This thesis is devoted to the study of different aspects of groups acting on rooted trees and their applications.First, we focus on the Hausdorff dimension of groups acting on rooted trees. We develop new tools that lead to the solution of several well-known open problems in the subject due to Abért-Virág, Bartholdi, Grigorchuk, Klopsch and Shalev among others.Secondly, we study many aspects of thThis thesis is devoted to the study of different aspects of groups acting on rooted trees and their applications.First, we focus on the Hausdorff dimension of groups acting on rooted trees.

Popular Abstract in Swedish Evolusjon og energikonservering i en katalysator i cellens kraftverk Alle levende organismer må omforme energien i mat eller sollys til en form som cellen kan bruke som energi. Energien brukes både til prosesser som bryter ned og bygger opp komponenter i cellen. Den brukes også til prosesser som muskelsammentrekninger, celledelinger og bevegelser. Uansett hva slags celComplex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. In mammals, about 50% of the mitochondrial DNA is encoding protei

Popular Abstract in Swedish Del 1. Introduktion I kapitel 1 presenteras arbetets problem, syfte och metod. Det arbete som olika frivilligorganisationer och deras medlemmar utför har de senaste åren uppmärksammats alltmer. Detta ökade intresse finner man såväl i Sverige som internationellt. Fokus i detta arbete riktas mot drivkrafterna bakom frivilligt engagemang. Det övergripande problemet är varfThis thesis focuses on the incitement to commitment and voluntary work. The overall problem is the question why you get involved in voluntary work for an organisation like Lutherhjälpen, the organisation for international development co-operation of the Church of Sweden, one of the largest NGOs of the country. The theoretical perspectives are seen from the position of the increasing pace of change

Caroline Arvaker Utan naturen kan vi inte leva I naturen finns alla våra resurser vilket gör den viktig att skydda. Detta är en gemensam värdering hos ett antal unga utomeuropéer boende i Malmö. Dock leder inte pro naturella värderingar alltid till ett miljöengagemang i handling, det finns andra faktorer som spelar in. I mitt masterarbete har jag genom intervjuer undersökt hur tio utomeuropéer ABSTRACT The purpose of this study is to examine how young adults with non-European background and with an upbringing in a city associate to nature and what may have influenced these associations. Given that a majority of people live in cities, there is a risk that many young people do not spend time in natural environments, which may affect their associations to nature and also their environment

Since the demand on ready-to-eat (RTE) and raw, minimally processed products is high and increasing in today´s market, the microbial quality is important. One of these products is RTE salads and salads mixes that are bagged and since it is supposed to be eaten raw without any step to reduce the microbial load, these types of products are considered to be risk foods and that the risk of foodborne oThe all year around available ready-to-eat salad are increasing in popularity, and parallel with this, vegetable-derived foodborne illness outbreaks as well. Can a too long shelf life for these products be part of the problem? During recent years the focus on healthy diets and lifestyles has increased. Vegetables and fruits are important to include in meals and are a part in many modern health die

To investigate the reasons why companies engage in Corporate Social Responsibility, CSR, this study conducts a survey with 47 companies and interviews with 7 company representatives in the UK. This empirical data and results are analysed in terms of theoretical ideas of CSR and economics. Board of Directors or top management, Attract employees, Reputation, Moral, and Economic reasons are, as in th

China’s economic development has made a remarkable achievement over the past three decades. However, compared with other developed economies, it still mainly relies on coal resources as its primary energy. As country’s leading coal resources producer, Shanxi is now in an awkward position. A possible explanation is this region suffering “Resource Curse”: that the abundant resources did not bring ra

Corporate social responsibility (CSR) is getting increasing interest both in theory and practice. Retailers are increasingly integrating their responsibility to environmental, social and economic their business strategies and practices. The focus in this thesis is the environmental aspects of CSR, which are referred to as green strategies and practices. Retailers are argued to have a strategic pla

This master’s thesis relates to the design of prefabricated balconies. Such balconies are often designed in different ways. A separate investigation of what is technically possible regarding, among other things, supports and balcony sizes must often be performed in every project involving balconies. Three kinds of solutions are presented. These are tie rod, cantilever and column supported balconie

For the juice package to protect and keep your juice fresh it is important that the different layers in the packaging material sticks very well together. The ability for two things to stick together is called adhesion. For the people that create juice packages, this is important to measure so that the packages don’t leak. This measurement has turned out to be very tricky, but this study has shown

The zoo is a place where you as a visitor can experience and see wild animals which they probably would not encounter elsewhere. It is a place for learning about our planets nature and biodiversity. Many species are rapidly disappearing due to human activity. There are for example more tigers in captivity than there are left in the wild. One of the zoos most important roles is the conservation of

The purpose of the thesis is to examine if it is possible to earn excess returns with a certain strategy at the Stockholm Stock Exchange. More in depth, our strategy observes whether or not there is a signalling effect of raising the dividends. We used two portfolios, one that implies that the signalling effect of raising dividends will have a direct positive effect of the stock the up-coming year

Since 1950s fossil fuels are the main source of anthropogenic emissions (Friedlingstein et al., 2019) and developing economies with their increasing demand of energy are contributing to global fossil fuel consumption increasingly. Turkey, similarly, has been experiencing an increase of energy demand and have been heavily relied on fossil fuels in consumption patterns. This study employs Fairclough
