Ethanol for Scania's Future - A Scenario Based Analysis
Abstract Title: Ethanol for Scania?s future ? A scenario based analysis Authors: Anna Hansson and Julia Persson Tutors: Annette Cerne ? Department of Business Administration, Lund University Jonas Holmborn ? Head of Advanced Combustion, Engine Development, Scania Lennart Thörnqvist ? Department of Energy Sciences, Faculty of Engineering, Lund University Problem: Oil-based products are the dominating fuels in the transport sector but alternative fuels are currently challenging the world-wide dominance. The large number of alternative fuels that are under development at present makes the future fuel-market impossible to predict. Scania?s ethanol project is associated with a number of uncertainty factors that are beyond the company?s control.
Hårvårdsverksamheter ur ett miljö- och hälsoskyddsperspektiv : Kartläggning av frisörer i Danderyd och Vaxholm och utarbetande av checklista för inspektioner
Hair care is a hygienic treatment and is supervised by the Local Environment and Public Health Committee in the municipality. According to the Swedish Environmental Code, hairdressers as all practitioners are required to take measurements to protect the environment and public health. In hygienic treatments hazards may arise from inadequate hygiene practice which spread infection. Hazards may also arise from the use of hair care products such as permanent wave solutions, bleaches and hair dyes. Some hair dye components are known to cause contact allergy, mostly in hair dressers who are exposed professionally but also in some cases in consumers.

Inramning av klimatförändringar : I svensk dagspress 2012 och bland unga vuxna
Something that all people have come across and more or less experienced is climate change. Climate change in itself is a very complex problem since there are no borders between countries that can stop the problem. The link between science and the public is largely in the hands of the media, since the media play an important role in defining environmental issues and to inform the public about research findings. In recent years, reports from the media showed a slightly skeptical and uncertain picture of this problem. This is despite the largely prevailing consensus among climate scientists that there is an anthropogenic climate change.

Tekniken kring mobiltelefoni är under ständig utveckling och mobiltelefonen har idag fått nya funktioner utöver dess grundfunktion röstsamtal. Efterfrågan efter nya mobila tjänster drivs hela tiden framåt då mobilen får allt större kapacitet och prestanda. Bland de tjänster som växts fram märks möjligheten att utföra monetära transaktioner. Detta innebär helt enkelt att använda sin mobiltelefon för att betala och utföra allehanda tjänster kopplade till användarens monetära tillgångar. Överföringen av pengar kräver dock hög säkerhet.
Klotter och skadegörelse på en högstadieskola: en miljöpsykologisk fallstudie med fokus på fysisk miljö.
The purpose of this study was to examine and try to understand the physical environment focusing on the fenomena of scribble and damage at a high school. More specifically its aim was to find out how the pupils themselves discribe their physical environment, the reasons why there are scribble and damage at their school and how they are treated by the adults at the school bearing in mind the scribble and damage that occur. The study took place at one high-school in the southern of Sweden and the methods used were six qualitative interviewes, a minor inquiry in six classes, fotographing the physical environment and putting up scribble boards on the pupils' toilets. The physcial environment was quite bare and monoton and the pupils often felt bored by it. There were few places where the pupils liked being at.
Perceptions of domestic solar systems : a study on non-adopter views of a new technology
The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany.
The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.
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.
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.
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..

Slutligen diskuteras vilka sociala verksamheter som kan tänkas ha nytta av kampsportsträning i sin verksamhet och vilka överväganden som då bör beaktas..
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.
