The sociocultural approach to writing strategy use emphasizes the importance of context and the mediating resources that learners can use to enhance the quality of their performance in writing (Lei, 2008). Accordingly, the present study explored the sociocultural strategy use of a convenient sample of 105 BA level students of English Language and Literature who had passed essay-writing courses ...

Dendritic spines were considered an artifact of the Golgi method until a brash Spanish histologist, Santiago Ramón y Cajal, bet his scientific career arguing that they were indeed real, correctly deducing their key role in mediating synaptic connectivity. This article reviews the historical context of the discovery of spines and the reasons behind Cajal's obsession with them, all the way till h...

ICT-related change is usually studied from the point when a technological artifact has arrived in an organization. Applying an activity-theoretical lens, this paper explores the contradictions within a medium-sized organization’s central activity system, the manifestations of which motivated the decision to engage in a substantial change and shaped the object of the initiative. It illuminates t...

Video games are not just an important cultural artifact of youth culture but have considerable cognitive worth. Centered within an information processing theory and mediating processes’ framework, the empirical qualitative study investigated, via stimulated recall methods, the thinking skills and strategies of five teenagers while playing an action-adventure video game. Sixteen types and 600 in...

bone scanning using the 99mtc-phosphate analogs is an established diagnostic modality and a commonly requested radioisotope examination for a variety of pathologies involving the skeleton, such as osteomyelitis, bony metastases, and occult fractures. the bone scan is one of the most commonly requested procedure in most nuclear medicine department. the images show areas of increased and decrease...

Introduction: Cone beam computed tomography (CBCT) was introduced and became more common based on its low cost, fast image procedure rate and low radiation dose compared to CT. This imaging modality improved diagnostic and treatment-planning procedures by providing three-dimensional information with greatly reduced level of radiation dose compared to 2D dental imaging modalitie...

Introduction In CT imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. In order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. Materials and Methods The presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...

Background: The electrocardiogram artifact is a major contamination in the electromyogram signals when electromyogram signal is recorded from upper trunk muscles and because of that the contaminated electromyogram is not useful.Objective: Removing electrocardiogram contamination from electromyogram signals.Methods: In this paper, the clean electromyogram signal, electrocardiogram artifact and e...
