The Goal with this Master of Science thesis is to expand the possible turbine efficiencymeasurements on an exhaust turbocharger. It was done as a part of the CICERO competencecentre. To feed the turbine with air a special flow rig has been used. Instead of loading theturbine by just restricting the compressor flow a docking system for an electrical dynamometer isdesigned to use the dynamometer as an additional loading source. By using an electricaldynamometer as loading device for the turbine, measurements are not depending on compressorperformance.A large part of the work consists in designing accessories for the dynamometer.

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

Piglet survival is of importance because it affects the farmer?s economy and the welfare of the pigs. There are several factors affecting piglet survival and they are often linked to each other. This paper will focus on how the behaviour of the sow can affect the growth and survival of the piglets and also possible causations of differences in maternal behaviour. Sows in intensive production systems have different possibilities to express their maternal behaviour than free ranging sows.

This paper describes a case study of the largest film production ever conducted in Scandinavia. The study aims at explaining the complex relationships in the network structure in which the project took place. Coordination of creative projects carried out in a network context, includes handling conflicting interest and contradictions. Creativity needs space and freedom while projects need structure and coordination, whereby controlling these projects becomes complex. Adding to the complexity, does the loose form of organization that the network structure represents, without any long term structure.

Eutrophication of the Baltic Sea is a serious problem. A major contributing factor is diffuse losses of phosphorus (P) from agricultural land in surrounding countries. In order to estimate P losses, environmental monitoring of small agriculture-dominated catchments is being carried out in most of these countries. Evaluation of the risk of P leaching to waters is usually based on chemical tests originally developed to quantify the amount of soil P available for plant production. The tests are performed in different ways in the different countries and a number of different extraction agents are in use.

?Death in the pot.? The Fruit and Vegetable Preserving industry in East Scania during the 20th century A Company History.

Actual production remains at two sites only. The aim of this study is to determine the reasons for this development. The companies included in the investigation are AB Bjäre industrier, Gustaf Bong AB, Kiviks Musterier AB, AB Ruuthsbo konservindustrier, Th.

This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable.The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations.Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas.

The world is currently facing a huge severe challenge in handling the issue of climate change. One of the ways to lower the green house gas emissions, which is seen as one of the main contributor to the climate crisis, is to use renewable technologies such as for example photovoltaic (PV) systems. PV-systems are also suitable for so called micro production, small scale energy production facilities, since it can be placed on practically any rooftop with the right solar conditions. In Sweden the usage of PV-systems has not yet gotten any wider spreading, even though the solar radiation conditions are very similar to countries that produce a lot of solar energy, as for example Germany. The aim of this paper is to describe non-adopter perceptions of PV-systems. The study holds a qualitative approach using deep interviews for data collection.

The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

This study is about the use of textbooks in teaching English as a second language and about teachers? attitudes and opinions of using textbooks during lessons. The aim of the study is to receive a deeper understanding of the use of textbooks in English teaching and to learn about why teachers choose whether to use the textbook approach or not. The study contains an analysis of the textbooks the teachers in our study used. The analysis shows the actual content and the types of texts together with the design and the structure of the textbooks.

This study compare if there is any differences between Fairtrade certified and uncertified coffee producers in Aceh Tengah, Indonesia. The aim was to compare the way the two groups of farmers produces their coffee and see if there were any differences between them, income, post harvest, production etc. During a visit in the district of Aceh Tengah, producers from both groups were given a questionnaire with questions about their farm and their production. The results of the questionnaires showed that the certified producers felt they had benefits being a part of a certified cooperative. Even with the experienced benefits the certified cooperatives gave the connected producers, like agronomy consultation and workshops the uncertified producers had a higher income from the coffee per hectare. This study also indicated that introduction and presence of Fairtrade and the connection to the world market Fairtrade brings with it, has gained the entire area, for example with more stabile coffee prices..

I en global marknad blir det allt mer viktigt fo?r svenska industrier att effektivisera sina produktionsprocesser genom sta?ndiga fo?rba?ttringar och en offensiv kvalitetsutveckling. Shiloh Industries i Olofstro?m vill o?ka sin konkurrenskraft genom att fullt ut implementera filosofin Lean Production i sin verksamhet och i enlighet med detta ska en helt ny produktionslayout tas fram. Studien syftar till att finna aspekter fo?r beaktning vid utformning av en produktionslayout som finner sto?d i Lean Production.

An ethnographic study loosely informed by the theoretical framework of distributed cognition was carried out in order to describe how mariners have adopted the Automatic Identification System (AIS) in their work practice, or"made the technology their own". AIS is a transponder-based identification and communication system that allows ships to automatically identify and track each other. In addition to facilitating the identification and tracking of ships, objectives behind the introduction of AIS are to"simplify informational exchange", and"provide additional information to assist situation awareness". Participant observation and interviews were made at four different ships, as well as at two shore stations. A focus group was also held at a maritime conference.

Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe chewing behaviour in growing cattle, as well as the factors that affect this behaviour.
