Inom industrin används diverse katalysatorer för att påskynda reaktioner. En av dessa reaktioner är etenoxidationen. Även om etenoxidationen är en välanvänd reaktion så är de bakomliggande mekanismerna okända. För att fullt ut förstå reaktionen krävs förståelse för reaktionsvägarna samt reaktionsfragmenten. Olika ytor påverkar reaktioner på olika sätt och det är därför viktigt att hitta en katalysSilver has been proved as a heterogeneous catalyst for styrene epoxidation via detection of reaction fragments. After dosing styrene to the surface, reaction fragments were identified by comparing with literature values. The fragments were the oxametallacycle of styrene, carboxylic groups, benzene, and carbon residuals. The used surface were composed of a Pt(111) substrate, a one monolayer thick F

Streptomyces species are known for their bacteria-untypical growth and sporulation. Growth by tip extension building up a mycelium consisting of long branching hyphae is a highly polar and regulated process. An essential protein invalved in hyphal growth and branching regulation is DiviVA. In S. coelicolor branching and growth is regulated by phosphorylation of DiviVA by the serine/tlu•eonine lc

Forskningen visar att kvinnor är mer utsatta av stress än män mycket på grund av den dubbla arbetsbördan av arbete, hem och familj. De vanligaste orsakerna till psykosocial stress bland kvinnor är stress vid separationer, stress i äktenskapet och stress i arbetet. Syftet med detta projektarbete var att ta reda på om kvinnorna som jobbar med montering av armaturer på ackord dagtid känner lika mycke

This report is a continuation of the report, Crystal nucleation of poorly soluble drugs, I Method development and initial results. [1] The aim of the studies was to experimentally investigate the crystallization process. The focus has been on crystal growth, crystal dissolution and primary nucleation. For three model substances, Bicalutamide, Linaprazan and Felodipine, experiments have been carrie

Syftet med denna undersökning var att se om vidtagna åtgärder i den fysiska arbetsmiljön på ett gjuteri som använder bland annat bly i sina gjutlegeringar. Och om detta haft effekt på upptaget av bly i blod hos den anställde. Studien genomfördes med muntlig information till den anställde om arbete med bly och företaget gjorde förändringar av utsugshantering, rökstopp inne på fabriken samt ändrade

Planetsystem bildas tillsammans med en stjärna då ett gas- och stoftmoln kollapsar av sin egen gravitation. Ur denna kollaps bildas en protostjärna, omgiven av en så kallad protoplanetär skiva bildad av det överblivna materialet. Då stoftkorn i skivan kolliderar bildas större och större partiklar. När kilometerstora is- och stenblock, eller planetesimaler, har bildats, kan dessa kollidera med varaIn models of dust growth in protoplanetary discs focus is typically on coagulation, a mechanism which unfortunately seems incapable of forming particles larger than centimeters. The main reasons for this are that collisions between larger particles lead to bouncing or fragmentation rather than sticking, and that particles approaching meter-sizes drift radially inwards in the disc due to interactio

This thesis/project work was initiated to establish a fast, < 10ms communication speed between ‘National’s Instrument Compact RIO’ which is a reconfigurable embedded control and acquisition system and ‘Vacon’s Frequency Converter’ to have command over an electric machine in a dynamic fashion. Task also included setting up a test rig, where parallel hybrid truck platform can be tested. Communicatio

Popular science This study is about the water balance of two forest stands. The water balance here means the inflow of the water by rain and outflow by evaporation and groundwater flow. The main question of this research is how increased air temperature and change in the precipitation will affect the water balance of these forests. This has been done through a modeling program which will be descriRecent studies show that future climate change will have a major influence on the water balance of forests in which the projected increase in air temperature and variation in the precipitation around the world are expected to be among the most important drivers affecting the forest’s hydrological cycle. The objective of this study is to compare the water balance of two forests stands in two diff

Uppsatsen behandlar skyldigheter under det internationella regelverket för de mänskliga rättigheterna i området våld i hemmet, med inriktning på vilken utsträckning stater anses ha en skyldighet att införa obligatoriska åtalsregler (närmast jämställt med allmänt åtal) för våld i hemmet. Med våld i hemmet avses mäns våld mot kvinnor i nära relationer och uppsatsen genomsyras av ett strukturellt perThis thesis examines international human rights law obligations regarding domestic violence, with a focus on to what extent there is a state obligation to implement mandatory prosecution policies in domestic violence cases. Domestic violence is understood as men’s violence against women in an intimate relationship and a structural perspective of domestic violence, in which the violence is seen as

This thesis takes a new look at the determinants of the growth in labour compensation since the 1970s. A number of studies have shown that, over the past few decades, income has shifted dramatically from labour to capital, not the least in Europe. Kliman (2011), however, who looks at the corporate sector in the US, maintains that the labour share has remained constant relative to property income a

I svensk rätt stadgas en plikt, eller tvång om man så vill, att ingå avtal på försäkringsrättens område. Ett försäkringsbolag får enligt 11 kap. 1 § försäkringsavtalslagen inte neka någon att teckna en personförsäkring som bolaget normalt tillhandahåller allmänheten när det har fått de uppgifter som behövs, såvida det inte finns särskilda skäl att neka försäkring med hänsyn till risken för framtidSwedish law stipulates a duty, or compulsion, to enter into a contract in the field of insurance law. An insurance company may not deny anyone to take out personal insurance which the company normally provides the public when it has received the required data, unless there are particular reasons to deny insurance with reference to the risk of future claims, the nature of the intended insurance or

The thesis aims to explore what influences the Danish consumers when choosing food distribution channels in 2020 and further to test if current theories of consumers’ channel choice can be applied in the year of 2020. The thesis takes on a qualitative approach with mathematical principles and employs the Delphi Method as the primary method to collect data. To conduct the empirical analysis a desk

There is an economic interest in the development of reliable climate models that can give us a good estimation of the present and future climate. Farmers, electricity- and insurance- companies are some of the clients that need long term (monthly) weather information from the Swedish Meteorological and Hydrological Institute (SMHI). This work focuses on the evaluation of the Rossby Centre Regional

Migration kan medföra problem för flera generationer. Det kan också vara något p

The law that banned doping substances in Sweden was founded in 1991 and was strengthened in 1999 and 2011. The use of anabolic androgen steroids (AAS) however, is still increasing. Research about AAS is limited and the approximation of the number of AAS users is uncertain. On the gyms there are warnings about punishments risked if one is caught using AAS. But those warnings are without any informa

The thesis discusses the European Commission's application of the full-function criteria to joint ventures based on the method of their establishment. While the Commission's practice is clear when a new joint venture is established, it has been very inconsistent regarding operations when joint control is acquired over pre-existing undertakings, thus transforming them into joint ventures. T

Klassificerning av biologiska och icke-biologiska partiklar är av avgörande betydelse inom många forskningsområden och inom industrin, inbegripet biologi, medicin och så kalladtissue engineering. Gemensamma parametrar i inmärknings-fri separationutgörs vanligen av storleken, formen och de mekaniska egenskaperna hos partiklarna. Anordningar baserade på deterministisk sidoförskjutning (DLD) har upp

This essay argues that acedia is a helpful concept in illuminating the fiction of the American author David Foster Wallace, particularly his unfinished novel The Pale King. Following a brief biographical sketch of Wallace, the essay explores the development of the term acedia—which means something along the lines of apathy, sloth, and listlessness—and the two types of acedia: personal acedia and t
