En geokemisk kartering över området kring Nasa silvergruva : Effekterna av historisk gruvdrift i svensk fjällmiljö

The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.

Ledarskapsskillnader mellan ofentligt och privat anställda ledare : När sektorstillhörighet inte längre är relevant

The Public vs. private movement has over the past decades identified numerous significant differences between public and private organizations. The observed differences covers almost every field in administrative economics ranging from organizational structure, management accounting, goal-setting and in the past few years even leadership. Strangely, in the majority of these studies little or no regards are given to organizational characteristics or fundamental differences between compared organizations and if these organizations really are comparable when studying the effect of sector.The aim of this study is to compare leadership in relatively similar organizations from both the public and private sector and so clarify if earlier identified differences in leadership styles still surface when leaders working with approximately the same thing in a similar work context are studied.A sample of 348 Swedish principals was drawn from both municipal and private elementary schools. The respondents answered a web-based survey based on the CPE-model resulting in leadership styles mapped according to three orientations: change, production and employee.

Tankar kring Torsk : Isotopanalyser av torskkotor för att undersöka vikten av torskimport i medeltida Sverige

This essay discusses the import of cod (Gadus morhua) in Sweden during the Middle Ages through isotope analysis of cod vertebrae. The isotope analysis is used to trace the cods origin to either the Baltic Sea or the Atlantic Ocean. The bones were subjected to d13C, d15N and d34S analysis; 64 of  the analyzed bones met the quality criteria. The isotop data showed that import of Atlantic cod was significant in medeval Sweden. The analysis suggests that there is no specific time or event that the sites start to import cod but this varies from site to site. .

Passivhus : En jämförelse mellan olika byggnadstekniska lösningar för ytterväggar

This report aims to examine the design of a passive house. The design addresses the selection ofmaterial, sizing and selection of both building services systems and building technical features suchas load-bearing framework and moisture control. Interior layout is designed for a family of twoadults and one child.A big part of the report is devoted to an in-depth comparison of three different wall constructions ofpassive house standard. The structures that have been compared are a lightweight timber structure, aheavier concrete structure and a sandwich wall of the brand Weber Leca. The report covers variousaspects such as air flow, wall thickness, the risks associated with the construction, U-value, thermalbridges, power consumption, price, and assembly costs.

Ekonomisk och teknisk uppföljning vid anläggningsprojekt : För möjlighet till bättre erfarenhetsåterföring

Due to the obvious fact that one can never be hundred percent sure of what's hiddenunder the ground surface, construction work is naturally hard to project.However, many of the work methods are executed in the same way on variousprojects. The department of construction work at JM AB region öst describes a lackof follow-ups and feedback between the calculators and production managers.In this thesis we have studied the communication between these groups and alsohow they share experiences and knowledge. In order to get the full pictureof the day-to-day operations we used three methods to gather information. Studyingliterature gave basic knowledge of theories about feedback, and thenecessity of working with giving feedback. In order to understand the process ofconstruction work we made several interviews, both structured and nstructured.

Vätskebehandling inom brännskadevård

SummaryPatients with burn injuries involving more than 20 percent of the total body surface area lose a lot of fluid and are in the risk of developing a severe hypovolemia. Fluid resuscitation is a corner stone in burn care and is important for preventingfurthercomplications. The most common resuscitation formula is the Parkland Formula. Hourly urine output is a measure used to evaluate if the fluid given is sufficient enough to maintain a sustainable tissue perfusion. Inhalation injury, abuse of alcohol and drugs are some of the factors that may increase the amountoffluid needed.

Bottensubstrat och dess inverkan på reducering av BOD5, COD och TKN i lakvatten genom konstruerade rotzonsanläggningar : En pilotstudie vid Univates, Lajeado ? RS Brasilien

Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice.  In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.

Tillverkningsanpassning av produkt för kostnadsreducering : Nya tillverkningsmetoder och verktygsparametrar

This thesis describes redesign and adaption of a products housing. In order to make it more economical to produce at a lower production volume. The thesis is based upon a prototype that a previous student developed for injection moulding. The goal is to find alternative manufacturing methods, but also to identify parameters that affect the cost of the injection moulding tool.The housing must be tough in order to protect the circuit board inside. But at the same time it must allow sound, light an electrical communication to pass through.

Spår av Senmodernitet: hur den sentida forskningen inom socialt arbete använder sig av teorier kring senmodernitet

The purpose of this study has been to investigate how frequently, and in witch ways, theories concerning the "late-modern" society are being used in the contemporary research of social work. My thesis is that theories concerning the late-modern society could be useful in social work research, foremost to shed light on, and broaden the understanding of, dilemmas and problems that are specific to the contemporary society. In the study I'm investigating all doctoral dissertations on social work written in Sweden between the years 2003 and 2006, and to execute the study I've applied a text analysis method in four steps. Simplified the four steps of the analysis can be said to investigate, if, how frequent, and in what way theories on the late modern society is being used in social work study. I'm also specifically investigating how problems exclusive to the late-modern society is being taken under consideration in the dissertations.In the analysis of my results I take a critical theory approach and I also discuss if theories on late-modernity is to be seen as a paradigm in the field of social work science.

Camp Vamp - Att ljussätta en dansföreställning med skiftande förutsättningar

I work on a lighting design for a dance performance to be on tour. A lighting design adapted for three different conditions was made: - One comprehensive where I allow myself a great deal of creative freedom, adapted for the stages with major technical conditions. - One smaller version for stages with less equipment and with less time for preparation on site. - One design for very simple conditions. I also examine the specific differences between typical theatrical lighting design and typical dance lighting design, and the best way to prepare for the hands-on stage design phase..
