The beams extracted from thermal neutron sources such as nuclear reactors are monochromatised by Bragg diffraction using imperfect single crystals with an angular mosaic spread of typically 0.2-0.8 degrees. For neutron wavelengths below 1.5 angstrom, the highest reflectivity of all crystalline materials is expected for diamond. Nowadays diamond single crystals with an appropriate mosaic spread exc

Background: Renal disease remains a serious threat in patients with insulin-dependent (type1) diabetes. Hence its detection early in the life of patients with type1 diabetes is crucial. Several lines of evidence suggest similar mechanisms for the development of both renal and arterial disease. We sought to investigate in young patients with type1 diabetes whether pi-Glutathione S-transferase to cr

I Doktorandbarometern 2007 har över 700 doktorander vid Lunds universitet bidragit med sina erfarenheter av forskarutbildningen. En väsentlig del av dessa erfarenheter var gemensamma, trots att de representerade olika vetenskapsområden. Ett annat intressant resultat visade på betydelsen av doktoranders delaktighet och medarbetarskap i forskarutbildningsmiljön. De som huvudsakligen arbetade inom ra

Industrial fermentation of lignocellulosic hydrolysates to ethanol requires microorganisms able to utilise a broad range of carbon sources and generate ethanol at high yield and productivity. D. bruxellensis has recently been reported to contaminate commercial ethanol processes, where it competes with Saccharomyces cerevisiae [4, 26]. In this work Brettanomyces/Dekkera yeasts were studied to explo

A Monte Carlo method is employed to calculate the dynamical conductivity in the terahertz range of free charge carriers localized in semiconductor nanoparticles. The shape of the conductivity spectrum is essentially determined by the probability of carrier transition through interparticle boundaries and by the ratio of the nanoparticle size and carrier mean free path in the bulk. It is shown that

Background and Purpose-Secondary prevention is recommended after stroke, but adherence to guidelines is unknown. We studied the prescription of antiplatelet drugs, angiotensin-converting enzyme inhibitors, statins, and anticoagulant drugs and their relation to risk of death. Methods-Patients with first-ever ischemic stroke in 2005 were registered in the Swedish Stroke Register. Odds ratios, hazard

Cardiac rhabdonnyomas are rare and often regress spontaneously. However, the management of rhabdomyoma with severe inflow and outflow obstructions is a challenge. An infant with a massive left ventricular rhabdomyoma mimicking the haemodynamics of hypoplastic left heart syndrome is reported. Surgery could not be contemplated because the mitral valve leaflets and chordae were imbedded in the tumour

Clothing evaporative resistance is an important input in thermal comfort models. Thermal manikin tests give the most accurate and reliable evaporative resistance values for clothing. The calculation methods of clothing evaporative resistance require the sweating skin surface temperature (i.e., options 1 and 2). However, prevailing calculation methods of clothing evaporative resistance (i.e., optio

Sensitive temperature-induced line shifts of the near-band-edge emission from ZnO:Ga and ZnO:Zn are investigated for two-dimensional (2D) thermometry with nanosecond time resolution. Spectral and temporal concerns for 2D measurements and the feasibility for utilizing the line shifts for temperature measurements using a spectral ratio are investigated. Owing to the high temperature sensitivity, a p

Let's do the twist: The first twisted bis-amide is obtained by the benzylic oxidation of Tröger's base (TB). Kinetic studies of its acidic hydrolysis reveal that the hydrolysis is to a large extent funneled through doubly protonated species.

Objective. The authors aimed to investigate the incidence and outcomes of acute upper gastrointestinal bleeding (AUGIB) and to examine the role of drugs potentially associated with AUGIB. Methods. The study was prospective, population-based and consisted of all patients who underwent upper gastrointestinal endoscopy (UGE), during the year of 2010 at the National University Hospital of Iceland. Dru

Aims To study various aspects of treatment for retinopathy of prematurity (ROP) in a Swedish population of extremely preterm infants born before 27 weeks of gestation. Methods A national, prospective and population-based study was performed in Sweden from 1 April 2004 to 31 March 2007. The criteria for the treatment of ROP accorded with the recommendations of the Early Treatment for Retinopathy of

Studies in experimental autoimmune encephalomyelitis (EAE), a mouse model of multiple sclerosis, have shown that B cells markedly influence the course of the disease, although whether their effects are protective or pathological is a matter of debate. EndoS hydrolysis of the IgG glycan has profound effects on IgG effector functions, such as complement activation and Fc receptor binding, suggesting
