Fabrication and characterisation of buried metal contacts in compound semiconductors are demonstrated. The contacts have been investigated due to their usage both as gates in transistors and as active or passive elements in novel devices. A detailed description of the processing conditions for fabrication of nm-sized W-structures in a lift-off process is given. These structures have been embedded

Delamination and spallation of thermal barrier coating (TBC) systems, used in hot parts of gas turbines, have been studied with respect to thermal fatigue. TBCs with and without pre-existing cracks were investigated. Thermal shock tests were performed until coating spallation. The experimental results revealed that the cracks primarily responsible for spallation grew horizontally, close to the int
A number of approaches for fungicide determination are presented. A surface sampling technique is utilised for the determination of fungicide foliar residues on greenhouse surfaces, mainly leaves. The procedure is based on solvation of the fungicides on the leaf surface with ethanol and HPLC analysis. It was applied to studies of the environment in greenhouses including investigations of decline r
Vi står inför en informationshantering av en karaktär som människan aldrig tidigare stått inför. Teknologin är en integrerad del i samhällets alla nivåer, såväl som i individens vardagssysslor. Människan har lagt sig till med en livsstil där informationsteknologin utgör en naturlig del i hennes handlande och, inte minst, tänkande. Det föreligger alltså ett slags mental förändring som är knuten til
Outliers pose a problem in all real structure from motion systems. Due to the use of automatic matching methods one has to expect that a (sometimes very large) portion of the detected correspondences can be incorrect. In this paper we propose a method that estimates the relative translation between two cameras and simultaneously maximizes the number of inlier correspondences. Traditionally, outlie
Popular Abstract in Swedish Av de 4278 personer äldre än 75 år som ingick i studien vårdade 18 % (n=783) någon annan person pga. dennes nedsatta hälsa. Urvalet var stratifierat. Svarsfrekvensen var i de olika åldersgrupperna 75-79; 60%, 80-84; 56%, 85-89; 48% and 90+ 42%. Av vårdarna var 58% (n=326) män. 81% av männen var gifta, vilket var fallet för 53% av kvinnorna (p<.001). 85% av männen och 59Older people take a great share of caregiving responsibility already and thus understanding of their strain, coping and satis-faction is required. The aim was to investigate dimensions of caregiving activities among elderly (75+) caregivers and to study the dimensions in relation to health-related quality of life (Paper I). It was also to investigate quality of life in relation to loneliness, care
Tyrosinase and tyrosinase-related protein-1 are enzymes involved in melanin synthesis and specific to the melanocyte and the melanoma cell. In the studies upon which this thesis is based, these enzymes were investigated in normal melanocytes, cultured human melanoma cells and transfected mouse fibroblasts. Tyrosinase was isolated from cultured melanoma cells and from bovine eye preparations, and t
Drawing on a combination of empirical industry observations and management literature, this document at- tempts to shed some light on the usage of the term ‘convergence’ that can be identified within the security sector. The aim is to provide both a typology of definitions and a discussion of some of the strategic implica- tions of different types of convergence. A basic distinction is made betwee
Environmental awareness and behaviour among the population in Malmö.
Following the 2008–2009 global financial crisis, ‘green energy economy’ packages have been implemented to stimulate sustainable economic growth in several Organisation for Economic Co-operation and Development (OECD) countries. Clearly focused on the energy sector, these packages typically include energy-efficiency policy measures and aim to encourage the transition towards a low-carbon economy. W
