Temperaturens och den fotosyntetiskt aktiva strålningens effekt på avgång och inlagring av kol på en dikad torvjord

The decomposition of organic carbon in drained peat soils is a major source of carbon di-oxide in Sweden. A big part of these drained peat soils are used in agriculture and it is a big challenge to slow down their decomposition. It has earlier been thought that less tilling and higher water table levels would decrease the activity of soil microbes and thereby the decomposition, but recent experiments has showed that this has little or no effect. In this bachelor thesis a field experiment was made on drained peat soil with ley, outside Björklinge, Uppsala municipality, Sweden. The experiment was carried out in May 2011. The objective was to develop a method to examine how the net exchange of carbon diox-ide from plant covered peat soil is affected by temperature and photosynthetically active radiation (PAR).

Att skapa fria, demokratiska och solidariska medborgare : En essä om att granska våra normer

This essay is about power, democracy, solidarity and equality in preschool. I examine three different situations to determine if I could have acted more sensibly in my interactions with the children. I portray: a ?children?s choice meeting? where children select an activity, a so-called emotional gathering and a dialogue at the lunch table about a popular movie that we plan to watch together afterwards. The purpose of this essay is to examine which norms and values form the basis of my actions, and if so, how these lead me to use my power to shape the children.I have chosen to use hermeneutic and norm-critical perspectives where I investigate and examine my norms and values and how I react and act, both consciously and unconsciously.

Restvärmeåteranvändning från absorptionsvärmepumpar : en kartläggning av möjligheter och begränsningar vid Vattenfall Värme Uppsala Block 5

Vattenfall district Heating power plant in Uppsala produces district cooling with absorption heat pumps which leads to a large amount of waste heat that has to be cooled with evaporative cooling towers. The Environmental Court has ordered Vattenfall to survey the possibilities to recover the heat, which is the focus of this thesis.The study begins with an overview of the system, and conditions and limitations for waste heat recovery is examined. In the next step alternatives to recycle the heat is evaluated, either by direct recovering or by upgrading.First, the technical possibility of each alternative is discussed, and then the operation time and the amount of recovered heat is calculated. Those alternatives which are possible are brought further to an economic analysis.The cost of investment for each alternative constitutes the basis for a present value analysis. The results are put together in a table where the total amount of recovered heat is compared with the present value for the different alternatives.

?Torktumlarhuvuden? och ?teflonhjärnor?. : En fallstudie om det specialpedagogiska arbetet kring ADHD och dyslexi på tre gymnasieskolor i norra Sverige.

This case study examines how upper secondary schools in a municipality in the northern parts of Sweden structure their special pedagogy with students who have ADHD and dyslexia, students? and parents? experiences of this, and what regulates the schools management in this particular aspect. The results show that all the schools have special pedagogues and other support staff employed, though in varied extent. Furthermore, the resources are distributed differently from school to school. The focus, however, is always around communication between the concerned parties.

Spännkraft på bandavskrapare : Utredning och konstruktion

This thesis was performed at Vendig AB which is a company that develops and sells products such as belt scrapers for conveyor. The thesis is divided into two parts, one part where it´s investigated which tension force is required to tighten Vendig AB´s scraper Hampus against the belt in a correct way. The second part is called mechanical design and here a new and more compact tension device is developed.Field studies has been conducted at a couple of Vendig AB´s costumers to get a knowledge base about how Vendig AB´s products are used, how they function and the environment they operate in. During one of the field studies the force between the scraper and the belt was measured. The result from the measurements, together with a report from LKAB [1], were evaluated and summarized in a table.

Simulation environment for further development of distributed
milking products

För att underlätta vidareutvecklingen av dagens programvara har jag fortsatt att utveckla den simuleringsmiljö som redan finns på företaget idag för en av produkterna som används vid mjölkning. Simuleringsmiljön skall underlätta utvecklingen av större system för större gårdar. Det som systemet hjälper till med är just uppsättningen av en gård med ett visst antal kor och ett visst antal mjölkningsmaskiner. Den tidigare miljön var skriven i MFC men för att möta morgondagens krav har denna blivit omskriven till C# .NET med hjälp av Windows Forms. Det program jag skrev först använde sig av C++/CLI vilket var väldigt krångligt att använda, det resulterade i att jag helt och hållet gick över till C# .NET.

Ruttplanering : Retursystem för pantade PET-flaskor och aluminiumburkar

This report is the final part within our education, Industrial Organization and Economy focusing on Logistics and Management at Jönköping School of Engineering. The aim with this report is to coordinate recycle drives for deposited aluminum-cans and bottles collected from grocery stores within Jönköping county and locality.In the present situation both aluminum cans and bottles filled with drinks are distributed to the grocery stores by the brewery?s own distributers. At the same time as they supply the drinks they also discharge the grocery stores units with restored aluminumcans and bottles. To make it easier for the grocery stores to handle the goods in the future, all distribution of drinks ought to be directly delivered to the grocery stores own separate central warehouse.

Utredning av fastighetsel i ett äldre och ett ombyggt flerbostadshus i Gävle

The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..

Tjejgrupp - stärkande eller problematiskt kollektiv? : En analys av erfarenheter och minnen från feministiska tjejgrupper

This essay investigates the results of participation by teenage girls in feminist groups, the so called girl groups. These groups are descendants of the awareness-raising groups of the 1970?s feminist movement. The essay assumes the relevance of theories of heteronormativity and performativity, as well as theories surrounding two different ways to organize girl groups. It is done either through the Pippi-feminism, named after strong independent book character Pippi Longstocking, or through the collective empowerment feminism.
