This thesis is about new technology in academic libraries in the form of Patron Driven Acquisition. As libraries take part in the digital era, a new model of patron driven acquisition has emerged. This model gives users more influence over the libraries electronic book collection. The collection development model changes libraries traditional role in the collection development process, from collecting for the future to the present.The purpose of this thesis is to gain knowledge of what acquisition librarians think about the effects of PDA on the collection, the acquisitions role and the cost structure. The theoretical framework relies on Christensen?s theory about disruptive technology and was used to interpret outcomes of new technology in libraries and its staff.Five librarians from four different Swedish university libraries were interviewed using a qualitative semi-structured method to carry out the investigative part of this thesis.

The aim and research questions of this study are concerned about how, and what kind of, problems and subjects that citizens raise during verbal interaction with politicians and officials in the field of participatory democracy. The theoretical framework of the study dominates by theories with a positive approach towards participatory democracy, but there is also a broader discussion on the phenomenon?s strengths and weaknesses.The case in focus of the study is a specific phenomenon of participatory democracy created by the municipality of Växjö. The empirical material that is analysed is consisted of written text based on the verbal interaction from these meetings between citizens and politicians/officials.The outcome of the study shows that most of the verbal interaction was held between citizens and politicians/officials in a vertical direction and that a major part of the responsibility concerning the raised subjects is estimated to be in the hands of the latter part. In the light of under what circumstances the meetings are practised, the democratic and collective minded performance of the citizens is argued to be in good condition, despite the dominating vertical interaction and estimation of trust..

This thesis investigates the socio- and environmental economic effects of a deep repository for spent nuclear fuel in Forsmark in the municipality of Östhammar. I seek to show the general picture but focus on the effects on employment, environment and income. Cost-benefit analysis is used to investigate the differences in utility between a scenario with and a scenario without a deep repository in Forsmark. Most of the possible effects can not be valued and many can not even be quantified with the data available today. Therefore this thesis has a bit of a ?preliminary study character? and seeks to show what we know today and what needs to be further investigated when available data allow it. The costs that could be valued are noise from the traffic during the period of building and emissions of carbon dioxide and nitrogen oxides from the transportation of rock masses during the building period.

Uppsatsen utreder ifall det finns en möjlighet till kostnadsbesparingar genom att erbjuda en stor andel av den äldre befolkningen hjälpmedel. Dessa hjälpmedel är tänkta att ha i förebyggande syfte för att minska antalet höftfrakturer. Perspektivet för analysen är samhällsekonomiskt, det vill säga alla möjligheter till kostnadsbesparingar antas tillkomma samma aktör. En uppdelning mellan landsting och kommun görs med andra ord inte. I en cost-benefit kalkyl görs en uträkning på vilken nettoeffekt som uppnås på den samhälleliga välfärden genom att antalet höftfrakturer minskar.En makroundersökning ligger till grund för de hjälpmedel som studeras.

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

Syftet med studien var att undersöka hur hög precision äldre personer har när de ålderskattar maskerade och omaskerade ansikten. 21 kvinnor och 19 män, totalt 40 deltagare med genomsnittlig ålder på 57,7 år fick skatta åldern på 30 maskerade och 30 omaskerade ansiktsbilder. Samma stimuluspersoner användes med och utan mask. Stimulusbilderna delades upp i grupperna yngre (18-32 år) samt äldre (39-72 år). Resultatet visar att omaskerade ansikten skattas med högre precision än maskerade ansikten och att kvinnor hade en högre precision än män.

This investigation?s task was to map manufacturing of special qualities at Stora Enso Packaging under a certain period, analyze if rules concerning special qualities is followed, which consequences this results in concerning use of paper, waste and costs and to give suggestions on alternative solutions. The goal was to give sugges-tions that help the company to reach its business ratio that the production de-partment uses within use of paper and productivity in the corrugated cardboard machine.Stora Enso Packaging is a part of the forest group Stora Enso and is one of Swe-den?s leading producers of corrugated cardboard. Stora Enso Packaging acts pri-mary on the Swedish market, where they have a market share of 25 %.To be able to analyze orders with special qualities we did a data collection during two months, where we mapped incoming orders.

In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.

Syftet med detta arbete är att studera de samhällsekonomiska konsekvenser som en uppstart av persontåg på TGOJ-banan, mellan Oxelösund och Eskilstuna, skulle innebära. På vägen fram för att uppfylla syftet med uppsatsen har ett antal frågeställningar pekat ut vägen och hjälpt till att föra in arbetet mot specifika problemområden. - Vilka kostnader är förenade med tågtrafiken jämfört med busstrafiken? - Vilken nytta uppkommer vid tågtrafik jämfört med busstrafik? - Hur stora är kostnaderna för järnvägen i förhållande till de uppkomna nyttorna? Ett väsentligt led i studien har varit att studera dagens resande för att kunna dra slutsatser om det framtida resande vid en uppstart av tågtrafik på sträckningen. Dagens kollektivtrafik resande, dagens resande på vägar i korridoren och resvaneundersökningar har varit faktorer som vägts in för att få fram det estimerade resandet.

This report aims to study the condominium prices in central Stockholm and the factors thataffect these prices. A linear regression model was set up and data about relevant covariatessuch as floor area, mortgage rates and where the condominium is situated were gathered toassess if and how they influence the price. The raw data was processed and enhanced to gain asmuch relevant information as possible to the model. To determine the covariates? influence onthe final price, regressions were ran and various tests were performed on the output data.

This master thesis is a study on how a rategyro triad, an accelerometer triad, and a magnetometer triad can be integrated into a navigation system, estimating a vehicle?s attitude, i.e. its roll, tipp, and heading angles. When only a rategyro triad is used to estimate a vehicle?s attitude, a drift in the attitude occurs due to sensor errors.

This report describes the tactics used by the Swedish Air Force rescue services against crashed military aeroplanes and helicopters. The aim of the report is to study and analyze the tactics used by the different Air Force bases, standards, regulations and equipment. The report also discusses the different work environment problems and hazards around military ARFF. Much of the information gathered for the report comes from interviews with personnel working in and with the military rescue services. The overall conclusion is that the basic conditions for a good ARFF tactic are there, but a lot needs to be improved and optimized..

Background: Anxiety with children before surgery is well known. From the 1950s there are various assessment instruments. Despite that most day surgery units offer preparation for children and parents, there are many children who exhibit a strong anxiety the day of surgery, which can lead to postoperative behavioral changes. Today the nurse estimates the anxiety of a child on personal experience and knowledge, forming the basis for estimation whether the child is in need of sedation or not. The purpose: of this study was to evaluate instruments that the nurse can use in measuring the degree of anxiety of children before fast clinical settings, such as day surgery.
