Vedrötor i stadsträd : biologi, detektionsmetoder och förebyggande åtgärder
Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.
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).
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.
Utvärdering av jetomrörning : En studie gällande utvärdering av omrörningssystem vid Ekeby reningsverk
Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.
Gymnasiereformen 2007 : En studie om förändringarna inom biologiundervisningen och hur en öppen process bemöts av aktörer i skolans vardag
Next year, Swedish upper secondary school will be the arena for a new comprehensive reform according to an extensive government bill. The reform will probably have major impact on every-day educational practices. The aim of this paper is to describe the consequences forbiology teaching when the reform is implemented, and to analyse in what way the biology teachers, and other participants, take part in digitised discussion forums during the implementation of the reform.The research design consists of a quantitative approach and two different methods are used, i.e. descriptive content analysis and quantitative content analysis. The content and meaning of the government bill is analysed and the statements from the participants at the discussion forums are equally important in order to fulfil the aim of this inquiry.The results show the reform will have a profound impact on the subject biology, e.g.
Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasin
Löslighet och transport av sällsynta jordartsmetaller i Källfallsfältets gruvsandsmagasinHugo de Campos PereiraSyftet med detta arbete har varit att kartlägga vilka mekanismer som styr lösligheten av sällsynta jordartsmetaller (eng. rare earth elements, REE) i sulfidhaltig anrikningssand vid den föredetta gruvan Källfallsfältet i Västmanland. För syftet har markvatten- och grundvattenprovtagning utförts, tillsammans med laktester och geokemisk modellering med Visual MINTEQ ver. 3.0.Resultaten visade att sulfidvittring är den främsta processen som styr pH i anrikningssanden, och därmed också indirekt REEs löslighet. Däremot är sulfidvittring ingen källa till REE i sig då ämnena inte föreligger sulfidbundna, något som oxiderat tillgänglighetstest NT ENVIR 006 visade.
Framsta?llningen av barn i den nya sexualbrottslagen : en inneha?llsanalys baserad pa? fo?rarbeten
The last major change occurred in 2005 when the new sexual offenses law came into force with an increased focus on children. The purpose of this study is that through a content analysis to identify and understand the construction of children in the new legislation on sexual offenses on the basis of preliminary work. Based on the purpose we came up with two questions: How are children constructed in the preparatory works to the new sexual offenses law? Are they attributed to child characteristics and responsibilities in the new legislation on sexual offenses and if so, how? In order to achieve the purpose of the study we have chosen the preparatory works to the new legislation on sexual offenses from 2005 until today. The study's empirical work has been further narrowed to the children, which means that a distinction is made in the new legislation on sexual offenses to 6 chapter 4-6 §§.
Uthållig sanitet : en förstudie i staden Picota, Peru
The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015.
In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well.
In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact.
In this study three different sanitary systems and the effects of different population growths were compared.
