Investigation of Hydrogen Enriched Natural Gas Flames in a SGT-700/800 Burner Using OH PLIF and Chemiluminescence Imaging

The effect of hydrogen enrichment to natural gas flames was experimentally investigated at atmospheric pressure conditions using flame chemiluminescence imaging, planar laser-induced fluorescence of hydroxyl radicals (OH PLIF) and dynamic pressure monitoring. The experiments were performed using a 3rd generation dry low emission (DLE) burner used in both SGT-700 and SGT-800 industrial gas turbines

Plant Aquaporins: A study of expression, localization, specificity, and regulation

Popular Abstract in Swedish 2003 års Nobelpris i kemi gick till professor Peter Agre för upptäckten av aquaporinerna. Aquaporiner är proteiner som sitter i membran och bildar kanaler som tillåter vatten och andra små neutrala molekyler att passera genom membranet. Aquaporinerna utgör en mycket gammal och välkonserverad proteinfamilj som finns i alla levande organismer som hittills undersökts. VäxAquaporins, or Major Intrinsic Proteins (MIPs), are integral proteins that facilitate transport of water and other small neutral solutes across biological membranes. They belong to a well conserved and ancient family of proteins, present in all organisms ranging from bacteria to plants and humans. The aquaporin family in plants is large, indicating complex and regulated water transport within the

Verification of sheet metal forming simulation of advanced thin plate parts using a first order friction model

There is today a need of better prediction of part geometry regarding industrial products by simulations. There is a need for better prediction of material inflow, stresses and strains and final geometry. One way to solve this could be by using a more advanced friction model. Today a zero order friction model (Coulomb friction) is normally used. By using a friction model of higher order the fricti

Das Problem des Widerstandes in den evangelischen Kirchen Europas 1933–1945

Abstract in German Der Widerstand in den evangelischen Kirchen Europas 1933-1945 ist ein komplexes Problem. In vielen Kirchen wurde er gegen die nationalsozialistische Ideologie oder die deutsche Besetzung geleistet. Jedoch kann das Problem nicht auf den Widerstaned gegen den Nationalsozialismus begrenzt werden. Kirchlichen Widerstand gab es auch gegen den Sowjetkommunismus, wie in Estland und Let

Dynamics of Polymer Adsorption onto Solid Surfaces in Good Solvent

Adsorption dynamics of various types of uncharged homopolymers onto solid surfaces in good solvent have been studied by using a coarse grained bead-spring model. Brownian dynamics simulation has been used to examine the adsorption process for polymers released near an adsorbing surface, and Monte Carlo simulations have been employed to explore equilibrium properties of adsorbed polymers. Two diff

Numerical simulation of fluid flow and heat transfer in corrugated ducts

A numerical investigation has been carried Out for the turbulent fluid flow and heat transfer in periodic fully developed corrugated ducts. Three turbulence models are used in the calculation: the standard k - epsilon model, the Re-Normalized Group (RNG) k - epsilon model and a Reynolds Stress Model (RSM). The turbulent heat flux is modeled by the simple eddy diffusivity model (SED). The numerical

Turnus: An open-source design space exploration framework for dynamic stream programs

Although the research on the design of heterogeneous concurrent systems has a long and rich history, a unified design methodology and tool support have not emerged so far. Therefore, the creation of such systems remains a difficult, time-consuming and error-prone process. The absence of principled support for system evaluation and optimization at high level of abstraction makes the quality of the

Auschwitz, autenticitet, kunskap

This essay reflects on issues surrounding the remembrance and teaching of the Holocaust. It was commissioned by the project Living History and the Swedish Prime Minister's Office.

The Intensive Care Unit syndrome/delirium, patients' perspective and clinical signs

Popular Abstract in Swedish Patienternas perspektiv på att vara IVA patient i relation till IVA syndrom/delirium Att intensivvårdspatienter (IVA patienter) som vårdats med respirator inte minns sin tid på IVA är en myt. Det finns patienter som inte minns , men de flesta patienterna i avhandlingen minns från uppvaknandet och borttagandet av droger och respiratorn sin tid de närmaste dagarna däreftWhen a person becomes critically ill, injured and/or undergoes major surgery and requires intensive care, a complex dilemma can arise. The condition of the illness, the specific caring situation and the environment lead to significant changes and effects in the senses and perceptional abilities. Under these conditions some patients can develop symptoms of the Intensive Care Unit syndrome/delirium.

Free Volume and Mesopores in Polymer Nanocomposites

Popular Abstract in Swedish Den fria volymen i en polymer är kopplad till flera fundamentala fysikaliska egenskaper som till exempel densitet, viskositet och gas diffusivitet. De fysikaliska egenskaperna hos polymerer i närheten av, eller i kontakt med, en solid yta har visats vara väsentligt olika dess bulkegenskaper. De fysikaliska egenskaperna hos polymerer i närheten av, eller i kontakt med, yThe free volume in polymers is coupled to several important physical properties, such as density, viscosity and gas diffusivity. The physical properties of polymers close to a solid surface have been shown to be significantly perturbed as compared to their bulk state. The behavior of polymers close to surfaces comes into play within the field of polymer composites, where the properties of the inte

Who and how to rein China's industrial energy?

This paper aims to present and suggest, from a foreigner's angle, ways in which to better explain and understand the difficulties facing Chinese policy-makers and government agencies that seek to improve the sustainability of China's industrial development. In this context, improved energy efficiency in the industrial sector is crucial; constituting a central pillar for all such strategies. The pa
