Metadonunderhållsbehandling : en gråzon för kvinnor?
The aim of this thesis has been to investigate women's experience of the Methadone maintenance treatment and what help they believe they need to be able to recover and to improve their social life and whether the medical- and social workers share the similar view.Our method of investigation has been qualitative interviews with four women in the program, two nurses and a counsellor at the methadone clinic and two social workers, who have female clients in the program.The questions at issue were:* how did the women describe their life situation during treatment, compared to the situation they had while they were addicted to narcotics,* did the women experience that the treatment they get in the methadone maintenance program is giving them a better social life situation,* did the employees at the clinic and at the social office share the similar view about the treatments as the female patients?Main problems seemed to be; meeting new non-addictive friends and finding something to do. We could se that, in different ways, they need more support. It wasn't always clear to the people who work with them whose responsibility it was, depending on workplace and/or personality..
Framtagning av automatiskt system för hantering av arbetsorder till SAAB 340
Som dom flesta underhållsbolag jobbar även TAM (Täby Air Maintenance) med arbetsordrar. Dessa för att visa vilka arbeten som skall utföras, var de skall utföras och hur de skall utföras. Uppgiften som tilldelades var att effektivisera TAM:s (Täby Air Maintenance) arbetsordersystem på flygplansmodellen SAAB 340. Deras nuvarande tillvägagångssätt är att arbetsordern först läggs in manuellt i Microsoft Excel för att sedan redigeras och anpassas för den specifika kunden. Arbetsorden delas upp i olika sektioner av flygplanet, detta görs för att underlätta teknikernas och mekanikernas arbete när de bestämmer hur arbetet skall fördelas.

Södermalmsskolan : en fallstudie om hur arbetet med en skolträdgård kan bedrivas idag
The purpose has been to, by the means of literature studies and conversation,
give landscape architects, teachers or other interested people an increased understanding
of school gardens as a phenomenon. One episode in the essay describes
school garden?s historical background and how its ideology has changed as the
society has developed. A conversation with a spokesperson for Södermalmsskolan
in Stockholm, depict how a communal public school handles the management
of a school garden today. I have also wanted to present the conditions that society
and the schools organisation has put on the management of the garden on this
particular school.
In the year of 2007 Södermalmsskolan got the opportunity to found its school
garden thanks to the environmental campaigns that were realized by the city of
Stockholm.
Förutsättningar att utforma stationsbatterier i vattenkraftverk med Li-jonteknik

Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power.The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand.
Belastningsskador vid montering : Påverkan på svensk tillverkningsindustri och hur effektivt förebyggande kan bedrivas
AbstractAccording to research made by Statistics Sweden on the members of the labor union IF Metall the number of reported musculoskeletal disorders for employees working under the collective bargaining agreement for the automotive industry has almost doubled since 2003. During 2004- 2006 and 2008 male assembly workers were the occupational group with the highest amount of reported work related disorders in Sweden. To prevent musculoskeletal disorders is according to Rose and Orrenius important both for the individual, the society and the industry by reducing economic and personal costs. The purpose of this paper is to identify and analyze how the manufacturing industry is affected by musculoskeletal disorders that occur when working with line assembly and how companies can prevent them. The report aims to provide the reader with an understanding of what musculoskeletal disorders are, to which extent they occur in assembly, how companies are directed by laws and regulations and how they affect the Swedish manufacturing industry and their employees.
Diagnos av stiktion i reglerventiler för prediktivt underhåll
This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.
DISA: en depressionsförebyggande metod för tonårsflickor : Deltagarnas perspektiv och deras sinnesstämningsförändring
Background: Mental ill-health among adolescents is one of the most increasing public health problems in Sweden. Particularly girls suffer from mental and psychosomatic symptoms. The National Board of Health and Welfare recommend the DISA method as a preventive measure. Problem: Investigations has been done of the DISA method, but further investigations needs to be done. Aim: The aim of the study was partly to investigate how participants in DISA groups in two counties understand the method and its eventual effect and partly how their mood change, to contribute with knowledge to the development of the DISA method.
Zoonotic respiratory infections and great ape conservation - an emerging challenge
The conservation of great apes faces many challenges, one of which is the threat of infectious disease outbreaks. Zoonotic transmission of respiratory diseases from humans to wild great apes has recently been confirmed. Since respiratory disease is one of the major causes of
death in both gorillas and chimpanzees, this gives reason for major concern.
Little is known about the risks of disease transmission from humans to great apes in natural environments, and there is a need for systematic risk evaluation. Researchers, conservation staff and tourists spend time in very close proximity of wild great apes, sometimes during
long time periods, which poses a potential risk of disease spillover. However, the presence of researchers and tourists has been shown to decrease the risk of poaching, making the matter increasingly complex.
Flygbesiktning av Luftledningar : Modellering av samband mellan besiktningsanmärkningar och systemtillförlitlighet
This paper thoroughly investigates needs and requirements for overhead distribution feeder inspection and develops models to investigate possible relations between short term inspections remarks and outages. The study was conducted in collaboration with Fortum Distribution AB that supplied extensive information about their overhead power feeders concerning both inspection and power outages. The investigated models where lognormal linear model, Poisson generalized linear model and negative binomial generalized linear model. All models were implemented utilizing offset terms to compensate for differences in feeder length and amount of overhead versus underground feeders. The Poisson generalized linear model was rejected at an early stage due to overdispersion and neither of the remaining models fit the data perfectly.
Analys av data från flyglaserscanning :
In forestry there are always needs of forest data to make good strategic decisions of different actions and economic winning. Usually this data gets from field-estimations made by forest workers with expensive costs and sometimes unsatisfied quality.
StoraEnso Skog is a great forest company in Sweden and they have part of the responsibility of the forest own by Bergvik Skog. Bergvik Skog is owner of 1, 9 million hectares productive forest land. Both Bergvik and StoraEnso have great interest in new inventory techniques to get the important forest data.
The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna.
Att hjälpa andra trots risk : motivationen i det internationella biståndsarbetet
The purpose of this study is to examine what motivates people to help others at risk to themselves. The focus is on international aid workers, which in their work put themselves in situations of risk. Earlier research shows that international aid work involves risks such as infectious diseases, violence, death threats, assaults, constant insecurity and risk to be traumatized etc. There is not much research done on what motivates to help others in spite of risks, hence we find this an interesting area. We have interviewed six respondents about the content and character of their motivation and factors that are important for the maintenance and development of this motivation.
Implementering av underhållssystem vid en tillverkande industri.
Företaget som studien utförts på upplever ett problem vid hanteringen av underhållsarbete i fabriken. Processerna för felrapportering och beställning av reservdelar är tidskrävande och involverar arbete från flera olika parter. Merparten av allt underhållsarbete som utförs är av oplanerat slag och ett fungerande uppföljningsarbete för att komma till rätta med de pro-duktionsstörningar som äger rum i processen saknas.Syftet med examensarbetet har varit att skapa underlag för att förbättra företagets effektivitet genom att optimera underhållsarbetet med hjälp av förslag till ett underhållssystem och olika tillvägagångssätt för att effektivisera underhållsarbetet.Under arbetets gång har en underhållsloggbok utformats i Excel. Loggboken används till att logga alla underhållsarbeten som inträffar i produktionen. Dessa arbeten ligger till grund för merparten av de beräkningar som utförts under projektet.Beräkningarna syftade till att kartlägga var i processen flest fel inträffar och av vilken karaktär dessa fel är.
Teststrategier och användning av testautomation : En studie utförd på företaget Extenda AB
In today?s IT world where software is constructed in a rapid pace, testing has become a crucial area to master when testing has to be done at a greater speed. To still be able to handle the demands of high quality software, companies have to spend more resources on testing and introduce test automation. By automating test cases the testers can gain time which they can spend on doing more complex testing and thereby increase the quality of the software.In this thesis we have helped Extenda AB, who delivers systems to retail companies, to introduce test automation in one of their customer specific projects. This has been done using their own in-house ?capture/replay? tool ECP (Extenda Cashier Player).We have also derived a process that explains how Extenda can introduce test automation on other customer projects.
