The on-line computational demands of model predictive control (MPC) often prevents its application to processes where fast sampling is necessary. This report presents a strategy for reducing the computational delay resulting from the on-line optimization inherent in many MPC formulations. Recent results have shown that feasibility, rather than optimality, is a prerequisite for stabilizing MPC algo
Detergent/polymer aqueous two-phase systems are studied as a fast, mild and efficient general separation method for isolation of labile integral membrane proteins. Mechanisms for phase behaviour and protein partitioning of both membrane-bound and hydrophilic proteins have been examined in a large number of detergent/polymer aqueous two-phase systems. Non-ionic detergents such as the Triton series
A diagnosis-antibiotic prescribing study was performed in 5 counties in Sweden during 1week in November in the y 2000 and 2002, respectively. As part of the study, the characteristics and clinical management of patients who received diagnoses of urinary tract infections (UTIs) ( n = 1564) in primary care, were analysed. 85% of the visits were by women, and 74% of all consultations were diagnosed a
During the course of development the motor repertoire of animals and humans alike go through dramatic changes. New motor patterns arise; movements become coordinated, improve in precision and are at the same time continuously calibrated to the changing body dimensions. The cerebellum is critical for movement coordination and adaptation in adults. Also, interfering with cerebellar development durin
Trees are present in the everyday life of most people, as eye-catchers, meeting points, obstacles, etc. Memories of people, events, and actions are also often connected to specific trees. But the same tree may acquire a range of different meanings, depending on personal experience. Adopting an analytical cultural perspective, "Thinking Trees: An Ethnological Study of Narratives About the Meaning o
The rehabilitation and release of injured or ill raptors and owls is widespread. The overall aim of this intervention is the successful reintroduction of the bird into the wild population. Though many injuries are treatable, it is thought that vision-impaired birds have no change of survival and their release is refused. Here we report a case study and give a description of the rehabilitation and

The efficacy of a short (Group I) and a prolonged (Group II) course with ciprofloxacin was assessed in patients undergoing transurethral prostatic resection and compared with that of controls without antibiotic (Group III). Both regimens significantly reduced the frequency of post-operative bacteriuria (p less than 0.01) and of severe infectious complications (p = 0.004) compared to the controls.
Popular Abstract in Swedish Denna avhandling utgör den första delen i en planerad serie på tre rapporter med utgångspunkt i data insamlade läsåret 1993/94 i årskurs 9 vid en grundskola, där det lokala skolprojektet Tonåringens livssituation och livstolkning genomförts i ämnet religionskunskap. Det övergripande syftet med studien är att undersöka vilka centrala livsvärden eleverna ger uttryck för iThis dissertation makes up the first report based on data collected during the project "Teenagers: aspects of their life style and attitudes" (Tonåringens livssituation och livstolkning) in the subject Religious Studies taken by pupils attending Year 9 during the 1993/94 school year. The general aim of the study is to discover the central values of life which pupils hold, as expressed in an essay
Interactions between patients and physiotherapists have been studied by various researchers. Some results indicate that physiotherapists have an awareness of underlying emotions, but often respond only on an intellectual level. It seems that verbally expressed emotions may be important for interaction between physiotherapists and patients during treatment. Aim The aim of this study was to investi
Human bone-marrow-derived mesenchymal stem cells (MSC) are responsible the remodeling of human tissue. However, damaged aortic valves are lack the ability to regenerate which is an active cell-mediated process. Diseased aortic valve remodeling has similarities even to bone formation. In this study, the prerequisites for cultured MSCs to undergo osteoblastic differentiation on aortic valves were ex
A method is presented for identification of positional isomers of dichlorinated fatty acids, based on derivatization to picolinyl esters prior to gas chromatographic/mass spectrometric analysis in the electron ionization mode. The mass spectra of the picolinyl esters showed structure-specific fragmentation patterns. By using the picolinyl ester, 5,6-dichlorotetradecanoic acid was identified as a m
Background and Purpose-It is disputed whether there are sex differences in management and outcome after stroke; early studies have shown inconsistent results. The objective of this study was to verify and explain differences between men and women in management and outcome after stroke in a national perspective. Methods-In 2001, 20 761 stroke patients were registered in Riks-Stroke, the national qu
