Det energiproducerande huset
We are heading towards a huge switch of how energy is produced with fossil fuels being replaced by renewable energy sources. It is not difficult to replace the energy you use in the house and there is no need for futuristic technology. There are already many established products on the market such as high efficiency vacuum solar collectors, heat pumps & small wind power stations that can supply the energy being used in a house. The company Sol & Energiteknik SE AB in Huskvarna has many different products which can reduce the need for an outside energy distributor. An average house in Sweden uses 15 000 kWh for heating, 5000 kWh for tap water and 5000 kWh for electricity.
Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
Tycker de olika? : En kvantitativ undersökning av gymnasieungdomars syn på och attityder till svenskämnet med avseende på programkaraktär
The main purpose of this study has been to survey the pupils? general comprehension of the content and aim of Swedish as a subject in upper secondary school and their attitude towards the subject. Furthermore the study aims at discerning whether there is a distinguishable difference between programmes with vocational and academic character.The study is based on the results of 101 answers from students in an opinion poll handed out at a Western Swedish upper secondary school. Throughout the analysis the results of the two programme groups have been weighed against each other. The result of the survey shows that:? The understanding of the aim and content of Swedish at upper secondary school is acceptable as a whole.
Bekämpningsmedelsrester i dricksvatten : En undersökning av bekämpningsmedel i 50 enskilda brunnar i Laholms kommun
AbstractThe knowledge about pesticide residue in private wells is not well documented in Sweden.Previous studies have detected pesticide residue in private wells, this issue is what made themunicipality of Laholm commission the study. The purpose was to collect water samples from50 private wells in Laholm and have them analyzed for traces of pesticides. The wells in thestudy are spread geographical over the entire municipality. The analysis of the water sampleswas carried out by the accredited laboratory Eurofins. Nine of the 50 wells in this studycontained residue of pesticides and two of these exceeded the allowed concentration of 0,1 ?g/l.Nine different pesticides were detected, among these were BAM, Atrazin and breakdownproducts from Metribuzin.
Lgy11: en kontrollerande läroplan. Samtal med fyra gymnasielärare
The autumn of 2011, saw a new curriculum being put to use in Swedish schools, a curriculum whose purpose was to supply the Swedish schools with a larger national equivalence. This new curriculum was meant to counter the strong variations in grading that the ministry of education felt was a result of the Lpo94, the curriculum previous to lgy11's introduction.With the introduction of the new curriculum there followed some changes to the objectives and emphasis on content prepared by teachers in the subject of religious studies. As a result this also affected the teachers planning and execution of the course and its content. From the perspective of a teacher-to-be I hold a great interest concerning how lgy11 affected the religious teachers planning of their lessons and teachings. This essay is written with the hope of being able to determine how some of the now active teachers perceive that they have been affected by the curriculum in its structure of teaching and planning and the content of material.
Ur ett genusperspektiv : En kvalitativ innehållsanalys av två utbildningsprogram: Home Farm Twins och Rena rama forntiden
Our aim with this study is to investigate whether or not Utbildningsradions - which is a public broadcasting agency - educational programmes reproduce the existing gender patterns of the female and male genders. We have chosen to analyse two educational programmes, Home Farm Twins and Rena rama forntiden.We use a social constructionist theory regarding the construction and reproduction of gender and the method we have chosen to use is a qualitative content analysis to study the educational programmes.Our conclusion is that in the case of Home Farm Twins, it reproduces the current stereotypes that exist in society. Rena rama forntiden on the other hand does not, the program has got a clear gender perspective in regards to its content. Though it can be said that in some ways it does not reflect upon the gender patterns that exist in society today, to a satisfactionary extent.Utbildningsradion does not achieve its policy concerning Home Farm Twins, but on the other hand it shows that in the case of Rena rama forntiden they do own up to the standards regarding cultural diversity and creative aim..
Brand Culture : Between consumers and brands
The empirical data that lies behind this survey comes from field work between 1992 and 1995. This field work represents work I made myself as a sales-man for the company, Malmberg Original Water. The task was to implement the Malmberg mineral water brand on the restaurant market of the South-Swedish area. Our aim was to reach the upper-scale, premium market of restaurants. The mission was successfully completed, and at 1996 we had completed the position as the most exclusively positioned mineral water brand in Skåne (Southernmost Sweden).
?Det finns ju inte med i boken, ska jag kunna det ändå?!? : en studie om elevers övertro till läroboken som angivare av kunskapsmål samt vilken misstro detta skapar till all undervisning som går utanför dess ramar
The purpose of this study has been to get a deeper insight into how students reason about the textbook and teaching that goes beyond its content. This in order for the teacher to be able to consider and respond to these important attitudes already at the planning stages of such teaching situations. This approach will aid to help students overcome the distrust of things that are not in the textbook.The study shows that students have an attitude of overconfidence to the textbook's reliability. It is considered to be controlled in its content as well as being a reference on the extent of the knowledge content.The general approach to teaching that deviates from textbook structure is that it is welcomed as an interesting feature. However, a questioning attitude soon appears about whether the element will be included in any requirements for knowledge or tests.The following important conclusions can be drawn after this study was carried out:Very clearly communicate the purpose of all education that deviate from the textbook.Inform students about the textbook's deficiencies and the need for supplementing.Accept and respond to students' focus in that grades are the main driving force for the acquisition of knowledge in high school..
Vem är rädd för bannern där? : En studie om banners klickfrekvens
This paper is about advertising on the Internet using banners. Together with Embryo Webbyrå we have tested a lot of different ways of advertising on the online newspaper of Göteborgs-Posten, gp.se. Two of the web bureau?s existing clients, Resia and Recip, were chosen for the ads and the whole campaign lasted a period of four weeks.By comparing our banners with the consideration of format, color, placement and content we wanted to find an answer to how the most optimal banner would look.Our test result shows that visitors rather do not want to click on a banner, although we think that we have seen some interest and curiousness from visitors in the banners content. Even when the visitor does not click on a banner, the message might be put in mind for a future purchase or act..
Språklig variation i svenskundervisning : En studie om hur språklig variation, dialekter och sociolekter behandlas i Svenska 1 av utvalda lärare och läroböcker.
The aim of this study is to look at the way four teachers in, and five workbooks for, the course Svenska 1/A+B in upper-secondary schools include language varieties in their content. The research is based on qualitative and quantitative analyzes of the workbooks, where words and content are examined, and also interviews with the teachers who presents how they work with language varieties in their education. The results show that language varieties are accepted in school-education at the same time as they are, and have been, alienated in a way. The results also show that language varieties are less prioritized than other areas of education in the same subject..

Beror KRAV-grisars ledanmärkningar på miljöfaktorer?
This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.
Dietary fibre composition and sensory analysis of heat treated wheat and rye bran
When grains of wheat and rye are conventionally milled, large quantities of bran classified as by-products are left and are mainly used for animal feed. Bran is a complex material composed of the aleurone layer, nucellar epidermis, a seed coat, a fruit coat and a small proportion of the germ and endosperm depending on extraction rate. The bran fraction consists of approximately 40-50 % dietary fibre which can contribute to increase the nutritional quality of human cereal food. It would also be valuable for the food industry to convert by-products as bran to products with higher commercial values.
The aim of this thesis was to analyse the content and composition of dietary fibre of heat treated wheat and rye bran according to the Uppsala method with some modifications in order to analyse soluble and insoluble dietary fibre separately. Half of the bran samples were precooked, dried and roasted and the other half dried and roasted (uncooked).
The bioavailability of soluble oxalates in stir-fried silver beet leaves
The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.
Förändringar i markanvändning över tid och dess påverkan på vattenkvalitet
The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.
