Changes in ultraviolet-radiation reaching the earths surface

The quality and quantity of UV measurements have increased greatly in the last few years. Variations among measurements from different instruments are diminishing toward the 5% level. Long-term trend detection is still a problem, with little historical data available for baseline estimations. Enhanced UV levels are clearly associated with the Antarctic springtime ozone reductions. Measurements sho

Neuropathological postmortem evaluation of BNCT for GBM

Background - Thirty patients with glioblastoma multiforme (GBM) were treated by boron neutron capture therapy (BNCT) at the Studsvik facility in Sweden, in a clinical trial exploring a procedure in which 900 mg p-boronophenylalanine (BPA) per kilo body weight was infused in 6 h. Objective - The present study was designed to assess tumor efficacy and radiation damage to the brain for the seven pati

Lung transplantation at the University of Lund 1990-1995. Analysis of the first 39 consecutive patients

Between 1990 and 1995 39 patients were lung transplanted at the University Hospital in Lund. This is a retrospective review of survival and lung function in these patients. There were 17 single-lung transplants (SLT), 21 double-lung transplants (DLT) and 1 heart-lung transplant (HLT). Seven patients died during the period, giving an overall survival of 82%. One-year survival according to Kaplan-Me

Visual influence on postural control, with and without visual motion feedback.

Body sway was investigated in 20 healthy subjects to determine whether visual input must contain motion feedback information from the surroundings in order to influence postural control. Posturography was used to record body sway under the following visual conditions: eyes open with or without a restricted visual field; eyes open in ganzfield white light; eyes open in darkness with a head-fixed vi

Skadestånd som sanktion mot karteller

Abstract in Undetermined Ett hitintills outnyttjat sanktionsinstrument i den svenska konkurrenslagen är skadeståndet – en sanktion som i kartellbekämpningens ursprungsland USA intar en dominerande roll. I detta arbete har vi för avsikt att studera skadeståndets utformning och funktion i svensk och europeisk konkurrensrätt med utgångspunkt från hur det kan bidra till en effektivare kartellbekämpnin

Nitrogen-doped carbon nanotubes under electron irradiation simulated with a tight-binding model

Experiments show that nitrogen-doped carbon nanotubes subjected to the electron beam in a transmission electron microscope can easily lose dopant atoms and that overall they are less stable under electron irradiation than the pristine tubes. To understand the lower stability of nitrogen-doped nanotubes we use a density-functional-theory-based tight-binding model and simulate impacts of energetic e

Zarah Leander: Den queera divan

This article discusses the actress and singer Zarah Leander (1907-1981), one of the most celebrated female stars in German Nazi Cinema 1936-43. She is a contradictory figure, and her star persona has always been a negotiation of antagonistic formulations, thus pointing to modes of audience identification and specatorship issues, most strikingly articulated through her immense popularity in the pos

Measurement and QCD analysis of the diffractive deep-inelastic scattering cross section at HERA

A detailed analysis is presented of the diffractive deep-inelastic scattering process ep -> eXY, where Y is a proton or a low mass proton excitation carrying a fraction 1 - x(IP) > 0.95 of the incident proton longitudinal momentum and the squared four-momentum transfer at the proton vertex satisfies |t| < 1 GeV2. Using data taken by the H1 experiment, the cross section is measured for photon virtu

Rotational Bands with Terminating Properties in 59Ni

Highly-deformed rotational bands were established in Ni-59 using the Ca-40(Si-29,2p2alpha)Ni-59 reaction. Lifetime measurements indicate that transition quadrupole moments of two of these bands decrease as they smoothly approach their maximum-spin states. The configurations of these bands as well as their band-terminating features are discussed based on configuration-dependent cranked Nilsson-Stru

Comparison of growth characteristics and exopolysaccharide formation of two lactic acid bacteria strains, Pediococcus damnosus 2.6 and Lactobacillus brevis G-77, in an oat-based, non-dairy medium.

The fermentation characteristics of two strains of lactic acid bacteria (LAB), Lactobacillus brevis G-77 and Pediococcus damnosus 2.6 were compared in an oat-based, nondairy milk medium (Adavena® G40). Viscosity and ropiness were the main growth parameters studied. Both strains are reported to produce an exopolysaccharide (EPS) with a -glucan structure; in addition, the L. brevis strain produces a

Multimodal approach to seismic pavement testing

A multimodal approach to nondestructive seismic pavement testing is described. The presented approach is based on multichannel analysis of all types of seismic waves propagating along the surface of the pavement. The multichannel data acquisition method is replaced by multichannel simulation with one receiver. This method uses only one accelerometer-receiver and a light hammer-source, to generate

Adverse effects and benefits of two years of anagrelide treatment for thrombocythemia in chronic myeloproliferative disorders

Background and Objectives. Although anagrelide is widely used in the treatment of throm-bocythemia in myeloproliferative diseases, there is currently limited information on the efficacy and toxicity of its long-term use. This prospective study investigated clinical toxicity and efficacy of anagrelide during two years of treatment. Design and Methods. A multicenter, open, phase II study of anagreli

Development of monoclonal antibodies against creatine kinase MB2

An increase of creatine kinase MB (CKMB) in serum has long been used as a marker for acute myocardial infarction (AMI). It is important with an early diagnosis and since the amount of the CKMB2 isoform rises above reference levels much earlier than the total creatine kinase amount, quantification of CKMB isoforms could be a feasible alternative for early analysis. The two CKMB isoforms differ by o
