Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation
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.
Givarkonstruktion för beräkning av sådjup
This report shows the process of the development of a sensor module for the seed drills of Väderstad Verken AB. The module is supposed to replace existing solutions, provided that it is better from both a constructional- and an economical aspect. The purpose of the sensor is to continuously give the driver information about the level of height of the front- and drilling tools and the main purpose of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67.The methods applied have been taken from the book ?The Mechanical Design Process? by David G.
Distributionsekonomisk optimering av dagligvaruhandelns lokalisering : förstudie till ett forskningsprojekt
The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.
Patienters upplevelse av Basal Kroppskännedom efter avslutad behandling : En kvalitativ intervjustudie speglad ur socialkognitiv teori
Introduction: Basic Body Awereness Therapy (BBAT) is a treatment developed to treat different kinds of psychiatric diagnoses, but also to prevent the emergence of any other unhealthy conditions. The treatment is aimed to increase the body control and conscious breathing but also requires mental awareness.Aim: The aim of this study is to, based on social cognitive theory, describe patients' experiences of BBAT performed as group therapy.Method: The study design was qualitative with an inductive approach. Five people were interviewed after a BBAT group treatment in primary care. The data was collected by individual interviews with semi-structured questions and the interviews were analysed by qualitative content analysis.Result/Conclusion: The participants experienced increased body awareness and implemented BBAT strategies even though the treatment frequency was insufficient. BBAT was described as helpful used to regulate intensity level, stress management and facilitate breathing.
Underhållsstrategi enligt Professional Maintenance metodiken som en del av World Class Manufacturing
As a result of global competition, companies within the automotive industry are required to improve their production systems to achieve sustainable and competitive production. To attain operational excellence, companies have adopted concepts like lean and World Class Manufacturing (WCM).In order to deliver, companies need to increase the availability and reliability of production equipment. This demands focus on both operational and strategic maintenance, and efficient equipment acquisition and management. The main objective of this thesis is to identify processes and success factors that are necessary for improved maintenance performance. By conducting a case study and by performing a literature review, the following has been studied: 1) how companies within the automotive industry work with maintenance and maintenance strategies, 2) implementation of maintenance strategies, and 3) new acquisition and spare parts management for maintenance. The results show that basic maintenance concepts and related terms are well defined in the literature.
Regeringens transportinfrastruktursatsningar : En studie av tågtrafikens utrymme i regeringsanslagen för transportsektorn
In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for operation and maintenance of the railways are much higher then in the last government's bill. Furthermore the current founding of investment in railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.

AbstractSwedish tuition for immigrants (SFI) is a public adult education program in Sweden that was created in order to provide the immigrants with basic skills in Swedish. People with different backgrounds speaking different languages learn together how they should communicate in Swedish, both orally and in writing. For those who teach SFI it is important to know which factors have positive effects on the Swedish language acquisition. One of the questions to be asked is if the learning materials´ genre has any effect on the SFI students´ proficiency, in particular, oral proficiency. Scientists as von Franz, Vygotskiy and Bettelheim argued that fairy tales, as a genre consciously or subconsciously recognizable by all the people, present texts that are easy to acqiure.
De leende kvinnorna : en jämställdhetsutredning av en mandominerad arbetsplats
This essay is part of a project between Södertörn University College and Stockholm Academic Forum. The focus of the project is gender equality in small- and medium sized companies. I have worked with a construction company called Activa . The majority of the employees at the company were male and I was interested in the consequences of gender construction in such an environment. I think that the basic condition for equality work is an understanding of gender and the male norm.

Brand: "Øresund" - analys av regionen som territorialiserad simulering
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?.
"Varje lärare bör känna Gotland" "Det idealiska semesterlandet med de rika minnena" : Gotländsk skolresehistoria 1900-1940
This assignment focuses on the concept of ?school trips? and Gotland. Pedagogically, the school trip was initially focussed on practical and national aspects, the education to be made visible and the idea was to present Sweden, its nature and its industries. The Gotland administration chose to focus on the unique and cultural history, and it was unusual that visits were undertaken to factories and workshops. This was also the start of the current tourism trend where knowledge of the value of the countryside and the opportunities for tourism is a successful combination, which can be seen today even if the school trips now have different areas to visit.
Vanvårdens inverkan på nötkreaturs välfärd och hälsa
Farmers are required to make sure that cattles basic needs are met, but still every year cases of neglect occur where the farmer has not complied within the animal welfare law and regulations. The aim of this study was to investigate how cattle are affected physically and behaviourally by neglect in the form of underfeeding, starvation and lack of sanitation, which animals are most vulnerable to the impact and what prospects they have to recover. The study was conducted as a literature study and the results show that these types of neglect have a large impact on the cattle welfare. Underfeeding and starvation causes physical changes leading to reduced milk production, reduced muscle mass, impaired immune function, poor reproductive performance and changes in rumen microflora leading to decreased number of microbes and pH change. Physical changes due to the lack of sanitation consist of increased vulnerability to hoof diseases and mastitis, burns, and increased sensitivity to temperature.
