The aim with this thesis is to investigate two different methods used to test usability on web-sites to determine the advantages and disadvantages of two methods and compare the results. The two selected methods are the think aloud method and asynchronous remote method. Re-mote usability testing has existed for more than ten years but the possibilities with this meth-od needs to be explored more.To achieve the purpose of this thesis a case study was conducted on an e-commerce site and for the online remote usability testing software was used.The results of this study show that think aloud usability testing encounter more issues with the website than the remote usability testing..

Almost for as long as there has been breeding on bovine species, there has been a wish to have a higher proportion of offspring of either one or the other gender. In dairy cattle, heifers are more valuable, while in beef stock bulls are preferred. Semen is sorted based on the difference in DNA content between the X- and Y-chromosome in the genome of the sperm. X-chromosomes contain on average between 3,70 to 4,22% more genetic material than the Y-chromosome. Commercially it is the method of flow cytometry that is being used, which is always under improvement.

The Pitted ware dwelling site Ajvide on the west coast of Gotland in the Baltic Sea is, because of its long continuity from the late Mesolithic to the middle of the Scandinavian Bronze Age, an interesting research object concerning Stone Age in the Baltic area. In this essay, a comparison between two activity areas on Ajvide have been carried out in the purpose of finding out what these areas may have been used for during the middle Neolithic.  It has been showed, through zooarchaeological analyses of animal bones, that the areas most likely are depositing sites for slaughters refuse and food debris. If it is a result of everyday or more ceremonial activities is left undetermined..

Complex Vertebral Malformation (CVM) is an autosomal recessive inherited defect in the Holstein breed. The defect has lead to structurally malformed calves and losses of pregnancies. To determine the effect of CVM on fertility in the Swedish Holstein Breed 375 Holstein bulls used in breeding by Svensk Avel and Skånesemin were assigned to this study. 228 bulls matched the criteria of birth year, 1995-1999, > 75 inseminations and a known CVM-status. Of the total 228 bulls 53 of them were CVM-carriers and 175 were non-carriers. The SAS-programme was used to determine the effects of CVM-status, the bull?s father and birth year on Non-return rates (NRR) for 28, 56 and 168 days.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

The writing style of a particular author can be divided into many subfeatures, for example use of words, language and syntax. Focusing on the latter, this study aims to show how well syntactic information alone can attribute the correct author to a document. Syntactic information is defined as overlapping syntactic subtrees of height one (1) for all sentences of all included documents. The performance is compared to that of the previously very successful method of comparing stop word frequencies. These are words normally excluded from search engine queries, because they are present in all sorts of texts regardless of topic.

In this paper I will attempt to recreate a prehistoric landscape surrounding the rock carving site of Släbro at Nyköping in Södermanlands län by using GIS. The main focus area is the river valley at Släbro and the six panels with rock carvings that have been dated to the Bronze Age. I?ll attempt to shed light on a long lost landscape. The shore line displacement have been extensive in this area a reconstruction will visualize the relationship between the panels, and their relationship to the surrounding landscape.

Population growth leads to an increased need for new buildings, both residential and commercial. The regulations of structural design also changes with time. From a sustainable community perspective it may be profitable if existing buildings, that no longer performs their original function, are reconditioned. Knowledge and understanding of the surroundings of the residence must be available. Regulations regarding accessibility to all has increased.

Fresh Kills park and the The High line park in New York, Downsview park outside Toronto the birch landscape at Shiphol Airport have something more in common than being big new park landscapes.They all include thoughts and images about ecology. These images are neither typically nature picturesque nor typically garden stylish. In Sweden we have the biotopes of Ankarparken, the new design of Kristinebergsparken. At Chelsea Flower Show in England Swedish nature put in a garden format is winning awards. There are some new ecological influence in the air.

This report presents the preliminary study and work for the development of a site structure for the upcoming reengineering of inter-tool Infopunkt. The report describes how I have conducted a study regarding the current inter-tool information center and its development potential. Thereafter compiling the information to develop a comprehensive design approach to create a sitemap. The sitemap illustrates a new updated page structure for Infopunkt and was the primary goal of the thesis. The sitemap I have developed will form the basis for the agency that will later on develop the new updated version of Infopunkt..

In this thesis we propose a conceptual plan for thedevelopment of an Agroforestry Training Centre (ATC)in Musoma, Tanzania. The aim is to make a proposalto support peasant education in agroforestry. How canan ATC in Musoma be developed into a stimulatingand educational park suitable for teaching agroforestrymethods to peasant farmers and other potential users?To answer that a field study was conducted to investigatehow our client Vi Agroforestry Programme (Vi) and thetarget groups of the client can benefit from the site.The thesis begins with a short explanation of thecontext, in which the ATC plays a part followed by amethodology chapter. Next are three chapters presentedwhich introduce the reader to the research conductedbefore starting the proposal, these include: results ofliterature studies, study of precedents, and results of fieldstudy.

People have utilised and influenced the boreal forest for many centuries. Prior to the industrial revolution during the 19th century, however, human use primarily only had a low impact on the forest. When the timberfrontier swept over the country, the Swedish forests came to change for ever. The study site for this thesis is situated in the northern part of the county of Västerbotten, Sweden, and has previously been a National forest. Today the area is an ecopark and the land is owned by the forest company Sveaskog.

The aim of this study was to examine what impact restored and constructed pounds and wetlands have on waterfowls in the area of Linköping. The birdlife in five constructed wetlands werechosen to investigate if specific factors like age, size and vegetation affected the avian diversity in wetlands. Also, extra focus has been given to the threatened Horned Grebe (Podiceps Auritus), breeding in the studied area. The results showed that the number of species as well as individuals of waterfowl and Horned Grebe changed over time in what might be a result of succession in the wetlands. Comparing the number of birds to the size of the wetlands showed a clear correlation. Larger areas inhabited greater numbers of species and individuals.

The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.

The quality of a design can improve essentially through a participatory designprocess. Initially, The Mulberry School project was supposed to be finished in two months but the involvement of artist Scott G Burnham extended the work and brought a new dimension into the project. In the beginning, Scott and I both worked on the project unaware of each other. I was appointed by the architect to design the external areas of the school and based on a site survey and analysis of the factors infl uencing the site I created a design proposal with the concept form and function. At the same time Scott performed a series of workshops initiated by the school. The purpose and goal was to include the students in the redevelopment of the school and to produce a design based on the thoughts and wishes of the students.
