Anaerob psykrofil behandling av hushållsavloppsvatten i UASB : Utvärdering av kapaciteten hos en två-stegs UASB-reaktor för behandling av hushållsavloppsvatten

Hammarby Sjöstad is a new district in southern Stockholm. A main objective with the Sjöstad project was to halve the environmental impact compared to other construction work. The environmental goals involve a halved water consumption rate, a local treatment of storm water and trials aiming to extract nutrients from the waste water. Sjöstadsverket is an experimental treatment plant used for testing new treatment processes for domestic waste water from Hammarby Sjöstad. The results are to be compared with the conventional process used at Henrikdals treatment plant today.

Utfackningsvägg av lättbetongblock i passivhus

AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.

Recovering common ground : landscape architecture as a tool for post-conflict recovery and spatial reconciliation in divided cities

The following chapters examine landscape architecture which engages in contested territories with an emphasis on the way in which landscape architecture can engage with the issues of divided cities or landscapes with similar social, cultural and physical properties. The project focuses specifically on the potential landscape architecture has for promoting or aiding in the reconciliation process of these areas, by examining the following questions. How can landscape architecture be used to benefit the peace building process of divided cities and landscapes? How can landscape architecture be used in the process of promoting spatial reconciliation in the case of Belfast? The investigation begins with a description of the background to the project in Chapter 1, which functions as a brief introduction to the urban phenomena that is divided cities. It then goes on to introduce the different methods and data employed in order to answer the research questions in Chapter 2. After introducing the problem and the methodology, a global overview of divided cities is performed in Chapter 3. This chapter is divided into two sections.

Uran i dricksvatten : litteraturstudie om reningsmetoder samt pilotförsök med jonbytesteknik

Uranium (U) is a naturally occurring component in bedrock and under the "right" conditions it can dissolve and move into the ground water. Since many people in Sweden depend on drilled wells as their main drinking water supply, they may be exposed to the uranium in the water. Radioactive radiation is not the major concern associated with naturally occurring uranium. It is rather the chemical properties of uranium that make it a potential danger to human health. Uranium is proven to have toxic effects with respect to the functioning of the kidneys.

Effects of storage time, die channel length and moisture content on pellet quality of lodgepole pine (Pinus contorta Dougl. var. latifolia)

The use of renewable resources is rapidly increasing in Sweden, especially the use of fuel pellets. Through pelletizing the energy content per volume unit is greatly increased and the pellets are more homogeneous with regard to moisture content, particle size and density compared to unrefined fuels like forest residues and chips. For further development of the Swedish pellet industry, the use of different assortments from lodgepole pine (Pinus contorta Dougl. var. latifolia) is of particular interest, mainly because of its high volume production.

Fälttest av en ny metod att med objektiva mätmetoder karaktärisera egenskaperna hos ridunderlag- en pilotstudie. :

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

CFD simulering av kallras : Undersökning av temperatur- och luftbeteende intill höga glasfasader och i vistelsezon med golvvärme som en värmekälla

Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available.

Priset på åkermark : påverkande faktorer

The price of farmland has risen sharply in the last 20 years. This has led to discussions about what creates the value of farmland. The aim in this study was to try and find what factors are affecting the price on farmland. The area that is studied is the counties around Mälardalen during the period 2005 to 2009.The method chosen to achieve the objective is the hedonic price model. The variables are chosen after a preliminary study where a literature search has been made and a number of interviews with people in the industry.

Hur påverkar gummigolv i grisningsboxen suggans liggtider, liggbeteende och hennes tid för att lägga sig?

In the farrowing pens the amount of bedding material and the quality of the concrete floor has a huge impact on both the sow and the piglets. In this study imbedding of rubber flooring on the solid area in the farrowing pen was used to see if it had any effects on the sows lying behaviour when compared to concrete. Another important aspect was to evaluate if the rubber floorings had a high enough durability to resist the normal wear in a farrowing pen. Concrete flooring is assumed to have a higher thermally conductive effect then rubber which can affect the sow?s chance to cool down.

Modeller för brösthöjdsålder för tall och gran :

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the trees on basis of the number of annual rings at stump.

Methods for Locating Distinct Features in Fingerprint Images

With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.

Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder

This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.

I Idolvinstens konfetti och kamerablixtrar: Idol-Agnes vs Idol-Markus: en kritisk diskursanalys av hur en kvinnlig respektive manlig vinnare representeras i bevakningen av Idol 2005 och 2006

Avsikten med den här uppsatsen har varit att undersöka hur könsstereotyper skapas genom att titta på hur kvällstidningarna konstruerar och reproducerar kön/genus när de representerar en kvinnlig respektive manlig Idol-vinnare och vilken betydelse det kan få för meningsskapande processer. Jag har tittat på två kvällstidningars artiklar dagen efter vinsten för Idol-Agnes 2005 och Idol-Markus 2006 och gjort en kritisk diskursanalys på artiklar, bilder och Idol-postrar för att undersöka vilka bakomliggande diskurser som blir synliga i hur tidningarna väljer att representera en kvinnlig respektive manlig vinnare. Till min hjälp har jag haft Judith Butlers teori om genus som en performativ akt och den heterosexuella matrisen, Stuart Halls tankar om representation och stereotyper, och van Zoonens feministiska mediestudier och tankar kring manliga och kvinnliga blickar. För att förklara vilka rutiner och normer som styr en medieproduktion av en text har jag använt mig utav Atheide och Snow´s medielogikbegrepp. Jag har gjort en kvalitativ analys utifrån Norman Faircloughs kritiska diskursanalys för att komma samhällets diskurser på spåren.

Förbättrad omvårdnad med sårprodukt av mjölksyrabakterier och honung, för hästar med muggliknande sår

Wound care of the horse?s distal part of the leg is challenging. Due to that distal limb wounds are easily enlarged, infected and generally heal slower than wounds on the body of the horse, the need for improved wound nursing arise. One way of improving wound nursing is to evaluate new ways of healing treatment. In this study, evaluation was made of a new product consisting of lactic acid bacteria and honey.
