Following Wenger (1998), discussion lists for inservice teachers are often considered as examples of communities of practice. Such lists have an important role in the professional communication of French teachers and exist for all secondary disciplinary fields. The increase of users for ten years indicates that this exchange medium can be an instrument for professional development. But, many di...

The GOR program for predicting protein secondary structure is extended to include triple correlation. A score system for a residue pair to be at certain conformation state is derived from the conditional weight matrix describing amino acid frequencies at each position of a window flanking the pair under the condition for the pair to be at the fixed state. A program using this score system to pr...

Global brightness temperature observations of TOPEX/Poseidon microwave radiometer (TMR) at 18, 21, and 37 GHz have been collocated with near-simultaneous SeaWinds wind vector data as well as with monthly sea surface temperature and salinity products. The combined data allow us to study the dependence of zenith-directed ocean surface emissivity, at each frequency, upon both wind speed and direct...

Triple graph grammars have been used to specify consistency maintenance between inter-dependent and evolving models at a high level of abstraction. On a lower level, consistency maintenance may be specified by a triple graph transformation system, which takes care of all operational details required for executing consistency maintenance operations. We present a case study from software configur...

A triangle in a triple system is a collection of three edges isomorphic to {123, 124, 345}. A triple system is triangle-free if it contains no three edges forming a triangle. It is tripartite if it has a vertex partition into three parts such that every edge has exactly one point in each part. It is easy to see that every tripartite triple system is triangle-free. We prove that almost all trian...

We use geometrical arguments based on grain boundary symmetries to introduce crystalline interfacial energies for interfaces in polycrystalline thin lms with a cubic lattice. These crystalline energies are incorporated into a multi{phase eld model. Our aim is to apply the multi{phase eld method to describe the evolution of faceted grain boundary triple junctions in epitaxially growing microstru...

We characterize all equivariant odd spectral triples on the quantum SU(2) group having a nontrivial Chern character. It is shown that the dimension of an equivariant spectral triple is at least three, and there does exist a 3-summable equivariant spectral triple. We also show that given any odd spectral triple, there is an odd equivariant spectral triple that induces the same element in K. AMS ...

Objective: Positive Parenting Program (Triple-P) is an approved method of parent training for reducing child behavioral problems. The present study aimed to evaluate the effectiveness of standard level of Triple-P in improving behavioral problems and core Attention Deficit Hyperactivity Disorder (ADHD) symptoms of preschool children diagnosed with ADHD.  Methods: The study was conducted on 94 ...

We determine a class of triple systems such that each must occur in a triple system with uncountable chromatic number that omits T0 (the system consisting of two triples on four vertices). This class contains all odd circuit of length ≥ 7. We also show that consistently there are two finite triple systems such that they can separately be omitted by uncountably chromatic triple systems but not b...
