Fuel pellets are a refined bio fuel mostly consisting of residues from sawmills and wood industry. At Rindi Västerdala AB's combined bio energy plant in Vansbro fuel pellets are produced, while the waste heat from the process is used for district heating. The pellets are produced from sawdust, wood shavings and dry wood chips that is dried, milled and pressed into small cylindrical rods. The advantage of refining the wood material in this manner is that the energy value is greater per unit volume and unit weight, thereby the cost of transportation per energy unit is reduced. Also, less storage space is needed.Pellet manufacturing is a complex process since many parameters affects the final results.

The purpose of this thesis is to investigate and clarify the facts surrounding one of Vattenfall's district heating plants; The "solar field" and associated rock cavern in Lyckebo, Storvreta. The plant was built in the '80s by the formerly municipal utility,Uppsalakraftvärme AB, as an experimental building. A ground water filled cavern would serve as seasonal storage of solar heat from an adjacent solar field. Since both the energy company and the facility itself has undergone major changes over the past 30 years, there was a great need to gather facts in order to provide a picture of its current condition and potential for continued use. The thesis investigates the plant's history and problems with the rock cavern losses, and how the operation developed. It also presents the calculations regarding the possibilities of again supplementing the facility with solar energy - which is not the case today - as well as the economic conditions for it. Regarding a re-launch of solar energy, primarily a concentrating solar collector has been studied, as it has the advantages of an integrated control system.

Enligt senast sammanställd statistik avled 91820 människor i Sverige år 2007. Vem som bör lämna ett dödsbud bestäms i enskilda fall med utgångspunkt i att de anhöriga bör visas hänsyn och omtanke. En sjuksköterska är oftast den person som möter de anhöriga då de får ett dödsbud. Syftet med denna studie var att undersöka hur sjuksköterskan bör hantera ett dödsbud till anhöriga. Studien har genomförts som en litteraturstudie.

The aim of the study was to examine how child investigators in the police force interpret and apply the notification of preliminary investigation (FuK) and the po-lice act in their child investigative interviews with alleged victims of sexual abuse. Questions at issue were how child investigators relate to FuK 17-19 §§, re-garding child investigative interviews and to FuK 16 § and the police act 3 §, re-garding their co-operation with social services. The theory and method used in this study was Sociology of Law. Qualitative interviews were conducted with eight child investigators, one from each police district in Stockholm. The results of the study conclude that despite special qualifications, child investigators may find themselves in difficulty in receiving or interpreting information from chil-dren, therefore they may need to consult a person with expert knowledge.

The purpose of this thesis is to shed light on the various factors that influence the balancebetween the working lives and family lives of social workers. The research questions posedwere: Do social workers consider there is a conflict between their working lives and familylives? Which factors make maintaining a balance between working life and family life moredifficult and which make it easier to do so? How do social workers describe equality betweenthe sexes in their own family? Regarding methodology, the selection method is strategic andcombines data sources with quantitative and qualitative methodologies. The material collectedand via online survey, targeted to 120 municipal employees social workers in a district councilin a big city, and through interviews with four social workers in a rural community. The studywas performed using gender theory and the demand-support-control model.

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.

Syftet med denna studie är att göra en metaanalys kring användningen av utvärderingen Aktiveringspolitikens Janusansikte. Utvärderingen har genomförts i fyra stadsdelar i Malmö inom ramen för storstadssatsningen.Fokus har legat på att undersöka om resultatet av utvärderingen Aktiveringspolitikens Janusansikte har använts i de utvärderade verksamheterna, samt vilka faktorer som påverkar användande eller icke-användande av utvärderingar.För att analysera vilken typ av användning som har förekommit har Carol H Weiss modell för användning av utvärderingsresultat används. Denna har kombinerats tre förklaringsfaktorer för att försöka förstå varför det sker eller varför det inte sker någon användning av utvärderingsresultat. Dessa faktorer är den personliga faktorn, den kontextuella faktorn och utvärderingsfaktorn.Undersökningen visar att användningen av Aktiveringspolitikens Janusansikte inte varit så utbredd i de undersökta stadsdelarna. Däremot framkommer det en generellt positiv inställning till utvärderingar.

With increased deployment ofintermittent renewable energy, such aswind and solar power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would bepossible to integrate into existingpower generation such as a combined heatand power plant, and how the technologypotentially could function in theelectricity market. ThermoelectricEnergy Storage consists of a chargingprocess and a discharging process, bothoperating by the working fluid CO2. Toincrease the efficiency of theThermoelectric Energy Storage, wasteheat from the district heating networkis integrated.A model of the Thermoelectric EnergyStorage has been developed and it wascalculated by thermodynamic propertiesof the working fluid, CO2, in thevarious process steps.

The purpose of this report is to find out what different preferences forest owners have in the region where Norrskog have their operation area, what they prefer and think about Norrskog. The purpose is also to compare some of the questions to a similar study that was made in 2008. The study is made in cooperation with Norrskog which is a forest owner cooperative. Norrskog has about 13 000 members which is about half of all forest owners in the region. To get the answers from the forest owners, questionnaires were sent out by mail. 371 were sent out and 102 came back. There were more members of Norrskog that responded than it was nonmembers. The results indicate that the forest owners have long term perspectives, their priorities are to nurse the forest so they can get the profit later on.

AbstractThe purpose with this essay is to get knowledge about the consequences that speech-defects bring for children in pre-school ages. I got interested in this matter when I, during my teaching practice, got in touch with children carrying this specific disorder. I chose to apply qualitative interview as a method to investigate this and as a starting-point I used these aspects: How does speech-defects affect learning, understanding, friendship relations, and development in general?I interviewed three pre-school teachers in two different schools. One school in a smaller district and the other one in a middle-sized town, in the middle of Sweden.

Syftet med denna systematiska litteraturstudie var att i vetenskaplig litteratur utifrån sjuksköterskornas perspektiv undersöka vilken inställning sjuksköterskor har till opioidbehandling i palliativ vård. Metoden baserades på systematisk granskning och analys av åtta vetenskapliga artiklar.Resultatet av denna litteraturstudie visar att kunskap och erfarenhet har en positiv påverkan på sjuksköterskornas inställning till opioidbehandling i palliativ vård. Resultatet visade också att sjuksköterskor med kort arbetslivserfarenhet, sjuksköterskors ovana i omvårdnaden av svårt sjuka och döende patienter samt de sjuksköterskor som inte visar förtroende för opioider som behandingsform är motvilliga till opioidadministration..

Med ett energikombinat vid Lillesjöverket vill Uddevalla Energi energieffektivisera samt sänka temperatur på återkommande fjärrvärmevatten, för att kunna utnyttja rökgaskondensorn effektivare. Uppdraget var att utreda mängden tillgänglig energi under sommarhalvåret och utföra en matematisk kalkyl som ska ligga till grund för val av tork. Valet stod mellan två alternativ av tork där storlek på värmeväxlararea och investeringskostnad skilde dem åt. Sedan följde dimensionering av fjärrvärmeledning samt cirkulationspump från fjärrvärmenätet till tork. Syftet var att ge Uddevalla Energi ett tekniskt beslutsunderlag för val av storlek på tork samt dimensionering av energiöverföring till densamma.

Studiens bakgrund beskriver att kommunikation är sjuksköterskans viktigaste redskap. Andra faktorer som har betydelse för det korta mötet är tid, miljö, makt, bekräftelse och närvaro. Travelbee menar att för att förstå vad omvårdnad är och bör vara, måste man förstå vad som sker mellan patient och sjuksköterska, hur denna interaktion kan upplevas och vilka konsekvenser detta kan få för patienten och hans tillstånd. Syftet med studien var att identifiera faktorer som påverkade patientens upplevelse i det korta mötet med sjuksköterskan. Litteraturstudien baserades på 14 vetenskapliga artiklar vilka belyste patientens perspektiv.

AbstractThere is a general perception that women are victims and men are the perpetrators of sexual offense. Female perpetrators of sexual crimes have been neglected in the research literature, because female sex offenders do not live up to preconceptions of female as motherly and caring. Females tend to be responsible for a very small portion of all crimes and are estimated to account for 1-2% of all sexual offenses. Theories use to discuss female sex offending include neutralization of behavior, mental health and feminist theory. The aim of the present study was to describe female sex offenders and examine the relationship between the perpetrator and the victim by analyzing court judgments.
