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.
Ekologiska livsmedel i offentlig måltidsverksamhet
In our everyday life we are faced with many choices that have consequences on the environment. One of these is the food we choose to eat since food production has a big impact on the environment. In organic production the aim is to have a natural production process, where environmental impacts are minimized. By choosing organic food it is therefore possible to contribute to a better environment. A large number of meals are served every day in the public sector, which makes it an important player in the consumer sector that could make a major difference for the environment..
Kadmium i skånska vattendrag : en metodstudie i föroreningsmodellering
Modelling of pollutants is commonly used in research and at departments working with environmental issues. The need to use large amounts of data when modelling creates the opportunity for more generalised models with lower data demands. Aggregating functions into coarser elements is a sort of generalisation of actual features in nature.A development of a method and a modelling tool called ?KadmiumKalkylatorn? has been performed to model cadmium pollution in rivers in Skåne, Sweden. The water runoff has been multiplied with cadmium standard concentrations based on membership in landuse classes.
Metoder för att beskriva kumulativa effekter med avseende på biologisk mångfald och vägar :
Cumulative effects are seldom treated in Swedish Environmental Impact Assessments (EIA). This report treats these questions and which procedures and methods that can be used when assessing cumulative effects in EIA.
This report is a literature study where also a case study is a part. The case study shows how existing methods for cumulative effects can be used in practice. The report is concentrated on biology and treats cumulative effects on premises of biodiversity and roads.
Cumulative effects include both direct and indirect effects.
Smärtbedömning ur ett sjuksköterskeperspektiv
Background: To wait on an emergency department is a reflected and well-documented problem. Thou it´s mainly due to a patient perspective should also nurses' perspectives be significant to obtain a faceted perception of the phenomenon.Aim: The purpose of this study was to describe how nurses perceive the phenomenon of anticipation of a somatic emergency department.Method: The analysis was performed using a phenomenological approach. The study was conducted in a medium-sized hospital in southern Sweden, during the latter part of 2005, and had a qualitative approach based on a lifeworld perspective. Data collection consisted of written stories from twelve nurses.Results: The results indicated that the waiting was the scene of the expectations. These expectations led to dilemmas, powerlessness and frustration, the more the phenomenon was allowed to stand.
Vittnens behov av stöd
Syftet med denna studie var att undersöka om vittnen till brott mot person i Örebro län är i behov av stöd innan rättegången. Frågeställningarna som användes var: är vittnen till brott mot person i Örebro län i behov av stöd? Vilken typ av stöd vill dessa vittnen ha? Vilka möjligheter och svårigheter finns för Brottsofferjouren att komma i kontakt med vittnen som är i behov av stöd? Till studien användes en kvalitativ metod bestående av individuella intervjuer och fokusgruppsinspirerade gruppintervjuer med vittnen och vittnesstödjare. Resultatet visade att vittnena är i behov av stöd då det finns en rädsla för repressalier samt en osäkerhet för hur rättsprocessen går till. Stödet som önskas är information om vart stöd finns att få samt vad som händer i rättsprocessen.
Glöm inte barnteatern! En studie om barnteater på folkbiblioteket.
This master?s thesis deals with the issue of children?s theatre at the public library. I want to examine what purpose children?s theatre play for the children according to the children?s librarians, what different factors that may influence the purchase of plays to the public library and what the children?s librarians think of the children?s theatre at the public library at present and in the future. Interviews have been conducted with four children?s librarians, at different libraries, who are somehow involved in the purchase of children?s plays to the library.

Värderingar, ansvar och affärer : En fallstudie om hur Löfbergs Lilas värderingar påverkar företagets CSR-arbete och affärer
AbstractThis master thesis is a hermeneutic inspired case study of how the value base regarding the environmental and social responsibility in the Swedish coffee company Löfbergs Lila AB is affecting the company's business. A thesis inspired by hermeneutics means that it is based on two ideas, the one of interaction between entirety and partitions and the one of interpretation (Alvesson & Sköldberg 1994). This cause that the emphasis is on how the reality is interpreted and that it never can be seen as completely objective.The case study was conducted during the spring semester of 2010 at Karlstad's University and consists of both empirical and theoretical material collected during this time. The empirical material in this thesis includes, among other things, interviews with four representatives of Löfbergs Lila AB, written material from the company regarding its work related to Corporate Social Responsibility (CSR), some information about the coffee industry as a whole and different certifications for "ethical? coffee that exists on the Swedish market.The basic idea with CSR as a business strategy is that it can be financially beneficial for companies to take a social and environmental responsibility outside of the company (Vogel 2005).
Miljö som konkurrensmedel: intervjuer med fem småföretag och två revisorer
Det växande intresset för miljöfrågor har ökat kraven på företagen. Intressenterna kräver att företagen kan hantera miljöfrågorna på ett tillfredsställande sätt. Att införa ett miljöledningssystem är ett sätt att arbeta med miljöfrågorna. För att kommunicera ut miljöarbetet används företagets miljöredovisning. Under 1990-talet har intresset för miljöredovisning ökat kraftigt men är i mångt och mycket fortfarande ett storföretagsfenomen.
Människan i naturen : om etiska gränsdragningar och djupekologins kritik av antropocentriska naturuppfattningar
The subject-matter of the following essay is to investigate the relationship between what is commonly called Deep Ecology or Biocentric Philosophy, as articulated by the co-founder of the Deep Ecology Movement, Arne Naess, and later proponents of the biocentric school of environmentalist thought. I contrast Naess? concept of Self-realization as founded in his Ecosophy T to the ideas of american conservationist and co-founder of the radical green movement Earth First! Dave Foreman, and to the controversial finnish environmentalist and ecofascist Pentti Linkola?s ideological agenda of population-reduction respectively.According to some critics of the movement, especially the social ecologist Murray Bookchin and French liberal philosopher Luc Ferry, the Deep Ecology ideology is essentially misanthropic and totalitarian in structure. A central idea among deep ecologists is that ecosystems and natural entities have intrinsic value in themselves, even outside a human social context. This idea is thought of among deep ecologists to create a philosophically sound basis for counteracting the environmental global crisis.
HRM-konsulters arbete mot SME-företag : En studie kring HRM-konsulters affärmöjligheter i SME-företag
Human Resource Management (HRM) consultants are becoming more common. Simultaneously there is a lack of HRM in small and medium enterprises (SME?s). SME?s states neither to afford, nor have the time to perform HRM in their business.This thesis is a Working Scholarly essay based on qualitative method, based on ten semi- structured interviews.
Avskogningen av Amazonas
Organic agriculture is financially promoted in Sweden by special environmental support and as consumers we are all encouraged to buy organic food. At the same time scholars at the Swedish University of Agricultural Sciences claim that organic farming does not provide any environmental benefits. The main criticism is that organic farming has lower yields than conventional, which means that more land is needed to produce the same amount of food as in conventional farming, leading to deforestation and loss of biodiversity. As for climate change, the critics claim that the significantly higher productivity in conventional crop production compared to organic, releases surplus land, which could be used for bio-fuel production and thereby replace the fossil fuels. The critics also claim that organic farming causes higher nutrient leaching than conventional.
Challenges and incentives for sustainable manure management in Russia
The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years.
A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed.
The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably.
The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.
Energismart modulhus med takintegrerade solceller
The purpose of this thesis is to examine how investments are justified in the Swedish data center industry, with a focus on cooling equipment. This is achieved through semi-structured interviews with 20 different interviewees. These interviewees represent different facets of the industry and facilitate an understanding of which factors, such as: investment costs, operating costs, reliability, environmental impact and the influence of external and internal actors, come into play and to which degree they impact the investment decision-making process. The results show that primarily low operating cost in the form of low energy consumption is the driving factor when it comes to the procurement of new equipment. A lower environmental impact is a positive side-effect of lower energy consumption.
