The gene fusion technique is widely used in protein engineering and in this thesis it constitutes the basis of both the construction of artificial bifunctional enzymes and the display of two novel peptides. Artificial bifunctional enzymes have been used as model systems in the studies of native multifunctional enzymes and proximity effects within these complexes. Two various constructs are descri
A strain of an alkaliphilic bacterium Bacillus halodurans was isolated from a water sample in Lake Shalla, a soda lake in the Ethiopian Rift Valley. From the culture of this isolate, B. halodurans S7, a xylanase which is active in a wide range of pH, with an optimum at about 9-9.5 was purified. When assayed at pH 10, the enzyme was optimally active at 70 ?C. The xylanase was free from any associat
The primary aim of the research project is to analyse the potential for the application of lidar and fluorescence techniques in building investigation, and also to establish a scientific remote-sensing method for surveying and analysing the historical facade that is non-destructive and can be used in-situ. The fluorescence lidar method uses point-monitoring and scanning of areas that can provide m
Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. To study the catalytic oxidation of CO, we have synthesised model CuOx/CeO2 cata
Popular Abstract in Swedish Finkorniga moräner betraktas ofta som problemjordar inom anläggningsbranschen beroende på jordarnas känslighet för förändringar i vatteninnehåll och för deras tjälegenskaper. I dagsläget används endast en begränsad mängd finkorniga moräner i anläggningsbyggande. Huvudmålet med denna avhandling har varit att öka kunskapen om dessa jordars egenskaper och att finna/utvecklFine-grained soils are often regarded as problematic soils in earthworks because of their water- and frost sensitivity. Only limited amounts of fine-grained tills are used as earthwork material today. The main objective of this thesis is to improve the knowledge of how to use and also treat a fine-grained till, so that a greater amount can be utilised as earthwork material. To achieve an increasin
Popular Abstract in English Antonie van Leeuwenhoek is known as the father of microbiology, because he made the first microscopic observation of bacteria in human history, published in 1683. For the naked human eyes, bacterial cells are too small to observe, and the development of microscopy techniques has since then been fundamental for examining bacterial cells. Recent advances in visualizing toCoiled coil proteins emerge as important determinants of bacterial cellular organization. Several such proteins display properties characteristic to metazoan intermediate filament (IF) proteins, and are therefore designated bacterial IF-like proteins. The best studied examples of the latter are crescentin in Caulobacter crescentus that determines the curved cell shape, and FilP (filament forming-p
Expanding hypoxia in the Baltic Sea over the past century has led to the development of anoxic and sulfidic (euxinic) deep basins that are only periodically ventilated by inflows of oxygenated waters from the North Sea. In this study, we investigate the potential consequences of the expanding hypoxia for manganese (Mn) burial in the Baltic Sea using a combination of pore water and sediment analyse
Mobility particle size spectrometers often referred to as DMPS (Differential Mobility Particle Sizers) or SMPS (Scanning Mobility Particle Sizers) have found a wide range of applications in atmospheric aerosol research. However, comparability of measurements conducted world-wide is hampered by lack of generally accepted technical standards and guidelines with respect to the instrumental set-up, me
Objectives The study sought to evaluate the relationship between procedural volume and outcomes with radial and femoral approach. Background RIVAL (RadIal Vs. femorAL) was a randomized trial of radial versus femoral access for coronary angiography/intervention (N = 7,021),which overall did not show a difference in primary outcome of death, myocardial infarction, stroke, or non-coronary artery bypa
Thermal-optical analysis is a conventional method for determining the carbonaceous aerosol fraction and for classifying it into organic carbon, OC, and elemental carbon, EC. Unfortunately, the different thermal evolution protocols in use can result in a wide elemental carbon-to-total carbon variation by up to a factor of five. In Europe, there is currently no standard procedure for determining the
PURPOSE:: To describe a family with an 18-year-old woman with fundus albipunctatus and compound heterozygous mutations in RPE65 whose unaffected parents and 1 female sibling harbored single heterozygous RPE65 mutations. DESIGN:: Observational study. PARTICIPANTS:: Four family members. METHODS:: Clinical examinations included full-field electroretinogram (ffERG) after standard (30-minute) and prolo
Popular Abstract in Swedish Populärvetenskaplig sammanfattning: När udda blir mainstream - om stress och likriktning i växtsamhället I skogen råder stress på många sätt, och precis som i det mänskliga samhället har stressen i växtsamhället ökat under de senaste decennierna. Dessa händelser har heller inte skett oberoende av varandra. Vårt allt snabbare tempo med krav på ökad tillväxt har inte baSoil acidification has become a source of serious concern in many parts of the world. In southern Sweden, the deposition of acidifying substances, such as nitrogen and sulphur compounds, has decreased the mean pH of forest soils by almost one unit since the 1950s. Apart from H+ ions themselves being harmful to plant roots, the potential toxicity of aluminium (Al) is increased when pH drops below 5
The interactions between uncharged polymers, e.g. ethyl(hydroxylethyl)cellulose (EHEC) and some model polymers, and ionic surfactants in aqueous solution has been studied by using isothermal titration and differential scanning calorimetry. We found that titration calorimetry could give quite detailed information about polymer - surfactant interactions. Values for the critical aggregation concentra
Popular Abstract in Swedish Ett beta-fosfoglukomutas i kolhydrat-metabolismen hos Lactococcus lactisPhosphoglucomutase (PGM) catalyzes the reversible conversion of glucose 1-phosphate to glucose 6-phosphate. Two distinct forms of PGM have been purifed and charactierized in Lactococcus lactis growing on maltose: one specific for the alpha-isomer, and the other specific for the beta-isomer of glucose 1-phosphate. Beta-PGM was purified and polyclonal antisera to the enzyme were generated. Beta-PGM
General obesity, as reflected by BMI, is an established risk factor for esophageal adenocarcinoma (EAC), a suspected risk factor for gastric cardia adenocarcinoma (GCC) and appears unrelated to gastric non-cardia adenocarcinoma (GNCC). How abdominal obesity, as commonly measured by waist circumference (WC), relates to these cancers remains largely unexplored. Using measured anthropometric data fro
Traumatic brain injury (TBI) is one of the leading causes of death in children worldwide. Emerging evidence suggests that alterations in mitochondrial function are critical components of secondary injury cascade initiated by TBI that propogates neurodegeneration and limits neuroregeneration. Unfortunately, there is very little known about the cerebral mitochondrial bioenergetic response from the i
Precise geochronology, combined with paleomagnetism on mafic intrusions, provides first-order information for paleoreconstruction of crustal blocks, revealing the history of supercontinental formation and break-up. These techniques are used here to further constrain the apparent polar wander path of the Kaapvaal Craton across the Neoarchean-Paleoproterozoic boundary. U-Pb baddeleyite ages of 2441
