efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
The purpose of this research was to evaluate the effects of different levels of dietary protected butyric acid (PBA) on growth performance, blood metabolites, calcium and phosphorous of tibia in broilers. Two hundred and seventy day old Ross 308 male broilers divided in 9 treatments and 3 replicates (10 chicks per replicates), in a completely randomized design. Experimental treatments included:...
Interest in hurricane risk usually focuses on landfalling events of the highest intensity, which cause a disproportionate amount of hurricane-related damage. Yet assessing the long-term risk of the most intense landfalling events is problematic because there are comparatively few of them in the historical record. For this reason, return periods of the most intense storms are usually estimated b...
Motivated by recent developments in the computation of periods for string compactifications with c = 9, we develop a complementary method which also produces a convenient basis for related calculations. The models are realized as Calabi-Yau hypersurfaces in weighted projective spaces of dimension four or as Landau-Ginzburg vacua. The calculation reproduces known results and also allows a treatm...
asymmetric polyethersulfone (pes) microfiltration flat sheet membranes were composed by the phase inversion method (pim) and were used as supports. composite membranes were fabricated by coating silicone rubber as selective layer. effect of different concentrations of pes and pdms and different solvent such as nmp, dmf and dms effects as pes solvents and support thickness and different coagulat...
This paper introduces a text-based chat system designed to support conversations anchored to specific locations of shared images and reports our experience in operating it at WISS2004. Our system is unique in that it focuses on supporting communications scattered around among multiple images, while other systems for anchored conversations are designed for deeper discussions within a single docu...
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
