Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged. The milling process creates a wide range of particle sizes.

The overarching purpose of the study was to examine the effects of infant massage and to put these effects incontext with mother ? child attachment. The intention was also to study whether these effects have any relevancefor social work. This was accomplished by studying earlier research, theory and laws but also through interviewswith mothers who have followed through a course in infant massage. The main questions of the study was: Afterthe completion of the course and after using the massage technique at home, does the mother experience that thebond with their child is influenced by the technique and are the mothers more apprehensive of their child?ssignals? Has the mothers observed any signals from their infants during the massage and if so what has beentheir reaction? Does the mothers experience that the massage has provided any physiological effects? Has thecompletion of the course provided the mothers with knowledge that?s had an effect in their ways of parenting? Inwhat way does the earlier research, reports and laws deal with the benefits and risks of a secure or insecureattachment, and can the quality of the attachment have any meaning in the social work? A qualitative approachwas chosen with respondent-interviews.

Most of today?s concrete structures that are built on site are mainly constructed in a traditional fashion with a lot of artisanal operations. One step towards industrializing the in-situ construction of concrete is to use prefabricated reinforcement. Through this method there can be a lot of savings when each bar doesn?t have to be placed and fixed separately on site.

Behavioral problems are one of the leading reasons for re-homing and euthanasia in dogs. It is estimated that between 40 ? 87 % of dogs suffer from some sort of behavioural problem, making it an important animal welfare issue. Separation anxiety is one of the most common behavior problems encountered in dogs after problems related to aggression. This thesis is aimed at examining the etiology behind separation anxiety related behavior in dogs based on existing literature as well as comparing and evaluating the efficiency on suggested treatment protocols.

The purpose of my study was to visualize how teachers works with multilingual children in pre-school, the methods used to stimulate and develop primary and secondary language and how teachers does see second languages development with the help of the primary language. The study consists of qualitative methods in form of interviews which are made with four teachers who work within the pre-school. The findings during the collection of data (interviews) are going to be connected to the relevant literature on the subject I have chosen.The result showed that the concrete materials are used to stimulate and develop primary- as the secondary language and that the teachers have different opinions on secondary languages development with the help of primary language even if the primary language seems to be an important asset of all teachers that I interviewed..

Detta examensarbete har genomförts på uppdrag av CBI Betonginstitutet. Handledare till examensarbetet har varit professor Johan Silfwerbrand från CBI och examinator Per Roald från Kungliga Tekniska Högskolan i Haninge.  Idag är betong ett byggmaterial som används i stor omfattning tack vare sin beständighet, miljövänlighet och lönsamhet. Betong hittar man i både gamla och nyproducerade konstruktioner. Även med bra egenskaper kan betong vara ofullkomlig när den prepareras på fel sätt.  För att underlätta gjutning och arbetbarhet av betong användes förut i många fall mycket vatten och detta resulterade i att beständigheten på betong försämrades. De flesta gamla betongkonstruktionerna är nu i stort behov av renovering.

In this essay, Risk and crisis management Conservation policy and normalization production, I discuss how societies, communities and individuals are responsible for the handling of catastrophes and crises. Risk and vulnerability analyzes are parts of modern risk and crisis management. The purpose of these analyzes is to prepare people and organizations for any crises. For managing this it is necessary to comprehend, be able to change mindset in creating concrete tasks and inform others.The purpose of this essay is to analyze modern risk and crisis management by studying empirical material, such as interviews, observations and literature. My aim is to combine these materials and study how they cooperate.One of the findings in this essay is that risk and vulnerability analyzes are of great complexity. These analyzes require a discussion in order to identify the development of the society's crisis management system, as well as the continued support of the individuals that have a responsibility for preventing and preparing their organizations..

Intranets can streamline workflow processes, improve communication and add value to the employees of an organization. Companies that don?t take advantage of the potential in their intranet is a common phenomenon. In connection with a migration project dealing with a switch of content management system it turned out that SAS Technical Services lacked clear objectives and strategies for the use of their intranet. Thereby they didn?t make the most of the possibilities an intranet brings.The work with this thesis began with collecting the experiences the company could take with them from the migration project.

En stor del av Trafikverkets budget går till att reparera och underhålla våra broar. Underhållsåtgärder orsakar också trafikproblem med stora miljöutsläpp och samhällskonsekvenser som följd. Eftersom broar vanligtvis dimensioneras för en lång livslängd på 120 år är det viktigt att planera för långsiktiga lösningar och förutse konsekvenserna av kommande underhållsåtgärder. Genom att använda mer underhållsfria material finns möjligheten att minska kostnaderna och koldioxidsläppen.Målet med examensarbetet är att ta reda på hur stora besparingarna är genom att svara på frågan: ?Vilka fördelar erhålls av att använda mer underhållsfria material i broöverbyggnader ur kostnads- och miljösynpunkt??.

Lining techniques such as nap bonding and mist lining were developed in the late 20th century and have gained popularity alongside with the increased use of acrylic emulsions as adhesives. The ability of the adhesive to create a nap bond to the canvases without penetrating the fibers has shown advantages regarding reversibility. In addition, the use of moisture, heat and pressure is reduced, which can be advantageous for more sensitive paintings. These lining techniques have been included in several studies where reversibility, minimal intervention and respect for the individual requirements and problems of each object have been the focus. The adaptability of the methods has been confirmed and to further explore the adaptability, this study consists of three simpler application techniques with the adhesive Lascaux 303 HV on mockups.

Denna uppsats är en socialpsykologisk och kvalitativ undersökning som syftar till att förstå hur man kan, utifrån ett socialpsykologiskt perspektiv förstå varför vissa individer ansluter sig till en huliganfirma och varför de stannar kvar. Fotbollshuliganism blev som störst i Sverige på 1990-talet och det pågår ett arbete i samhället för att försöka minska detta samhällsproblem då huliganismen innebär våld och vandalisering. Uppsatsen grundar sig på tio intervjuer med personer som har varit eller är aktiva i olika huliganfirmor i Sverige. Den vetenskapsteoretiska ansats som använts är hermeneutiken. Det insamlade empiriska materialet är analyserat med hjälp av följande socialpsykologiska teorier och begrepp: sociala band, skam och stolthet (Scheff 1994), interaktionsritualer och emotionell energi (Collins 2004), avvikande beteende (Becker 2005), maskulinitetsteori (Connell 2008), beroende och kickar (Giddens 1992), ungdomsfaser (Erikson 1988).

Sewer trenches usually contain material with a higher hydraulic conductivity then the adjacent soil. Thus they can serve as paths of preferential flow in a polluted area. Wastewater from factories can also leak from wastewater pipes and pollute the soil in the sewer trenches.The purpose of this project was to investigate pollutions in sewer trenches and in sewer pipes in the industrial area of Köpmanholmen, 20 km south of Örnsköldsvik in the north of Sweden. To make an estimation concerning the potential of transport of pollutions in sewer trenches, hydrological calculations were performed.Leakage to any greater extent did not seem to be a problem in the area. This is the case both for the concrete and the wooden pipes that have served as factory wastewater pipes.
