Nedbrytning av vägar: Jämförelse mellan axlar med singel- respektive tvillingmontage
When designing roads it?s important to knowwhat loads will bedriven on it. The axles on heavy vehicles can either have super single tires ordual tires which, according to studies, damage the roads differently. The SwedishTransport Administration is developing an understanding for the character ofthese different kinds of axle and tire types on the loads induced on Swedishroads. In this thesis a field study was conducted to determine the distributionbetween axles with super single tires and axles with dual tires on heavy vehicles.A highway, a country road and a national road were investigated during thestudy.
Några svenska virkesaktörers system för skoglig planering
The purpose of this degree project is to give an overview of the planning system of four Swedish forest companies. The involved companies are ATA TIMBER, SYDVED, BERGS SKOG and VIDA SKOG. The study is based on information from a literature study and by interviews with personals from the four companies.
Each company is described to get a better insight of the companies work and what potential they have. The description of the planning process comes after that. The companies are described separate from each other and will be compared later in this essay.
Grundvattenavsänkning vid tunnelbyggnad ? tillämpning Förbifart Stockholm.
Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

Svenska sojabönor - finns marknadsmöjligheter?
The large-scale soy cultivation has negative consequences for the habitat of local populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.
Lövskogsmålen i FSC-certifierat skogsbruk : tolkning, uppföljning och skötseldirektiv
Den mest eftertraktade råvaran i svenska skogar är barrvirke och detta har sedan länge varit vägledande för skogsbrukets planering och skötsel. Brandskydd, ökat betestryck och skötsel för barrträd har missgynnat lövträden. Eftersom lövskogar i den boreala zonen tillhör ett av de artrikaste ekosystem är kontinuerlig förekomst av lövträd och lövdominerade bestånd viktigt för den biologiska mångfalden. Den standard skogsägare certifierade enligt FSC (Forest Stewardship Council) har att följa innehåller två lövindikatorer, 6.3.8. och 6.3.9..
Bakgrund - No?t - Lycka : en genomga?ng av musikens betydelse i mitt liv samt arbetsprocessen fo?r musikskapandet
The Swedish social insurance agency provides financial support for families and children, but also for people with work injury, illness and at old age. During 2012 they saw the amount of notifications of insurance increasing in Sweden, which is a development that cost our society a great deal of money. With the aim to pursue a sustainable development I have therefore devoted this project to wellness and stress management within preschool.The employees of preschool are often dealing with a lot of stress, due to the big groups of children that causes high noise and sound levels. The high noise and sound levels is a contributor to stress which additionally can damage the health and cause impaired hearing loss. About half of the people around their forties until the age of retirement have difficulties understanding speech in large groups.The purpose of this project has been to investigate the causes of negative stress for my target group, women between 30-60 years old who works in preschool.
Utvärdering av CTI på virkesfordon : ? CTI-projekt Holmen Skog/Örnfrakt 2005-2006
The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility
Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure.
The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.
C16 - utveckling och metod
Intresset för bioenergi bara ökar. 2008 var den totala energianvändningen i Sverige 497 terawatt timmar (TWh), varav 125 TWh (25 %) kom från biobränslen (Elofson, 2009). Under de sista åren har utbudet av och intresset för biobränslen ökat och också möjligheterna att tillvarata och använda dem.
Arbetet har som syfte att: 1) Presentera resultaten i Sverige från användare av C16, 2) Presentera resultaten för olika användningsområden, 3) Beskriva marknaderna i England, 4) Presentera resultaten gällande maskinkostnader och tidsstudie. Detta visar en bild av C16 och de kunskaper och erfarenheter som finns av aggregatet.
Maskintillverkaren Bracke Forest som etablerades 1922 och har flera produkter anpassade för aktiviteter i skogen. Företaget investerar mycket pengar på forskning och produktutveckling.
Skogsvårds och bioenergiaggregatet, C16, används idag till många olika arbetsuppgifter och i många olika länder.
Hunter demography, trends and correlates of hunting participation in Sweden
The concerning issue of declining number of hunters in North America is also apparent in Europe and Sweden. When the bulk of research found on human dimensions and hunting participation has almost exclusively been done in the United States, this report seeks to add to the needed knowledge on a national level focusing on the causes of hunter declines related to social factors within Sweden. Using hunter data reaching from commune, county to National level, this report describes the correlation between a number of variables and the hunting participation in Sweden.The typical Swedish hunter lives in an area with low population density, the person usually has higher education, the living situation is stable with no recent moving and there is relatively good access to forest land. Persons with weaker connection to the Swedish culture such as foreign citizens, people with foreign background and people born outside ?the Nordic countries? are less likely to start hunt or participate in hunting.A strong relationship was found between the favorite game, moose (Alces alces), and the amount of hunters participating in the hunting.

Simulering av översvämningar i Byälven
Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.
