this study was an attempt to investigate the effect of teaching meta cognitive strategies on iranian intermediate efl students speaking proficiency. in this study the researcher has employed metacognitive strategies taken from brown (2000) to teach speaking strategies to number of participants. the participants were intermediate students of shokouh language institute; they were divided into an ...
A scale-up design procedure, based on a new physical mass transfer (PMT) model, whichdescribes the performance, for aerobic rotating biological contactors (RBC’s) is developed. This scale-up procedure can be used to determine the disc surface area needed to prevent an oxygen limitation or to obtain a specific degree of treatment. In contrast to the empirical, and most previous RBC performance m...
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
This study attempted to investigate the level of EFL learners’ epistemological beliefs and learning strategy use as well as the contribution of epistemological beliefs to their learning strategy use in Bahir Dar University. Comprehensively selected 136 EFL students at the Faculty of Humanities of Bahir Dar University responded to modified versions of Epistemological Beliefs Questionnaire and Mo...

Scale-up of micro- and milli-reactors: An overview of strategies, design principles and applications
Continuous-flow microreactor technology has been embraced by researchers in academia and industry due to its excellent transport properties the increased safety control over challenging chemical transformations. Despite popularity, scaling benefits associated with microenvironment proven be a daunting challenge. This review provides an up-to-date overview concerning different scale-up approache...
For the purpose of intensification an industrial-scale gas-liquid process, implementation in alternative reactor concept is investigated at Hamburg University Technology (TUHH) cooperation with Ehrfeld Mikrotechnik GmbH. Existing process operation data from a bubble column hint mass transfer limitation reaction. In project, jet loop (JLR) chosen to increase specific interfacial area between gas...
the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...
