Beslut om betydande miljöpåverkan för järnvägsprojekt : beslutsmotiveringar, åtgärder och regionala skillnader

This thesis examines the reasons to why railway projects conducted by Banverket (Swedish National Rail Administration) could be expected to cause significant effects on the environment, on which grounds the County Administrative Board and Swedish National Rail Administration base their decisions/assumptions and highlight regional differences between the different Swedish national rail administrations regions. Total 24 railway projects, conducted or being conducted, during the time period 2001 - January 2010 have been analyzed and studied. These projects represent eight different measures/activities which are dispersed throughout all five of the Swedish National Rail Administration´s different regions. Swedish legislations demands that the planner of a new railway project shall first conduct a pre-study and then conduct a public consultation which provides the participants an opportunity to provide input. The County Administrative Board shall then decide if the project could cause significant effects on the environment.

Increased growth in Norway spruce (Picea abies (L.) Karst.) through small annual additions of nitrogen (N) fertilizer

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

Avfallshantering på byggarbetsplatser : Potential för en miljöeffektiv avfallshantering

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

Entrepreneurs subjective well-being and job satisfaction: does personality matter?

Previous research has suggested that there is a strong and positive relationship between being an entrepreneur and possessing a high degree of subjective well-being as well as job satisfaction. The big five personality traits have also been argued to be significantly related to both subjective well-being and job satisfaction. Little is however known if personality affects entrepreneurs and regular employees differently. In this paper the impact of personality traits on the cognitive part of subjective well-being as well as job satisfaction are investigated separately among entrepreneurs and regular employees. This is done through OLS-regressions using a Swedish nationally representative survey Employment, Material Resources, and Political Preferences (EMRAPP), where entrepreneurs were oversampled in order to be able to compare entrepreneurs (N = 2483) and regular employees (N = 2642).

1-D Modellering av Piezoelektrisk Injektor

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Påverkar olika faktorer bilföretagen? : ? Hur påverkar ett högt oljepris, miljömedvetna marknader och ekonomiska trender bilföretagen?

The automotive industry is today in a world of globalisation and external factors can influence the car companies and it is important that they progress with the people. When an external factor, as the oil price, increases dramatically, it will affect the economies in different matters. Other external factors are impacted by the oil price, for example inflation, unemployment and target rates. In addition, people are changing their preferences due to the attention of the environment. With this as the foundation the problem of the essay were divided into three aspects.

Naturvärden i Killingeskogen : Biologisk mångfald och friluftsliv

Killingen is an area situated on an island called Resarö in the municipality of Vaxholm. The areais covered with forests with a varied topography and a mosaic of environments. The municipalitywants to keep the area unexploited, for recreational purposes but what are the natural values inthe forests? The survey concluded that a mosaic of nature types had high values and could behosts for vulnerable species.As part of the study, measures that will improve the quality of the paths and bathing areas for thelocal population was proposed as well as means to heighten or preserve the natural values in thearea..

Gammal och förvirrad : Sjuksköterskans omvårdnadsåtgärder vid konfusion hos äldre

Konfusion är mycket vanligt förekommande hos äldre och skapar stort lidande, ger höga samhällskostnader och orsakar hög mortalitet. Syftet med studien var att belysa sjuksköterskans icke farmakologiska omvårdnadsåtgärder vid konfusion hos äldre patienter. Metoden var en litteraturstudie, vilken innefattade tio artiklar där relevanta omvårdnadsåtgärder framkom, dessa presenterades i resultatet under VIPS - modellens åtgärdssökord. Resultatet av studien visade att patienter med konfusion mindes och uppmärksammade vad som skedde med och runt omkring dem. Viktigt var att få information om sitt konfusionstillstånd för att förstå vad som hände och varför.

Politiska visioner och regionala krafters inverkan på kulturarv : En studie om hur Kalmar läns kulturarv används och värderas i det postindustriella samhället

This is a qualitative essay that has its starting point in the deindustrialized community in the county of Kalmar. At the time deindustrialization started, the globalization and the technical development took form, this resulted in increasing traveling in the world. The communities that had lost their industries had to find new ways of surviving. The politicians used the increasing travelling and tourism and saw a new industry in the tourism, therefore they made cultural heritage visible. Main focus lies in the will from politicians to visualize cultural heritage for economic gain and the administration of cultural heritage that in essence had to accept a new use of the cultural heritage.

Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg

In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.

En jämförelse av RDF och avfall som förbränningsbränsle

In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.

Studenters riskuppfattning och beredskap i hemmet : En kvalitativ studie om kopplingen mellan riskuppfattning och beredskap i hemmet

The focus of this thesis is on what is considered to be a suitable foster home. For the study to be carried out an application had to be made to get access to the foster home assessments in a medium-sized municipality in Sweden. With the support of attachment theory and theory of standards different categories have been picked out and analyzed in foster home assessements that have been approved. The conclusion to what is considered to be a suitable foster home is a complex issue, as there are many factors that are interacting. Social workers seem to focus on the importance of a family?s ability to provide some kind of stability and security for a child who is considered to be placed within their home.

The shift in forest and tree limits in Troms County - with a main focus on temperature and herbivores

To better understand how various factors affect the establishment of forest and trees around the tree line-ecotone, this study was conducted in Troms County, Norway. The altitude of different forest and tree limits together with the surrounding vegetation type were collected during August 2011. Comparisons of the collected data were made with previously collected data from the same sites conducted 1914 and 1915. On average the forest limit has expanded with 26 meters in altitude, however, an expansion is not statistically significant for the whole area. The tree limit has significantly expanded in altitude.

Kunskaper om karies och gingivit hos barni årskurs 3-5 - en enkätstudieKnowledge of caries and gingivitis among third to fifth grade school children

The aim of this study was to investigate the knowledge of caries and gingivitis among third to fifth grade school children. A questionnaire was distributed to 117 children of a primary school in the south of Sweden. The result of the study indicate that the children had good knowledge regarding development and prevention of caries and gingivitis. However, the children did not know the meaning of the words caries and gingivitis. The children also appeared to lack important information about dietary measures to achieve good dental health.

Två synsätt på elevers lärande av ämnet statistik : En studie av elever i årskurs 7

The purpose of this paper is to create increased understanding of how pupils learn statistics. This includes gaining insight into pupils' use of their own experience and group experience to help to get a better understanding of statistical problem solving. The study's research questions are about how pupils learn to work with data in tables and diagram and how pupils learn to work with measures.The theoretical framework consists of two approaches to studying learning. One approach is based on pupils? cognitive conditions, called set-befores, and the pupils' previous experiences, called met-befores.
