the present study sought to examine whether a task-based approach could have an impact on raising awareness of collocations. moreover, it sought to investigate the facilitative role of consciousness-raising tasks of collocations in the communicative instances of use. to this end, 68 intermediate learners of english were selected via a placement test. the participants were taught with classroom ...
objective: polyphenol oxidase or ppo (ec 1.14.18.1) is considered the enzyme responsible for quality deterioration and browning in different fruits during postharvest period. the objective of this study was to evaluate the antibrowning (inhibition of polyphenol oxidase activity) effect of cysteine, ascorbic acid, citric acid, kojic acid and glycine at two different ph (6 and 7) in hawthorn. me...
Introduction: Hemodialysis patients often develop resistance to recombinant human erythropoietin due to functional Iron Deficiency. In these patients iron therapy can be hazardous leading to hemosiderosis. Recent studies have suggested that intravenous ascorbic acid may be able to improve this hyporeponsiveness. The aim of this study was to evaluate the effect of intravenous ascorbic acid on fu...
the following null hypothesis was proposed: there is no significant difference between the efl students listening comprehension development receiving pictorial cues and those receiving no cuse. to test the null hypothesis, 52 male and femal freshmen students of medicine studing at iran university of medical scinces were randomly selected from a total population of 72 students. to ensure that th...
Background and Objective: Epileptic seizures lead to a problem in learning and memory. In view of the protective effect of ascorbic acid (vitamin C), the aim of this study was to investigate the effect of this substance on impairment of learning and memory in an experimental model of temporal lobe epilepsy in kainate-epileptic rat. Materials and Methods: In this experimental study, rats were...
Many factors can affect wheat gluten properties and functionality. One of the most important, of these factors, is wheat bug damages. Insect injects a salivary proteinase into wheat kernel that results a significant weakening effect on the gluten, in substantial losses in physical quality, dough properties and baking performance. Bread baked with the insect – damaged flour had poor quality and ...
with the introduction of communicative language teaching, a large number of studies have concerned with students’ oral participation in language classrooms. although the importance of classroom participation is evident, some language learners are unwilling to engage in oral activities. this passivity and unwillingness to participate in language classroom discussions is known as “reticence”. rev...
A chemically modified carbon paste electrode with 2-chlorobenzoyl ferrocene (2CBF) and carbon nanotube (2CBFCNPE) was employed to study the electrocatalytic oxidation of ascorbic acid in aqueous solution using cyclic voltammetry, square wave voltammetry and chronoamperometry. The diffusion coefficient (D = 1.42 × 10-6 cm2 s-1), and the kinetic parameter such as ...
the postharvest life of cut eustoma grandiflorum flowers is limited in open flowers. therefore a factorial experiment based on a completely randomized design with ascorbic acid (asa) at 4 levels (0, 100, 200, 300mg l-1) and citric acid (ca) at 3 levels (0, 100, 200 mg l-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. results indicated that a significa...
Self-monitoring blood glucose (SMBG) meters are now commonly used in diabetes management. Many drugs, including ascorbic acid, are known to interfere with glucose measurements using these meters. However, so far, misdiagnosis caused by interference has rarely occurred at the conventional doses. Recently, intravenous high-dose ascorbic acid treatment has been widely used in 11,233 patients in 20...
