Institutions' Role in Promoting a Competitive Market

This paper aims to examine whether competition law and policies have greater effect on competition when sound institutions are in place. Reports by major global actors as well as governmental reforming, show that there is unanimity on the notion that political reforming is essential in order to reach a more competitive market. Later economic research shows that institutions such as governance effe

RETRIEVING THE HEIGHT OF THE PLANETARY BOUNDARY LAYER OVER STOCKHOLM FROM LIDAR MEASUREMENTS

LIDAR-data från mätstationen Polly, som är en del av Arrhenius-laboratoriet och belägen på Stockholms universitets tak, används för att bestämning av planetära gränsskiktshöjden. För detta ändamål användes en stabil ”wavelet covariance transform” metod för analys av LIDAR-datasignalerna från åren 2011-2012. Endast molnfria dagar med högtrycks- förhållande är med i undersökningen för att minska mänLIDAR data from the Polly system on the roof of the Arrhenius laboratory at Stockholm University are used to determine the planetary boundary layers (PBL) height distribution. To this end, a wavelet covariance transform method is employed to analyze LIDAR measured data signals from the years 2011-2012. Only data with high pressure cloud free condition are used to reduce “bad” data. The main result

Direct estimates of C : N ratios of ectomycorrhizal mycelia collected from Norway spruce forest soils

Direct estimates of C:N ratios of ectomycorrhizal (EM) mycelia growing in situ in forest soils have been obtained for the first time. The mycelial samples were collected from sand-filled mesh bags that were buried in the soil and incubated for 12-18 months in two Norway spruce forests in southern Sweden. At harvest the mesh bags were heavily colonized and the mycelia were extracted from the sand w

Spectral characterisation of dairy products using photon time-of-flight spectroscopy

In this paper, we present, for the first time, the absorption and reduced scattering spectra of commercially available milk and yoghurt products, obtained using photon-time-of-flight spectroscopy. The ability of this technique to separate the contributions from absorption and scattering in the sample provides important information on the chemical composition and micro-structural properties, which

Reagentless Amperometric Biosensor For Nadh Detection

A sensitive and selective amperometric biosensor, based on NADH-oxidase (NADOx) working in tandem with horseradish peroxidase (HRP), which is electrically connected to graphite electrode via Os-redox polymer (RP), was developed. Two designs were considered for the biosensor optimization: (i) the first one, [G/HRP-NADOx], exploited the direct electron transfer between HRP and the graphite electrode

Correlations between polarisation states of W particles in the reaction e(-)e(+)-> W-W+ at LEP2 energies 189-209 GeV

In a study of the reaction e(-)e(+)-> W-W+ with the DELPHI detector, the probabilities of the two W particles occurring in the joint polarisation states transverse-transverse (T T), longitudinal-transverse plus transverse-longitudinal (LT) and longitudinal-longitudinal (LL) have been determined using the final states WW -> lvq (q) over bar (l = e, mu). The two-particle joint polarisation probabili

Temporary CO2 capture shut down: Implications on low pressure steam turbine design and efficiency

The Natural gas Combined Cycle (NGCC) with post combustion capture using liquid solvents may in some cases be of interest to design with a flexible steam bottoming cycle, so that it can operate both with and without CO2 capture. It is then important that the choice of the low pressure (LP) steam turbine exhaust size is made accordingly. The paper describes why a flexible NGCC requires a LP steam t

The relation between speed environment, age and injury outcome for bicyclists struck by a motorized vehicle - a comparison with pedestrians.

This study analyzes (a) the relation between injury severities, the age of the bicyclist and the speed environment at accident locations (mean travel speed of the traffic flow involved in the accident) where a bicyclist was struck by a motorized vehicle and (b) how these relations differ from those for struck pedestrians. Accident data from Sweden for the years 2004-2008 was used to identify accid

Optical Far-Field Method with Subwavelength Accuracy for the Determination of Nanostructure Dimensions in Large-Area Samples.

The physical, chemical, and biological properties of nanostructures depend strongly on their geometrical dimensions. Here we present a fast, noninvasive, simple-to-perform, purely optical method that is capable of characterizing nanostructure dimensions over large areas with an accuracy comparable to that of scanning electron microscopy. This far-field method is based on the analysis of unique fin

Nephrogenic systemic fibrosis and gadolinium-based contrast media: updated ESUR Contrast Medium Safety Committee guidelines

To update the guidelines of the Contrast Media Safety Committee (CMSC) of the European Society of Urogenital Radiology (ESUR) on nephrogenic systemic fibrosis and gadolinium-based contrast media. Topics reviewed include the history, clinical features and prevalence of nephrogenic systemic fibrosis and the current understanding of its pathophysiology. The risk factors for NSF are discussed and prop

Cancer risk in patients hospitalised for Graves' disease: a population-based cohort study in Sweden

BACKGROUND: The possibility of an association of Graves' disease (GD) with subsequent cancers raised by certain studies. METHODS: Using a database on 18 156 hospitalised GD patients, subsequent cancers were ascertained. RESULTS: Increased risks of thyroid and parathyroid tumours were limited to the early follow-up period, which is probably a surveillance bias. Cancer sites with observed excess inc

Moisture levels and drying potential of the concrete in Swedish reactor containments

The climatic conditions inside nuclear reactor containments are continuously monitored by the plant owners in order to e.g. maintain a suitable climate for the mechanical and electrical equipment. Due to the high temperatures, during operation, the concrete within the containment may act as a moisture source contributing to the humidity. To evaluate if, and to what extent, the concrete inside the

Daylight utilisation in perimeter office rooms at high latitudes: Investigation by computer simulation

A simulation study of daylight autonomy in perimeter office rooms at high latitudes is presented where the following variables are studied: Glazing-to-wall ratios (GWR), climate, orientation, inner surface reflectance, glazing visual transmittance, Venetian blind management and electric lighting dimming and switching systems. Based on daylight utilisation alone, the results indicate an optimal GWR
