Earth science is a dynamic system science that explores the structures and processes of the earth. Knowledge about the earth is important for citizens since the science is a vital part in the sustainable development of the society. Without good basic knowledge the citizens don?t have the possibility to anticipate in the questions and decision-making that concerns e.g. anthropogenic climate change. In the Swedish school system earth science is not an independent subject until academically studies at the University?s.

The United Nations is an important organization when it comes to international peace and security. Recent events in international politics, however, have brought about a widespread concern about the abilities of the organization. Powerful states have shosen to act outside of the organization to achieve their goals. They have furthermore a disproportionate influence on the decision-making body, the Security Council.The aim of this essay is to examine wheather UN can function productively as keeper of the international peace and security in the political climate of today, and to find out to what extent the powerful states harm the organization. I use a theoretical article, concerning states relations to international organisations, to analyse the acts of powerful states in UN.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

The study's main purpose was to qualitatively investigate adult children's experiences of growing up in a family with parental abuse of alcohol and drugs, and how their childhood has influenced/influence life in adult age. In this interview study, four respondents in the age be-tween 25-60 years have participated. Social learning theory, attachment theory and risk and protective factors have been used as a theoretical frame.Overall, we can conclude that the study's respondents have, more or less, been adversely affected by the parent?s misuse of alcohol during their childhood. Despite these negative fac-tors, most respondents nevertheless received a functional living.

My purpose with this work is to find out how it relates with pre-schoolteatchers view about a quality in comparasion to control document, Lpfö-98, and with factors pre-schoolteatchers consider effects quality in pre-school describe pre-schoolteatchers view on that high quality is in pre- school.The investigation has been done by quality interviews with five pre- schoolteatchers working in pre- school. The results show that they do not make a difference between what are high quality and the factors that affect the possibility of creating high quality. Most important is qualified and engaged educationalist in the pre- school who who shows a good attitude towards the children, and where development and learning is central. The most decisive to a pre- schools quality are the personell who work there. A conditon to achieve high quality in pre- school is a head who knows the pre- school activity and its curriculum, and who takes active part in the activity, invites to discussions and offers pertinent competence development.According to the leading document Lpfö-98 you will achieve high quality by offering children rear and care.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

The Swedish agricultural sector is currently experiencing substantial structural changes, where the number of agricultural enterprises continuously decreases and the average farm size increases. In order to maintain competitiveness, it is important to be aware and adapt to changes concerning the surroundings of the company (Johnson et al., 2011). Agricultural commodity prices sharply fluctuate on the global market in recent years, affecting the profitability of farmers. High volatility market requires tools to reduce price variations and increases the need of decision-making (Bouder & Beth, 2003). Farm-based grain handling facilities increases the sale options regarding agricultural commodities; a flexible strategy to get additional compensation for the storing the grain produced on the farm (Edling, 2002; Edwards, 2013).

The purpose of this essay was to describe and analyse the tension/conflict between external demands and actual conditions, as experienced (and told in interviews) by employees at two social insurance offices in Scania, concerning their roles in the process of working life rehabilitation. The theoretical starting point is the theory of street-level bureaucrats, as defined by Lipsky. The comprehension among the employees were that working life rehabilitation services are approved less today compared to a few years ago. The discretion, i.e. the position to choose among competing alternatives; about what to do, how to do it etc., characteristic of street-level bureaucrats, according to the employees is less prominent, as the routines of handling cases and decision making are regulated.

Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

The aim of this study is to examine the interaction between a group of multilingual, twelve-year-old children, and three libraries. The children live in a suburb of a larger city. The three libraries are their school-library, the library in their suburb and the main library in the city. We have examined if and how the children use the libraries, what the libraries mean to them in their daily life and what their possibilities are when it comes to participate in and influence activities and collections at the libraries. We have pursued qualitative interviews with sixteen children in grade six and three librarians, working with multilingual children at the three libraries.

The aim with this report is to formulate a strategic method to optimize selection processes of DNA-samples from a faeces inventory to identify as many individuals in as few analyzes as possible, and by that keep down the costs of brown bear management. Brown bear management in Sweden founds today on results from faeces inventory and is substantially led by the county administration boards. Data from the years of 2004 and 2009´s inventories in Västerbotten was used to test and evaluate different methods in selection processes of which faeces that should be sampled. Comparison were made between making selection by chance, by spatial distribution and by calculating variations in logistic regressions coefficient b, in other words bear density and probability in finding same individual in several faeces. We can show making selection by chance is the most uncertain method.

Reading and analyzing literature has a long tradition of being an essential part of the teaching of English in Sweden. As the offers of entertainment have increased in popular culture with the introduction of computer games, internet and other media, interest in reading novels has decreased. Literature is still a compulsory part of English teaching and the question is how teachers of today use literature and what kind of literary instruction they use.The aim of this study is to explore and discuss the literary instruction discourse in pedagogical texts, lessons, created by and for English teachers of Swedish Upper Secondary Schools. The lessons have been collected from the site lektion.se, where teachers are able to share knowledge and lessons. The study uses an analytical method based on Norman Fairclough´s Critical Discourse Analysis in order to analyze the lessons.

The purpose of this study is to examin the depiction of culturalmeetings in history books in relatioon to the schoolguidelines, and how and why the description may have changed over time. To achieve this, a qualitative method was used to analyze the content of cultural meetings in Swedish schoolbooks after the World War II. The material used in the study was taken from eight editions of Alla tiders historia published between 1985-2011. The material was then put together and analyzed from the theoretical perspectives, which try to explain the factors that influenced the depiction of the texts.The results of this study shows, that over time, the school guidelines have incresed their focus on human value and the need for students to interact with people from other cultures. The depictions in the history books lives upp to the demands of the school guidelines, but this study shows that the main influence of the content of the book is the social context.

There are two species of voles that cause damage in Swedish fruit production: the water vole (Arvicola terrestris) and the field vole (Microtus agrestis). Both species make the most damage during the winter season. The water vole makes subterranean burrows and cause serious damage by gnawing on the tree roots. The field vole seldom makes burrows and gnaws the bark at the base of the tree trunk. In recent years there have been several reports about increasing vole damage.
