In Sweden, reduced tillage usually means non-inversion tillage, where primary tillage is carried out using chisel ploughs or disc implements. Primary tillage method is mainly determined by the desired soil loosening and the handling of soil residues. The effect of tillage depth was studied in field experiments in Skåne, Väderstad, Uppsala, Örebro och Västerås in different crops; spring oilseed rape, spring wheat, winter wheat and spring barley.The experiments generally had a randomized block design with the treatments mouldboard ploughing, deep chisel ploughing and shallow chisel ploughing, in some cases also shallow discing and no-tillage. In the experiments the following parameters were determined: seedbed properties, saturated hydraulic conductivity, penetration resistance, number of emerged plants and crop yield (all parameters were not determined in all experiments. Root growth and draught requirement were determined in two separate studies. There were no significant differences between tillage depths in non-inversion tillage in seedbed properties, plant emergence or root development.

Denna uppsats presenterar en historisk exposé kring den visuella och tekniska utvecklingen av stridsvagnsanimationer. Detta med fokus på perception och kognition utifrån definitionerna abstraktion, realism och hyperrealism. Uppsatsen ämnar förklara i bild, text och rörlig media hur utvecklingen sett ut och hur långt den har nått. För att åstadkomma detta har en analysmatris tagits fram, ur vilken valda beståndsdelar i spelen Battlezone, Battle Tank och Battlefield 1942 dissekeras. För att ytterligare påvisa kontrasten i utvecklingskurvan, har jag haft Craft Animations och deras verktyg till min hjälp.

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Thesis purposeThe study aims to examine the effects vertical and horizontal line extensions might have on the total parent brand equity in terms of strength and its baseline product regarding of market share, loyalty and penetration under an elapsed period of time. The study aims to investigate a number of actual conducted line extensions effect on the above mentioned aspects of Kellers (1993) definition of brand strength as a part of the total brand equity. MethodologyThe effect of a number of line extensions of the parent brands and the baseline products is being examined in terms of market share, loyalty rate, cannibalization and market penetration. The thesis is focused on the correlations between these different parameters during a certain elapsed time ratio in order to test our theoretically routed hypothesizes in a deductive manner. Occasional correlations are derived from an indexation of data collected from the Gfk database.

this paper is a study on children's social interactions in role-play. The aim is to try to highlight how children with other develop social skills and how to further motivate children tosee, understand and manage their reality in role-play by highlighting the characteristics of afunctioning role-play. I would also highlight the importance of pedagogue´s role in relation tochildren's social skills in role-play. The purpose flows into these issues, what distinguishes afunctioning role-play? Can the children in role-play influence their thinking to developunderstanding of others and the environment and if so, how? What significance does pedagogue´s role in children's role-play? I used out of a qualitative methodology to carry out this investigation.

Intermodulated force microscope (ImAFM) is a type of dynamic AFM. ImAFM opens up possibilities for mapping the topography and making quantitative determinations of material parameters at the same time. With increased information the need to generate more informative images of the sample emerges. In this Bachelor's degree project I have created tools for rendering images of a sample. The topography is plotted as the height and a material parameter is color coded on topography.

The cardiovascular system is one of the three major body systems. When an animal in a critical state arrives at the animal hospital, it is important to know the normal parameters in order to assess the patient?s cardiovascular status. Triage is a process where you considerate the patient?s condition instead of check in time, or other criteria.

The most vital for a business is to understand how to please and satisfy its customers in order to make them loyal to the company. Companies weapon for competition in the retail business is defined through the retail mix. The retailer however often have limited resources whereas they have to prioritize between the factors included in the retail mix. The main purpose for this paper is to investigate what kind of internal connections that may occur between the factors in the retail mix, with focus on the job satisfaction as a catalyst on driving the values of the parameters included in the retail mix, where the factor service is the starting shot for the others included..

In this masters thesis we consider a method for experimental identification of the inertial parameters of an industrial robot, using measured torques and joint angles. A dynamic model of the first three joints of the robot has been identified.To achieve good identification results, it is important to carefully choose the trajectory for the experimental identification. A method to generate trajectories using two suggested design criteria has been used and evaluated using an ABB industrial robot, and one of them yields good identification results..

Syfte Syftet med litteraturöversikten var att beskriva förekomst av whiplashtrauma hos TMD patienter. Metod En systematisk litteratursökning av PubMed, CochraneLibrary och Bandolier databaser genomfördes för artiklar publicerade från 1 januari 1966 till 11 november 2011. Den systematiska sökningen identifierade121 artiklar. Efter borttagning av brev till redaktion och författarinlägg, utfördes en initial screening av abstract på 108 artiklar. Efter den initiala screeningen lästes 32 artiklar i fulltext med tillämpning av inklusions- och exklusionskriterier.

The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

Känslan och trovärdigheten en animerad karaktär i film eller spel förmedlar är viktig för ett bra resultat. Denna känsla och trovärdighet är dock något som är svårt att nå fram till. Med hjälp av teorier från en koreograf och dansteoretiker vid namn Rudolf Laban undersöker detta arbete om det går att lättare hitta fram till en bra karaktär. Åtta gångcykler har skapats utifrån Labans åtta rörelsekaraktäristika,  alla gestaltade med samma figur. Dessa gångcykler har sedan använts för att besvara frågeställningen om det med en neutral figur går att visa på karaktär, endast genom rörelser.

The aim of this master thesis was to create a dynamic model for the processes in a solid fuel boiler of the moving grate type. Another aim with the model was to keep it as simple as possible but still able to catch the dynamics of the processes in the bedplate of the boiler. The creation of the model had its origin from drying and combustion equations used in earlier modeling work of boilers. The represented model has been used to simulate different kinds of disturbances in a boiler and different ways to control the boiler. These tests show that controlling a number of parameters in the bed of the boiler is an effective way to keep the grate stable during disturbances.

Det här arbetet syftade till att undersöka om de skakningar och ryck som uppstår vid en dålig motion capture-inspelning, kan användas till fördel i skräcksammanhang och utveckla den skrämmande egenskapen hos en zombiekaraktär. Som bakgrund har undersökningen gått igenom litteratur kring Zombies, The uncanny valley, Das Unheimliche och deras förhållande till spel.Till det material som skapades till undersökningen genomfördes en motion capture-inspelning och sedan skapades tre stycken videoklipp föreställande en zombie. Datan ur inspelningen redigerades på tre olika sätt och varierade mängden ryckighet i zombiens rörelser. Undersökningen utfördes med intervjuer av både icke-skräckerfarana och skräckerfarna informanter.Resultatet visade att det klipp där skak och ryck tillförts uppfattades som mest läskigast av en majoritet av informanterna. Slutsatsen skulle däremot ha kunnat validerats i högre utsträckning med fler intervjuade informanter..

The fertility of dairy cows is of great importance in order to maintain high production. The decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.
