As the need to limit the effect of climate change gets stronger, the transition to sustainable energy solutions becomes very important. Solar thermal energy and green hydrogen production represent two quite promising sustainable fields towards decarbonizing industrial processes and energy sectors. This thesis presents an extensive simulation and performance analysis of a solar thermal energy syste
Flow-ELISA measurements of the monoclonal antibody concentration in cultivation broth containing murine hybriboma cells were carried out using a small expanded-bed column (0.5×2.5 cm) charged with protein A. A new specialised pellicular agarose/stainless steel matrix designed for high flow rates with fast mass transport properties was used. Special care was taken to get an efficient flow distr
The electrochemically coated conducting paper based point-of-care diagnostics using amperometric sensing principles for troponin detection has been demonstrated in the present report. The cost-effective and stable conducting polymer coating was achieved on papers using screen printing followed by electrochemical deposition techniques for the first time. The cyclic voltammetric analysis has reveale
Fast and accurate collision detection between geometric bodies is essential in application areas like virtual reality, animation, simulation, games and robotics. In this work, we address the collision detection problem in applications where deformable bodies are used, which change their overall shape every time step of the simulation. We propose and evaluate suitable bounding volume trees for defo
An environmentally benign and volume efficient process for enzymatic production of alkanolamides is described. Immobilized Candida antarctica lipase B, Novozym (R) 435, was used to catalyze the condensation of lauric acid with monothanolamine. The raction temperature of 90 degrees C was required to keep the reactants in a liquid state. Atepwise addition of the amine minimized problems caused by th
Background: A European concerted action (the EuroNatal study) investigated differences in perinatal mortality between countries of Europe. This report describes the methods used in the EuroNatal international audit and discusses the validity of the results. Methods: Perinatal deaths between 1993 and 1998 in regions of ten European countries were identified. The categories of death chosen for the s
Background: Image-guided radiotherapy (IGRT) facilitates the delivery of a very precise radiation dose. In this study we compare the toxicity and biochemical progression-free survival between patients treated with daily image-guided intensity-modulated radiotherapy (IG-IMRT) and 3D conformal radiotherapy (3DCRT) without daily image guidance for high risk prostate cancer (PCa).Methods: A total of 5
Background/Aims Self-rated health before, during and after pregnancy is important for women s quality of life and promotes bonding between mother and child. However, diverse aspects of care models influence women s experiences during pregnancy. This study aimed to investigate low?risk women s self-rated health during the perinatal period in relation to different models of care in Sweden. Methods A
PURPOSE: To investigate the role of pelvic floor devices (e.g., biofeedback, electrical stimulation, magnetic stimulation, or their combination) as adjunctive treatments in pelvic floor muscle training (PFMT) in stress urinary incontinence (SUI) after radical prostatectomy.MATERIALS AND METHODS: A systematic review with meta-analysis. We searched for randomised controlled trials (RCTs) and prospec
Force feedback (FF) is a technology which is very interesting in the context of human machine interfaces. This as it is usable as a haptic interface, which makes it possible to model and simulate objects and textures. One problem with haptic FF devices today is that most of them are of professional or research standard, which makes them expensive. The technology of FF have also been introduced in
I have briefly outlined different levels of scale in the discussion of centre–periphery, from a local to a more global perspective. I have tried to show that the concepts of centre and periphery cannot be applied without qualification. Different realities are concealed behind them. The common factor is nevertheless that they signal some kind of contacts, in the form of giving and taking, of power,
New Phytologist (2010) Summary *Obligate mutualisms involving actively pollinating seed predators are among the most remarkable insect-plant relationships known, yet almost nothing is known about the chemistry of pollinator attraction in these systems. The extreme species specificity observed in these mutualisms may be maintained by specific chemical compounds through 'private channels'. Here, we
1. The topographical organization of mossy fibre input to the forelimb area of the paravermal C3 zone in cerebellar lobules IV and V was investigated in barbiturate-anaesthetized cats and compared with the previously described microzonal organization of climbing fibre input to the same part of the cortex. Recordings were made in the Purkinje cell and granule cell layers from single climbing fibre
The enzymatic hydrolysis process can be used to produce bioethanol from softwood, which are the dominating raw material in the Northern hemisphere. This thesis deals with the development of the process focusing on the pretreatment and the enzymatic hydrolysis stages. The influence of pretreatment conditions on sugar yield, and the effect of inhibitors on the ethanol yield, were investigated for s
Evaluation of various methods in clinical practice is often based on interpretations by two or more observers. Such data need to be analysed with correct statistics, or the results and conclusions may be misleading. In this study, the use of measures of agreement for ordinal data in five international nursing journals is reviewed and various methods for measuring agreement are presented and discus
