Single-crystalline tungsten nanoparticles produced by thermal decomposition of tungsten hexacarbonyl

Nanometer-sized particles of W are of interest in semiconductor device research, where such particles may store electrons inside heteroepitaxially defined structures. In this paper, we present results concerning W particles produced by thermal decomposition of tungsten hexacarbonyl. By the described method, it was possible to produce size-selected, single-crystalline W particles in the size range

Non-uniform nanosecond gate-delay of hybrid pixel detectors

A simple experiment to characterize the gating properties of X-ray area detectors using pulsed X-ray sources is presented. For a number of time-resolved experiments the gating uniformity of area detectors is important. Relative gating delays between individual modules and readout chips of PILATUS2 series area X-ray detectors have been observed. For three modules of a PILATUS300K-W unit the maximum

Tissue variations of mosaic genome-wide paternal uniparental disomy and phenotype of multi-syndromal congenital hyperinsulinism

Mosaic genome-wide paternal uniparental disomy (GW-pUPD) is a rarely recognised disorder. The phenotypic manifestations of multilocus imprinting defects (MLIDs) remain unclear. We report of an apparently non-syndromic infant with severe congenital hyperinsulinism (CHI) and diffuse pancreatic labelling by 18F*-DOPA-PET/CT leading to near-total pancreatectomy. The histology was atypical with pronoun

Constraining terrestrial carbon fluxes through assimilation of SMOS products

The ongoing ESA funded'SMOS + Vegetation' project combines a retrieval component that aims at further improving the SMOS VOD product with an assimilation component that aims at demonstrating the added value of this product in constraining simulated land surface fluxes of carbon dioxide. This contribution focuses on the project's modelling and assimilation component. We describe the construction of

3-D Image-Based Dosimetry in Radionuclide Therapy

Radionuclide therapy is the use of radioactive drugs for internal radiotherapy, mainly for the treatment of metastatic disease. As opposed to systemic cancer therapies in general, the use of radioactively labeled drugs results not only in a targeted therapy but also the possibility of imaging the distribution of the drug during therapy. From such images, the absorbed doses delivered to tumors and

Dynamic Mapping of Diesel Engine through System Identification

From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur

The contact angle of nanofluids as thermophysical property

Droplet volume and temperature affect contact angle significantly. Phase change heat transfer processes of nanofluids – suspensions containing nanometre-sized particles – can only be modelled properly by understanding these effects. The approach proposed here considers the limiting contact angle of a droplet asymptotically approaching zero-volume as a thermophysical property to characterise nanofl

Molecular interactions between quinoa, the biocontrol agent Trichoderma and the pathogen Peronospora variabilis

Plants have developed complex molecular mechanisms to recognize and respond to the different microorganisms present in their surroundings. The most studied response mechanisms are plant defense responses. These defense response mechanisms share many similar components with the plant response mechanisms to beneficial microbes. Therefore, studying the defense response mechanisms against pathogens caPlants have developed complex molecular mechanisms to recognize and respond to the different microorganisms present in their surroundings.

Biogeochemical formation of calyx-shaped carbonate crystal fans in the subsurface of the Early Triassic seafloor

The Kuh e Dena sedimentary section in Iran developed on the southwestern margin of the Neotethys Ocean. The fossil- and bioturbation-lean Early Triassic section (Late Dienerian to Early Smithian) is typified by finely laminated calcareous shales that are interbedded with laterally extending carbonate beds, which are mostly composed of calyx-shaped carbonate crystal fans. The calyxes consist of fib

New Environmental Zones for Passenger Cars : Attitudes, Norms and Legal Compliance

The fundamental premise for the present report is to examine the degree to which it is possible to predict compliance with future rules regarding environmental zones for passenger cars. This project combines the main quantitative survey study (Sub-study 1) with a semi-systematic literature review that is first and foremost based in a qualitative, thematic analysis (Sub-study 2).The survey study is

User involvement in housing recovery : Cases from Haiyan affected areas in the Philippines

The aim of this study is to develop a better understanding of the relation between housing recovery and user involvement from a capability perspective. The thesis studies housing recovery in areas affected by typhoon Haiyan, which struck the Philippines on 8th November 2013. The focus is on three perspectives: a) approaches to housing reconstruction, b) explanation for unexpected housing outcomes,
