A biochemical oxygen demand (BOD) sensor, based on an immobilised mixed culture of microorganisms in combination with a dissolved oxygen electrode, has been developed for the purpose of on-line monitoring of the biological treatment process for waste and wastewater. The sensor was designed for easy replacement of the biomembrane, thereby making it suitable for short-term use. The drawbacks of acti
Wound healing that precedes scar formation may be unbalanced under pathological conditions leading to structural changes of the tissue. At the moment, the mechanisms behind this unbalance are unclear. When these changes occur in internal organs such as the lung, they may result in organ dysfunction with fatal consequences for the patient. This phenomenon is defined as airway remodeling, and occurs
Background. Around 25 million Caucasian women are carriers of the FV Leiden mutation that causes activated protein C (APC) resistance. This is a heritable condition with a lifelong increased risk of venous thromboembolism. We performed this study to investigate women's reactions to their awareness of being APC-resistant and the consequences of this awareness. Methods. All APC-resistant women (n =

A scheduling architecture for real-time control tasks is proposed. The scheduler uses feedback from execution-time measurements and feedforward from workload changes to adjust the sampling periods of the control tasks so that the combined performance of the controllers is optimized. The performance of each controller is described by a cost function. Based on the solution to the optimal resource al
BACKGROUND--Continuous epithelial shedding and restitution processes may characterise the airways in diseases such as asthma. Epithelial restitution involves several humoral and cellular mechanisms that may potentially be affected by inhaled anti-asthma drugs. The present study examines the effect of a topical steroid on epithelial restitution in vivo in the guinea pig. METHODS--The airway epithel
Popular Abstract in Swedish Hawaiianernas liv och historia har dokumenterats allt sedan första kontakten med västerländska äventyrsresanden i slutet av 1700-talet. I samband med amerikanska missionärers ankomst år 1820 introducerade och etablerade dessa missionärer en puritansk lära och kunskapsförmedling via det skrivna ordet. Mötena mellan de olika kulturerna har beskrivits som fredliga. Dock haThe life and history of the Hawaiians has been documented ever since the contact with Western adventurers at the end of the 18th century. In connection with the arrival of American missionaries in 1820, these missionaries introduced and established a puritanical doctrine and method of communicating knowledge by way of the written word. The encounters between the different cultures have been descri
Popular Abstract in Swedish Mixotrofa växtplankton i sjöar Vad är växtplankton? I hav och sjöar finns det mängder av mikroskopiska fritt svävande alger – växtplankton. Liksom gröna växter på land använder växtplankton solljuset för att producera energi och syre genom fotosyntes. För att algerna ska kunna växa behöver de förutom ljus ett flertal näringsämnen varav de viktigaste är kväve (N) och fSome phytoplankton have the ability to combine phototrophy and heterotrophy within the same individual, which is called mixotrophy. In this thesis, I adress mixotrophy and competitive interactions of mixotrophs and obligate auto- or heterotrophs in relation to the availability of nutrients, light and prey. In addition, I examine the biomass of mixotrophic phytoplankton and their grazing impact on
Samples from several WWTPs in Sweden, operating either with chemical precipitation of phosphorus, biological phosphorus removal or combination of the two, were analysed for separation and dewatering properties. The main parameters of interest were capillary suction time (CST), extracellular polymeric substances (EPS), metal ions concentration, filterability and compressibility of the sludge. Enhan
