Mercury is the only atmospheric pollutant that is present in the atmosphere in atomic form. The optical resonance line at 254 nm can be used for absorption measurements using different optical remote sensing techniques. Range-resolved Hg mapping can be performed using the differential absorption lidar (DIAL) technique. We have used the lidar technique both for mapping of industrial plumes and for

OBJECTIVES: This study examined whether long workhours in combination with an extended workweek (12 hours/7 days), as requested by the workers, impaired attention and cognitive performance and whether the degree of hypothalamic-pituitary-adrenal (HPA) activation was related to the response to the performance tasks. METHODS: A group of 41 male construction workers between 21 and 60 (mean 39) years

This paper suggests reasons why an organisation starts the process of reorganising software applications hosting and how these reasons are connected with resilience in software applications used and in business processes. The decision investigated is a sourcing decision process in a Swedish municipality. The main reason for starting the sourcing decision process was that the municipality needed to

PURPOSE: An inherent problem in breast cancer treatment is that current therapeutic approaches fail to specifically target the dissemination of breast cancer cells from the primary tumor. Clinical findings show that the loss of Wnt-5a protein expression in the primary breast tumor predicts a faster tumor spread, and in vitro analyses reveal that it does so by inhibiting tumor cell migration. There

BACKGROUND: To investigate the correlation between various orthopedic conditions and overweight/obesity at the Department of Orthopedics, Malmö University Hospital Sweden. Obesity is associated with numerous major medical conditions. Although the relationship between gonarthrosis and osteoarthritis and body mass index (BMI) is well recognized, other orthopedic conditions have been less well studie

Sequential Monte Carlo (SMC) methods have demonstrated a strong potential for inference on the state variables in Bayesian dynamic models. In this context, it is also often needed to calibrate model parameters. To do so, we consider block maximum likelihood estimation based either on EM (Expectation-Maximization) or gradient methods. In this approach, the key ingredient is the computation of smoot

Laser-induced fluorescence (LIF) for in vivo point monitoring and fluorescence microscopy incorporating a CCD camera were used to study the fluorescence distribution of 5-aminolevulinic acid (ALA)-induced protoporphyrin IX (PpIX) in tumours. Fluorescence in a chemically induced adenocarcinoma in the liver of rats and in an aggressive basal cell carcinoma in a patient were studied after intravenous

The role of percutaneous renal tumour biopsy (RTB) remains controversial due to uncertainties regarding its diagnostic accuracy and safety.
