By using a three dimensional computational method, gas flow and heat transfer have been investigated and analyzed for both cathode / anode ducts of proton exchange membrane fuel cells. The Brinkman- Forchheimer-extended Darcy model is employed to investigate the flow inside the porous layer of the duct. Effects of inertial coefficient, together with permeability, effective thermal conductivity, th

How human exposure levels of air pollutants are related to health status is an issue of great importance for e.g. infrastructural and urban planning. This study analysed the exposure levels of NO2 for individuals depending on their country of birth. The study was conducted within three different study areas of varying characteristics and extent to decide whether any such associations existed and i

This paper is a part of a research project studying human interaction with lighting control devices in public indoor environments. Factors such as the perception of the environment or objects may guide human behavior, therefore the perception of lighting related objects may have an impact on the behavior toward energy saving. This paper reports the development of a questionnaire for measuring hu

Objective To determine coverage and generalisability of data in the Swedish Biologics Register ARTIS. Methods Patients with adult onset rheumatoid arthritis (RA) were identified in the National Patient Register and the Swedish Rheumatology Quality Register, including the ARTIS cohort of patients exposed to biological agents. Exposure to etanercept and adalimumab between 2006 and 2008 was determine

The aim was to investigate whole-body and red marrow absorbed doses in treatments of neuroblastoma (NB) and adult neuroendocrine tumors (NETs) with (131)I-metaiodobenzylguanidine and to propose a simple method for determining the activity to administer when dosimetric data for the individual patient are not available.

New basis sets of the atomic natural orbital (ANO) type have been developed for the lanthanide atoms La-Lu. The ANOs have been obtained from the average density matrix of the ground and lowest excited states of the atom, the positive ions, and the atom in an electric field. Scalar relativistic effects are included through the use of a Douglas-Kroll-Hess Hamiltonian. Multiconfigurational wave funct

The effects of a driver assistance system for keeping safe speed and safe distance (referred to as SASPENCE) on driver behaviour, reactions and acceptance were evaluated in a test carried out in 2006. Twenty test drivers, recruited by ads, drove two times (once with the system off and once with the system on) in real traffic conditions along a 50 km long test route containing urban and rural roads
