15 صفحه اولan investigation of the impact of self monitoring on langauge teachers motivational practice and its effect on learners motivation
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?...
Willmore–Chen branes and Hopf T-duality∗
We propose and study WCh-branes of M-theory and type IIA theory on backgrounds that are related by Hopf T-duality. The dynamics of these branes, with a reasonable degree of gauge symmetry, is reduced to that for particles that evolve somewhere along elastic worldlines. This constitutes an interesting holographic principle that allows us to determine moduli spaces of soliton solutions for WCh-br...
متن کاملAn inequality between Willmore functional and Weyl functional for submanifolds in space forms
Let φ : M → Rn+p(c) be an n-dimensional submanifold in an (n + p)dimensional space form Rn+p(c) with the induced metric g. Willmore functional of φ is W (φ) = ∫M (S − nH2)n/2dv, where S = ∑ α,i, j (h α i j ) 2 is the square of the length of the second fundamental form, H is the mean curvature of M . The Weyl functional of (M, g) is ν(g) = ∫M |Wg|n/2dv, where |Wg|2 = ∑ i, j,k,l W 2 i jkl and Wi ...
متن کاملAn approach to the Willmore conjecture
We highlight one of the methods developed in [6] to give partial answers to the Willmore conjecture, and discuss how it might be used to prove the complete conjecture. The Willmore conjecture, dating from around 1965, asserts that the integral of the square of the mean curvature H over a torus immersed in R3 (with the induced metric) should always be at least 2π2: W := ∫ T 2 H ≥ 2π. A weaker lo...
