Betydelsen av skogens ålder och förekomst av lavar för renars val av vinterbetesområde :

This is a study on winter groups, ?siida?, of semi-domesticated mountain-migrating reindeers that move to lichen pastures in the lowland boreal forests during winter. The aim of the study was to determine reindeer habitat use in their winter ranges in a managed forest landscape. The reindeers use of three different types of forests was determined, 1) 100-130 year old, 2) 20-40 year old forest and 3) clear-cut areas. All sites were dominated by Scots pine, Pinus sylvestris, and had the same types of ground vegetation.

Verktyg för utveckling av terrängparker inom skidanläggningar. : Shaper

Today we can create digital 3D models which can be realised almost instantly through production methods such as 3D printing and computer controlled milling.What if this same technology could be applied to the development and construction of terrain parks?With Snow as the material tools could be developed using similar principles to design and sculpt the surface, only on a larger scale.How would terrain park designers adapt their process to use this new technology? In this Industrial design thesis I explore how the ideas of the terrain park designer can be expressed through such a system with focus on the designers knowledge and skill without the need to learn complicated 3D programs.Sketch, create, ride. .

Giraffens blodtrycksreglering

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.

Konstruktiv utformning av vikplog

This project is about investigation and improvement of a V-plow for the company Swekip. A V- plow is used for Snow removal but this product has been found to have deficiencies in its construction, breaking down and not living up to the desired objectives. This is because the product is ordered from a company in China where they have some problems with understanding the purpose of the plow.Initially the existing plow is investigated, all the shortcomings set out and examined, what is wrong and what needs improvement?When the solutions were done they were evaluated and examined that they actually live up to the desired requirements.This assignment is a pure construction project where the majority is implemented in CAD, where models are developed and FE analyses are carried out. But the project also includes a feasibility study, idea study and hydraulic design.The results are presented in the form of a CAD model and associated drawings that will serve as the manufacturing basis for the new V-plow.

Älgbetesinventering på Orsblecks viltvårdsområde

The purpose with this report is to compare moose browsing in young stands within a small game preservation, and if there are any differences between two areas. The method used in the inventory is a local damage caused by moose browsing survey. It is suitable on areas that have more than 50 hectares but less than 250 hectares of young forest. Inventory of moose browsing is best done on bare ground in the spring and should preferably be done before the flushing begins at the pine. Orsblecks game management area is divided into two different moose management areas, Noppikoski and Siljansringen. During the winter Siljansringen has a denser winter strain of moose, because of the moose seek out lower parts with less Snow during the winter. This should also lead to the southernmost part should accommodate larger proportion of damages caused by browsing by moose.

Eurokoder : en jämförelse mot BKR

In Sweden there are currently two separate guidelines you may use whenperforming calculations on frameworks, BKR and the Eurocodes. Although at theend of 2010 you are not allowed to use BKR any longer and only the Eurocodeswill be viable. The aim of this thesis is to explain how the Eurocodes and EKS work and alsohow they compare to the current guideline BKR. Similarities and differencesbetween these guidelines are also discussed so that the reader will get a betterunderstanding of how the Eurocodes are applied. The areas discussed are asfollows:Principles and adviceSafety ClassesSymbols and IndexesLifespanLoads and partial coefficientThe thesis also deals with the impact that this transition into a new guideline willhave on corporations, guideline costs, education and computer software. As anexample a rough estimate on what costs this transition will create on a companywith 20 employees is also included. Calculations have been performed in order to investigate how the design valuesdiffer between the two guidelines, the Eurocodes and BKR.

Effekter av landskapets sammansättning på humlearters förekomst

The species in the genus bumblebees (Bombus) are important pollinators. In the world there are 250 bumblebee species and there are 34 species in Norway. The purpose of this study is 1) to assess changes in the species composition of bumblebees in twenty different places in Norway that have been inventoried first one time between 1939-1960 and the second time in 2012, and 2) to relate species richness and distributions to current landscape composition with the aid of orthophotos. In this study, I have used regression analyzes on the different bumblebee species that were present or absent at the inventory, using the premises of the following variables: low or high altitude, latitude, longitude and seven different types of land use (farmland, building/plots, open land/pasture, forest, wetland and open or Snow-covered ground above the tree line) to see if there was any relationship between each species and the different variables. I have not analyzed what the landscape looked like at the first inventories and therefore we cannot say whether it has changed and if that is why species number has decreased. This would be interesting to study further and to see if there is any relationship between landscape changes and bumblebee?s species decline.

Förskolebarns tankar om nederbörd

Sammanfattning Undersökningen i denna studie handlar om förskolebarns tankar om nederbörd och olika nederbördsformer. Genom kvalitativa intervjuer visas barnens tankar kring nederbörd. I undersökningen intervjuades åtta förskolebarn i åldern tre till fem år. Resultatet som tolkats visar att barns uppfattning av snö och regn är att det kommer från himlen. Majoriteten av barnen vet att regn är vatten.  De kopplar inte ihop moln med nederbörd. Barnen förstår att is är den fasta formen av vatten men inte att även snö är det.

Sociala Fastigheter : En studie om hur fastighetsdistributörer kan stärka sitt varumärke via Facebook

Aim: The aim of our study is to analyze and evaluate from a marketing perspective how estate agents can use facebook to strengthen their brand. Method: We have used an inductive study form where we?ve used a quality and a quantity data gathering method. The data has been gathered from an interview with Botkyrkabyggens marketing coordinator and from an internet survey based on a convience selection and a Snow ball selection.Theory: SWOT, Brand Equity, Word of Mouth, Customer Relationship ManagementConclusion: Facebook can create and measure "word of mouth" effects, and also create better information management and flow of information compared to traditional marketing for an estate agent. The risks of facebook is the difficulty in educating the staff about the site and the fact that facebook dominates the policies and rules which suddenly can change.

Matematik i förskolan : Hur arbetar pedagoger med matematik utomhus på förskolor med olika pedagogiska inriktningar (traditionell, i ur och skur och Reggio Emilia)?

In this essay, I have interviewed four pedagogues from three preschools whit different pedagogical purposes. The purpose was to find out how they work with mathematics outdoor. In addition to interviews, I have conducted observations at each preschool. The different preschools are one traditional, one Reggio Emilia and one ?all weather? (Friluftsfrämjandet) preschool.

Perenner i Norrbotten - Ja, varför inte? :

In this thesis, I have discussed which (herbacious) perennials that are sold most in the county of Norrbotten in the upper north of Sweden. Also discussed are the factors considering overwintering and factors that affect the chances of survival. The reason to the subject is that I m born and raised in Norrbotten and throughout the years I ve wondered why so many of the perennial flowerbeds look so similar. The purpose of the thesis is to give another approach to the composition of the garden by explaining some of the factors that controls the survival of plants. The information is gathered partly through interviews with plantshop personnel and partly by a literature study. The results of the interviews reveal that tradition and hardiness is the major reasons to the consumer s choice.

Lokalisering av skidor i lössnö : Självständigt arbete i Teknisk Fysik

This report studies the possibility of using some sort of radio sender and transmitter in order to position skis lost in powder Snow. It is concluded that a RF-solution on the 433 MHz frequency should be the most efficient. Different forms of directional antennas are examined and studies show that in theory the best suited is the so called ?Yagi-Uda antenna?. A solution based on using a Receive Signal Strength Indicator value together with the above mentioned directional antenna is developed.

Alpin permafrost i Kebnekaisefjällen : Modellering med logistisk regression och BTS-data

Denna studie är ett försök att modellera den alpina permafrostens utbredning inom Kebnekaisemassivet i norra Lappland. En karta som visar sannolikheten för permafrostens utbredning har skapats med hjälp av data från Bottom Temperature of Snow cover (BTS) - mätningar samt statistisk modellering genom logistisk regression.Fältstudien genomfördes under mars till april 2011 med totalt 56 BTS-punkter från 1073 till 1805 m.ö.h. Permafrostförekomsten bestämdes vara en funktion av höjden. För att utreda detta användes stepwise selection som är en metod för att identifiera statistiskt signifikanta variabler gentemot en beroende variabel. De andra parametrarna som testades var topografins sluttningsgradient, riktningen av den maximala lutningen och den potentiella solinstrålningen.
