the extent to which written corrective feedback on linguistic errors can play a role in helping l2 writers improve the accuracy of their writing continues to be an issue of interest to researchers and teachers since truscott (1996) mounted a case for its abolition. while there is growing empirical evidence that written corrective feedback can successfully target some types of linguistic error (...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis , a one- way anova experimental design was carried out. 24 senior student of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inte...

today hydrogels are considered as the materials that are able to play important role in drug delivery systems. to design an effective hydrogel applicable network, mathematical modeling has a critical role. a successful drug delivery device relies not only on intelligent network design but also on accurate prior mathematical modeling of drug release profiles. in this study, the modeling of the i...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Cognition does not only depend on bottom-up sensor feature abstraction, but also relies on contextual information being passed top-down. Context is higher level information that helps to predict belief states at lower levels. The main contribution of this paper is to provide a formalisation of perceptual context and its integration into a new process model for cognitive hierarchies. Several sim...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
Tomorrow’s architectural practitioners seemingly need to gain an overview of, if not master, a wide range of computer aided architectural design applications, from image making to Building Information Modelling (BIM) to digital fabrication. However, we are sceptical whether there is wide recognition that there is value in a broader appreciation of the underlying principles that organize these a...
In this paper, we study the network design problem with relays considering network survivability. This problem arises in telecommunications and logistic systems. The design problem involves selecting two edge-disjoint paths between source and destination node pairs and determining the location of the relays in the network to minimize the network cost. A constraint is imposed on the distance tha...
The surge of modern techniques to fabricate structured materials paired with our ever deeper understanding of complex forms ofmatter present uswith the opportunity tomake and study dramatically new forms of designed materials and structures. This movement is being fueled by recent and rapid developments in a variety of fields, including soft matter, materials science, computer assisted design a...
