the present study is an attempt to contribute to the l2 acquisition research through finding an appropriate answer to the question usually asked by both language teachers and learners, namely how to learn vocabulary and how to retain meanings in memory over time. we have chosen to discover the effects of two major types of productive exercises, writing and oral production exercises, on the reme...

The aim of this study was to compare the ability of 46 isolates of Candida albicans to produce mycelial form with oral source in three groups of individuals including, removable appliance wearers, non-wearers and oral medicine patients. Saliva samples were obtained from all subjects along with a foam imprint from the fitting surface of the upper removable appliance in the case of patients. Colo...

Antibody production and clinical efficacy (relative percent survival RPS) were measured in 40±5g rainbow trout after immunization with two types of Streptococcus iniae vaccines consisting of formalin killed cells (FKC) and FKC enriched with the bacterial extracellular products (ECP) administered by intraperitoneal (i.p), immersion and oral routes at 16±1°C for 18 weeks. No significant differenc...

BACKGROUND Acetaldehyde has been implicated as a major factor in oral carcinogenesis associated with alcohol consumption. In this study, saliva samples from oral cancer patients and healthy individuals were incubated in vitro with ethanol in order to investigate factors which can influence salivary acetaldehyde production. MATERIALS AND METHODS A total of 66 individuals (40 males and 26 femal...

This study explored the effect of contrastive phrase resynthesis instruction ongaining the teachability hypothesis stages in self-paced versus time-constrained oralproduction and recognition. Three groups (i.e., 23 learners) of high beginner femalelearners in an English language institute were randomly selected from a cohort oflearners. One group received contrastive metalinguistic instruction ...

Researchers have extensively studied phenomena that affect a second language learner’s oral production while there is scant evidence about input-related factors. Accordingly, the present study sought to investigate how variation in oral production is caused by the input they receive from different course materials. To this end, the study included a micro-evaluation study of three course materia...
