Tickor på död ved
I dag råder det brist på död ved i Sveriges skogar. Detta på grund av det intensiva skogsbruket där man kalhugger och plockar bort all liggande ved. Dock är det viktigt med många döda träd i olika nedbrytningsstadier för många skogslevande arter. Svenska skogar har få urskogar där naturliga avdödningsprocesser av träd får ske och därför minskar den biologiska mångfalden i skogen. Tre arter som endast trivs i naturskog är tickorna ullticka, Phellinus ferrugineofuscus, gränsticka, Phellinus nigrolimitatus och vedticka, Phellinus viticola.

Food preference in African Elephants (Loxodonta Africana) and the impact of Bomas in the vicinity of and in Masai Mara National Reserve
In the Maasai Mara National Reserve the native people, the Maasai, have lived for a long time following their own traditions. Their traditional lifestyle is that of a nomadic people, leading their cattle to the best grazing. Sharing their land with a large variation of different animals, one of them being the African Elephant (Loxodonta africana), the Maasi people have since long adapted to a life side by side with these giants, as well as the fierce predators living in the area.The aim of this study is to determine whether the Maasai settlement, known as Boma, has any impact on the elephants in the surrounding area. In order to conclude whether the bomas has an impact or not, observations of the wildlife were carried out. Observations were conducted in two different seasons, in December 2003 and May/June in 2004.
Strategisk och taktisk planering samt länken där emellan : analys av planeringsprocessens genomförande vid SCA Skog
To effectively manage a forest resource for both economic and other values good planning is required. The problem is complex since you want to know which forest to cut and when. Often a hierarchical planning structure is applied, including strategic (long-term), tactical, (medium-term) and operational level.
Today SCA Forest is one of few forestry companies in the northern Sweden with an integrated forest wood supply and industry. The goals of the company are to supply their own industries with wood and to manage the resources of the forest through a long-term perspective with satisfactory profitability.
OMBYGGNAD AV TRAFIKPLATS : Ekhagsmotet i Jönköping
We have the tradition in Sweden to build villas and houses with a wooden framework. It has become natural for us because we have so much forest in our country. Building with wood has advantages, it is easy to process, but also disadvantages, as it is sensitive to moisture.Finland has long made use of the thermal blocks to build villas. It is a type of bricks that are a bit like a sandwich element, with a core of EPS and concrete on both sides of the core material. The concrete is hollow, so that after the walls has been bricked up you pour concrete into the hollow bricks.The issue of this report is to find out if concrete can be an alternative to wood as framework material in villas.
JAS för jobb : JAS-projektet som industripolitiskt medel
The purpose of this paper is to examine how the target to convert the Swedish military aviation industry towards working within the civilian sector was planned and implemented parallel to the target of building a world-class military aircraft. A number of Government bills have been studied, bills directly connected to the JAS-project as well as bills dealing with civilian project ?s for the military aviation industry. The first group includes bills dealing with the JAS-project ?s role in the overarcing defence policy, as well as the Government ?s bill specifying the guidelines for the JAS-project.
Var man slipad förr? En experimentell undersökning av sandpapprets föregångare.
In this essay I have looked more closely at different means of grinding wood prior to the mass production and total dominance of the sandpaper in recent times as there is virtually no information to be found about this. I have also done a few replicas of how early sandpapers might have looked and as a part of creating these replicas I have also tested diffrent types of early glues. The conclusion of it all is that all the alternative grinding materials tested workd virtually as well as modern sandpaper, with some reservations. And the replicas, although rough, worked mostly well despite being constructed with simplicity in mind. This indicates that an artisan could easily construct sandpapers if he so wished..
Ekonomi eller politiska beslut : Vad styr fristående gymnasieskolors lokalisering?
In the beginning of the 1990s the responsibility for the schools shifted from the government to the local authorities. This started an era with a freedom of choice for students where they themselves could choose which school to go to. The new system also opened up the possibility for independent private schools to exist side by side with local authority held schools. The overall aim of this study is to determine the factors that affect the location of these independent schools and the geographical pattern these independent schools create. The study in this paper is based on materials from statistics and interviews.
Logistik för stråbränsle :
Summary
Today energy prices are rising. As a result biomass fuel is getting more and more
interesting. Wood chips is very popular, but also straw from grain production is on the
table. Lunds Energi AB project a combined power and heating plant in Örtofta out of
Lund. Wood chips is meant to be the main energy source, complemented by straw.
In this thesis the transportation of straw for fuel is studied.
The Swedish forest industries' view on the future market potential of nanocellulose
General concerns about environmental issues may mean that the demand for bio-based products will increase. Opportunities that arise on markets, together with the declining demand for newsprint, may trigger firms in the Swedish forest industry to increase their development of new products. One product that has received a lot of attention during recent years (and is a contender) is nanocellulose.
The purpose of this master thesis was to examine the Swedish forest industry?s view on the market potential of nanocellulose.

Project EQS - Elektronisk växelreglering för motorcykel
Husaberg Scandinavia AB is a company producing and developing a range of motorcycles for both on- and off-road use. Husaberg provided the project group with a task of developing an entirely new way of operating the sequential transmission that can be found in today?s motorcycles. The target was to bring the product from idea to a functional prototype ready for further tests. Operation of the motorcycles transmission is today made by a foot pedal placed on the left hand side of the bike.
Alter ego : Ett föränderligt bord
Projektet har gått ut på att göra ett flexibelt bord som ska kunna gå att förändra mellan högt och lågt och mellan olika storlekar på bordsskivan. Detta som en funktionell aspekt av föränderlighet men jag ville även införliva en emotionell föränderlighet. Jag vill att användaren, på ett handgripligt sätt, ska kunna uttrycka sig själv i bordet. Min intention är att man, genom att göra sitt eget unika bord, skapar ett starkare band mellan artefakt och dess användare. Detta som ett led i en hållbar utveckling så att produkterna vi äger kan brukas längre och motverka den ohållbara så kallade slit-och-slängkulturen..

There aretwo possibilities either traditional gypsum board or gypsum-based self leveling underlayment.The roads around the construction site are narrow. A regular twenty-five meter long truck has nopossibility to reach the site. The construction site is small and the storage area is limited.
Konceptframtagning av testinstrument för vattendetektion baserad på MIP
Water is vital for all life on earth. But it can also be dangerous, even fatal, if it is polluted water. 60 percent of child mortality can directly be deduced to dirty water. Not only developing countries are affected, even in the western world epidemics are breaking out by partake or bathing in dirty/polluted water.MIP, Molecularly Imprinted Polymers, is a biosensor technology that can provide faster and more reliable response than the current methods of water analysis. It is also cheaper and due to that more samples can be taken and analyzed.
