The purpose of this project is to analyze and study the absorption of the substances ivermectin, spinosad and barettin to hydrophobic and hydrophilic surfaces, and to analyze and study if the barnacle larva are effected when they try to settle on the treated surface.Incubation tests with barnacle larva in Petri dishes were performed as well as absorption tests on hydrophobic and hydrophilic surfaces which were tested with ellipsometry. To determine the surface thickness.The barnacles were placed in hydrophobic as well as hydrophilic Petri dishes that had been incubated with ivermectin, spinosad or barettin. After four to six days the larva was counted to analyze the settling. From the results conclusions could be drawn about the adsorption abilities of the substances to the different surfaces.The barnacles were placed in hydrophobic as well as hydrophilic Petri dishes that had been incubated with ivermectin, spinosad or barettin. After four to six days the larva was counted to analyze the settling.

Horses are made to eat mainly roughage and it is essential for optimal health to offer them an appropriate amount of roughage with good hygienic and nutritional qualities. To produce good hay at the right time and be able to keep the hygienic quality until next summer is a problem. This has the effect that horse owners today choose haylage and silage to a larger extent. Science in this area is scarce, i.e. if the change from hay to silage has any effect on the horse.

The purpose of this study was to investigate women's experiences of pain, bleeding,to discover the fetus, hospitalization associated with medical abortion at home and toexplore differences in experiences between different groups of women, as age orprevious childbirth. The study was conducted at two gynecological clinics in Uppsalaand in Stockholm. A questionnaire was distributed and analyzed using a quantitativeanalysis method. The response rate was 30 %. Most women were satisfied with thepain relief given to them from the hospital.

Energy efficiency is important both to reduce costs and to reduce greenhouse gas emissions in the atmosphere. Reducing costs will also help maintain business competitiveness.Scania in Södertälje is a company where the optimization of energy use is an ongoing and continual process. One area with potential to make energy and cost savings is the effectiveness of the ventilation systems in offices and industrial premises at Scania. During the summer months an increased demand for cooling occurs, leading to increased ventilation and a peak in district cooling system usage. Sorptive cooling is a technology where the supplied air is cooled by applying external heat.

Barren rearing environment and early weaning of piglets can lead to a high level of distress, behavioural disturbances and reduction in weight gain. The main aim of this thesis was to study the effects of potential enrichment objects on piglet?s behaviour and weight gain during the pre- and post-weaning period. The second aim was to examine what type of object stimulated the highest frequency of interaction. The study was carried out at the Swedish Livestock Research Centre in Lövsta where a batch of litters from 10 first-parity Yorkshire sows were used.

This study examines the differences between Bosnia and Herzegovina?s, Montenegro?s and Croatia's tourism development after the Civil War in the 1990s. In particular, this essay is about the town Neum, which is the only Bosnia and Herzegovina destination on the Adriatic, splitting the Croatian coast in two. Through information from books, the internet and interviews I´ve tried to find out why Neum is a special place to visit and how it differs from other destinations on the Adriatic coast. One of the findings is that many are not aware of Bosnia and Herzegovina having a small, but still, part of the Adriatic.

Käppala wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic wastes such as restaurant waste and waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

The purpose of this study is to examine what pupils in the ninth grade eats for lunch and also whether there is any connection between their lunch habits and perceived ability to concentrate and fatigue. A further aim was to study pupils' experience of dining environment in schools.The study is based on a quantitative method with questionnaires. The study was implemented on four schools in elementary school in themunicipalityofKristianstadand Tanum.Our results demonstrate, in accordance with several previous studies conducted in the same age group, that it is about half of the pupils who eats school lunch every day and that the majority are eating school lunch 3-5 days a week. Furthermore, our study shows that the pupils who rarely eat vegetables in school feel tired and distracted to a greater extent than the group of pupils who eat vegetables almost daily. Our result also shows that the group of pupils who eat the main course 3-5 days a week feel both tired and distracted to a greater extent than the group of students who eat the main course more rarely.In accordance with previous studies our study shows that differences exist between boys and girls regarding food that is eaten instead of school lunch.

Research concerning movement patterns of wild animals has been advancing since GPS technology arrived. But studying the snow leopard (Panthera uncia) is still difficult because of the harsh territory it inhabits in Central Asia. This study took place in south Gobi, Mongolia, and aimed to estimate the time spent at kills and the maximum distance away from kills between visits. Snow leopards were monitored with GPS collars that took a location every five or seven hours. Potential kill sites were established by identifying clusters of GPS-locations in ArcGIS and visited in the field for confirmation.

Immune-mediated haemolytic anaemia (IMHA) is an immune-mediated destruction of erythrocytes and is one of the most common haematological diseases diagnosed in dogs. The haemolysis is a type II immunoreaction and is initiated by IgG or IgM antibodies or complements. This retrospective study includes 63 dogs suffering from primary IMHA. The study was based on information from records from the Swedish University of Agricultural Sciences, Department of Small Animal Clinical Sciences in Uppsala and from the Animal Hospital in Strömsholm. The aim of the study was to evaluate the progress of the disease, treatment and the prognostic factors in different breeds, gender and age. Following criteria were used for the dogs to be allowed in the study: the dogs were diagnosed with anaemia, the anaemia was regenerative and autoagglutination and/or spherocytes were seen in the blood. About 50 % of the dogs in the study were diagnosed with IMHA within 2-6 years of age. Wire-haired dachshund was remarkably one of the most common breeds in this study together with Cocker and Springer spaniel.

The demand for district heating is expected to decrease in the future, due to competition from heat pumps and energy efficiency measures in buildings. Development of existing district heating systems is therefore necessary for district heating companies to maintain market shares. This Master?s thesis describes and investigates the heat and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is utilizing heat from waste incineration. In Sweden waste constitute 20 % of the fuel mix used in district heating systems, and this share is expected to increase in the future.

Being able to predict the future had been an invaluable competitive advantage for any corporation. Forecasting is a vital part of any business, hence a good forecast allows enterprises to invest in a beneficial way. However, there are several ways to prepare forecasts and the forecast methodology can vary. An industry that is dependent on forecasts is the energy industry. By predicting consumers' energy consumption, Swedish energy companies can hedge on the Nordic power market Nord Pool.

Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials. In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.
