Cloud Studies with the Droplet Aerosol Analyzer

Climate change and atmospheric aerosols are a threat for human health and life. Reducing aerosol emissions would save human lives close to the aerosol source, but could lead to more death due to the implications of a warmer climate. Aerosol particles acting as cloud or ice nuclei can induce a change in cloud properties and thus indirectly induce a change in planetary albedo, which is considered th

Phenyl beta-D-Galactopyranoside as an Acceptor Substrate for the Blood-Group H Gene-Associated Guanosine Diphosphate L-Fucose:beta-D-Galactosyl alpha-2-L-Fucosyltransferase

Phenyl β-d-galactopyranoside was found to be an efficient acceptor of l-[14C]fucose when guanosine diphosphate l-[14C]fucose was used as the donor substrate and human serum, submaxillary glands or stomach mucosa were the sources of l-fucosyltransferase. The enzyme utilising phenyl β-D-galactoside was present in the serum of donors of all ABO blood-groups examined, except those of the rare Oh (Bomb

Functional analysis of the alpha10beta1 integrin

Popular Abstract in Swedish Brosk är en speciell typ av vävnad, som bl.a. finns på våra ledytor, där det fungerar som ett stötdämpande och skyddande lager för benet. Broskets viktiga egenskaper framstår klart vid sjukdomar, som artros, där brosket på ledytor har förstörts och benet blottläggs, vilket resulterar i en permanent smärta. Brosk produceras av den enda celltyp som finns i broskvävnaden; The aim of this thesis was to study the function of the integrin a10b1. Integrins mediate signals between cells and their environment and regulate several cellular processes such as cell migration, proliferation and differentiation. The a10b1 integrin is expressed mainly by chondrocytes, the only cell type present in cartilage, and facilitates binding of the chondrocytes to the extracellular matri

Biodiversity in Agricultural Landscapes: Landscape and Scale-Dependent Effects of Organic Farming

Popular Abstract in Swedish Brukandet av jordbrukslandskapet har förändrats dramatisk under det senaste århundradet. Det tidigare mosaikartade landskapet, med en blandning av små åkrar, ängar, hagar och våtmarker, har idag i många områden ersatts av ett likformigt landskap som domineras av vidsträckta åkrar. Samtidigt har användandet av konstgödsel och kemiska bekämpningsmedel ökat. Tillsammans meDeclines in the distribution and abundance of many farmland species during recent decades have been attributed to agricultural intensification. Agri-environment schemes are commonly used in Europe to reduce this loss of farmland biodiversity, but their effectiveness may depend on several external factors. In this thesis, I have used one such scheme, organic faming, as a landscape scale experiment

Import and Export of Functional Mock-up Units in JModelica.org

Different simulation and modeling tools often use their own definition of how a model is represented and how model data is stored. Complications arise when trying to model parts in one tool and importing the resulting model in another tool or when trying to verify a result by using a different simulation tool. The Functional Mock-up Interface (FMI) is a standard to provide a unified model executio

Comparison of Ray Tracing and Channel-Sounder Measurements for Vehicular Communications

This paper presents the results of an accuracy study of a deterministic channel model for vehicle-to-vehicle (V2V) communications. Channel simulations obtained from the ray-tracing model developed by TU Braunschweig are compared to data gathered during the DRIVEWAY V2V channel measurement campaign at 5.6 GHz in the city of Lund in summer 2009. The analysis focuses on PDP and channel gains in an ur

Cervical Radiculopathy. Effects of Surgery, Physiotherapy or Cervical Collar. A prospective, randomised study.

Popular Abstract in Swedish Nervrotskompression i nacken - effekter av kirurgi, sjukgymnastik och halskrage. Under de senaste decennierna har besvär från halsrygg och axlar ökat hos befolkningen, medan besvär från ländrygg minskat. En orsak kan vara att tunga lyft i arbetet har minskat, medan sittande arbete med upprepade monotona armrörelser och arbete med framåtböjd nacke t.ex. framför datorskäThe efficacy of surgery, physiotherapy or a cervical collar in the treatment of chronic cervicobrachial pain of radicular origin was evaluated in a prospective, randomised study comprising 81 patients of both sexes, 28-64 years of age, referred for possible neurosurgical treatment. After neurological and radiological examination and giving their informed consent, they were randomised to one of the
