The purose of the study is to increase knowledge regarding systematic enviromentarl work in an organization that works with road services. Work on the road is done in a hazardous environment with constant danger regarding the life of the individual. The site of the work varies in accordance with where the needs ae . This requires skilled workers capable of working independently and that they are experienced din doing their own risk assessments in accordance with the individual believes that the situation calls for work to be performed safely. The study was conducted with a qualitative research approach in which four employees of different positions, knowledge, experience and vision to work in a hazardous environment were interviewed. The focus rests on the organization, management, and individual aspirations for a safe and secure working environment. The study adds weight to the relationship between the purchaser of the work and the organization as a prime contractor due to the compexity of the organization.

ABSTRACTBackgroundWhen faced with an unexpected cardiac arrest the ambulance nurse is in responsible for taking advanced actions to create a clear airway. Two accepted methods for this is endotracheal intubation and application of laryngeal mask.AimThe purpose of this study was to examine the use of endotracheal intubation compared to application of the laryngeal mask in unexpected cardiac arrest.MethodLiterature study with quantitative approach. A systematic search of 21 articles comparing the laryngeal mask with the endotracheal intubation has been made using Pub-Med and CINAHL. A quality review according to Forsberg and Wengström has been made.ResultsLaryngeal mask had a higher rate of successful applications compared with endotracheal intubation. Time for applying the laryngeal mask was shorter in seven out of ten of the studied articles.

Edsbyverken Office Furniture has over the past 100 years been producing delicate carpentry products, chairs and skiis, but more recently the focus has shifted to furniture for the modern office environment. With a wide selection of products and its characteristic neutral design, Edsbyverken has an extensive group of clients both in Sweden and internationally. The aim of my C level thesis project was to examine the materials Edsbyverken is currently using in order to develop new designs or product functions. Simultanesously, I also wanted to verify whether the method I developed for this project - to initially undertake a comprehensive study of the chosen materials and thereafter specialise on a certain product and target audience ? was effective and successful.

Syftet för denna studie var att studera förekomsten av postoperativa sårinfektioner hos patienter som genomgått kärloperation med inguinal incision under åren 2008 till och med mars månad 2013. Undersöka skillnader gällande riskfaktorer inom studerad patientgrupp för förekomst av postoperativ sårinfektion samt studera om patienter som utfört endovaskulär metod under samma vårdtillfälle oftare drabbades av postoperativ sårinfektion än de patienter som inte genomgått endovaskulär metod under samma vårdtillfälle. Metoden som användes var granskning av patientjournaler efter utifrån studien utvalda specifika operationskoder. Granskningen av de 54 patientjournalerna skedde med hjälp av egenmodifierad tidigare använd granskningsmall. Studieresultatet visar att förekomsten av postoperativa sårinfektioner hos den studerade patientgruppen uppgår till 22,2 %.

The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below. Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment. Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.

Det elnät som vi nyttjar idag är uppbyggt sedan 1900-talets början och är byggt för att hantera den 50 Hz som används vid kraftöverföring. På senare tid har vårt elnät börjat nyttjas för annat än bara kraftöverföring. Det kan handla om kommunikation mellan apparater eller kommunikation till elbolagen för fjärravläsning av elmätare. Denna kommunikation sker på högre frekvenser än 50 Hz och sträcker sig vanligtvis från 9 kHz – 95kHz beroende på vilket system man använder. Det faktum att våra apparater har utvecklats i ett högt tempo har även det lett till att dessa använder en modernare teknik som alstrar högfrekventa signaler på vårt elnät. När nu vårt elnät, som är byggt för att hantera 50 Hz, utsätts för alltmer högfrekventa signaler så uppstår nya problem i vårt elnät och det jordsystem vi har idag är inte tillräcklig för att hantera de högre frekvenserna. Skyddsjorden som finns i våra hem finns för att förhindra att människor och djur skall komma att skadas av elektriska strömmar.

Benthic invertebrates play important roles as feeding resources for many organisms in different food webs. Shifts in predation of these organisms can generate cascading effects and potentially lead to the disappearance of one or more species from a site. Cascading effects can bring impacts to organisms who aren?t even directly involved, why studies in this field are important for understanding sudden changes in ecosystems. I examined the predation from fish and waterfowl on benthic invertebrates in the shallow and eutrophic Lake Tåkern in the plains of Östergötland County, southern Sweden.

The purpose of this study is to understand encounter by individual depictions of meetingsperceived by social workers and clients in social services. Thus, we want to understand moreabout how clients and social workers as actors encounter each other in meetings in the socialservices. The study also aims to understand how the two actors affect each other in this typeof interaction and whether there are other influencing factors. We conducted a qualitativestudy by interviewing informants with semi-structured interview questions. The informantswere comprised of three social workers and eight clients.

The objective of this study is to examine the sustainability of recovering industrial wasteheat from several heat sources in a foundry constructed in a plant belonging to ITT Waterand Wastewater in Emmaboda, Sweden. A triple bottom line perspective will be appliedto achieve this objective. The triple bottom line approach takes into account ecologicaland social performance in addition to financial performance. The technology forrecovering the waste heat is a Borehole Thermal Energy Storage (BTES) which is aconstruction consisting of 140 vertical boreholes, 150 meters deep with an internal spaceof four meters.The calculated amount of energy for storage is approximately 3800 MWh annually. Ofthis amount 2500 MWh are expected to be utilized, while storage losses accounts for theremaining part.

This is a study, the purpose of which is to investigate how the construction company Sefab Bygg AB is able to increase its profitability and render a more efficient production process through logistic solutions. The study is made during one of Sefab´s present projects. The project includes sanitary renovation of 650 apartments in the co-operative Opalen in Norrköping.To find out whether changes of logistic routines are profitable or not, it?s necessary to evaluate the total cost of the changes. A total cost analysis is a mapping of all the costs for a particular material, on one hand for the present situation and on the other after the change.

In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. The purpose of this study was to compare swimming behaviour in the river before spawning, the choice of spawning areas and body size between wild and hatchery-reared salmon in the river Klarälven. Salmon behaviour in the river before spawning was analyzed using radio telemetry. The salmon were caught at Forshaga power plant, radio-tagged and returned to Klarälven at Ekshärad, 107 km from the river?s mouth.

The productiontime in the construction industry contains of many different participants which will take part in different events. When there is so many people working with the same project it is easy tosee one self just as a part of the game. The consequence of this is that they don?t see themselves as important participants whos knowledge, opinions and experience can be useful in the whole production process. This might lead to that they feel neglected and the consequence of that will be lackof motivation.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Abstract Essay in political science, C-level, by Patrik Larsson, autumn semester 2007.Tutor: Susan Marton The battle over the agenda-Can media be regarded as an individual political actor? The purpose of this essay is to study to what extent media can be regarded to function as an individual political actor. In other words, do the media have more power over the political agenda than the politicians and do the media influence how the politicians make their decisions. This research is a case study and to be able to complete the intention of this study I have used Maxwell McCombs and Donald Shaws theory, the agenda-setting theory. From this theory I have used four aspects to analyse my material which has consisted of editorials from a Swedish newspaper, interpellations and debates that belong to the interpellations. The aspect I have worked with are, how the problem is defined, who is responsible for the problem, what values and which solutions are expressed.  I have used a qualitative text analysis as my methodological approach which means that the results of my study are my interpretation of the material. My conclusions are that the media in this case shouldn?t be regarded as an individual political actor because there is no tendency that shows that the media has influenced the government in their decisions concerning the real-estate tax.

Studies in the recent years have showed that the preschool playground is important for both the physical and emotional development of children. The Botkyrka local government has decided to improve their preschool playgrounds in order to take advantage of these studies. The administration of childcare and education in Botkyrka is arranging a network between the different preschools where they work together to improve their outdoor environments. The network is arranging workshops and seminars where people from the different preschools can come and gain inspiration for improvements of their own preschools. The administration of properties has created a document where they describe the changes that are supposed to be made to the different outdoor environments. Through the administration of properties and the person who is responsible for the outdoor environments I was introduced to their work with the preschool playgrounds.
