A novel cationic hydrophobically associating comb polymer, containing poly(oxyethylene) chains in the back-bone, is described and investigated with respect to the aqueous solubility by cloud point measurements. Cloud points were investigated as a function of polymer charge, poly(oxyethylene) chain length and concentrations of added NaCl and could be interpreted in terms of the aqueous behavior of
Survivors from several concentration camps arrived in Sweden during the spring of 1945. The Ravensbrück archives, discussed here, contains more than 500 interviews with the survivors.
The Late Ordovician-Early Silurian succession in Jamtland includes the marine Kogsta Siltstone, which is unconformably overlain by the shallow-water Ede Quartzite that grades into the open-marine Berge Limestone. A Hirnantia shelly fauna dates the uppermost Kogsta Siltstone as Hirnantian, and shelly fossils indicate an Aeronian age for the Berge Limestone. Biostratigraphically highly diagnostic co
Tailbiting codes encoded by feedback convolutional encoders are studied. A condition for when tailbiting will work is given and it Is described how the encoder starting state can be obtained for feedback encoders in both controller and observer canonical forms. Finally, results from a search for systematic feedback encoders that encode tailbiting codes with good decoding bit error probabilities ar
Mast cells, visualized with toluidine blue staining and the Falck-Hillarp fluorescence technique, were mainly located around large blood vessels in the hilus region of the ovary in adult rats and in immature rats treated with PMSG. Histamine concentration in the rat ovary was significantly reduced after the LH surge in PMSG-treated animals, corresponding to a reduced number of ovarian mast cells.

Background: Severe or fatal complications attributable to gas embolus, major vascular injury, or visceral injury are rare but have been reported after blind access to the abdominal cavity in laparoscopy. The open access technique has been introduced with the aim to reduce these injuries. This report evaluates access-related complications with both blind and open access techniques in a teaching hos
Background: Asthma patients exhibit an increased rate of loss of lung function. Determinants to such decline are largely unknown and the modifying effect of steroid therapy is disputed. This cross-sectional study aimed to elucidate factors contributing to such decline and the possible modifying effect of steroid treatment. Methods: We analyzed determinants of lung function and airway hyperresponsi
Popular Abstract in Swedish Nollvisionen antagen av Sveriges riksdag fastlägger att ingen skall behöva dödas eller skadas svårt i trafiken i Sverige. Införande av detta begrepp förskjuter fokus från trafikolyckorna till konsekvenserna av trafikolyckorna och härmed skapas förutsättningar för ett paradigmskifte i trafiksäkerhetsarbetet. För att åstadkomma önskade förändringar är det nödvändigt och bThe over-arching objectives of this thesis were to formulate a method to describe the consequences of traffic casualties, and to explain the influence of different traffic engineering factors on these consequences for society and individuals over time. A more detailed objective was to examine whether available short-term indicators can be used to predict consequences in a long-term perspective. Ot
Combined real-time ultrasound and pulsed Doppler ultrasound examinations were performed in 67 patients with third trimester hemorrhage and other symptoms related to placental abruption, starting from the onset of symptoms to delivery. In 52 of the cases, placental morphology was investigated by light microscopy. Thirteen patients were ultimately given the diagnosis abruptio placentae. None of the
In the present study the incidence of reflux, stricture formation and changes in glomerular filtration rate in patients with the submucosal tunnel or the Camey-Le Duc technique of ureteric implantation into the caecum/detubularized right colon used for continent cutaneous diversion/orthotopic bladder substitution was investigated. Reflux was found in two renal units and ureterointestinal stenosis
Gaps 10 mm wide in the sciatic nerves of 64 rats were bridged by bioartificial nerve grafts consisting of a silicone tube containing seven longitudinally placed filaments made of non-absorbable, (polyamide [Ethilon]) or absorbable, material (polydioxanone [PDS], polyglactin [Vicryl], and catgut). The purpose was to study the organisation of axonal growth inside the tube along such filaments. After
Psychological theories have traditionally assumed that moral judgment is caused by a reasoning process. This idea was challenged in two experiments. In the first participants were asked to make judgments in tasks set up to produce a conflict between intuition and reason. In the second, participants made judgments of morally questionable actions that were described either in a vividly disgusting wa
Concentrations of ammonia in air and ammonium in surface water were measured from a platform in the Southern North Sea close to the Dutch coast. Fluxes were derived from the measurements applying Monin–Obukhov similarity theory and exchange velocities calculated. The fluxes and air concentrations of ammonia were compared to results obtained from the Lagrangian transport-chemistry model ACDEP with
