Interactivity in the classroom is reported to promote a more active learning environment, facilitate the building of learning communities, provide greater feedback for lecturers, and help student motivation. Various definitions of interactivity exist in the literature, alternately focusing on the participants, structure and technology. The PLS TXT UR Thoughts research project builds on existing...

The shift from derivational rules to representational constraints that characterizes much contemporary work in phonology calls for a serious reevaluation of the notion of Underlying Representation (UR). The reason is that the ability of constraints to apply "in parallel" systematically obviates the need for a derivation. The purpose of this paper is to argue, consistently with my (1994) Princip...

The next-to-leading order QCD corrections to the production of gluino pairs at the Tevatron are presented in this paper. Similar to the production of squark-antisquark pairs, the dependence of the cross section on the renormalization/factorization scale is reduced considerably by including the higher-order corrections. The cross section increases with respect to the lowest-order calculation whi...

The quantum theory of ur-objects proposed by C. F. von Weizsäcker has to be interpreted as a quantum theory of information. Ur-objects, or urs, are thought to be the simplest objects in quantum theory. Thus an ur is represented by a twodimensional Hilbert space with the universal symmetry group SU(2), and can only be characterized as one bit of potential information. In this sense it is not a s...

In this paper we consider the nonlinear wave equation problem utt −B ` ‖u‖0, ‖ur‖0 ́ (urr + 1 r ur) = f(r, t, u, ur), 0 < r < 1, 0 < t < T, ̨̨ lim r→0+ √ rur(r, t) ̨̨ <∞, ur(1, t) + hu(1, t) = 0, u(r, 0) = e u0(r), ut(r, 0) = e u1(r). To this problem, we associate a linear recursive scheme for which the existence of a local and unique weak solution is proved, in weighted Sobolev using standard compa...

The aim of this study was to evaluate complexes of L-ascorbyl palmitate (ASCP) and urea (UR). This evaluation involved differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), near-infrared spectroscopy (NIR), a solubility test, a 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging test, and a mushroom tyrosinase inhibition assay. Physico...
