Popular Abstract in Swedish Dagens samhälle är mycket beroende av fordonsbränslen och kemikalier som producerats av råolja. Framtidens tillgång på råolja är oviss, det enda som är säkert är att det är en ändlig resurs. Användningen av olja bidrar dessutom till koldioxidutsläpp till atmosfären. För att säkra framtida tillförsel av energi och kemikalier till samhället och för att uppnå ett mer klimaMany scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. This interest has been enhanced by concerns about energy security and about the climate change caused by emissions of carbon dioxide. The result has been incre

[1] Vigorous debate still surrounds the cloud electrification process and unexplained regional variations in lightning activity. Here, we show that climatological maxima in lightning activity are associated with small effective diameter D-e of ice crystals near cumulonimbus cloud tops. This relationship, unlike lightning's more well-known relationship with cloud top height, is consistent over land

Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. To study the catalytic oxidation of CO, we have synthesised model CuO_x/CeO₂ cata

Popular Abstract in Swedish För datorbaserade konstruktionsanalyser används traditionella CAE-verktyg såsom finita elementmetoden (FEM) inom strukturanalys, datorbaserad strömningsanalys och stelkroppsdynamik. Behovet av predikteringar i produktutveckling och konstruktion utgår ifrån det faktum att man i början av utvecklingsprocessen har liten eller ingen kunskap om den blivande produktens egenskThe rapid development of computer-based design analysis tools and methods such as the finite element method (FEM) within computational structural mechanics (CSM), computational fluid dynamics (CFD), and multi-body systems (MBS) during recent decades has fundamentally changed the way in which products are designed and developed. Among the many advantages observed in industrial practice, one can men

Vectoring is a vital component of wideband wire- line communication systems. A disorderly leaving event (DLE) disturbs the vectoring operation since the precoder, which was designed for the channel before the change, is no longer up to date. Measurements indicate that the impact of a DLE can be serious for frequencies beyond 30 MHz, which corresponds to the band used by emerging wideband communica

Light is both the energy source and the dominant signalling input for photosynthetic organisms. Accordingly, up to 30–50% of the genes expressed in plant leaves are directly or indirectly regulated by light, and virtually all aspects of plant metabolism support photosynthesis, depend upon the products of photosynthesis or are affected by photosynthesis-related changes in metabolite levels. Though

Proton motions in hydrated proton conducting perovskites BaZr(0.90)A(0.10)O(2.95) (A = Y and Sc) have been investigated using quasielastic neutron scattering. The results reveal a localized motion on the ps time scale and with an activation energy of similar to 10-30 meV, in both materials. The temperature dependence of the total mean square displacement of the protons shows an onset of this motio

Popular Abstract in Swedish I ett väderälskande land som Sverige finns det väl ingen som inte är bekant med den väderkarta som ger oss information om hur prognosen för den närmaste tiden ser ut? Många av oss tittar dagligen på väderrapporten och låter den hjälpa oss att bestämma om vi ska cykla eller ta bussen, sätta på grillen eller laga mat i ugnen. Genom enkla visualiseringar i form av sol, regWith the aid of modern computer technology the application of visualization and simulation technology has become increasingly important in today’s society. Through computer modelling it is possible to experience, understand and explore environments, systems or objects in two or three dimensions and to see, hear and sometimes tangibly feel them. It may be environments or objects that do not yet exi

Aqueous solutions of a particular type of the nonionic cellulose derivative ethyl(hydroxyethyl)cellulose (EHEC) may form thermoreversible gels in the presence of ionic surfactants. Low-viscous solutions can be transformed to clear, stiff gels as the temperature is increased. The gelation may occur at temperatures as low as 30-35 °C which could make the systems interesting for applications, e.g. as

The copolymer of N-isopropylacrylamide (NIPAM) and methacryloyl derivative of spirobenzopyran (MSBP) with a molecular weight of 21 000 g/mol and the average molar MSBP content of 1.9% was prepared by free radical polymerization. The copolymer displayed its phase transition in water in the temperature range of 30-50 degreesC. UV irradiation of its aqueous solution caused photoinduced transformation

Economic sanctions are defined as the exercise of pressure by one state to produce a change in the political behaviour of another state. Traditional economic sanctions are directed at the entire population of a state whilst targeted sanctions are directed at a state’s individuals. This thesis discusses the application of economic sanctions against Iran by the UN, the EU and the United States. Econ

My thesis consists of three main parts. The first part, Chapter 2, describes the legal framework regulating free movement of goods, with the focus on quantitative restrictions in the EC. The starting point of this chapter is the current approach to harmonization in completing the internal market. This section considers the limits of economic integration prior to 1986 and the important steps taken

Aluminum matrix fly ash (AMFA) cenosphere composites were fabricated using the stir casting technique. The used type of fly ash cenosphere, which accounted for over 60% in all fly ash particles, was in narrow and small size (2-30 μm). During synthesis, effects of several key technological parameters on microstructure and properties were investigated using orthogonal experimental design. The optima

An experimental test system including the oil circulation system and the gas circuit system has been designed and built to explore the effects of the lubricating oil flow rate on the performance of a single-screw compressor, used in a portable natural gas liquefaction process. Outlet pressure, outlet volumetric flow rate, volumetric efficiency, and specific power rate are the parameters for evalua

In agro-ecosystems, environmental monitoring is fundamental to detect and survey changes related to land use change and management practices. Butterflies and moths have often been suggested as suitable indicators for monitoring environmental effects on biodiversity in farmlands. Here, we estimated the required sample size and monitoring effort necessary to run a Lepidoptera survey in European farm

Changes in extracellular levels of acetylcholine and choline in the hippocampal formation were measured using intracerebral microdialysis coupled to high performance liquid chromatography with post-column enzyme reaction and electrochemical detection. Various pharmacological and physiological manipulations were applied to awake unrestrained normal rats and rats subjected to a cholinergic denervati

The worldwide growing demand for whey proteins and derivatives requires more efficient and sustainable whey protein production processes. Whey is an important by-product from cheese manufacturing. In whey industry membrane processes such as microfiltration, ultrafiltration, nanofiltration and reverse osmosis are well-established to concentrate, fractionate and purify whey proteins as well as whey
