Hantering av bränsleflis : Enkätundersökning och bedömning av kvalitetsaspekter

Med globalt ökat klimathot och ett ökat användande av biologiskt nedbrytbara material för att bland annat driva vår motorpark och värma våra hus kommer även ett krav på ökat produktion av utsläppsreducerande (koldioxid CO2) material så som biobränsle.För att kunna reducera utsläppen krävs inte bara att vi ökar produktionen av biologiskt nedbrytbart ämnen utan att dessa material har de egenskaperna som de förbränningssystem de används till optimalt kräver.Ett av de biologiskt nedbrytbara materialen är biobränsle, framställt av skogsavfall (grot). Dess hantering ifrån avverkningstillfället tills in- transport till förbränningen har varit kärnan i detta arbete. De två grundfrågorna som har varit själva motorn i arbetet har kretsat kring;o Vem äger vad i olika hanteringssteg?o Vem vet vad i olika hanteringssteg?Syftet med denna undersökning var att bland annat försöka få reda på svaren på frågorna ovan men även att väcka ett ökat intresse och förståelse kring hanteringen av biobränslet från avverkningstillfället fram till in- transport till en terminal alternativt direkt in till panncentralen.Undersökningen gjordes genom en enkätundersökning på Internet. Enkäten skickades ut till berörda parter i Sverige per e-post och adressaterna kunde svara direkt i datorn och skicka tillbaka enkäten utan att skriva ut den.

Ämnestransport med grundvatten i hydrogeologiska typmiljöer

Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.

"Det går inte att badda in elever helt" : - om lärares möjlighet att påverka förekomsten av självutlämnande elevtexter.

Several researches asserts that as teachers are responsible for the content of teaching and by formulating teaching "Why, ""How" and "What", that will also give signals to students about what is important knowledge. This essay addresses the difficulties teachers may face in terms of self-disclosure student texts and awareness of this in the design of teaching and writing tasks. Research shows that self-disclosure and self-therapy student texts exist and that teachers are experiencing a difficulty with regard to assessment and treatment.Through qualitative interviews examined seven teachers' design of any, to the student, self-disclosure information from curriculum and policy documents. Another purpose of this paper is to examine the extent to which teachers, through the information they give to their pupils, may affect the texts students submit. It turns out that the respondents are united in the belief that they, through their data, may affect the texts they receive from their students when they are the ones that control the content of teaching, and they agree that the curricula gives them a great choice for design data. The survey shows that the perception of the curriculum that will open up for self-disclosure texts differ as some of the respondents believe that the curriculum is very much about the students way to express feelings and opinions, while others believe that they may try to package this data in another purpose or exercise.

Stabil växelkurs och låg inflation - Inbördes oförenliga? En studie av implikationerna av en real appreciering

This paper examines a long run macroeconomic dilemma. This dilemma states that given a real appreciation, i.e. a continuous increase in the real exchange rate, an economy has two options open with respect to inflation and nominal exchange rate. Either the economy chooses a fixed exchange rate- regime but has to allow for a rising inflation. Or the economy can choose an inflation targeting- regime, but then has to allow for an appreciating nominal exchange rate.

Marknadsföring via sociala medier : Social Media Marketing

The thesis work focuses on marketing and its point of departure centers on mapping the utilization of social media as a form of marketing. The choice of this thesis subject has been deemed by the authors as one of particular interest due to the current popularity of social media in the Internet connected society and their use as marketing tools. Specifically, this thesis sets out to explore how companies exploit social media tools in marketing and how their use affects retail operations and customer relations in an effective and creative way.The report concentrates on qualitative data collection, the interview answers of four respondents, of which, two are considered experts within the field of social media. The choice of suitable respondents was strategic with the goal of covering as large a portion of the social media field as possible; one social media educator that works with companies and one who assists companies with social media applications. The remaining two respondents work in marketing and communications and employ, as part of their job, social media tools such as Facebook and Twitter.

Kuna Yala ? Effekter av lokal involvering inom destinationsutvecklingen : B-uppsats

This essay has examined how the local community is involved with the tourism development on the San Blas islands and how it effects the destinations development. The method of choice has been a qualitative interview with an operator that offers trips to the destination. Also there has been made a literature study where previous research about the San Blas and the subjects of choice is being presented. During the writing process of this essay it has become obvious to us that the local community (Kuna Yala) is very much involved in everything that concerns the destination. We can thereby establish that the local community of San Blas can be placed on the top step of Arnsteins (1969) ?Ladder of Participation?.

Vad är svaret på tidningsdöden? : En kvalitativ studie om unga universitetsstudenters nyhetskonsumtion

The media industry, and especially the news, in Sweden is living in a dark world that seems to get even darker by the minute. According to Nordicom (2013) the number of readers in the ages 15-24 has dropped by 24 percentage points between 2007 and 2012. This is a big problem for the news industry, but also for democracy that require citizens that are well-read and know what is going on in society. Enda and Mitchel (2013) found that 65% of people in the USA have stopped reading a certain news source since it no longer fits their needs. Maybe with a better understanding for young adults needs this trend can change.This qualitative study was conducted using interviews with eight respondents to find out why young adults who study at a university consume news.

Metoder för trådlös gästaccess

Idag är intresset för högpresterande betong (HPB) växande runt om världen då fördelarna är många, eftersom slankare, tätare, starkare och lättare konstruktioner kan tillverkas. Detta examensarbete handlar om materialförsök och modellering för en typ av HPB som ska användas i husbyggnation. Arbetet inleddes med materialförsök i färskt tillstånd, där god gjutbarhet och konsistens eftersträvades. Utgångspunkten var från ett grundrecept med två olika ballastsorter (slaggballast med flygaska och krossballast från asfaltindustrin med silikastoft), vilka namngavs till pilotförsök 1 och pilotförsök 2. Vidare valdes pilotförsök 1 att provas i hårdnat tillstånd då det visades att det var mer ekonomiskt lönsam eftersom ballasten inte behövde siktas, lägre vct tillhandhölls och att flygaskan som användes i pilotförsök 1 är billigare än silikastoft som användes i pilotförsök 2. Resultaten efter 28 dygn för de materialförsök som utfördes i hårdnat tillstånd var:Tryckhållfasthet; 141,9 MPaDraghållfasthet; 7,0 MPaBöjdraghållfasthet; 10,0 MPaElasticitetsmodul; 46,4 GPaKrympning efter 56 dygn; 0,5 ?Samtliga försök utfördes enligt svenska standarder (SS). Dessutom vidareutvecklas och förbättrades ett redan arkitektoniskt gestaltat Attefallshus ur ett konstruktions- och hållbarhets perspektiv, där fokus låg på transport- och produktionsförutsättningar.

Känslomässiga utmaningar i socialt arbete ? vad betyder strategier och yrkeserfarenhet?

The aim of this study was to gain a greater understanding of what social workers perceive to be mentally demanding and emotionally challenging work, and which strategies they use to handle it. I chose to interview six social workers, three of them had long experience of social work, and three of them had worked for less than a year. The justification for this choice wasthat I wanted to interview people with different experience of social work over time, to be able to see possible differences in what was perceived as mentally demanding and emotionally challenging work, and how it was handled. The social workers were interviewed with a semi structured interview manual.The results showed that the organization of the social service is not fitted to the work that social workers execute. This means that what is perceived as mentally demanding and emotionally challenging work largely depends on this.

Thinking more like a client. : Designfaktorer som påverkar valet av tjänsteföretag.

Companies in the western world can no longer compete by using traditional means such as product and price since the commerce of services continually grows. To avoid similarity and increase competitive advantages modern companies have to be more specified. The competition between companies has increased and customers are harder to reach. Customers of today can afford luxury but trend indicates that originality, identity, and status are more important than factual needs. Products created and consumed at the same time within the service market are often very homogenous (similar).

Styr genus valet av Cover Story? : En fortsatt studie på projektet Cover Story, där genusaspekten kommer upp till ytan på ett intressant sätt.

Cover Story is a project, which students at Lillholms - and Ekholms School worked in during spring and fall of 2009.
