Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris). Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.

Industrins energianvändning medför koldioxidutsläpp som bidrar till klimatförändringar. Inom EU och Sverige eftersträvas en konkurrenskraftig industri. För att uppnå båda delarna förespråkas det att företag energieffektiviserar och minskar sin energianvändning. Trots att energieffektivisering ofta är kostnadseffektivt existerar det ändå ett energieffektiviseringsgap där kostnadseffektiva åtgärder inte implementeras av olika anledningar. Energinätverk kan då vara ett potentiellt arbetssätt som medför energieffektivisering och bidrar till företagsutveckling.

Hemp is an old agricultural plant and has been used for hundreds of years for making textiles, ropes and other fibre products. In the middle of the last century the Swedish government prohibited all growing of hemp. Natural fibres were replaced by syntetic fibres instead. Today there is a newly awakened interest for using natural fibres from renewable materials. Growing of industrial hemp for fiber is allowed in Sweden again. I want in my Paper give Swedish growers an insight of which harvesting methods that have been tried in Sweden and how they worked.

During the last decade a number of studies have been published that investigate how the most fundamental aspect of political organization, the regime type, affects population health. The results unanimously show that citizens of democracies live longer and healthier lives than citizens of non-democracies. Many explanations for this have been suggested, among these are that democracies redistribute more and invest more in salutogenic resources, and that the tendency of dictatorships to control the media negatively affects the ability to spread information crucial to public health. When these mechanisms are controlled for, however, it turns out that democracy has a large residual correlation with for example life expectancy, which suggests that other mechanisms are also involved.In this paper two new mechanisms regarding the possible psychosocially mediated health effects of the regime type are investigated, namely political repression, and the possible negative effects this might have on the levels of chronic stress, and autonomy, which connects to a large previous literature in social epidemiology. In the paper an ecological cross-country design is used and country-level data, provided mainly by the World Bank and Freedom House, is analyzed with a simple multiple OLS-regression model.

The first official Islamic bank was established in 1975. The characteristic of an Islamic bank is that the bank is based on an interest free system. The interest free system is a requirement for an Islamic bank. The Islamic bank system is based on Sharia laws which are laws that are followed by Muslims and it is based on the text from the Quran. The Islamic Banks had a rapid expansion between 1993 and 2003, the expansion was about 23 percent and since 2003 have the expansion been about 20 percent.

Abstract This study aims with a pragmatic approach to investigate the learning about how to solve simple equations, and what the teacher can do to help the student. Four questions asked are: (i) How and why will learning take place? (ii) What will complicate learning? (iii) How to support and facilitate learning? (iv) Is it possible to identify an influence between identity and learning? To answer these questions a qualitative study in elementary school is done. The results of the investigation are compared with previous research, and an interview with the teacher is presented. The recorded lessons are analyzed with PEA (practical epistemology analysis), and letters from the students with the Ecological Systems Theory of Bronfenbrenner.

Många små- och medelstora företag har idag en hemsida. För att en hemsida skall vara ett effektivt kommunikationsmedium med kunder krävs dock att den är uppdaterad. Vi anser att många företag ej förutser vilka resurser som krävs för att hålla sidan uppdaterad. Vi vill därför kartlägga vilka problem företag i dagsläget upplever att de har med sitt uppdateringsarbete. Vi vill därefter se om det finns en möjlig lösning i verktyget Smelink WEB ifrån Smelink AB, som säger sig underlätta webbnärvaron för denna typ av företag. För att undersöka ovanstående frågeställning har vi valt att gå ut med en enkätundersökning rörande hur uppdateringsarbetet går till i två grupper av företag. Den ena företagsgruppen använder sig utav Smelinks verktyg och i den andra företagsgruppen vet vi ej hur uppdateringsarbetet går till. Då vi sammanställt resultatet kunde vi konstatera att det ej fanns några omfattande problem rörande uppdateringsarbetet hos de företag som vi undersökt.

Hemmasittare is a new term for children and youths with a history of long term truancy. As the term indicates these youths spend most of their time in their homes. This often results in them being socially alienated and the loss of their earlier social network. The consequences of hemmasittande and social alienation are many and include not only a deficient social network but also psychological and physical problems. Research has shown that many of these problems follow on through into adult life.

The possibility for plants to utilize phosphorus in soil is a prerequisite for conducting agricultural production, both small scale and professional. Spreading of phosphorus fertilizers and manure is therefore seen as a necessity in today's agriculture in order to achieve high yield. Manure management, livestock farming and manure storage could contribute to the eutrophication of lakes and rivers. For instance, when the ground becomes saturated, phosphorus leakage could be seen in surface runoff or in point sources resulting from inadequate manure storage management.In the municipality of Växjö there is still many bodies of water that do not reach the Swedish environmental water quality standard of "good ecological status". This thesis has therefore analyzed the manure management and storage on agricultural farms which may have contributed to eutrophication in the municipality.The method for this thesis was a literature study, a questionnaire survey with 820 receivers and a summary of issued inspection reports from 2013.The results highlight the ways in which agriculture may have contributed to the eutrophication of lakes and streams in the municipality of Växjö.

The purpose of this essay is to explore the actor network of a high technology company in the textile industry called F.O.V. Fabrics. The background for doing this is a recent project, which we choose to call the Salt & Paper Battery Group, aiming to commercialize a newly discovered technology ? a battery based on cellulose from an alga. We start by examining a range of network theories in order to eventually shape a framework of our own.

The purpose of our study has been to analyze the character of the interaction between music labels and media and to examine to what extent the artist brand is being considered in music labels relationship with media. This has resulted in our research question:What characterizes the large music labels relationship with media?For this study we have used a qualitative approach to achieve a deeper understanding of our chosen topic. We have conducted seven interviews with representatives from both major record labels and media companies with great knowledge about our subject. Five of the interviews were conducted face-to-face and two were performed via e-mail.In the final chapter we answer our research question and thus present our conclusions.

Local participation in nature conservation has gained more attention over the last decades due to international conventions as well as local and national initiatives. This development can be seen as a reaction to a more expert oriented nature conservation characterized by centralized control and strict preservation of so called "original" nature. The overall objective of this thesis is to contribute to research on new forms of conservation where democracy and local participation is included. The case study focuses on the process of producing a pre-study for a suggested national park in southern Jämtland in the Swedish mountain region, and aims to investigate to what extent local participation was included. The pre-study was led by the Swedish Environmental Protection Agency (SEPA) and the County Administrative Board (CAB) in Jämtland.

Family centres are established to serve families with children and the personnel usually consists of units of social-workers, preschool staff, paediatric nurses and midwives. The purpose of the study was to examine the social-workers preventive work with families at the family centre. To fulfil the purpose, a qualitative interview with five social-workers was conducted. The theoretical framework referred to attachment and empowerment theory. The results of the study showed that the main part of the work consists of giving advice and support to parents.

Narkotika- och alkoholmissbruk är ett hälsoproblem i hela världen och nyktra missbrukare är en utsatt grupp i samhället. Vid missbruk är det inte bara intaget av narkotikan eller alkoholen som medför skada. Hela livssituationen kan bli drabbad, inte minst kontakten med vänner och familj. För att hålla sig nykter, återanpassa sig till samhället och leva ett hälsosamt liv finns det många faktorer som är betydelsefulla. Syftet med studien var därför att undersöka nyktra missbrukares upplevelser av socialt stöd, fritidsaktiviteter samt utanförskap och delaktighet i samhället.

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.
