En grön arbetstidsförkortning?
Det finns nu forskningsstöd för att arbetstidsförkortning leder till minskad miljöpåverkan. Mycket tyder till och med på att arbetstidsförkortning är en helt central del av en socialt och ekologiskt hållbar klimatpolitik. Det viktigaste sambandet är att arbetstiden påverkar ekonomins storlek, som i sin tur påverkar miljöförslitningen. Även om ekonomins storlek onekligen spelar roll menar författar
The protective effects of Lipoxin A(4) during the early phase of severe acute pancreatitis in rats
Objective. Our aim was to investigate the protective effects of a Lipoxin A(4) analogue (LXA(4)) in the early phase of acute pancreatitis in rats. Materials and methods. Severe acute pancreatitis (SAP) was induced by injection of 5% sodium taurocholate into the pancreatic duct. Rats with SAP were treated with LXA(4) (0.1 mg/kg), 10 min after the 5% sodium taurocholate injection, after which LXA(4)
Iduronic Acid in chondroitin/dermatan sulfate affects directional migration of aortic smooth muscle cells.
Aortic smooth muscle cells produce chondroitin/dermatan sulfate (CS/DS) proteoglycans that regulate extracellular matrix organization and cell behavior in normal and pathological conditions. A unique feature of CS/DS proteoglycans is the presence of iduronic acid (IdoA), catalyzed by two DS epimerases. Functional ablation of DS-epi1, the main epimerase in these cells, resulted in a major reduction
Rabi type oscillations in damped two-dimensional single electron quantum dots
We present a quantized model of a harmonically confined dot atom with inherent damping in the presence of a transverse magnetic field. The model leads to a non-Hermitian Hamiltonian in coordinate space. We have analytically studied the effects of damping on Rabi type oscillations of the system. The model explains the decoherence of Rabi oscillations in a Josephson Junction.
Optimization of O-18 measurement using NRA for studies of isotopic content in fossil meteorites
In this work, we discuss the possibility of a new approach to measuring oxygen isotope ratios in fossil meteorite samples, specifically one based on nuclear reaction analysis (NRA). Variations of oxygen ratios within meteoritic chromite grains can help to determine the type of meteorite to which the grains originally belonged. In this work, we have evaluated the possibility to use the reaction O-1
Methodology for Assessing Learning from Incidents - a Process Industry Perspective
Popular Abstract in Swedish Stora resurser används i processindustrin, och i många andra industribranscher, på att rapportera incidenter för att utnyttja erfarenheterna från dessa för att förebygga framtida incidenter – alltifrån mindre störningar till olyckor med stora konsekvenser. Det finns emellertid en hel del som tyder på att man ofta utnyttjar bara en del av hela den potential för lärande sLearning from incidents (from minor disturbances to major accidents) is considered one of the most important ways in the process industry to learn from experiences for improving safety performance. Most companies have a formal incident learning system and considerable resources are used for reporting incidents and for utilising these experiences to prevent future incidents. However, there are many
How the risk of liver cancer changes after alcohol cessation: A review and meta-analysis of the current literature
Background: It is well established that drinking alcohol raises the risk of liver cancer (hepatocellular carcinoma). However, it has not been sufficiently established as to whether or not drinking cessation subsequently reduces the risk of liver cancer and if it does reduce the risk how long it takes for this heightened risk to fall to that of never drinkers. This question is important for effecti

A monograph of the genus Placomaronea
A monograph of the genus Placomaronea is presented; all species described earlier are revised, a total of six species is recognized, and an identification key is presented. In addition to the three previously known species, P. candelarioides, P. lambii and P. mendozae, three new species are described: Placomaronea kaernefeltii is a large rosette-like species known from one locality in northernmost
Polycyclic aromatic hydrocarbon exposure, urinary mutagenicity, and DNA adducts in rubber manufacturing workers
Objectives: Several studies have suggested that genotoxic risks might still be present in the contemporary rubber manufacturing industry. Previously, we observed elevated levels of urinary mutagenicity and bladder DNA adducts in rubber workers. Presently, we investigated whether DNA adducts in peripheral blood mononuclear cells (PBMC) and/or urothelial cells may be caused by polycyclic aromatic hy

Remarkable similarities of chromosomal rearrangements between primary human breast cancers and matched distant metastases as revealed by whole-genome sequencing.
To better understand and characterize chromosomal structural variation during breast cancer progression, we enumerated chromosomal rearrangements for 11 patients by performing low-coverage whole-genome sequencing of 11 primary breast tumors and their 13 matched distant metastases. The tumor genomes harbored a median of 85 (range 18-404) rearrangements per tumor, with a median of 82 (26-310) in pri

Optical absorption of polarized light in InAs/GaSb quantum wells
Using an eight-band k . p model Hamiltonian with the Burt-Foreman envelope function theory, we have investigated the optical absorption of both linearly and circularly polarized light, as well as related phenomena in InAs/GaSb broken-gap quantum wells grown along the [0 0 1] direction, with emphasis on the effects of electron-hole hybridization and the various symmetry-breaking mechanisms such as
Immunotherapy and COX-2 inhibition against malignant brain tumors
Glioblastoma multiforme (GBM) is the most common primary brain tumor in the central nervous system and the prognosis is very poor despite conventional therapies including surgery, chemo- and radiotherapy. Peripheral vaccination with irradiated tumor cells represent a novel therapy that targets both dividing and non-dividing tumor cells and minimizes the risk of therapy resistance by presenting mul
Fermi Large Area Telescope First Source Catalog
We present a catalog of high-energy gamma-ray sources detected by the Large Area Telescope (LAT), the primary science instrument on the Fermi Gamma-ray Space Telescope (Fermi), during the first 11 months of the science phase of the mission, which began on 2008 August 4. The First Fermi-LAT catalog (1FGL) contains 1451 sources detected and characterized in the 100 MeV to 100 GeV range. Source detec

How mobile are protons in the structure of dental glass ionomer cements?
The development of dental materials with improved properties and increased longevity can save costs and minimize discomfort for patients. Due to their good biocompatibility, glass ionomer cements are an interesting restorative option. However, these cements have limited mechanical strength to survive in the challenging oral environment. Therefore, a better understanding of the structure and hydrat
Ultrasound as predictor of perinatal outcome
The aim of the work described in this thesis was to evaluate the value of ultrasound examinations of the amniotic fluid, umbilical cord and blood flow velocity waveform of the fetal and placental vessels as predictors of the perinatal outcome. In the first study, the amniotic fluid index (AFI) measured on admission to the labour ward was evaluated in low-risk pregnancies. An increased risk of ope
