Three series of hard/soft styrene-acrylic latex based systems with equivalent compositions were prepared either by blending of homopolymer latexes or by preparing structured latex particles having core shell (CS) or inverted core shell (ICS) morphologies. Transmission electron microscopy (TEM) was used to investigate the particle morphologies, which were correlated to the calculated fractional rad

Popular Abstract in Swedish Denna avhandling undersöker den operativa kärnan i räddningsinsatser. Vidare undersöker den effekten av olika åtgärder som används vid räddningsinsatser mot brand i byggnad, effekten av sådana åtgärder till följd av beslut som fattas av befäl samt effekten av att allokera resurser i tiden och rummet vid en räddningsinsats mot brand i byggnad. Avhandlingen drar slutsatseThe operational core of firefighting operations was examined. The effects of various firefighting procedures on the fire ground, their impact upon conditions on the fire ground in which decisions by commanding officers are made and the effects of allocating resources in time and space on the fire ground were explored. In addition, various approaches for modelling firefighting operations were discu

A method for the in situ modification of hollow fiber membranes used as sampling units for microdialysis probes is presented. The method consists of adsorption-coating, high-molecular-weight poly(ethylene imine), PEI, onto membranes, already fitted on microdialysis probes. Modification of membranes was designed to specifically explore the so-called Andrade effects and thus enhance the interaction

A tunable external-cavity Littrow diode laser, with an intracavity electro-optical crystal, which combines a large mode-hop-free tuning range with high tuning speeds and high tuning accuracy, has been designed. A mode-hop-free single-mode tuning range of 50 GHz at 793 nm with an output power of 60 mW and tuning speeds of 1.5 GHz/mus is demonstrated. The instantaneous linewidth is smaller than 300

The local well-posedness for a periodic nonlinear dispersive wave equation in compressible elastic rods is established. Blow-up of solutions in finite time is obtained, provided their initial data satisfy certain conditions. (C) 2003 Elsevier Inc. All rights reserved.

Aim The aim of this work was to estimate C sequestration rates in the organic matter layer in Swedish forests. Location The region encompassed the forested area (23 x 10(6) ha) of Sweden ranging from about 55degrees N to 69degrees N. Methods We used the concept of limit values to estimate recalcitrant litter remains, and combined it with amount of litter fall. Four groups of tree species were iden

Aim: To describe the epidemiology of idiopathic thrombocytopenic purpura (ITP) in the Nordic countries, to define clinical subgroups and to investigate factors predicting chronic disease. Methods: A prospective registration was done from 1998 to 2000, including all children with newly diagnosed ITP aged 0-14 y and at least one platelet count

We show that experimental data are in very good agreement with predictions from the string fragmentation model by Bowler and Morris. We present a physical interpretation and discuss the relation to results obtained from Perturbative QCD and Local Hadron Parton Duality (LPHD). We also present implications for Bp correlations and the possibility to use these as a tag to study CP violation in B decay

Our everyday appliances ranging from toys to vehicles, as well as the equipment used to manufacture them, contain an increasing number of embedded computers. Embedded software often implement functionality that is crucial for the operation of the device, resulting in a variety of timing requirements and resource utilization constraints to be fulfilled. Industrial competition and the ever increasin

As ascites is related to liver cirrhosis in 80% of the patients, the present therapeutic guidelines are focused on ascites in liver cirrhosis. A combination of spironolactone and furosemide is recommended as first line therapy in patients with mild to moderate ascites and is effective in 90% of patients. In patients with pronounced or tense ascites, first line treatment is total paracentesis with

OBJECTIVE: To determine the diagnostic value of metaiodobenzylguanidine (MIBG) scintigraphy compared with computed tomography (CT) for the localization of phaeochromocytomas in clinical practice. DESIGN: Retrospective comparison between MIBG scintigrams and CT for localization of phaeochromocytomas in all patients successively examined with MIBG scintigraphy in Malmo from 1984 until January 1997.

Hummingbird hawkmoths were tested for their preferences for different types of sugar. In triple choice tests, moths sucked for longer periods from sucrose than from fructose and glucose. Naive moths released in a large flight cage and monitored over 24 days, drank on average 137 mul sucrose, 67 mul fructose and 7 mul glucose daily. In an independent test, moths spent more time feeding from sucrose

Primary systemic vasculitis is associated with a high mortality if left untreated and it is essential to make the diagnosis before permanent organ damage has occurred. In this thesis the diagnostic and prognostic significance of anti-neutrophil cytoplasmic antibodies (ANCA) in systemic vasculitis is investigated. The clinical significance of a capture enzyme-linked immunosorbent assay (ELISA) bas
