Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasin
Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasinHugo de Campos PereiraSyftet med detta arbete har varit att kartlägga vilka mekanismer som styr lösligheten av sällsynta jordartsmetaller (eng. rare earth elements, REE) i sulfidhaltig anrikningssand vid den föredetta gruvan Källfallsfältet i Västmanland. För syftet har markvatten- och grundvattenprovtagning utförts, tillsammans med laktester och geokemisk modellering med Visual MINTEQ ver. 3.0.Resultaten visade att sulfidvittring är den främsta processen som styr pH i anrikningssanden, och därmed också indirekt REEs löslighet. Däremot är sulfidvittring ingen källa till REE i sig då ämnena inte föreligger sulfidbundna, något som oxiderat tillgänglighetstest NT ENVIR 006 visade.
Fastighetsmäklarens klädsel : Hur påverkar den kunden?
Real estate managers work in a hard branch with big competition and skeptical customers. For most people, buying a property is the biggest private purchase of their lives. This puts a big pressure on the real estate agent to make the process run smooth. But how does the customer know which real estate manager to choose? We have researched what effect the real estate managers clothing has on the customers? first impression and how clothing affects customers? choice of real estate agents.To answer our questions we´ve done 13 projective interviews with ten customers and three real estate agents, where we showed four pictures with the same person dressed in different styles.
Miljökonsekvensbeskrivning med stöd av geografiska informationssytem (GIS) : bullerstudie kring Malmö-Sturup flygplats
Den övergripande målsättningen med denna uppsats är att visa hur GIS kan fungera som stöd i en MKB. För att exemplifiera detta genomförs i denna uppsats en specificerad studie kring flygbullerpåverkade områden vid Malmö-Sturup flygplats. Flyg-bullerkartor erhölls från Luftfartsverket (LFV). Analyser gjordes för olika startriktningar om flygbullrets interferens med bland annat människor, naturvård, kulturmiljö, friluftsliv, fastigheter (egendomar) samt med några tätorters expansionspotential. Jämförelser genomfördes mellan flygplanstyperna McDonell Douglas MD80 och McDonell Douglas DC9.
Att leva grönt är skönt ? men tänker vi likadant? : En retorisk analys av Coop som grönt företag
The purpose of this study is to examine a brand?s green marketing and its consumers? perception of it in order to compare these views. The idea is to find a potential gap and what effect it may have on the brand. A case study has therefore been made with the grocery market brand Coop with focus on organic food. The material used consists of texts from Coop?s website to represent their brand.
Miljöstrategisk jämförelse mellan två reningsmetoder för enskilda avlopp
Den här studien syftar till att göra en miljöstrategisk jämförelse av två olika tekniker för rening av enskilda avlopp. Detta innebär en jämförelse av såväl juridiska som ekonomiska aspekter utöver den grundläggande reningseffektiviteten. Målsättningen är att visa att en rotzon är ett väl så bra alternativ som en markbädd vid rening av enskilda avlopp. Detta visade sig också stämma. Beträffande reningseffektivitet verkar teknikerna vara likvärdiga.
Hatbrott & nationalism i Sverige, finns det ett samband?
AbstractMedia presents hate crimes and nationalism as phenomenon that has increased both internationally and nationally in recent years. Further media largely pair these phenomenon together. The groups mostly exposed to hate and nationalism are people of different ethnic origin and LGBTQ (lesbian, gay, bi, trans and queer) people. In Sweden's general election in 2010 a RHP-party, Sweden Democrats, made it in to Parliament. The purpose of this study was to examine how hate crimes and nationalism, in the form of the Sweden Democrats, has increased in Sweden and if there was any link between them.
Reglering av högfrekvenshandeln
SammanfattningHögfrekvenshandeln är ett mycket uppmärksammat och aktuellt fenomen. Många är skeptiska till högfrekvenshandeln vilket delvis kan bero på hur media har framställt det. Allmänheten känner en viss oro till högfrekvenshandelns och dess samband till marknadsmissbruk. Handeln sker på en fragmenterad marknad som gör det svårt med en hundraprocentig insyn på de svenska börserna. Därför vill författarna undersöka om regleringar bör introduceras för att skapa en säker och kontrollerad marknad i syfte av att undvika framtida krascher.Studiens primärdata har samlats in genom tre semi-strukturerade intervjuer med respondenter som är bekanta med högfrekvenshandel.

Traditionell ekologisk kunskap i en framtid med lokala, självförsörjande och urbana samhällen
Several scenarios point toward a future where we are far more people on Earth than today, where most of those people will live in cities and where oil no longer dominates in the transport systems and in agriculture as an energy source and where less energy will be available to us. The report investigates what areas in traditional ecological knowledge that can contribute to the transition that follows a future with less energy and establishes three areas with the potential of becoming important: areaspecific biological knowledge in societies that are more dependent upon its surrounding environment and its natural prerequisitesthe local management of these biological resources, which often means a fair sharing and sustainable handling of the resources and which has been observed in Nobel price awarded Elinor Ostrom?s researchthe world views that lie behind how the environment is considered and managed, world views that can inspire and point toward how we in the future should formulate world views that do not give the destructive modern management of the environment It is also noted that the magnitude of the city living in the future is a historical news and that very little research has been done in how traditional knowledge can be transferred into this kind of living..
"Skyll inte på friheten" : en analys av den liberala miljödiskursen i Sverige
The paper is a discourse analysis of the liberal environmental discourse in Sweden today. It is based on articles in two of the main liberal Swedish newspapers, Dagens Nyheter and Sydsvenska Dagbladet, and a liberal periodical, Neo.The purpose of this study is to analyze how the environmental problems that have been produced by the industrialised society, especially global warming, are seen upon in the liberal discourse in Sweden today. The theoretical point of departure is a discourse analysis that as a method seeks to analyze the material to reveal what assumptions the discussion departs from, and what assumptions the discussions reject.The thesis concludes that the main trends in the discussions are to position the environment against the financial system and state that the capitalist system is the only system that can solve the environmental issues. The existing environmental problems are not denied, but constantly belittled and only considered to be a problem if it poses a direct threat to humans. The solution for these environmental problems is believed to be the strengthening of the financial system and the development of new technologies..
Dark Side of Wonderland - en kort 2D-animation med syfte att väcka intresse för en online serietidning
My objective for this project was to create a short but thrilling 2D-animation
intended as promotion for an online comic book. The purpose of the project was
to learn more about animation and graphics, to further my artistic skills and
to learn how to work in Adobe After Effects. I also wanted to learn more about
scheduling, project methods and how to handle stress. During the ten weeks of
the project I have created the story, the storyboard, the character design, the
backgrounds and the animation. The voice over was recorded with the help of a
fellow student who also made the music and the sound effects.
Högfrekventa tryckvariationer under de senaste århundradena
Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.
ETT MED NATUREN. En ekokritisk studie av naturmotivet hos tre svenska skräckförfattare
Since time immemorial, nature has been conceived of as a female entity. This ancient concept is also a recurring element in contemporary Swedish horror fiction. The purpose of this thesis is to compare the feature of nature in the selected works of Anders Fager, Andreas Marklund and Frida Arwen Rosesund and in what ways these respective depictions rely on a tradition where nature is gendered female. The theoretical starting-point for this comparative study is ecocriticism and its subcategory ecofeminism, which are modes of literary criticism where the role of nature in general, and its female connotations in particular, are appreciated as significant literary features. For executing an analysis that goes beyond what is explicit, the exploration of these three writers? texts also adopts a psychoanalytical perspective.
Piano, gitarr och dragspel : Kön och instrumentval inom Eskilstunas kommunala musikskola och högre musiklinje åren 1980-2000
The aim of this study is to describe how nature is portrayed in swedish poet and critic Aase Berg?s two earliest poetry collections, Hos rådjur (1997) and Mörk materia (1999), and how it relates to notions of humanity, culture and civilisation. The concept of ?nature? is problematized in a short survey of how it has been used by and critizised in ecocritical literary theory, which is used as the main theoretical framework for this survey, with an emphasis on selected theoretical concepts by Donna Haraway. As a methodological starting point, ?nature? is tentatively defined as ?that which does not let itself be subsumed under the human, culture or civilisation?, and this definition is contrasted with how the concepts are handled in the texts.The investigation shows that the relationship of nature to the human is a fundamental theme that provides a structure for both poetry collections.
Den paradoxala kvinnan. En studie av Victoria Benedictssons och Mathilda Mallings kvinnoporträtt under 1880-talets sedlighetsdebatt
The aim of this master thesis is to examine how female identity is formed in two novels and two short stories from the 1880?s. As a framework we rely on the method outlined by Pierre Bourdieu when he approaches the cultural and social worlds through the concept of fields. To understand the female position during that time we use Michel Foucault?s work about the history of sex, Thomas Laqueur?s theories about the rise of sexes and Karin Johannisson?s study about the exploration of the dark continent (i.e.
