Sänkgnistning är en icketraditionell bearbetningsmetod som i Sverige används av både små och stora verkstadsföretag. Metoden används i syfte att framställa geometriskt komplexa detaljer, främst ur härdat stål. Dessa detaljer används vanligtvis som produktionsmedel. Detta innebär att kunderna använder en eller fler detaljer, som producerats med sänkgnistning som verktyg, för att producera egna produkter. Vanligt förekommande är att kunder använder sänkgnistdetaljen som verktyg för formsprutning vilket ofta genererar många produkter per sänkgnistdetalj.

Debatten om ekologisk kontra konventionell odling har blossat upp allt mer, förespråkare från båda synsätt har sagt sitt genom slagfärdiga debattartiklar och diskussionen har sedan fortsatt vid middagsborden runt om i landet. Denna kandidatuppsats i ämnet landsbygdsutveckling syftar till att undersöka vilka drivkrafter som kan ligga bakom olika aktörers engagemang i jordbruksfrågor och hur de ser på vad som är en hållbar livsmedelsproduktion. Uppsatsen syftar även till att utforska hur informanterna framställer sig själva och andra aktörer i debatten som förts kring ekologisk kontra konventionell odling. Vem bär enligt informanterna ansvaret för jordbrukets utveckling? Behövs en radikal omställning i hela livsmedelsproduktionen för att nå mer hållbarhet eller räcker det med att enbart göra små justeringar? Det empiriska materialet består till största del av fyra informanters syn på dessa och liknande frågor. Detta material har sedan analyserats med inspiration från Erving Goffmans teori om intryckskontroll och Ulrich Becks teori om risksamhället..

Background: The valuation of growing crops is problematic partly due to weather conditions. 2011 showed that of all cultivated crops 42% were autumn sown which makes up a significant proportion of the total arable land in Sweden. This presented an opportunity to investigate more closely the methods and options used in the inventory valuation of biological assets. Problem: What options are there in the valuation of own-produced inventory specifically in the form of growing crops? Objective: This study's aim is to create an increased understanding of an agricultural company's options for inventory valuation of biological assets. In the survey of the options this study has found two main categories: rule-and principle-based accounting. Methods: A qualitative study with an abductive approach.

The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.

This study in the subject of forest planning is made for Sveaskog and its aim is to develop tools that prognosticate outcome in terms of volumes per sort from not yet cut forest stands. The degree of detail is just to get reliable results for at least one months volumes, for Sveaskogs own forestland in the market region of Norrbotten that is about 100 000 m3fub. The course of action to accomplish this is regression analysis and the data consists of cut tracts on own forestland in Norrbotten during the years 2006, 2007 and 2008. That is a little more than 4 million m3fub. Two tools were made.

När man väljer att analysera företag, finns det flera olika värderingsmodeller att använda.En av dessa är Piotroskis F-score. Denna modell har mestadels tidigare använts för att analysera företag på den amerikanska marknaden. Nu vill författarna undersöka hur tillämpbar modellen är på den svenska aktiemarknaden och dessutom kombinera denna modell med en Magic Sixes värdering för att öka dess precision.Syftet med denna studie är att undersöka om F-score i samarbete med Magic Sixes kan generera överavkastning och överträffa den svenska aktiemarknaden.Författarna har genomfört en kvantitativ studie med en deduktiv ansats. Data har samlats in med hjälp av databasen Orbis och Dagens Industri. Författarna har upprättat identiska listor för att beräkna företagens F-score och Magic Sixes.

Pathogenic microorganisms pose a big threat towards food production. Meanwhile, negative impacts on humans and environment are seen by the use of pesticides. Biological control agents are an alternative to the use of chemical pesticides, and plant-growth promoting rhizobacteria, such as Bacillus amyloliquefaciens has been shown to have good properties as biocontrol agents. Before these bacteria can be used commercially their impact on other soil organisms has to be evaluated. This thesis looks into what biocontrol bacteria are and how they might affect earthworms.

Det har gjorts mycket forskning kring Positioneringssystem för inomhusbruk då många applikationer och tjänster ärberoende eller kan förbättras av det. Trots detta finns idag ingen standard för hur positionering inomhus ska fungera.För de flesta utomhusmiljöer kan en modern mobiltelefons position erhållas med ett par meters precision via GPS. I eninomhusmiljö sjunker signalen drastiskt och en precis position är svår att uppskatta. En väl etablerad teknik är Wi-Fioch kan med fördel användas då de flesta inomhusmiljöer idag redan har Wi-Fi accesspunkter installerade. Då enmottagare erhåller en signal från en accesspunkt kan distansen dem emellan uppskattas för att sedan uppskattapositionen med den matematiska tillämpningen trilateration.

The female dog has a unique reproductive endocrinology, with high levels of progesterone throughout the 70-day long luteal phase. In this project, markers of glucose metabolism were studied and compared from the aspects of breed group and time in oestral cycle. The parameters studied were: glucose, insulin, progesterone, fructosamine and the newly introduced analysis of HbA1c. Hba1c was also further evaluated and discussed as a diagnostic tool in canine medicine.No differences in terms of glucose markers were found between a group of purebreed dogs of various breeds compared to a group of dogs with high risk of dioestrus diabetes, namely the Norwegian and Swedish elkhounds.No differences were found between the two sample occasions, anoestrus and dioestrus, concluding that there is no need for relating test results to the time of the oestrous cycle in middle-aged intact female dogs.There were statistically significant higher values of all glucose markers in diabetic dogs than in non-diabetic dogs. When it came to HbA1c, however, there was a larger overlap between the two groups, compared to fructosamine.

Lao People?s Democratic Republic (PDR) is a country where the majority of the population works within the sector agriculture in one way or another. The number of goats are increasing and the animals can be an important income source for families. However, during the dry season, lack of feed is a great problem for the farmers. Fodder trees have shown great potential as dry season feeding, due to that the trees often hold green and fresh leaves a long time into the season, compared to grass that dry out quickly.

Background: Recently, the Swedish food culture has expanded by leaps and bounds. Interest in food and cooking has taken more space in the Swedish welfare state. Products and icons, such as organic free range chicken or Per Moberg have had greater impact on the way we consume food. Consumers have become increasingly aware of what they should and should not be eating. With an increased interest in food, supply and distribution channels have become increasingly important for the major grocery retailers (Board of Agriculture 2011).

The decomposition of organic carbon in drained peat soils is a major source of carbon di-oxide in Sweden. A big part of these drained peat soils are used in agriculture and it is a big challenge to slow down their decomposition. It has earlier been thought that less tilling and higher water table levels would decrease the activity of soil microbes and thereby the decomposition, but recent experiments has showed that this has little or no effect. In this bachelor thesis a field experiment was made on drained peat soil with ley, outside Björklinge, Uppsala municipality, Sweden. The experiment was carried out in May 2011. The objective was to develop a method to examine how the net exchange of carbon diox-ide from plant covered peat soil is affected by temperature and photosynthetically active radiation (PAR).

Underdrainage is a costly investment but often a necessity to maintain rationalized plant cultivation, one can also see underdrainage as insurance to successful plant cultivation. Late ripening crops, low yield and difficult tillage cultivation are examples on an insufficient drainage. (Kvarnemo 1983) A drained field rise in land price and the scheme of the tiled drains is seen as a value item. The interest for underdrainage among the farmers follows with shifting economic situations within agriculture and has for long time been low. A big part of the Swedish tiled drainage systems is since 1930 and ahead. Many of these tiled drainage systems need to be replaced or complemented. The life length of one tiled drainage system varies with maintenance but can still remain in good function after 75 years with correct management.

A Quick Test (AQT) Färg och Form är ett test av snabb automatiserad benämning avsett att detektera kognitiva störningar. Det består av tre delar som var och en utgörs av 40 visuella stimuli som skall benämnas så snabbt som möjligt. Tidigare studier har indikerat att AQT skiljer personer med Alzheimers sjukdom från friska kontroller med högre precision än det ofta använda Mini-Mental-Testet (MMT). I denna studie undersöktes för första gången om AQT-resultat kunde predicera diagnosen hos en konsekutiv serie patienter vid en minnesklinik samt relationen mellan AQT-resultat och biomarkörer (likvorproteiner) för neurodegenerativ sjukdom. 492 svarsblanketter från AQT Färg och Form analyserades och diagnostisk prediktion samt korrelation med nivån av likvorproteiner fastställdes för de 374 första patienterna i serien.
