on the relationship between different discourse markers and information-gap and reasoning-gap tasks, and the effectiveness of input enhancement type of instruction on students acquisition of discourse markers.
abstract tasks nowadays are at the center of attention in sla research. task types is one of the critical issues in this regard, their effectiveness and suitability to any particular context, their characteristics and the result they yield are among some of these issues. on the other hand, discourse markers (dms) have been very much investigated and their effectiveness in conveying the meaning...

– We show that the specific heat of the superconductor MgB2 in zero field, for which significant non–BCS features have been reported, can be fitted, essentially within experimental error, over the entire range of temperature to Tc by a phenomenological two–gap model. The resulting gap parameters agree with previous determinations from band–structure calculations, and from various spectroscopic ...

متن کاملMagnetic response of noncentrosymmetric superconductor La2C3 : Effect of double-gap and spin-orbit interaction
The presence of spin-orbit (SO) interaction in a noncentrosymmetric superconductor, La2C3 (Tc ≃ 11 K) is demonstrated by muon spin rotation (μSR) in its normal state, where μSR spectra exhibit field-induced weak depolarization due to van Vleck-like local susceptibility. In the mixed state, muon spin relaxation due to inhomogeneity of internal field (σv) exhibits a field dependence that is chara...
متن کاملEvolution of two-gap behavior of the superconductor FeSe1-x.
The superfluid density, rho{s}, of the iron chalcogenide superconductor, FeSe1-x, was studied as a function of pressure by means of muon-spin rotation. The analysis of rho{s}(T) within the two-gap scheme reveals that the effect on both, the transition temperature T{c} and rho{s}(0), is entirely determined by the band(s) where the large superconducting gap develops, while the band(s) with the sm...
