Extramural English Activities. Teachers? perceptions of students? extramural English activities in relation to vocabulary

Because of the globalization of society, English as a foreign language (EFL) has become easier to access through internet and outside school English activities, so called ?extramural English activities? (EEA). Previous research indicates a positive relation between pupils? EFL vocabulary development and EEA (Sundqvist, 2009). This development may influence teachers? lesson planning, because of pupils? wide span of interests and the resulting different levels of EFL vocabulary.

Studie av värmeflöden i befintligt bostadsbestånd : Utvärdering av energieffektiva besparingsåtgärder

The purpose of this master thesis is to investigate different types of measures for making buildings more energy efficient and to estimate their profitability. The calculations were performed with the building simulation program VIP+ and the evaluation of the profitability with the life cycle cost method. Furthermore, it was examined how losses in the distribution of secondary systems of district heating can be avoided. Options to replace district heating with a local district heating system based on bio-energy have been investigated. The possibilities of achieving more efficient thermal energy consumption and production for the chosen estate were also examined.The object of the study has been a residential estate with 133 detached houses in Uppsala, built in 1974.

Kalvhyddans utformning : påverkan på kalvens hälsa och komfort

This paper aims to, through a literature review, examine how to best design and adapt calf huts to meet the calf's physiological requirements and reduce the infection pressure for enteric and respiratory diseases. It illuminates how the calf relates to different temperatures and climate, which temperature control mechanisms it uses and its ability to perform these regulations, as well as providing a summary of the past decades´ research on the calf huts housing system. These two theory chapters, along with a concluding discussion, provide a better understanding of how to, especially in temperate climates, design the most suitable calf hut, which cater to the calf's both thermal comfort and physical health. The literature suggests that the calf's own temperature control works well to counteract the temperature outside the desired range, and that one of the most important factors rather is ventilation of a calf hut, which reduces moisture and pathogens. The conclusion of this paper is mainly that there is not an obvious way to place and construct a calf hutch and that most design principles contribute to both positive and negative effects simultaneously.

Krafter på rörsystem vid transient flöde : En jämförelse mellan RELAP5 och Fluent

At Forsmarks Kraftgrupp AB (FKA) forces on pipe systems due to transient flow are frequently calculated as a step to verify their structural integrity. In nuclear industries these forces are often calculated with a one dimensional thermal-hydraulic analysis-code called RELAP5. When calculations regarding more complex geometries are needed, the three dimensional code Fluent is often used. This code is highly time consuming and requires large computational power.This projects aim is to compare calculations of pressure, flow and forces carried out by RELAP5 and Fluent for an arbitrary pipe section during transient flow conditions. This has been accomplished by constructing a simple geometry for which a transient flow is simulated in both programs.

Matematik och modersmål : Pedagogers syn på modersmålets betydelse för flerspråkiga elevers matematiska förståelse

This research is about how the educators view the best way to help multilingual students develop their understanding for mathematics. The aim of the study is to identify the different aspects from the teacher?s point of view of this new approach of teaching: what are the limitations versus the opportunities? The study is limited to a multicultural school in Stockholm and to the experience of a few class teachers and mother tongue teachers.A qualitative approach was used and the interview was selected as the method to collect the data. Three class teachers as well as three mother tongue teachers were interviewed about their experiences. The interviews were recorded and transcribed word by word.There have been discussions about the skills in mathematics in multilingual speaking students, and that their greatest obstacle of understanding mathematics is that they are being taught in another language than their own mother tongue.

Universitetsstudenters kostvanor : En tvärsnittsstudie om en grupp universitetstudenters upplevda kostvanor och kunskap i ämnet samt hur de upplever hälsotrenden.

Background:Studies show that when nurses are experiencing problems in the care of non-Swedish speaking patients, it is often due to obstacles in the communication. Studies also show that a prerequisite for adequate care is that there is a basis for a direct communication. Nurses perceive interpreters as an important link to the patient when they do not share a mutual language, the nurses perceive interpreters as a bridge in the conversation.Aim:The purpose of the study is to describe nurses' experiences of the quality of assessments done with the help of an interpreter.Method:The study was conducted through interviews with ten nurses, working at psychiatric clinics. Qualitative content analysis was used for the analysis, which resulted in five categories.Results:The analysis resulted in one theme: "it´s the interpreter who tells me and have not the feeling that the patient has" and five categories: "shades of the language", "conversation structure", "the interpreter's competence", "interpreting implementing" and "the interpreter's gender and origin". The nurses experience working with interpreters as a challenge.

Produktivitetsstudie Brobyggnad

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Miljö- och samhällsekonomisk analys av behandling av biologiskt avfall

Biogas is a renewable fuel that can be extracted from anaerobic digestion of many differentsubstrates, for example biological household waste. An alternative handling of the waste is tomix it with other wastes and incinerate it in a combined heat and power (CHP) plant. Thisstudy uses life cycle assessment to investigate which type of waste handling that is betterfrom an environmental point of view, anaerobic digestion with biogas production orincineration. The results are based on a case study of a biogas production plant owned by thecompany Ragn-Sells in Vänersborg. The alternative is incineration at a CHP plant inGothenburg.

Energikartläggning av biogasanläggningen, Kungsängens gård

The purpose of this thesis was to make an energy survey and quantify energy flows of individual unit operations associated with the biogas production in Uppsala Vatten och Avfall AB:s biogas plant, located at Kungsängens gård. Moreover, large consumers of energy would be identified and analyzed. The objective of this energy survey was to obtain a detailed understanding of the energy use in the biogas production.The energy survey was divided into two parts: electricity and heat. Each part was treated separately and with somewhat different approach. To estimate the electricity usage during the projcet the rated power of each selected unit operation was noted and multplied with thenmeasured time of usage.

Konstruktion av formkropp pa JAS 39 E/F Gripen

The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

Känslan i bilden : Sociala taggars användbarhet vid bildsökning i Flickr

Image indexing research today is either conducted on a visual attribute level or on a higher semantic level, forming a semantic gap between the two. There is much to gain if research progress from the two fields is combined. Image retrieval using access points in both visual and semantic significations could improve retrieval and bridge the gap. In social media today, images are often the primary communication agent and the number of images on the web is increasing in an uncontrolled way. New and efficient ways to index and retrieve the images are needed.The purpose of this study is to examine if emotions could be a semantic access point for image retrieval and if folksonomy indexing is useful when searching for images that represent emotions.

Konceptstudie av Waste Heat Recovery System på Tunga Fordon

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.

Kompetens som lockbete : En studie i lokala och centrala biblioteksföreträdares syn på marknadsföring av bibliotekariekompetens gentemot lokala politiker

The aim of this study is to explore if and how library managers market their competence in communication with local politicians. It is also our aim to find a definition of the competence of librarians. The report identifies and describes problems and possibilitieswith marketing of competence to politicians on the basis of one Swedish municipality's library managers. In order to fulfil this aim we have used a literature study on marketing, competence, the political process and the librarian profession. We have alsocarried out an empirical study where we interviewed ten library managers in onemunicipality, seven politicians in the same municipality and ten representatives for central professional organisations mainly in Sweden.The results are that most library managers don't market their competence because they don?t believe in marketing competence.
