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

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

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

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

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

Beyond indexicality in the semiotics of photography.

The aim of this chapter is to tenatively discuss a sociological perspective on the relations between man, value orientation, behavioral orientation and sustainable development. Sociologists often get questions about the stability and development of values and willingness to change behavior in a direction which is more favorable to the environment. There are lots of problems with such questions. Th

‘Safety pays’ is a phrase commonly used. But, when it comes to putting that concept into practice, very few are actually successful at it. Reasons given include: it is costly or it is a waste of time or it is not the main cause of failure. However the real problem is that there is not enough guidance as to how to improve safety performance on site. Traditional measurement approaches include accide

We present an application of Sparse Bayesian Learning to the task of semantic role labeling, and we demonstrate that this method produces smaller classifiers than the popular Support Vector approach. We describe the classification strategy and the features used by the classifier. In particular, the contribution of six parse tree path features is investigated.

In this paper we evaluate, by means of Extrinsic Information Transfer (EXIT) charts, an iterative receiver that has emerged as a promising candidate for non-coherent multi-user multi-antenna OFDM systems. The receiver performs parallel interference cancellation (followed by linear filtering) and channel estimation, using soft symbols obtained from a bank of single-user decoders. For the sake of co
