Det a?r sva?rt att sa?tta ord pa? vad man menar na?r man pratar om musik. Jag a?r intresserad av varfo?r det sa?llan ga?r att finna definitioner av genrer na?r diskussionen om dem a?r sa? stark, speciellt na?r det ga?ller snarlika genrer som troligtvis a?r uppdelade av en eller flera anledningar. Syftet med min underso?kning a?r att utveckla vidare kunskap om vilken betydelse det har att skilja pa? tva? snarlika subgenrer inom samma metagenre.

A major issue that has been a subject for quite some time is whether there will be a scarcity of metals in the bedrock in the future and whether or not we might end up with a problem similar to that of the big oil crisis in the mid-seventies. Following the oil crisis many oil companies started up with risk management to control future risks. This work presents how Swedish mining companies work with risk management to handle risks that might come up in the future due to metal scarceness. How Swedish mining companies look at the possible metal scarceness and if they use risk management in their decision-making process is studied. By doing interviews with Swedish owned mining companies it was found that the mining companies did not see the future metal scarcity as a risk, even though 2/3 of the companies acknowledged the scarceness to be a reality.

This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations.

Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.

A research of 14 toxic affected study sites in Sweden showed a significant increased proportion of deformed diatoms. The six metal polluted study sites in the region of Dalarna showed a 4, 2% average of deformed Fragilaria (deformed diatoms reference sites, 0, 1%). The results also indicate a significant increased proportions of deformed diatoms in the eight pesticide polluted sites in the south and middle of Sweden, compared to the reference sites, howsoever the toxic content was low. The results indicate that there are no lager differences in neither teratological forms nor variations that segregate metal polluted and pesticide polluted shells. One of the reasons may be that both heavy metals and pesticides can affect the development of the diatom shell..

Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.

This project includes development of new packaging for dry spices and an investigation of how to automate the production line. The preliminary investigations show needs of an environmental friendly packaging possible to re-close. After screening for suitable materials three concepts were developed, a stand-up pouch, a plastic jar and a metal can. The pouch was excluded in a concept choosing process. In this process it was also decided to further develop the metal can concept.

The aim of this study was to examine the amounts of heavy metals in the sediment of a wetland constructed for stormwater treatment. The wetland is called Vattenparken and is located in the city of Enköping. The heavy metals which were analysed were Pb, Cd, Ni, Zn, Cu, Cr and Hg. The total metal concentrations were determined using HNO3 chemical extraction. From 8 sampling sites 5 sediment cores were taken.

Syftet med mitt arbete är att arrangera om två operaarior till metal och spela in både originalversioner och metalversioner för att sedan kunna jämföra dem med varandra. Frågeställningarna jag utgick ifrån var: " Hur ska jag kunna skriva om två operaarior till trovärdiga metallåtar, utan att bruka allt för mycket våld på originalen?", "vilka skillnader gör jag i min sångteknik och interpretation, om jag ens gör några, i de klassiska versionerna jämfört med metalversionerna?", "vad är det för skillnader och likheter mellan de klassiska förlagorna och metalversionerna?" och "vilka val gör jag i arrangeringen och varför?".Ariorna som jag har valt att arrangera om är Dido's Lament ur operan Dido and Aeneas av Henry Purcell och Svegliatevi nel core ur operan Giulio Cesare in Egitto av Georg Friedrich Händel. Den konstnärliga delen av mitt arbete har bestått av fyra delar; en inspelning av de klassiska versionerna av ariorna, själva omarrangeringsprocessen från klassiskt till metal, inspelningen av metalversionerna och jämförelsen mellan de klassiska versionerna och metalversionerna. Projektet visade att det sällan blir som man har tänkt sig och jag reflekterar även kring hur det kom sig att de förväntade skillnaderna i min sångteknik från klassiskt till metal aldrig riktigt uppstod, men att interpretationen var annorlunda i de olika versionerna.

Uvån Hagfors Teknologi AB (UHT) has developed a process ? GRANSHOT® ? for quicksolidification of metals in water baths. In the process liquid metal is splintered ? granulated ?into small drops. The drops are rapidly cooled in a water bath where all the heat energy from theliquid metal is transferred into the water.

Denna studie har som mål att undersöka hur produktplaceringar i spelet Metal Gear Solid 4 kan ha för roll i narrativet, vad dessa tillför spelet och vilken roll de har för karaktärerna i berättelsen. Studien undersöker även om dessa produktplaceringar visas på ett sätt som förstärker produktens eller varumärkets status men även för att se om stereotyper nyttjas för att upphöja deras effekt.Denna studie bygger på en kvalitativ textanalys med semiotiska och narrativa inslag där jag tillsammans med valda teorier om bland annat narratologi och produktplacering kommer att svara på uppsatsens frågeställning:Hur används och integrerar varumärken/produkterna med narrativet och karaktärerna i Metal Gear Solid 4?  Resultatet visar att de produkter och varumärken som finns med i spelet har varit viktiga för både narrativet och karaktärerna. Dessa produktplaceringar har bland annat gjort spelets berättelse och dess karaktärer mer verkliga då de har hjälpt att skapa en länk mellan fiktion och verklighet. Produkterna har spelat en stor roll i narrativets story och händelseförlopp då de har varit viktiga instrument som har underlättat spelandet och fört narrativet framåt samtidigt som de har använts av spelets karaktärer och gjort det möjligt för dem att kunna uppnå det slutgiltiga målet i narrativet, vilket är som många andra berättelser idag, världsfred..

The purpose of this study was to investigate how elevated levels of heavy metals affect the faunal species composition, abundance and species-diversity. The bentic macroinvertebrate fauna in the highly polluted lake Tisken was compared with the bentic macroinvertebrate fauna in the unpolluted lake Varpan. Mine wastes account for most of the metal that is discharged into Tisken. The hypotheses was that the heavy metal pollutions in lake Tisken influenced the species composition, abundance and diversity of the macroinvertebrates. Twenty samples were taken in both sites.

Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.

Uppsatsen granskar det spänningsförhållande som existerar mellan Hårdrockens uttryck och den oinvigda allmänhetens moralpanik. Genom självpresentation och smakdistinktioner undersöker den också hur Hårdrocken idag har positionerat sig som en etablerad kultur med ursprung och tradition. På så sätt behandlar uppsatsen vad och vem som definierar Hårdrockens kulturella värde och position. Undersökningen görs genom en textanalys av den svenska hårdrockstidningen Close-Up Magazine. Uppsatsen granskar även hur tidningen positionerar och presenterar sig som betydande aktör inom Hårdrockens verksamhetsfält..
