Biocatalysis in organic media offers very attractive methods to prepare fine chemicals. The biocatalyst performance regarding activity, stability and enantioselectivity will determine the viability of the bio-process. Therefore, the understanding and optimization of the parameters influencing enzyme performance in organic solvents are extremely important. In this thesis, reactions catalysed by hyd
The purpose of the Gramte program is to meet the needs of university students who feel that they are not mastering the grammatical terminology needed for studying linguistics or foreign languages. In all learning contexts it is important to have the adequate background knowledge. This is even more crucial when it concerns the basic concepts and terminology which will be used by the teachers during
A series of spinel type Fe-V-O phases were prepared with V/Fe atomic ratios ranging from 0 to 1 and were used for methanol oxidation to formaldehyde. X-ray powder diffraction shows that the basic spinel-type structure is retained after use of the samples in methanol oxidation. Compared with the freshly prepared samples, in and ex situ analyses of the samples with XANES show that both V and Fe are
Popular Abstract in Swedish Bakgrund: Signalsystem Alla flercelliga organismer är beroende av informationsöverföring mellan celler. Det behövs signaler från andra celler för att reglera tillväxt, ämnesomsättning m. fl. funktioner i olika vävnader. Oftast överförs signalerna via kemiska ämnen som antingen verkar i hela kroppen (hormoner) eller lokalt. När dessa ämnen når målcellen, binds de till eThe cyclic nucleotide signalling systems are important in vascular smooth muscle and in the immune system, and are of interest from a pharmacological point of view. Drugs which interfere with the cyclic nucleotide levels have profound effects on heart, blood vessels and airways and have actual or potential use in several important diseases, such as heart failure, hypertension, arteriosclerosis, as
Four years have passed since January 1996 when retail competition was introduced in the Swedish electricity market. These years have been characterized by a rapid restructuring of the electricity supply industry through mergers and acquisitions, lower electricity prices, and a search for new marketing strategies in the competitive market. General trends and the results of two market surveys, under
In this study we compare two types of Large Eddy Simulation (LES) turbulent combustion models with experimental data for a low swirl stabilized turbulent lean premixed flame. Such flames are a great challenge to numerical simulations since they are unsteady and sensitive to boundary conditions, and details of the experimental set-up. The two classes of LES turbulent combustion models considered ar
Abstract in UndeterminedPurposeThe purpose of this article is to explore and classify themes and challenges in making urban freight distribution sustainable.Design/methodology/approachThe study has a cross sectional design which started by a narrative literature review and analysis of a sample of related literature (like peer-reviewed articles and EU (European Union) documents). It ended with comp
The Baltic Sea Region is rapidly becoming one of the world’s more competitive regions. The region is capitalising on its strengths and making the most of its diversity to stimulate innovation, build a strong pool of skilled labour and foster entrepreneurship. A deep spirit of co-operation and integration has led the Baltic Sea countries to set up ambitious governance frameworks to pursue economic
Backgrounds. A focus on psychiatric rehabilitation in order to support recovery among persons with severe mental illness (SMI) has been given great attention in research and mental health policy, but less impact on clinical practice. Despite the potential impact of psychiatric rehabilitation on health and wellbeing, there is a lack of research regarding the model called the Psychiatric Rehabilitat
In this study a column leaching method for investigation of hydrophobic organic contaminants (HOCs) leaching from soil was developed. The method set-up is based on a recycled flow of sterile water through a soil column with a sedimentation chamber mounted on top of the column, in connection with on-line filtration. The combination of a sedimentation chamber and an on-line filtration enables the me
The distribution of polarization in the overcast sky has been practically unknown. Earlier the polarization of light from heavily overcast skies (when the Sun's disc was invisible) has been measured only sporadically in some celestial points by point-source polarimetry. What kind of patterns of the degree p and angle a of linear polarization of light could develop after transmission through a thic
Popular Abstract in Swedish Denna avhandling handlar om hur personer, som insjuknat i stroke, beskriver sina upplevelser och erfarenheter av att leva med stroke och hur de lär sig hantera sin livssituation. Kunskaper om läroprocesser i en livsomställning, som insjuknande i stroke innebär, är betydelsefulla för att kunna förstå, möta och stödja människor i sådana situationer. Under de senaste årtioThis thesis concerns how people with stroke describe their experiences of life with stroke and how they learn to live with stroke. In the western world the interest for research in lived experiences has increased. This might be due to the higher rate of people with illness and lifelong diseases. The aim of the study is to analyze stories from persons with stroke of their lived experiences of life
The use of bio-fuels is becoming more important because of the environmental benefits associated with these fuels. Deactivation of SCR catalysts applied in bio-fuel plants is a major problem due to the high potassium content of bio-fuels and therefore, great potential lies in finding regeneration processes that can be used commercially. Exposing the catalyst surface to sulphate groups generated by
Background & Aims: In the stomach, Helicobacter pylori is found both in the mucus layer and adhering to the gastric epithelium. The aim of this study is to characterize the binding of H. pylori to human gastric mucins. Methods:H. pylori strains that bind the Lewisb (Leb) structure (via the BabA adhesin) and/or sialylated structures, along with isogenic adhesion deletion mutants, were used to i
The management of construction tolerances is a necessary and routine part of the construction activity and is normally brought to our attention only when failures are reported. In a study of tolerance management, the authors found widespread evidence of the same failures and the reasons for them. There seems to be no shortage of experience of the effects of failures in tolerances or of knowledge a
The innate immune system is the first line of defense against invading microbes. Its specificity relies a great deal on host pattern recognition molecules that sense pathogen-associated molecular patterns of the invading pathogen. However, full protection is not always guaranteed, and some early defense mechanisms involved in bacterial killing, such as the complement system, can also exert cytolyt
With its unprecedented light-collecting area for night-sky observations, the Cherenkov Telescope Array (CTA) holds great potential for also optical stellar astronomy, in particular as a multi-element intensity interferometer for realizing imaging with sub-milliarcsecond angular resolution. Such an order-of-magnitude increase of the spatial resolution achieved in optical astronomy will reveal the s
Abstract Objective. To study the associations between active choice of primary care provider and healthcare utilization, multimorbidity, age, and sex, comparing data from primary care and all healthcare in a Swedish population. Design. Descriptive cross-sectional study using descriptive analyses including t-test, correlations, and logistic regression modelling in four separate models. Setting and
BACKGROUND: There is a lack of information on positive work factors among health care workers. OBJECTIVE: To explore salutogenic work-related factors among primary health care employees. METHOD: Questionnaire to all employees (n = 599) from different professions in public and private primary health care centers in one health care district in Sweden. The questionnaire, which had a salutogenic persp
