Studie av skyddsavstånd mellan bergvärmeanläggning och skyddsobjekt i ett vattenskyddsområde
During installation and operation of a geothermal heat pump system leakage of an antifreezing agent can appear in a borehole and leak out in surrounding groundwater. To guarantee high quality drinking water for generations to come Sweden has dedicated some areas as water protection areas. The local authority gives permits for the installation of heat pump systems within water protection areas. Before giving a permit the local authority makes an evaluation of the risks involved in installation and operation of the system within the area. By keeping a certain distance between the protected object in the area and the heat pump system the risk of polluting the protected object with an anti-freezing agent can be reduced.This thesis makes a comparison between three different methods of calculating an appropriate distance between the protected object and the heat pump system.
Energieffektivitet och kvalitet på inomhusluft i radon förorenade bostadshus
To build a sustainable future should we first understand that; every aspect of our daily lives can affect the environment. It?s important that we take responsibility for understanding how we impact the environment and change our actions accordingly. The worlds total energy consumption equivalent to 80 million MWh / year. This corresponds to about 220 million MWh / day.Energy consumption is one of the main reasons for increased greenhouse gases when the reduction of this consumption has a great demand worldwide.In order to prevent the energy that consumed the buildings must be energy efficient but there is a conflict between radon ventilation and energy conservation in a building, given that ventilation can consume as much energy (currently 29-59% of energy-efficient houses use), especially in a cold climate as in Norway.
Miljögifters exponering, ackumulering och effekter på immunsystemet hos husdjur :
The purpose of this literature review was to describe the paths of exposure and accumulation of organic pollutants into the tissues of farm animals. Organic pollutants can be spread in the environment by air and rainwater. Farm animals can be exposed to these pollutants for example by eating soil or contaminated plants. Many of the pollutants can then accumulate in the fat tissues of the body because of their lipophilic character. Brominated flame retardants and perfluorolated compounds are both pollutants of current interest.
Transientanalys för Forsmark block 2 och 3 : Studie av hur val av driftpunkt och pumpreglering påverkar torrkokningsgränsvärdet
The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.
Ägarlägenhetsförrättningar ur ett kostnadsperspektiv : Hur utvalda faktorer påverkar förrättningskostnaden och den framtida förvaltningen
The purpose of this study is to get the cadastral procedure for condominiums to become more affordable. The aims of the study is to examine how the number of condominiums, the number of joint facilities and the number of joint property units that are formed in a condominium cadastral procedure in Sweden influences the cadastral procedure cost. To get an overall perspective the study also explores how the chosen forms of co-operation have worked out in association management.A condominium is a type of three-dimensional property unit, which may only contain one residence. This form of property formation has been allowed in Sweden since 1 May 2009. At the end of 2014 less than 1000 condominiums had been formed despite the legislator?s expectations for 3000-5000 condominiums a year. The property unit can have access to necessary facilities, not available within the property boundaries, by establishing joint facilities or form joint property units.
Föräldrars upplevelse av miljön och bemötandet på Ronald McDonald Hus - en kvalitativ intervjustudie
Abstract Background: Families with sick children are expressing the needs of accommodation near the hospital, in order to be close to their children and be together as a family.Aim: To investigate how parents experienced the hospitality and the environment at the Ronald McDonald House (RMH) in Uppsala and how they feel their children have experienced the stay.Method: Descriptive qualitative interview study. Five parents who lived with their family at RMH between 2013- 2014 have been interviewed with a semi-structured approach. A qualitative content analysis with an inductive approach according to Graneheim and Lundman (2003) was conducted on a manifest level.Results: RMH made the families? situation easier. RMH met their needs of a homelike environment where they could be themselves; be together and maintain everyday routines.
Effekter av urbanisering på grönalgen trädgröna i Linköpings stad med omnejd. : Biologiundervisning i närmiljön
Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.
Parkplan för Kungälv med förutsättningar för sociala värden :
To work with environments outdoors for people, animals and plants is the main topic for the landscapearchitect.
On several occasions the work is about public places that is to be in relation with other parts of the town. It is about the activities and the life that take place.
The physical environment and the interpretation of it gives possibilities or obstructions
for people who moves around or spend time in it.Since public places, parks and places for movement are used in daily life they strongly effect the people who use the places. The concequences of this effect can be positive or negative experiences.A positive example is a passage over a brook on the way to school while a negative one is to be afraid while passing a tunnel when it is dark outside. Other examples of concequences are stress effect from traffic noice or calming environments with twitter of birds.
The physical environment is also a part of the total interpretation of a town.
Hållbara projekteringsverktyg : Från byggnadsinformationsmodell till simulering ? en utvärdering av Revit och Virtual Environment
This study examines the use of building modeling and energy simulations in the design process of a building. The take-off point is the notion of energy simulations being needed early and throughout the building design process, and that the lack of energy simulations may be explained by the fact that they are time consuming and therefore often too expensive. A greater interoperability between software tools used by relevant disciplines, such as the architect and the energy specialist, would create smoother workflows, which would reduce this cost and open up for more frequent and iterative energy simulation processes. The study is an assessment of the modeling tool Revit and the simulation tool Virtual Environment and whether they can create smoother workflows, and make leeway for a more frequent use of energy simulations throughout the design process. It also investigates the limitations of what can be examined by simulations in Virtual Environment. This will hopefully help clarify the future role of energy simulations in design processes. The method is a trial by error approach of testing the two software tools by building and simulating a model. The results of these tests show that the workflow is not optimal (and therefore time consuming) for frequent and iterative simulations throughout the design process, but it also reveals some great possibilities of what can be performed with these two powerful tools at hand. Further development with regards on platform independency of the building information model, including seamless exporting and importing, seems necessary to strengthen the future role of energy simulations..
Hur spinalbedövade patienter erfar den intraoperativa fasen
Patienter som genomgår en operation har normalt ingen kontakt med varken operationssjuksköterska eller en anestesisjuksköterska innan ingreppet. En första kontakt sker oftast när patienter anländer till operationsavdelningen, då är tiden knapp och gör det svårt att tillsammans med patienter planera vården. En perioperativsjuksköterska har ett etiskt ansvar att bjuda in patienter till en vårdande gemenskap och skapa förtroende genom sina möten med patienter, vilket bäst kan göras genom ett perioperativt samtal någon dag innan operationen. Idag ges sällan den möjligheten.Det finns få studier gjorda om hur spinalbedövade patienter upplever tiden under sin operation. Därför riktas uppmärksamheten i denna studie mot hur spinalbedövade patienter erfar den intraoperativa fasen.
?Utredning av fosfatets inverkan vid pressning av rullar i LRQ MEDIUM BEARINGS
Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.
Funktioner och roller i skolbiblioteket ? En studie av två F-6-skolor i Växjö
The purpose with this study is to examine school-leaders?, school-librarians? and teachers? expectations and aims for their school-libraries at two different schools in the city of Växjö. The study is based on these five questions:· How do school-leaders, school-librarians and teachers think about learning?· What function does the school-library have?· What roles do school-leaders, school-librarians and teachers have in the school-library?· How do school-leaders, school-librarians and teachers experience the co-operation in the school-library?· How would school-leaders, school-librarians and teachers wish that the co-operation should be?To be able to answer these questions I have done thirteen qualitative interviews and studied literature relevant to the subject. Three different theories are used as a theoretical framework; the traditional perspective, individual constructivism and social constructivism.

Skolhuset - idéer, avsikter och debatter kring skolhusets fysiska miljö i tidskriften Lärarnas Tidning - Svensk Skoltidning 1962-1974
In this study I examine the debates, intentions and ideas concerning the physical and created schoolroom as they appeared in the journal Lärarnas Tidning - Svensk Skoltidning (Teachers Journal ? Swedish School journal) during the period 1962-1974. The built and created school building and its environment has been a relatively neglected topic in Swedish pedagogical research.When the Swedish comprehensive system transformed during the sixties, with new curricula and a common nine year school, many school professionals realised the need for a new and pedagogically adjusted schoolhouse.The early seventies marked a decline after a ten year period with an extensive building program affecting large parts of Sweden, and where schoolhouses had been an important part. The debate concerning the new Swedish school building was sometimes inspired and refreshing, but resistance and bitterness was also expressed. In part, this should be seen against the backdrop of the introduction of a new educational system, using new and sometimes untested pedagogical ideas, together with the fast transformation of the Swedish society.The research method is an exploratory textual analysis focused on five different issues: ideas concerning community centres and integration, participatory and democratic issues about the built environment, the school building as a pedagogical tool, aesthetic considerations, and the working environment.
Evenemang : Great event of Karlstad & Mariebergsskogen
In my study I have chosen to examine the mathematics in children's free play and everyday situations, with focus on sorting and classification. The purpose of the study was to see how children express their mathematical knowledge. I have chosen to use a qualitative method in my examination, here I did observations in a children's group where the children were between three and six years old. I also did interviews with the teacher's on the department to see how they relate to the mathematics and how they formulate the department to achieve as good a learning environment as possible.The result shows that the teacher's approach is incredible important to the children's learning ability and that they are always present to challenge and discuss together with the children. The observation indicates that children use mathematics all the time in their everyday situations and that it is the interaction between individuals and environment that affects children's development. .
