Identifiering av fosfatfosfors käll- och flödesfördelning i ett litet jordbruksområde
Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.
Datormodellering av en värmelagrande betongväggs inverkan på det termiska klimatet i ett växthus
This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.
Attraktiva gaturum för gångtrafikanter
Efter bilens ökande dominans i gaturummet går trenden idag åt att ge andra trafikslag mer plats, där ibland gångtrafikanter. Olika strategier finns för att skapa gaturum på de gåendes villkor, ett växande koncept i Europa är shared space.Detta arbete sker i syfte att analysera planering för gångtrafikanter i gaturummet. Två fallstudier har genomförts, en på Skvallertorget i Norrköping och en på Götgatsbacken i Stockholm. Arbetet undersöker hur planeringen skett i de två fallen, om åtgärderna höjt attraktiviteten och säkerheten på platserna och även hur gångtrafikanterna där upplever det.För de båda fallstudierna har planerare intervjuats och kortfrågeintervjuer har skett med gångtrafikanter på respektive plats. Dessutom har egna observationer gjorts.Skvallertorget, en torgliknande korsning i Norrköping, är ett av Sveriges mest kända exempel på shared space.Götgatsbacken, en populär gågata i Stockholm har flera funktioner både som shoppingstråk och cykelstråk för cykelpendlare.
Egna varumärken i dagligvaruhandeln - En studie rörande återförsäljarnas hyllplaceringsbeslut
Syftet med denna uppsats är att undersöka i vilken utsträckning och hur egna varumärken favoriseras av de svenska dataljisterna i dagligvaruhandeln, genom ett fördelaktigt hyllplaceringsbeslut. Vi har använt oss av ett kvalitativt tillvägagångssätt med en beskrivande karaktär. Vidare har vi gjort 20 stycken personliga intervjuer med butikschefer på Coop Konsum, ICA Supermarket och Hemköp. Vi har även utfört kompletterande butiksmätningar för att verifiera eller falisifiera informationen. Resultatet som vi kommer fram till ska ses som en utvidgning av befintlig space managementforskning..
Forensic Carving from Unallocated Space
Computer Forensics investigations have become more and more common while investigating IT-related issues. From experience, hard disks, USB thumb, memory sticks contains information that might be useful. Computer Forensics is regulary conducted by Police, Customs, Tax investigators but also within private companies and organisations. However, there are areas within the storage device that are not part of the organisied structure that a file system gives. The reason for that might be that the information has been erased by intention, a virus destroyed the file system and so on.
Mean value modelling of a poppet valve EGR-system
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.
Allsvensk fotbollssponsring
Purpose: The purpose of this thesis is to examine the ERK model's relevance, validity and potential need of development to better reflect how it looks today (2013). Method: The study is conducted through three surveys; the first two were face interviews with companies that sponsor Swedish soccer teams and the third study was conducted with a questionnaire to supporters outside a soccer stadium. Results: A model that would better reflect the reality of today (2013) could contain company pride, chairman?s whim, exposure, relationships and associations..
Modellering och reglering av drivenheter i gaffeltruck
To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.
Delad yta, dubbel yta? : En studie om Dragarbrunnsgatan i Uppsala utifrån konceptet shared space
I linje med tidigare forskning bör adoptivföräldrar bli mer öppna för att adoptera ett barn med funktionsnedsättning eftersom det är färre och färre friska barn som blir aktuella för adoption (Glidden, 2000, s.397; SOU 2003:49, s.144-145). Studiens syfte var att öka kunskapen om hur nöjda adoptivföräldrar är med samhällets stöd före, under och efter genomförd adoption av ett barn med funktionsnedsättning. Studiens frågeställning var om adoptivföräldrar till barn med funktionsnedsättning anser att de har fått tillräckligt med stöd från samhället före, under och efter genomförd adoption. För att besvara frågeställningen användes en kvantitativ metod, vilket bestod av en enkätundersökning som var riktad till 31 adoptivföräldrar. Efter inkomna svar gjordes analys av empirin och en resultatredovisning där vi använde teorierna om anknytning och empowerment.

However, it contains a comparison between two different systems that checks building models.
Att smöra för EMV kan smälta kategorin
Private labels have been increasing a lot during the last 30 years. The reason is great margins and it also works as an aid to build a store's brand. The problem is that private labels take market shares from national brands. Retailers need to have a good mix between these products and adopting category management without being influenced by opportunism, which can lower the profitability of a category. The purpose of this study is to examine and describe how private labels are prioritized in the category edible fat.
