The purpose of the study was to investigate Finnish elementary and high school students' skills and practices of using the new information and communication technologies (ICT). Beliefs about the importance of ICT were also assessed. Five hundred and ®fteen students responded to a self-report questionnaire. The students attended 25 schools that used ICT intensively and represented all provinces ...

We study, in various special cases, total distributions on the product of a finite collection of finite probability spaces and, in particular, the question of when the probability distribution of each factor space is determined by the total

The word “researcher” is loaded and often confusing. It takes years to become one and to master all of its aspects. In this paper, we investigate whether or not this process of “becoming” can be catalyzed through education. The focus will be on wireless communications, though the same principle could very well be replicated to other disciplines.

The analog of Toupin's version of Saint-Venant's principle is proved for an isotropie, linear elastic mieropolar body of arbitrary length and of uniform cross-section which in the unstressed state is helical. That is, when such a body is loaded by self-equilibrated stresses and couple stresses at one end only, we show that the elastic strain energy stored in the part of the body beyond a certai...

Combining forms such as over-, underand ill-, as in overloaded, underpaid and ill-nourished show a similar distribution and pattern of behavior, and are thus likely to be amenable to a similar analisis, but since their syntax and semantics is slightly di erent from that of manner adverbs, we will not discuss them here. a degree reading and a \quality" reading in examples like (3a), but only a q...

Direct Displacement-Based Design (DDBD) is a performence-based seismic design method that has been proposed and well developed over the past two decades to design RC frame structures, shear walls and bridges. In this method, the behavior of a multi-degree-of-freedom (MDOF) sysytem is approximaeted by an equivalent single-degree-of-freedom (SDOF) substitute structure. Although this method has be...

alzheimer's disease (ad) is a progressive neurodegenerative disease characterized by memory and cognitive dysfunction due to neuronal cell loss in higher brain centers. senile plaques containing amyloid β (aβ) are associated with this disease as well as a reduction in cholinergic neuron numbers. tacrine is a reversible cholinesterase inhibitor in clinical use to treat moderate forms of ad. chit...

Individuals undergoing an unaccustomed exercise bout incorporating a high degree of eccentric muscle contractions commonly experience delayed onset muscle soreness. The damage manifests itself via tenderness, loss of strength, swelling, elevated muscle enzyme activity and loss of flexibility. Following an initial "damage bout," a repeated bout results in reduced symptoms. This protective effect...

background: in this feasibility study, a mechanically loaded in-vitro tissue culture model of joint morphogenesis using the isolated lower extremity of the 8 day old chick embryo was developed to assess the effects of mechanical loading on joint morphogenesis. methods: the developed in-vitro system allows controlled flexion and extension of the chick embryonic knee with a range of motion of 20 ...

An 11-year-old castrated male rabbit presented with a subcutaneous mass in the right hind limb. The mass comprised solid and myxoid areas. Solid areas were characterized by a storiform or interlacing pattern of spindle cells, strap cells, multinucleated giant cells and round cells with eccentrically located nuclei, whereas the myxoid areas were composed predominantly of elongated fusiform cells...
