Skogsbränsledrivare i klen förstagallring med contorta

The aim for the study was to examine a harwarder´s (combined harvester-forwarder) productivity when harvesting forest fuel in first thinning stands that contains Lodgepole pine and calculate the economy of the harvesting work and estimate the quality of the thinning . The field study area where located near Arvån, about 15 kilometres south ?east from the city of Lycksele. The field studies were taken place in three different stands. All tree stands had the same tree age, but the tree species combination and the density varied.

Trädgårdsergonomi : om konsten att undvika de vanligaste riskfaktorerna för hälsan i små trädgårdsföretag med krukodling

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.

Hur hanteras vildsvinets (Sus scrofa) populationstillväxt i Sverige idag?

The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.

FE safety analysis of a high speed wood planer cutter. An alternative method to achieve the requirements of EN847 standard

In the last decades, high speed cutting has become an attractive technology in the wood industry. The possibility of reducing global costs in addiction with an increase in productivity, were the main reasons for the enlargement of the use of this technology. As usual, these advantages are accompanied by disadvantages that should be carefully analyzed. If on the one hand cutting forces are reduced with increasing cutting speeds, on the other hand, the centrifugal forces affecting the tool are higher. Exposed to such high loads, there is a considerable risk of tool failure that embeds hazards for both machine and workers.

Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

Mindre åkeriföretags konkurrensstrategier

The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.

Utbildningen av nyanlända elever i gymnasieålder : Nationella utredningar och lokalt arbete i Södertälje och Malmö kommun

 The purpose of this thesis is to study the education of newly arrived 16-20 year old immigrants and how their education in the towns of Södertälje and Malmö matches up with national inquiry into the subject.The research questions in this thesis are as follow: What type of documents shape the work with newly arrived students? What's the preferred development surrounding the education of the newly arrived students nationally? What does the latest study, which is a proposed reform of the Gymnasium system, say about the education of newly arrived students?How does the local work connect with proposals of national investigations? Do the cities take responsibility for evaluating the education of newly arrived students? From arriving to graduating, what does the road to graduation look like for a newly arrived student? What is the curriculum of a newly arrived student?The methods used here are studies of investigations made primarily by Skolverket (The National Agency for Education) and Myndigheten för skolutveckling (The Agency for Development of Education), studies of local documents such as annual reports of quality and promotional material for programs at local Gymnasiums (High Schools), and interviews with local persons in charge of shaping the work with newly arrived immigrants.This thesis has not used theory as a foundation for structuring the analysis, but postmodern theory and the use of three dimensional power inspired the thesis.The conclusions made focuses on the future of the education for these teenagers at large and makes connections between the national investigations and the local work with immigration education.In order for these teenagers to be allowed to join the Swedish national Gymnasium, they need to learn Swedish, and integration seems to be an important part of learning Swedish quickly. .

Geografisk prioritering av CTI-utrustad virkestransportkapacitet

Previous studies of central tire inflation (CTI) in truck transport of roundwood have shown potential benefits to include more even wood flow and reduced road damage. The greatest benefits are found to be during periods of low bearing capacity such as spring thaw. No previous studies have examined geographical variations in the potential benefit of CTI-equipped trucks. The aim of the study was to develop and use a simple method for geographically prioritizing the use of CTI-equipped trucks within a forest company´s sector of activity.The host company for the study was Holmen Skog. The area studied consisted of Holmen Skog?s entire sector of activity extending from the province of Västerbotten to the province of Småland.

Värdeinverkan vid avsaknad av väg : Hur påverkas marknadsvärdet om väg fram till fastigheten saknas?

Syftet med studien är att ta fram ett grundläggande material för vidare undersökning avseende högre kvalitet vid taxeringsförfarandet i samband med justering av taxeringsvärden när väg fram till småhusfastigheter saknas. Detta då det idag inte finns några riktlinjer kring denna justering. Målet med studien är att undersöka vilken värdeinverkan avsaknad av väg till småhusfastigheter kan anses ha på marknadsvärdet, och vad som gör denna värdeinverkan svår- eller lättbedömd.Metoderna som tillämpats i studien avser en kvantitativ- samt kvalitativ undersökning. Den kvantitativa undersökningen har genomförts i form av telefonintervjuer med mäklare och fastighetsvärderare. Detta för att få en generell bild av hur marknaden anses uppfatta förhållandet avsaknad av väg.

En färdig trädgård : enkätundersökning om gruppbebyggda småhusträdgårdar

The main purpose with this master's thesis was to develop a survey with the intention to examine what expectations the JM AB:s customer had on a future garden and also to discuss if the lawn has a symbolic meaning in gardens. The lion's share of the thesis is based on a survey, aimed at people in the company's customer database. The intention was to examine what expectations they had on their future garden and if their expectations were met when they later bought a house from the company. The work also consists of interviews and visits to areas with newly built homes. I interpreted the result from my surveys as the lawn on its own being is a strong symbol for a garden and also signals a social status of the owner. To the company the pre made lawn on a role is a way of saving time and easily achieve what the customer request. The company wants to create a concept of a "preset-garden" that meets the company's vision as well as the expectations of the customer.

Aktiv lastbilsstol för bättre förarergonomi och hälsa

The project concerns a predevelopment work for Scania AB, a leading manufacturer of heavytrucks, and was performed as a master thesis work for the program Design and ProductDevelopment at KTH. The purpose of this work was to examine how the work situation of truckdrivers, especially long-haulage drivers, can be improved with respect to prolonged sedentaryoccupation. Mental fatigue and under-stimulation due to low cognitive load during long drivescan be major risk factors for traffic accidents. Physical strain injuries to both the skeleton andmuscles are common for this working group and minimal opportunity for daily exercise alsoincreases the risk of developing blood clots in the legs, which can have serious consequences forthe driver's health.An extensive background study, both theoretical and exploratory, was performed to identify thedrivers' concerns and comfort needs. Various treatments such as massage and active sitting wereinvestigated and existing products within the area studied.

De bortglömda stenarna : om byars äldre gränsmarkeringar och rågångar i Ekeberga socken

This essay is about the hamlets´ older boundaries, i.e. boundary lines (?rågångar?) and boundary markers in the form of rocks, and an own survey of two hamlet boundaries in southeast Sweden. Many of the boundary rocks were subjected to unintentional damage or destruction that arose during forestry activities, the excavation of ditches, or road construction. Boundaries between hamlets sparsely populated areas were not clearly defined from the beginning, but were established initially in the form of boundary zones, that often consisted of wetlands, watercourses, or mountain heights.
