A study highlighting several aspects of resonant spectroscopies where fragmentation processes are investigated is described. We focus primarily on understanding the dynamical processes taking place in core-excited states in molecules. An example where fast dissociation and molecular alignment are discussed is given for the ammonia molecule.

Popular Abstract in Swedish Proteiner är helt nödvändiga för alla former av liv på jorden. En typisk cell består till 50-60 % av proteiner, om man bortser från vatten. Det är ett protein, hemoglobin, som transporterar syre från lungorna till kroppens celler och ger blodet dess röda färg. Det är ett protein, alfa- keratin, som bygger upp vårt hår och våra naglar. Det är två proteiner, aktin och myoProtein S is a modular protein and a cofactor in the protein C anticoagulant system. It consists of a Gla-module, a thrombin-sensitive loop, four EGF-modules and a SHBG-like module. Protein S has previously been shown to contain four binding sites with high affinities for Ca²⁺ (K_a>9x10⁵ M^-1 at physiological ionic strength) and at least one of the sites h

The potential and mechanism to reduce acid gases, such as SO2, NOx and HCl by dry Ca-based sorbents have been studied to improve the efficiencies of the process and sorbent utilization. Several natural limestones were tested for SO2 removal. Calcium conversion as high as 45% was achieved within 0.3 s at 1000°C, 1000 ppm SO2 and Ca/S=1. A SO2 removal efficiency of 95% was reached at Ca/S=2. Two m

A comprehensive experimental study of the dynamics and rheology of concentrated aqueous dispersions of polyethylene glycol-grafted colloidal spheres is reported. The study focuses on good solvent conditions, for which excluded-volume interactions dominate. At high concentrations a glass transition is evident from the nondecaying component of the intensity correlation function measured with three-d

Tolerance – respecting those who are different – is arguably of particular importance in an era of globalization, where a potential for economic, social and personal development is increasingly a function of interaction with others different from oneself. We investigate whether globalization induces parents to want to instill tolerance in their children, the main idea being that this would equip t

The Furuta pendulum consists of an arm rotating in the horizontal plane and a pendulum attached to its end. Rotation of the arm is controlled by a DC motor, while the pendulum is moving freely in the plane, orthogonal to the arm. Motivated, in particular, by possible applications for walking/running/balancing robots, we consider the Furuta pendulum as a system for which synchronized periodic motio

In-situ measurements of soot volume fraction in the exhausts of jet engines can be carried out using the laser-induced incandescence (LII) technique in backward configuration, in which the signal is detected in the opposite direction of the laser beam propagation. In order to improve backward LII for quantitative measurements, we have in this work made a detailed experimental and theoretical inves

Mercury (Hg) is regarded as a major environmental concern in many regions, traditionally because of high concentrations in freshwater fish, and now also because of potential toxic effects on soil microflora. The predominant source of Hg in most watersheds is atmospheric deposition, which has increased 2- to >20-fold over the past centuries. A promising approach for supporting current European effo

The photoelectron satellite structure of rubidium and cesium has been investigated following the photoionization of an nd (n= 3,4) inner-shell electron. The intensity ratios of the nd(-1) ms monopole and nd(-1) m'p conjugated satellite lines have been measured at MAX-lab by using high-resolution electron spectroscopy. For rubidium, moreover, the energy dependence of the 3d(j)6s/3d(j)5s and 3d(j)5p

We previously demonstrated that secreted proform(s) of the neutrophil serine protease PR3 (proteinase 3) can down-modulate the fraction of normal human colony-forming unit granulocyte-macrophage (CFU-GM) in S-phase, whereas PR3 extracted from mature neutrophils lacks this ability. The objective of this study was to characterize the structural and functional dissociation between secreted proforms a

Screening for cervical cancer precursors by cytology has been very successful in countries where adequate resources exist to ensure high quality and good coverage of the population at risk. Mortality reductions in excess of 50% have been achieved in many developed countries; however the procedure is generally inefficient and unworkable in many parts of the world where the appropriate infrastructur

The aim is to highlight the influence of patients' gender on Lyme borreliosis and especially erythema migrans (EM), focusing on exposure to tick bites, epidemiology, and the clinical picture. All studies were conducted in the county of Blekinge, located in southeastern Sweden. A prospective study was conducted in 235 individuals (women, n = 110; men, n = 125) engaged in recreational or occupationa

The aim of the present study was to examine autonomic function in response to negatively and positively valenced pictures under different levels of conscious recognition. Heart period variability (HPV) and heart rate (HR) reactivity were studied in 53 males and females who were being shown pictures of angry and happy faces. The pictures, which were backwardly masked, were presented once every 30 s

The main features of the ultraviolet spectrum of acrolein have been studied by a multireference perturbative treatment and by a time dependent density functional approach. The valence and Rydberg transition energies have been calculated and the assignment of the experimental bands has been clarified. The different relaxation trends of the three lowest singlet and triplet excited states have been a

BACKGROUND: Personalized oncology requires molecular analysis of tumor cells. Several studies have demonstrated that cytological material is suitable for DNA analysis, but to the authors' knowledge there are no systematic studies comparing how the yield and quality of extracted DNA is affected by the various techniques used for the preparation of cytological material. METHODS: DNA yield and qualit

The article reports and discusses a long-term qualitative study of forty 8-10 year old students who regularly played a math game during math lessons for 9 weeks. The goal was to explore the relations between (i) some of the pedagogical principles that underlie the game and (ii) the playing practice in terms of what actually takes place when students play the math game during regular math lessons.

Coastal pastures are common agroecosystems adjacent to estuarine areas that can provide valuable habitat for wildlife, particularly for migratory shorebirds. Disentangling the factors that influence coastal pasture use by wintering shorebirds will provide new insights into its role for buffering human disturbances and habitat loss in intertidal areas. We examined whether numbers of two shorebirds

In the production of ethanol from lignocellulosic material, it is necessary to reach a high ethanol concentration after fermentation. Simply increasing the substrate concentration leads to stirring problems and inhibition of the enzymes and yeast in the process. Batch simultaneous saccharification and fermentation (SSF) of steam-pretreated spruce with 13.7% water-insoluble solids (WIS) (25% total
