Känsla för metal : Att gestalta känslor med hjälp av symphonic metal

Syftet med det här arbetet var att gestalta fem olika känslor inom genren symphonic metal. Därigenom ville jag avgöra vilka verktyg jag kunde ha nytta av i framtiden för att gestalta känslor musikaliskt och vilka skillnader som finns mellan att gestalta olika känslor. För att göra detta använde jag mig av referenslyssning av tio låtar plus några orkestrala stycken per känsla. Resultatet av lyssningen, tillsammans med olika låtskrivningstekniker, litteratur, Kirnbergers intervallkaraktäristik och Matthesons tonartskaraktäristik, användes till att skriva och arrangera mina fem låtar. Resultatet blev att jag hade lyckats skildra känslorna bra med den metod jag hade använt, men att intervallkaraktäristiken och tonartskaraktäristiken var onödiga; det skulle räcka med mina kunskaper som jag hade förvärvat under utbildningen, referenslyssning och min känsla som låtskrivare. Jag kunde inte heller urskilja några skillnader mellan att gestalta de olika känslorna; metoden var universellt tillämplig..

Att definiera och skilja på snarlika subgenrer : Tillämpat på death- och black metal

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.

Betyg och identitet : En undersökning av elevers föreställningar om betyg

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.

Dietary intake of zinc and iron within the female population of two farming villages in the Red River Delta, Vietnam

In many developing countries, among them Vietnam, contamination of agricultural land is a major issue that has public health implications. A fast growing population, rapid urbanization and industrialization have led to air and water emissions of potentially toxic elements (PTEs), such as cadmium (Cd). Earlier studies have shown that individuals with low iron (Fe) and zinc (Zn) status absorb larger quantities of Cd than those of adequate nutritional status. The purpose of this study was to investigate and compare the Fe and Zn intake from the foods consumed by women (15-45 years) in selected households in two agricultural villag-es in the Red River delta in Vietnam. In one of the villages the residents were involved in metal (mainly Fe) recycling activity, whereas in the other village the residents had agricul-tural production as main source of income. Interviews, followed by food intake calcula-tions, were performed.

Finngruvan - Uppföljning av vattenkvalitet, analys avavrinning och recipienter i området efter gruvdrift

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.

Kiselalgernas missbildningar under toxiska förhållanden

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..

Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Utveckling av förpackningssystem för torra insatsvaror i livsmedel

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.

Retention av tungmetaller i en anlagd våtmark : studier av Vattenparken i Enköpings kommun

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.

Från opera till metal: En förening av två till synes oförenliga världar

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.

Kartering av markföroreningar inom Skutskärs Bruk samt utvärdering av spridningsrisker enligt Naturvårdsverkets MIFO fas 2

With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.

ENERGIÅTERVINNING I GRANSHOT® - PROCESSEN

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.

Riskbedömning av miljö- och hälsoeffekter efter järnhanteringen i Strömsbergs bruk

Risk assessment of effects on the environment and health outcome caused by the iron industryLina LöfqvistIn Sweden you can find lots of contaminated areas, which can create problems for both humans and nature. To reduce the long-term contamination grades, Naturvårdsverket have created a report with regard to the contaminated sites. This builds on the ?Method for Inventories of Contaminated Sites? which is abbreviated MIFO. The aim of MIFO is to achieve better environmental planning in Sweden.
