Plant nutrients are important for all life on earth and are also important as fertiliser infood production all over the world. Because of this, plant nutrients are of great valuebut they also bring problems. As an example, the loss of nitrogen and phosphorusfrom agriculture and urban society's sewage systems contributes to some of today?smajor problems in water environment. Another problem associated with plantnutrients is that finite recourses are used in the production of mineral fertilizers.

Genom att fusionera (sammanföra) data från olika sensorer kan ett resultat uppnås som ger mer än de enskilda sensorerna var för sig. Här utreds vilka sensorer och sensorfusionsmetoder som kan vara aktuella att använda för Scanias adaptiva farthållare (ACC). Den adaptiva farthållaren anpassar det egna fordonets hastighet inte bara till en förinställd hastighet utan även till framförvarande fordons hastighet. Scanias ACC-system använder idag en radar för måldetektering.Det finns ett antal algoritmer och arkitekturer som passar för sensorfusionssystem beroende på nivån hos sensordatan och användningsområdet. Minstakvadratmetoder kan användas då data ska matchas mot en fysisk modell, ofta med lågnivådata.

The aim of this study was to understand how evaluations are implemented and used in procured nursing homes for elderly. Our methodological approach consisted of a single-case study research. The case in this study was Växjö municipality. Three procured nursing homes for elderly were chosen in the municipality as examples of implementation and use of evaluation. The method for retrieving empirical data and the analyzing of it was based on triangulation.

Business Analytics används idag i ökad grad i organisationer som grund till beslutsfattande. Ett av villkoren för att kunna använda sig av Business Analytics för att utföra analyser av data från olika källor är att det finns interoperabilitet mellan dem. Syftet med den här studien är att undersöka om det är möjligt att skapa en IT-artefakt som kan hämta data ifrån flertalet XML-dokument med olika struktur för att uppnå semantisk interoperabilitet och på så vis möjliggöra för Business Analytics. Med olika struktur menar vi att benämningarna på taggarna skiljer sig språkmässigt men har samma semantiska betydelse. Lösningen skapas genom forskningsstrategin Design Science vilket innebär att en IT-artefakt utvecklas som kunskapsbidrag, och visar att en implementation av en lösning är möjlig för de semantiska problem vi identifierat.

The digital map product kNN-Sweden contains nationwide data of the country?s forest land. The estimated forest variables are mean age, mean tree height, volume per tree species and total volume. Today Södra Skog?s assessments of timber potentials are mainly based on experience rate and subjective assumptions.

Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition. This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking. The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.

The aim of this bachelor thesis has been to examine and develop our own understanding about how young people in Sweden (16-29 years of age), take part in cultural activities. As librarians it is important to know what kind of activities and interests this particular group has. With Pierre Bourdieu?s theoretical framework towards habitus and capital we are interested to see if there is a connection between one?s cultural use and background, if different access to capital with or within groups has an affect or not. With both statistics and interviews with people within our target, we believe this data has been sufficient enough to conduct a good and valid study.

The global biodiversity loss is mainly due to human activities such as an intensification of forestry. Boreal forest ecosystems in Fennoscandia are characterized by disturbances such as forest fires, storms and floods. However, industrial forestry practices suppress forest fires and change the landscape, leading to a loss of habitats and associated species. Particularly lichen species with slow adaptation abilities and a strong substrate specificity face an extinction debt in boreal forests since their substrates are long-lived but no longer created. In this study the species-substrate relationship of two red-listed forest-fire dependent lichen species Carbon-icola anthracophila and C.

Today, maintenance is a big part of the daily life on board ships. It is also one of the bigger expenses a shipping company has and without any loss of quality tries to run as economically advantageous as possible. In the hunt for economical savings the shore-based industry has subsequently applied the use of condition based maintenance, CBM, were a component is maintained according to its actual state. This leads to a reduction of maintenance costs since no parts are unnecessarily replaced. However, within the maritime sector a periodical maintenance is still the most commonly used maintenance system.The purpose of this paper is to chart the factors that are the reason for the low implementation of CBM on board the Swedish merchant fleet's ships.

The pig industry suffers economical loss due to stillbirths, piglet mortality and low birth weight. This is due to breeding programs that have resulted in larger litters. It has been suggested that these problems are due to the metabolic state of the sow during gestation and the fact that she might not be able to supply her foetuses with enough nutrients for survival and a high and even birth weight. A lot of research has been done to investigate whether body weight and back fat thickness of the sow has any impact on her reproductive traits and if there are any special feed components that improve reproduction. Fibers and unsaturated fatty acids have a positive impact on reproductive traits as long as the sow is fed a sufficient amount of energy and protein during gestation and lactation.

The purpose of this study was to describe the school situation of adolescents who were subject to multisystemic therapy in Sweden, and also if a change could be measured after treatment. Factors that preceded the need for treament were also investigated. The sample consisted of 83 adolescents, boys (65 %) and girls (35 %), with an average age of 14 years. The method used was a secondary data analysis using pre-treatment- and post-treatment data collected from a 7-month follow-up conducted by Lunds Universitet. Results showed that the adolescents were low in school performance and high in truancy at pre-treatment.

Denna uppsats syftar till att studera hur ett analysföretag kombinerar kvalitativa och kvantitativa data i en marknadsundersökning. Uppsatsen bygger på en fallstudie av en marknadsundersökning utförd av analysföretaget United Minds mellan juni och december 2011. Data har samlats in genom tre djupgående semistrukturerade intervjuer med medlemmarna i projektgruppen på United Minds och innefattar även internt material som tilldelats från projektgruppen. I studien framgår det bland annat att projektgruppen kombinerat olika dataformer på ett mer dynamiskt och kreativt sätt än i traditionell akademisk forskning, att olika datainsamlingsmetoder kan prioriteras olika beroende på vad syftet med metoden är i det specifika stadiet samt att forskare kan effektivisera undersökningar genom att utföra så många studie-moment som möjligt sekventiellt. Uppsatsen ger nya perspektiv för både praktiker som akademiker inom det relativt okända området blandade metoder..

Den här studien undersöker hur val av examinationssituationer påverka elevernas prestation i matematik. Syftet är att undersöka hur elever presterar utifrån olika bedömningssituationer. Vi använde oss av en empirisk studie där 12 sextonåriga elever i årskurs 9 genomförde uppgifter i decimaltal från Nationella prov för årskurs 9, år 2009.  I studien använder vi oss av både kvalitativ och kvantitativ data. Data samlades in vid två tillfällen med hjälp av skriftligt test och med hjälp av deltagande observationer under ett muntligt test i par. Hermeneutiken ligger till grund för tolkning av den kvalitativa data.

A new type of device for measuring thev m& ?rate of fuel sprays from a diesel fuel injector has been developed and the various steps in the development are described. The device works by deflecting all of the sprays from the injector at the same time by using a bell shaped deflector. A load cell consisting of a machined steel part with strain gauges mounted on it measures the resulting force. The shape of the curvature in the deflector bell shape has been evaluated by photographing the flow in a 2D?version of the curve shape.
