Kartläggning av föroreningars förekomst och spridning i Gräsötippen enligt MIFO

It is estimated that 22 000 contaminated areas exist in Sweden today. In order to classify the risk of contaminant migration from these areas and to prioritize which of these contaminated areas should first be treated, the Swedish Environmental Protection Agency (EPA) has designed a method, for the investigation of contaminated areas (MIFO). One of these contaminated areas is the landfill Gräsötippen outside Köping. The landfill has been used by both Yara AB and the Köping municipality between the years 1945 and 1975, and both industrial and household waste have been deposited there. The aim of this report is to survey which contaminants that can be found in the soil and water in the landfill Gräsötippen and to evaluate the migration of these contaminants.

Utvärdering och åtgärdsförslag av energianvändning i kontorsbyggnad

AbstractEmbla 5 is an office building which has done a large improvement. The clients of this building has made an order of WSP and the student Anders Kempe to calculate the use of energy for the building, and after that result proposing further measures which can decrease the energy use of Embla 5.The ground for this report is when calculation of the present energy use of the building is stated. To make that information of a number of parameters such as envelope, the heating system and ventilation has been located and set in to the simulation program IDA ICE which calculate the energy use.To improve the energy use further this project has been concentrated to change the system of ventilation. Today the ventilation system is of the kind CAV (constant air volume) and the air flow is dimensioned for after recommendations from BBR and Arbetsmiljöverket in the office spaces. Consider that Embla 5  is an office building where the people only staying for 8-10 hours/day so was the ide to see how much energy saving if the air flow is reduced the time people not being in the building.

Att bygga ett bibliotek : En studie av funktion och rörelse i tre nyinrättade biblioteksbyggnader - Kungliga tekniska högskolans bibliotek, Sambiblioteket i Härnösand och Vitterhetsakademiens bibliotek

A large part of research about libraries and library buildings in Sweden has been focused on how the building looks not how it functions with the library. The aim with this master?s thesis is to study how a library building is functioning and how its users are experiencing it. This is studied in three libraries, Kungliga tekniska högskolans bibliotek, Sambiblioteket in Härnösand and Vitterhetsakademiens bibliotek. With the questions of how they were planed, what did the libraries want from the new building and which of these demands were realized.

Leveranslogistik på byggarbetsplatsen

Problem: How do delivery logistics work in practice at the building site? Where are the big problems? How to make building logistics more effective? Do the site management and the haulers agree about questions concerning both parties? What is possible to gain by using better logistics? Is it possible to gain time with better logistics and by that reducing the costs? Purpose and aim: The purpose is to discover if there are any disagreements between the site management and the haulers. If disagreements occur they will be examined and probable measures based on the problems will be suggested. Another intention is to bring key ratios concerning time spent for deliveries forward. One aim is to update a similar report made in 1972.

The theory used fore the examination isstate-building, whith an alingnment of state-building trough the international community.The second part of the essay examine the ideas of the High representive (HR) trough threedifferent dimensions. The idea-analysies search to present the core of ideas of OHR, nationalparties and the reconstuction of media.

Metodutveckling för analys av klorfenoler i jord samt analys av förorenad jord från ett sågverk

In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.

Framtiden för gamla Habo ullspinneri

This report presents an investigation and a new design of Habo Ullspinneris old industrial premises. It is based on the owners visions and wishes, two questionnaires and also considering of the historical value.Habo Ullspinneri was founded in 1882 by Frans August Johansson and was moved to the location it has today, near Hökån in Habo, three years later. The electricity that the machines in the industry needed was extracted from the small river that is placed under the building. In 1960 there was a fire and the result became the end of the industrial activity that had taken place in the building.There is no steady activity in the building at the moment. It is nowadays temporarily used as an agriculture museum and as a store room.

BIM-projektering i praktiken

The use of CAD, within the building industry came strongly, during the 1980?s and the 1990?s. The development has since then rapidly progressed and the using of 3D-models has in addition increased. We are now at the edge of next step of evolution. BIM, Building Information Model(ing), is here.

Så långt inuti, näst intill borta

Through wing pattern, posture and movement, a harmless moth of the family Brenthia imitates an eight-eyed jumping spider. When an octopus of the species Thaumoctopus mimicus sense danger it can alter its appearance to that of a venomous sea snake. They are both drawing attention to themselves. Nevertheless, and because of this, they are protected. The mechanism is called mimicry.

Siktning som saneringsmetod för metallförorenad mark

Toxic metals contaminate soil worldwide and thus serve as sever environmental threat. Therefore the purposes of this study were to investigate in which soil fractions that different heavy metals (Fe, As, Cu, Zn and Pb) could be found in contaminated soils and if it is possible to use sieving as a method for decontamination. Soil samples were collected from three different locations, the Nasa silver mine, the Blaiken-mine and Svalget environmental station. The samples were oven dried and later on sieved into six different fractions 8mm, 4 mm, 0.5 mm, 0.250mm, 0.063 mm and <0.063 mm. The fractions 4 mm, 0.5 mm and <0.063 mm from each location were analyzed in an x-ray fluorescence detector.

Go Down Arts Centre : Nairobi, Kenya

The Go Down Arts Centre is a proposal for a new building to an existing organisation in Nairobi, Kenya. The proposal relates to the scale of the city by making a statement on a future urban path, and by welcoming the city in to the building. The proposal houses both activities affiliated to Go Down, such as studios and rehersal rooms, as well as opportunities for the visitor to meet and interact with the culture produced at Go Down, both in formal and informal settings. The building is closed to its surroundings, apart from a grand entrance towards the urban path. There, the city passes through the building to an inner courtyard, where the communication to all the rooms and activities takes place.

Ljus i butiksmiljö : Upplevelsen av ljus och exponering av produkter

This thesis examines how to improve the exhibition of products within retail for clothes and gift articles. The purpose is to investigate and test how light sources and different directions of light affect how the products are perceived regarding their exhibition. Our question formulations are:To what degree does the level of light in combination with the background of the interior design of a shop affect whether a product is perceived more or less attractive?What can we recommend to make the exhibition of products more attractive? From our observations shops nowadays have relatively high levels of light when they expose products on vertical areas. We have looked on the recommendation from ?Energimyndigheten? in order to see what they think is important when designing retail lightening.

Nyutveckling av bakdörrar vid Sapa Building System AB

Sapa är en av de största tillverkarna i världen av aluminiumprofiler. Sapa Building System AB är ett dotterbolag till Sapa group och är en av de största leverantörerna i Europa på byggsystem. Några av deras produkter är bakdörrarna RD 3010 och RD 3020 för lastbilar, släp och trailers som från början var ämnade som sidodörrar. Som bakdörrar är de överdimensionerade då sidodörrar hade högre hållfasthetskrav. I dagens läge väger och kostar de mer än nödvändigt där av önskar Sapa Building System AB en nyutveckling av bakdörrarna.Målet är att omkonstruera bakdörrarna RD 3010 och RD 3020 så att de blir lättare, smidigare och billigare genom att konstruera en ny kantskoning till Sapa Building System AB:s befintliga aluminiumlämprofiler.Arbetet har resulterat i att ritningsunderlag för nya profiler har tagits fram där man valt att limma ihop dörrarnas delar istället för att nita.

Klimatskärmens funktion : En jämförande analys av projekterade nybyggnationer i Östra Salabacke, ur ett energi- samt fuktperspektiv

The design of the building envelope affects the energy consumption of a building. As the energy requirements for new buildings are becoming more demanding, the performance of the building envelope must be improved. Energy efficiency and durability are important attributes to consider.This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new, climate smart, residential area in Uppsala, Sweden.Studies and analyses on energy consumption and moisture transportation were made.
