Collecting dialect data and making use of them an interim report from Swedia 2000

This paper consists of two, somewhat disparate parts. In the first part, some experiences of two years of fieldwork are summarized, concentrating, as the subtitle suggests, on the very heart of phonetic fieldwork: the encounters and interviews with the informants. As a result of the fieldwork, the project now has access to recordings from approximately 1300 speakers of more than 100 dialects of Sw

Simulation of Fully Developed Laminar Heat and Mass Transfer in Fuel Cell Ducts with Different Cross Sections

The fully developed laminar flow and heat transfer for ducts with rectangular and trapezoidal cross section in fuel cells have been numerically simulated with one porous wall with a uniform mass injection or suction, while the other three walls being impermeable. The new concept of thermal boundary conditions of combined constant heat flux and constant temperature on the walls was implemented. Bas

Polymer Bound Water-Soluble Metal Phosphine Complexes-Preparation, Characterisation and Catalytic Application

Popular Abstract in Swedish En ny typ av vattenlösliga fosfin ligander har utvecklats. Dessa fosfiner har använts som ligander i rhodium katalyserade tvåfasreaktioner.Komplexbildningen mellan de nya liganderna och olika metalcentra har studerats och de nya komplexen har använts i hydroformylerings- och hydreringsreaktioner. Polymerbundna kirala fosfiner har använts i enantioselektiv hydrering.Four new water-soluble phosphines have been prepared by utilising water-soluble polymers as charge carrying units. Coupling of methyl-4-(diphenylphosphino)-benzyl-amine or 4-diphenylphosphino benzaldehyde to poly-acrylic acid and poly-ethylene imine, respectively, afford the ligands PAA-PNH and PEI-PNH. Coupling of (2S,4S)-4-diphenylphosphino-2-di-phenylphosphino-methylpyrrolidine (PPM) or (R,R)-3

Some Results on Distinguishing Attacks on Stream Ciphers

Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. The thesis provides a general introduction to cryptology, explains the basic concepts, gives an overview of various cryptographic primitives and discusses a number of di

Småbarnsskolan: vad hände och varför?: en sekellång historia studerad med fokus på förändring av pedagogisk verksamhet från 1833 och framåt

Popular Abstract in Swedish Småbarnsskolan. Vad hände och varför? En sekellång historia studerad med fokus på förändring av pedagogisk verksamhet från 1833 och framåt. I denna bok tecknas en bild av småbarnsskolan som pedagogisk företeelse i Sverige. Den första småbarnsskolan inrättades 1833 och i kölvattnet följde ett trettiotal. Flera småbarnsskolor överlevde sekelskiftet och behöll sina beteckSome fields in the research about the history of childcare in the nineteenth century in Sweden is lacking. In popular textbooks infant schools (småbarnsskolor) are thought of and described as a pedagogical and social activity, while a later phenomenon, the nursery schools, seemed to lack all pedagogical insight, care-taking was exclusively at hand. I have questioned this dichotomy. What happened t

PBL för 100 studenter. Problem och möjligheter

Abstract in Undetermined Särskilt när en kurs läses av många studenter är en fungerande kommunikation mellan studenter och lärare väsentlig. PBL-metoden är i sig ett sätt att etablera en tvåvägskommunikation genom att låta studenterna komma till tals. Vi diskuterar några av de problem vi mött när en kurs har utvecklats från valfri med relativ få studenter till obligatorisk kurs för ett hundratal,

Single electron pumping in InAs nanowire double quantum dots

Closely spaced local gate electrodes are used to electrically define a double quantum dot along an InAs nanowire crystal. By applying a periodic pulse sequence to two plunger gate electrodes controlling the double quantum dot charge configuration, the device is operated as a single electron pump. The authors find that within measurement accuracy, the pumping current equals one electron per cycle f

Measurement-based modeling of vehicle-to-vehicle MIMO channels

Vehicle-to-vehicle (VTV) communications are of interest for applications within traffic safety and congestion avoidance, but the development of suitable communications systems requires accurate models for the VTV propagation channel. This paper presents a new wideband MIMO (multipleinput- multiple-output) channel model for VTV channels based on extensive MIMO channel measurements performed at 5.2

The use of ScCO2 for the extraction of LPS from S. enterica subsp. PCM 2266

The paper describes a novel extraction procedure for lipopolysaccharides (LPS) from Salmonella enterica subsp. enterica (PCM 2266). Process parameters for the extraction of LPS from bacterial mass were optimized by carrying out a two-level fractional design experiment. Four parameters, namely temperature, CO, flow rate, pressure and co-solvent composition were analyzed. The best crude extract yiel

Research Library Statistics: For Whom and for What Purpose? The Statistics Users' Views and Wishes

The paper reports a project conducted within the framework of the National Library of Sweden's Expert Group on Library Statistics. The project is financed by the National Library of Sweden, and it aims to capture how library managements make use of the current library statistics (based on the ISO-standard) in the decision-making process. Questions are also asked about the quality and usefulness of
