The production of pi(+), pi(-), K+, K-, p, and (p) over bar at mid-rapidity has been measured in proton-proton collisions at root s = 900 GeV with the ALICE detector. Particle identification is performed using the specific energy loss in the inner tracking silicon detector and the time projection chamber. In addition, time-of-flight information is used to identify hadrons at higher momenta. Finall
Popular Abstract in Swedish När vi äter socker frisätter kroppen hormonet insulin från specifika beta-celler i bukspottskörteln för att förmå muskelceller och fettceller att ta upp sockret från blodet och därmed återställa blodets sockerbalans. Vid övervikt blir dessa vävnader resistenta mot insulinets verkan vilket leder till att sockret stannar kvar i blodet. Detta vill kroppen undvika då en förThere are many contributing factors to the development of type 2 diabetes, however, failure of beta-cells to sufficiently secrete insulin is the key component. The underlying mechanism of beta-cell failure is not fully established. In this thesis, we examined the role of high glucagon levels, i.e. hyperglucagonemia, for the development of beta-cell dysfunction in pre-diabetic mice. We found that i
Oxidative stress has been implicated as an important factor in the progression of many diseases. An imbalance in the redox-system may cause oxidation of cells and molecules, which might subsequently lead to tissue damage. The research presented in this thesis has focused on elucidating a possible involvement of the human protein alpha-1-microglobulin in the defence against pathological oxidation.
Molecular weight (MW) is one of the most important characteristics of macromolecules. Sometimes, MW cannot be measured correctly by conventional methods like gel permeation chromatography (GPC) due to, for example, aggregation. We propose using single-molecule spectroscopy to measure the average MW simply by counting individual fluorescent molecules embedded in a thin matrix film at known mass con
Using genome-wide association, we identify common variants at 2p12-p13, 6q26, 17q23 and 19q13 associated with serum creatinine, a marker of kidney function (P = 10(-10) to 10(-15)). Of these, rs10206899 (near NAT8, 2p12-p13) and rs4805834 (near SLC7A9, 19q13) were also associated with chronic kidney disease (P = 5.0 x 10(-5) and P = 3.6 x 10(-4), respectively). Our findings provide insight into me
The polemics of Solomon Adret, Bahya ben Asher, and Abraham Bibago are presented, based on my book: Shield and Sword. 1993.
OBJECTIVE: To elucidate parent´s experience of having had a baby with colic four years previously and of how the colic and care influenced the family in a long-term perspective. METHODOLOGY AND PARTICIPANTS: A qualitative inductive follow-up study with 13 individual and one focus group interview including four parents. Altogether ten mothers and seven fathers representing 12 families, who had been
A measurement of W boson production in lead-lead collisions at root s(NN) = 2.76 TeV is presented. It is based on the analysis of data collected with the ATLAS detector at the LHC in 2011 corresponding to an integrated luminosity of 0.14 nb(-1) and 0.15 nb(-1) in the muon and electron decay channels, respectively. The differential production yields and lepton charge asymmetry are each measured as
Despite a history of conflicts and widespread human rights violation in sub-Saharan Africa, little is known about the prevalence of interpersonal violence among the population in this region. Evidence from high-income countries suggests that exposure to violence has mental health consequences and violence also has associations with experiences of sexual coercion.

Introduction: Studies have shown that executive dysfunction is common in adults after stroke. Occupational therapists working in acute care assess the performance of activities of daily living; most instruments focus on personal care. However, the assessment of instrumental activities of daily living has been shown to discriminate executive dysfunction more effectively. An instrument for assessing
The nature of size fluctuations is crucial in forecasting future population persistence, independently of whether the variability stems from external forces or from the dynamics of the population renewal process. The risk of intercepting zero is highly dependent on the way the variance of the population size relates to its mean. The minimum population size required for a population not to go extin
Manipulation tasks are characterized by continuous motion trajectories containing a set of key phases. In this paper, we propose a probabilistic method to autonomously segment the motion trajectories for estimating the key phases embedded in such a task. The autonomous segmentation process relies on principal component analysis to adaptively project into one of the low-dimensional subspaces, in wh
Flying animals are capable of navigating through environments of different complexity with high precision. To control their flight when negotiating narrow tunnels, bees and birds use the magnitude of apparent image motion (known as optic flow) generated by the walls. In their natural habitat, however, these animals would encounter both cluttered and open environments. Here, we investigate how larg
The maintenance of steam turbines is expensive, particularly if dismantling is required. A concept for the provision Of Support for the maintenance engineer in determining steam turbine status in relation to the recommended maintenance interval is presented here. The concept embodies an artificial neural network which is conditioned to recognise patterns known to be related to faults. The faults S
We analyse the rate of formation, the characteristics, and the performance of different types of new firms in Sweden over a decade. Comparisons with Denmark, Brazil, and the United States suggest that the environment for new firm formation in Sweden is not markedly different than elsewhere. In line with previous studies, spin-offs of incumbents perform better than other types of new firms, particu
Studies on dissolved silicate (DSi) and biogenic silica (BSi) dynamics were carried out in the Oder estuary, Baltic Sea in 2000-2005. The Oder estuary proved to be an important component of the Oder River-Baltic Sea continuum where very intensive seasonal DSi uptake during spring and autumn, but also BSi regeneration during summer take place. Owing to the regeneration process annual DSi patterns i
Introduction: All bird eggs are exposed to microbes in the environment, which if transmitted to the developing embryo, could cause hatching failure. However, the risk of trans-shell infection varies with environmental conditions and is higher for eggs laid in wetter environments. This might relate to generally higher microbial abundances and diversity in more humid environments, including on the s
