Crop efficiency in utilizing available nutrients is an important factor in increasing produc-tivity and reducing the environmental impact of agriculture. Nitrogen is the nutrient that plants need in the largest quantity and wheat, along with maize and rice, is the world's most cultivated crop. In this work, the Nitrogen Use Efficiency, NUE, during the major growth period, HTP, of twelve different spring wheat varieties, were examined. The NUE was calculated as the product of uptake efficiency of nitrogen, UN, and the conversion effi-ciency of nitrogen to biomass, EN. The purpose of this work was to find if there are varietal differences in NUE and its components among the twelve varieties and to link a high NUE to specific characteristics of the varieties.

Starch is a naturally occurring substance in most plants and is used as energy storage. It is a component that mainly consists of amylose and amylopectin. Together they build a complex pattern which gives starch its specific properties. The proportion of amylose and amylopectin varies in different plants but generally starch consists of 25 % amylose and 75 % amylopectin. There have been discoveries of barley varieties containing 100 % amylopectin called ?waxy starches? or ?waxy barley? as well as varieties that have a high content of amylose, around 70 % and these are called ?amylotypes?.

Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.

AbstractTitle: To work or not to work, an essay about information and inspiration on www.ams.se.Number of pages: 39Author: Ann HöglundTutor: Peder Hård af SegerstadCourse: Media and communication Studies DPeriod: Fall 2005University: Uppsala University, Department of information science, Division of Media and CommunicationPurpose/Aim: To investigate the frequency of ethos, logos and pathos in the work-guides on www.ams.se, and study how they match the needs of the respondents in the essay-interviews.Method/Material: To investigate the needs and wishes for information I have made three group-interviews with university students. In order to analyse the texts and films on www.ams.se I have used tools from the modern rhetoric analysis. In the last part of my analysis I compared the results of the rhetoric analysis and the requests from the interviews to see if and how they match.Main Results: The respondents requested inspiration for their future work lives, and information that could de-dramatize the image of working. The texts on www.ams.seconsist mostly of facts, while the films made a slightly more emotional contribution to the image of the occupation. The films showing relaxed and satisfied people can be seen as a way to de-dramatize the image of working-life.

Title: ?Du kommer väl ihåg hur det var att gå i skolan?? ? En visuell retorikanalys av fem av Friends antimobbningsfilmerNumber of pages: 75Authors: Radhika Bhasin and Christoffer OrreTutor: Marinette Fogde and Gudrun WeinerCourse: Communication, Advanced CoursePeriod: Spring 2007University: Division of Media and Communication, Department of Humanistic Science, Örebro UniversityPurpose/Aim: The purpose with this essay is to examine in what ways the Swedish organisation Friends advertising films against bullying rhetorically and visual rhetorically intend to convince their audience of their message.Material/Method: We have been studying five of Friends advertising films against bullying. The five films were chosen because they all originated from the same campaign against bullying amongst schoolchildren. The methods used were partly rhetoric analysis and partly visual rhetoric analysis.Main results: The conclusion we can draw from this study is that Friends anti-bullying films uses several rhetoric methods, both classic and visual, to convince their audience. Occurrence of pathos (emotions) arguments as convincing method was most commonly used, followed by ethos (sender trust) and only a few logos (fact) arguments.

AbstractTitle: Dragshow on the seven seasNumber of pages: 51 (56 including enclosures)Author: Therése PlastrougiTutor: Ylva EkströmCourse: Media and Communication Studies CPeriod: Fall 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: My main purpose with this paper is 1) to study how film as a media can subvert traditional gender constructions and 2) study the character of Elizabeth Swann in the trilogy Pirates of the Caribbean through four dimensions; Gender performance, Class, Desire and Power.Material/Method: My main material is the trilogy Pirates of the Caribbean. I have studied Elizabeth?s character based on semiotic and narratological methods.Main results: Film as a media possesses the full potential to change traditional gender roles, but the full subversion is denied due to the heterosexual matrix. Elizabeth?s character almost completes her subversive journey throughout the trilogy, but since she too is a victim of the heterosexual matrix, a full subversion is not possible.Key words: gender performance, class, desire, power, sex/gender, subversion, narratologic, semiotic, queer, feminism, pirates of the caribbean, intersectionality, parody.

Title: Share anything Swedish ? a study of CommunityOfSweden.com (Share anything Swedish ? en studie av CommunityOfSweden.com).Number of pages: 57 (64 including attachments).Author: Daniela Brandel.Tutor: Else Nygren.Course: Media and Communication Studies C.Period: Fall 2008.University: Division of Media and Communication, Department of Information Science, Uppsala University.Purposes/Aims: To learn what happens when the public-private tourism organisation VisitSweden starts an online community, where anyone is free to post stories and photos about a Swedish experience, and to understand how a participatory culture can help an organisation develop relevant material and thereby reach a wider audience.Material/Method: The study is an analysis of VisitSweden's community CommunityOfSweden, its structures as well as VisitSweden's use of the information posted by the readers on the community. Hence the material consists mainly of content from the community www.communityofsweden.com and the webpage www.visitsweden.com. In addition, the study is also based on an interview with VisitSwedens communitydriver Tommy Sollén.Main results: Members of CommunityOfSweden help VisitSweden to promote Sweden. This is possible because the community posting format and the participatory culture within the community are well designed and planned by VisitSweden, even though the organisation was not completely sure about the outcome.

The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.

The underlying purpose of this study is to see whether a library focused solely on providing literature in other languages than Swedish serves as a unifying, integrating force, or as an agent for division and exclusion. The study focuses on the International Library in Stockholm. The authors have created a profile of the visitors of the selected library, concerning their characteristics, their library habits and their perceptions of the International library. This profile has then been compared with the staff?s perception of the visitors as a group.

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

Over the years, what people have considered as the center of Stockholm City has gone from the medieval Stortorget in Old Town to the contemporary Sergels Torg. But more recently it has become unclear how the area really works. It is difficult to say where the actual central part of Stockholm lies, because while the Central Station is where the majority of people arrive into town, it is not necessarily close to Sergelstorg (considered the center of town) or other attractive commercial areas. There's also another issue with where the center of Stockholm is located. The railways and roads running along Klarabergs Viaduct acts as a divide between the areas of Kungsholmen and Norrmalm; these rails, roads and water separate the two areas from each other. In response to this problem of area division, a plan is being made to construct a new district near the center to mend the gap between the districts. The idea is that the center of Stockholm city will become more lively and attractive. The plan includes building new housing, commercial areas and a larger terrace called Mälarterrassen. In addition, improved mobility within the area is being planned by having better public transportation lines like City banan and tram named Spårväg City construction, as well as more pedestrian areas shall make the area become a district to thrive in.How the area will actually operate in the future is still unclear and many questions still exist about how the area will be able to compete and, above all, integrate with the other districts. The parts considered to be most important for the area is the scale of residential property and an attractive area that keeps people in the area and to encourages them to pass through the area. Perhaps the best solution would be to have something special planned in this area that can attract people in the community ? a city park, for example?.

West Pokot County is located in North Western part of Kenya where the previous lifestyle was nomadic pastoralism. However, in recent years the semi-arid county has been under dramatic developments and a sedentary agro-pastoral lifestyle is now growing. This is a major change in production systems and there is a big knowledge gap especially for the livestock based agro-pastoral systems. The main objective of this study was to investigate the current situation of animal husbandry in West Pokot. Twenty farmers were interviewed in Chepareria Division, using semi-structured interviews to investigate if the use of enclosures have had any effect on animal husbandry in West Pokot and if so, how have this method affected the animal husbandry? The results of the study indicated that there is a difference in animal husbandry between farms using enclosures and farms not using enclosures.
