the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
The purpose of this study was to evaluate angiogenesis after the use of intramedullary direct electrical current in rabbit tibia. Thirty-two New Zealand rabbits were divided into four groups: group 1, false electrode group; group 2, hole group; group 3, control group; and group 4, intramedullary electrical stimulation group. One-half of the rabbits in each group were evaluated angiographically,...
Mixed-reality games have the potential to let users play in the world surrounding them. However, to exploit this new approaches to game content creation, content presentation techniques and interaction techniques are required. In this paper we explore the potential of computer-vision on mobile devices with a camera as an interaction modality. Based on a theoretical review of the available desig...
Although subcutaneous adipose tissue undergoes large deformations on a daily basis, there is no adequate mechanical model to describe the transfer of mechanical load from the skin throughout the tissue to deeper layers. In order to develop such a non-linear model, a set of experimental data is required. Accordingly, this study examines the long term behavior of adipose tissue under small strain...
The present experiment examined the effects of food deprivation upon predatory attack elicited by electrical stimulation of lateral hypothalamic sites in the cat. Latencies for attack initiation and for object contact were assessed under ad libitum feeding conditions and compared, in a within-subjects design, to attack latendes following 72 hr of food deprivation. Both initiation and object con...
STATEMENT OF PROBLEM The choice of single-molar implant design is difficult because of a lack of controlled, quantitative biomechanical analyses. PURPOSE This study determined the effect of 3 single-molar implant designs on implant strains under a variety of homologous loading conditions. MATERIAL AND METHODS On each implant abutment, 4 strain gauges were placed axially at 90 degrees to eac...
current studies in second language (l2) learning have revealed the positive role of corrective feedback (cf) in both oral and written forms in different language features. the present study was an attempt to investigate the effect of both direct and indirect written corrective feedback (wcf) on the use of grammatical collocations in l2 writing. the study also sought to examine whether the effec...
