Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.

For Skattkärr IF a turf field with warming has been projected to increase field?s utilization hours and to have a longer period for athletes to perform their activities outdoors. The technique chosen to heat the plan is a type of a geothermal heating system without a heat pump. The brine, which is water with 30% ethanol, collects heat from the borehole and discharges it to a coil in the field. There is at position 11 boreholes but it is planned to increase the number to 31, which is the design for the facility.

The purpose of this study was to illustrate how professionals, who work with psychosocialproblems among children, look at the impact of social factors on behavior that causes ADHDdiagnosis and at the relationship between social factors and the increased diagnosis that hasoccurred in recent years. To answer our purpose, we chose a qualitative approach byinterviewing six professionals who had different professional affiliations. We analyzed theresults using systems theory and attachment theory. The results showed that the professionalssaw various social factors that influenced the behaviors that cause ADHD diagnosis, particularlytroublesome growing environment and the school environment that requires greater cognitiveability and social skills of children today. They also saw that social factors could have an impacton the increase of diagnoses, particularly that the diagnosis can result in that the understandingchanges and that it is considered easier to get extra support at school with a diagnosis..

Skärgårdsstiftelsen, which is responsible for several of the archipelago islands in Stockholm, has chosen to explore the possibilities for more sustainable heating systems in buildings on the islands in collaboration with KTH. A reduction of energy use and improving the efficiency of existing heating systems are included as part of the environmental work. This report studies the island of Grinda, which is located outside the area of Vaxholm in Stockholm. The study area consists of a guesthouse consisting of a restaurant as well as conference facilities and four neighboring cottages used for overnighting. The cottages now run solely on direct electricity, both for heating and hot water.

The background for my thesis is the fact that with rising electricity and oil prices it becomes interesting to calculate on alternative heating systems. I have chosen to calculate upon my parents? farm, which today heats the dwelling house with wood. This is very time-consuming work, time which could be spent on other work. The main objective for this study is to compare three different heating systems to decide how they differ considering effort and cost. The result from the calculations was that grain-heating system demanded the least amount of work, but the total cost was a little higher compared to chips heating. Chips heating required half as much work as today?s wood heating and had a little lower total costs compared with the corn heating. Which system to choose largely depends on how the own work is valued.

Holmen Skog is currently using a GPS-program called TraktInfo, originally developed within the company. They are now planning to switch to a new GPSprogram or allowing the contractors to buy other programs available from the logging equipment manufacturers. To be able to offer this flexibility, Holmen Skog needs to obtain information about the features offered by the different manufacturers in their specific programs, and also when the manufacturers are planning to start selling programs adapted to the new standard called StanFord2010. According to the study, the manufacturers are hesitant to StanFord2010 and there has also been a lack of clear signals from the customers and clients about what kind of different new features to include in the programs. The feature most frequently used by forest machine operators today is the option to keep record of the harvester?s path by creating a ?log plot?. This feature was not used to its full potential however, since only one out of eight of the forwarders included in the study had computers that were compatible with the harvester?s computer.

District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.

Most often when developing a new system there is a need get a functioning testtool up and running. Including time, cost and resources the solution isn?t always obvious, developing your own or buy one ?of the shelf?. The purpose of this thesis is to study how a general testtool for executing functional tests should be designed to be reusable, be based on recognized knowledge and be able to fast and simple be customized for different types of systems. Key functions from the litterature is presented and used in the design of a testtool prototype.

The main purpose of this study was to examine if, and how, persons with psychological impairments have worse living conditions than the population average. The papers intention was to investigate and describe these conditions and to analyze them based on theories of stigma, and systems theory. This paper was composed on a qualitative study in which god men have been interviewed, in addition to accomplish the purpose. This study has highlighted the four individual areas of economy, employment, housing conditions and social relations. Results have shown that people with mental disabilities tend to live in worse living conditions than the population average.

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

Banverket Trafik has a responsibility to make sure that the companies who traffic the Swedish railroad have the correct information about the status of the railroad. One of Banverket Trafiks information systems (Opera) presents the train?s actual position on a map and provides the user with physical information about the trains. Due to increasing demands on the information systems, Banverket Trafik needs to update the present system architecture in order to manage the increasing demands on map graphics and map functions. This paper analysis the information system Opera on the basis of theory and support of methods and discuss problems and demands for Opera.

Jönköping's municipality requested a diploma work witch would present the experiences, as arisen during the existence of the echo village Smeden.To recive information for the background, literature at the university library were searched at the database "Libris" with words like "echo village" and "ecological living".Data was retrieved from 28 questionnaires that were sent out to the inhabitants of the echo village Smeden. The questionnaires contained questions about experiences, opinions, ideas and thoughts about living in this echo village. The results were analyzed and presented by diagrams and tables and showed that the inhabitants where most unsatisfied with the sewer and the system of the toilet. In the opposite the inhabitants experienced that the remaining systems were in satisfactory and the majority of the inhabitants were very pleased with their living conditions.Conclusions of this study are that an echo village would be a suitable alternative to an ordinary living and that ecological living would be something that would work well even in the future. An important thing to remember is that the systems of the households must be easy for the inhabitants to maintain otherwise the environmental thinking would be in risk of failure if some don?t have the energy to manage this properly..

In Sweden, there has been a continuous increase in the volume of housing construction for dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.

The term maneuver warfare is frequently used in western defense doctrines and theoreticaltextbooks. The ambition of the Swedish armed forces is to attempt maneuver warfare in allappropriate situations. Theories and doctrines indicate the importance of decentralized command and control systems. Mission command (Auftragstaktik) is one such system and should be applied to all situations of the Swedish Armed Forces. There are theoretical and doctrinal bases for warfare and command, but in practice, what are the preconditions for this? Previous research addresses many theoretical questions but there are flaws in existing studies investigating practical realities.The purpose of this study has been to reach a deeper understanding of armed forces ability to maneuver warfare by analyzing conformity of command and leadership perspectives in practice.This is an interview-based qualitative case study in which respondent´s statements were analyzed and interpreted in relation to a theoretical framework.

In Sweden we have a regulated gambling market which means that there are three gambling companies who are operating under the supervision of the Swedish state. These companies have exclusive rights to the Swedish market, divided between them. AB Svenska Spel is one of them and they control all gambling concerning sporting events and the four casinos in Stockholm, Gothenburg, Malmö and Sundsvall. However, since a few years back several Internet-based companies have entered the Swedish market and the competition has become even fiercer in the last years. Due to numerous marketing restrictions the Internet companies have been forced to find new ways to strengthen their brand.
