Effects of Safety Measures for Pedestrians and Cyclists at Crossing Facilities on Arterial Roads

The principal aims of this thesis are to define suitable measures for safer pedestrian and cycle crossings on arterial roads, to implement these measures on a large scale and to acquire an insight into their effects on road users' safety, experiences, mobility and the environment, by creating a 30 km/h milieu at the above crossings. Two characteristically different types of measures, physical meas

Baryon number violation and string topologies

In supersymmetric scenarios with broken R-parity, baryon number violating sparticle decays become possible. In order to search for such decays, a good understanding of expected event properties is essential. We here develop a complete framework that allows detailed studies. Special attention is given to the hadronization phase, wherein the baryon number violating vertex is associated with the appe

What keystroke-logging can reveal about writing

Writing is a dynamic activity. In order fully to appreciate that fact, we have to analyse writing as it unfolds in teal time. The present paper gives a bird's eye perspective on the budding paradigm of using keystroke logging as a window on the online process of writing. First, methods and tools for designing writing experiments, recording writing activity, and for analysing recordings of writing

Effects of solar radiation on the abiotic and bacterially mediated carbon flux in aquatic ecosystems

Popular Abstract in Swedish Solljusets effekter på abiotiska och bakteriella kolflöden i akvatiska system I denna avhandling behandlar jag solljusets effekter på organiskt material. Jag har analyserat hur solljus förändrar olika sorters löst organiskt kol och partikulärt organiskt kol. Vidare har jag utvärderat de indirekta effekterna som förändringar av löst organiskt kol har på bakterier. SlutlIn this Thesis, I studied some of the current aspects of organic matter photochemistry. I analyzed abiotic phototransformations of several types of dissolved (DOM) and particulate organic matter (POM). I also evaluated the effects of phototransformation of several types of DOM on bacteria. Finally, in a field experiment, I analyzed net effects of solar radiation on organic matter decomposition. DO

High proteinuria selectivity index based upon IgM is a strong predictor of poor renal survival in glomerular diseases

BACKGROUND: The transport of large proteins across the glomerular capillary wall (GCW) may increase several fold in glomerular diseases. The occurrence of IgM in urine is a consequence of the presence of large defects or shunts in the GCW, whereas albuminuria is probably a result of an altered charge- and size-selectivity of the GCW. In order to examine whether patho-morphological differences infl

Weyl product algebras and modulation spaces

We discuss algebraic properties of the Weyl product acting on modulation spaces. For a certain class of weight functions omega we prove that M-(omega)(p,q) is an algebra under the Weyl product if p epsilon [1, infinity] and 1

The effect of packaging material on the sensory properties of broccoli.

Three different commercially available polymeric films were studied to determine their effect on the sensory properties of fresh broccoli (Brassica oleracea L. var. Italica cv. ‘Marathon’). The polymer materials investigated were oriented polypropylene (OPP), polyvinyl chloride (PVC) and one low density polyethylene (LDPE) which contained an ethylene absorber. The fresh broccoli was packaged and s

Behind the very notes: Playful creativity in coping with notation

This study explores musicians' ways of taking and giving meaning to notation in Western tonal music. From a socio-cultural theoretical perspective relations between traditions and individuals were especially accounted for. Linked to this perspective the method for the study was developed. Experienced pianists commented on well-prepared performances of one freely chosen work, and prescribed pieces

Evaluation of a NOx reduction system on an engine rig under stationary operation

The NOx storage and reduction approach was applied on a full-scale engine rig under stationary operation. NOx reduction experiments were performed and a catalyst model developed and tested. The exhaust system was equipped with a bypass system. A NOx reduction of 25-53% was achieved. At low temperature, higher values were reached when the exhaust gas bypass was longer than the injection period.
