A search is presented for dark matter pair production in association with a W or Z boson in pp collisions representing 20.3 fb(-1) of integrated luminosity at root s = 8 TeV using data recorded with the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet with the jet mass consistent with a W or Z boson, and with large missing transverse momentum are analyzed. The data are consi

Background Utilizing surgical services, including caesarean sections, can result in catastrophic expenditure and impoverishment. In 2010, Sierra Leone introduced the Free Health Care Initiative (FHCI), a national financial risk protection program for the most vulnerable groups. Aim of this study was to investigate catastrophic expenditure and impoverishment related to caesarean section in Sierra L

The ratio of production cross sections of the W and Z bosons with exactly one associated jet is presented as a function of jet transverse momentum threshold. The measurement has been designed to maximise cancellation of experimental and theoretical uncertainties, and is reported both within a particle-level kinematic range corresponding to the detector acceptance and as a total cross-section ratio

In an attempt to study further the age-specific influence on the hypothalamo-pituitary-gonadal axis as well as the hypothalamo-pituitary-thyroid axis, we have now investigated young and middle-aged men, considering possible confounding factors. Both serum total testosterone, free testosterone and the total ratio of testosterone to sex-hormone binding globulin were significantly lower among middle-

Within the FLASH2020+ upgrade, the pump-probe laser capabilities of the extreme ultraviolet and soft x-ray free-electron laser (XFEL) FLASH in Hamburg will be extended. In particular, providing wavelength tunability, shorter pulse durations, and reduced arrival time jitter will increase the scientific opportunities and the time resolution for the XFEL-optical laser pump-probe experiments. We prese

Intensive insulin therapy, aiming for strict normoglycaemia, is associated with increased survival in critically ill patients. Insulin therapy concomitantly reduces plasma-free fatty acids. Recent studies indicate that free fatty acids mediate inflammation. In addition to plasma glucose and free fatty acid-lowering effects, insulin also has anti-inflammatory properties. This study was designed to

Popular Abstract in Swedish Svensk sammanfattning Slaganfall (stroke), hjärtstillestånd eller överdosering av insulin är tillstånd som leder till en minskning av syre- och/eller glukos till hjärnvävnaden. Då tillförseln av glukos och syrgas minskar, kan cellerna inte längre upprätthålla en normal energiproduktion. Eftersom en stor del av energin går åt till bevara den spänning som finns över cellIn this thesis mechanisms of neuronal damage were investigated in an experimental stroke model i.e focal ischemia. The influence of SD-induced calcium transients on neuronal damage were studied in animals with reduced energy supply. The influence of bioenergetic failure on K+e concentration and Ca2+e homeostasis were also investigated in transient focal ischemia. Moreover, the free radical formati

Nonintrusive methods for characterizing food products are of increasing interest related to the greater awareness of food safety issues. Hen eggs are an important part in food consumption in most parts of the world. We have investigated an optical method utilizing tunable diode lasers for monitoring free gas in eggs. We show that oxygen signals, recorded around 760nm, increase steadily as eggs bec

In hereditary Huntington's disease, a triplet repeat disease, there is extensive loss of striatal neurons. It has been shown that brain-derived neurotrophic factor (BDNF) protects striatal neurons against a variety of insults. We confirmed that BDNF enhances survival and DARPP-32 expression in primary striatal cultures derived from postnatal mice. Furthermore, BDNF inhibited intracellular oxyradic

This Master’s thesis examines the outcomes of the new Free Choice policy with particular emphasis on whether giving residents the right to choose their providers of primary health care leads to a more equal distribution of primary health care accessibility. This study is based on the Secondary Analysis of assessment for vårdval (choice of health system) in Stockholm by Karolinska Institute (2010),

Art. 36 TFEU is an exception clause which provides that quantitative restrictions or measures having equivalent effect to quantitative restrictions falling under Art. 34 and 35 TFEU may be justified under certain circumstances. If a national measure can be considered liable to hindering the trade between Member States, the national measure can be justified by one of the derogations listed in Art.
