This thesis aims at determining the heat losses in a property vent stack and its roof valve. Upon request of a company, the vent stack is analysed for possible heat recovering solutions to be implemented, while relining of the drain system is executed and with a suitable payback time for the economic investments. The heat loss calculations are based on data for properties that are located in the Stockholm region, but also easy to change depending on the situation. The calculations are done on pipes made out of cast iron, which still is the most common type of drain pipe in Sweden, and these are the pipes that relining is usually made on. The calculations that needed to take several variables into account have been done in MatlabR2014a and the thermos dynamical properties that were used in those calculations have been extracted from EES.Three different types of heat losses in the vent stack have been taken into consideration in this thesis.

This thesis applies to a novel steam expander, one part of a steam engine system, a wobble plateengine. The piston in the expander moves axially with the outgoing rotating shaft and is locatedon a plate, why the engine type is called axial engine. When steam is applied to the plungers theplate wobbles creating a rotation on the shaft going thru the wobble plate. The steam expander issupposed to be used in exhaust gas recovery (bottoming cycle) applications and small scaleenergy production. The commissioner is Ranotor Utveckling AB.

Different Perspectives is a study of detainees' and guards' experiences of the remand prison. The result of the study shows that the remand prison brings forth the individuals anxiety, stress and fear. The individual detained in remand prison have a great need for contact with their families, but also with the guards. In the remand prison there is always a great level of control and always some kind of power practised. It is the guards who have the power and the competences to make the individuals detained in remand prison follow the rules and do what they have been told.

 Syfte: Den bakomliggande tanken med vår uppsats är att belysa tjänstekvalitet från ett kund- och medarbetarperspektiv. Vi ville dels undersöka medarbetarnas uppfattning om det egna företagets tjänstekvalitet och dels kundernas uppfattning av och förväntningar på företagets tjänstekvalitet. En annan aspekt som undersöks är hur kundrelationens längd påverkar den kundupplevda tjänstekvaliteten.Metod: Både sekundär- och primärdata har använts i uppsatsen. Vi har genomfört en litteraturstudie för att söka kunskap inom området tjänster och tjänstekvalitet. Därefter genomförde vi en förstudie i form av interjuver med befintliga kunder till företaget och slutligen gjorde vi en kvantitativ undersökning.

Erfarenheter av detta gav inspiration till denna studie. Hur upplever människor att vara del av en organisation? Syftet med studien var att sammanställa beskrivningar av upplevelser från beprövade sätt att organisera omvårdnadsarbetet inom sjuksköterskans område.

Syfte och frågeställningarStudien avser att undersöka hur idrottsföreningar upplever LOK-stödet. Följande frågeställningar har valts för att uppfylla syftet:? Hur fördelas det statliga LOK-stödet i föreningarna?? Hur anser föreningarna att arbetet med aktivitetskort fungerar?? Vad betyder LOK-stödet för föreningarna?? Anser föreningarna att LOK-stödet är ett rättvist system för att fördela pengar till ungdomsidrotten?? Finns det någon skillnad mellan stora föreningar (>500 medlemmar) och små föreningar (<50 medlemmar)?MetodStudiens mätinstrument utgjordes av enkäter och omfattar 2000 slumpvis utvalda svenska idrottsföreningar som uppbådar statligt LOK-stöd. Urvalet utgjordes av föreningar som ingår i RF:s organisation. Ur RF:s medlemsregister valdes sedan var tionde förening ut, oavsett verksamhet, storlek och regional tillhörighet.Studien är ett samarbete mellan IH och RF där RF angav vad de ville ha undersökt.

In Sweden the work of reducing acidification and its prime cause; emission and deposition of sulphur dioxide, has been going on for decades. Despite of all the work that has been done the positive progress in the acidified areas is slow. This is partly due to a long recovery time for the acidified areas but also because the reductions of emission and deposition of sulphur dioxide have not been large enough. Emissions of sulphur dioxide from land based source in Sweden are estimated to 34 000 tons in the year of 2010. During the same year, approximately 182 000 tons of sulphur dioxide will be deposited over the Swedish territory.

In early January 2010 the authors participated in a meeting with the chief engineer for a company in which a central part is manufacturing of printed circuit boards (PCB). At this meeting it emerged that the machinery and production methods have changed substantially since the early 1990's. The spreadsheet for preliminary production time calculations by the company is today based on conditions from almost 20 years ago. The company has over the years been trying to adjust the spreadsheet template. The result of these adjustments has filled it with historical residue, something which makes the template difficult and time consuming when the primary user tries to handle it.The purpose of this study was to help the company increase its accuracy in the representation of the production times for the different PCB-based products by developing a new costing model based on an already existing but inadequate spreadsheet template. The company also expressed the wish that the new costing model would be less time consuming to work with.The methods used to achieve the goal are interviewing, participatory observations and meetings with relevant persons. The data obtained were analyzed using the theory on PCB production and visualization of data.

We got in contact with Marco AB, who we?ve had contact with before concerning earlier projects, to find out if they were interested in arranging a larger project for our last class (Examensarbete 15hp). They were very positive to this proposition, and soon they offered us a project regarding reconstruction of their current mechanical device that absorbs all the force from the lift itself when it is at a predefined level (sv. sjunkspärr). The current solution does fulfill the requirements that are given, however it is not a solution that gives a high level of satisfactory.

Laminitis has crippled horses through times and many cures have been used to treat it. Since the mechanism of the disease is yet not fully understood, treatments are only ways to alleviate the pain and at best, slow down the pathological process enough to make time for improvement. This paper is a retrospective study of 71 horses treated by a protocol at Hästsjukhuset Strömsholm. The protocol implies three visits at zero, five and fifteen weeks. At each the horse is evaluated and treated by a veterinarian.

Ett företag med ett flertal leverantörer måste på sikt välja ut vilka leverantörer man önskar arbeta aktivt/passivt med. För att kunna göra detta krävs att man tar fram konkurrenskraftiga leverantörsstrategier som bygger på välgenomtänkta beslut. Dessa beslut måste ta hänsyn till inköpets totala risk för leverantör och komponent. Den totala risken är oftast väldigt specifik för varje företag och bygger på ett flertal olika parametrar. Författarna ger i denna uppsats förslag på tre parametrar som kan hjälpa företag att ta fram effektiva leverantörsstrategier.

Cryptosporidium parvum is a protozoan parasite causing diarrhoea in many different animal species including cattle and man. It is an important enteric pathogen in neonatal calves and it is the second most common pathogen found in diarrhoeic calves in Sweden. Subclinically infected adult cattle have, in international studies, been shown to shed a low number of oocysts in faeces and this has been recognised as a potential source of infection for new-born calves. The detection methods used for diagnostic purposes are based on microscopic investigation of faecal smears. These methods have a fairly low sensitivity and samples from subclinically infected cattle have to be concentrated before analysis.

The aim of this study is to understand the collaboration at a child investigation and the actions that may be encountered as a result of the investigation, based on the Social Secretaries experiences of collaboration with other agencies such as schools, police, health visitor and child psychiatry. In the study, eight social workers from different municipalities was interviewed at a total of six occasions. One of the occasions was a group interview with three social workers at the same time. Through the interviews, it appears that the collaboration has an important role in social work and the necessity is something that manifests itself in the social secretaries stories but also in the earlier research done in this area. The results show that social workers extensively want to interact but that the purpose of interaction varies depending on the nature of the matter.

The purpose of this work is to find out what female students think about Skogsmästarprogrammet (Forest Management ? Bachelor?s Programme) at the Swedish University of Agriculture. The programme has existed since 1945 and in total over the years 1974 - 2007 about 10 % females have been studying at the programme. Today 15 % of the students are women, and the goal is to reach at least 30 %. The central question in the present work is to investigate how it is possible to increase the proportion of women.
