Solceller ? Solen är ju gratis! : En undersökning av huruvida solceller är ett fördelaktigt energisystem med avseende på tekniska och ekonomiska aspekter
This report is a result of a bachelor thesis at the school of Architecture and the Built environment (corresponding to 15 HP) and is written during spring 2012 at the Royal Institute of Technology (KTH) in Stockholm. The Bachelor's essay is based on the design and dimensioning of a house which is located at a predetermined site in Malmo, Sweden.The idea is to construct a house that is appropriate to use for an average Swedish family of four family members. The house is designed in a modern way with respect to ease of access and disabled facilities. The installation that have been considered are heating, ventilation, sanitation and electricity. Construction calculations and material selection are also discussed.Furthermore, a study about photovoltaic cells has been done.
Estimation of reindeer lichen biomass by image analysis
During consultation procedures between forest owners and the Sámi, data on, e.g., reindeer lichen biomass on the current site is needed. Hitherto, the existing methods of measuring lichen cover and biomass has been either objective methods such as the Point Intercept method, which is time consuming, or some sort of subjective visual estimation, which is faster but less accurate. However, both these methods are sensitive to different observers and/or to different inventories. This paper addresses the further development and evaluation of a photographical inventory method that uses colour distribution in images to estimate lichen biomass. During the autumn of 2011 six different locations, with different grazing pressure and lichen cover, in Norrbotten county were inventoried using both the Point Intercept method and the photographical method, complemented with collection of biomass samples.
Evaluation of a selective media for the detection of gram-positive bacteria in leg ulcers and pressure wounds
Hard-to-heal ulcers are resource intensive due to the fact that they are difficult to treat and especially vulnerable to bacterial invasion. The bacterial culture contaminating these wounds often consist of several different bacterial organisms that originate from endogenous sources. Necrotic material in ischemic ulcers provide nutrition which support bacterial reproduction, increasing the risk of infection. Determining causative pathogen in infected ulcers proves to be difficult when culturing swab samples, however Staphylococcus aureus and hemolytic streptococci generally act as primary pathogens. The aim of the study was to investigate if the detection rate increased for S. aureus and hemolytic streptococci when culturing swab samples from ulcers on Columbia CNA; a media selective for gram-positive bacteria.
Om man bygger dörren för liten kommer ingen in: En kvalitativ studie av tillgängligheten på folkbibliotekens webbplatser
The Internet has played an important role for libraries giving them a means of fulfilling their democratic mission of giving equal access to everyone, including people with disabilities. In order to achieve this it is of the utmost importance that they ensure that their web sites are accessible. In this masters thesis we have examined to what extent the web sites are accessible. The thesis is based on theories of human-computer interaction, information architecture, pedagogy and a checklist. The checklist is derived from established international guidelines from W3C, which has been adapted to, and is used by Swedish public authorities to achieve the mission of a ?24-hour authority?.
En utvärdering av Peabs inköps- och avropssystem
This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.
DU#kulturskolan : En kvantitativ studie om hur elever ser på sitt engagemang då de musicerar och undervisas på kulturskolan.
The Sand Catcher The thesis project The Sand Catcher investigates the encounter between permanent structures and an ever-changing landscape. The migrating sand dune Råbjerg Mile in northern Denmark is 40 meters high and moves more than 15 meters every year. By introducing a solid structure on the site, the fast movement of the sand dune is emphasised and thereby our view of time and space.Through intuitively building models with varied openings and densities I investigated how architectural elements react with sand. From these experiments a series of spatial features and effects were found, generated from the meeting with the sand.The Sand Catcher is a solid and permanent structure. The sand is the liquid element that generates new spaces, circulations and experiences.
Multitorget :
This is a final project which makes up 20 credits at the Landscapearchitecture programme at SLU in Alnarp. The thesis is design based.
My final project is comprised two parts; of a competition entry for ? A New Square in the Centre of Täby? as well as a theoretical study that derives from the competition proposal. The competiton itself was announced on March 1st 2007 with the final hand-in date on May 28th 2007.
The program of the competition asked for a flexible urban square that offers a diverse range of activities that can be used during both night and day, all year around. I became interested in the term ?mutlifunctionality? and I went on to use the subject as a base for my design approach.
Arkitekturtävlingar och platsbesök : the core project competition
Competing is a well established work model among Swedisharchitects as well as in the international architect work force.Through this study we set out to get better acquainted with thiswork model in theory and in practice, and to hopefully gainknowledge that will be of use to us and to others working in thefield of architecture.Techniques, materials as well as the artistic expression ofcontemporary architecture is international and today?s architectsoperate on a global labour market. Architects often commit to workon assignments far away from where they are based. Therefore,to physically visit the site of interest may be time consuming,expensive as well as harmful to the environment. Is it possible fora designer to accomplish relevant proposals on how to develop andimprove a place that he or she has never visited? May there evenbe situations in which the outsiders point of view is preferable?These are questions that we aim to investigate, and we do sothrough participation in an international design competition.
Vägar och markanspråk inom vindkraftsparker i Västerbottens län : Hur verkliga mått förhåller sig till vad som uppges i miljökonsekvensbeskrivningar
The purpose of this study was to increase the level of knowledge in the field of Environmental Impact Assessment (EIA) for wind power. The study includes six wind power farms in the County of Västerbotten in northern Sweden. The main questions were: What are the real dimensions of roadways and land claims for both roads and wind power turbines? How do those dimensions correlate with the dimensions stated in the EIA? Are there any differences in values of the dimensions between the wind power farms that are included in this study? The width of the roadways and the land claims for both roads and wind turbines in wind power farms were examined on site. The results from the examinations were compared with the dimensions available in the EIA for each wind power farm.
Brucellosis in small ruminants : a seroprevalence study in peri-urban farming around the region of Dushanbe, Tajikistan
The mountainous Central Asian and former Soviet country Tajikistan is the least advantaged country economically among the former Soviet Union states. Approximately 6.5 % of the land is arable in a country where roughly 80 % of the households typically own small numbers of sheep and goats. Management practices and animal husbandry in the villages such as uncontrolled breeding, mixing of animals on pastures favor transmission of infectious diseases.
Brucellosis is a zoonotic bacterial disease caused by Brucella spp. The disease is endemic in Tajikistan. B.

Species diversity and geographical distribution of Fusarium species on winter wheat in two regions in Sweden
Various Fusarium species causes some of the most common cereal diseases worldwide. Besides the yield losses that can be a result of these diseases, strains from several Fusarium species can produce mycotoxins, some very toxic. The aim of this study was to investigate which Fusarium species and how many that occurred in winter wheat grains from Mälardalen and Kalmar län, if there was any difference in the distribution of Fusarium fungi between the regions and the potential within species to produce mycotoxins belonging to the group trichothecenes. Winter wheat grains collected in 2009 from ten fields (unsprayed plots) in the two regions were analysed for Fusarium species. PCR was used to amplify the TEF region where after the samples were sequenced.
Identifiering av saneringmetoder med översiktlig bakgrunds- information - En studie av förorenad industrimark på fastigheten Elektro 6 i Gullspång kommun
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Hur skapar man en funktionell och beständig dörrmiljö? : En närmare studie av ståldörrar
Today?s construction buildings contain more advanced technologies than before. The development of newer and stricter regulations to the construction industry makes the door environment more and more complex.In large construction projects the door environment is held up as a major challenge to get to in a good way. It turned out after a discussion with one project manager and a site manager at NCC, that the door environment is difficult to get right in major construction projects and it often causes many error reports in to the aftermarket after that the final inspection is completed.Interviews have been done with key figures in the building process at NCC and Akademiska hus. A study on a university building for around 3500 students and with 300 workplaces was made.
