Koncept - detalj - byggnad
Concept - detail - buildingStockholm International Fairs, new main entrance I studied at the KTH School of Architecture from 1995 to 2000. After completing my studies I wanted to work in an office that had a structural way of thinking and that knew the building process; I therefore chose to work for Rosenberg Architects. I have worked on a number of projects, among them several for the Stockholm International Fairs, from the Rica Talk Hotel and Hall AE, to the new main entrance.In the projects we undertook at the School of Architecture we had to identify and draw details that were central to our concepts. I have here identified some key details that we considered to be essential for the concept in a built project; the new main entrance of the Stockholm International Fairs completed in 2013. The entrance has complex logistics with multiple intersecting flows: exhibitors, employees, journalists, VIPs and others.
Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff
In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.
Storjuktan ? Rekonstruktion av ett sekels kvicksilverbelastning. : En undersökning av kvicksilverkoncentrationer i daterat bottensediment.
The aim of this study was to examine the current and historic mercury(Hg) load of the lake Storjuktan due to its recent exposure to a local potential source of Hg in form of the Sulphide mine Blaikengruvan(2006) and an earlier potential sources of Hg-load, the damming of the lake(1960s). Sediments were extracted using a HTH-sampler, freeze-dried, and analyzed for tot-Hg, LOI and activity of 210Pb and compared to samples extracted prior to the opening of the mine(2006). Constant initial concentration (CIC)-dating model was used for dating the samples. Low levels of Hg (100ng/g) were found throughout the lakes sediment. The highest levels of Hg(220ng/g) was detected at a depth of 4-5cm dating back to the mid 1970:s, suggesting that increased levels of atmospheric Hg rather than damming of the lake has caused the increase of Hg.
Spelutveckling och lansering av applikation till Android
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.
Studie i exteriör belysning : med tillämpning på Bokenäs, Volvos fritids- och konferensby
When creating a good lighting design it is crucial to know how different types of lamps work. Knowing what kind of light they emit and in which situations they work well is also very important.
In this master thesis I present different types of lamps and give an account of how light is spread through the different shapes of luminaires, reflectors, filters and so on. I write about how our eyes register radiation and connections between lighting and how it makes us experience space. Furthermore I deal with the effect of artificial light on living organisms and the environment.
After the theoretical studies I deal with the places I have visited to study how different lamps and luminaires work and look like in existing lighting designs. These visits have also been inspirational to my lighting proposal for Bokenäs.
Bokenäs is Volvo?s resort and conference center which is situated on the Swedish west coast.
Kontorshotell Jonsereds fabriker - Fastighetsutveckling av gammal verkstadslokal
This report presents suggestions and recommendations on how to convert an old industrial building, built in 1958, to an office hotel. One of the main criteria was that the floor plan should be flexible. The building is situated at Jonsereds Fabriker and the study was conducted for Hantverkslokaler i Göteborg AB, the estate owner.The survey is initiated with study visits at various office hotels, together with studies of literature regarding office planning. One conclusion from the study visits is that meeting-places, where the different companies can meet and exchange ideas and services, are important. Another one, and probably the most important parameter when planning offices is that they should have windows.
Energiaspekter på gestaltning : fallstudie Energihuset i Uppsala
This thesis has been carried out at the Department of Urban and Rural Development at SLU Ultuna during the spring semester 2009. The topic of the paper is how energy consumption can be influenced through design and if the conditions for good design decreases when solutions based on energy efficiency are used. The report is divided into one literature study and one part where energy efficient solutions are used in a design. The thesis work has its origin in a project called "Energihus i Uppsala." The planned building will be a center for energy research in Uppsala. The project aims to demonstrate to the public what is currently happening in research related to energy.
LANDALA Stadsdel i skuggan av det f?rg?ngna
In the post-war era many European countries were recovering from the ravages of the bombings of
the second world war destroying whole countries. Sweden being neutral was spared the destruction
of war but instead we demolished almost as much housing all by ourselves. A social program was
modeled to modernize the country and to drag the swedes out of poverty by building one million
apartments in just ten years and demolishing the old, dilapidated working-class neighborhoods. The
traumatic events of the demolition of large areas of both the central and the outskirts of most
Swedish cities is still very much present in the collective memory of people today and the new
modernistic districts are still paying the price of that, more than fifty years later. Today these
modernistic districts are in need of repair, and they are often homes to groups alienated from society
making their reputation even worse.

The embroidery is long and narrow with applications in the form of dragons and eagles on a ground of velvet cloth. The dragons and eagles are covered with metal threads.
Bostaden och de boende
AbstractWe all have experience of dwelling, which means that everyone can have an opinion about the architecture of the dwelling. Today the building companies do not have time enough to investigate which architecture qualities their clientele ask for in their apartments. JM AB use to call their apartments ?generous city apartments?. But do these apartments fulfill the needs of their dwellers? And what would the apartments look like if they were designed according to the wishes of the dwellers? When JM AB get knowledge about the dwellers needs and wishes they can make even better apartments for their future customers.The purpose and the objective with this report are to draw up proposals for tenant owner flat.
Validation of Steins/Arla Foods method for lactate fermenting clostridia in milk
One of the most serious and economically important defects caused by clostridia in milk products is the late blowing of semi-hard cheeses.Clostridia occur naturally in soil and can contaminate milk through crops contaminated by dung and soil followed by a less successful silage process, that give them opportunity to grow unaerobically. When anaerobic conditions occur, such as storage of semi-hard cheese, they ferment lactic acid to butyric acid and the gases CO2 and H2.At the fusion of Arla and MD Foods, a series of changes were conducted on the MPN method for lactic acid fermentation for clostridia in milk. These changes resulted in an increased accuracy due to an increased number of test tubes and the change of media from MRCM to BBB, Bryant & Burkey Broth, that was thought to be more selective for Cl. tyrobutyricum, the organism mostly found in hard cheese. When the number of dairy farmers that were given quality reduction fines increased, the new method was suspected and a validation was conducted.The validation included inoculation of different clostridia and bacillus strains into BBB substrate and enzymatic testing of positive samples with Rapid ID 32A.

Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.
