The military conflicts of the early 21st century have seen the introduction and rise of a new military technology: the armed drone. With the United States acting as the driving force behind this technological advancement, the U.S Air Force and intelligence agency CIA have madedrones their weapon of choice for pursuing suspected terrorists and insurgents in various remotelocations. American military leaders and policy makers assert that the armed drone?s high levelof accuracy make it the best available weapons platform for this task. However, new researchshows that the use of drones may result in more civilian casualties than previously thought, andmay in fact be more fallible than conventional aircraft in this respect.

The aim of this paper is to illuminate and discuss the political and ideological aspects of Early Medieval Nordic music. Due to shortage of sources, this issue has been overlooked until now. Did Early Medieval Nordic music meet the requirements for political and ideological use? In what ways could music potentially be used politically and ideologically? Was music used as a political and ideological tool? This is examined by a contextual analysis combining music history and historical archaeology. The survey consists of a background account, focusing on the potential of music and some requests for political use, and three case studies, where musical reflections of societal tensions is investigated in folk music lyrics, Icelandic sagas and church art.

This is a study of how four teachers work with pupils? early literacy learning. Interviews were conducted with two teachers who chose to use a specific method, Writing to Read (WTR), for teaching pupils to read, and with two teachers who had not chosen a specific method. The aim of the study was to compare how the teachers worked, their motives for their choice of method, and the ideas the teachers have about early literacy learning. To see whether the teachers? choice of method was related to the individualization of the teaching and their views of pupils? learning in interaction, Vygotsky?s theories about children?s learning have been used.

The purpose of the project has been to work out recommendations that reduce the energy-related costs and environmental impact of HPW Fresh & Dry Ltd., a fruit drying factory in Ghana. The factory produces electricity with diesel and biogas but also purchases electricity from the national electricity company. Heat for the drying process is produced from biogas, kerosene and solar panels. In the project the energy system was analyzed by measuring production and consumption of heat and electricity. The project results show that the factory can become self-sufficient on heat if the available energy is used more efficient. The production units for both electricity and heat have low efficiencies.

Nature and garden have always had meaning in human's life and succesfully seen as having health giving effects. Health is a state of equilibrium between physical, psychological, social and spiritual well-being. The individual's health is depending of how the society looks and how the individual manages to live her life in it. Stress is one of our time's large public health problems and leads in some cases to burned out syndrome. Stay in nature gives recovery according to theories of environmental psychology.

This thesis rewievs present day research on the settlement of Östra Aros in central Sweden. The thesis deals with the period from late Iron age to about 1270 AD, when the Swedish archdiocese moved to the already existing early-medieval settlement of Östra Aros, thus becoming the medieval town of Uppsala. The basis of the thesis is the study of a variety of source materials, such as artefact studies, runestones, topography and the prehistoric and early medieval hinterland. The thesis centers on archaeological excavation data and dating of settlement structures, particularly focusing on the settlements establishment. Through a critical review of primarily the written record and the archaeological data, the settlements characteristics and functions are discussed, emphasising when and if the settlement could be described as a town, central- or trading place..

To be able to read and write is necessary to manage well in life. It is important to get a good start in one´s reading and writing development. My purpose in this study was to find out how to teach children to read and write. Obtain knowledge about how to best help children during the early years of reading and writing development, and what is required to teach good reading and writing skills.I wanted to find out how the pedagogues work in the schools, and if they use ant special methods in their teaching. This is something that I, as a future pedagogue didn´t have much knowledge about, which is very important for my future pupils.My research method was qualitative where I interviewed three pedagogues who work whit teaching reading and writing in the early years.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

This thesis describes the processes of establishing wind farms in Sweden. The workcontains a thorough literature review regarding both the establishing process andproject management, including complex project theory. The main part consists of theexecution of 15 interviews with organizations involved in wind farm establishment.The result of these interviews laid the foundation for a process description identifyingdifferent steps and activities in these types of projects. The outcome was thencompiled in a project model, which includes five phases and four processes.When analyzing the project of establishing wind farms from the theory of complexprojects one discovers that the amount of different requirements and stakeholdersnecessitates a systematical and dynamical project structure. Since projects are in needof different types of competences there are also many consultants and contractorsinvolved.

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

The WT1 gene is a complex gene originally known to suppress cancer in kidneys. Studies of WT1 knockout mice have confirmed the important role of WT1 in the pathogenesis of Wilms? tumour, a tumour which counts for 95% of all childhood renal tumours. In that case the WT1 gene acts as a tumour suppressor gene. Subsequent research has shown that the WT1 gene in many other cases acts as an oncogene, e g in leukemia or lung cancer (even though these cancer forms can emerge as a result of many other aetiological factors).

This study deals with Swedish nuclear-energy politics from 1980 to 2006. The purpose is to trace and to explain change and stability in three political parties? rhetoric concerning the phase-out of Swedish nuclear-energy and the Swedish government?s nuclear politics. Two hypotheses based on path dependency theory are tested to analyze if rhetoric and politics are developing in separate directions. The first hypothesis is based on the idea that earlier promises from the political parties affect what promises they can make later on.

The concentration of acute phase proteins in serum is altered as a response to inflammation, infection or trauma. this makes these proteins potential biomarkers of unspecific pathological processes. In cattle, haptoglobin and serum amyloid A are the two acute phase proteins that show the largest increase in serum concentration as a result of inflammatory processes. The haptoglobin concentration has been shown to correlate to clinical signs as well as inflammatory processes found at post mortem examination. This feature could be useful prognosis of the individual as well as for monitoring the health status of a herd or identifying carcasses that shold be examined closer at the slaughter-house.

Due to the Danish kings? engagements on the British Isles, the early town of Lund, was influenced by English and Anglo Saxon traditions, architecture and technology. The main aim of this essay is to find out in what ways, and most importantly how this can be seen in the archaeological material, and how it changes over time. Within a framework of historical sources, archaeological finds like excavated stave and stone churches, cemeteries, pottery, and everyday personal objects, both English immigrants and English influence is found. The problem of the English origin of the palisade wall technique is discussed, as is early Lund as a Viking age town.

The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted.LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.
