In this study, the transmission and reflection of two conductive fabrics are investigated in the frequency range from 2 to 18 GHz. One of the fabrics is a non-woven polypyrrole and the other consists of a polyethylene warp with steel threads in the weft. Reflection and transmission measurements are performed in order to characterize the electromagnetic properties of the materials. Reflection measu
Pressurized Liquid Extraction was utilized for the extraction of seven selected polychlorinated biphenyls (28, 52, 101, 118, 153, and 180) from a naturally contaminated fishmeal and two feed samples fortified with a naturally contaminated fish oil sample. In order to assure sufficient extraction efficiencies, the extraction solvent, the extraction temperature, and the flush volume were optimised b
drilling at Rostanga in 1997, referred to as Rostanga 1, penetrated a significant portion of the Upper Ordovician-Lower Silurian succession in this classical Lower Palaeozoic outcrop area in W-central Scania. In descending order the Upper Ordovician of the core embraces the following units (stratigraphic thickness in parenthesis): Lindegard Mudstone (27.8 m), Fjacka Shale (13.6 m), Mossen Formatio
Attosecond pulses allow the study of electrons on their natural timescale. They are created from the interaction of atoms with ultrashort, intense laser pulses whose electric field approaches the strength of inner-atomic electric fields. This thesis presents experiments around the generation, characterization and application of attosecond pulses. First, we study the influence of the atomic genera
Neural interfaces hold great promise to become invaluable clinical and diagnostic tools in the near future. However, the biocompatibility and the long-term stability of the implanted interfaces are far from optimized. There are several factors that need to be addressed and standardized when improving the long-term success of an implanted electrode. We have chosen to focus on three key factors when
A purpose of phenomenological studies, using the Meaning Constitution Analysis method, is to reach behind the natural attitude, the totality of the presumptions made about the entities constituting a situation experienced by an individual, and get an understanding of why the Life-world, the world in which the individual is living his daily life, is experienced in a specific way. The experiences of
Popular Abstract in Swedish Forskningen som presenteras i denna avhandling fokuserar på tillverkning av små strukturella enheter (komponenter) samt tillämpning av ny teknologi för att adressera viktiga medicinska forskningsfrågeställningar. Framtagande av teknologi som använder sig av komponenter som är tusentals gånger mindre än bredden på ett hår är svårt men möjligt. Denna avhandling fokuserar This thesis focuses on the study of thin-film sensor technologies, novel microfabrication technologies, and thin-film technology in general. The work discusses electrochemical sensors and mechanical sensor technologies as well as fabrication strategies for them. Also included are mechano-chemical studies of the vancomycin DAla (Bacteria membrane analogue motif ) binding reaction in different chemica
This article introduces a continuous, gas-phase method for depositing thin metallic coatings onto (nano)particles using a type of physical vapor deposition (PVD) at ambient pressure and temperature. An aerosol of core particles is mixed with a metal vapor cloud formed by spark ablation by passing the aerosol through the spark zone using a hollow electrode configuration. The mixing process rapidly
Försäkringskassan är en central del av den svenska välfärdsstaten och för¬medlar mycket stora penningsummor. De förändringar som myndigheten har genomfört under senare tid i form av ny organisation och ändrade besl¬utsregler har varit omdiskuterade. Kritiker har pekat på bristande effektivi¬tet, försenade utbetalningar och hjärtlös regeltillämpning. Ett antal vägval har gjorts för att söka hitta l
Cold sensitivity is a common and persistent complaint after various hand injuries and diseases. The general aim of the thesis was to investigate the consequences of cold sensitivity for daily life in patients with traumatic hand injuries and hand-arm vibration syndrome (HAVS). To obtain a richer and more comprehensive picture reflecting the aim, studies with a quantitative and a qualitative design
The recent finding that the formation of staphylococcal enterotoxins in food is very different from that in cultures of pure Staphylococcus aureus sheds new light on, and brings into question, traditional microbial risk assessment methods based on planktonic liquid cultures. In fact, most bacteria in food appear to be associated with surfaces or tissues in various ways, and interaction with other
We performed simulations of future biophysical vegetation-climate feedbacks with a regional Earth System Model, RCA-GUESS, interactively coupling a regional climate model and a process-based model of vegetation dynamics and biogeochemistry. Simulated variations in leaf area index and in the relative coverage of evergreen forest, deciduous forest, and open land vegetation in response to simulated c
We extend the commonly used synthesis strategies for responsive microgels to the design of novel multiresponsive and multifunctional nanoparticles that combine inorganic magnetic, metallic/catalytic and thermoresponsive organic moieties. Magnetic responsiveness is implemented through the integration of silica-coated maghemite nanoparticles into fluorescently labeled crosslinked poly(N-isopropylmet
Popular Abstract in Swedish Avhandlingen beskriver och analyserar hur människor som arbetar i ett företag som blir uppköpt upplever uppköpsprocessen. Författaren lyfter fram de många olika tolkningar och upplevelser som finns av uppköpet istället för att ge en homogen återgivning. Författaren hävdar att för att kunna förstå vad som händer i ett företag under en uppköpsprocess så måste man beakta dWhile the human side of mergers and acquisitions is increasingly focused in both research and practice, it still suffers from several forms of oversimplifications. This study addresses the problem of how various employees interpret objectives, corporate identity and other meanings associated with the post-acquisition process, and what roles these multiple interpretations play during this critical
We have investigated spin accumulation in Ni/Au/Ni single-electron transistors assembled by atomic force microscopy. The fabrication technique is unique in that unconventional hybrid devices can be realized with unprecedented control, including real-time tunable tunnel resistances. A grid of Au disks, 30 nm in diameter and 30 nm thick, is prepared on a SiO2 surface by conventional e-beam writing.
