The influence of footwear insulation on foot skin temperature in the cold at low activity was investigated. Simultaneously, the thermal and pain sensations, and the influence of steel toe cap were studied. Eight subjects were exposed for 85 minutes to three environmental temperatures (+3; -12 and -25 °C) wearing 5 different boots. Insulation of footwear was determined with a thermal foot model. Th
Homogeneous Charge Compression Ignition (HCCI) holds great promises for good fuel economy and low emissions of NOdx and soot. The concept of HCCI is premixed combustion of a highly diluted mixture. The dilution limits the combustion temperature and thus prevents extensive NOdx production. Load is controlled by altering the quality of the charge, rather than the quantity. No throttling together wit
In wireless communications, stationary terminal scenarios are becoming increasingly important as bitrates goes up. Consequently, the need to improve the knowledge about the channel behavior and to develop realistic channel models for these scenarios is also increasing. The present work comprises both measurements and modeling of the radio channel when the terminal is stationary. The measurements w
Five to 15% of patients with primary sclerosing cholangitis (PSC) develop cholangiocarcinoma (CC) with a median survival of 5 to 7 months, an outcome not significantly improved by liver transplantation. However, if CC is found incidentally during the procedure or in the explanted liver, 5-year survival rates of 35% are reported. A noninvasive method to detect CC small enough to allow for intended
Popular Abstract in Swedish Kaféet är en mötesplats. Alla möten vilar på gränser - på gränser mellan de som möts, som umgänget frambringar. ”Kafékultur, kommunikation och gränser” är en studie av det sociala livet på kaféer, som utvecklar den socialpsykologiska innebörden av gränsen. Den kan ses som ett bidrag till förståelsen av vår tids informella och elementära sociala liv – intressant inte minThe café is a social meeting place. An as yet un-moulded aspect of social life is boundaries – how meetings rest on boundaries between participants that their intercourse brings forth. The aim of this dissertation is to study the café as a sociological and social–psychological phenomenon and at the same time contribute to forming the social–psychological aspect of boundaries. The study also contri
RATIONALE AND OBJECTIVES: This study was performed to document the perceived decrease in fatty involution at screening mammography during the past decade and evaluate the influence of hormone replacement therapy (HRT). MATERIALS AND METHODS: In December 1996, the mammograms of 261 consecutive screening patients with a comparison study obtained 5 years earlier were evaluated, and their breasts were
Transient absorption anisotropy of a polythiophene polymer in a thin film was studied on a femtosecond time scale. The anisotropy has a non-exponential decay on the sub-picosecond time scale, with a fastest component characterized by an ∼40 fs time constant. To simulate the anisotropy decay an incoherent energy migration model has been used. Comparison between the simulated and experimental kineti
Atrial fibrillation (AF), the most common atrial arrhythmia, has a complex aetiology and causes relevant morbidity and mortality due to different mechanisms, including but not limited to stroke, heart failure, and tachy- or bradyarrhythmia. Current therapeutic options (rate control, rhythm control, antithrombotic therapy, 'upstream therapy') only prevent a part of this burden of disease. Several n
Multiconfigurational SCF and second-order perturbation theory have been employed to study seven low-lying electronic states of the CoC molecule (X-2 Sigma(+), A(2)Delta, B(2)Phi, C(2)Phi, D(2)Pi, E(2)Pi, and F(2)Sigma(+)). Three doublet electronic states have been described for the first time: B 2 (D C(2)Phi (R-0 = 1.617 angstrom, To = 10455 cm(-1). and a), = 1159 cm(-1)), and D(2)Pi (R-0 = 1.632
The habitat distribution of red-listed plants, fungi and animals that have been found in the central parts of the parish of Stenbrohult, southern Sweden since 1970 is presented (Tables 1-4). In the centre of the 5 000 ha study area Carl Linnaeus was born in 1707, and he spent his summers there until 1727. In 1971-2002 at least 183 red-listed species have been found, with 73 wood-living beetle spec
High-spin states in Mo-86 were studied by means of the fusion evaporation reaction Ni-58(S-32,2p2n) Mo-86 at 135 MeV beam energy. Charged-particle-gamma gamma and -gamma gamma gamma coincidences recorded with the early implementation of the GAMMASPHERE array and the MICROBALL charged-particle detection system were used to largely extend the level scheme of the T-tau=1 nucleus Mo-86 to a possible s
In 91 patients (36 men, 55 women) who were hospitalized with symptoms of acute cholecystitis, cholescintigraphy was performed with 99m-Tc-ethyl-IDA, in order to evaluate the method in the diagnosis of acute inflammatory disease of the gallbladder. Five groups of patients were recognized: (A) abnormal scintigraphy and verified gallbladder disease, (B) abnormal scintigraphy without verified gallblad
