Stripping gas is generally used to improve hydrogen yields in fermentations. Since CO2 is relatively easy to separate from hydrogen it could be an interesting stripping gas. However, a higher partial CO2 pressure is accompanied with an increased CO2 uptake in the liquid, where it hydrolyses and induces an increased requirement of NaOH to maintain the pH. This enhances the osmotic pressure in the c
We have previously raised two monoclonal antibodies (7B1, 14F11) recognizing the high-affinity leukotriene B4 receptor, BLT1. They were presently used to determine receptor surface expression in the hematopoietic system. In peripheral blood, BLT1 was primarily recognized in granulocytes, monocytes and, to a lower extent, in certain lymphocytes except the CD4 subpopulation. The expression pattern w
Background: Prevention and treatment of medical issues are the main task of a health service at a youth camp. However, only few reports about organisation and implementation of camp health care are available. This makes it difficult for future camp directors to plan and estimate the health care needed for a certain camp size. We summarize the experience in planning and running health care for the
Objective: To develop evidence-based recommendations for the management of systemic glucocorticoid ( GC) therapy in rheumatic diseases. Methods: The multidisciplinary guideline development group from 11 European countries, Canada and the USA consisted of 15 rheumatologists, 1 internist, 1 rheumatologist-epidemiologist, 1 health professional, 1 patient and 1 research fellow. The Delphi method was u
Fiberoptic bronchoscopy with bronchoalveolar lavage and protected specimen brush technique has become an established method for etiologic diagnosis in severe forms of pulmonary infections during recent years. In this study, including 62 bronchoscopies in 53 patients, a standardized program, covering all important pulmonary pathogens, has been evaluated in a heterogeneous group of patients. Results
The present work aims to study preparation of thin MIP films on a gold-coated QCM resonator in a well-controlled and reproducible manner. A surface-bound photo-radical initiator was used to furnish an imprinting polymerization in a dilute solution of template, functional monomer and crosslinker. Prior to polymerization, the photo-initiator was covalently coupled to a self-assembled monolayer of ca
Operation of a district heating system is accomplished via a sequence of decisions by the operators controlling the system. These decisions are based on expectations of conditions in the system that are not known at decision time. The operators could be helped by a decision support system that computes predictions of future system variables and suggests appropriate control actions given the availa
We have calculated band structures for strained core-shell nanowires involving all combinations of AlN, GaN, and InN, as well as all combinations of AlP, GaP, AlAs, GaAs, InP, InAs, AlSb, GaSb, and InSb, as functions of core and shell radii. This gives 78 combinations, most of which have not been experimentally realized, and provides a quite complete overview of which interesting structures can be
The role of temporal changes and spatial variability in predation risk and prey's means of mitigating such risks is poorly understood in the context of potential threats of global climate change for migratory birds. Yet nest predation, for example, represents a primary source of reproductive mortality in birds. To assess risk birds must spend time prospecting potential breeding sites for cues or s
Most hovering animals, such as insects and hummingbirds, enhance lift by producing leading edge vortices (LEVs) and by using both the downstroke and upstroke for lift production. By contrast, most hovering passerine birds primarily use the downstroke to generate lift. To compensate for the nearly inactive upstroke, weight support during the downstroke needs to be relatively higher in passerines wh
The amount of household refuse has steadily increased in Sweden and this is consistent with the trend in the rest of the European Union. Strategies for household waste reduction includes sorting, recycling, re-use and repair. Two categories of motivational factors determine disposal behaviour, external and internal. The external factors include administrative, economic, information and physical me
This paper describes the participatory process of developing and implementing a prototype model aimed at supporting the Integrated Sustainability Assessment of water resources and policy options at different scales. The model - called the World Cellular Model (WCM) focuses on the representation of agents’ behaviours and their systemic relationships with their environment. This is achieved by exami
Popular Abstract in Swedish Utgångspunkten för denna avhandling har varit att studera användningen av datorer i arbetet utifrån ett mer holistiskt perspektiv än vad som varit brukligt i tidigare traditionell hälsoforskning om datoranvändning, genom att även inkludera arbetsinnehållet som inte utförs med hjälp av datorn. Avhandlingens ansatts skiljer sig således från tidigare traditionell hälsoforsThis thesis aims at investigating computer use at work from a more holistic work content perspective by also studying non-computer work content, in contrast to the previous approach in occupational health research that focused almost solely on computer work content. It was argued here that non-computer work content has also become significant to the overall work situation for computer users. This
At Lund University Faculty of Technology a growing number of teachers develop active student learning methods. These methods can have some advantages in obtaining certain objectives with higher education. To take responsibility for the own learning process and also to learn how to independently handle information and use it in an adequate way are important skills to achieve during an university ed
There are inconsistent and limited data available to assess the relationship between fat intake and risk of epithelial ovarian cancer (EOC). We examined the consumption of total fat, fat sources and fat subtypes in relation to risk of EOC and its major histologic subtypes in the European Prospective Investigation into Cancer and Nutrition which includes incident invasive (n=1095) and borderline (n
Recently, molecular motor gliding assays with actin and myosin from muscle have been realized on semiconductor nanowires coated with Al2O3. This opens for unique nanotechnological applications and novel fundamental studies of actomyosin motor function. Here, we provide a comparison of myosin-driven actin filament motility on Al2O3 to both nitrocellulose and trimethylchlorosilane derivatized surfac
Wetlands can modify and control nutrient fluxes between terrestrial and aquatic ecosystems, yet little is known of their potential as biological buffers and sinks in the biogeochemical silica cycle. We investigated the storage of amorphous silica (ASi) in a central-European riparian wetland. The variation in storage of ASi in the soil of an undisturbed wetland was significantly controlled by two f
Improved understanding of the importance of different surfaces in supporting attached nitrifying and denitrifying bacteria is essential if we are to optimize the N removal capacity of treatment wetlands. The aim of this study was therefore to examine the nitrifying and denitrifying capacity of different surfaces in a constructed treatment wetland and to assess the relative importance of these surf
