An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

The aim of this thesis is to examine the existence and prevalence of earnings management in Swedish companies. Theoretical frameworks often suggest that there are strong incentives to practice earnings management. The research area of earnings management has, to date, mainly focused on detecting earnings management. However, to our knowledge, no such studies have been conducted on Swedish companies. This thesis provides evidence of the existence and prevalence of earnings management in Swedish companies.

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

Community Supported Agriculture (CSA) is an unconventional model of agriculture expected to contribute to a more sustainable food supply and a sustainable landscape; the development of rural areas; a stronger relationship between producer and consumer and a healthier diet. This study, with a focus on food production and the link between the producer and consumer, describes the origin and current development of CSA in Sweden, including the prerequisites for CSA in a Swedish context. Organizations and entrepreneurs working with CSA and related projects are identified and interviewed. The notion of CSA in Sweden is still in its infancy, but a rapidly growing interest currently can be detected. The fact that the identified CSAs are found in different Swedish regions with variations in degree of urbanization and intensity of agriculture indicates that the prerequisites are there for the concept to grow, both in rural as well as urban areas.

Uppsatsen är baserad på en fallstudie gjord på Tetra Pak. Syftet med fallstudien var att utforma en lista med faktorer att som bör beaktas för att ett införande av ett Competence Management-system ska bli framgångsrikt. Tillvägagångssättet i fallstudien har varit en dokumentstudie och ett antal intervjuer. Använda teorier är hämtade från områdena Change Management, Knowledge Management, Competence Management och Human Resource Management. Undersökning resulterade i ett antal intressanta faktorer som bör beaktas.

Syftet med uppsatsen är att undersöka frekvensen av krisstrategier inom livsmedelsbranschen och hur pass sofistikerade dessa strategier är. Vidare vill vi se närmare på en del av de moment som crisis management-teorierna behandlar. Förekomsten av krisstrategier är stor, men endast ett fåtal av företagens strategier uppfyller våra kriterier för att anses såsom mycket sofistikerade. Företagen anser själva att det är viktigt med crisis management, medan de i verkligheten inte i lika hög utsträckning har de element som författarna till den crisis management-teori, vi använt oss utav, menar ska finnas med. Företag som varit i en kris har mer sofistikerade krisstrategier än de som inte har upplevt en kris under de senaste 20 åren..

Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.

There are many different recommendations on how to keep pelargoniums over winter, but most of the recommendations suggest ?the higher the temperature, the more light and water the pelargonium needs?. The purpose with this paper is to try to explain the best and the worst results that are achieved with different storage alternatives of zonal pelargoniums. The results are based on an orientating investigation carried out in January-February, and a questionnaire that members of the Swedish Pelargonium Society answered to. Both the orientating investigation and the questionnaire showed that zonal pelargoniums are best stored light and cold but frost free. They should be irrigated according to their needs which is when the soil is dry, about every second to third week. Zonal pelargoniums are very resistant to drought and can survive without water for at least 44 days, both when kept under light and cold as well as under light and warm.

Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.

The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines. This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments. The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done. The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..

This report that is written in cooperation with Peab Sverige AB, studies the information and knowledge management from the production support to the production management. The conclusion of this report is that to have a good and functional information and knowledge management it is necessary that the company has a good way of regain and handling experiences from its projects. The way to do this is to develop the managing system on the production management?s terms. It is also critical to find an easy way for the production management to use the system..
