the central purpose of this study was to conduct a case study about the role of self monitoring in teacher’s use of motivational strategies. furthermore it focused on how these strategies affected students’ motivational behavior. although many studies have been done to investigate teachers’ motivational strategies use (cheng & d?rnyei, 2007; d?rnyei & csizer, 1998; green, 2001, guilloteaux & d?...

Graphene is determined by a wonderful carrier transport property and high sensitivityat the surface of a single molecule, making them great as resources used in Nano electronic use.TGN is modeled in form of three honeycomb lattices with pairs of in-equivalent sites as {A1, B1},{A2, B2}, and {A3, B3} which are located in the top, center and bottom layers, respectively. Trilayer...

drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

Single file translocation of a homopolymer through an active channel under the presence of a driving force is studied using Langevin dynamics simulation. It is shown that a channel with sticky walls and oscillating width could lead to significantly more efficient translocation as compared to a static channel that has a width equal to the mean width of the oscillating pore. The gain in transloca...

Large-conductance Ca2(+)-activated K+ channels (BK) regulate action potential (AP) properties and excitability in many central neurons. However, the properties and functional roles of BK channels in parasympathetic cardiac motoneurons (PCMNs) in the nucleus ambiguus (NA) have not yet been well characterized. In this study, the tracer X-rhodamine-5 (and 6)-isothiocyanate (XRITC) was injected int...

In this study, a proton exchange membrane fuel cell operating at low temperatures with single channel is modeled. The prepared model has been compared experimental data and its accuracy proved. Using model, the impact of change width on performance height being constant geometry cross-sectional area was investigated. It found that enlargement where reactant contacts diffusion layer provides an ...

the intakes usually have been used in water distribution networks, irrigation channels, sewage networks, and the water/wastewater treatment facilities, etc. lack of sediment control entered to the intake channel is the main reason of entering sediments to the installation systems, which makes many problems for different parts. due to suspended particles in water, the facilities used such as pum...

The subjective attributes of 2-channel phantom images of transient piano, continuous trumpet and male speech sources were elicited using pair-wise comparison between reference mono images and their phantom images. The attributes elicited included ‘image focus’, ‘image width’, ‘image distance’, ‘brightness’, ‘hardness’ and ‘fullness’. The effect of interchannel time and intensity differences on ...
