Being able to take a decision on an area you've never seen is a difficult task. It is also complicated to introduce an environment in the best way to benefit its purpose. This study focuses on the differences people notice between 2D and 3D models. To make it more concrete, the study has been linked to a case study called Ha?lsans va?g 255.

Bakgrund: Den 20:e april 2010 inträffade en explosion på BP:s oljeplattform Deepwater Horizon i Mexikanska Golfen. Explosionen uppstod på grund av metangas som under högt tryck expanderade på plattformen och sedan antändes. Detta ledde senare till att oljeplattformen sjönk och ett stort okontrollerat oljeläckage uppstod på cirka 1500 meters djup.          Att explosionen i den mexikanska golfen har påverkat BP negativt och varit mycket kostsamt för företaget är uppenbart, börskursen hade som mest sjunkit med cirka 60 procent. Det kan vara intressant att undersöka huruvida denna katastrof, utlöst av en enskild aktör, också har spridit sig över till andra aktörer i Olja & Gas sektorn.Syfte: Syftet med denna C-uppsats är att undersöka huruvida BP:s katastrof i den Mexikanska golfen har påverkat andra aktörer i samma sektor (Olja & Gas sektorn).Metod: Sekundärdata presenteras som en kvantitativ ansats i form av siffror och för att kunna dra slutsatserna använder vi oss av en deduktiv ansats.I denna studie tillämpas en metodikteknik i form av en eventstudie, där beräkningar av den abnorma och förväntade avkastningen baseras på marknadsmodellen. Vidare har två hypoteser testats, där syftet med Hypotes I är att pröva huruvida information om händelsen i den Mexikanska Golfen påverkar andra företag i samma sektor som BP.

This paper is based on a literature review and interviews made with managers in small-scale nurseries for pot plant production. The review helped to identify the worst occupational hazards in pot plant production. The interviews provided a way to investigate how the nurseries act so as to avoid the worst hazards and what they do to even out work intensive periods during the season in order to get a more even distribution of work over the year. According to available statistics problems with back and shoulders are the most common of the physical disorders and the risk for occupational accidents are high for greenhouse workers. Most of the occupational injuries are connected to musculoskeletal problems. The handling of material is often manual and involves frequent lifting and carrying of heavy loads, the strenuous work postures and static muscular tensions these repetitive tasks are associated with causes straining and overloading.

Huvudsyftet är att undersöka om det existerar väsentliga variabler som kan hjälpa oss att finna framtida vinnarfonder genom att studera historisk information. Studien mäts i förhållande till det existerande utbudet på svenska fondmarknaden. Konkret vill vi kunna få en högre signifikant avkastning under en given period än den genomsnittliga avkastningen för samtliga fonder på den svenska marknaden. Med denna undersökning vill vi bidra till en diskussion om det råder marknadseffektivitet. Variabler som vi studerar för denna undersökning är historisk avkastning, standardavvikelse, Sharpekvot, Stutzer index, fondstorlek, kapitalflöde, relativ volym, trading activity, fondavgifter och slutligen ålder.

The examination of the adequate nature conservation methods in a natural reserve, to conserve a specific species and / or increase biological diversity is the subject of this study. This work is based on four species, that can be found during the Spring season, liverleaf, wood anemone, brimstone and woodpecker. The incidence and availability is studied and closely observed for these species in twenty forests, i.e. ten forests which are nature reserves and ten forests with the similar characteristics as the nature reserves habitat, but are not nature reserves in Gnesta mucipality, Södermanland. Measurements of the tree crown and the diameter of the tree trunks where noted to study how these factors could affect the outcome of the abundance and incidence of the four species.

This thesis is made on behalf of SCA's Forestry Division and is a comparison of two bucking simulation tools: Aptan (manufactured by Skogforsk) and Best/upr (from Berget Systemdesign). The data is based on 32 stands from SCA's forests in Norrbotten and Västerbotten. The objective is to compare the simulations created by the tools with the harvested volumes from those stands. Three variables are needed for the bucking simulation; these are the diameter distribution (at breast height), the relationship function between diameter and height, and the taper coefficients. The volumes of five different assortments from the stands are compared.

The general view of learning has dramatically changed during the last two decades. Today we talk about learning for life and educate to meet the demands of the information society. This new view forces us to constantly relearn and develop new knowledge ? something which has resulted in large restructuring within the upper secondary school. New forms of teaching, where the pupils are given the opportunity to a more active search for knowledge, is developing.

Att investera rätt är en fråga som bekymrat de flesta någon gång i livet. När, var och hur ska det investeraras för att skapa god avkastningen på det satsade kapitalet? Sedan 80-talet har svenskens placeringar och aktivitet på aktiemarknaden vuxit explosionsartat. 1980 hade svenskarna 27,3 miljarder kronor sparande i aktier vilket har ökat till 686 miljarder 2008, ett gott tecken på den ökade aktiviteten på aktiemarknaden.Utöver den privata finansiella rådgivning bankerna erbjuder kan den privata investeraren ta del av aktieanalyser och rekommendationer. Många av dessa når allmänheten genom bland annat tidningar och internet som köp- och säljrekommendationer av aktier.

Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.

Never before have so many moved so frequently as now. Mobility lies at the centre for the concern ofstates, business and technological development. Some even claim that we are witnessing a mobility turn inthe social sciences. However, as the capacity to move has increased so too has the control and surveillanceof mobility become more extensive. Since September 11, 2001 security has been the defining paradigm fora variety for actors.

The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

The intensity of cleaning declined dramatically in the early 1990?s in the Swedish forests. Recession, an economic depressed forestry and the new law of silviculture from 1993, where the duty of cleaning was removed have been considered as sources to the decline. This has led to a situation where huge areas of forests are untouched, which can lead to negative effects for those stands in the future. The purpose of this thesis was to find out how the individual landowner acts and feel when it concerns cleaning activities. Has the landowner noticed Södra?s campaigns about cleaning and what sort of measure should Södra implement to increase the members? cleaning activity? The thesis is based on a opinion poll made through a random draw among all Södra?s members.

This thesis work has been performed at the Division of Assembly Technology at Linköping University for a period of ten weeks. The work is part of the project ProFlexA, which is a research project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB.The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that the cast can be sold. Automation has long been sought for the cleaning of castings due to, among other things, poor working conditions for staff, but this has proved difficult to implement with today's technology. Automation has for some time been available for more capital strong companies with large annual volumes, but for smaller companies with small-and medium-sized volumes, automation has not been an option.The goal of ProFlexA is to develop an automated cleaning cell aimed at small-and medium-sized volumes.The goal of the thesis is to do a pre study at ProFlexA?s partners on cleaning of castings, and develop concepts for automated cleaning of castings.By recording the process and cycle times, the cleaning of castings has been documented as it works today, and on this basis, information and statistics has been compiled.

Vid ett G20 möte i Pittsburgh den 26 september 2009 togs ett beslut om att marknaden för OTC-derivatkontrakt behövde någon form av reglering. Tidigare hade brist på insyn medfört att det var svårt att uppskatta de risker som dessa kontrakt innebar. Detta kom att leda till att regelverket EMIR implementerades i Europeiska unionen. De huvudsakliga åtaganden som EMIR kom att innebära var ett rapporteringskrav gällande dessa affärer, ett clearingkrav vid omfattande användning av dessa typer av kontrakt samt implementering av förfaranden för att minska risk. I regelverket sägs dock att clearingkravet undantas om det går att bevisa att de ingångna OTC-derivatkontrakten motverkar risk i ett företags verksamhet och ej är ingångna i spekulationssyfte.Då EMIR påverkar alla de aktörer som använder sig av OTC-derivatkontrakt påverkar även detta regelverk Scania.
