There are many different recommendations on how to keep pelargoniums over winter, but most of the recommendations suggest ?the higher the temperature, the more light and water the pelargonium needs?. The purpose with this paper is to try to explain the best and the worst results that are achieved with different storage alternatives of zonal pelargoniums. The results are based on an orientating investigation carried out in January-February, and a questionnaire that members of the Swedish Pelargonium Society answered to. Both the orientating investigation and the questionnaire showed that zonal pelargoniums are best stored light and cold but frost free. They should be irrigated according to their needs which is when the soil is dry, about every second to third week. Zonal pelargoniums are very resistant to drought and can survive without water for at least 44 days, both when kept under light and cold as well as under light and warm.

I?ve tried to find the most effective and cost effective way to harvest straw for energy recovery.You can choose between round bales and big square bales. Square bales are the cheapest way to produce straw for fuel recovery because you can optimize the length of the bales so they fit the transportation equipment.In the Malmö area the average days of harvesting hay is 55. The effectively of transportation depends mostly of the speed, the distance and density of the bales. To increase the capacity of bale transportation larger loads and higher density of the bales is necessary.

In this Masters thesis we investigate query expansion using an electronic thesaurus. We formed 30 topics from the library and information science field. For each topic three searches were made in the bibliographic database LISA Library and Information Science Abstracts via CSA Cambridge Scientific Abstracts. LISA has an electronic thesaurus attached. We used this thesaurus to form baseline queries, baseline queries expanded with synonyms, and baseline queries expanded with both synonyms and related terms.

Sweden has distinct seasons with cold winter and temperatures down to minus 25 ?C andpleasant summers with temperatures above 20 ?C. During spring and autumn there could becomechallenges with precipitation. The diverse climate in Sweden affects many homeowners. For thepeople living in leisure boats and permanent housing boats the seasonal changes are clearlyimpacting their economy and the indoor climate.

Serpula lacrymans infestation has become an increasingly common problem, and is usually perceived as a tip of an iceberg.During the 21st century there has been a perceived increase of damage caused by serpula lacrymans, at AB Mats Fransson Saneringstjänst ? Anticimex in the county of Kronoberg. A similar increase has also been noted by employees at the offices in Kalmar, Karlstad, Piteå, Stockholm, Malmö, Söderhamn, Halmstad and Visby.The methods used to collect data for the project has been interviews with a number, for the project, relevant key persons, such as analysis engineers at Trygghansa and Anticimex, as well as personnel at the botanical institution at Gothenburg University and the Botaniska Analysgruppen in Gothenburg, further statistics from SMHI and analyses of reported instances of infestations have been used.The majority of the people interviewed believe that the increase is caused by renovations of old houses, higher precipitation during the summer months, as well as a moister climate and warmer winters. The latter can also be gleaned from statistics from SMHI concerning temperature, precipitation, and relative humidity.Analysed damage reports show that the most common cause for the infestation is ground moisture, even when combined wooden materials.Older houses that where built around 1900 are the ones most frequently infested with serpula lacrymans. The part of the building most frequently infested is the foundation, where cellars and suspended foundation are the most common types to be infested.

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

The purpose of this paper is to create an understanding of the negotiation process behind the decision of who will stay at home with a sick child and to develop the knowledge of the mechanisms considered to affect the negotiation process, in particular, the mechanisms likely to contribute to an uneven use of care leave. In the study six interviews were conducted with three sets of parents. These interviews were then analysed with Janet Finch?s (1989) definition of negotiation of family responsibilities. The study finds that the negotiation on care leave is a result of the negotiation of the shared view of reality.

The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background. This study shows that the dog ERG has both ON- and OFF-responses and that these responses can be separated by prolonging the flash duration over 50 ms. The dog OFF-response waveform was more similar to the cat OFF-response than the human OFF-response (Frishman, 2006; Zrenner and Gouras, 1979). In this study six female three-year-old Beagle dogs were included. Both background and flash stimuli were provided by LEDs (light emitting diodes) with a wavelength of 470 nm, a wavelength that is absorbed almost as effectively by the canine M/L-cones as by the S-cones. These stimuli gave ERGs with both ON- and OFF-responses.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.

The aim of this masters thesis is to examine query expansion. Query expansion is the process of adding new terms to a query to improve the retrieval effectiveness. In this study the baseline query was expanded in five different modes. The first expansion strategy was formulated by the inflected terms as the system does not allow truncation, I have inflected the terms, e. g.

Alzheimer's disease is the most common form of dementia. The individual who fall ill can be in an age between 40-65 years old. When dementia affects individuals at this age, many relatives take their responsibility for taking care of them at home for a long time.The aim of this study was to illustrate emotions relatives experienced when a close family member's suffering from Alzheimer's disease. The study was intended to show relatives emotions, and therefor four self-biographies were chosen to read. The method used to analyze was a narrative literature review.

Arbetet berör problematiken om hur fasadvegetation påverkar den relativa fuktigheten intill fasaden. Examensarbetet berör ett ämne som idag är väl debatterat men debatterna bygger i stor utsträckning på antagande och enskilda företeelse. Arbetet visar exempel på att det finns en allmänuppfattning om att murgröna försämrar konditionen på fasaden. I arbetet belyses även den litteratur som finns i ämnet idag. Litteraturen kompletteras även av studier och rapporter som är utförda inom området. Examensarbetet fokuserar runt den huvudsakliga frågeställningen om den relativa fuktigheten skiljer sig vid fasader beklädda med murgröna jämnfört med de fasader som är fria från vegetation.

Växthus används för att ge ett bättre odlingsklimat åt grödor och växter. För ytterligare förbättring av förhållandena används växthusvävar som exempelvis kan reglera temperatur, fuktighet och ljustillförsel. Väven som behandlas i denna rapport är en så kallad energiväv som främst har till uppgift att minska energiåtgången vid uppvärmning.När väven är fördragen nattetid, ökar luftfuktigheten då grödorna avger fukt dygnet runt. Fukten kan kondenseras mot energiväven, vilket gör att det bildas droppar på väven som kan falla ned på växtligheten. Den höga luftfuktigheten kan medföra svampsjukdomar och i övrigt också bidra till att tillväxten avstannar.

Today the individual ventilated cage system (IVC-system) is a commonly used housing system for mice in research facilities. IVC systems have HEPA- filters and are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare of breeding females and pups of two different strains of laboratory mice (NMRI nude mice and C57BL/6N) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. The NMRI nude (Nu) females gave birth to 18 litters in Allentown, 16 litters in Arrowmight and 15 litters in Tecniplast.
