Popular Abstract in Swedish Frågorna som partikelfysiker ställer är samma frågorna som folk har ställt under hela mänsklighetens tid på jorden, nämligen: Var kommer vi från? Vad är det som bygger upp det universum som vi ser? Hur håller allting ihop? Fysiker, historiens stora tänkare och hobbyfilosofen i pubben har alla funderat över de här frågorna (vissa mer än andra). Partikelfysiker försöker hAn introduction into the theory and experimental background of particle physics and the ATLAS detector is given. The transition radiation tracker (TRT) which is vital to the particle tracking and identification is then described giving particular creedence to the calibration. The automation of this calibration is explained. The second half of this thesis and the central part dwells on the analyses

A numerical study has been carried out for slot jet impinging on flat and concave surfaces. Five turbulence models are employed for the predictions of these strongly strained turbulent flows, namely linear eddy viscosity model (LEVM), low-Re explicit algebraic Reynolds stress model (EASM) and three different V2F models. A bounded formulation for Cμ was also introduced to account for the better pre

We address the issue of bidder ring formation in single and multi-unit Vickrey auctions. We address this issue in a bargaining game set up under the assumption that valuation of bidders is commonly known only amongst themselves. In the single unit case, we show that the equilibrium coalition structure can only be an order preserving r-ring, that includes the winner and the top (r-1) losers. In the

Motivated by concerns about anthropogenic climate change, this thesis contributes to the better appreciation of mechanisms that would allow actors in China, foreign as well as Chinese, to exert a positive influence on the country's industrial technology status. China is the world's second largest emitter of greenhouse gases - the lions' share of which emanates from industrial and electricity produ

Popular Abstract in Swedish Under 1990-talet genomfördes en genomgripande reform av det svenska gymnasiet. Dels ersattes de tidigare gymnasielinjerna med treåriga program, som samtliga ger en grundläggande högskolebehörighet, dels flyttades ansvaret för utbildningens genomförande och ekonomi från staten till kommunerna. Ett kriterierelaterat betygssystem ersatte också det tidigare normrelaterade. The general confidence in equal opportunity and equivalent grades are crucial to the moral justification of the social stratification in the modern society, in which meritocracy holds a hegemonic status. In Sweden, a political aim has been that everybody should get upper secondary education, and the government has established a National Agency for Education to promote and control the quality in ed

Popular Abstract in Swedish Läkning av achilles-senrupturer är idag en långdragen process, som ofta tar flera månader innan senan är fullt funktionsduglig. Syftet med studierna är att förbättra senläkningen i samband med achillesrupturer. Bone Morphogentic Proteins (BMP) är främst kända för att stimulera benläkning och bentillväxt. De lokala förhållandena har dock visat sig ha stor betydelse för cWe wanted to improve tendon healing by adding a growth factor. Bone Morphogenetic Proteins (BMPs) are well known to stimulate bone healing and bone formation. The local environment is of major importance for cell differentiation after a BMP has been added. Cartilage Derived Morphogenetic Proteins (CDMPs) -1, -2 and -3 (BMP 14, 13 and 12 or GDF 5, 6 and 7) form a subgroup in the BMP-family and are

Macroeconomic fluctuations affect corporations’ performance through demand and cost conditions. Incentive effects of performance-based compensation schemes for management may be weakened or biased by macroeconomic influences if management is unable to forecast macroeconomic fluctuations or unable to adjust operations in response to changes in macroeconomic conditions. In this paper we analyze the

The interest in open source is high, which also goes for enterprise resource planning (ERPs) systems. In this article, we focus on the combination of open source and ERPs, and specifically on what role open source ERPs plays in the diffusion of ERPs among small and medium sized enterprises (SMEs). To be able to explain the interest in open source ERPs, we look into challenges, about which a propri

Popular Abstract in Swedish I denna avhandling diskuteras olika aspekter av kärnreaktioner inducerade med tunga atomkärnor. En beskrivning av de experiment, detektorer och metoder som har använts återfinns tillsammans med en utförlig redogörelse av analysarbetet. De resultat som presenteras är baserade på dels experimentella data men även från simuleringar och teoretiska beräkningar. AvhandlingenThis thesis presents the research performed within two different research groups using heavy-ion induced nuclear reactions. They offer the opportunity to investigate different properties of nuclear matter. The results are based on measurements using a variety of different experimental techniques. The PHENIX experiment measured the production of deuteron and anti-deuterons at mid-rapidity in gold-
