The process of charm quark fragmentation is studied using D (* +/-) meson production in deep-inelastic scattering as measured by the H1 detector at HERA. The parameters of fragmentation functions are extracted for QCD models based on leading order matrix elements and DGLAP or CCFM evolution of partons together with string fragmentation and particle decays. Additionally, they are determined for a n
Cancer is a disease characterized by deregulation of cellular functions. The means by which these changes occur may differ among cancer types. However, common to all cancers are that they have changed the genetic programs that determine their characteristics. Genetic programs are mainly regulated by the action of transcription factors. Changes in transcription factor activity and modification of p
Background: Asthma is often poorly controlled and guidelines are often inadequately followed in medical practice. In particular, the prescription of non-asthma-specific drugs can affect the quality of care. The goal of this study was to measure the frequency of the prescription of antibiotics and anxiolytics/hypnotics to asthmatic patients and to look for associations between sex or age and the pr
A vibronic exciton model is applied to explain the long-lived oscillatory features in the two-dimensional (2D) electronic spectra of the Fenna-Matthews-Olson (FMO) complex. Using experimentally determined parameters and uncorrelated site energy fluctuations, the model predicts oscillations with dephasing times of 1.3 ps at 77 K, which is in a good agreement with the experimental results. These lon
Background: Epidemiological studies have shown considerable heritability of blood pressure, thus suggesting a role for genetic factors. Previous studies have shown an association of a single nucleotide polymorphism rs5068 in the NPPA locus gene with higher levels of circulating atrial natriuretic peptide as well as with lower intra individual blood pressure, but up to date, no association between
Entrepreneurship research has a long tradition and since the 1980s the field has grown significantly. In this study we identify the 'knowledge producers' who have shaped the field over time and their core entrepreneurship research works. A unique database consisting of all references in twelve entrepreneurship 'handbooks' (or state-of-the-art books) has been developed. The chapters in these handbo
Raptors are always considered to have an extraordinary resolving power of their eyes (high visual acuity). Nevertheless, raptors differ in their diet and foraging tactics, which could lead to large differences in visual acuity. The visual acuity of an opportunist bird of prey, the Chimango caracara (Mivalgo chimango) was estimated by operant conditioning. Three birds were trained to discriminate t
Background: A common trend in the research on 2nd generation bioethanol is the focus on intensifying the process and increasing the concentration of water insoluble solids (WIS) throughout the process. However, increasing the WIS content is not without problems. For example, the viscosity of pretreated lignocellulosic materials is known to increase drastically with increasing WIS content. Further,
The nucleus Kr-74 has been populated in the Ca-40(Ca-40,2p alpha)Kr-74 fusion-evaporation reaction at a beam energy of 165 MeV and studied using the Gammasphere and Microball multidetector arrays. The lifetimes for low-spin states in the ground-state and two signature-split negative-parity bands were determined using the Doppler-shift attenuation method. These results are discussed together with t
The key question answered by this study is whether it is possible to deliver a pharmacokinetic and pharmacodynamic duration of antidiuretic action long enough to ensure adequate antidiuresis with two daily administrations of desmopressin in patients with central diabetes insipidus (CDI). We studied the efficacy and safety of desmopressin i.v. in 13 CDI patients using two 3-way crossover designs, i
I denna artikel analyserar muntligt gestaltade erfarenheter hos före detta lägerfångar som placerades i koncentrationsläger i början av kriget i Bosnien och Hercegovina under 1990-talet. Artikeln bygger på 13 intervjuer med före detta lägerfångar och nära anhöriga som numera bor i Sverige, Danmark och Norge. Syftet med artikeln är att beskriva de sociala interaktionsritualer som återberättas efterIn this article portrayed experiences of former inmates that were placed in the concentration camps in the beginning of the war in Bosnia and Herzegovina in the 1900s are being analyzed. The article is based on 13 interviews with former inmates and close relatives that currently live in Sweden, Denmark and Norway. The purpose with the article is to describe the social interaction rituals that are
Popular Abstract in Swedish Akrylatallergi Plastmaterial består av stora molekyler som kallas polymerer samt tillsatsämnen som tillsätts för att modifiera materialets egenskaper. Polymerer bildas när det sker en stegvis reaktion mellan monomerer så att större molekyler bildas. Allergiframkallande ämnen i plastsystem kan vara monomererna, härdarna, modifierarna eller andra tillsatsämnen. AkrylaterAcrylate contact allergy has been frequently reported since the 1970s, with hundreds of articles published in dermatology journals so far. The purpose of this thesis was to investigate the frequency of contact allergy to acrylates / methacrylates in patients with exposure to industrial, dental and nail uses of these substances. We also aimed to investigate the clinical and chemical aspects of pa
Background: The Ethiopian epidemic is currently on the wane. However, the situation for infected children is in some ways lagging behind due to low treatment coverage and deficient prevention of mother-to-child transmission. Too few studies have examined HIV infected children presenting to care in low-income countries in general. Considering the presence of local variations in the nature of the ep
Objective: To assess the prevalence and risk factors of emergency peripartum hysterectomy. Design:Nordic collaborative study. Population605362 deliveries across the five Nordic countries. Methods: We collected data prospectively from patients undergoing emergency peripartum hysterectomy within 7days of delivery from medical birth registers and hospital discharge registers. Control populations cons
The production of heavy-salted cod (Bacalao) has changed from being a single-step process (kench) salting to a multistep procedure varying between producers and countries. Presalting by injection, brining, or pickling is increasingly applied prior to pile (dry) salting. This article describes the effects of different presalting methods (injection and brining, brining only, and pickling) on yield a
