TiO2(B), a potential catalyst support, has been synthesized from a support precursor, K2Ti4O9. High resolution electron microscopy revealed that the 32% volume loss in this transformation is achieved by formation of facetted microvoids, around 10 nm in size, maintaining the morphology and size of the original crystals. A structural mechanism, including a hypothetical structure for a K2Ti 2O5 inter

Abstract This paper aims to gain a better understanding of the impact different micro-geometries has on stress distribution in cutting tools. Both principal and effective stress distribution are studied since these quantities have a major impact on the occurrence of damages in the cutting tool such as crack formation, flaking, chipping, breakage and plastic deformation. The development of a stagna

Homogenous charge compression ignition (HCCI) has been identified as a promising way to increase the efficiency of the spark-ignited engine, while maintaining low emissions. The challenge with HCCI combustion is excessive pressure rise rate, quantified here with Ringing Intensity. Turbocharging enables increased dilution of the charge and thus a reduction of the Ringing Intensity. The engine used

We report on an international collaboration, the FERRUM Project, whichaims at extending the database of experimental oscillator strengths foriron group elements and possibly evaluating theoretical andastrophysical data. The selection of individual projects is made withrespect to their relevance for abundance work and plasma diagnostics inastrophysics. In this paper we present recent measurements o

Embedded in the Western scientific rationality Hofstede’s methodological approach is constructed on a quantitative method characterized by a carefully selected sample of well educated white ‘men’ from the middle classes working for the same company and sharing similar occupation. The appointment of these men as the norm for national culture might mislead one to believe that Hofstede perceive of cu

This paper presents an analysis of the point-spread functions (PSFs),which may be expected in the so-called improved seeing limited mode forthe Euro50 (Extremely large telescope with a 50 m aperture). This modecomprises adaptive control of the deformable secondary mirror of theaplanatic Gregorian telescope configuration using guide stars in a widefield. I may result in efficient compensation of tu

Popular Abstract in Swedish Vid internationell handel med varor utgår olika skatter och avgifter; dessutom kan varorna vara föremål för import- och exportbegränsningar. Genom frihandelsavtal kan dock bestämmas att vissa varor får importeras och exporteras tullfritt. De bestämmelser som således gäller för olika varor sammanfattas för skilda varuslag i tulltaxan. Varuklassificeringen har därför storIn international commerce, various taxes and charges are levied on commodities; besides, goods may be subject to import and export restrictions. However, free-trade agreements may stipulate that some goods can be imported and exported free of charge. The regulations pertaining to different types of merchandise are reflected in the customs tariff of a state or customs union. The application of many

Max Liljefors, Art History and Visual Studies Technologization of Vision, Visualization of knowledge: The Role of “The Visual” in Conceptualizing ESS. ESS is popularly described as a gigantic microscope, which will use neutrons instead of ordinary light to let us see inside matter on the subatomic level. Other metaphors also foreground vision: “Seeing with neutron eyes”, and “Neutrons give the b

This thesis takes as its point of departure an elective course in English: 'Drama in Practice - Shakespeare on Stage'. The course combines theory and practice in that it contains (on the one hand) lectures and written work about one of Shakespeare’s comedies, and (on the other hand) an on-stage part with rehearsals of the same play, culminating in a performance, in costume, before an audience. The
