K-12 education reform research suggests that new models of teacher professional development (TPD) are needed to establish and support communities of teachers engaged in school reform. We are working with several TPD organizations to develop a new on-line TPD community concept called TAPPED IN. Together, we are forging what we believe will be a self-sustaining TPD community in an on-line environ...

During the last few years, new synchronization techniques to send data between IC’s at increasingly high datarates have been developed. Some of them rely on digital delay lines. The timing accuracy of the delay lines is crucial for a good functionality of the synchronization mechanism. This paper will present a strategy to measure the tap-delays of a digital delay-line, using the well-known osc...

This report compares industrial state-of-the-art products (TTTech, DaVinci and dSPACE) for development of dependable real-time applications with the methodology introduced by Giotto and refined by the Timing Definition Language (TDL). Giotto/TDL aims at a paradigm shift in the development of dependable real-time control systems by focusing on the application rather than on the platform. It repr...

The main conclusion from this study is that C3 receptors are not required for the generation from B cells of a thymus-dependent 7S antibody response. The requirement for C3 receptors on the precursors of antibody-forming cells was studied in an adoptive transfer system using thoracic duct lymphocytes (TDL) from primed rats as a source of precursors and irradiated recipients as hosts. 7S precurs...

The origin of immunoglobulin on the surface of TDL in the rat has been studied by comparing the binding of purified alloantibodies recognizing the Ig-1a allotype of rat light chain, with that of rabbit antirat Fab antibodies. Both reagents labeled all TDL from rats of the DA strain (Ig-1a) with two categories of cells being detected; one binding 100-2,000 molecules of antibody, the other 10,000...

El Programa de Estimulación Lingüística Expresión Oral (PELEO) está orientado a la intervención del lenguaje para ser utilizado con niños Retraso Lenguaje (RL) y Trastorno Desarrollo (TDL). Su diseño, visual ágil, emplea láminas imágenes que se muestran los (basadas en bits inteligencia Doman). objetivo principal artículo es comprobar su eficacia niñas RL TDL tres seis años. La metodología una ...

The fluorescence activated cell sorter was used to determine the class of immunoglobulin on the thoracic duct lymphocytes (TDL) which carried IgG memory. Although only about 3% of all TDL carried membrane IgG these cells accounted for most, if not all, of the adoptive IgG anti-DNP response. It is concluded that both CR+ and CR- cells mediating IgG memory in rat TDL bear the same class of membra...

AIM In demyelinating disease spectrum, tumor-like (tumefactive) demyelinating lesions (TDL) are rarely seen. Atypical imaging and clinical features of these lesions may cause misdiagnosis of tumor or abscess. MATERIAL AND METHODS 25 patients with TDL in our center were followed and clinical, magnetic resonance imaging (MRI), magnetic resonance spectroscopy, cerebrospinal fluid (CSF) findings ...

This report introduces the notion of transparent distribution of real time software components. Transparent distribution means that (1) the functional and temporal behavior of a system is the same no matter where a component is executed, (2) the developer does not have to care about the differences of local versus distributed execution of components, and (3) the components can be developed inde...
