The objective of this thesis is to explore opportunities to enhance the phosphorus use efficiencyof inorganic fertilizers in crop production, with techniques available today and in thefuture. Phosphorus is a finite resource of declining quality; therefore a phosphorus use efficiencyin crop production of only 15-30 % is unacceptable. The main reason for low efficiencyis the retention by Ca and Mg in calcareous soils and Fe and Al in non-calcareoussoils. Due to the low mobility of phosphorus, plant uptake is mainly dependent on root growthrather than diffusion. Therefore, measurements need to be taken that benefit contact betweenroot and fertilizer, before fertilizer phosphorus becomes unavailable to the plant.

This thesis considers the development of the software for an, newly developed, embedded real-time control system, based on a Periferal Interface Controller (PIC). The control system is developed to be used for several different applications. In this thesis work, software for two different applications are developed. The first task is a time controlled system, while the other task is implementation of aPI-/PID-controller. A user interface is also developed and implemented.The time controlled system is an automatic horse feeder, which is used for feeding horses at certain predefined points in time.

This thesis has been made in cooperation with the forestry machinery producerEco-Log in Söderhamn. The focus of the thesis has been to find a cheaper wayto open the large engine hood of the company?s harvesters. The goal was tofind a solution that could increase the value for the customers by being saferand simpler to use, or, at the least, keep these values at an equal level comparedto the previous solution.In order to make it possible to CE-mark the new solution, it was importantMachinery Directive that came into effect from the beginning of 2010.To begin with, a specification of requirements was set up. Thereafter, anumber of different basic concepts was retrieved and evaluated.

Although textbooks are scientifically proven that they are important and central to the school curriculum one should think critically about the content in textbooks - is it really compatible with the curriculum of following the textbook tradition? As a teacher there are different ways to reflect on which textbook to choose. It is important to compare several textbooks with each other and be aware that a textbook should follow the curriculum. A teacher examines many sections/topics in the textbooks, but in this paper only one section will be reviewed among four different textbooks. The section to be compared, in the paper, is the interwar period.

This thesis is a study of humidity at Knauf Danogips external plasterboard. The study is performed at the building project Kv. Maskinen in Jönköping in cooperation with NCC Construction AB and Knauf Danogips. The measuring was performed during five winter/spring months to see how the weather influenced the plasterboard.The measuring was performed at a small two-storied building and a larger fourstoried building. From the buildings` placement were a couple of measuring dots selected and to get a good result was the dots located in the four cardinal points.

Essay in Political Science, C-level, by Camila Alvarez Cea, spring semester 2010. Tutor: Alf Sundin?Reality or a Political Mirage? ? A Study of the Swedish Press Views on the Health Insurance Reform in the USA? The purpose of this essay is partly to examine whether the picture that Swedish press presents of the health insurance reform in the US, which is part of the Patient Protection and Affordable Act bill, will be of crucial importance to the possibilities that the American population has to receive health insurance. The main research question is accordingly: ?Does the picture that Swedish press presents of the health insurance reform in the USA, seem like something that will be of radical importance to the possibilities of the population to receive healthcare?? The purpose is also to examine in which model (demand or market) the opinions of the Swedish press fits. This purpose will be answered by using three specific questions asking whether their opinions differ when it comes to three criterions: organization, financing/resources and delivery systems.

This thesis was performed at Scania?s purchasing department of non-automotive products inSödertälje, Sweden during spring 2007. The management of the purchasing department ofnon-automotive products believe that their internal customers might not have fullunderstanding of what the purchasing department does. This is a problem because the internalcustomers might not use the contracts negotiated by the purchasing department or they mightnot involve the purchasing department when making purchases.The purpose of this thesis is to examine if and how the internal customers? perception deviatesfrom the purchasing department?s perception regarding the task of the purchasing department.And also to create a communication package with the purpose of increasing the internalcustomers understanding of what the purchasing department does.

This paper analyzes the content of eight Islamic Friday-sermons, held at Chalmers Technical University in Gothenburg in spring 2010, organized by Chalmers Islamiska Förening (CIF) (Chalmers Islamic community).The forces of globalization, the accessibility of information and the Internet have given rise to discourses and movements that know no national boundaries. The accessibility of these global movements and discourses through media, Internet, etc., affect the way Muslims in Sweden interpret and practice their religion. Thus, this paper includes discussions and descriptions of global Islamic revivalist-movements, and relates the contents of the sermons at Chalmers to these movements. In the sermons, the imams often discuss the concept of a global Muslim community, the umma, and their perceptions of the prescribed ethics linked to this community. They often relate this discussion of ethics to frequently discussed issues in the West such as equality, justice and ethical standards in war.

Internet's entry into our home has changed our communication capabilities. As a result more and more services in the digital world are available. Besides e.g. shopping, gaming and general information, different social networks now offer preventive and therapeutic health-oriented services. When being asked by several young people, with whom I have been working in a clinical setting, to offer conversations over the Internet that enables both to see and to hear each other in real time, I decided to conduct a pilot study which is presented in this paper. The aim was to investigate the feasibility of offering supportive therapy using video calls over the Internet.

I have for my one year master's thesis worked on arranging and cataloging the archives from the missions stations of Musana, Congo-Brazzaville and Sundi-Lutete, Congo-Kinshasa, belonging to the Swedish Missions Church (Svenska Missionskyrkan). The archives contained records written in Swedish, French and Kikongo, from primarily the years 1910 until 1961. Records have though been found that adhere from both prior to and after these years. These archives are deposited at the Swedish National Archive and it was therefore important to take the opinions and regulations of both parties into consideration, as well as relying onto archival theory.The archives were initially scattered and had in some parts been organized by an archivist without formal schooling. The major difficulties in this work has therefore been to establish the provenance ? to which creator the documents belonged to, and also to decide to which degree the principle of the original order should play a part.

This report is our Master thesis. Our work has taken place at a one-stop-shop in Sölvesborg during the spring of 2002. We have conducted ethnographical studies concerning the one-stop-shops frontdesk and telephone exchange. During these studies we became aware of some differences under which the daily work was to be carried out. When operating the switchboard the staff usually work alone and perform the tasks individually.

I want to look at the possibilities to start selling hot water from a small district heating plant with bioenergy. My reason for doing this project is to look at a new business opportunity for our farm. Our company have less work during the winter time compared to the spring and this project will give us more work during the winter. I also want to take as much material as possible for heating from our farm in order to increase the value of the products from the farm. The project is in a village near us, where we should support a school, a churh, a home for the aged, a kindergarten and a parish hall with heat. In my work I have compared two different alternatives with each other. The first alternative is to put a central heater in one of the buildings, the home for the aged, in which we will burn oat.

This report deals with an exam report written by Olle Hjalmarsson and Thomas Likar, students at Högskolan i Halmstad. The project was carried out for Haldex Traction AB in Landskrona whose business consist of manufacturing automatic all wheel drive systems (AWD-system). These systems consist of a plate clutch which activates all four wheels of a 4-wheel driven vehicle. An important component in these clutches is the accumulator which basically consists of a piston under the load of a spring which creates an oil pressure with the help of an electric motor used for actuating the clutch.At Haldex difficulties has been experienced regarding the assembly of the accumulator parts due to the small tolerances between the piston and the hole of the accumulator in the cast aluminium housing. Attempts have been made to assemble the parts in existing robot cells.
