This article presents the major findings from six regional analyses conducted within the framework of the European Web-edu project (http://www.nettskolen.com/in_english/webedusite/index.html). It analyses the experiences of European institutions with the Learning Management Systems that they have purchased or developed themselves. Data was collected from in-depth interviews with 113 European ex...

We report simultaneous multi-frequency observations of the blazar PG 1553+113, that were carried out in March-April 2008. Optical, X-ray, high-energy (HE: ≥ 100 MeV) γ-ray, and very-highenergy (VHE: ≥ 100 GeV) γ-ray data were obtained with the KVA, REM, RossiXTE/ASM, AGILE and MAGIC telescopes. This is the first simultaneous broad-band (i.e., HE+VHE) γ-ray observation of a blazar. The source sp...

Zhejiang provinces of China. The roots of this plant are used as a remedy for icterus and arthritis in Chinese folk medicine. Hitherto, no chemical constituents or bioactivities of this plant have been reported. In the course of our search for active components from this plant, three new phenolics, (1S,2R)-1-(4 -O-b -D-glucopyranosyl-3 -methoxyphenyl)-2(4 -hydroxy-3 -methoxyphenyl)-1,3-propaned...

Cancer of unknown primary (CUP) site is a clinical syndrome that includes many types of advanced cancers. Patients are considered to have CUP if no anatomical primary site is identified after clinical evaluation. As diagnostic techniques improve, the spectrum of patients with CUP continues to evolve. Patients with CUP are common. The exact incidence is unknown because many of these patients are...

The heaviest element identified chemically is Z=112. Using the gas-phase thermochromatography technique, its volatility, i.e., the adsorption enthalpy, ∆Hads, on gold plated detectors located along the chromatography column was investigated and compared to that of Hg [1]. Very recently, results of the first chemical studies on element 114 using the same technique were reported [2,3]. Both eleme...

1 There are many ways to incorporate a notion of time into process algebras in order to integrate functional design and performance analysis. One major research strand, stochastic process algebras, concentrates on the annotation of actions with exponentially distributed random variables. This paper presents a tool for the functional analysis and performance evaluation of complex systems based o...

We report the independent discovery of a new extrasolar transiting planet around OGLE-TR-113, a candidate star from the Optical Gravitational Lensing Experiment. Small radial-velocity variations have been detected based on observations conducted with the MIKE spectrograph on the Magellan I (Baade) telescope at the Las Campanas Observatory (Chile) during 2003. We have also carried out a light-cu...

Two deletion-substitution mutations of phage lambda, spi-113 and spi-274, are shown to remove about half of the rightward operator OR. Physiological studies show that spi-113 is still repressible. Thus, the 50 or so nucleotides of OR deleted in this mutant are not absolutely essential for repression. prm-116, which inactivates the promoter essential for the maintenance of lambda repressor synth...
