Identifiering av fel i skogliga beståndsregister med hjälp av satellitdata :
This thesis has focused on the possibility to use a satellite image method developed by Metria Mijöanalys to identify stands that are wrongly registered in Holmen Skogs database. The method is only intended for identifying stand with poor descriptions in Holmen?s database that needs to be updated and not for updating the stand information.
The study area is located several km west of Hudiksvall on the borderline between Gävleborgs- och Västernorrlands län. The area is covered by a SPOT image from 2005. By which Metria Miljöanalys has made estimates of forest parameters for all stands in the area, and compared them with corresponding estimates according to the stand database.
Hästars aktivitet och liggtid på madrasserade gummimattor i box
Sleep is essential for all mammals and they all have different sleep patterns. Wild horses normally spend 2-8.5% of a 24-hour period in recumbent position while stabled horses lie down 11-20%. To fulfil the need of rapid eye movement (REM) sleep the horse must lie down with support against the ground for the head. The lying behavior can be affected by external stimuli such as age, food intake, bedding materials and if the horses feel safe or not. This study investigates the lying behavior of horses on different bedding materials; wood shavings and filled rubber mats (HIT SoftBed®).
Friidrottsungdomars fysiska kapacitet över tid : En retrospektiv studie av intagningstesterna vid friidrottsgymnasiet i Växjö mellan åren 1982 ? 2009
Background: Today when leisure time is spent, spontaneous sports activities decrease, due to a more comfortable way of living and physical capacity among non active adolescents decreases. There for it´s interesting to see how the physical capacity level has changed over time among young people participating in organized leisure time sports.Studies around the world show that young people standing outside organized sport activities have tended to decrease their physical activity levels over the last few decades. Less leisure time is spent doing physical activity and sometimes gets put into context with increased time spent behind the computer or inactivity.Design: A retrospective study of the test results on physical capacity between 1982 and 2009 for students applying to Växjö track and field high school. A total of 635 students (15 years old) have done 11 physical tests during the years. Five of these tests, with enough participants (at least 100) and documentation over at least 10 years, were used in this study.Results: This study shows that young track and field athletes have maintained the same physical capacity from 1982 to 2009.
Marknadsundersökning om markägarens val av skogspartner
The driving forces from the forest owners point-of-view was studied on a market where several buyers attend to procure round-wood. It was concluded that forest owners prefer personal contacts to other means of communication, but that it is essential that the initial contact is a personal letter on paper. Furthermore, although price is always important, long standing relations is asked for. The buying companies need skillful experienced buyers that can provide more than just quick closures of deals..
Simulering av hydrauliska dämpare i borrslagverk
This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process.When the models had been created the rock model was evaluated by comparison with measured values from lab tests. The verified rock model was then used to evaluate the shock absorber models.Four new shock absorber concepts have been developed. Three of these have been modelled, while the fourth have only been sketched and described.The evaluation of the models showed the following:? Simulations of the single shock absorber don?t correlate to reality very well.
Metod för urval av bäriga bestånd längs med bäriga vägar i Sveaskogs planeringsområde Råneå och Överkalix :
With increased need for flexibility in timber deliveries, forest roads become an important factor. The disintegration of roads during the spring season can be avoided if it is possible to rule cutting areas to stands with good carrying capacity along roads with good carrying capacity.
The goal with this work was to create a method to find the stands with high carrying capacity located near roads with high carrying capacity, and select them into a collection file. The method was based on Esri ArcGIS 9 and the tables that follow within that program.
The method resulted in four different themes:
1. Collections with GYL 100 that cross the bufferzon for 0, 1, 2 and 3 class roads. Result 36 collections.
2. Collections with GYL 100 and 200 that cross the bufferzon for 0, 1, 2 and 3 class roads.
Vilka är dagens krav på gårdsverkstaden? :
After been told that an ordinary winter service for our combine should cost more than
20000 SEK, not included spare parts, I decided to write this paper about today?s
requirement of the workshop on a farm. I think that the lack of proper premises is the
reason way not more of the ordinary machinery maintenance or upkeep is performed on
the farm.
When I did my literature survey I found that the Swedish environmental code, set by the
Swedish law regulate how drain or sewer should be built. The environmental code
however leaves a lot for your own interpretation. It might not be so bad but it must be
very hard for the local environmental office to interpretation the regulations, since they
are the ones that gives permission for the sewer in your workshop.

EFFEKTIVARE UTLASTNING FÖR LAGER UNDER HÖGSÄSONG PÅ HUSQVARNA AB
Husqvarna AB operates two warehouses located in the area of Jönköping. The most important task is to manage the large volume fluctuations during the peak season. DHL Exel Supply Chain (DESC) run the warehouses and the domestic transportations is outsourced to DHL Express. A number of forwarder agents are responsible for distributing the export gods. In the present situation a bottleneck occurs at the warehouse loading section, and the consequence is fulfill the time of delivery for all customer orders.
Detaljhänsyn efter slutavverkning : kvantitet och inverkan på framtida produktion hos SCA i Västerbotten
According to FSC (Forest Stewardship Council) shall at least a mean of 10 trees per hectare including riparian zones and other areas with high biological values be left in final felling. In addition large clear areas should not be created and all retained trees with high environmental value shall be spared. To leave trees in final felling means a lower cutting volume and hence a lower income from the cutting, but it also means that the production in the next generation becomes less because of competition. The aim of this study was to evaluate the effect retained trees have on the production in the new generation of forest, and to investigate if there is any way to lower this effect. The environmental care has also been estimated by the amount left in final felling.
Finns det någon variation i CMJ som återföljs av förändringar i någon av pulsvariationerna och handstyrkan?
IntroductionSuccessful training is a key for athletes to make progress in their development. Training must not just involve overload, but also must prevent the combination of excessive overload plus inadequate recovery. Athletes can experience short-term performance decrement without severe psychological or lasting other negative symptoms. Too much hard exercise or too little sleep can cause overtraining, a condition in which the subject can prevent to be away from the sport for several weeks or months. Previous studies have detected that it is important to avoid overtraining.
Val av liggplats och väderskydd hos dikor vid utedrift vintertid
If you keep cattle in a herd outside all year round on big varying grounds, their possibilityto perform their natural behaviour increases. This way of keeping cattle requires that youprovide them with their other needs, like shelter and a dry and clean resting place.According to the animal welfare authority´s regulations on livestock farming, only animalsthat are suited to stay outside during the cold season are allowed to be kept outside. Theyshould also have access to a shelter or another building that gives them protection from theweather and wind and provides a dry and clean resting place.Research has shown that as long as cattle do not get exposed to precipitation and wind theywill manage low temperature well. Some of the things that will affect how well the animalshandle different climates are the isolation ability of the fur, the animals´ body size and thefeed intake. A dry lying place that is both insulating and moisture absorbent is also of greatimportance.
Fri utfodring av halm som strategi för att förhindra stereotypier hos uppbundna kvigor :
At present indoor tethering of dairy cows is still common but is not predicted to take part of modern dairy production. When conducting scientific studies of cattle it is generally necessary to tether the animals to maintain a controlled environment. Studies confirm that tethering and confinements of cattle severely affects the development of stereotypies in cattle. The feeding regime and feeding level have an immense affect on the stereotypi level in cattle.
The aim of this experiment was to study dairy heifers that had never been tethered before the start of the experiment, to evaluate the affect of tethering on the development of stereotypies and the impact of the feeding regime on the behavior of the animals.
Sixteen dairy heifers were tethered in a tie stall and divided in two groups with different treatments. Heifers in treatment E were fed restrictedly with silage and treatment EH was fed with the same amount of silage but also straw ad libitum.
Samiskt skogsutnyttjande, dimensionsavverkningar och naturvärden : skogshistorisk analys i block 5, Pakko kronopark i Norrbotten
In order to understand the human impact on today?s remaining ?virgin? forest and to develop sensible management strategies for future reserves, it is necessary to know how these forests have developed. This knowledge can be gained by using forest history analysis. here are large areas of forests still untouched by modern forestry in the mountainous region in the county of Norrbotten. These forests are highly interesting study objects from an ecological and historical point of view.
Profitability of Momentum Strategies on the Nordic stock market
Purpose: The main purpose of the thesis is to examine the profitability of Momentum Strategies on the Nordic stock markets. This will provide insight and contribute to the debate on efficient markets. Finding profitable Momentum Strategies will provide strong evidence of inefficiency in the market. A secondary purpose is to examine factors which might cause or impact the profitability of the Momentum Strategy. We will look closely at the relationship between the profitability and factors such as risk (CAPM-beta), market capitalization, trading volume and seasonality.
