-sectional design in its first phase, this study investigated the intercultural sensitivity and language proficien...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Oxidation in 3 types of bovine milk with different fatty acid profiles obtained through manipulation of feed was evaluated by analytical methods quantifying the content of potential antioxidants, the tendency of formation of free radicals, and the accumulation of primary and secondary oxidation products. The milk samples were evaluated in parallel by descriptive sensory analysis by a trained pa...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
The products of the primary OH-initiated oxidation of toluene were investigated using the turbulent flow chemical ionization mass spectrometry technique at temperatures ranging from 228 to 298 K. A major dienedial-producing pathway was detected for the first time for toluene oxidation, and glyoxal and methylglyoxal were found to be minor primary oxidation products. The results suggest that seco...
Introduction: Irradiation treatment is one of the best techniques to extend the shelf-life of meat, without emerging the nutritional properties and sensory quality of irradiated meat products. However electron -beam may cause transformations in foods but has been known as to the most easily-applied irradiation technique in food industries. Electron-beam irradiation is an environment...
