Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. Large surveys are up and coming, and several surveys are already working, and with these, the aim is high quality abundance measurements of several ele

The shift to agriculture as the main form of subsistence practice allowed past peoples the freedom and potential to exploit their natural and man-made environment for personal and societal gain. Decades of archaeological excavations conducted on the Swedish island of Öland have amassed a wealth of information regarding the subsistence and settlement patterns of Iron Age societies. This thesis aims

Environmentally safe disposal of urban waste is a global concern that recently gained a new dimension through the lens of Environmental Justice, with a growing literature showing correlation between the placement of waste facilities and disadvantaged groups in society. This thesis seeks to verify whether landfills in the city of São Paulo are located in regions where socially and economically vuln

Statligt stöd är ett område för konkurrenslagstiftning. Statsstödsåtgärder används för att avhjälpa marknadsmisslyckanden och hjälpa företag när de står inför svårigheter. Statsstödskontroll syftar till att skapa lika villkor för stödda och icke-stödda företag. Under finanskrisen 2007–2009 har flera banker stött på svårigheter, och medlemsstaterna har tvingats hjälpa dem på olika sätt. Europeiska State aid is an area of competition law. State aid measures are used to remedy market failures and to help undertakings when they are facing difficulties. State aid control aims at ensuring a level playing field between aided and non-aided firms. During the 2007-2009 financial crisis, several banks have encountered difficulties, and Member States have been forced to help them out through diverse m

The underlying reason for this essay was the current chal-lenges of acquiring and keeping competent personnel within the Swedish health care. The purpose statement was to ana-lyze how managers at a Swedish hospital work with talent management, with the focus being on the terms participat-ion, motivation and communication. This was carried out through a qualitative interview study, based on social

Two relatively new concepts in planetary science are planetary migration; wherein the planets migrate through the protoplanetary disk as they form, and pebble accretion; wherein the planetesimals which become terrestrial planets and giant planet cores grow through the accretion of small pebbles. Planetary migration has become a generally accepted concept but there is still much to be learned even

The transition from a reliance on fossil resources to the use of renewables for the production of energy, fuels and chemicals is essential for ensuring the sustainability of continued human development. Plant-based biomass is a renewable resource which can be transformed into all of these products. However, biomass is a heterogeneous material composed of several fractions with different chemical p

Bed material agglomeration was studied experimentally in a fluidized-bed biomass combustor, Four biomass fuels, four bed materials, three bed additives, and three NOx additives were tested in a temperature range of 670-870 degreesC and at two pressure levels of 1.0 and 1.5 MPa. Two types of agglomeration were observed, a homogeneous and a heterogeneous type. The first occurred at low temperature a

The Lorentzian lifetime widths of the 4d and 4f levels in the sixth-period elements W74 to Bi83 have been measured using photoelectron spectroscopy. A compilation of 4f-level widths from the literature is also made. The general trend of the 4f-level widths is well reproduced by McGuires calculations, although the absolute widths seem to be underestimated. The 4d5/2-level width shows a remarkable c

Popular Abstract in Swedish Is är något som de flesta människor i Sverige kommer i kontakt med dagligen,om det är för att kyla en dryck eller ta sig en glass, är det något som de flesta är bekanta med. Om en vattenlösning eller en vattensuspension kyls under fryspunkten för vatten ( 0 °C) så börjar iskristaller att bildas. Speciellt med denna process är att iskristallerna som bildas består endast Macroporous hydrogels are regarded as interesting materials both within biotechnology and biomedicine due to their properties. These materials can be prepared from a wide range of synthetic or naturally occurring compounds using a number of different techniques for their production. For this thesis, cryostructuring was used to prepare macroporous hydrogels, often named cryogels. The work utilized

In contexts of transnational migration, language skills provide the key to employability and successful integration into host country societies. To enhance the learning process, and facilitate transitions into the workforce, integrated programs of L2 learning have been developed in several Nordic countries. In these undertakings, language learning, vocational education, and workplace practice are

Anthropogenically land cover modifications and human presence in natural environments are not without consequences to ecological processes. From a conservation perspective, these consequences are worrisome specially when considering the human domination of terrestrial ecosystems worldwide. The recent loss of wilderness areas has been described as catastrophic despite pro-active conservation scheme

Aluminum matrix fly ash (AMFA) cenosphere composites were fabricated using the stir casting technique. The used type of fly ash cenosphere, which accounted for over 60% in all fly ash particles, was in narrow and small size (2-30 μm). During synthesis, effects of several key technological parameters on microstructure and properties were investigated using orthogonal experimental design. The optima

Recycling of brake pads is a tough but promising work considering the current end of lifecycle. This study assesses the environmental performance of brake pads made up of recycled friction materials in terms of energy use, CO2 footprint and airborne particle number. Energy use and CO2 footprint are calculated with the data from CES Edupack and airborne emission particle number is measured on a pin
