Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.

The aim of this study is to find out if, and in what way the Maasai pastoralists affect the spotted hyena (Crocuta crocuta) through Bomas (Maasai settlement) and keeping of livestock. The study was carried out in the Maasai Mara National Reserve and the adjoining group ranch, Koyake GR, in South-western Kenya.Data was assembled through transect driving, with instantaneous scan sample during two seasons, December 2003 and May-June 2004. Study area contained 12 bomas with three different type of transects each: T1 (0.5 km from boma), T2 (3 km from boma) and T3 (5.5 km from boma), to create a gradual decline in human and livestock impact. Results show that there are differences in the hyena's utilisation of transect type during the day and during the night. The spotted hyena tend to avoid transects close to the boma during the day time, but go there during the night time.

In this thesis we have tried to answer the question of whether or not the peaceorganizations working in Israel and Palestine have an impact. We have answered the question by analyzing six different organizations; three who work with children and the other three with women issues. The analysis contains a case study of each organization and then a comparison between the two groups. This study is built on theories about; grassroots organizations, women in organizations and intergroup communication. Our conclusions in this thesis show that there are some similarities between the groups as well as there are differences.

The aim of this study is to examine the conditions for participation in women's networks for the members of the Geek Girl Meetup network, to expose the members' perceptions of the IT industry and to highlight the network's impact on women's situation in the IT industry. The empirical material consists of interviews and a survey. The interviews were carried out with the network leaders for a better understanding of the network structure and why it exists. The survey completed by the members illuminates how the members perceive the networks function in the IT industry and what kind of an impact the network has on the members and if it has any at all. The result of the study shows that participation in networks like Geek Girl Meetup can be a model for promoting gender equality and improving conditions for women in the IT industry.

The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.

Abstract In order to make the modern agriculture less dependent on non-renewable external inputs, it has to rely more on ecosystem services. The agricultural system produce not only food, fiber and fuel, it also generates other ecosystem services such as e.g. photosynthesis, recycling of nutrients, influencing local microclimate, pollination, biological control and detoxification of noxious chemicals. This study is an attempt to get a better understanding about the interaction among different ecosystem services and different habitats capacity to generate them. An evaluation of eight different methods is done. The ecosystem services studied are the ability to absorb solar energy, biomass production, botanical diversity, decomposition and natural predation of aphids.

The purpose of this essay is to examine how out-pedagogy, drama and art can be used as means of promoting language development of bi-and multi-language learners, and to show what benefits these three methods offer to children of year three of an elementary school in Stockholm City. This is a small survey of work-style and the results are based on observations and interviews with five teachers which included three class teachers, one resource teacher and one other language teacher and it was carried out two full days of observations in both classroom and outdoor environment. In this work, I note how out-pedagogy, drama and art can help bi- and multilingual children develop language. My study shows, in accordance with the respondents interviewed, as well as research in general that out-pedagogy, drama and art is language development practices. They argue that out-pedagogy and the aesthetic elements promote language development of bi- and multilingual children in different ways and complements the traditional approach.

[?If we zigzag in the middle, it?s OK?] The purpose of the following study is to examine the relationship between tourism and religion in a Balinese context. We look specifically at changes in religious practice, culture and mentality, as well as how religious philosophy is used as a tool for limiting the negative impact of tourism. The methods used are semi-structured interviews and participant observations. Central themes in the following essay are globalization in the form of tourism, westernization, subsystem theory and capitalism, which also make up the theoretical framework.

Smallholder farmers in low-income countries face a number of challenges in animal production. Animal husbandry carries great potential in reducing poverty, hunger and gender inequality, but at the same time infectious diseases are prominent threats to farmers? livelihoods and their animals. The objective of this study was to investigate the socioeconomic impact of infectious animal diseases on smallholder farmers in low-income countries, using African swine fever (ASF) in Uganda as an example. The study was conducted in two parts. The first part of the study was questionnaire-based and performed in Gulu district, northern Uganda.

This study is based on an ongoing debate regarding the Stockholm Stock Exchange, which centers around the possible abolition of quarterly reports. The purpose of this paper is to contribute to this debate by examining how the relationship between financial reports and stock price correlates. The study's methodological approach is based on the Capital Market Research frame-work in which an ERC model and an extended model are used to measure the relationship. Three hypotheses were formed to categorize the direction of the study, these categorizations treats the differences in impact between quarterly and annual reports on stock price, as well as differences in impact as a casual effect of company size and seasonal sensitivity. The results of the study show that quarterly reports have a stronger impact on the share price than annual reports.

This thesis concerns to investigate renovations of existing buildings aiming at enabling energy efficiency, from a conservation and restoration perspective. This includes performing case studies of three projects in the Gothenburg area where renovations has been done and an analysis of directives raised by the EU and later implemented by the Swedish National Board of Housing, Building and Planning, Boverket. In addition to these, regulations enforced by the Swedish law, related to the topic, have been considered.The investigated projects in this case were the housing cooperative Välten in Brämaregården, the Solar Buildings in Järnbrott and Gårdsten as well as Katjas Gata 119 at Backa Röd. In order to measure and compare the results of these projects a comparison between the pre- and post-restoration energy consumption have been performed. To capture additional perspectives the grading system Operation Kungsörn has been applied.Regarding the comparison of energy consumption the renovation of Katjas Gata 119 was found preferable but showed in my view lacking attention to the cultural heritage of the area.

Lymphoma is a group of malignant tumour diseases developing in the secondary lymphatic system. These diseases can develop in all organs as lymphocytes are ubiquitously in the body. In connection to mucus membranes we find mucosa-associated lymphoid tissue, MALT, in which lymphoma can spontaneously but slowly develop, mostly at chronic inflammation or at autoimmune diseases. Today these diseases are incureable with the exception of some cases caused by Helicobacter pylori-infection. Antibiotic treatment of these cases can induce remissions.MALT-lymphomas have characteristic histological and molecular properties.

A Monte Carlo simulation of the ELECTRA reactor using (U,Zr)N fuel and a liquid lithium coolant is performed using the Serpent simulation code. The results show a reactor with a total reactivity coefficient of the coolant, fuel and material expansion that is strongly negative. These properties make the ELECTRA reactor a good candidate for a safe space reactor that could be used for propulsion of manned and unmanned space vehicles to Mars and other parts of our solar system..

The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.

The purpose of this thesis has been to gather knowledge about the complaints of tying-up in horses and to show that the importance of feeding. The thesis includes a literature review of tying-up how preventative measures by feeding can be made. In the equine sport, crosscountry, horses occasionally suffers from tying-up, a muscle disease. An increased knowledge about the disease is demanded by riders and trainers as the disease disrupts training and competition of suffered horses. A cross-country horse works very hard in training and during competitions but the work bouts are long enough for the muscle cells to use aerobic pathways in the metabolism.
