Dynamical Mean-Field Theory for Doped Antiferromagnets

We have generalized the dynamical mean-field theory to study the doping dependence of the crossover from antiferromagnetic to short-range order modeled by an incommensurate spin density wave in the Hubbard model. The local self-energy which includes spin fluctuations gives quasiparticle weights and spectral properties in good agreement with quantum Monte Carlo and exact diagonalization data in two

Teachers developing a Scholarship of Teaching and Learning at a Faculty of Medicine

Many universities are actively promoting scholarly inquiry into teaching and learning to improve education. Strategies used may involve support for development projects, teaching awards and academies. The Faculty of Medicine, Lund University, Sweden, has developed a Teaching Academy with criteria for membership founded in Scholarship of Teaching and Learning (Kreber, 2002; Trigwell & Shale, 20

Are We Promoting a Surface Approach to Learning During the First Year of Engineering Educations?

The legislated goals for Master of Science in Engineering educations include goals like having the ability to critically, independently and creatively identify, formulate and handle complex problems as well as participate in research and development work and thus contribute to knowledge development. One might therefore argue that these educations are required to promote a deep approach to learning

Comparison of two modeling approaches for a multi-cylinder paper dryer

Two modeling approaches for a multi-cylinder cardboard dryer were compared with respect to fitting parameters and model structure. Model 1 includes internal mass transfer while model 2 does not. One important fitting parameter for all models is the contact heat transfer coefficient between the cylinder and the paper. Two different correlations, a constant value and a moisture dependant (linear) he

African farm trajectories and the sub-continental food crisis

Abstract in UndeterminedAfrican agriculture is more dynamic than one would expect, given the chronic food crisis in the sub-continent. Due to macro-economic and political preconditions, however, farmers’ dynamism is channelled into other directions than would be required to attain self-sufficiency in food grains. This is the main conclusion of this study of farm dynamics in eight African countries
