Sjöingenjör : Möjligheternas Yrke
Kärnkraften ser vi som ett miljövänligt och bra alternativ för framtiden. Därför kändes det intressant att undersöka om vi som blivande sjöingenjörer har en framtid där efter våran karriär till sjöss. Syftet med detta arbete är att få ökad insikt om vilka teoretiska kunskaper, praktiska och personliga egenskaper som gör sjöingenjören attraktiv i ledande befattningar vid kärnkraftsverk. Datainsamlingen skedde med hjälp av en enkätundersökning och en intervju. Undersökningen skickades ut till Sveriges samtliga kärnkraftverk och intervjun gjordes med en anställd på ett utav dem.

Biogas till kraftvärme på Wapnö : en projektanalys utifrån ett företagsekonomiskt perspektiv
Biogas is a gaseous fuel, rich in methane, produced through a biological route in an anaerobic digester. A gas engine generates combined heat and power, which can be used at the farm to reduce energy cost. The process also generates a digestate, with better utilization of nutrient compared to cattle manure.
The aim of this study is to analyze the profitability of a farm-scale biogas plant for combined heat and power (CHP) at Wapnö. Wapnö is an agriculture company located in the southern part of Sweden.
Hästavmaskningsmedels påverkan på miljö och välfärd
Healthy, natural pastures is very valuable for biodiversity in the form of both plants and animals. An efficient use of pastures helps to preserve biodiversity, but grazing animals needs to be de-wormed to keep them healthy and to prevent harmful parasites spread on the pasture. The awareness about the environmental impact of the frequent use of deworming agents is low among the public. Some people are unaware that the absorption in horses of anthelmintics is incomplete, which make the circumstances about enviromental effect important to investigate further. The scientific evidence in this area is limited and more studies and trials are needed to deepen the knowledge about the effects of anthelmintics in the environment.
Balanserad samhällsbyggnad i Eslövs kommun : fördjupning av översiktsplanen för östra Eslöv
This work has been made in cooperation with the municipality of Eslöv and the inventory area is a part of the deepening of the municipality plan of east Eslöv. The aim of the work is to test the principle of balance in the overall planning. Later in the detailed planning process a more detailed calculation is made and a suggestion of suitable measures for compensation is made. Then the method with green area factors can be used. The goal is to balance the negative influence on the environment from the planned impacts to gain a sustainable development of the city.
The principle of balance means that the one responsible for the development also has to compensate for the negative impacts on nature and landscape that comes with the development.
Metodik för identifiering av T-stycke med risk för termisk utmattning
Thermal fatigue is a serious problem in todays power plants. A large amount of damages around the world circles around that subject. The damage can come from the mechanism of two flows mixing with different temperatures in a T-junction. It is a fundamental prerequisite that these T-junctions are frequently tested for damages. An amount of criterias steers the rate of testings.
Vindkraftverk av UHPC 2.2 : En undersökning av högpresterande betong med syntetfiberarmeringen STRUX
Användandet av betong som ersättare för stål vid produktionen av vindkraftverkstorn har ökat den senaste tiden. Betongtorn är betydligt billigare än ståltorn men problem som sprickbildningar, frostsprängningar och följaktligen armeringskorrosion har uppstått bl a på grund av vibrationer från rotorn. I fundamentet i vindkraftverk kan ovan nämnda problem också uppstå och det uppfyller således inte alltid funktionskraven. Det här examensarbetet undersöker möjligheten att eliminera dessa problem genom att använda en sorts högpresterande betong kallad UHPC 2.2 med syntetfiberarmeringen, STRUX. Jämförelser mellan tidigare empiri om högpresterande betong och laborativa tester på UHPC 2.2 visar att den senare är beständigare och ger möjligheter till en större sprickfrihet.
Improvement in agricultural production in a rural area of Cambodia between 2004 and 2011 - with an emphasis on small scale cattle production
Cambodia is located in Southeast Asia with a tropical monsoon climate and distinctive wet and dry seasons. Poverty is a widespread problem in Cambodia and 30 percent of the population were classified as poor in 2009. About 80 percent of the populations live in rural areas where poverty is an even greater problem. In agriculture, rice cultivation is dominating and the crop is cultivated on 85 percent of the arable land. Livestock keeping is also a traditional part of Cambodian agriculture.
Stenmuren i landskapet : bevarandet av ett kulturarv
The landscape with its associated historical tracks and remains are an important part of our cultural heritage that we consider important to conserve. The stone walls are an example of historical remains that helps to build up this cultural heritage. It is a landscape element that today usually is being associated with the old cultivated landscape, where they mainly functioned as boundary markings and fences. Today, the stone wall is a valuable element in the landscape with ecological, culture-historical and aesthetic values. Since the stone walls arose as elements in the landscape a lot has been changed within the agriculture.
Jämförelse mellan våtkompostering och andra VA-system i omvandlingsområden : en fallstudie i Norrtälje kommun.
Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.
Skillnader i vatten- och avloppshantering inom EU : En jämförelse mellan Slovakien och Sverige
The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).
Utvärdering av svensk vindkraft : Skillnaden mellan skogs- och traditionella placeringar
During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good..
Grovfodermajs : från odling till utfodring av växande nötkreatur
The use of forage maize has increased over the last years. The aim of this litterateur review was to summarize a part of the research that has been conducted on forage maize for growing cattle, including cultivation and conservation of the maize. The forage maize is planted in April or the beginning of May when the temperature in the soil is between 6 and 10°C. Maize needs high temperatures and much water. Maize is harvested in the autumn when the dry matter (DM) is more then 30% or the plants have been exposed to the first frost in the autumn.
Köpa jordbruksmark i Ukraina :
We have chosen to write our examination essay about Ukraine, we wanted to find out
what kind of possibilities there is to run a farm there, and also find out what kind of
problems that might arise. Ukraine is still heavily influenced by Russia and the legacy
from the former Soviet Union. The agriculture today looks pretty much like it did before
the collapse of the Soviet system. There are large governmental or cooperatively owned
farms. The large farms have to deal with bad cash-liquidity and they often have trouble
getting a hold of seed and artificial manure to their whole acreage.
