The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards to relevant system parameters. The purpose was to evaluate if the technology is a possible solution to reduce deforestation and support Malawi in climate change mitigation and adaptation. The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine which one was best suited to utilise as a digester substrate. After the installation, measurements of temperature, pH, biogas production, biogas composition and system functionality were made. The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.

This essay examines middle school students? understanding of a text read aloud to them in English and the connection between the degree of listening comprehension and the expected increase of vocabulary throughout middle school. The same listening comprehension test was carried out in grades 4, 5 and 6 in a middle school in order to survey differences in English listening comprehension in regard to the ability to reproduce the content of an oral text. The result shows that there was a progression from level to level when it comes to comprehension and the number of words reproduced and that this progression was most noticeable between grades 4 and 5..

This study was a final thesis, for the bachelor program in civil engineering at theUniversity of Uppsala, which was made on behalf of Riksbyggen in Uppsala. Acomparative study of two stain renovation methods; tradition pipe replacement andrelining was done with an environmental perspective. A simplified life cycleassessment (LCA) was done according to the International Organization ofStandardization (ISO) with the LCA tool Eco-indicator 99, in order to be estimate theimpact on the environment. LCA is a method that follows a product or a system?from the cradle to the grave?, which means that all the environmental impact over alifetime is considered.The work was executed by using a stairway with nine apartments in a house called?Uppsala Hus 9? as a reference object, which was provided by Riksbyggen.

AbstractMotor sports have been around as long as motor vehicles have been. Sports are often seen as costly polluter but in the same time the motor sports have encourages a large part of development, both for vehicles and other industries. Inventions like rear mirror and ABS brakes come from motor sports. One way to once again drive development forward while making motor sports carbon-neutral is to run the race cars on hydrogen. In this thesis, the goal is to convert a spark ignition engine for hydrogen operation.

The topic of this thesis interest is the relation between branding as a place making/marketing technology and the process of regionalization. The main proposition advocated is that the officially communicated image of the Øresund Region, as a cohesive place and community, is a space that has been configured with branding and can be described as a territorial simulation. The concept of territorial simulation consists of two conjoined terms: simulation which aim at explaining the idiosyncratic brand image, as a social formation, which does not represent the place it imitates but commoditise it; and territorial which seeks to visualize the process of the unfolding of this image as a territory. The main argument is made in the third chapter, which traces the process of actualization of the brand image as a territory: ?Øresund?.

Abstract In the contemporary world of information technology you find a multitude of applications and systems covering a broad spectrum of areas of need in different companies. One effect of this multitude of programs is the difficulty to make them exchange information with each other or to collaborate, since they are developed by different programming languages for different platforms, with different standards and different data formats. Our aim with this work is to describe how it is possible to tie these programs together to make them actually communicate with each other in order to exchange information, share their native methods and also to become a part of the overall business processes. In this integration task you will, among other things, find different levels of application integration such as data level, method level, application interface level and user interface level integration. Application integration also involves hardware components, called middleware, that facilitate the physical connection between applications. There is a range of different middleware products offered today on the market.

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..

The underlying aim of this paper is to find out how the management and employees in a grocery store on a relatively small community in Sweden is experiencing Technology-Based Self-Service (TBSS), and self-scanning. And how store management and employees experience that the self-scanning ability is received by their respective consumers. Several open individual interviews were conducted with the administrative head of sales and various employees working at different departments at Coop Forum in Skara In offering self-scanning, we believe that the store provides consumers with an opportunity to perform their daily purchases by an easy and flexible approach, which we believe will have a positive impact on the entire store visit. A positive store visit, we believe play a major role in consumers choosing to do their shopping in the store.The issue to be elucidated in this paper is; How do management and employees in a grocery store perceive that self-scanning influence consumers' purchase and the service the shop offers? Why would a supermarket use self-scanning as part of the service they offer to their consumers? The report concludes the similarities and differences experienced by administrative sales manager and employees compared to previous research on the subject.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.
