Vad ridskolor lär ut om hästens beteende
The horses have been in the care of humans for about 5000-7000 years. But even though the horses have been domesticated and artificial selected for such a long time their natural behaviours and instincts still remains. In the rich countries there are many people who have the opportunity to ride either on their own horses or at riding schools. Many of these people have not grown up on farms and have no experience of handling big animals. This can lead to implications of the horses? welfare.
Produktivitet och lönsamhet vid skogsbränsleuttag längs skogsbilvägar :
With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.
Migration och vegetationsupptag av radiocesium i åkermark - en långtidsserie av mätdata samt en långsiktig simuleringsmodell :
Abstract
The accident in 1986 at the nuclear power station in Chernobyl, Ukraine, dispersed radioactive cesium over large areas of Europe. The half life of 137Cs is 30 years and this radionuclide also behaves like potassium, which means that it can easily be taken up by the vegetation or be adsorbed in to the structure of clays, principally illitic clays. When radiocesium decays ionizing radiation is emitted, which is harmful to humans that are exposed, either directly or indirectly through food intake. It is there-fore important to know what happens to the cesium that is dispersed into the environ-ment.
In this project a simulation model was constructed to simulate the adsorption and transport of radiocesium in the soil and plant uptake.
Pedagogiska miljöer : Barns och pedagogers uppfattningar om den pedagogiska miljöns erbjudande utifrån ett genusperspektiv
Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.
Våldtagen eller inte? En studie kring professionellas syn på den våldtagna kvinnan och den rättsprocess hon genomgår
Many sexual crime matters are in a difficult position when it comes to proof, where it's word against word between the parties. However, the legislation states that it's the offender's actions that are to be in focus for the judicial judgement, but often the focus is on the woman, whether she said no and how she acted in that particular situation (Sutorius & Kaldal, 2003).The purpose with this essay was to investigate the professionals' view of the raped woman and what image the professionals convey/construct of the legal proceedings she goes through. With professionals, we mean lawyers and other professionals that function as support or treatment contacts for raped women. The questions we considered to be relevant for our investigation were: What image of the raped woman do the professionals convey? What image of the crime rape do the professionals convey and what image do they convey/construct of the legal proceedings the woman goes through? How is the view of the raped woman constructed in society? We considered qualitative interviews mixed with earlier studies and theories to be the best investigative method for our purpose.
Ekoturismens natur- och miljöpåverkan i polarområden
Tourism in the Arctic and Antarctic is increasing rapidly. In both Polar Regions, the cruise tourism is predominant. Several of the tour operators arrange trips under the banner of ecotourism, meaning that the trips should be ecologically sustainable. To ensure ecotourism standards there are different types of certifications; for cruise travels in the Arctic there is AECO (the Association of Arctic Expedition Cruise Operators) certification, and for travels to the Antarctic IAATO (the International Association of Antarctic Tour Operators). Promoters of ecotourism argue that these trips are important because they create support for conservation work among tourists making them ?polar ambassadors?.
Clear-cut and substrate characteristics important for the occurrence of the beetle Upis ceramboides
Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. The aim of this study was to see which clear-cut characteristics are important for the occurrence of the saproxylic beetle Upis ceramboides.
This is a species favored by open habitats and is said to respond positively to forest fires. The distribution area in Sweden for this species has decreased during the last two centuries and I wanted to see if there were differences between clear-cuts in Hälsingland, where it is very
rare and decreasing, and Norrbotten where this study was conducted.
Naturupplevelse och psykisk hälsa : Hur påverkar naturupplevelser människor med stress- och utmattningssymtom
Stress-related diseases in Sweden have doubled since 1997. Even longterm sickness related tostress has increased over the last decade. In future there is a need of alternative methods todecrease the amount of people being affected to gain a better population health. Natureassisted therapy (NAT) was shown to be a successful method as part of the therapy of stressand burnout likewise was nature an important factor to prevent people from mentaldisorders. The aim of this study was to analyse the latest research concearning nature and itshealth effects with focus on stress and burnout patients in order to plan health promotingactivities outdoors for these patients.
Behaviours of wild male and female Colobus angolensis palliatus during morning and afternoon in Diani Beach, Kenya
Colobus angolensis palliatus is a small old world monkey inhabiting southern coastal Kenya to southern Tanzania. The species activity budget is known to vary between seasons and areas, probably due to differences in group sizes, diets, predatory presence and resource competition. The variations between male and female activity budgets are reckoned to be a result of pregnancy and lactation. The aim of this study was to investigate potential differences in behaviours between morning and afternoon periods and between males and females. The study was carried out in two forest fragments in Diani Beach on the south coast of Kenya.
Identifiering av konfliktbestånd med hjälp av laserskanning
The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
Hallsta Pappersbruks virkesförsörjning
Competition of spruce fiber raw materials has increased dramatically in the last few years, leading to the fact that transportation costs in the current situation represents a much larger share of the total raw material cost. The Holmen-owned pulp industry Hallsta Paper Mill's location on the coast also constitutes a problem, because of the lack of raw material, which is much larger there, than for a pulp mill located in the hinterland. For a coastal industry it?s therefore natural to import much of the raw material by boat or to buy it from the timber terminals, in order to maintain good profitability. The purpose of this study was to analyze how the size of Hallsta Paper Mill timber supply area, without competition, with competition and with terminal use, affects the company ?s transport costs.
Kapitalbudgetering och ekonomisk styrning : En fallstudie av svenska skogsindustrin
Bakgrund: Investeringsbeslut är ett av de viktigaste besluten som tas av chefer i företag. Besluten grundar sig på investeringskalkyler, som ryms inom begreppet kapitalbudgetering. I företagsekonomisk litteratur beskrivs sällan samband mellan kapitalbudgetering och annan ekonomisk styrning, vilket innebär att det finns ett tomrum inom forskningsområdet. Syfte: Syftet med uppsatsen är att beskriva hur företag inom den svenska skogsindustrin utformar och använder kapitalbudgetar som beslutsunderlag samt utreda och förklara sambandet mellan kapitalbudgetering och annan ekonomisk styrning. Metod: I studien har kvalitativ metod och fallstudier använts.
Älgexplosionen på 70- och 80-talet, ett hot mot sågverket?
The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber.
The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development.
There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

Omkonstruktion av armled tillhörande Bracke Forest högläggare
One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.
