Tillämpning av en markprofilmodell för hydrologiska beräkningar i avrinningsområdesskala

There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

Ternära koder för variabelt felskydd

Ternary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. Regardless whether the fluctuations of the channel are intentional or not the idea is to let the coderate decrease so that the error correcting capability can increase for the part of the information to be more protected. By using the support, the nonzero positions of the ternary code, a new binary code can be extracted with properties different from the ternary code in the sense of cardinality and minimum Hamming distance. When the channel conditions are good the receiver decodes the message using ternary decisions and receives all information included in the codeword.

Friskvård inom företag : Vilka effekter ger det på arbetsmotivation och stress?

SAMMANFATTNINGBakgrundFriskvård är något som blir allt mer etablerat inom svenska företag idag, mycket på grund av att sjukskrivningskostnaderna i företagen ökar. Människans kompetens ses alltmer idag som ett företags viktigaste resurs. Därför att Sverige idag blivit ett informationssamhälle där personalen blir allt mer stillasittande så har det blivit mer viktigt för företagen att personalen har en god hälsa och mår bra. Många får nu ingen motion via sitt arbete och måste därför aktivera sig på något externt sätt, därför har friskvården börjat växa sig allt starkare.Frågeställning?Hur värderar anställda friskvård och vad har det för effekter på stress och motivation?1.4 SyfteSyftet med denna uppsats är att undersöka hur arbetsmotivation och stress hos den anställde påverkas av friskvård inom företag och vad det i sin tur får för effekter, dels för dom anställda och även för företagen.

Konsten att mäta tjänstekvalitet : En utvärdering av tre instrument för att mäta tjänstekvalitet i kollektivtrafiken

The purpose of this study is to analyze and evaluate the suitability of the three instruments SERVQUAL, SERVPERF and Zone of tolerance to measure service quality, from the respondents' perspective. This study has been carried out by a quantitative method in which respondents answered three questionnaires, which was based on the three instruments. The SERVQUAL instrument is a revised version based on criticism by Carman (1990). It is based on the five dimensions; reliability, responsiveness, assurance, empathy and tangibility, with 22 items in which each dimension is associated with a number of items. SERVPERF is the instrument most similar to SERVQUAL and is also composed of the same five dimensions.

The effect of new raw materials on pellet prices

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.

Enterobacteriaceae och amoxicillin-klavulansyra : Effekt av bestämt förhållande respektive bestämd koncentration av klavulansyra på MIC-värden och zon/MIC-korrelation

Förekomsten av bakterier med olika typer av resistensmekanismer ökar globalt. De varianter som på engelska benämns ?Extended spectrum ?-lactamases? (ESBL) är en heterogen grupp ?- laktamaser som genom hydrolys inaktiverar ?-laktamantibiotika och därigenom ger resistens mot bland annat ? -laktamantibiotika som penicilliner och cefalosporiner. Resistensbestämning på kliniska laboratorier utförs huvudsakligen med lappdiffusion eller Minimum Inhibiting Concentration (MIC)-bestämning med gradienttester. Infektioner orsakade av ESBL-producerande organismer kan behandlas med ?-laktamantibiotika kombinerat med en ?-laktamasinhibitor.

Effekt av sönderdelningsgrad och planteringsdjup på uppkomsten från rhizom av Tussilago farfara :

Tussilago farfara, coltsfoot, is a troublesome perennial weed with deep lying rhizome, which can vegetatively generate new plants. The mechanical control of coltsfoot that is used today, "starvation", which consists of several cultivations of the soil, which fragmentises the rhizome. This results in production of new shoots, which leads to depletion of nutrient resources; as long the new plant is not allowed to establish. However, very little research has been done to investigate how the starving technique affects the regenerative ability of coltsfoot. The purpose of this experiment with coltsfoot was to investigate how fragmentation and burial depths affect the time of emergence, number of emerged shoots per rhizome fragment, number of shoots per node, and if the germination ability within nodes changes during the experiment.

Analys av sambanden mellan informationsflöden och en effektiv produktion : En fallstudie utförd på Koenigsegg Automotive AB

En viktig del i ett företags strävan i att bli mer lönsamt, samt att hålla ned kostnader till ett minimum, är en effektiv produktion. Detta arbete handlar mycket om att identifiera och eliminera slöseri i olika former. Väntan i produktionen är en form av slöseri och kan till exempel uppkomma när personalen inte kan arbeta på grund av materialbrist eller att de letar verktyg eller delar. En annan form av slöseri är att producera eller korrigera defekta enheter.För att minimera dessa former av slöseri krävs förutsättningar för en god informationsstruktur med en väl fungerande kommunikation och dokumentation. Dessa förutsättningar kan erhållas genom standardiserade arbetssätt.

Utveckling av inkontinensprodukt

Together with Attends in Aneby a thesis of 15 ECTS (credits) have been undertaken. The assignment was to develop a new incontinence product for single use. Users of the product value comfort, flexibility, softness, comfort and a discreet product. Users are for individuals with incontinence problems that usually receive the products via prescription. The product must also have an attractive price and good quality from the purchase / originator's perspective.Currently there are two models that Attends supplies, which the project intends to develop, (Slips / Briefs and Pull On's).

Ersättning vid tvångsförvärv av mark ? En typfallsstudie av ersättningen i två olika ersättningssystem

Each year approximately 2,000 new detailed development plans are accepted in Sweden. When an area is covered by a new detailed development plan, it is often necessary that land has to be acquired to adjust the property units to the new plan. The owner conditions of the property units can usually be adjusted through negotiations between the seller and the buyer. But in some situations, when no agreements can be reached, it is possible to use coercive measures to purchase the land. Compulsory purchases are only permitted when certain legal criteria?s are met.

Minska eller inte minska sitt aktiekapital : Hur uppfattar de privata aktiebolagen möjligheten till att sänka aktiekapitalet till 50 000 SEK?

Sänkningen av aktiekapitalkravet från 100 000 till 50 000 SEK den 1 april 2010, förverkligades för att förbättra de institutionella villkoren för de privata aktiebolagen och för att fungera som ett incitament till att öka småföretagande. Syftet med denna uppsats är att undersöka om de privata aktiebolagen har valt att lösgöra eller behålla sitt aktiekapital efter denna nya regel och varför. Dessutom ämnar studien att undersöka om det finns skillnader mellan de som väljer att minska eller att behålla sitt aktiekapital avseende bransch, ålder och omsättning. Studien baseras på en enkätundersökning som innefattar 212 respondenter. De resultat som denna undersökning kommer fram till är: Att majoriteten av de privata aktiebolagen har valt att behålla sitt aktiekapital.Att anledningen bakom att behålla aktiekapitalet är att bevara företagets kreditvärdighet, att använda aktiekapitalet i verksamheten och för att proceduren med att sänka aktiekapitalet anses vara krångligt och tidskrävande.

Tidig postoperativ övervakning av smådjur : förekomst av standardiserade rutiner

Background. Anesthetic-related death in small animal anesthesia is about ten times more common than in human anesthesia. Recent research identifies the early postoperative period as particularly risky and highlights the need for regular and careful monitoring of the veterinary patient during this period. Objective. The aims of this study were to investigate whether there are standard procedures in terms of regulated routine patient observations and record-keeping during the early postoperative period at Swedish veterinary clinics, and if there are any guidelines for monitoring the veterinary patient during recovery. Methods. A small survey including ten Swedish veterinary clinics was carried out as well as a literature review. Results.

Enstudie om lågtempererat värmesystem i vägg : -Fokus på inomhusklimatet och energianvändning

Today the human being see energy as a matter of course but the resources that is used for extract energy is today not enough for the world demand. Of all the energy that is used in Sweden today approximately 40 % goes to the building stock. This number will most likely increase if not necessary actions will be made on the already existing building stock since new houses constantly are built which will be added up on the already existing energy supply. This takes cause of action on the already existing building stocks, to fulfill the demands of the future use of energy that has been set by the authority. At the same time the thermal conditions cannot be influenced by the necessary changes that must be made.

Optimerad styrning av kondensatorbatterier - Ny möjlighet att minska förluster med elektronisk brytteknik

Transmission of reactive power is well known to cause active power losses. Thus, newcomponents who can help minimizing these expensive reactive power flows are ofgreat interest to the power distribution companies. ABB Corporate Research hasdeveloped the first electronic power breaker. One possible application for thisbreaker is transient-free switching of capacitor banks. This could prove a usefuldistribution voltage complement to the switch-sync technique, mainly applied to transmissionvoltage level.

Utveckling och dimensionering av en lastupptagande provningsram

ÅF Test Center in Borlänge had a need to expand their capacity for compressive and tensile strength tests. They wanted to do this by using a hydraulic cylinder, which they already possessed, to apply the force with. This required a load receiving structure. The aim of this work was to design and dimensioning a test bench for a cylinder marked NIKE 300 tons. The work would result in a completed design proposal on a test bench which could manage to run the compressive and tensile strength tests of up to 3000 kN.
