Riskbedömning vid Saltvikens kopparverk

AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

Produktivitet och lönsamhet vid skogsbränsleuttag i klena gallringar : en tidsstudie av Vimek 608 BioCombi i contortabestånd

The annual demands for forest fuels increases in Sweden. At present, large unutilized biomass resources is found in young, dense forests from which about five million oven-dry tonnes (ODt) (23 TWh) could annually be extracted as forest fuel. But harvesting small trees give high logging costs and new cost-efficient harvesting techniques are therefore required. The aim was to study the productivity of Vimek 608 BioCombi in forest fuel thinning of Lodgepole pine and to calculate the economy of the harvesting and estimate the thinning quality. The time study was performed in Åmarken in the county of Västerbotten.

Markavvattningsföretagens geografi och konsekvenser i Trosaåns avrinningsområde

Agricultural drainage is widely used to manage the amount of water in the ground in order to improve conditions for cultivation. However the effects of drainage companies on water regimes are considerable leading to runoff changes such as altered stream flows, peak flows and water levels. In a greater extent this could imply an increased risk for floods along affected watercourses. This study analyzes the extension of agricultural drainage within the drainage basin of Trosaån in Sweden by ArcGIS mapping. In a statistical analysis, historical variation in streamflow in relation to mean precipitation and mean temperature are investigated for the study area.

Organisationskultur ur två perspektiv : En jämförande studie av två etnografier ifrån socialantropologi och organisationsteori

This study aims to compare two ethnographies of organizational culture ? one from the discipline of Social Anthropology and one from the discipline of Organizational Studies ? considering their purpose, their method, and their concept of culture. Despite big similarities, or perhaps thanks to the similarities, some fundamental differences are made visible. The discipline of Organizational Studies has, compared to that of Social Anthropology, regarding the research method being used, less focus on, and less participation in, the informal social life of the organizational culture of the study. Regarding the concept of culture the Organizational Studies consider culture containing more of unity, stability and clear boundaries, compared to Social Anthropology.

Alnarps rehabiliteringsskog : ett gestalningsförslag

The understanding of the role of nature for rehabilitation of both physical and psychological afflictions has greatly increased in the last few years. There?s a lot of science that describes the healing effects of nature. The rehabilitation garden in Alnarp has contributed with very positive results from the treatments of patients with burnout syndrome. In the first stages of rehabilitation, the need for calm is very important and a demand-less and stress-free environment is of essence.

Vem håller i taktpinnen i krisberedskapsarbetet? - En studie av risk- och sårbarhetsanalyserna i länsstyrelserna

Crisis management planning is a relatively new policy area in the European countries. It has materialized since the fall of the iron curtain and because of the increased interest to prevent wide-ranging national emergencies. In Sweden, the county administrative board has a key obligation to perform risk analysis guidelines. This assessment involves identifying crisis, planning response to the crisis and, if necessary, confronting and resolving the crisis in the geographic area of the region. The purpose of my thesis is to examine if there are any differences in crisis management planning between the county administrative boards? risk analysis guidelines.

PPM - Passivt Placerande för Många : En analytisk studie av premiepensionsspararnas avsaknad av strategier för fondval

Introduction: In 1998, the pension system was changed and the so called PPM system was introduced. The PPM system is partly fund-based, partly distribution-based. There are approximately 700 different investment funds to choose between, at a maximum five for each individual. For persons who are not familiar with the financial market, the choice might be difficult. The lions? part of the investors do not seem to have an active strategy.

Miljöcertifieringssystemet BREEAM ? En studie av processen och dess effekter

Denna kandidatuppsats behandlar miljöcertifieringssystemet BREEAM med fokus på processen och systemets effekter. I studien har pågående BREEAM-projekt i Sverige studerats för att undersöka vad som görs specifikt vid en BREEAM-certifiering, vad det kostar samt vilka nyttor en BREEAM-certifiering genererar.Bygg- och fastighetssektorn står för en betydande del av miljöpåverkan i Sverige idag och förhoppningen är att miljöcertifieringar av byggnader kan minska miljöbelastningen. Studien visar på att det finns en växande efterfrågan på miljöcertifierade kontor och lokaler från hyresgästen trots att innebörden än är något oklar.BREEAM är relativt nytt på svenska marknaden och behöver fortsätta att utvecklas och anpassas. Ett svenskt företag, med en redan god intern byggstandard, behöver dock inte göra några större åtaganden för att nå ett bra betyg i BREEAM. En BREEAM-certifiering intygar att en byggnad håller en bra nivå miljömässigt, visar att företaget är på väg åt rätt håll och hjälper till att strukturera upp miljöarbetet under ett byggprojekt.

Comparison of Different Electrophoretic Methods for Haptoglobin Phenotyping and an Investigation in Patients with Abdominal Aortic Aneurysm

Haptoglobin is an acute phase protein with important biological role because of its capacity to bind to haemoglobin. Haptoglobin exists in three major genetic polymorphism types: Hp1-1, Hp2-1 and Hp2-2, the distribution of which has been associated with abdominal aortic aneurysm (AAA), an asymptomatic aortic disease common among men older than 65 years.    Five different electrophoretic methods were tested according to their ability to separate the haptoglobin phenotypes. The detection was based on a produced hemolysate of blood in which haemoglobin binds to haptoglobin thereby forming a complex that can be detected by specific haemoglobin staining using TMB-dihydrochloride and hydro peroxide as substrate resulting in an azure-green color of the bands. Samples from 15 patients who had suffered surgery for not broken AAA, that is more than5.0 cmaortic diameter, and 15 samples from matched controls were analyzed.    Among the five tested electrophoretic methods best migration and separation was seen on the pre-cast agarosgel Hydragel HR on the instrument Hydrasys. The other four methods gave less successful results.

Landsbyggdens egnahem i Malmöhus Län 1905-1040. En studie av markförsäljningen till fastigheter som beviljades egnahemslån

During the period 1905 to 1940 it was possible to get a loan from the state to buy land and build a small farm or a house in rural areas. This loan act and its effects have been studied earlier in different ways, but never as a total study for a geographic region. The region Malmöhus Län has been chosen. The purpose of this paper is to study in which parts of the area loans were taken and who sold the land that was used for these purposes. Earlier studies have looked at a larger geographical area for some specific years.

Europeisering och politisk integration av nationella politiska partier : En studie av Vänsterpartiets och Miljöpartiets utveckling i synen på det europeiska samarbetet 1987-2010

This paper examines if European integration has had an impact on national political parties by looking at the stances of the Swedish Green Party and the Left Party on the issue of the European Community and the European Union over time. With the development of the European Community and the European Union, national political parties face the challenge of an emerging political arena. European integration research has recently become more involved with what is called europeanization and political integration within the member states them self, this paper aims to provide further leverage to the thesis that national political actors undergo some degree of europeanization and are politically integrated in the EU, by examining manifestos of two historically eurosceptic Swedish political parties. The theoretical framework provided by neo-functional integration theory as well as europeanization is used to examine the empirical material in order to see if the political parties at the focal point of this study can be said to have undergone a change in political policy regarding the EC and EU, both in quantity and content. The analysis show that indeed both parties has undergone a change and what might be considered a europeanization, considering that the presence of the EU as a political issue seem to have risen in prominence and importance in the examined manifestos.

Diskussion om röjningsrösen : med teorier om gravrösen i fossil åkermark och skärvstenshögar

This paper aims to investigate the connection between clearance cairns and burial cairns. From this point of view I try to answer the questions why they are built in the same area and why these two different types of cairns are so similary constructed. Further I consider different theories about mounds of fire-cracked stones..

Huntingtons sjukdom och dess cellulära mekanismer

De gamla ängs- och betesmarkerna hör till Sveriges artrikaste biotoper, ofta med en mycket hög arttäthet inom både flora och fauna. Ängs- och betesmarker har minskat kraftigt under det senaste århundradet vilket har lett till en utarmning av den biologiska mångfalden. Denna undersökning sker i samarbete med Täby kommun och syftet är att undersöka 10 olika ängs- och betesmarker för att få en uppdaterad bild av hävdtillståndet och vilka åtgärder som är mest lämpliga att sätta in.Detta arbete avser att fungera som en grund där framtida undersökningars resultat kan jämföras med för att se vilket resultat de insatta åtgärderna gett. Metoderna som använts är en allmän artinventering, art/area analys och successionskategorier utarbetade av Urban Ekstam samt studier av indikatorarter och lokalernas allmänna utseende exempelvis om mycket gammalt gräs finns i lokalen. Art/area- kurvorna studeras vilka genom sin lutnig och form visar vilken arttäthet som råder i det studerade växtsamhället.Flera av de undersökta lokalerna visar tecken på igenväxning och domineras främst av konkurrenskraftiga kvävegynnade arter. Dock finns ofta mindre bestånd kvar av hävdgynnad flora vilka skulle få en chans till expansion om en intensivare hävd sätts in.

LiDAR-bildanalys av flutings i södra Norrbotten : Kartering och datering av avvikande isrörelseriktningar

The aim of this study was to map and date glacial flutings with ice flows deviating from the predominating northwesterly ice flow direction in the southern part of Norrbotten County in northern Sweden, and also to investigate if parts of the glacial landscape are older than previously thought. The traditional view is that most landforms in the area were formed during the late Weichselian (W3). Analysis of the new high resolution elevation model (2 m grid) derived from laser scanning was performed after treating the data with a hillshade tool in ArcMap to reveal terrain features such as flutings. The analysis resulted in a map showing four main groups of deviating ice flows (N-S, NO-SV, SO-NV and S-N) and several westerly ice flows. The majority of flutings with deviating ice flows were found in low terrain.

Val av område och områdesskydd för Natura 2000 med skogshabitat : En jämförande studie av fyra län i Sverige

The Natura 2000 Network is one of the European Unions many tools concerning nature conservation, and is without comparison the premier contribution when it comes to halting the loss of biodiversity. This essay is a case study on how the regional work with the Natura 2000-network has been carried out in four different counties. These counties are Södermanland, Västernorrland, Jämtland and Örebro. They have been compared based on the theoretical concept of sustainable development. This essay describes how the officials in the County Administrations view the regional implementation of Natura 2000 when it comes to the selection of Natura 2000-sites with forest habitats and the creation of an additional protective measure.
