A systematic approach to produce small courseware modules for combined learning and knowledge management environments

Combining technology enabled learning and knowledge management is a very promising strategy to systematic competence building in software organizations. In order to set-up a combined learning and knowledge management environment and to support organization members in packaging small chunks of knowledge into courseware modules, Fraunhofer IESE developed the IntView-KM methodology. IntView-KM define

Estimating northern peatland CO2 exchange from MODIS time series data

Studies using satellite sensor-derived data as input to models for CO2 exchange show promising results for closed forest stands. There is a need for extending this approach to other land cover types, in order to carry out large-scale monitoring of CO2 exchange. In this study, three years of eddy covariance data from two peatlands in Sweden were averaged for 16-day composite periods and related to

Regulation of the cytoskeleton and the adhesiveness of intestinal epithelial cells by leukotriene D4

Popular Abstract in Swedish Inflammationsreaktioner kan utlösas i alla vävnader som ett generellt svar på olika stimuli. En defekt eller utebliven reaktion kan leda till svåra infektion sjukdomar. De olika stimuli som startar den inflammatoriska processen frisätter olika inflammationsmediatorer i vävnaden. Dessa kan vara lagrade i celler och frisätts till omgivningen. Vad gäller arachidonsyra prodLeukotrienes belong to a family of biologically active conjugated trienes that are formed from arachidonic acid via the 5-lipoxygenase pathway and are important mediators of inflammatory reactions. The CysLT1 receptor that specifically serves as receptor for leukotriene D4 (LTD4) has been identified as a G-protein coupled receptor. Cell-cell and cell-matrix complexes of epithelial cells are inter

Euclidean and Affine Structure/Motion for Uncalibrated Cameras from Affine Shape and Subsidiary Information

The paper deals with the structure-motion problem for uncalibrated cameras, in the case that subsidiary information is available, consisting, for example, in known coplanarities or parallelities among points in the scene, or known positions of some focal points (hand-eye calibration). Despite unknown camera calibrations, it is shown that in many instances the subsidiary information makes affine or

Characterization of Pt/γ-Al2O3 Catalysts Deactivated by Hexamethyldisiloxane

The deactivation of alumina supported platinum and iron catalysts by hexamethyldisiloxane (HMDS) exposure has been investigated. Three catalysts (Pt/Al2O3, Fe/Al2O3 and Fe/Pt/Al2O3) were prepared and the influence of short- and long-term deactivation on the activity for oxidation of ethyl acetate was studied. The catalysts were characterized using BET, ICP-AES, XPS, SEM and CO chemisorption. The d

Atom-atom correlations in colliding Bose-Einstein condensates

We analyze atom-atom correlations in the s-wave scattering halo of two colliding condensates. By developing a simple perturbative approach, we obtain explicit analytic results for the collinear (CL) and back-to-back (BB) correlations corresponding to realistic density profiles of the colliding condensates with interactions. The results in the short-time limit are in agreement with the first-princi

Computationally Efficient Robust Widely Linear Beamforming for Improper Non-Stationary Signals

In this work, we introduce a computationally efficient Kalman-filter based implementation of the robust widely linear (WL) minimum variance distortionless response (MVDR) beamformer. The beamformer is able to achieve the same performance as the recently derived robust WL MVDR beamformer, but avoids the computationally burdensome solution based on a second order cone programming (SOCP), and exploit

Utvärdering av ett interaktivt diagnostiskt prov för studentaktivering och kontinuerlig återkoppling i föreläsningskurser

Målsättningen med detta projekt var att utveckla ett praktiskt och resurssnålt pedagogiskt instrument för att öka den kontinuerliga återkopplingen och studentaktiveringen i stora föreläsningskurser. Ett interaktivt diagnostiskt prov utvecklades, och implementerades sedan i LTH-kursen Miljökemi med 88 studenter. Det anonyma flervalsprovet hade 12 frågor som studenterna fick svara på strax före en f
