A scanning tunnelling microscope (STM) mounted in a sample holder for a transmission electron microscope (TEM), a TEM-STM, have been used for in-situ electrical measurements of semiconductor nano whiskers. The device enables measurements and manipulations of nano structures while observing them in a TEM

Popular Abstract in Swedish Astma och rökarsjuka, eller mer korrekt kronisk obstruktiv lungsjukdom (KOL), är två vanliga sjukdomar som karakteriseras av att de drabbade tidvis har svårt att andas. Denna andnöd orsakas av att luftvägarna drar ihop sig. Mediciner som motverkar detta och istället vidgar luftvägarna är därför viktiga för patienter som lider av astma eller KOL. Det finns idag flera medCapsazepine and similar compounds, capsazepinoids, were shown to be general inhibitors of agonist (leukotriene D4, histamine, acetylcholine, prostaglandin D2) evoked constriction of human small airway preparations. The mechanism of action remains to be elucidated, but established bronchodilator principles, e.g. beta2-adrenoceptor agonism, as well as TRPV1 antagonism were shown to be less likely. F

Increased understanding of membrane proteins is important for characterization of biochemical processes. Improved membrane protein isolation methods is a key issue for effective functional and structural determination of the large amount of unknown membrane proteins. In this thesis, a novel approach towards selective membrane protein purification is introduced. Polymer induced micelle extraction

The work with development of new building systems is intensive. These systems are often related to lightweight constructions, and developed to be used in load-bearing structures and dwellings. One of the main drawbacks of this type of building systems is often the sound insulation. Lightweight walls and floors are often designed as frameworks of studs with plates on both sides - a double-plate str

This report focuses on critical metals in Waste from Electrical Electronic Equipment (WEEE) and their recycling possibilities. The criticality is defined in terms of demand. The EU needs access to these metals and recycling can be an important part of the supply-strategy. The report covers assessments of (1) the potential amount of critical metals in the selected product groups, and (2) the actual

A major component of aircraft noise is the jet noise created by the high velocity hot stream exhausting from a jet engine, interacting with itself and with the surrounding cold air. In the present paper the flow and acoustic fields that are generated by two coaxial jets are considered. Numerically, the problem is divided into a flow related part (Navier-Stokes system of equation) and an acoustic p

The aim of this part of the RightTimePlaceCare study (WP2) was to describe and analyse the European health, social care and welfare systems, advocacy and informal caregiver support systems for patients with dementia. The description and analyses covers the continuum of care from diagnosis, informal care, contributions from civic society, public home care and the intermediate forms of care, to the

A reduction of the negative environmental impact caused by urban traffic will to a considerable extent depend on behavioural change. Assuming that attitudes partly guide behaviour, the general aim of the thesis was to increase the understanding of the underlying attitudes of daily travel behaviour and how attitudes related to pro-environmental choice of transport can be promoted. Two questionnaire

Massive Multiple-Input Multiple-Output (MIMO) systems have been shown to improve both spectral and energy efficiency one or more orders of magnitude by efficiently exploiting the spatial domain. Low-cost RF chains can be employed to reduce the Base Station (BS) cost, however this may require additional baseband processing to handle induced distortions due to the hardware impairments. In this artic

Protein S deficiency is an autosomal dominant trait affecting around 10% of families thrombophilic families. The high affinity interaction of approximately 60% of protein S with C4b -binding protein (C4BP) has raised a complicated situation for the diagnosis of deficiency states. Because only free protein S functions as cofactor in the protein C anticoagulant, it is important to measure free prote

The Modelica language is currently gaining increased interest, both in industry and in academia. Modelica is an object-oriented, general purpose modeling language, targeted at modeling of complex physical systems. While the main usage of models developed in Modelica is simulation, several other usages emerge. Examples of such usages are dynamic optimization, model reduction, calibration, verificat

Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. The present thesis summarizes work based on four basic technologies: 1) use of Sulphate Reducing Bacteria (SRBs) for production of hydrogen sulphide which is used to

The increasing test data volume needed to test core-based System-on-Chip contributes to long test application times (TAT) and huge automatic test equipment (ATE) memory requirements. TAT and ATE memory requirement can be reduced by test architecture design, test scheduling, sharing the same tests among several cores, and test data compression. We propose, in contrast to previous work that addresse

The continuous increase in global energy consumption has led to a greater focus on the energy required for heating buildings. This thesis presents a techno-economic model for analysing low-temperature district heating networks coupled with a geothermal heat source. The model was used to analyse an existing system in Denmark with 15 connected single-family detached houses. Each of the houses has a

Dry etching is one of the most important methods of pattern transfer in nanofabrication. There are many dry etching methods, the most commonly used is reactive ion etching (RIE), that is based on a continuous supply of reactive ions and radicals generated in a radio-frequency (RF) plasma discharge. The RIE approach can be very accurate and may provide high resolution etching, below 10 nm in latera
