Katalysatorer är viktiga för effektivisering av både industri och spetsforskning. Att se enstaka atomer är inte möjligt i vanliga ljusmikroskop, så högupplösande elektronmikroskop har använts för att bestämma storlek hos katalytiska guldnanopartiklar mellan 5 och 20nm.In this project catalysts have been analyzed, in the sense of size and composition, using a Transmission Electron Microscope (TEM). This important class of substances are used to facilitate chemical reactions, in everything from specific molecular research to conversion car emissions which explains the importance of research. Nanoparticles of gold (Au) have been shown to have good catalytic perfor

Uppsatsen behandlar om normer kring kön påverkar tillämpningen av rekvisitet socialt nedbrytande beteende i Lag (1990:52) med särskilda bestämmelser om vård av unga (LVU). Tanken är att med hjälp av teori och kvalitativa studier i form av intervjuer belysa om normer om kön påverkar flickors och pojkars bedömningar och då också indirekt deras rättssäkerhet i de här fallen. Och om det kan vara så atThis thesis examines if there are any differences depending on gender in interpretation of the procedural requirement ”socially destructive behaviour” in the LVU. Furthermore, if ethics and expectations about gender influence transpiracy and legal certainty in these cases. The purpose is to find out if there are moral codes and expectations about how a girl or a boy should behave, which are not a

This meta-analysis synthesized 60 effect sizes from 41 papers (overall N = 17.226), about the relation between self-efficacy beliefs and creativity. Taken as a whole, the relation between those two constructs, assuming a random-effects model, is with r = .39 of medium size, as was proposed. Further subgroup analyses revealed a pattern of self-rated creativity measures (r = .53) those which use ite

Syftet med denna uppsats är att studera mediala fenomen i Gertrud Hellbrands romaner vinthunden (2004) och Scenario X (2008). Analysen är i huvudsak baserad på perspektiv hämtade från det intermediala och queerteoretiska forskningsfältet. För att studera mediala inslag, samband och samspel använder jag mig av en medialitetsmodell som fokuserar på intra-, inter- och transmediala fenomen, mellan med

Drones used for illegal purposes is a growing problem and a way to detect these is needed. This thesis has evaluated the possibility of using sound analysis as the detection mechanism. A solution using linear predictive coding, the slope of the frequency spectrum and the zero crossing rate was evaluated. The results showed that a solution using linear predictive coding and the slope of the frequen

This paper examines the impact of years of schooling on female employment decisions and on the intensity of employment by using the variation across countries and over birth cohorts in compulsory schooling reforms. The sample includes women aged 25 to 64 from five eurozone countries and the data covers the year of 2010. The findings suggest that years of schooling do not have a significant effect

Thermoelectric elements have long been anticipated to challenge conventional solutions for converting heat to electricity. However, the revolution has been stalled due to the inability to reach efficiencies comparable to their conventional counterparts, while retaining a high output power. In this work we will model a thermoelectric element based on nanowires embedded with a quantum dot superlattice

The purpose of this thesis Conducted Improvisation is to study how a musical sign language can effect creativity, musical interaction and sense of freedom in ensemble playing by analyzing Extemporize, a sign system I have developed, with the further goal to explore the pedagogical potential in this practice. The research questions that drive this study are: In what ways does the sign system effect

I have spent time on one of the largest Internet forums t

This study aimed to investigate parents’ attitudes towards pedophilia, i.e. their knowledge about pedophilia, stigma of pedophiles and how the society should react to child sexual abuse. Twenty participants were conducted into the survey to answer questions. The study revealed that parents’ attitudes against pedophiles and child molesters were negative and that pedophiles elicited fear in partici

Informationssäkerhet är idag en stor angelägenhet för organisationer runt om i världen. I takt med att den tekniska utvecklingen går framåt skapas allt fler sätt där känslig information blir utsatt för externa hot. Det finns idag många studier kring informationssäkerhet där granskning sker gällande den mänskliga faktorn, som är en viktig komponent inom detta område. Den mänskliga faktorn innebär ä

In order for our energy consumption to be sustainable, we need to rely more and more on renewable energy resources, such as solar power and wind power. In Sweden, 69% of the land area is covered in forest. To open up the possibility of exploiting these forested areas for wind power production, it is desired to gain a better knowledge of the flow situation above forests. An analytical and a numeric

The aim of this study was to understand how care providers/ staff in nursing facilities for older people express the way they conduct their work. The purpose was based upon earlier research indicating a gap between policy and everyday practise. The questions were formulated on the basis of earlier research pointing to an inability for nursing homes to be flexible when faced with the needs and righ

Riskbedömningar i Europa har vid flera gånger pekats ut som att undermåliga. En aspekt som ofta förbises är den av pH-nivåer hos det omgivande mediet. Eftersom 80% av alla läkemedel är joniserbara, vilket påverkar biotillgänglighet och därför toxiciteten för ämnet, kommer ett förbiseende av denna aspekt skapa en stor osäkerhet i risk. Denna studie visar att riskerna med joniserbara föreningar i ÖsRisk assessments in Europe have at multiple times been pointed out as being substandard. One aspect that is often overlooked is that of the pH levels of the surrounding medium. Since 80% of all pharmaceuticals are ionizable, which affect the bioavailability and therefore toxicity of the compound, overlooking this aspect will create a great uncertainty in the risk. This study shows that the hazards

Scholars have argued that successful policymaking should take into account the systemic aspect of a Regional Innovation System and involve a variety of actors in policy processes. Leadership is an important element for enabling collaboration and coordination among these actors, for example in the emergence of policy networks. The aim of this study is to provide a dynamic view of leadership in poli

Monofunctional towns of Russia represent the extreme case of specialized settlements where the socio-economic development mostly or fully depends on the performance of one or a few town-forming enterprises. This phenomenon obtained attention after the Soviet Union collapse, which has resulted in worsening of the socio-economic situation in monotowns. However, since the 2000s the differentiation in

Article 16 of the VAT Directive, which regulates the self-supply of goods, is a good example of how it is complicated to achieve fraud resistance and full compliance with the principle of fiscal neutrality in the current system of VAT. This provision concerns taxation on business goods used for private purposes, which has shown to be a complex area of VAT. Although the application of this rule has
