Skogsbränslets fraktionsfördelning
This study has analyzed particel size distribution and needle content in chipped logging residuals (branches and tops) delivered to the district heating plant Ryaverket in city of Borås, Sweden. Two fuel assortments has been analyzed: Chipped logging residuals from pure softwood and from mixed fuel (connifers and broadleaves). The samples has been sieved at Linneaus University laboratory.The study of particle sizes indicates that only 53,2 % of delivered fuel is within the fuels specification (7? 45 mm). The needle content is in this study 12,4 % (dry mass) which is higher than expected..
?Att sätta barnen före sig själv?? : En argumentationsanalys på Tingsrättens avgöranden i mål om vårdnad
The aim of this study was to examine the District Court´s argumentations about the children´s best interests in rulings regarding custody of children, and to analyse the argumentation from a gender perspective. Rulings from the District Court from 2012 have been the basis for this study and a qualitative method has been used, argumentations analysis. The study shows that cooperative problems between the parents are the main reason why the District Court finds joint custody to be excluded. There are also argumentation regarding parent´s ability to ensure the children?s safety.
Low Temperature Waste Heat Solutions : with proposals for energy technological actions based on Scania?s building 64
The report comprises two separate parts:part 1: Temperature needs for district heating in the paint shop for axles in building 210part 2: Energy and low temperature waste heat solutions in heating and cooling systems for building 64 with surroundingsThe paint shop for axles in part 1 has air quality requirements in places for coating of axles. Toachieve desired air properties there are different process ventilation systems, which consist ofventilation coils for heating and cooling, plus air humidifier. The ventilations coils for heating usedistrict heating. Today the ventilation coils use water of 100°C to achieve necessary air demands inthe coating boxes. This part of the report investigates whether the existing system would achievethe air requirements with a water temperature of 75°C instead of 100°C in the ventilation coilsduring the coldest parts of the year.
Rosengårdens Barn och Den Svenska Kulturen
This dissertation is about children in a district in Malmö, Sweden that is called Rosengård. This district is known for its high amount of immigrants and foreigners and all the children interviewed for the study are foreigners.We wanted to bring out their story, how they experience the cultures they are in touch with, the Swedish culture that they live in and their foreign culture that they experience at home with their parents. How do these children socialize into the Swedish culture while living in a district that is hardly exposed to it? We have been working from a different perspective, this due to the fact that we have both grown up in Rosengård and are still currently living here. Therefore our perspective is more from the inside, we can relate to the children?s stories and we can tell about it in a way that seems more natural.These children are not more different than other children, they have the same interests and hobbies as is considered to be ?fashionable? in youth culture today.
Kartläggning av energianvändning under byggfasen vid nyproduktion av flerbostadshus
The energy consumption in the sectors of residential and public buildings is 40 % of the total energy consumption in Sweden. The main part, 85 %, of the energy use in these sectors is for operation of the buildings. The rest is used in the building process. When energy-efficiency measures are taken the energy use during the operation time decreases and the fraction of energy consumption during the building time increases. This project is carried out in cooperation with JM AB and concerns the energy use during the building time of production of blocks of flats at the building site.The main part of the electricity that is used during the production of apartment buildings goes into the heating of portacabins and illumination of the building during the construction phase.
Vad skulle få en lantbrukare att ställa om från konventionell till ekologisk mjölkproduktion? :
The Swedish government has proposed that 20 % of the cultivated land in Sweden should be organic by the year 2010 (The Swedish Board of Agriculture, 2008). In addition to this the production of organic food like milk, meat and egg should increase considerably. To reach the government?s goal it is necessary that the Swedish farmers get motivated to convert their production from conventional to organic. Milko is a dairy association that has chosen to focus on organic products, they want to be the leading organic dairy association, and therefore they have a large need for organic milk (Milko, 2008).
Traditional milk production in cattle in a semi-arid area in Kenya
Livestock of pastoralists provide meat, milk, blood, dung and are useful for transportation purposes. In semi-arid and arid areas with very low precipitation the herder must often walk far distances to feed the livestock. This affects the animals? production, especially of milk. Previous studies have investigated how to improve milk production in terms of milking strategies in cattle.
Kunskapssyn och behov av IKT - verktyg
The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

Tjäna pengar som gräs? :
The producers of grain in Sweden are facing a rough future. The competition is getting harder all the time, in Sweden, in EU and also from the ?world market?. The producers have to be more efficient and have to have bigger units. Many producers might have to look for new alternative production opportunities.

Analys av energiförbrukning, Akzo Nobel Functional Chemicals AB
The main purpose of this project was to make a survey of the steam and electricity consumption at Akzo Nobel Functional Chemistry AB and give suggestions of how to minimize them. These three different areas were focused on. First to make a survey of all the most important consumers, second to find the electricity consumption of the air compressors and the amount of waste heat produced from them. The third area was to calculate a model of how much fresh water that is used during a cooling sequence in the water based heating/cooling system of the reactors and give a suggestion of a suitable reuse for this water.The main result is a total survey of the energy consumption in steam and electricity. The survey shows that the second largest group after drying is heating of ventilation which gives big potentials of reducing the total steam consumption if there is a way of being self supporting in ventilation heat.

Gårdsbaserad biogas på Nya Skottorp : utvärdering och optimering av anläggningen och uppgradering av biogasen
Biogas is an expanding sector within the broad field of agriculture and animal production. Small-scale biogas offers local combined power and heating production and the substrate is transformed into high-quality biological fertilizer. This bachelor thesis focuses on a pig farm in south-western Sweden, where biogas is produced from pig manure, evaluates and suggests ways of optimizing the process and investigates whether investing in an upgrading plant would be a feasible and more cost-efficient option. The results show that the biogas plant is working well, although the production differs from the original plans. This shows in turn that planning and examining the basic conditions before making the investment is of great importance, as well as monitoring and keeping detailed statistics of the running process.
