Infrastructures, lock-in, and sustainable urban development: the case of waste incineration in the Goteborg Metropolitan Area
This article explains how infrastructures with a sustainability record may evolve over time into a lock-in that slows the emergence of more sustainable urban infrastructures. A study of waste incineration in the Goteborg Metropolitan Area, Sweden, serves as an illustrative case. Taking leads from Unruh (2000, 2002), four rationales of lock-in are identified in the case: institutional, technical, c
Investigation and compensation of the nonlinear response in photomultiplier tubes for quantitative single-shot measurements.
A concept for time-sensitive optical detectors is described that shows how to confirm whether the detection device is operating in the linear response regime. By evaluating the recorded time decay of a thermographic phosphor, even weak saturation effects far from obvious situations can be identified and further related to either optical or electrical saturation. The concept has been validated by r
C-Kit as an Oncogenic Tyrosine Kinase - Regulation and Dysregulation of Signaling Pathways
It is well known that increased growth and survival of cancer cells often is a result of dysregulated kinase activity and aberrant kinase signaling. The receptor tyrosine kinase c-Kit and its ligand SCF are contributors to this phenomenon in a variety of human cancers, for example hematological malignancies, germ cell tumors and gastrointestinal stromal tumors. In this thesis I have investigated
Clinical prediction of 5-year survival in systemic sclerosis: validation of a simple prognostic model in EUSTAR centres
Objective Systemic sclerosis (SSc) is associated with a significant reduction in life expectancy. A simple prognostic model to predict 5-year survival in SSc was developed in 1999 in 280 patients, but it has not been validated in other patients. The predictions of a prognostic model are usually less accurate in other patients, especially from other centres or countries. A study was undertaken to v
Change in surface properties of Microthrix parvicella upon addition of polyaluminium chloride as characterized by atomic force microscopy.
The filamentous bacterium Microthrix parvicella causes severe separation and foaming problems at wastewater treatment plants (WWTPs). An effective control of the bacterium in activated sludge WWTPs can be accomplished by dosage with polyaluminium chloride (PAX-14). The purpose of this study was to investigate whether addition of PAX-14 affects surface properties such as the hydrophobicity of the b
Deregulation of protein phosphatase expression in acute myeloid leukemia
Acute myeloid leukemia (AML) is a highly malignant disease of myeloid cell line. AML is the most frequent adult leukemia with inadequate treatment possibility. The protein phosphatases are critical regulators of cell signaling, and deregulation of protein phosphatases always contribute to cell transformation. Although many studies established a relationship between protein phosphatases and leukemi
Dietary fat and breast cancer risk in the European Prospective Investigation into Cancer and Nutrition
Background: Epidemiologic studies have produced conflicting results with respect to an association of dietary fat with breast cancer. Objective: We aimed to investigate the association between fat consumption and breast cancer. Design: We prospectively investigated fat consumption in a large (n = 319 826), geographically and culturally heterogeneous cohort of European women enrolled in the Europea
Measurement of the W -> tau nu(tau) cross section in pp collisions at root s=7 TeV with the ATLAS experiment ATLAS Collaboration
The cross section for the production of W bosons with subsequent decay W -> tau nu(tau) is measured with the ATLAS detector at the LHC. The analysis is based on a data sample that was recorded in 2010 at a proton-proton center-of-mass energy of root s = 7 TeV and corresponds to an integrated luminosity of 34 pb(-1). The cross section is measured in a region of high detector acceptance and then ext

delta-Aminolevulinic acid dehydratase genotype predicts toxic effects of lead on workers' peripheral nervous system
There is a wide variation in sensitivity to lead (Pb) exposure, which may be due to genetic susceptibility towards Pb. We investigated whether a polymorphism (rs1800435) in the delta-aminolevulinic acid dehydratase (ALAD) gene affected the toxicokinetics and toxicodynamics of Pb. Among 461 Chinese Pb-exposed storage battery and 175 unexposed workers, allele frequencies for the ALAD1 and ALAD2 alle

Utilization of medical healthcare among older people In relation to long-term municipal care
The overall aim of this thesis was to investigate utilization of medical healthcare, i.e. hospital care and outpatient care, over a period of 1 to 5 years among people aged 65 years or older. The aim was further to investigate medical healthcare utilization in relation to the predisposal factors age and sex; the enabling factors functional ability, cognitive ability, informal care, municipal long-
PROJEKT HÖGPRESTERANDE BETONG 1991-1997 : Lista över rapporter publicerade vid avd Byggnadsmaterial, LTH
Ett nationellt svenskt forskningsprogram HÖGPRESTERANDE BETONG finansierat av de statliga organisationerna NUTEK och BFR och ett antal företag i byggbranschen genomfördes under åren 1991‐1997. I programmet deltog forskare från de fyra tekniska högskolorna CTH, KTH, LuTH (nuvarande LTU) och LTH. Dessutom deltog forskare från Cement och Betongforskningsinstitutet, CBI, samt forskare från olika finanA national Swedish research program HIGH PERFORMANCE CONCRETE was sponsored by the governmental organizations NUTEK and BFR and by a number of private companies within the building sector. The program was performed during the years 1991‐1997. Researchers from four Swedish technical institutes, from the Swedish Cement and Concrete Research Institute and from private companies took part in the progr
Characterisation of a transcriptome to find sequence differences between two differentially migrating subspecies of the willow warbler Phylloscopus trochilus
Background: Animal migration requires adaptations in morphological, physiological and behavioural traits. Several of these traits have been shown to possess a strong heritable component in birds, but little is known about their genetic architecture. Here we used 454 sequencing of brain-derived transcriptomes from two differentially migrating subspecies of the willow warbler Phylloscopus trochilus
Tautomerism in cytosine and uracil: an experimental and theoretical core level spectroscopic study
The O, N, and C 1s core level photoemission spectra of the nucleobases cytosine and uracil have been measured in the vapor phase, and the results have been interpreted via theoretical calculations. Our calculations accurately predict the relative binding energies of the core level features observed in the experimental photoemission results and provide a full assignment. In agreement with previous
The relationship between the key elements of Donabedian's conceptual model within the field of assistive technology.
Previous research has suggested that there is a relationship between the three key components of Donabedian's conceptual model for quality assessments: structure of care, process, and outcome of care. That is, structure predicted both process and outcome of care, and better processes predict better functional outcomes and user satisfaction. The results in this study involving samples of Danish and
Size evolution of electronic properties in free antimony nanoclusters
The evolution of electronic properties in free antimony (Sb) nanoclusters as a function of the cluster size has been studied experimentally using synchrotron radiation. Antimony 4d core-level and valence-band regions have been probed, and the 4d binding energies and valence ionization potentials of clusters of various mean sizes have been determined. The binding-energy shifts with respect to polyc
