Utlakning av tungmetaller från Skörby deponi

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.

Chefskontrakt : ger det en tydligare anställningsform för chefer i Landstinget Västmanland?

The purpose of this work is to find out how present manager contracts are set up in Landstinget Västmanland (the county council of Västmanland), explore managers? perception of these contracts and why managers have chosen leadership. The work has also reviewed the question if managers need to have a relationship or expertise to the activities they lead and which qualifications are needed in such case. The survey was conducted in two divisions in which nine interviews were held with managers at all levels. In addition to this a questionnaire including the 87 managers in the divisions were held.

Dimensionering av industrilager för biobränsle :

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).

Gestaltningsförslag för Norbyvreten : från kvarterspark till stadsdelspark

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.

Analys av framtida potential för virkesköp från privata skogsägare i Västerbottens län : beslutsunderlag för virkesköpsstrategier

This study was conducted on behalf of SCA forest AB, Västerbottens forest administration. Timber procurement from non-industrial private forest owners has become an increasingly important part of SCA:s wood supply. The objectives of this study was to report the current forest conditions in the private forests in the county of Västerbotten, analyse the potential for procurement of wood from private forest owners, and provide a basis for decisions on future strategies for timber procurement from private owners.Material and data have been collected from different sources, mainly from Swedish National Forest Inventory and SKA-VB08. This material was the basis for the analysis and calculations performed with the Heureka application PlanWise. This study area was divided into six different analytical areas (Coastal south, Coastal middle, Lycksele, Inland south, Inland north, Skellefteå), where each area of analysis is represented by a number of municipalities.In this study, two scenarios were specified; one describing the current forest management with current harvesting levels and the effects of these assumptions, the second to illuminate what potential there is for future timber harvesting.

Tysta regleringar i kollektivavtal

The collective agreement contains many important provisions concerning the relationship between employers and employees. When a collective agreement applies in the workplace, both employers and employees are bound by it. However, only employers of those two, can take part in the collective agreement, and therefore negotiate the content of it.The purpose of this study is to answer the following question: Why are rules that has been interpreted in collective agreements not expressed in writing? Therefore, the Swedish collective agreement system will be examined, and a distinction between types of silent regulations will be made to find causes. The potential for workers to act on a collective agreement with quiet regulations will also be examined.Collective agreements are signed on three levels: central, union and local levels.

Energideklaration- Vad är det och hur ska det hanteras i fastighetsbranschen?

AbstractThe Energy Declaration is a law that will come into effect October 1: Th 2006. This report has Värnamo municipality as principal and shall clarify what the estate owner in general and Värnamo municipality in particular need to know about this law. Another part that is going to be dealt with is how large the future need for energy experts in this field will be, and which competence that will be demanded for them.The work will in general deal with simplified energy declarations for apartment houses and public buildings, since these buildings are the first to be involved with energy declarations.The energy declaration will consist of a number of important components.? Energy power i.e. how much energy the building consume? If the ventilation control is done? If the radon measurement is carried out? Recommendations of measures to improve the energy power? Reference value to compare the buildings energy power againstAccording to the law the declaration shall been made by an independent expert, which will need certain information for this.

Nedskrivningsprövning av goodwill: En studie av regler som någon hittat på för en tillgång som inte riktigt finns

Since January 1 2005 all companies listed on a regulated stock exchange within the EU are required to present their consolidated accounts in conformity with IFRS. Among many other consequences goodwill will no longer be amortized over its useful life but instead annually tested for impairments in accordance with IFRS 3. The aim of this paper is to scrutinize the impairment test of goodwill as outlined in IAS 36 and analyze its implications. We conclude that the impairment test will probably lead to the recognition of internally generated goodwill in the consolidated accounts. We also conclude that the impairment test on highly aggregated levels will probably hasten the pace of this recognition since internally generated goodwill is used to shield acquired goodwill from impairments.

Djurägare och djurhälsopersonals upplevelse av djurägarcompliance vid tandvårdsråd - likheter, skillnader och möjliga lösningar

The extent by which pet owners follow health care instructions falls within the confines of ?compliance?. The success of any given treatment is in part due to the way in which the owner complies with the instructions received from the advising veterinary professional. Studies abroad have found that the preventative dental care sphere suffers from a low compliance rate. Together with the fact that veterinary staff commonly issue advice on preventative dental care, this provided the impetus for undertaking the current research.

Immunisering för att minska ornelukt

Hundreds of thousands of piglets are castrated without anesthesia in Sweden every year so that we may be guaranteed meat without boar odor. The smell appears while cooking meat of boar and is described as urine- and sweat-like. High levels of androstenone and skatole are considered the main factors behind boar odor. Skatole is a metabolite of the amino acid tryptophan, which is formed in the colon of all pigs. Androstenone is a steroid hormone that is released from the Leydig cells in the testes of boars.

Morgondagens effektiva fjärrvärme : En beskrivande litteraturstudie

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.

Vägen till framgång : hur kommuner använder sig av livsstilsmarknadsföring och platsmarknadsföring som differentieringsmetoder

The purpose of this essay is to examine how the two Swedish municipalities, Sigtuna and Nyköping, work with marketing. The study has primarily focused on how these two municipalities worked, consciously or non-consciously, with lifestyle marketing and place marketing. The research-questions that this essay wants to answer are;What is lifestyle marketing and place marketing?Do municipalities use these types of marketing, and who is this marketing directed to?How and why does municipalities use lifestyle marketing and place marketing?To answer these questions, phone interviews were conducted with several important employees within the two municipalities. The results of this study show that the different municipalities have both been using lifestyle marketing, but on different levels, in Sigtuna, it was a strategic choice, whereas in Nyköping, it evolved by itself and was not a conscious choice.

Vardagsmat eller domedag? Marknadsföring av ekologiska varor genom svaga och starka rädslor

In a time when concern for the environment is a topic that is met with both love and hatred, organic goods and services become increasingly common on the market. Communication efforts with the purpose of increasing the proportion of organic products consumed are being conducted by both private and public actors. However, achieving attitudinal and behavioral change within complex areas such as this comes with many difficulties.Within public opinion change, a common way of achieving a change in behavior is to use fear appeals and scare tactics. Earlier studies have shown that messages prompting a low level of fear can be more effective than messages prompting a high level of fear, since a high level of fear tends to raise defense mechanisms in the consumer. The purpose of this essay is to examine whether fear and defense mechanisms is a problem when it comes to making consumers choose organic products, as well as studying whether messages prompting low levels of fear are more effective than those prompting high levels of fear.This quantitative study is conducted in the form of a questionnaire-based experiment, comparing the effectiveness of two messages prompting different levels of fear.
