Systematic studies of global observables in PHENIX

Systematic studies of global observables in different collision systems are indispensable for mapping the QCD phase diagram. Fluctuations in these quantities can provide fundamental information relevant for the phase transitions. The following global observables relevant to critical behavior are studied: the longitudinal density correlation, K to π and p to π fluctuations, and the constituent quar

Möteskultur i ungdomsvården

I denna artikel analyseras möteskulturer och mötesstrider mellan olika professionella i ungdomsvården, samt det starka engagemang som ägnas åt dessa möten. Artikeln bygger på en studie av ett samverkansprojekt i ungdomsvården där ett antal samordnare anställdes. Det visade sig att dessa efter hand kom att upprätthålla en administrativ hållning gentemot varandra, vilket satte det direkt arbetet medThis article concerns a large evaluation of a project concerning Swedish juvenile care. The project were set up as a “care-chain” involving various authorities, and a number of coordinators were employed to facilitate youngsters’ “after-care” when they had left the special approved homes of The National Board of Institutional Care. Even though the original goals of the project stated that the coor

Crop Yield Gaps in Cameroon

Although food crop yields per hectare have generally been increasing in Cameroon since 1961, the food price crisis of 2008 and the ensuing social unrest and fatalities raised concerns about the country's ability to meet the food needs of its population. This study examines the country's potential for increasing crop yields and food production to meet this food security challenge. Fuzzy set theory

Robust Subspace-based Fundamental Frequency Estimation

The problem of fundamental frequency estimation is considered in the context of signals where the frequencies of the harmonics are not exact integer multiples of a fundamental frequency. This frequently occurs in audio signals produced by, for example, stiff-stringed musical instruments, and is sometimes referred to as inharmonicity. We derive a novel robust method based on the subspace orthogonal

Search for light top squark pair production in final states with leptons and b-jets with the ATLAS detector in root s=7 TeV proton-proton collisions

The results of a search for pair production of light top squarks are presented, using 4.7 fb(-1) of root s = 7 TeV proton-proton collisions collected with the ATLAS detector at the Large Hadron Collider. This search targets top squarks with masses similar to, or lighter than, the top quark mass. Final states containing exclusively one or two leptons (e, mu), large missing transverse momentum, ligh

Rac1 signaling regulates platelet-dependent inflammation abdominal sepsis

Popular Abstract in Swedish Sepsis, blodförgiftning är en systemisk inflammatorisk reaktion syndrom vid en lokal eller systemisk infektion som leder till överproduktion av proinflammatoriska cytokiner och det ultimata misslyckandet av flera organsystem. Sepsis är ett potentiellt allvarligt och komplicerat kliniskt syndrom samt är en av de vanligaste orsakerna till döden på intensivvårdsavdelningarSepsis is a systemic inflammatory response syndrome to a localized or systemic infection that leads to the over production of proinflammatory cytokines and the ultimate failure of multiple organ systems. However, little is known about the potential role of Rac1 in controlling sepsis-induced intracellular signaling pathways. We hypothesized that Rac1 might be involved in sepsis mediated signaling p

Structural investigation of GaInP nanowires using X-ray diffraction

In this work the structure of ternary GaxIn1-xP nanowires is investigated with respect to the chemical composition and homogeneity. The nanowires were grown by metal-organic vapor-phase epitaxy. For the investigation of ensemble fluctuations on several lateral length scales, X-ray diffraction reciprocal space maps have been analyzed. The data reveal a complicated varying materials composition acro

Moisture conditions in rain exposed wood joints - Experimental methods and laboratory measurements

Denna studie behandlar fuktförhållandena i regnexponerade träkonstruktioner, d.v.s. träkonstruktioner som når höga fuktkvoter. Särskilt fokus var på mikroklimatet (klimatet på träets yta) och materialklimatet (träets fuktkvot) i anslutningar. Metoder för att mäta mikroklimatet, d.v.s. våttider på en träyta och varaktighet av vatten i spalter, utvecklades liksom en metod för att mäta fuktkvot nära This thesis concerns the moisture conditions in rain exposed wood structures, i.e. wood exposed to high moisture levels. The focus was on the microclimate (the climate at the wood surface) and the material climate (the wood moisture content) in joints. Methods for determination of microclimate, i.e. the duration of moisture on a wooden surface and the duration of water trapped in gaps between two

Measurement of the t-channel single top-quark production cross section in pp collisions at root s=7 TeV with the ATLAS detector

We report a measurement of the cross section of single top-quark production in the t-channel using 1.04 fb(-1) of pp collision data at root s = 7 TeV recorded with the ATLAS detector at the LHC. Selected events feature one electron or muon, missing transverse momentum, and two or three jets, exactly one of them identified as originating from a b quark. The cross section is measured by fitting the

Controller reduction via minimum rank matrix approximation

In this paper a controller reduction method for discrete-time linear time-invariant systems is described. Using the bounded-real lemma, the proposed method generates reduced controllers with closed loop stability and H-infinity norm performance guarantee. Information of the full controller is used as a basis for reduction using singular value decomposition. This is different from traditional model

Tillbaka till texten. Derivativt skrivande i en svensk gymnasieklass

This licentiate thesis investigates fiction writing and reading in up- per secondary school in Sweden. Inspired by fanfiction I created a teaching project of derivative writing in which the students in a se- cond-year social science class wrote short stories derived from 20th century novels. They also gave peer response, both orally and in writing. Finally they wrote a reflective text about the pr

Practical and physiological aspects of breath alcohol analysis

Breath alcohol analysis constitutes sufficient material for the prosecution of drunk driving without the need for blood analysis. However, the prevailing method used for breath analysis lacks standardization of several physiological variables that cause a variation of the breath alcohol concentration (BrAC). In this thesis, a novel analyzer which standardizes the BrAC to the water vapour concentra

Health-Related Quality of Life and Adherence in Haemophilia

Assessment of health-related quality of life (HRQoL) in haemophilia is important in order to provide information for clinical decision making and to verify the impact of haemophilia on patients and their families. Advances in haemophilia care and prophylactic treatment have improved HRQoL for the patients and where treatment is available, patients with haemophilia have almost reached the same life

The FLT3 inhibitor PKC412 in combination with cytostatic drugs in vitro in acute myeloid leukemia

An internal tandem duplication of FLT3 (FLT3/ITD) occurs in approximately 25% of newly diagnosed AML. PKC412 inhibits the growth of leukemic cell lines with FLT3 mutations such as the MV4-11. This study evaluated the in vitro effects of the combination of PKC412 and ara-C or daunorubicin, studying the effect of co-incubation, pre-incubation and sequential incubation of the drugs in patient samples
