Excitation and emission polarization dependence of fluorescence intensity of single LH2 complexes from Rhodopseudomonas acidophila 10050 and Rhodobacter sphaeroides is reported. The results are presented as two-dimensional polarization plots and interpreted in terms of tilted light harvesting complexes indicating that sample preparation leads to partially oriented LH2 cylinders. An alternative exp
Spelifiering inom utbildning är ett väldigt aktuellt ämne idag och det pågår mycket forskning och många projekt för att undersöka hur spel främjar lärande.
The pedestrian safety problem is huge in all developing countries. The main aims of the project are therefore: 1/To understand pedestrian safety problem in a developing country, 2/To identify feasible traffic calming measures. International experiences were complemented by field studies at seven sites in the city of Jaipur. A wide range of field studies were made, out of which traffic conflict stu
In this review, starch behavior is described from molecules in solution to the use of starch in products. The determination of molecular characteristics with asymmetrical flow field-flow fractionation is described, and the behavior of starch in binary solutions is discussed. The organization of starch in granules and the changes in organization during gelatinization and retrogradation are then des
The atomic structure and spectra of ten tungsten ions have been calculated using the Flexible Atomic Code. The calculations yield energy levels, radiative lifetimes, spectral line positions, transition probability rates, and oscillator strengths for the tungsten ions isoelectronic to germanium, W42+, through vanadium, W51+. Collisional-radiative models for high-temperature, low-density plasmas hav

Popular Abstract in Swedish Lymfom är en grupp tumörsjukdomar som uppkommer från de vita blodkropparna i vårt immunförsvar. Diffust storcelligt B-cellslymfom (DLBCL) är en av de mest aggressiva varianterna av lymfom och uppkommer från den typen av vita blodkroppar som kallas B-celler. Varje år drabbas ca 500 personer i Sverige av DLBCL. Typiska symtom är hastigt tillväxande lymfkörtlar samt viktneDiffuse large B-cell lymphoma (DLBCL) is an aggressive and heterogeneous disease. Identification of prognostic and predictive markers is important to design individualised and effective treatment strategies. This thesis describes different approaches to search for molecular prognostic markers and an attempt to overcome chemotherapy resistance in DLBCL. In the first study it was investigated whet
Expression of fibroblast growth factor-8 (FGF-8) is increased in a large number of breast cancers. In in vitro and in vivo breast cancer models FGF-8 promotes growth, invasion and angiogenesis. In the present work we have studied the mechanisms by which FGF-8b and its receptors (FGFR1-3) promote breast cancer cell growth using S115 murine and human MCF-7 breast cancer cell lines in in vitro and i
The growing complexity of industrial robot work-cells calls for the use of advanced orchestration techniques to promote flexibility and reusability. This paper presents a solution based on service-oriented platforms that endorses the separation of concerns, coordination and execution. The execution is kept inside each individual device and their functionality is exposed via automatic generation of
Background: Principles of brain plasticity is used in the treatment of patients with functional limitations to improve sensorimotor function. Training is included in the treatment of knee injury to improve both patient-reported function and sensorimotor function. However, impairment in sensorimotor function often persists despite training. Therefore, it was suggested that training programs need to
Background: Published associations between dietary carotenoids and vitamin C and bladder cancer risk are inconsistent. Biomarkers may provide more accurate measures of nutrient status. Objective: We investigated the association between plasma carotenoids and vitamin C and risk of urothelial cell carcinoma (UCC) in a case-control study nested within the European Prospective Investigation into Cance
Viruses can be described as biological objects composed mainly of two parts: a stiff protein shell called a capsid, and a core inside the capsid containing the nucleic acid and liquid. In many double-stranded DNA bacterial viruses (aka phage), the volume ratio between the liquid and the encapsidated DNA is approximately 1:1. Due to the dominant DNA hydration force, water strongly mediates the inte
Anthropogenic acidification has reduced soil pH and released potentially toxic aluminium (Al) ions in many regions. This investigation examines whether increased acidity has caused genetic adaptation to acidic conditions within the grass species Elymus caninus, Poa nemoralis, Deschampsia cespitosa and D. flexuosa. We sampled tussocks (genets) of each species in two regions of southern Sweden, diff
This paper is based on a new procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints. The new procedure is motivated by the challenges of output feedback control design for the 3-state Moore-Greitzer compressor model. First, we use conditions for stability of a transformed system and the associated matching conditions to find the data of the st
In autobiographical writing, the mirror is not only a privileged metaphor for the genre as a whole; it also functions as a primary administrator of boundaries, demarcating the space of the self from the foreign, the chaotic, the unknown. The mirror metaphor is not a gender neutral one: in Western elite culture the mirror has served to reinforce the patriarchal dichotomy between man/mind and woman/
Background: Previous research has focused exclusively on weight loss or weight maintenance following weight loss, i.e. secondary weight maintenance (SWM). The long-term results of SWM have been modest, suggesting that preventing initial weight gain among normal weight or overweight individuals, i.e. primary weight maintenance (PWM), may be more successful. The aim of this study was to compare the
