En utveckling av den s. k. väte-ekonomin, där vätgas (H2) används som energibärare, skulle – rent teoretiskt – kunna lösa människans energiproblem då vatten skulle kunna användas som bränsle. För att nå detta mål krävs dock väsentlig teknologisk och vetenskaplig utveckling. Ur ett rent vetenskapligt perspektiv, måste bl a (energisnåla) kemiska metoder att skapa stora mängder vätgas utvecklas. MångAbstract – The mixed-valence triiron complexes [Fe3(CO)7-x(PPh3)x(µ-edt)2] (x = 0, 1, 2; edt = SCH2CH2S) and [Fe3(CO)5(κ2-diphosphine)(µ-edt)2] (diphosphine = dppv, dppe, dppb, dppn) have been prepared and structurally characterized. In comparison to the diiron complex [Fe2(CO)6(µ-edt)], [Fe3(CO)7(µ-edt)2] catalyzes proton reduction at 0.36 V less negative potentials, which is a significant energe

The Transfermium Working Group (TWG) was set up in 1986 under the joint auspices of the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP). Its conclusions, duly endorsed by IUPAC and IUPAP, were published in the following three reports: 1.

Denna sammanläggningsavhandling består av fyra artiklar, som alla berör olika utvidgningar av Standardmodellen (SM). De första två artiklarna behandlar en specifik, supersymmetrisk, storförenad teori (GUT), medan de senare två klassificerar alla anomali-fria instanser av 2-Higgs-dubblett modeller (2HDMs) med en gauge:ad abelsk symmetri. Artikel I. I denna artikel presenterar vi en alternativ lösniThis thesis is composed of four papers, which all treat various extensions to the Standard Model (SM). The first two papers concern a particular supersymmetric, grand-unified theory (GUT), while in the latter two, we classify anomaly-free implementations of two-Higgs doublet models (2HDM) with a gauged abelian symmetry. Paper I. In this paper, we present an alternative solution for avoiding GU

This thesis concerns two languages in contact: English and Swedish. It is based on interviews with Swedes who came to North America with the last major wave of emigration. The bilingual phenomena that appear in their speech, ranging from codeswitching to morphological, structural and semantic transfer, are considered as forming a continuum of language alternation. The study explores the opposing

Zinc status was evaluated in 30 subjects with Crohn's disease. Intestinal resection had previously been performed in 23 of the subjects. The concentrations of zinc were determined in plasma, erythrocytes, percutaneous muscle biopsies, and in urine collected during 24 hours. The results were compared with those in 19 healthy controls. Most of the patients had a normal zinc status. The levels of zinZinc status was evaluated in 30 subjects with Crohn's disease.

At the intersection between industrial relations and corporate governance - i.e. board level worker representation - this paper attempts to bridge four perspectives from the industrial relations literature (unitary, pluralist, radical and egoist) by observing changes in board director perceptions over time. Empirically, a longitudinal survey (1994-2014), filled out by both shareholder- and worker-

The newly developed website ’Den botaniska skattkammaren’ [The botanic treasury; www.botskatt.se] is presented. It is intended to be gradually filled with miscellaneous information about vascular plant taxa found in, or expected to be found in Swedish nature (i.e. including all kinds of ephemerals and garden escapes). The material included will partly be newly produced, partly reproduced with perm

Recent qualitative and quantitative research on the interrelationships between innovation, job quality and employment shows a strong association between job quality and product, process, and to a lesser extent organizational innovation. This is theorized as the interaction of two systems – job quality and innovation systems. Increased employment and improved job quality are found to result from inRecent qualitative and quantitative research on the interrelationships between innovation, job quality and employment shows a strong association between job quality and product, process, and to a lesser extent organizational innovation.

Uppsatsens syfte är att identifiera kritiska framgångsfaktorer inom Internetpokerbranschen för att öka förmågan att analysera framtidsutsikterna i branschen. För att uppnå syftet utarbetas en branschanalysmodell som tar hänsyn till den dynamik som existerar i pokerbranschen. I uppsatsen används en kvalitativ metod och ett abduktivt angreppssätt. Det genomförs intervjuer med två Internetpokerföreta

This research aims at studying continuous time models within different stock market environments. We assume that the modeling of continuous time processes may be altered whether an equity market is experiencing a crisis or a pre-crisis period. As a benchmark index, the S&P500 has been chosen for this study and the sampling periods in question include the Black Monday of 1987, the Dot-Com of 20

Majoriteten av dagens moderna organisationer har implementerat någon form av informations- och kommunikationsteknik (IKT) i sin verksamhet. Många ideella organisationer tillämpar också denna teknik, dock skiljer sig förutsättningarna för dessa organisationer. Eftersom IKT är en kostsam investering är det av vikt att det leder till önskade effekter. Flera olika faktorer påverkar användandet och eff

In the literature on democracy, the media is often recognized as a fundamental pillar. Doubtlessly, a healthy democratic society requires an actively ongoing and informed public debate on matters of significance. Recognizing that we are to some extent dependent on the news media for our understanding of the world around us, this thesis sets out to study how the Swedish nation-wide news media perfo

Som svar på behovet av flexibla utbildningar och i takt med den tekniska utvecklingen har interaktiva d.v.s. datorbaserade utbildningar uppkommit inom flertalet ämnen så också i språk. Vi är mycket nyfikna på den här nya formen av språkutbildning och kan tänka oss att pedagogiska aspekter har mycket att tillföra utvecklingen. Syftet med uppsatsen är att visa hur interaktiva språkutbildningar kan v

This thesis aims to investigate a case of worker’s direct action against distilleries of hard liquor (brännvin) in the southern Swedish town of Karlshamn, November 1853. Many people were angry because the distilleries were allowed to keep on distilling grains and potatoes despite the constantly increasing shortage of basic foodstuffs. By applying English historian E.P. Thompson’s theory of “the mo
