Lithium tetrahydridoboranate is among the materials with the highest hydrogen content and has great potential as a possible H-2-storage material, although, the release and uptake of H-2 is not fully understood. In this work, LiBH4 was studied by in situ synchrotron radiation powder X-ray diffraction (PXD) and solid state CP/MAS NNIR both at variable temperatures. This study revealed two new phases
This review assesses the contribution of occupational asbestos exposure to the occurrence of mesothelioma and lung cancer in Europe. Available information on national asbestos consumption, proportions of the population exposed, and exposure levels is summarized. Population-based studies from various European regions on occupational asbestos exposure, mesothelioma, and lung cancer are reviewed. Asb
The structure of the title compound, [ Au2Fe( C21H23NP)( C17H14P) Cl-2], displays the pseudo-linear [ P - Au - Cl = 175.4 ( 1) and 174.0 ( 1) degrees] two-coordinate geometry usually observed in gold( I) complexes. The Au - P bond distances are 2.237 ( 2) and 2.224 ( 2) angstrom and the Au - Cl distances are 2.271 ( 3) and 2.278 ( 2) angstrom. The bis( diphenylphosphino)ferrocenyl ligand links the
The effect of deletion of old edges in the preferential attachment model introduced by Barabasi and Alberti([1]) is studied. We consider a model where every edge is deleted after a time Delta. The resulting graph has only Delta edges and with a high probability (1 + c)Delta nodes for some positive c. However its structure don't resemble the structure of the former model even for large Delta. In pa
In spite of the continuous development of production systems work-related musculoskeletal disorders is still a large problem. One reason might be the difficulties in quantifying the ergonomic effects of interventions. In this paper ergonomic consequences of technical and organisational changes were quantified in a plant for producing slats for parquet flooring. Muscle activity, work postures and m
Popular Abstract in Swedish I fem autopsistudier undersöktes humana käkledspreparat med tomografi (skiktröntgen), makroskopiskt (inspektion) och mikroskopiskt för förekomst av degenerativa (nedbrytande) förändringar. Speciellt undersöktes förekomst av erosiva förändringar i benet samt förändringar i den förkalkade broskzonen (skiktet mellan mjukbrosk och ben). Det förkalkade brosket var i normalaIn five autopsy specimen studies human temporomandibular joints were investigated by conventional tomography, macroscopy, and microscopy for degenerative changes, in particular erosive hard-tissue changes.In the microscopical evaluation special attention was paid to the calcified cartilage. The calcified cartilage was outlined by a flat or gently undulating basophilic tidemark and an irregular os
The aim of this project was to investigate possible methods for the concentration of acid hydrolyzate obtained from hydrolyzing wood. A detailed study of concentration of sugar solution by reverse osmosis, RO, has been performed as well as a comparison with mechanical vapor recompression evaporation. The comparison has, in this specific case, shown that RO is currently more expensive. The result i
The aim of this study was to develop a model for the quantification of the occupant risk in residential fires. The model should make it possible to quantitatively evaluate which effect the presence of a residential sprinkler has on the fire development. Statistics on causes and outcomes of residential fires were used as background material for the model development. A literature review was carried
Aims: To identify workplace and individual risk factors for occupational contact allergy and dermatitis. Methods: A cross-sectional study was carried out at an international company producing wind turbine systems in Denmark. A cohort of 724 production workers at four facilities was highly exposed to epoxy resin as well as other chemicals. A screening questionnaire (participation rate 84.7%) was fo
In this paper, it is demonstrated that a single-receptor biosensor can be used to quantitatively determine each analyte in binary Mixtures LIS in multivariate data analysis tools based on the dynamic responses received from flow injection peaks. Mixtures with different concentrations of two phenolic compounds, catechol and 4-chlorophenol, were measured with a graphite electrode modified with tyros
The determination of elemental abundances plays an important role inunderstanding the atmospheric processes that lead to anomalies inspectra of chemically peculiar stars. Ongoing study of the HgMn star χ Lupi has defined much of the elemental abundance distribution but progress is dependent upon the availability and accuracy of the atomic data. Here we present experimentally determined wavelengths
Stabilisation of electrochemically deposited Prussian blue (PB) films on glassy carbon (GC) electrodes has been investigated and an enhancement in the stability of the PB films is reported if the electrodes are treated with tetrabutyl ammonium toluene-4-sulfonate (TTS) in the electrochemical activation step following the electrodeposition. A multi-enzyme PB based biosensor for sucrose detection wa
New trilobite discoveries from eight localities in Vastergotland, south-central Sweden, demonstrate that the middle Cambrian Ptychagnostus punctuosus and Goniagnostus nathorsti zones are present in most Lower Palaeozoic outcrop areas of Vastergotland, though as a thin and impersistent conglomeratic limestone, up to approximately 15 cm thick. These zones have not previously been recognised in Vaste
A number of CFD (Computational Fluid Dynamics) calculations were carried out to simulate the large scale room corner fire, which is an important scenario for the evaluation of the fire performance of the surface lining material. Considered are turbulent gas flows, turbulent combustion, radiation and heat conduction inside solid boundary. Heat transfer from flame and hot gas is calculated, with the
The purpose of the paper is to identify maternal drug use that may be associated with an increased risk for cardiac defects in the offspring. A case-control study was performed with cases (cardiovascular defects without known chromosome anomalies) being identified from three Swedish health registers (n = 5015) and controls being all infants born in Sweden during the period 1 July 1995-2001 (n = 57
PURPOSE: To evaluate patency and clinical outcome in patients treated with catheter-directed thrombolysis and stent placement for acute extensive thrombosis affecting the iliocaval segment. MATERIALS AND METHODS: During a 10-year period (1994-2005), 37 patients with 44 limbs (26 female, median age 31 years) with acute extensive venous thrombosis affecting the iliocaval segment were treated with ca
The aim of this work was to study the leaching of hazardous substances in additives and admixtures that are commonly contained in concrete. Time-dependent leaching has been analyzed for three types of metal containing concretes: with ordinary Portland cement (OPC), fly ash, and slag. The concretes had uniform leaching patterns, clearly above detection limits. The prolonged diffusion test of 1,700
