Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.
Att veta Gudarnas hemlighet : En sårbarhetsanalys av omständigheterna kring stormen Gudrun med pressure and release modellen
The concept of vulnerability is the capacity or the sensitivity to become damaged. Vulnerability are characterized by one or more of the following terms; a system´s sensitivity to exposure to shock, stress or interference, the state of the system in relations to a threshold of damages, and the system´s ability to adapt to the changing circumstances. Vulnerability in this study is referring to the sensitivity of the circumstances that lead to sustainable livelihood that can´t be maintain and that there is an inability to cope with and manage stress. The choice of making a study in this area is based on that action needs to be taken to moderate the vulnerable aspects of society, in this respect in relations to storms. Analyzes of the social vulnerability to climate change or natural events is needed for effective actions.
Vad orsakar skador på kvarstående träd vid mekaniserad gallring - en intervjustudie
This thesis includes a review of scientific studies of tree injuries following mechanized thinning. Interviews have been made with drivers of single grip harvesters and forwarders in forest thinning and a number of essential factors have been identified as the most important to take into account in order to minimize and/orprevent injuries to stems and roots of remaining trees..
Advantages and disadvantages of different observation methods on a troop of wild olive baboons at a river in Southern Kenya
Every observation method has its advantages and disadvantages and a well-adopted method gives more reliable results. Factors affecting the choice of the most appropriate methods for recording foraging behaviours include species, group size, environment, seasons and age. The focus for this study was to determine which method is most appropriate for studying the foraging behaviour of a troop of 89 olive baboons (Papio anubis) living in a riverine forest by the Southern Ewaso Ng'iro River by Lale'enok Resource Centre in Kenya. To determine this, a literature study was carried out to compare methods from monkeys and apes. I found instantaneous sampling was the most common method with intervals of 5 minutes in most cited studies.
Hav och Strand : stenteknologi och marin anpassning på Gotland under Senboreal/Tidigatlantisk tid
The essay circulates around the technological analysis of flint material from four localities around the Baltic Sea basin. The analysis was created to investigate the question of where the first Gotlandic settlers originated from and to give clues about the colonization process. The investigated material was collected during the fall of 2011 and a correspondence analysis is used to analyze the collected material. The purpose of using a correspondence analysis is to test the method as a tool for investigating Mesolithic flint technologies. The essay also discusses marine hunter-gatherers, their economy and how their archeological remains differ from terrestrial hunter-gatherers..
Downsizing : Hur överlevare av uppsägningar påverkas av upplevelsen
In today?s business environment, cost-cutting practices such as downsizing and layoffs remains a widespread phenomenon. Although, the understanding of the effects that these practices has on the remaining individuals, defined as the survivors, is poor. The focus in this paper is therefore to examine how survivors of layoffs can be affected on an individual level, and by what causes.The study was conducted using open-ended, qualitative interviews with three individuals with different experiences of layoffs. The empirical data was analyzed by extracting quotations from the interviews.The study found that layoffs affected the morale and attitude towards management of the individual, and that perceived justice and uncertainty are two causes of negative effects from layoffs..
Ljud i landskapet : Akustikarkeologi och öländska klangstenar
The aim of this work is to give an example of how archaeoacoustics can broaden our understanding of archaeological remains and to further contribute to the almost non-existing research of ringing stones. With a theoretical discussion about sound from three different perspectives and by means of using different kinds of analysis, this essay will show that there are unknown relations between the three known ölandic ringing stones and the cultural landscape of Öland. Possible patterns in the placement of the stones and the possibility of the sound in this soundscape will be investigated. The essay will also suggest a resonant stone typology and discuss the necessity of one. Finally, the intention is also to shed new light upon the discussion on what the uses of the ringing stones might have been..
Metoder för att undersöka effekterna av naturvårdshänsynen i skogsbruket, efter den senaste skogsvårdslagenMetoder för att undersöka effekterna av naturvårdshänsynen i skogsbruket, efter den senaste skogsvårdslagen.
In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.
Internmarknadsorientering : Förutsättningar för effektiv intern marknadsföring
Internal marketing has been proposed as a means of gaining competetive edge in a market where service quality is an important precursor to performance. Still, the practical application of internal marketing remains relatively limited, which is hypothesized to be partly attributable to a widespread lack of the required philosophy which facilitates the effective implementation of internal marketing. The concept of internal market orientation (IMO) has been proposed as an accurate representation of this philosophy. This thesis attemps to assess the relevance of an IMO in relation to the internal marketing activities of an organisation. The findings of the study imply that IMO related activities impacts the effectiveness of internal marketing and that it thus provides a valuable tool in the process of implementing internal marketing strategies..
Genetic variation of ASIP and MC1R in past and present sheep of Gotland
Ovine black coat colour is determined by the MC1R (Melanocortin 1 receptor) and ASIP (Agouti signalling peptide) genes at the Agouti and Extension loci. The black phenotype is caused by production of eumelanin by melanocytes, whereas yellow-tan or light phenotype is the result of phaeomelanin synthesis. The ovine MC1R gene has two known alleles: the wildtype (E+) and the dominant black (ED) alleles. Two missense mutations (c.218T>A and c.361G>A) constitute ED. The presence of a third allele, the e allele, is proposed and believed to give rise to phaeomelanic phenotype.
Jämställdhet åt skogen?! En studie som utreder anledningarna till att kvinnorna slutar som skogsinspektorer
The forest owner cooperative has observed difficulties with keeping women as forest advisers/ buyers. This is a problem because the organisation wish to have both men?s and women?s qualifications. The organisation?s purpose in their equality and multiplicity plan is to increase the knowledge and awareness of equality and multiplicity, increase the credibility to the members and customers, and to be well prepared for the future need of qualifications.
The purpose of this paper is to identify if there are any conditions that may limit female employees at this particular service.
Härliga hagar och skrämmande skogar : om våra känslor för landskapet och vad de beror på
Do our imaginations of real landscapes get affected by works of art such as paintings, myths and literature? They often give very colourful descriptions in words as well as pictures. Do they actually change our feelings for the landscapes we are in and carry around as images inside?
Close your eyes and take a few deep breaths. Imagine that you are leaning against a wooden fence a mild summer evening.
Är bor nödvändigt vid skogsgödsling i Sverige?
This thesis has been made on behalf of SCA Skog AB to assess the need of boron in Swedishforest fertilization. Boron has been added to Swedish forest fertilizers since the beginning of the1980s. This makes the fertilizers more expensive and therefore has the necessity of boron inSwedish forest fertilization been raised.The Swedish bedrock generally contains small amounts of boron. The boron in the bedrock istightly bound to the mineral tourmaline and mostly unavailable for plants. This leads to that thecontribution of boron to the soil from weathering is very low besides soils with marinesediments.
Val av område och områdesskydd för Natura 2000 med skogshabitat : En jämförande studie av fyra län i Sverige
The Natura 2000 Network is one of the European Unions many tools concerning nature conservation, and is without comparison the premier contribution when it comes to halting the loss of biodiversity. This essay is a case study on how the regional work with the Natura 2000-network has been carried out in four different counties. These counties are Södermanland, Västernorrland, Jämtland and Örebro. They have been compared based on the theoretical concept of sustainable development. This essay describes how the officials in the County Administrations view the regional implementation of Natura 2000 when it comes to the selection of Natura 2000-sites with forest habitats and the creation of an additional protective measure.
Planering av väginvesteringar :
The problems around and the planning of wood flow is some of the most complex issues in the forest-sector. The experience and overview of the single employees is crucial for the possibility of correct tactical and economical decision-making. The increasing demand of savings and shorter reaction-times with greater flexibility in the wood-supply-chain, makes solutions and aids for improved effectiveness in the work and processes according to wood-flow urgent.
Holmen Skog is starting to develop a new forest-road-management-system. The system will facilitate the work according to construction, improvements and updating the standard of roads.
