Carbonyl exchange between [MX3(13CO)]–(MX = PdCl, PtCl or PtBr) and 12CO has been studied by IR and 13C NMR spectroscopies as a function of temperature. The exchange is first-order in both CO and complex concentration, and the activation entropies are negative, suggesting an associative reaction mechanism. There is a small solvent effect, but no chloride dependence.

The Counts memorials: A short presentation and interpretation of a number of memorials erected by the count Per Brahe junior between 1653 and 1680 on Visingsö and in Skärstad in Småland, at Dimbo in Västergötland and Östra Ryd in Uppland.

The subject of this paper is ship carvings in Skåne, Blekinge, Halland, Småland, Västergötlandand Östergötlandand to investigate if there is any difference between the ship carvings at the shores compared to the ship carvings in the inland. But there is a lack of these carvings in what would be called inland so a third category is used. This category is ship carvings at larger lakes and is central

Even the simplest cameras today house a plethora of impressive mechatronic systems. One of the key systems that determines the camera performance is the image stabilization, as involuntary hand movements during exposure can produce unsharp images. One way to compensate is by an internal image sensor stabilization system. This thesis describes the design and implementation of a 2 degrees of freedo

For several years, Finland has dominated the PISA surveys with their good results and conclusions have been drawn about the reasons behind Finland’s success. The Swedish National Agency for Education (Skolverket) stated in a report from 2005 that the Finnish education politics tends to be tinged with a higher amount of consensus compared to Sweden and that this may be a reason for the Finnish high

We apply the GARCH-copula method to estimate Value at Risk (VaR) for European and Stockholm stock indices. First, marginal distributions are estimated by the ARMA-GARCH model with normal, Student-t, and skewed t distributions. Then we investigate the tails of innovations of ARMA-GARCH models using the Peaks over thresholds method and find that the distributions of stock returns are asymmetric

Abstract The purpose of this study is to create an understanding of how radical right-wing parties attract female votes, with a focus on the Swedish Democrats (SD) in Sweden. This party typically takes on a more critical approach against equality and their voters are mostly young, white men, which makes it interesting to study how they attract womens votes. By studying the Swedish Democratic women

This study aims to investigate how the former British colonies, Nigeria and Sierra Leone have developed after gaining independence and which factors have played the most significant role in their economic growth. The two countries have experienced different economic growth which justifies the purpose of the study. This will be conducted using a 'Most Similar Design System'. The goal of thi

Reaching intended effects of the covid-19 pandemic vaccination is dependent on both coverage rates and time. Without vaccine mandates in Sweden, communication strategists have become essential to succeed. Vaccine hesitancy is complex with reasons differing on an individual level. This makes mass communication suboptimal, but also mainly what is used due to practical reasons. Consequently, understa

This thesis reviews existing research on how cybersecurity affects flight safety and to what extent these threats are addressed in regulatory requirements. This mixed method thesis employs anchoring in safety science, systematic literature review, legal requirements analysis, interviews, and a survey. Research shows risks related to unencrypted VHF/HF radio, CPDLC, ACARS, Mode-S, ADS-B, TCAS and G
