Kylning och torkning av ett högtryckskompressorinlopp
Examensarbetet utfördes på University of Florida vid Department of Mechanical and AerospaceEngineering i deras Energy and Gas Dynamics Systems Laboratory. Laboratoriet forskar på enny gasturbincykel som producerar kraft, värme, kyla och vatten. Cykeln är kallad High PressureRegenerative Turbine Engine (HPRTE) och kombinerat med gasturbincykeln är ettabsorptionskylsystem (VARS). Kylsystemet drivs av spillvärme från avgaser som cirkuleras igasturbinen, den producerade kylan används för att kyla ned högtryckskompressorinloppet.Syftet med det här examensarbetet är att undersöka möjligheten till att kyla ned inloppet tillkompressorn till temperaturer långt under fryspunkten för vattnet i den fuktiga gasen. Om gasenskall kylas till nivåer under fryspunkten måste vattnet föras bort från gasen.
Kamratkulturer - att tillhöra gemenskapen ur barns perspektiv (Peer cultures - to belong, children´s perspective)
Problemområde: Barn i förskolan delar en specifik kamratkultur som innehåller kunskaper och information om gruppens sociala vardagsliv. För att kunna bekräfta, förstå och respektera barns relationer behöver pedagoger analysera och agera utifrån barns perspektiv. Om man erkänner barn som kompetenta aktörer och barngruppen som en viktig tillgång för det pedagogiska arbetet, behöver alla som arbetar inom förskolan uppmärksamma det barnen själva bidrar med i verksamheten.
Syfte: Det övergripande syftet med studien är att undersöka hur barns erfarenheter, uppfattningar och förståelse av tillhörighet kan komma till uttryck i en specifik förskolegrupp. Avsikten är att identifiera hur kamratkulturen speglas ur barns perspektiv.
The diffusion of minimum tillage in agricultural China : a study of the factors influencing the farmers? choice of tillage system
The Chinese government´s aim to be self-sufficient in food production in combination with the increased food consumption in China has put high pressure on the productivity within the Chinese agricultural sector (He j et al, 2010). In order to increase the productivity, modernization and adoption of new farming techniques are essential. The opportunity to adopt and import foreign technology has lately been possible in China, as more authority and decision rights have been given to the individual farmers and the country has opened up for foreign trade (Zheng, 2012 & Fan, 1991).
A more open Chinese market enables new opportunities for foreign agricultural companies to expand their businesses by introducing their products to Chinese farmers. But to succeed with this strategy the Chinese farmers must be willing to adopt these, for them new innovations.
Minimum tillage is a tillage practice used worldwide that is suitable in northern China where drought and erosion are the main problems in the crop production (pers.com., Arvidsson, 2012).
Potential users? opinion of new innovations such as minimum tillage is closely related to adoption (Rogers, 2003).

The railway bridge is in operation and serves over 10,000 trains a year, everything from speed trains to freight trains. The bridge is built as a beam bridge, simply supported over a road.
In search for sustainable alternatives to lawns : connecting research and landscape design
A large part of Sweden?s green, urban landscape is covered by lawns. Approximately 80 000 ha of maintained grass lawns are part of public courtyards, schoolyards, parks, golf courses, sport fields and traffic environments. Beyond this figure, the lawn is also an essential element in most private villa-gardens. Lawns have become a universal phenomenon through the dispersion of landscape aesthetics from the Western world.
?minblogg.nu? ? en kvalitativ studie om bloggande utifrån ett individperspektiv
Abstract: This study is focused on blogging from the perspective of the individual. Weinvestigate why one uses the weblog format, functions on the blog that are seen to work asdriving forces, attitudes towards self-disclosure and anonymity on the weblog and how therelation between an online- and offline-identity is interpreted by the bloggers themselves, forexample to what extent it is possible to get to know the blogger by reading the weblog.Finally, we investigate the weblog-readers meaning to the blogger, as well as their possibleimpact on both his or her personal blog-content and the everyday-life.The empirical material consists of half-structured interviews via MSN Messengerwith nine informants, being bloggers found on the Swedish website bloggportalen.se. Thetheoretical framework behind the interview guide focuses on the identity concept, containingidentity theories in psychological and sociological perspectives, symbolic interactionismconcerning the concept of roles, as well as Bauman?s liquid theory on postmodern societytendencies. This material is further included in related previous research articles, derived fromboth international and Swedish databases.
Vårdberoende, behov av omvårdnad och insatser för äldre med regelbunden vård och omsorg ? del av SNAC-Blekinge, Vårdsystemdelen
Background: The relationship between advanced age, presence of illness and
impaired functioning is well known. A large proportion of the elderly
population has an extensive need of care and service and therefore need help
from municipal care.
Aging is a transition in life and also affects the person's identity and self
image, making the person particularly vulnerable and challenging everyday
safety. It is therefore of importance to gain knowledge about which factors at
individual and organizational level that support a person-centered nursing care
for the elderly so that caring responsibilities and staffing of nursing
personnel may be scheduled based on need. Aim: This study aimed at describing
dependency and care needs of elderly persons living in ordinary housing,
sheltered housing and nursing homes. Furthermore the study aimed at describing
how the dependency was related to the staffing of non-licensed and licensed
nursing staff in nursing homes.
Method: A descriptive and analytical quantitative method was used in the study.

Hållfasthetsegenskaper i gjutjärn : tensile properties of cast iron
In the last few years people have become more and more aware of how humanity is affecting the climate. In the direction of reducing the greenhouse gases is to design engines with higher tensile properties and reduced weight, in order to achieve lower fuel consumption and cleaner fuel incineration in today's truck engines.In order to achieve these requirements it?s necessary to increase the combustion pressure in the engine. This requires higher tensile properties and high thermal conductivity of the engine material. The department of Component Technology at the University of Jönköping in collaboration with Volvo Powertrain AB, Scania CV AB and DAROS Piston Rings AB has been commissioned to develop this material and to find knowledge of material properties used in truck engines and piston rings used for marine applications.The purpose with this work is to analyze the tensile properties of a series of cast iron, cast under different metallurgical conditions.Four different series of cast irons have been analyzed from four points of view, carbon concentration, nodularity, amount inoculation and cooling rate.After the tensile test all specimen data was analyzed in a mathematic calculation program called Matlab 2006a.
Främmande kulturer : En undersökning om hur Handelsbanken förbereder sina expatriaterinom interkulturell kommnunikation
Every plan and program decided on by an authority or municipality, where the environmental impact can be considerable, must be environmentally assessed according to Environmental Code, the Planning and Building Act (PBA) and the Regulation on Environmental Impact Assessment.The purpose of this study is to examine the Environmental Impact Assessment (EIA) for The Region Development Plan for the Stockholm Region, RUFS 2010. The plan was approved by at that time the Regional Planning Office (Regionplanekontoret), which procured the process by consultants. RUFS 2010 includes two merged plans ie. a regional Development Plan (RUP) and the Regional Spatial Plan for Stockholm. It was necessary to establish an environmental assessment of RUP, but not for the regional plan.
Metodik för fastställande av bärförmåga på befintliga betongkonstruktioner
Many buildings are now nearing the end of their service life. This applies to both the older houses from the 40's and 50's to the million project houses that did not prove to be as sustainable in the long run. Often there is a desire to extend the service lifetime, but to do that you need to make detailed inspections. The Folkets hus in Gävle is one of those buildings that is in need of renovation and to fulfill the new requirements that must be met in today's buildings. It is desired to make the buildings rentable space more attractive and to extend the building with two more floors.

Collaborative Product Development - - Case Study within the Swedish Automotive Industry
Problem: The relations between first and second tier suppliers within the automotive industry have changed drastically during recent years. Previously involving the supply of simple components, today the relation involves collaborative product development of complex subsystems. The situation is rather new for the actors, hence there are a number of problems that act as restraints for the collaboration. In order to come to terms with these problems, it is important to determine the underlying causes. Purpose: The purpose of this thesis is to make a survey of the main problems in the collaborative product development between first and second tier suppliers within the Swedish automotive industry.
Folkbibliotek i skärningspunkten: Gammalt möter nytt i Idea Stores i London.
The aim of this master thesis is to study how the development of a public library by means of ideas and methods from the private sector can be related to traditional core values. We base our study on institutional theory, which focuses on norms and values in an organisation, and new institutional theory, which focuses on how organisations are influenced by changes in the environment. We also use New Public Management with a market focus to analyze the implications of a development towards a more market oriented view.The method used is that of a case study of a new library concept, Idea Stores in London. Idea Stores are a number of new public libraries in Tower Hamlets developed from the results of a major opinion survey about libraries. The Idea Stores combine traditional library services with elements of adult education and lifelong learning in a partnership with local learning centres.
