Popular Abstract in Swedish Katalys är en nyckelteknik inom kemisk industri och spelar en förvånansvärt viktig roll i vårt moderna samhälle. Många av de produkter och kemikalier som används i vårt dagliga liv produceras faktiskt med hjälp av katalysatorer. En annan mycket viktig tillämpning är att avlägsna giftiga ämnen från fordonsavgaser. Det mest fantastiska är att en katalysator snabbar på ochThis PhD thesis reports on investigations of the atomic scale structure of model catalysts relevant for the catalytic oxidation of CO and methane over Pd, and NOx reduction over silver-alumina, important reactions in automotive catalysts. By using complementary experimental techniques such as X-ray Photoelectron Spectroscopy, High Pressure X-ray Photoelectron Spectroscopy, Surface X-ray Diffractio

A quite common view is that the scientific persona matters less in contemporary Western knowledge societies. Large research groups produce new scientific discoveries gathered around impersonal expert system. However, it is also well known that scientific cultures differ widely. In physics, the projects are quite impersonal, sometimes including thousands of persons. The prime example is the CERN or

As the contribution of dispersed or distributed energy resources (DER) to the electric power production increases, the effects on the power system grow more important. As an example a critical situation may arise if protective relays trip a large part of the dispersed generation due to undervoltage at a short-circuit event. On the other hand it is crucial that the protection system acts correctly

The principal rule of the common market is that goods and services are able to move freely across the borders of Member States. State monopolies in control of supply and demand are, therefore, only under exceptional circumstances compatible with the conditions of the common market. The compatibility of Swedish State monopolies with EC law is a controversial matter. The case-law of the ECJ lets us

Characterization of emissions from fires in a laboratory-controlled environment are presented in this report. The project is initiated by the CERN HSE Unit and is called FIRIA, Fire-Induced Radiological Integrated Assessment. The objective of FIRIA is to enhance the knowledge of aerosols emitted from fires in order to develop dispersion models of radiologically-activated material in case of fire.

INTRODUCTION: Thorough treatment planning is essential for a good clinical outcome in orthognathic treatment. The planning is often digital. Both 2-dimensional (2D) and 3-dimensional (3D) software options are available. The aim of this randomized 2-arm parallel double-blinded active-controlled clinical trial was to compare the outcomes of computer-based 2D and 3D planning techniques according to p

Background Monotherapy with anticoagulation has been considered as first-line therapy in patients with mesenteric venous thrombosis (MVT). The aim of this study was to evaluate outcome, prognostic factors, and failure rate of anticoagulation as monotherapy, and to identify when bowel resection was needed.Methods Retrospective study of consecutive patients with MVT diagnosed between 2000 and 2015.RBACKGROUND: Monotherapy with anticoagulation has been considered as first-line therapy in patients with mesenteric venous thrombosis (MVT).

Spark ablation is an established method for generating aerosol nanoparticles. By changing the electrodes, synthesis of monometallic, multimetallic and semiconducting nanoparticles has been demonstrated. Apart from using electrodes of specific composition, compositional tuning of bimetallic nanoparticles during synthesis has recently been demonstrated (Kohut, et al., 2021). In many applications, it

The preseni paper provides an overview of existing approaches for design and assessment of offshore structures and on this basis proposes a framework for the risk based assessment and monitoring of the performance of offshore wind energy converters in operation. In recognition of the fact that there are presently no established best practices for the assessment and monitoring of offshore wind ener

Sverige införde år 2009 bestämmelsen kontakt med barn i sexuella syften i brottsbalkens sjätte kapitel paragraf 10 a som kriminaliserar möte med barn i sexuellt syfte, s.k. grooming. Bestämmelsen tillkom två år efter att Sveriges dittills största nätsexhärva, målet mot ”Alexandramannen”, hade avgjorts i Hovrätten över Skåne och Blekinge. Under de åtta år som bestämmelsen har funnits har antalet laIn 2009 Sweden introduced a legislation named contact with children for sexual purposes in the sixth chapter, section 10 a in the Swedish Penal Code, criminalizing grooming. The provision followed two years after the judgement from the Court of Appeal of Skåne and Blekinge over the “Alexandra man” case, the then biggest child sex exploitation case in Sweden. During the eight years of existence of

Mänskliga kvarlevor förstås inte längre bara som föremål utan också som avlidna individer. Utställda mänskliga kvarlevor kan ha en suggestiv kraft som ger dem liv genom mötet med besökare, tillspetsat skulle man kunna säga att de befinner sig i ett slags limbo mellan liv och död. Denna studie jämför museiutställningar som innehåller mänskliga kvarlevor mellan tre europeiska länder. Syftet med upp

Robots in factories and vehicles on our roads are rapidly reaching the point of automation. Commercial markets require high standards of safety and reliability, which in turn demands strict requirements on software and hardware. This thesis presents an analysis of driver assistance for a hydro-foil speedboat using LiDAR technology. The LiDAR sensor measures 2D positions of surrounding objects and

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 purpose of conducting this study was to analyze how forced expropriations and the demolitions of informal settlements could fall under the umbrella of “climate change adaptation” measures. Using an actor-network lens and translation theory, these translations are systematically broken down between three distinct levels: global discourse, national discourse, and implementation. As the idea of a

Sverige präglas idag av en låg nyproduktion av bostäder trots att det finns en ökande och stark efterfrågan. Bostadsmarknaden domineras till stor del av ett fåtal större kommersiella byggherrar och de producerade bostäderna är tämligen homogena. Boverket konstaterar att det krävs nya sätt för att möta en ökande efterfrågan på variation från konsumenter på bostadsmarknaden. Under senare år har ettThe housing market in Sweden is characterized by a relatively low production of housing even though there is a great demand for it. The housing market is dominated by a few large commercial building companies and their products are quite homogeneous. The Swedish National Board of Housing (Boverket) has confirmed that new strategies are needed to address the increasing public demand for variation i

Purpose: Improvements in mortality rate of glioblastoma patients have been limited during the past decades, due to the tumor’s rapidly growing and infiltrative behavior and resistance to current therapy. Recent findings show that higher brain mean dose strongly correlates with inferior overall survival and that local recurrences mainly occur centrally in previously irradiated regions. This project

This study examined the acculturation strategies of immigrant adolescents in Sweden and their relation to the mental health symptoms. The participants were 101 immigrant adolescents and 52 Swedish adolescents 15 to 19 years old. ‘Immigration paradox’ was examined comparing the mental health of first and second generation of immigrants and the native Swedes. Youth Self Report was used to assess men

Recycled asphalt pavement (RAP) is a way of constructing roads with less climate impact. However, the RAP often contain moisture which is known to be disadvantageous for the final product and will at the same time increase the production cost. A manufacturing method that also aims have less impact on the environment is NCC Green Asphalt. The method allows a lower manufacturing temperature than a c

Bakgrund: I dagens föränderliga samhälle stannar inte individer inom samma organi- sation arbetslivet ut, utan det blir allt vanligare att folk utbildar sig och ändrar karriärer. En äldre generation är på väg att bli utbyt av en yngre och många gamla erfarna med mycket kunskap kommer lämna sina arbeten. På grund av detta ställs nya krav på orga- nisationer, där kunskapen som finns måste tas tillva
