Åkerinäringens inställning till biodiesel : en marknadsundersökning
In Sweden, there an increasing need for transport and this leads directly to fuel demand of the transport sector is expected to increase. Both politicians and industry believes that renewable fuels are a realistic and significant method to reduce the transport sector's environmental impact. This study aims to document the Swedish haulage contractor?s attitude to biodiesel. Also to document the strengths and weaknesses of biodiesel, based on opinions from the ultimate consumers.
Att uppnå varumärkesframgång genom dagens designtrender
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.
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.
IF Trions hemsida
Detta är rapporten för hur IF Trions hemsida kom till och utvecklades. Från det att iden kläcktes tills det att hemsidan var helt färdigställd. Arbetet bygger mycket på de olika säkerhetsbrister som en hemsida kan ha, till exempel hur lösenord ska hanteras. Med avseende på detta så ingår ett avsnitt i rapporten om de vanligaste säkerhetsproblem som man kan tänkas stöta på under uppbyggnadsfasen och exempel på hur man kan lösa dem. PHP är det programmeringsspråk som IF Trions hemsida är kodat med.
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.
Kampsport som verktyg inom socialt arbete
Studien söker svar kring hur undervisning i kampsport upplevs av vuxna kvinnor och om kampsportsträning kan ha en relevans för socialt arbete för kvinnor som målgrupp. Studien undersöker vilka val som gjorts av kvinnorna i samband med att de valde att börja träna kampsport och vilka upplevda effekter de har lagt märke att träningen leder till för deras egen del. Slutligen diskuteras vilka sociala verksamheter som kan tänkas ha nytta av kampsportsträning i sin verksamhet och vilka överväganden som då bör beaktas..
Cantralasiens strategiska betydelse:Den nye stora kampen mellan USA och Ryssland
The aim of this thesis is to assess the strategic importance of Central Asia as a whole and interests of great powers in the region in particular within the theoretical framework chosen. The work shows Central Asia as an area of the New Great Game, analogue of the original Great Game which was played out between the British Empire and Tsarist Russia in XIX century. The parallels between the original Great Game and the New Great Game are drawn in order to understand the scope and the true intentions of the players of the latter one. Also, the security issues in the contemporary Central Asia are explored and analyzed to provide with the background for future predictions. Furthermore, the indirect purpose of the thesis is to examine whether the international system has changed from that of two centuries ago by comparing the structure of the international systems at the time of two Games.
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).
Förslag till modell av kemikaliespridning i mark anpassad för användning vid räddningsinsats - Kemspill Mark 4.0
After emergencies involving chemical spills it is of great importance that correct measures are taken with short notice, both for the security of people and in order to minimize future environmental consequences. The RIB-unit at the Swedish Rescue Services Agency initiated this study, the aim of which is to propose changes to the existing chemical transport calculation tool: Chemical Spill 3.4, included in RIB - Integrated Decision Support for Civil Protection, so that it can be used for decision support as well as in preventive work. A rough estimation of chemical transport in the subsurface is considered being of great importance when making decisions during emergency response operations.The proposition presented in this report is a non site specific chemical transport model which is designed to give a rough estimation of NAPL flow in homogenous isotropic soil shortly after an instantaneous release. The model can be used at two levels; both in situations without access to information on subsurface properties, and with more accuracy in situations with knowledge of the included parameters. For that reason the user can choose among predefined alternatives or assign the parameters a numeric value to increase the quality of the model output.
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.
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.
