computer-supported collaborative learning (cscl) is a new trend in educational sciences. this study investigates how knowledge sharing and transferring can be facilitated by using cscl in a problem-solving setting. intervention of research is education regarding sustainable water resources management (swrm) by computer-supported collaborative learning (cscl). the purpose of this research was to...

We evaluate the virial coefficients Bk for k ≤ 10 for hard spheres in dimensions D = 2, · · · , 8. Virial coefficients with k even are found to be negative when D ≥ 5. This provides strong evidence that the leading singularity for the virial series lies away from the positive real axis when D ≥ 5. Further analysis provides evidence that negative virial coefficients will be seen for some k > 10 ...

This paper gives a qualitative description how Young tableaux can be used to perform a Clebsch-Gordan decomposition of tensor products in SU(3) and how this can be generalized to SU(N).

This essay describes the development of groups used for the specification of symmetries from ordinary and magnetic point groups to Fedorov and magnetic space groups, as well as other varieties of groups useful in the study of symmetric objects. In particular, we consider the problem of some incorrectness in Vol. A of the International Tables for Crystallography. Some results of tensor calculus ...

We define a set of orthogonal functions on the complex projective space CPN−1, and compute their Clebsch-Gordan coefficients as well as a large class of 6–j symbols. We also provide all the needed formulae for the generation of high-temperature expansions for U(N)-invariant spin models defined on CPN−1.

introduction: collaborative testing is a learning strategy that provides students with the opportunity to learn and practice collaboration. this study aimed to determine the effect of collaborative testing on test performance and retention of course content in nursing students of shiraz university of medical sciences, shiraz, iran. methods: this quasi-experimental study was carried out on 84 st...
