Cultivable land is a limited resource and agriculture contributes to some of the most serious environmental problems facing the planet like, global warming, eutrophication and loss of biodiversity. The specialized, industrial agriculture with monoculture and extensive input of external energy, commercial fertilizer, and chemical pesticides are all essentially unsustainable. An adaptation to other methods of production is necessary to preserve the environment for future generations. The aim of this study is to describe the factors that distinguish sustainable from unsustainable agriculture. The results will be used to examine if and how the European Union (EU) works in order to create a more sustainable agricultural industry and to analyze the preconditions for such development.

Commonly held dietary guidelines discourage full-fat dairy consumption due its to high levels of saturated fatty acids, which are believed to aversely influence cardiovascular disease risk. Cardiovascular diseases cause more than one third of deaths in the developed world. With dairy often providing a large part of energy and nutrients in Western diets, research into its effects on human health is warranted. Several recent studies have suggested a protective role of dairy in the development of cardiometabolic disease. However, many of these have used imprecise methods of dietary assessment, based on questionnaires or interviews. Biomarkers are emerging as a means of evaluating diet in a more objective way. Currently used dairy fat biomarkers are minor fatty acid constituents of dairy that preferably are unique to dairy and not influenced by endogenous metabolism.

It is estimated that 22 000 contaminated areas exist in Sweden today. In order to classify the risk of contaminant migration from these areas and to prioritize which of these contaminated areas should first be treated, the Swedish Environmental Protection Agency (EPA) has designed a method, for the investigation of contaminated areas (MIFO). One of these contaminated areas is the landfill Gräsötippen outside Köping. The landfill has been used by both Yara AB and the Köping municipality between the years 1945 and 1975, and both industrial and household waste have been deposited there. The aim of this report is to survey which contaminants that can be found in the soil and water in the landfill Gräsötippen and to evaluate the migration of these contaminants.

In a society where children are getting a bigger influence over the family?s consumption and where more products for children are purchased, the market for children products has expanded. This growth is due to a higher amount of older parents which have a god economy and are choosing to spend more money on products for their children. Also the fact that parents use fashion products for children as a way to reflect their own status and that children are becoming more fashionable and aware of trends have contributed to the markets expansion. All together this leads to a grown importance of knowledge for marketers concerning the market.

Our purpose in this paper is to examine if there is any profitability for a company with a factory in the timber industry to invest in a combined heat and power, CHP. Based on analysis and the results that the paper generates, we will give Derome AB a suggestion on how it is a profitable investment or not to installing in a CHP.By investing in a CHP plant, you can get a high efficiency, which means that companies can use their resources more effectively. The Swedish wood industry has by-products of production that can be used for combustion in their boiler which is an advantage.The essay is a qualitative study where we have a case company, Derome AB. In this company, we interviewed two employees who have knowledge in the study. They have helped us to provide information and data about their business.We chose to use the pay-off- and the net present value method, NPV, to see if there are profitable advantages for the investment.

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

Syftet med studien är att undersöka attityder till inälvsmat. Synen på inälvor som mat är varierande beroende på land och kulturella skillnader och ses i vissa kulturer som delikatess och i andra som skräp. Med inälvsmat menas ätliga organ ifrån slaktdjur. För att få veta om benägenheter att konsumera inälvsmat finns måste de faktorer som avgör personens matval studeras. För att svara på denna fråga utformades en egen teori som beskriver de beståndsdelar som ligger till grund för människors konsumtionsval.

Modern societies are generally becoming increasingly capitalist in nature and economies of these societies are thus likely to become more focused on consumer consumption. Advertising plays a vital role in contemporary society where we, as consumers and citizens, are surrounded by it everywhere we look and everywhere we go. This puts pressure on advertisers to become more creative and to explore new ways of marketing their products and services in an already saturated environment. We believe that the added pressure and the already established role of marketing in society make advertisements an interesting and telling object for analysis. This is particularly the case with regards to the concept of selling and marketing products that have qualities that are known to be less than beneficial for our health.This paper analyzes four commercial advertisements marketing beer; a product that we argue has qualities that can be seen as potentially bad for the health of individuals and for societies.

The aim of this study was to develop a simple model for calculating stock costs for bio fuel at Billerud Karlsborg and subsequently recommending a suitable stock level of bio fuel. The stock components considered in the model are GROT (branches and tops), bark, dry wood chips, raw wood chips from barking and sawdust. The calculations are based on a probability distribution of historical deviations between ordered and delivered volumes. The model presents two different ways to manage the supply in case of irregular deliveries. The first way is to stock enough volume to cover the deviations and the second way is to compensate with a quick purchase from the spot market (at extra high purchase prices).

Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.

Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

Launching and marketing a health food product is associated with larger problems than a launch of a traditional food product. There are several sales channels that can be used for a health food product, for example the product can be sold as a traditional food product, natural health food product or as a prescription drug. A smaller company can however experience problems while launching its product as a prescription drug because of the large costs associated with this particular sales channel. There is often no other alternative than to launch the product as a traditional food product, this can however create other problems because of the existing regulations on what can and cannot be mentioned in the marketing of a health food product. The limited amount of information about the product that can be enclosed together with it makes it hard for a company to differentiate and position it on the market.

The formation of sovereign states in regional blocks has become an essential feature in the world system. Therefore, the purpose of this paper is to investigate which motives and driving forces that affect the creation of projects of regional integration outside Europe and the Western World. By choosing the Latin American project of integration ALBA (the Bolivarian Alliance of the Americas) as a case of regional integration outside Europe and the Western World, the study investigates the motives expressed by the most prominent actors of the project, Venezuela and Cuba. ALBA is chosen as a representative and a unique case and through the consumption of the gramscian and the realist approaches, the essay defines two motives that affect the creation of projects of regional integration. As a way of investigating the actors? motives, the paper studies political statements, especially those of the Venezuelan president Hugo Chávez, and official positions expressed in central documents and declarations.

The purpose with this project is to explore and verify three renovating systems for Miljonprogrammet (common expression forbuildings constructed during the years 1965-1975 when over a million houses where built in Sweden) to take measure to thelargely transmission losses of these buildings. Many of the buildings from this period have similar constructions and thereforethe same techniques can be used to renovate several of them. This project only considers the climate scale, although thereare many more factors to concern for to efficient the buildings of Miljonprogrammet.This thesis presents examples of renovations carried out using two of the three renovation systems.The essay presents a reference house of choice on which we apply the three systems and calculate the new U-values,consumption of energy and the investment costs. The new U-values the building is given is matched to the values ofrecommendation for passive houses. Our reference house is a two story apartment building, located in the village ofLammhult, with brick facades at the ends and plaster at the long sides.
