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.

A comparison of methods to assess site index in young Norway spruce stands

This study investigates whether the site index curve method (SICM) and the growth intercept method (GIM) can be used for site index predictions in younger Norway spruce (Picea abies (L.) Karst.) stands than recommended by current guidelines. For SICM it was thus investigated whether the method could be used for stands younger than ten years, and for GIM it was tested whether a starting point for the intercept measurements could be used below the recommended 2.5 meter. This was tested based on measurements taken from experimental stands in Tönnersjöheden Research Forest. For GIM it was found that the method can only be used when the TH-trees of a stand have five complete intercepts above 2.5 meters. For the method to be applicable beyond this, it will be necessary to adapt the underlying equations, perhaps following the Canadian example where a 1.3 meter intercept start is used. In conclusion it is not currently possible to apply the approach beyond the current recommendations. For SICM, SI predictions are accurate for the study area already form year three.

Förändring av grönområden i Västerås tätort det senaste seklet : Konsekvenser av att grönområden förändras

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.

Manuell arytmitolkning och defibrillering prehospitalt för att minska avbrott i bröstkompressioner

Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew.

Insatsens akustik och dess påverkan på hörapparatens förstärkning

The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

Nationell kultur&Relationsmarknadsföring : Nationella kulturella olikheters betydelse i affärsrelationer mellan svenska och japanska affärsmän

The globalisation of the world is believed by some to homogenise individuals from different national cultures. However, the values and norms of an individual are deeply rooted in their national culture and are therefore difficult to change. Since birth these values and norms are learnt through interaction with others within a specific national culture. The differences in values of a national culture are shown in the cornerstones of the nation. These cornerstones are language, aesthetics, religion and social institutions.

Älgbetesinventering på Orsblecks viltvårdsområde

The purpose with this report is to compare moose browsing in young stands within a small game preservation, and if there are any differences between two areas. The method used in the inventory is a local damage caused by moose browsing survey. It is suitable on areas that have more than 50 hectares but less than 250 hectares of young forest. Inventory of moose browsing is best done on bare ground in the spring and should preferably be done before the flushing begins at the pine. Orsblecks game management area is divided into two different moose management areas, Noppikoski and Siljansringen. During the winter Siljansringen has a denser winter strain of moose, because of the moose seek out lower parts with less snow during the winter. This should also lead to the southernmost part should accommodate larger proportion of damages caused by browsing by moose.

The legacy of the mill : a metal polluted forest soil in Gusum

Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.
