Cape Dorset is a community on BaSn Island in Canada's Northwest Territories. An art co-operative the West Baffin Eskimo Co-operative (W.B.E.C.) was formed there in 1959 to encourage the production of drawings, prints, sculpture, and other handicrafts. The Co-operative purchases hundreds of drawings from artists annually and selects and translates some of these into prints for its yearly collect...

This paper outlines the components of a mobile education system and lists selected examples of universities employing m−education. Several possible approaches in designing and installing such a system are discussed. The main focus is on the project WELCOME (Wireless E−Learning and Communication Environ− ment) at the University of Regensburg. We argue that mobile/electronic education should not ...

7alpha-Methyl-19-nortestosterone (MENT) is a potent synthetic androgen that is resistant to 5alpha-reductases and therefore less prone to over-stimulate the prostate. It is a good candidate for implant administration in long-term androgen replacement therapy for hypogonadal men or as part of a male contraceptive system. To investigate the pharmacokinetics of MENT after i.m. administration, sing...

It is unquestionably essential for students to gather their previous knowledge of specific subjects when they are about to learn new and more complex ones. The gaps left by the absence of welldefined learning prerequisites not only contribute to the increase in the learning difficulties, but also lead many students to fail in school. This situation gets even more serious when students are not a...

Let R be an integral domain. Note some obvious facts. Every ele­ ment a of R divides 0. Indeed 0 = 0 · a. On the other hand, 0 only divides 0. Indeed if a = q · 0, then a = 0 (obvious!). Finally every unit u divides any other element a. Indeed if v ∈ R is the inverse of u, so that uv = 1 then a = a · 1 = (av)u. Lemma 19.3. Let R be an integral domain and let p ∈ R. Then p is prime if and only i...

An overview is given of different approaches to describing the process of deconfine-ment in quantum chromodynamics. The analysis of the known approaches demonstrates that the detailed picture of how deconfinement really occurs has not yet been understood. Therefore, one has to be rather cautious when interpreting experimental signals as attributed to deconfinement.
