This study was conducted in the "Kåtaberget" forest reserve in Västerbotten in the summer of 1999. In the summer of 1995, a prescribed burning was performed in the reserve. In some places where coarse dry woody debris (logs and stumps) was present, the fire consumed the wood, as well as parts of the humus layer, creating deep-burned patches. The low intensity ground fire also created dead woody debris by burning off living trees with open fire scars, as well as standing dead trees. In this study, the post-fire tree seedling establishment was examined, with special attention given to the former presence of woody debris. The study also includes a survey of the areal extent of deep-burned patches, as well as an examination of tree seedling establishment in these patches, compared to other burnt ground.

In my thesis I have sand blasted different type of woods - ring-porous and diffuseporous deciduous tree species and conifers - to show different results depending on the species, the direction of the grain and the effects of surface treatment of a blasted surface.The results of my tests were sometimes unexpected, such as that the sand from blasting almost completely disappeared, that all wood surfaces after blasting exhibited a much lighter or paler surface than before and that the diffuse-porous tree species showed differences in hardness between the beginning and end of annual rings.By creating a library of different kinds of wood and sandblasted surface treatment, I have created a reference bank that I will be able to use me in the manufacturing of interiors, furniture and other objects..

When the storm Gudrun hit Sweden on the 8th and 9th of January, many recreational forests in southern Sweden blew down. For this reason there is a demand for new regeneration methods as to how these storm-felled areas should be regenerated and with what species. In this study the forest is divided into three areas: production, recreation/production and recreation. The first area is a forest with production as main goal and these kinds of forests are located a bit from the city. The second type ? recreation/production forest ? has two equal goals: production and recreation, and is located close to the city.

This is a 15 hp (10 p) thesis in biology at the programme for Horticulture Management at the Swedish University of Agricultural Sciences, Alnarp. In this literature study we have processed, reviewed and arranged facts and research, to make it more available for those who want to know more about establishment or cultivation of mosses. Our client is Fredriksdal?s Museums and Gardens in Helsingborg who are planning to establish a moss garden. The information is meant to be used by Fredriksdal and other similar facilities.

The purpose of this study is to give a description of how six pedagogues in the third and fourth grade teaches mathematics and which working methods they use. When using the term working methods it is implied that it can for example be outdoors pedagogic, laboratory material, problem solutions et cetera. This material can both be an everyday material or a pedagogical material. The research was carried through by interviews and observations. Six pedagogues were interviewed in two different districts.

I examensarbetet ÄGG har jag testat att anända en sökande och experimentell inställning till textila material och tekniker som utgångspunkt för att formge en kollektion plagg. Som inspitration och utgångspunkt för arbetet med material och teknik har jag använt mig av ägget, dess material och funktioner..

This Master's thesis work was done at SLU, Uppsala, Sweden in cooperation with Upplandsstiftelsen and Uppsala County Council. The studied area is pointed out as an area for EU´s LIFE project, NATURA 2000, concerning the Scarabid beetle Osmoderma eremita. The studied area lies in an agricultural landscape rich on deciduous trees, about 15 km south of Enköping in the County of Uppland. The species is dependent on large, old, hollow trees, which are exposed to sunlight, usually oak trees in this area. I studied the area in detail concerning large old trees (>70cm ø), middle-aged oak trees and young oak trees.

Syftet med mitt examensarbete var att få mer kunskap om konkreta material som behandlar multiplikation och division. För att få veta vilka konkreta material som finns att tillgå gjorde jag intervjuer med två lärare som fick beskriva vilka material de använder sig av. Jag valde att observera två elever enskilt då de löste de multiplikations- och divisionsproblem som jag hade designat för studien. Det jag fick ut av undersökning var att det finns många olika material som elever kan arbeta med samt att det är viktigt att de får möjligheten att arbeta med dessa material. Jag kom fram till att lärare bör vara medveten om i vilket område som materialet är bäst tillämpad och att elever behöver använda sig av konkreta material för att lättare förstå uppgiften.

Syftet med examensarbetet är att ta del av förskollärares åsikter om och erfarenheter av materialets betydelse för barns lek och lärande, med fokus på ?smutsigt? material i innemiljön. ?Smutsigt? material är material som kan skapa oordning och kladda ner, t.ex. vatten, sand, lera, färg m.m.

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.

Birch is the dominant deciduous tree species in Sweden but only 16 % is found in pure birch stands. The majority of the birch (51 %) is to be found in conifer dominated stands. Swedish forest land comprises approximately of 23 % mixed stands and one problem is that for mixed stands there are few management recommendations. The underlying aim of this thesis was to study the management of mixed forest stands of spruce and birch to achieve good timber quality of birch. The study was based on a literature study and measurement in a field experiment launched in 1998 by the Swedish University of Agricultural Sciences (SLU).

Detta examensarbete omfattar produktutvecklingen av en komponent till en mätutrustning som ska mäta flytbarheten hos smält metall. Arbetet har utförts hos Bryne AB och har lett fram till koncept-, material- och tillverkningsförslag för komponenten. Arbetet har även utvärderat ett för gjuteribranschen nytt formmaterial som alternativ till dagens gjutsand. Tester har gjorts för att se om återvunnet (material x) går att använda som formmaterial till högtemperaturapplikationer..

Syftet med detta examensarbete var att undersöka hur lärare använder olika laborativa material i sin matematikundervisning i år 1-3 och hur detta överensstämmer med det sätt som upphovsmännen till materialen avser. Mina frågeställningar har bland annat varit: Vad är laborativa material?, Hur använder lärare laborativa material i matematikundervisningen i år 1-3?. För att söka svar på dessa frågor har jag genomfört en litteraturstudie, och en kvalitativ intervjustudie med åtta lärare som använder laborativa material i sin matematikundervisning. Resultatet visar att det finns skillnader mellan hur lärare använder vissa laborativa material och hur materialens upphovsmän beskriver att materialen ska användas.

The purpose of this study was to examine how teachers act when it comes to play with constructions in preschool. The purpose was also to find out what kind of material the children have to work with and what they do with the things that the children made. The study was based on qualitative semi-structured interviews. Semi-structured interviews was choosen  to get out as much information as possible, with open questions in a semi-structured interview you can get the information that is relevant for the study. The results show that there are different kind of material available in preschool, but knowledge of the subject is missing and demanded by teachers. The material are pretty similar, some of the teachers use material from the forest while others don?t.

Under de senaste åren har intresset för användningen av laborativt material ökat markant. Syftet med denna studie är att ta fram och göra en jämförelse mellan lärare och elevers uppfattningar och åsikter angående användningen av laborativt material i matematikundervisningen. Studien har genomförts på fyra lärare i Örebro samt deras klasser i årskurs 5. Resultatet visar att laborativt material underlättar lärandet, gör matematiken roligare och mer intressant, för många enligt både lärare och elever. Lärarnas och elevernas uppfattning om hur ofta laborativt material plockas fram och då finns tillgängligt skiljer sig åt.
