A field experiment was carried out in 2006 to investigate the effects of deep rotary cultivation on sugarbeet growth. The background to the experiment was a 2005 study showing potentially higher yield, higher cleanness and higher sugar content when primary tillage was carried out to 35 cm depth with a rotary cultivator. On four field sites in Skåne (L:a Isie, Ädelholm, Stävie and Vragerup), five different treatments were compared: mouldboard ploughing in the autumn to 20 cm; mouldboard ploughing in the autumn to 20 cm + rotary cultivation in the spring to 35 cm; rotary cultivation in the autumn to 35 cm; rotary cultivation in the spring to 35 cm; and mouldboard ploughing in the spring to 20 cm. The rotary cultivator used in the treatments is manufactured by a Dutch company, Imants. The implement cultivates the soil with spade tines fitted on arms that are mounted on a horizontal rotating PTO-driven axle. Beet plants were inspected and yield determined in the experiment, and three soil parameters were examined: penetration resistance, water infiltration and infiltration of blue dye. Root shape was also examined. The site at Stävie was not harvested due to poor beet establishment. At the other sites, the highest yield was found when the soil was rotary-cultivated in the autumn.

The third most common conifer in Sweden is Pinus contorta (lodgepole pine). It originates from the western part of North America and was brought here in the end of the 1920s. The lodgepole pine is today allowed for commercial plantations in central and northern Sweden, excluding high altitude locations. Since 1979 only plantations with scientific purpose are allowed in south-central and south Sweden. This document is focused on how lodgepole pine manage perform compared with Pinus sylvestris (Scots pine) in the southernmost part of Sweden, Götaland. The idea came from the fact that the Swedish government is evaluating a notification from the National Forest Agency that suggests lodgepole pine to be allowed for commercial plantation even in southern Sweden.

Background. Immunohistochemistry is a useful method in the differential diagnosis between pleural mesotheliomas and metastatic adenocarcinomas in the pleura. Cytokeratin 20 and 7 have been used successfully as markers in studies determining primary location of adenocarcinomas from metastases. The current study is a complementary research of archived paraffininbedded material of cases with cancer origin. This study contributes a bigger statistical material that may facilitate the search for unknown primary site of adenocarcinoma by identification of metastatic cells in the pleura.Methods.

Bacillus anthracis is the causative agent of anthrax, a serious and globally distributed zoonosis affecting a wide range of wild and domestic animals, invariably also humans. However, although known to humans since biblical times, much remains to be elucidated concerning the ecology and transmission of this bacterium. Of particular interest is the Bacillus anthracis spore, the uptake of which is the predominant way to contract anthrax and which is legendary for its resilience in the environment and thus crucial for persistence and spread of the disease. Hence, the aim of this study is to review the natural transmission of Bacillus anthracis and investigate potential means by which soil persisting Bacillus anthracis spores reach concentrations sufficient to infect susceptible hosts. When reviewing the literature, three different theories can be distinguished. Firstly, ?the incubator area? hypothesis suggests that favourable soil factors, possibly in association with amoebas, may constitute an environment supporting repeated spore-bacterium-spore cycling, thus increasing the local amount of spores.

This thesis is based on design theory about how to build an application for the mobile platform, a scientific analysis and an application for grocery shopping and meal planning. The thesis also contains a valuation of the research and of the application. The valuation of the application was done by a usability test and an analysis of the results of the test.The application of the thesis has an easy navigation system, which is time saving and simple to use. Finding recipes with the associated ingredients is a quick fix. The search function can be used for searching freely after recipes as well as for separate ingredients. That makes it possible for the user to create own recipes from available ingredients.

AbstractTitle: The New Type of Music Industry at AllEars.se (Den nya musikbranschen på AllEars.se)Number of pages: 49 (53 including enclosures)Author: Viktor BackemarTutor: Else NygrenCourse: Media och Communication Studies CPeriod: Fall 2007University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose: The purpose of this paper is to compare AllEars´ own view of the website AllEars.se to an observed view of the same site. The comparison is based on theories regarding the Internet in today?s society, convergence, communities and collective intelligence, interactivity and participation, and business in today?s society.Method: Since the paper has a purpose to compare two views of the same website there are two main methods in use. AllEars´ own view has been created via an interview with the company?s CEO, a press release that was released in connection with the launch of the website and texts found on the website.

Problem: The corrugated board industry is highly affected by customer uncertainty, various demands and short delivery times. In combination with a complex multi-step production process managers have to be able to identify bottle-necks and gain knowledge and understanding of how different changes in process will affect the production output. <br/><br/>Purpose: The purpose of this master thesis is twofold, (1) to examine applicability of complexity theory through agent-based modelling on a production process (2) to identify improvement areas in order to increase the production output at SKS production site in Eslöv, by modelling and simulating the production process through an agent-based model. <br/><br/>Method: The chosen method of this study is a combination of a case study and a complex system approach. The empirical data was collected through interviews, observation and document studies which were analysed through an agent-based simulation model.

Problem discussion: That empowerment and autonomy can lead to desirable effects on employees is clear. Previous research has found correlations between empowerment and e.g. motivation, job satisfaction, productivity, loyalty and commitment. However, a control problem arises when employees have more freedom in decision-making which could potentially lead to undesirable outcomes. It thus becomes a type of dilemma for management and managers where you have to try to balance a restrictive use of the control system (to maintain control) and an enabling use (to promote empowerment).Purpose: The purpose of this study is therefore to identify how a company can use its control system in order to achieve empowerment while maintaining acceptable levels of control.

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

This study is about Wikipedia which defines itself as a free online encyclopaedia. Our chief interest lies in the debate and the controversy which has arisen around Wikipedia. After reading critical articles concerning Wikipedia we found that the debate for most parts had one identifiable theme namely the question whether Wikipedia is an encyclo-paedia or not.Encyclopaedia as a term and a phenomenon has a long tradition. Wikipedia, despite calling itself an encyclopaedia, functions differently in comparison to more traditional encyclopaedias. These traditional views involve encyclopaedic structure, its organiza-tion and its functions.

The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

During the last few years the harwarder has developed from a prototype into a market product. Holmen Skog owns two harwarders and uses two more owned by entrepreneurs. In previous studies it has been shown that the harwarder was a slow and expensive forwarder. In this study the unloading at road-site was studied. The goal was to describe the differences in time consumption between unloading two-sided or single-sided (only from side of the road) and also the difference between unloading with three and four assortments in the carrier.

Background and problems: All that is stated in social media might not always sometimes be right, which has consequences for the individual's view of the described phenomena. The individual interprets and takes in mass media messages, which can lead to that the wrong information makes believed to be is correct one. The news media?s photo illustrations might pictures result in bad images of the suburbs. Hovsjö, residential area in the city of Södertälje, occurs in the media depicted as is a bad place to live due to the high rate of crime there.Purpose and Issues: My main research question is: How do young people view their residential area Hovsjö in comparison with the image they believe consider is given in that the news media gives the area? Further questions of the study are: How do the young people of the district describe their residential area? How do the youth's react to the news media images of Hovsjö? Has the neighborhood helped to form their identity?Method: In my data collection I have chosen a qualitative approach with observation and semistructured interviews.

Denna uppsats undersöker ensamkommande barns situation med särskilt fokus på psykisk hälsa. Antalet ensamkommande barn har sedan 2005 ökat markant. År 2008 tog Sverige emot 1510 barn som kom utan föräldrar. Trots denna höga siffra är gruppen relativt obelyst i Sverige idag. De har ofta varit med om högst traumatiska upplevelser och anländer utan anhöriga vilket gör dem till en utsatt grupp.

Today's planning strategy, densification of cities, makes it difficult for municipal authorities to find spaces to build preschools and daycare centers on. The Planning and Building Act , Chapter 8, § 9 states that " if the site should be developed with buildings that contain one or more dwellings or premises for after-school , preschool, school or other activities, it should be on the property or near it, enough free space which is suitable for play and being outdoors. " Each municipality has to define the expression enough free space and a number of municipalities have established guidelines for preschool and daycare centers concerning dimensions. The guidelines measure the number of square meters of free space per child with the aim of contributing to a qualitative environment. But the size is just one quality and the issue is how other non-quantifiable qualities are taken into account in the planning process. The paper compares three municipalities, Gothenburg, Malmö and Lund.
