Mineraliseringar utmed REE-linjen i sydvästra Bergslagen

This paper briefly summarizes Bergslagen as a bedrock province in order to give background to the genesis and presence of REE-bearing minerals (short for Rare Earth Elements) in the region. These mineralizations mainly occur along the REE-line, a line aproximately a hundred kilometers in length between Norberg in the north and Nora in the south with a width of a few kilometers. Situated in the southwest of Bergslagen it is currently one of only a few places in Sweden where REE-bearing iron oxide mineralizations are potentially economically viable for mining. Ore microscopy has been conducted in order to characterize an ore sample from Myrbacksfältet, one of few sulphide rich iron oxide mineralizations within the REE-line. Additionally, an electron microscope analysis of a sample from Stålklockan, a suspected REE-bearing mineralization also within the REE-line was confirmed by EDS (short for Energy Dispersive Spectrum) analysis.

Numerisk modell för global transport av spårämnen i atmosfären

The aim of this project was to develop a numerical model simulating the global transport of air pollution. The model currently used by SMHI, the Swedish Meteorological and Hydrological Institute, was intended to perform such simulations at regional scales. However, the usage of a grid based on longitudes and latitudes makes this model work poorly in global simulations. The problem with this grid is that the nodes are concentrated near the North and South Poles. Due to this characteristic, the Courant, Friedrich and Lewy-condition for numerical stability puts a sharp bound on the timestep length.

Laboratory adjustment to the new regulation on classification, labeling and packaging of substances and mixtures.

The United Nations has, during many years, developed a model for a globally harmonized system for classification and labeling of chemicals, with the aim of it becoming a global standard. This system is implemented in the European Union through the CLP-regulation and is now working parallel to the existing directives until 1st of June 2015, when all the new classifications of substances and mixtures must be completed. The aim of this project was to adjust the laboratory to the new legislation, through inventory of stored chemicals, update the list of chemicals and perform self-classifications of mixtures. The work included handling of about 650 different chemicals with varying hazard classifications and search for information in corporate websites and chemical databases. This resulted in a new and complete list of chemicals stored and used in the laboratory and, in addition, an example of how to make a self classification of a mixture.

Relation utan oberoende? : En studie av sex mindre revisionsbyråer

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.

Ett märkligt adjektiv på en medborgare : En intervjustudie av det praktiska medborgarskapet som identitet och ideal

The aim of this essay is to explore the lived citizenship and its ideal. First, the form and expression of citizenship practice and ideal is explored through a qualitative interwiev study of ten citizens in the southern suburbs of Stockholm. The perception and expectations of the nature of citizenship, presented by the informants, is then compared to their citizen ideal, as well as to the ideal presented and promoted by the Swedish government. The point of departure is theory of democracy. The essay calls attention to an observed lack of empirical studies in the field of deliberative theory of democracy as well as studies that more broadly bring the theory down to empirical earth.

Hållbar växtnäringshantering i Stockholms län : En aktörsanalys

Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.

ISO14001:2004 : ett humanekologiskt verktyg?

ISO14001:2004 : A Human Ecological Tool?This is a study by means of litterature analysis and personal experience to find out wheather you could call ISO14001:2004 a Human Ecological tool. The ISO14001 is an environmental management system. I'm approaching the issue from a users' perspective and putting my experience of implementing the ISO 9001 at my work to good use. Though my personal experience is limited to the implementation of the ISO 9001, it is quite relevant to the task since the update of 2004 the ISO14001:2004 is brought closer to the ISO 9001 standard in many ways.

Putting the Al in moral : En deskriptiv moralanalys av Al Gores bok Earth in the balance

Uppsatsen är en kvalitativ intervjustudie, med barnperspektiv som metodologisk utgångspunkt. Syftet är att infoga några barns röster, angående vem som stör(s) i det offentliga rummet.Intervjuerna genomfördes våren 2008 i Stockholmsområdet, med ett urval av fyra barn i nioårsåldern. Gruppintervjuerna skedde vid två tillfällen och formen var halvstrukturerad.Olika teorier tillämpas utifrån en problematisering av vuxenmakt, där barnens reflektioner relateras med positioneringar och normer. Teoretiska begrepp från queer- och maskulinitetsteori används för att se till maktdynamiken, mellan barn och vuxna. Det framkommer att de intervjuade barnen använder sig av olika motståndsstrategier, för att handskas med rådande vuxenmakt i det offentliga rummet.

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.

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.

Omvårdnadsåtgärder som främjar sömnen hos patienten : En systematisk litteraturstudie

The study is done as an improvement project.Methods: The study was conducted by performing semi-structured interviews with eight close relatives to patients on a general psychiatric ward. The interviews lasted for 20-40 minutes.Results: The result shows that relatives are satisfied with the way they are meet by the staff on the ward, that they appreciate staff that are open, down to earth and are inviting to form a good relationship.

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..
