In the microelectronics industry, gold electrodes on silicon dioxide are produced using an adhesive layer of chromium or titanium. This method is applicable whenever a dry environment is present. However, when such an electrode is exposed to an electrolyte a galvanic cell is formed and the less noble metal will dissolve and eventually destroy the electrode. We describe here how a monolayer of merc

Liquid chromatography/tandem mass spectrometry (LC/MS/MS) was used to study the primary structure of immobilized Candida antarctica lipase B (Novozym(R)435) without detaching the enzyme from the carrier. The immobilized enzyme packed in a miniature column was subjected to proteolysis and the peptides released were injected into the mass spectrometer for analysis. The set-up was utilized to determi

Information management in construction projects is all about communicate the information, to file the document to make it available and to verify that the information is correct. Improving the information management in a project and between different projects will reduce the problems and the costs of it. To succeed with the information management the chain of information must remain unbroken from

Steriliseringslagstiftningens framväxt tog sin utgångspunkt i ”degenerationen” och oron för att industrialiseringen hade skapat en biologisk försämring av befolkningen. Det var vid denna tidpunkt som tankarna om rashygienen väcktes. Genom biologisk förädling skulle befolkningskvalitén höjas. Det fanns en förhoppning att genom positiv och negativ eugenik öka fortplantningen hos den ”goda” befolkninThe emergence of the sterilization law were based on "degeneration" and fear that the industrialization had created a biological degradation of the population. It was at this point that the ideas of the eugenics evoked. By biological processing the quality of the population should increase. There was a hope that through positive and negative eugenics increase the breeding of the "go

Skildra hur regleringen kommer till uttryck i gällande rätt samt ur ett rättshistoriskt perspektiv. Frågeställningarna för att besvara syftet: Är 15 år en lämplig straffbarhetsålder? Uppfylls förutsägbarhetsprincipen för barn under 15 år vad gäller påföljdssyThis paper deals with young offenders role in Swedish criminal law. The aim is to portray the age of criminal liability in Swedish law. Depict how the regulation is enshrined in the law as well as from a correct historical perspective. The questions to answer the purpose are: Is 15 years an appropriate age of criminal responsibility? Is the principle of predictability fulfilled for children under

Inom strålbehandling innebär den s.k. åskådareffekten ("bystander effect") ett relativt nytt tankesätt som betonar de biologiska effekterna av strålning på icke-bestrålade celler i närheten av bestrålade celler. Denna effekt har visat sig påverka inte bara de celler som angränsar till det bestrålade området utan även celler på större avstånd. I Lund pågår just nu ett projekt där man villPurpose Intensity modulation of radiation is one of several important conditions to evaluate for full understanding of how cells involved in the bystander effect influence each other when cells are exposed to radiation at low and high dose rates. The aim of this study was to develop and apply a useful and practical dosimetric method for measurement of the absorbed dose to cell cultures exposed to

This study discusses how Swedish high school teachers in religious education reason about their teaching on Islam. This study is based on interviews with six teachers about what material they use, what they mean is pivotal to understanding Islam and what their students think about Islam. The answers were analyzed using Stuart Hall´s theory of representation. The result was that those teachers that

ABSTRACT The aim of this exploratory study was to examine what motivates social workers in the drug abuse field to remain in their jobs for longer than five years. Data was collected via semi-structured face-to-face interviews with five social workers in a municipal social services administration in south-western province of Scania. The analysis empolyed qualitative approach using Herzbergs two-

Increasingly popular, distance education has been researched from many angles, but studies done from a cultural analytic perspective are rare. Most studies up to this point have focused on the pedagogical perspective. This thesis aims to investigate challenges faced by different stakeholders in distance education, including online course promoters, teachers, and students, from a cultural analytic

The aim of this study was to find out how discomycetes growing on European Marram grass, Ammophila arenaria (L.) Link, are distributed in relation to white and grey dunes. The result indicates that discomycetes are more common in the white dune area, but the difference was not statistically significant. The study also includes a genetic study of intraspecific variation in the species Albotricha ac

Sammanfattning Med ”Lindomeproblematik” menas att flera tilltalade skyller på varandra och att det inte går att avgöra vem av dem som begått brottet eller om de har gjort det tillsammans, vilket leder till att samtliga frias. Rättsväsendets förmåga att klara upp och lagföra allvarliga brott ifrågasätts därför. I denna uppsats där en rättsdogmatisk metod används är syftet att redogöra för och krit

Fotoner som penetrerar ett material har olika sannolikheter att växelverka och därmed överföra sin energi och absorberas i materialet eller få en riktningsförändring. Denna sannolikhet för fotonen att absorberas eller spridas anges ofta per längdenhet och kallas för attenuering. Sannolikheten för attenuering i ett material ökar med sjunkande fotonenergi och om materialet består av ett högre atomnuMaterial decomposition in X-ray imaging is used to separate different materials or elements in an image and to quantify their respective concentration. The material decomposition and quantification are made possible by the dependency of attenuation on the attenuating material and photon energy. The purpose of this thesis was to implement a material decomposition method, from the image acquisition
