the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
An Al/Stainless Steel/Al lamellar composite was produced by roll bonding of the starting sheets at 400 °C. Afterward, the roll bonded sheet was cut in half and the accumulative roll bonding (ARB) process at room temperature was applied seven times. As a result, the central steel layer fractured and distributed in the Al matrix among different layers introduced by the repetition of roll bonding ...
this study investigated the impact of explicit instruction of morphemic analysis and synthesis on the vocabulary development of the students. the participants were 90 junior high school students divided into two experimental groups and one control group. morphological awareness techniques (analysis/synthesis) and conventional techniques were used to teach vocabulary in the experimental groups a...
objective: the purpose of this study was to evaluate and compare the effect of storage time and conditions on dimensional stability of acrylic patterns. materials and methods: in this in vitro study, a cylindrical shaped metallic post-core was fabricated. impressions were made from this metallic model and 30 samples were prepared with duralay acrylic resin. the specimens were divided into three...
toury (1978:200) believes that translation is a kind of activity which inevitably involves at least two languages and two cultural traditions. being polite while asking for something takes place differently in different cultures and languages, therefore various strategies may be applied for making requests and also translation of them in order not to disturb or threaten the face or better to sa...
Introduction: The large body of research, from theorizing to empirical findings, suggests that positive cognitive Re-evaluation of trauma may further support positive post-traumatic outcomes by enhancing post-traumatic growth. The aim of this study was to investigate the direct and indirect role coping strategies, core beliefs disruption, social support, spirituality, religious cope and intrusi...
Several series of novel banana-shaped H-bonded symmetric trimers (with two H-bonds) and asymmetric heterodimers (with one H-bond) were self-assembled by appropriate molar ratios of proton donors (H-donors) and acceptors (H-acceptors). The influences of H-bonded linking positions and aromatic ring numbers (4-8 aromatic rings in the rigid cores) as well as the chain lengths (n, m = 12 or 16, resp...
within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...
Background: Aging come with muscle weakness and musculoskeletal-related pain. This study aimed to examine the effects of core stabilization exercise on ultrasonic changes of multifidus muscle and chronic low back pain of aged-women. Methods: Twenty-nine aged-women (69±3.4 year old) with chronic low back pain were allocated into core stabilization exercise (9 women) and control (20 women) gro...
Background and Aim: Various studies have shown that reliable bond at the root - post - core interfaces are critical for the clinical success of post - retained restorations. Severe stress concentration at post - cement interface increases post debonding from the root. To form a bonded unit that reduces the risk of fracture, it is important to optimize the adhesion. Therefore, some post surface ...
