I Europas hjärta; Det brittiska ordförandeskapet under förhandlingarna om EU:s långtidsbudget 2007-2013

This thesis analyses the 2005 UK presidency of the Council, and more particularly the negotiations on the future financing of the European Union. The purpose of the study is to discuss whether the holding of the presidency implies political influence for the member state. To analyse the power of the country holding the chair the thesis focuses on the presidency functions of brokering and leadership. The theory suggests that the influence of the presidency is derived from informational and procedural power resources, as well as some leadership resources, such as coercion and reward. A case study was used to analyse whether these power resources were used by the British presidency.

Kontaktförbindningar på räls : Undersökning av hur pinnlödning och borrning påverkar materialet i järnvägsräls

Vid dragprovning av lödningar framkom att i många fall är kopparledningen svagare än själva lödningen och brottet sker i kopparledningen eller i kabelskon. Undersökning av mikrostrukturerna visade att det bildas martensit i grundmaterialet i ett område under pinnlödningarna. Medelvärdet på martensitlinsens storlek beräknades till 10,69 mm i diameter och 0,73 mm i djup. På grund av att grundmaterialet påverkas bör pinnlödningar sättas minst 10 mm från varandra. Lödningar gjorda i -5°C visade inga tecken på försämrad kvalitet med avseende på lägre hållfasthet eller ökad martensitbildning.

Effekten av klimatförändringar påkontrollbehovet av åkerogräs

With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.

Problem med lageranknytning hos en bilåterförsäljare

In this paper we have looked closer on a car-retailer in the middle of Sweden. We have chosen to dig deeper in the different problems that can occur, related to the supply. Soon we realized that that the problems weren?t related to stock management. Through studying the whole of the company, we have identified reasons to why details aren?t in the stock.

Optimerad höstveteetablering : en litteratursammanställning om såtid, radavstånd och utsädesmängd

This bachelor thesis is intended to gather the knowledge and experimental data on the winter wheat crop production relevant for Swedish conditions, with focus on sowing time, row spacing and seed rate. This essay is a literature study with a minor component based on interviews with farmers producing winter wheat. The work is divided into a background part where basic knowledge of winter wheat physiology, development and environment interactions are described and one part where results of field trials studies are presented. Optimal date of sowing winter wheat depends on annual weather variations. Because it is difficult to forecast the weather the choice of sowing date should be based on weather statistics, production experience and previous results depending on sowing date.

Givarkonstruktion för beräkning av sådjup

This report shows the process of the development of a sensor module for the seed drills of Väderstad Verken AB. The module is supposed to replace existing solutions, provided that it is better from both a constructional- and an economical aspect. The purpose of the sensor is to continuously give the driver information about the level of height of the front- and drilling tools and the main purpose of the sensor is to allow the seeds to be placed at the desired depth. The sensors which have been taken into consideration have all been of an analogue type and have a protection class of minimum IP67.The methods applied have been taken from the book ?The Mechanical Design Process? by David G.

Slitundersökning för jordbearbetning och sådd :

In this study we try to focus on the costs for wear parts on different type of soil tillage machines and at Väderstad Rapid drilling machine. We have studied some of the leading types of cultivators and disk harrows. Among the cultivators we have investigated Väderstad Cultus, Dalbo Dinkomax, Horsch Tiger and Terrano. At disk harrow we have looked at Amazone Catros and Väderstad Carrier. We have made more detailed study on costs for wear parts, working depth, driving speed and diesel consumption.

Tillväxtreaktion på kvarlämnade träd i Hagners "Naturkultur" försök :

The primary goal of this study was to investigate how the radial growth of retained trees responds after thinning-from-above. The National Board of Forestry which initiated this study, was interested in whether there were differences in the growth-response between the tree species Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) Karst.). Another question of issue was if there were differences in the growth response between trees of different sizes. It is within the framework of the National Board of Forestry?s, Continuous Forests Project that these urgent questions are to be answered.

Värdeskapande i samband med förvärv: - om nyckelfaktorer i en förvärvsprocess

The acquisition process as an object for research and empirical studies have increased in importance during the past decade. The purpose of this thesis is to investigate this process further. This was done by reviewing previous research covering the area of mergers and acquisitions. Seven key factors that should be considered in an acquisition process emerged; acquisition project management, planning, communication between the acquirer and the potential target, goal alignment within management, company-cultures, a trade-off between a certain speed in integrating the companies and consideration of the employees, and finally the follow-up. These factors have been shown to increase the likelihood of value creation in acquisitions.

Återanvändning som kommunikativ resurs : En samtalsanalytisk studie av kommunikation med PECS hos en pojke med diagnosen autism

Communicative recycling, to repeat utterances uttered by oneself or others, is a common phenomenon in all societies and languages. The talk of persons with autism often features recycling. The aim of this study was to identify different forms of recycling in communication involving a boy with autism and to describe its functions. Communication between the boy with autism, who used Picture Exchange Communication System (PECS) to communicate, and his parents and teachers was videotaped. The conversations took place in familiar settings, in the boy?s home and at his pre-school.

At the bottom of the screw conveyer and the inlet feeder there is a bearing that keep the parts together. However the lubrication of the bearing must be made manually.

Kommunikations- besluts- och informationsflöden i byggprocessen

Construction projects are organized in different shapes and disturbances in the information flow in these processes can lead to problems, such as delays and/or a lower quality. Therefore, a well-functioning interaction between actors and a well thought out-communication at an early stage is of crucial importance. The main question is "How does the communication of decision and information flow in the building process and what barriers and opportunities can be observed?". This diploma work has been written with guidance from Bjerking AB and to answer this question, a collection of empirical data conducted via semi-structured interviews.
