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.

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.

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.

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.

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.

Fusarium head blight is a large problem world wide which reduces the yields and the quality of small grains. Shrunken kernels with decreased thousand kernel weight as an effect and pro-duction of mycotoxins are some of the problems caused by infection of Fusarium spp. To avoid toxin contaminated bulks to enter the food and feed chain it is important to have tools for prediction and analysis of the fungi and toxins. Good prediction methods are also impor-tant in the breeding industry since early identification in trials of lines with high resistance or susceptibility simplify the work. To compare different techniques for these objectives this project was initiated.

AbstractTitel: Self-presentation at online dating ? through a gender perspective and an age perspective.Number of pages: 44Author: Karin WestlundTutor: Amelie HössjerCourse: Media and Communication Studies CPeriod: Autumn term 2009-12-21University: Division of Media and Communications, Informatics and Media, Uppsala UniversityPurpose/Aim: The aim of this essay is to examine the phenomenon Internet dating through a gender perspective and to some extent through an age perspective. What do the members? presentations look like? Do men and women select different ways to present themselves, and how does it look between the different age groups?Material/Method: Qualitative method with 42 presentation texts, half men, and half women in three different age groups collected from a Swedish dating site.Main results: The study shows that men and women choose to highlight their good points at self presentation in the student forum. The differences between the various age groups proved not to be significantly large.

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.

Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.

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.

Background: Infection with Human Papillomavirus, HPV, is one of the world's most common sexual transmitted infections. The virus causes genital warts (condyloma) but certain virus types can cause cancer. The most common cancer type caused by the virus is cancer of the cervix. Nowadays there is a screening program for women between 23 and 60 years of age where Pap smears of the cervix is taken to discover abnormalities at an early stage. Cervical cancer is very common all over the world and this screening program saves many lives, but not in the less developed countries since the screening program is too expensive.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

In my work I have received a lot of concrete advice about improving the cooperation between landscape architects and contractors. Here is a list of suggestions from both cathegories: Landscape architect's advice: ? Be humble, show respect. ? A practical approach makes cooperation easier. ? Call together a startup meeting with all the consultants and builders. ? Establish a network of contacts with serious contractors whom you can recommend to customers. ? Don't hesitate to ask the contractor for advice; they often have lots of useful knowledge. ? It is important to have clearly written and thoroughly worked out documentation. ? Never let a newly graduated landscape architect visit the buiding site without the company of an experienced colleague.

The background to this final thesis is that our mandator, A-hus, was interested to examine which roof system that would be most appropriate to their types of houses. To investigate this, we first conducted an evaluation of the most commonly used roof systems in Sweden today: decking, board, roof cloth and prefabricated roof cassettes.To gather information about the different systems we have conducted interviews with several professionals within the construction industry, done an extensive literature study, and gathered information from the Internet.Based on the evaluation of roof systems and the literature, we analyzed advantages and disadvantages of the roof systems from three main perspectives: system characteristics, economics and other characteristics. We found these perspectives to be the most relevant when selecting a roof system.The main perspectives comprise three categories which are graded. These grades are then added together for a score for each main perspective and a total score for the three main perspectives. Then we compared the systems and, based on the scores, suggested one roof system as the most suitable for A-hus.Our result suggests that the prefabricated roof cassettes probably is the best solution for A-hus, but only if it is possible to standardize the cassettes and still maintain the flexibility to match A-hus? house types.
