Being an architect I create spaces with roof, walls and fl oor. The availability of the essential materials to create such spaces is practically unlimited. The materials also play a significant part to the character of the created space. I hope to contribute to the general understanding of materials as elements in the design of urban spaces by having intensely explored one specific material in depth, pointing out its bad and good qualities. I am of the opinion that the reason for choosing a material shouldn?t be because of a shortage of knowledge, facts or references, but what character you want for the room. When travelling across Europe, it sometimes feels like clay paving is everywhere, but back in Sweden it is almost unseen of in modern landscape architecture.

Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.

Agricultural drainage ditches are links between fields, lakes and oceans, having the potential to transport e.g. sediment and nutrients. When in a good condition, drainage ditches can act as sinks for e.g. phosphorus and sediments and prevent eutrophication downstream. The aim of this study was to determine the condition of one agricultural drainage ditch and to come up with suggestions for appropriate measures. The aim was also to determine which of the ditch?s properties that were possible to evaluate visually, which processes they represented as well as which properties required complementary physical analysis. This in order to contribute to the work of developing a method for determining the status/condition of agricultural drainage ditches.

Syfte: Syftet med denna uppsats är att studera om förändringar i arbetet med rörelsekapital hade ett samband med lönsamheten i företag.

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

This examination studies the gender balance of contemporary art exhibitions in Sweden. To what extent genders are equally represented assumes to be based on how the curating process considers equality work. Three categories of art organisations are studied with the intention to determine differences in equality approach between the categories. Official documents of each organisation are examined to understand how they formally relate to equality work. Statistics of the actual gender balance of each organisation are produced based on the last two years exhibition archives.

This report is commissioned by the Water and Sewage Agency in The City of Mariehamn, Åland. The basic aim is to investigate positive or negative effects of a relocation of the sewage pipe from a wastewater treatment plant, Lotsbroverket. The environmental licence of Lotsbroverket is to be revised and The Environmental Appeal Board at Åland?s Government and Administrative Board has made demands that several possible locations in an outer water area should be examined. The present location of the sewage pipe is in Svibyviken, which has been classified as an ?inner water area?.The objective of this work is to study to which extent the nutrient loading from Lotsbroverket influence the environmental conditions in Svibyviken, and to investigate the suitability of different locations of the wastewater pipe from Lotsbroverket.The way a coastal area looks, i.e., its morphometry, determines to a large extent its ecological characteristics.

This thesis work has been carried out at the consultant company Pöyry Sweden AB in Norrköping, whom performs the task for E.ON heating Sweden AB, Händelöverket in Norrköping. The report shows methods to manufacture slurry consisting of fly ash and water. The slurry shall be pumped into several former oil storage rock shelters that E.ON has put into operation for the specific purpose. The ash mixture also develops hydrogen gas in contact with water.The work has aimed to produce different suggestions of methods and equipment that can be used for the objective. Mixing method and security issues were in centre while working with the suggestions.

This essay is about how organizations reveal their employees in the annual report. The purpose of this paper is to examine the extent to which organizations reveals their employees in the annual report, and the purpose has three questions: How do the organizations present their employees in the annual report? What do they choose to report? What motives lies behind?The problem today is that organizations can´t account the employees as assets, they can only be accounted as an expense in the income statement. This can lead to that stakeholders can´t convey an organization's "true" value.With a combination study, we examined how organizations certified by Investors in People presents the employees in their annual reports. In the framework, we have, among other things dealt with personnel mandatory disclosure in the Annual Account Act, the difference between private- and public sectors accounting.

A renewed application for environmental permit for the Hovgården landfill in Uppsala shall be submitted before December 2004, therefore the municipality of Uppsala needs improved knowledge of the contents, mostly organic compounds in the leachate and they also want to find a method to minimize the emissions of these compounds. The purpose of this study was to find a practical and economical method based on chemical oxidation using oxidants. The oxidants investigated are Fenton's reagent, hydrogen peroxide, Oxypro, potassium permanganate and potassium persulfate. The study was made on untreated leachate and leachate that has been treated in an aerated dam followed by sedimentation dams collected from the Hovgården landfill, and alson on sludge water from sludge storage cells. The effects of the five oxidants have been established by analysing the UV absorbance at the wavelengths 253,7 nm and 260,0 nm at different pH values. The UV absorbance was used to indicate the amount of aromatic hydrocarbons in the water. Also analyses of iron and manganese were done after the experiments with potassium permanganate, hydrogen peroxide and Fenton's reagent.

Vi lever i en värld där handeln mellan länder ökat kraftigt och blivit mer global. Avståndensom varor transporteras har blivit allt längre. På grund av förändringarna i världshandeln harefterfrågan på fler och längre transporter skapats. Till följd av detta har den ökande trafikenen allt större negativ inverkan på natur och människa, både globalt och regionalt, genomexempelvis buller och utsläpp av koldioxid. Idag står lastbilen för den största inverkan avtransportsektorns miljöpåverkan.Studie har haft till syfte att fylla i luckor i forskningen genom att utreda och jämföra EUR-palloch DACA:s plastpall utifrån deras användningscykel.

The negative trend of newspapers reading gives the owner of several paper manufacturingcompanies in the West worries. Producers should be more concern to strengthen their marketpositions in order to maintain profitability in the paper mills. Holmen Paper is a medium sizedpaper mill company with all of their production in Europe. Sales are mainly made to printingcompanies operating in European countries. In order to strengthen their economic strengthHolmen Paper needs to increase the market share in markets where they have the greatestprofit margins.

For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Since social media is used more today than just a few years ago, it is easier to share our lives to the public in just a few seconds. Social media is easily accessible on smartphones, tablets and computers which allow us users to use them whenever we want.Instagram is an example of a very popular social media today. In this paper we focus on how younger women think about their privacy when using and publishing pictures on Instagram. We have been using a qualitative research method in which ten people were interviewed. All respondents agreed that privacy is important when publishing pictures or videos on Instagram, but there were also some differences between users with public and private accounts.
