Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Makrocykliska laktoner har varit flitigt använda avmaskningsmedel hos olika djurslag sedan mitten av 1980-talet och används fortfarande. För att avmaskningsmedel ska vara så effektiva som möjligt är det viktigt att veta hur de tas upp och omsätts i kroppen hos olika djurarter. Detta för att kunna anpassa doseringen till olika djurslag. Några farmakokinetiska parametrar har undersökts för att se om det förekommer skillnader i upptag, distribution, metabolism och utsöndring mellan nötkreatur, får och gris. Genom att jämföra olika studier fann jag skillnader i halveringstid, AUC, Cmax och tmax mellan gris, nötkreatur och får.

Man's life has changed in many ways since technology made it?s entry for public at large. In response to this change the science of human-machine interaction was invented. It has in turn evolved into human-computer interaction. With this science the focus is on the customization of the system for the actual person who will use it.The thesis has been implemented in a telecom company's development department.

Swedish healthcare systems have endured harsh criticism from healthcare professionals because of their inability to understand healthcare processes. These systems have been identified as significant time consumers, and Swedish healthcare is therefore facing a major challenge to assure patient safety. The following paper is based on a workplace study, which aims to examine healthcare systems? impact on physicians? practices. Our findings show that physicians spend substantial amounts of time chasing information, rather than managing information and pursuing healthcare.

The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking. Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.

The purpose of this development project is to create a model for working with a high school project in Electrical and Energy Program. It should be conducted in a form like companies do according to the goals from The Swedish National Agency for Education. In order to fully perform this we use the concept of Young Entrepreneurship. The model is created according to the new conditions from The National Electrical Safety Board. There is now an exception saying that a student during education is released from the demand of employment that is the normal procedure where you are under supervision from a certified electrician. During the project there has been theoretical and practical examinations in order to clear out the advantages and disadvantages using this model, but also to examine whether it is useful in the future and to what extent it can be used. The result indicates that the model is useful and fulfills the goals from The Swedish National Agency for Education but that the model has its limitations and difficulties.

The Work has been performed to, and in cooperation with Vetlanda Energi och teknik AB.District heating for commercial purpose started in the USA in 1877. Today the network has grown into big and complex systems, which demand maintenance and service to keep up the security of the delivery. When a district heating network expand, it becomes difficult to perform reliable calculations. For this purposes there are a few suppliers who design and deliver systems for documentation and calculation of district heating networks.Vetlanda Energi och Teknik AB is in the position where they must get a system for documentation and calculation for district heating, and therefore they need a basis to get a system. The target is to write a requirement specification that will follow the basis.The Swedish market has been inventoried, and suitable systems have been selected.

To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.

The Swedish building and property management sector are responsible for about 30 % of the total energy use. In order to take environmental consideration, different environmental assessment tools and standards are used. Miljo?byggnad, Svanen, FEBY12 and PHI are some of these. There has been increased interest to certify buildings and therefore it is of interest to evaluate the assessment of the energy field to see if relevant energy aspects are assessed.

The purpose with this study is to compare different systems of grain storage from a financial point of view. Grain that is supposed to be fed to laying hens. The systems that were compared were different airtight storage of grain and a system of conventional storage. To make this case study I choose to compare four different systems. In the case study there was one system with bin drying of the grain, two systems with airtight storage of the grain and one system where you buy dried grain during the season. I made several of capital investment appraisal where I found the cost of each system, then I took the cost and divided it with the total grain use and calculated the cost for each kilogram of grain, and also the cost of the feed. Then I compared the cost from my case study with the cost of buying feed. All the systems except for one, gave a lower cost for the hen feed than buying feed from a dealer The best system, witch were bin drying lower the cost with about 80 000:- SEK.

Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.

An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.

Problemformulering: Små företag kan ha svårt att slå sig in på en marknad på grund av en begränsad marknadsföringsbudget och konkurrens från andra aktörer. Dessa företag måste därför i många fall använda andra mindre kostsamma metoder än traditionell marknadsföring för att etablera sig på en marknad.Syfte: Att undersöka hur ett mindre företag kan etablera sig på en marknad genom användandet av andra marknadsföringsstrategier än traditionell reklam. För att besvara vårt syfte två delar ur 4 P undersökts, plats och påverkan (distribution och marknadskommunikation).Metod: En fallstudie har gjorts av företaget Gooh där fyra personer på Gooh har intervjuats genom semi-strukturerade intervjuer.Analys: Gooh har gått från en exklusiv distribution till en mer intensiv distribution för att nå ut till fler kunder och konsumenter. I sin marknadskommunikation har Gooh använt sig av olika aktiviteter som viral och buzz marketing för att generera word-of- mouth både bland konsumenter och kunder.Resultat: Gooh har ökat omfattningen av distributionen samtidigt som de ökat omfattningen av marknadskommunikationen för att nå ut till fler kunder och konsumenter och etablera sig på marknaden för färdigmat.Slutsats: Gooh har använt sig av en kombination av distribution och marknadskommunikation i sin marknadsföring och genom detta fått ett stort antal kunder och konsumenter och därmed etablerat sig på marknaden genom icke- traditionell marknadsföring..
