The adsorption from a mixture of SDS and β-Lactoglobulin, 1:5 (), onto a methylated silica surface was studied in situ by ellipsometry. The amounts adsorbed from different concentrations of the mixture, at pH 7, were compared with those adsorbed from the corresponding pure SDS and β-lactoglobulin solutions. At high concentrations of the mixture, where the CMC of SDS is approached or exceeded, the The adsorption from a mixture of SDS and β-Lactoglobulin, 1:5 (), onto a methylated silica surface was studied in situ by ellipsometry.

Pesticides represent one of the greatest threats to bees and other beneficial insects in agricultural landscapes. Potential exposure is generated through compound- and crop-specific patterns of pesticide use over space and time and unique degradation behavior among compounds. Realized exposure develops through bees foraging from their nests across the spatiotemporal mosaic of floral resources and

Background: Concern has been raised regarding the mounting collective radiation doses from computed tomography (CT), increasing the risk of radiation-induced cancers in exposed populations. Purpose: To compare radiation dose and image quality in a chest phantom and in patients for the diagnosis of pulmonary embolism (PE) at 100 and 120 peak kilovoltage (kVp) using 16-multichannel detector computed

Background: Myeloid cells have been associated with physiological and pathological angiogenesis, but their exact functions in these processes remain poorly defined. Monocyte-derived tissue macrophages of the CNS, or microglial cells, invade the mammalian retina before it becomes vascularized. Recent studies correlate the presence of microglia in the developing CNS with vascular network formation,

In the present thesis molecular genetic methods were used to address different biological and clinical aspects of Philadelphia (Ph) chromosome-positive leukemias and the BCR and ABL genes. In the first study, children with Ph-positive chronic myeloid leukemia (CML) were found to have essentially the same breakpoint locations in BCR as adults, a pattern which differs from the one seen in Ph-positiv

Popular Abstract in English Figure 1: Electron microscopy image of mesoporous material seen from above. The left image shows a possible shape of a silica particle (scale bar: 1 μm). The right image shows the mesopores in the particle (grey color) with the silicon dioxide walls (black color) (scale bar: 150 nm). Poly(N-isopropylacrylamide) (PNIPAAM) is a polymer that can provide the active part forMesoporous silica materials, such as SBA-15, have potential as biocompatible carriers for pharmaceutical applications as well as mini-reactors in e.g. catalysis. This potential arises from their well-defined porous structure on the nanometre scale accompanied by a high internal surface area (800 - 1000 m2/g). This work addresses the following issues. i) Surface grafted PNIPAAM was found to be loca

Popular Abstract in Swedish Denna avhandling handlar om hur företag visar, och kan visa, miljöhänsyn vid upphandling av godstransporttjänster. Transporter är en starkt bidragande, och växande, faktor till många miljöproblem såsom den förstärkta växthuseffekten och hälsofarliga partiklar i luften. Behovet av transporter ökar ständigt till följd av exempelvis lokalisering av produktion till låglöneThe logistical activity of transport is one of the largest contributors to several environmental problems. One efficient and effective way to decrease the environmental impact from transports is to implement changes in the logistically related strategies and activities applied, such as the selection of transport suppliers. Consideration of the environmental aspect when purchasing transport servic

Background: The clinical benefit of combining long-acting beta(2)-agonists with inhaled corticosteroids rather than doubling the dose of corticosteroid has been well-documented. However, there are concerns that this might result in a masking of underlying airway inflammation. Objective: The aim of this study was to test the hypothesis that the addition of the long-acting beta(2)-agonist salmeterol

We compared the Q10 relationship for root-derived respiration (including respiration due to the root, external mycorrhizal mycelium and rhizosphere microorganisms) with that of mainly external ectomycorrhizal mycelium and that of bulk soil microorganisms without any roots present. This was studied in a microcosm consisting of an ectomycorrhizal Pinus muricata seedling growing in a sandy soil, and

We have used DNA microarrays to survey rates of mRNA decay on a genomic scale in early stationary-phase cultures of Bacillus subtilis. The decay rates for mRNAs corresponding to about 1500 genes could be estimated. About 80% of these mRNAs had a half-life of less than 7 min. More than 30 mRNAs, including both mono- and polycistronic transcripts, were found to be extremely stable, i.e. to have a ha

The global governance of AIDS is dependent for its success on the concerted efforts of actors from both local and global levels, thus challenging the current international organization based on state sovereignty. The study seeks to understand the processes behind the creation of partnerships among the many different nongovernmental organizations (NGOs) active in AIDS politics and the intergovernme

The possible teratogenic effect of erythromycin therapy, noted previously, was studied. Women who had taken erythromycin or penicillin V in early pregnancy and their infants were studied, using the Swedish Medical Birth Register where information on drug use during pregnancy was recorded based on interviews in early pregnancy. The risk for any congenital malformation after erythromycin therapy (bu

This doctoral dissertation concerns two-dimensional frequency estimation for modal analysis of single-input multiple-output impact responses from circularly cylindrical objects. The application is within detection of internal defects in trunks of spruce. The material consists of impact responses from 94 trees, with 66 sound and 28 in various stages of decay. Paper I proposes that modal analysis o

Popular Abstract in Swedish Utgångspunkten i den här avhandlingen är det faktum att många av Sveriges kommuner har problem med minskande invånarantal och en skev befolkningsstruktur. Den här typen av utvecklingsmönster medför ofta svårigheter för en kommun att attrahera människor att flytta till kommunen, och att upprätthålla en tillfredsställande kommunal service. I sin förlängning kan detta få nMany of Sweden’s municipal districts show a population decline as well as an uneven population distribution. This pattern is neither desirable nor socially sustainable. Sustainable development is a well-known term often discussed from an ecological perspective. At the same time it is established that social and ecological sustainability are closely linked in several ways. In this dissertation soci

The addition of crop residues is a common farming practice to increase the organic carbon content of agricultural soils with particular importance in organically managed crops. Residues can be added either from the crop plant itself or from other plants and the type of litter may differentially affect decomposer populations. Effects of litter addition may cascade up to affect generalist predators

Background: Scientific reviewing is a voluntary process to determine if a manuscript deserves publication. REVIEW means: Responsibly Evaluate, Verify and Improve the manuscript, Educate the authors and editors, and Weigh your expert opinion against the submitted work. Provide your review in a respectful, unbiased and timely manner. Review Methods: Make sure editors know about your willingness to r

In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. Multiservice broadband networking generally refers to the ability to handle widely disparate traffic streams s

With the global population projected to reach eight billion by 2022, the world faces significant challenges associated with rapid urbanization. The migration of individuals from rural to urban areas in search of improved opportunities exacerbates the strain on resources, posing obstacles such as housing shortages, infrastructure demands, and food scarcity in growing cities. This thesis aims to add

This study comprehensively evaluated the global warming potential of an office building in a newly built Scandinavian neighbourhood seeking to reach sustainability. The primary objective of the research was to support the city authorities of Helsingborg by providing valuable insights into actual carbon emissions at the building level and proposing measures to minimize these emissions to achieve cl
