This literature research is meant to answer the following questions: ? What was the Swedes consumption of fat from 1935 to 2009? ? How has the fat consumption corresponded to the current recommendations? ? What is LCHF and which are the main advantages and disadvantages? Fat supplies us with energy, isolates and protect organs from bumps and punches. Fat is insoluble in water but soluble in organic solvents. The properties of a fat depend on its structure. The most common fat in human food is triacylglycerides.

The aim of our study is to ascertain whether a hanging suspension fluorescentlamp for a private home environment is going to be attractive for a largeaudience. We want to open up for new uses of fluorescent lamps as lightsources.The main approach in this work is how to design a fixture with fluorescentlamps as a light source that will meet the requirements and requests of thehome environment could look like. At the same time we want to make a newimpression of how a fluorescent light source.Primarily we used a quantitative method, but this was rejected after a pilotstudy. Instead we used a qualitatively based method in the sense that weconducted a group interview as well as individual interviews.Based on data from the interviews and our preliminary work a prototype wasbuilt. This prototype is a fluorescent fixture equipped with 2x14W T5fluorescent lamps, dimmed separately.

Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

En studie om varför konsumenten inte köper ekologiska livsmedel?Författare: Helene Kaspersson 850325                 Jennie Spångberg 860813                 Stefan Sjöblom 871231Handledare: Claes JonssonProblemformulering: Varför köper inte konsumenten ekologiska livsmedel?Syfte: Vi har för avsikt att beskriva hur konsumenten påverkas av individuella influenser och gruppinfluenser till att inte köpa ekologiska livsmedel. I en förlängning skall denna uppsats kunna vara till hjälp i processen att öka försäljningen av ekologiska livsmedel.Metod: För att kunna ge en generell bild av beteendet utförs en kvantitativ undersökning i form av en enkätundersökning.Teoretiskt perspektiv: Studien har köpbeslutsprocessen som utgångspunkt med fokus i hur konsumenten påverkas av individuella influenser och gruppinfluenser.Slutsats: Vi har kommit fram till slutsatserna att kunden agerar utifrån ett vanebaserat beteende vid köp av livsmedel. Det finns en stereotyp som symboliserar den ekologiska konsumenten. Kunden påverkas av sin referensgrupp till att inte vilja sticka ut.Nyckelord: Konsumentbeteende, Köpbeslutsprocessen, Influenser, Ekologiska livsmedel.

The Swedish public procurement correspond to approximately 400 milliard Swedish crowns every year which corresponds to about a fourth of the Swedish Gross National Product. Setting proper demands in the procurement is a useful tool to drive the development towards more environmentally adapted products and provisions. The Act on Public Procurement (Lagen om offentlig upphandling, 1992:1528) gives the municipalities opportunities to consider environmental properties during the procurement. This combined literature and empirical study investigates the experiences made by the three municipalities Ludvika, Borlänge and Smedjebacken during the process of certifying their school kitchens as organic in cooperation with KRAV. The main conclusion is that without compassion and curiosity for developing a green public procurement changes can be hard to implement.

The main purpose of the project was to identify potential environmentally harmful substances which can be leached from rubber asphalt. A method for analysing asphalt was developed and three rubber asphalt materials were analysed after being cryogrinded. One of the materials was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials.The asphalt materials were leached by water during 24 hours. The leachates were extracted with dichloromethane, dried with sodium sulphate and concentrated to a small volume.

Deep litter is a system for animals kept in separate stalls, loafing and bedding in wind shelters. The litter can consist of different bedding, like straw and peat. The system is allowed to build over and to ensure optimal proportions it is necessary to add new straw regularly and to have good conditions. Important conditions are aerobic state, humidity, amount of organic substance and acceptable temperatures in the litter. The micro organisms are depending on temperature for their living conditions and to get the bottom layer in the litter to start burning.

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

The quality of meals is included in the constant improvement of each preschool. The study is carried out on behalf of the City of Malmö and Environmental Management and focuses on this quality work. By compiling a checklist of meal quality and by identifying what the meal quality means for persons working with the meal (managers, cooks, educators and parents), it is our wish that this will be a help in their quality work. To inspire the composition various organizations working methods and ways to manage, evaluate and make use of different models and tools to improve the dining quality, has been studied. In the literature, the work has received confirmation of theories that emerged during the analysis work of what a meal is and how quality can be measured. The results show that food quality is described as a complex concept consisting of different parts, where the food, atmosphere, service, together form the meal quality. The semi-structured interviews and the inquiry form, have given an indication of the preschool work with quality in the meal activities and it shows that on a wide range and large differences.

Since a couple of decades the community of Jönköping has worked out an urban vision of how the city should be appropriated expanded. The prospect extends to around year 2040 and deals with the area south of lake Munksjön in Jönköping, Sweden. Today there is a proposal of how this would look like and what main public functions that should be located there. One issue in the so-called urban vision 2.0 indicates a congressional building. This report describes how such an object can be designed according to the urban vision conditions.The work is focused on three main themes;* Architectural concept and a modern form of expression.* A functional attractive congress building in a new planned town centre.* General concept of a realistic structure system that meet the spatial and architectural possibilities.Various concepts in the meeting industry and in the architecture field are identified in order to understand the concepts and ideas with today´s congress buildings.

The present study discusses the metabolism of ethanol in the human body from the ingestion of ethanol to the excretion of its break down products water and carbon dioxide. Ethanol is a small molecule, soluble in water as well as in organic solutions. It is quickly distributed to every section in the body, where it exerts a direct toxic effect on the cells. Ethanol cannot directly leave the body efficiently so it needs other metabolic pathways. The molecule is metabolized by oxidation, predominately in the liver.

Idag är det inte många textilföretag som har möjlighet att ha strumpproduktion i ett land som Sverige på grund av lönsamhetsskäl. Det är billigare att producera i låglöneländer i Europa eller Asien, men det tär istället på våra naturresurser och vår miljö att transportera produkter fram och tillbaka. På grund av de höjda lönerna i Kina och valutakursen för euron som höjts drastiskt i Europa har Sverige dock kommit till ett läge då det blir ekonomiskt lönsamt att flytta tillbaka en del av produktionen till Sverige. Dessutom ökar trenden med ekologiska och närproducerade varor, vilket ökar efterfrågan på svensktillverkade produkter. Studien syftar till att ge privatpersoner och företag ett underlag till att undersöka sina möjligheter för produktion av strumpor på den svenska marknaden.Utvecklingen av strumpproduktionen i Sverige pågår hela tiden och företagen uppdaterar sina maskinparker och utbildar sina anställda, vilket leder till en utveckling av marknaden.

The purpose of this thesis has been to assess whether leaching from one particular Swedishlandfill site, Skörbytippen, is contributing to elevated levels of heavy metals in a ditch runningfrom the landfill site to the lake Mälaren in the communal region of Håbo kommun. Since theditch is stretching approximately five km downstream from the landfill site, in situ observationsand maps with known points of inflow was utilized to determine appropriate test points for thecollection of samples.Soil, water and sediment samples were collected and analyzed for content of organic material, pHand conductivity. Data on plant-available elements and total amounts of heavy metals wasacquired through ICP-analysis.The results show that the Skörby landfill is currently in the methane-forming anaerobedevelopment phase, which indicates that the concentration of free and complex-bound metals inthe leachate water should be low due to chemical binding with other landfill compounds. The pHof the sediment samples was generally one unit higher than the soil samples and some of themeasured data, such as pH and conductivity, show that an environmentally disturbing dischargeof some kind of strongly alkaline chemical(s) has been made from Benders? takpanneindustri inclose proximity to the landfill.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.
