Lake lowering in sulphide-rich areas is currently a major environmental impact for surface water. This study focuses on whether there is a relationship between a gradient of lake lowering and surface water impacts in areas of sulphide-rich sediments, in order to better understand their contribution of heavy metals and sulfuric acid. Also, is it a reasonable method to use the reduced lake area in order to quantify the gradient? The survey was conducted by collecting water samples from reference lakes and lowered lakes from south to north in coastal areas within the county of Västerbotten. Water samples were then analyzed for TOC, pH, conductivity, anions, base cations, alkalinity, acidity, sulfate, Al, Cd, Fe, Mn, Cu, Zn and Pb.

This qualitative study is done with the purpose of creating understanding for the theoretical democratic content in educational materials for Civic Education courses 1a1 and 1b during GY-11, so teachers create an intentional approach when using educational materials in their democratic education. This was motivated as important considering the reduction in obligatory Civic Education for the vocational programs. The study was conducted using a hermeneutic qualitative reading method where the educational materials, more specifically two series with one book for each course, was read with purpose of creating understanding for the democratic content according to ideal democratic models: deliberative democracy, participatory democracy and electoral democracy. A text voice analysis was also conducted using Bakhtins theory of dialogic and monologue text that contributed to the general result concerning the democratic content. The results show that the electoral democracy ideal is dominant in all educational materials, there is hence no striking difference between the democratic content in 1a1 and 1b educational materials.

To create multifunctional buffer strips along a watercourse in an economically sustainable way requires consideration of many different factors. In this plan we have selected pollutant reduction as the main purpose of the buffer strip. We have also strived to achieve minimal income loss due to reduced production, increased biological diversity, good game preservation that leads to higher income from hunting, aesthetical satisfaction and possibility to profit from available subsidies. This is done mainly to make landowners/farmers more interested in creating buffer strips along water courses.As sand is the dominant type of soil in the area, the water course is less affected by surface runoff compared to if the soil would be clay or some other finer texture. Game preservation and subsidies have therefore been the main factors when establishing the width of the strip, because these require wider buffer strips in some cases.

BackgroundResearch shows that the majority of patients feel anxiety before and during anesthesia. It has been shown in several studies that preoperative anxiety may cause adverse effects in the postoperative course. Nurse anesthetists have a key role in creating a safe environment and the opportunity to use different interventions to reduce the degree of anxiety.AimThe aim of the study was to examine which interventions may reduce anxiety in adult patients before and during both general, local and regional anesthesia.DesignSystematic literature review with a quantitative approach.ResultsSeveral studies indicate that gabapentin and pregabalin can reduce anxiety before and during anesthesia. The anxiety reducing effect appeared to be dose dependent. The naturopathic drugs Citrus aurantium blossom and Passiflora incarnata Linneaus were found to reduce anxiety before anesthesia.

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

More and more companies open up facilities and stores in countries all around the world. Entering a new country means a new culture, a new language, different norms and values and new people with a different way of thinking unlike what you are used to. In order to survive and be successful in this new country means that you have to adapt to the new culture and its components you encounter.The purpose of this thesis has been to identify possibilities and barriers in the Middle Eastern culture affecting international clothing companies. Furthermore it has been investigated how these companies must adapt their products and promotion to this culture.In order to obtain relevant data for achieving the purpose of the study interviews and observations was made at three international clothing companies in Tehran, Iran. These were Mango, United Colors of Benetton and adidas.

Syftet med arbetet är att få en förståelse för moss-sedumtakets bullerdämpande egenskaper. Jag kommer även att försöka förutsäga med hjälp av akustikteori vilken utav de två olika uppbyggnadssystemen av moss-sedumtak som ger den bästa bullerdämpande effekten.Mätningarna kommer att bestå i att registrera ljudtrycksnivån i rummet, vid varje oktavband i frekvensområdet 125-4000 Hz. Först utan moss-sedummattan och sedan med moss-sedum mattan. Storleken på differensen i ljudnivån ger en bild av i vilket frekvensområde som ljudabsorptionen är effektivast. För att ytterliggare öka förståelsen för hur moss-sedum absorberar ljud så kommer även absorptionsfaktorn att beräknas.

Huvudsyftet med denna uppsats är att undersöka effekterna av aggressionsersättningsträning (ART) program på tre kriminalvårdsanstalter och två frivårdskontor. Huvudfrågeställningen som belyses i studien är: förändras deltagarna i ART-program med avseende på empati och attityder till kriminalitet? För att besvara dessa frågor har vi utfört för- och eftertester på tre kriminalvårdsanstalter och två frivårdskontor. Instrumenten som användes i testerna är Davis Interpersonal Reactivity Index (IRI) och Mill's Measures of Criminal Attitudes and Associates (MCAA).Slutsatserna som kan dras utifrån denna studie är att den emotionella empati-komponenten "personal distress" visar en minskning som kan förklaras av interaktionen med ART.The aim of this study is to investigate the effects of Aggression Replacement Training (ART) program in some of the prisons and probation authorities of the Swedish correctional system. The specific questions we are trying to answer are: (1) does ART-program change the clients' empathic concern and (2) does ART-program help in changing participants' attitudes towards criminality? This investigation is based on a quantitative inquiry consisting of Interpersonal Reactivity Index (IRI) and Measures of Criminal Attitudes and Associates (MCAA) tests.The overall results of this study indicate that the emotional empathy-component "personal distress" shows a statistically significant reduction, which can be explained by the interaction with ART..

SammanfattningI dagens miljöfokuserade samhälle ställs det allt högre krav på den tunga fordonsindustrin varvid den gällande miljölagstiftningen skärpts i flera steg de senaste åren. Scania tillverkar tyngre fordon och motorer som alla måste följa de kommande utsläppskraven. Detta innebär att motorernas utsläpp måste reduceras varför avancerade efterbehandlingssystem har införts i ljuddämparen. En metod för att rena avgaserna från kväveoxider är SCR-teknologi (Selective Catalytic Reduction). Denna teknik bygger på att en urealösning sprutas in i avgasflödet.

The present essay concerns the Levinasian understanding of responsibility in relation to the two spheres that Levinas introduces in his second major work Otherwise than Being or Beyond Essence, namely the Saying and the Said. The essay investigates some of the different meanings that the concept responsibility takes on in regard to these two spheres, and thus also in regard to the separation between the ethical and the political that is apparent in the book. Is it possible to find a politically uttered responsibility in Levinas Otherwise than Being or Beyond Essence?The essay wants to emphasize the continuous transition between the ethical or the Saying and the political or the Said, and vice versa, with the purpose of showing how the two spheres may be conceived simultaneously. By posing the relationship between the two as a reciprocal rather than a oppositional one, the essay aims to suggest that an understanding of responsibility at once must be ethical and political.

Idag lever cirka 40-65% av Sveriges befolkning med kronisk smärta. Påverkan av kronisk smärta på en persons livsstil varierar, en del ser smärtan som en olägenhet i vardagen medan andra upplever att smärtan påverkar varje aspekt av livet. Det är inte lätt att behandla kronisk smärta då variationer på smärtan är många och diagnosen ofta är osäker. Alternativa metoder för att behandla smärta blir allt vanligare och en sådan metod är mindfulness. Syftet med studien var att beskriva den samlade kunskapen kring mindfulness verkan hos personer med kronisk smärta.

Abstract The subject of this thesis is the priority rules that apply in connection with mining activity. Already back in the 1800s, there were rules in the so-called Lego Charter concerning protection of workers, mainly servants. When the first modern trade union was founded in the 1870s, also developed a collective agreement. These agreements were the order of priority clauses had to intend to ensure employees' working lives. Exceptions had to be done by ensuring that individual employees' dependents. In 1974 the Act on employment entry and had intended to protect older workers.

The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.
