We show that the hard qq̄ production is very sensitive to the details of the parton shower and that our treatment based on the dipole approximation gives significantly larger production than “conventional” parton showers. For our model we find qualitative agreement with experimental data for the Kπ ratio and D-meson production in high-pT jets.
We have searched for direct photons of low PT (≤1.0 GeV/c) at θc.m.=90° in pp collisions at √s =63 GeV. We used two independent methods: direct detection in NaI crystals and conversion to e+e− pairs. No signal is observed; the photon spectrum is well described by the decay of hadrons. The result is consistent with a direct low-PT photon signal reported at √s =12 GeV, but excludes a rapid growth of
We present a method to implement the gluon splitting process, g → QQ, into the dipole approximation to QCD cascades. It is known that due to the uncertainties in the interpolation between the pole regions, there are large uncertainties in the results. We show that there are further uncertainties due to the ordering in phase space of the gluon emission and gluon splitting processes. We present two
The migration of the great snipe Gallinago media was previously poorly known. Three tracks in 2010 suggested a remarkable migratory behaviour including long and fast overland non-stop flights. Here we present the migration pattern of Swedish male great snipes, based on 19 individuals tracked by light-level geolocators in four different years. About half of the birds made stopover(s) in northern Eu
We present a framework for deep inelastic scattering, with bound state properties in accordance with a QCD force field acting like a vortex line in a colour superconducting vacuum, which implies some simple coherence effects. Within this scheme one may describe the results of present energies very well, but one obtains an appreciable depletion of gluon radiation in the HERA energy regime.
Biomass is becoming particularly important as a starting material for advanced carbon structures. In this study, we found interesting nanostructures on the surface of burnt spaghetti using scanning electron microscopy, transmission electron microscopy (TEM), and energy dispersive X-ray spectroscopy (EDX) for analysis. The structures were elongated and finger-like, with evidence that the tubes have
In the master narrative of rape some women’s testimonies of sexual violence become particularly tainted with doubt and disbelief. Conversely, only some men’s sexually violent acts are unconditionally marked by guilt and blame. The chapter stresses the spatial dimension of this master narrative of rape. With an analysis of two hyper-medialised Swedish gang rape cases, it is highlighted how a moral
Objective: Epidemiologic data indicate decreased risk for development, growth, and rupture of abdominal aortic aneurysm (AAA) among patients with type 2 diabetes mellitus (DM). We therefore evaluated mortality and cardiovascular morbidity after acute repair of AAA in diabetic and nondiabetic patients. Methods: In this nationwide observational cohort study of patients registered in the Swedish Vasc
Författaren har i en tidigare artikel diskuterat Högsta domstolens praxis avseende bevisbördans placering i fordringsmål med utgångspunkt i rättsfallen ”Tandläkarens olycka” (NJA 2014 s. 364) och ”Terrys Restaurang” (NJA 2017 s. 1094). I artikeln presenteras bl.a. två alternativa tolkningar av rättsfallet ”Tandläkarens olycka”. Den 6 februari i år meddelade Högsta domstolen dom i NJA 2019 s. 23, ”
On 1 July 2018, a new consent-based legislation entered in force in Sweden, making it illegal to perform sexual intercourse with a person who was not participating voluntarily. The main argument in this chapter is that in Sweden, this legal shift was the result of a discursive process that since the mid-1990s, in particular, was taking place in news reports and debate about the legal handling of a
This article examines six multilingual students’ composing processes and language use while writing in L2 English. Four participants have two L1s: Swedish and either Bosnian (N = 2) or Macedonian (N = 2). The remaining two participants have Swedish as their L1. Building on an L2 composing model (Wang and Wen, 2002) and the theory of Language Mode (Grosjean, 2008), the study uses think-aloud data t
A capacitive sensor was developed to analyze the presence and enzymatic activity of a model protease from standard solutions by following the degradation of the substrate in real time. The enzyme was chosen based on its specific digestion of the hinge region of immunoglobulin G (IgG). Real-time enzyme activity was monitored by measuring the change in capacitance (∆C) based on the release of IgG fr

Burkholderia are opportunistic pathogens. Here we describe a case of Burkholderia multivorans urinary tract infection in a previously healthy man. The bacterium was likely introduced during sexual intercourse in a home hot tub contaminated with the bacterium. The infection led to urinary retention and was successfully treated with trimethoprim-sulfamethoxazole.
Typhoon Haiyan damaged around a million houses in the Philippines in November 2013. It especially affected the poor. Using a realist laminated ontology, this paper explains how multiple causal mechanisms triggered unexpected outcomes in the housing recovery programme in the province of Leyte. The proposed causal mechanisms were: the intentional causal agency of the Filipino power elite; the collab
BACKGROUND: Lipopolysaccharide (endotoxin) from the outer Gram-negative bacterial wall can induce a harmful immunologic response, involving hemodynamic deprivation, and is one important motor driving the septic cascade. The positively charged poly-imine ethylene layer on the oXiris membrane is capable of adsorbing negatively charged endotoxin molecules and removing them from the blood compartment.
