Metodutveckling för planering och genomförande av dikesrensning med moderna metoder

?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes. In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests. So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland. We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning. A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests. This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.

Kulturmiljöhänsyn inom skogsbruket : En studie om fornlämningar och gränsmärken

Bakgrund      Skogsmaskiner har under många år förstört både fornlämningar och gränsmärken. Idén till databasen/tjänsten uppkom av egna erfarenheter vid en förrättning, där flertalet gränsmärken hade blivit överkörda av skogsmaskiner. Syfte              Examensarbetets syfte är att lyfta fram en ny idé för att minska skadorna på fornlämningar och gränsmärken som skogsmaskiner orsakar, samt hur lägesnoggrannheten påverkar den nya tjänstens ändamål.Metod           Examensarbetet består av en litteraturstudie med syfte att besvara och ge en bakgrund till problemställningen. För att undersöka hur vanligt det är att lantmätare/mätingenjörer stöter på att gränsmärken blivit skadade av skogsmaskiner genomfördes en enkätundersökning. För en djupare inblick av lägesnoggrannheten på utrustningen i skogsmaskiner och vilken kvalitet på koordinaterna som krävs för en mer ändamålsenligt tjänst gjordes en intervjustudie.Slutsats         De uppgifter som finns tillängliga idag ska vara användbara när det gäller fornlämningar, för en ändamålsenlig tjänst som ska fungera ute i skogen där lägesnoggrannheten inte alltid är den bästa.

Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper

At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.

Dubbskador på Alvestakubb

Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.

Köpares syn vid förvärv av lantbruksfastighet i Dalarnas och Gävleborgs län

Today's real estate buyers value the purchase different today compared to a decade back. Previously it was the return value that ruled the market. This has created problems when the broker must allocate the purchase price of the property's various elements, because non-monetary values such as forest for leisure, recreation, and the feeling of owing has increased in recent years and an increasingly important part in the valuation process. The assessed value can be a guide, but is perceived today to be stereotyped to put a fair value at the individual item. The purpose of this study was to provide the real estate agent decision support and a guide to the likely value of accounting for the purchase price. The report is written on behalf of LRF Konsult. The result is based on a questionnaire survey which was conducted in June 2014 among all those who had bought a farming property in Dalarna and Gävleborg province mediated by LRF Konsult in 2013. The report was made with a split to see if the valuation and motives differ between new and previous owners. It was possible to see a big difference in the reason for the purchase, where a large share of new owner bought the land for capital investment, in contrast to previous owners whose biggest group bought for an active use. At several points it was possible to identify a higher non-monetary value of the new owner from the previous landowner.

Hemlöshetsdiskurser : Bilder av hemlöshet och hemlösa i Dagens Nyheter, Aftonbladet och Socialstyrelsen åren 2000 och 2012 ? en diskursanalys

Homelessness and homeless people is something that is described and explained in different ways over time. Since the 1950s, two discourses about homelessness and its causes has been competing with each other. One discourse hold the meaning that homelessness is caused by housing shortage and the other focus on individual shortcomings that make homeless to unsuitable tenants. In the media, homelessness and homeless often is associated with crime, addiction and mental illness, this reinforce the public perception of homeless people as deviants, which separates the homeless from society even more. The purpose of this study is to examine whether media representations of homeless and homelessness in an evening paper and a morning paper, has changed in the 2000s, and if these representations are consistent with those found in the reports of homelessness from The National Board of Wealth and Welfare. In order to achieve the purpose of the study and answer our research questions, the authors have used a discourse analytical approach using some key analytical tools from both critical discourse analysis and discourse theory in the analysis of the empirical material.

Elementkoncentrationer i gran utmed en markfuktighetsgradient :

One key factor in silviculture today is sustainability. In order to achieve sustainability it may be important to restore lost nutrients to the forest after clearcutting. In order to calculate the removal, you need to know how much of different elements you will find in different tree compartments. The aim of this study was to investigate if the concentration of elements in different tree compartments of spruce (Picea abies (L.) Karst) were related to the moisture conditions of the site. Five plots at Risfallet (60º 21´ N, 16º 13´ E), was placed along a moisture gradient in a 40- year spruce stand.

SÖDRAs Gröna Skogsbruksplaner : en uppföljning relaterad till SÖDRAs miljömål, FCS's kriterier och svensk skogspolitik

SÖDRA beslutade 1995 att starta ett projekt för att förse föreningens medlemmar med naturvårdsanpassade skogsbruksplaner. Projekt "Gröna skogsbruksplaner" har som mål att fram till år 2002 täcka halva medlemsarealen med gröna planer, och har för att nå detta givits en budget på 50 miljoner kronor. Konceptet med grön plan är ursprungligen skapat av skogsvårdsorganisationen, men SÖDRA är först med att producera gröna planer i stor skala. De gröna planerna skall enligt projektets syfte "ge SÖDRAs medlemmar ett verkningsfullt redskap for virkesproduktion med hänsyn till de miljömål som finns formulerade i SÖDRAs miljöpolicy". Detta är ett led i det miljöengagemang som på senare år ökat i Sverige.

Kapsprickor och avverkningsaggregat

This study was made for the Swedish forest company Sveaskog because the sawmills they delivered timber to had noticed a high frequency of bucking splits in their products. Coworker Jim Edström at Sveaskog also wanted to know if there was a big difference between different felling heads. The purpose with this study has been to find out the amount of bucking splits and if there is any felling head brand that did a bigger damage that the others. The study was made in two steps, where the first part was a literary review to find out results and conclusions in earlier studies. The best measuring method to check bucking splits was the known ?trissmetoden?.

Etanol : ett hållbart tankande eller ett kortsiktig tänkande?

Ethanol fuel is a biofuel, which been widely reported in the public debate and on the fuel market the last years. Ethanol is sold as both E85 and as a five percent admixture of all petrol sold in Sweden. Research studies on ethanol fuel often focus on environmental issues surrounding the production and utilization of ethanol as a fuel, and omits the private and business aspects of the subject. The purpose of this study is to illustrate the economics of ethanol as a fuel. How the Swedish market for ethanol is and how it evolved over time and what the future prospects are.

Jämförelse mellan renskötsel och betesbaserad fårskötsel

This essay describes and compares the extensive reindeer management to the more intensive, but grazing based, sheep management system in Sweden. Differences and similarities between the two production systems will be investigated by elucidating the economy, land use and possibilities to influence production and economy through breeding, feeding and product development. The reindeer management area covers the northern part of Sweden whilst the sheep management is dispersed over the country. Both reindeer and sheep are ruminants and have relatively high demands on the quality and digestibility of the feed however reindeers graze on mountain-and forest lands whilst sheep often graze inaccessible areas or cultivated grasslands. Selection intensity is generally lower in the reindeer management compared to the intensity in sheep breeding.

Vägen till ett självständigt liv? : en studie om Rekryteringsgruppens betydelse för ryggmärgsskadades rehabilitering

Aim?Rekryteringsgruppen? (RG) is an organisation that through co-operating with the National Health service aims at optimizing the ability for physically disabled persons to rehabilitate. RG is a non-profit organisation ?using physical and mental exercise for disabled people, mainly neurologically disabled persons.? One of the goals that RG wants to achieve is ?that the target group will be able to live such an active and independent life as possible?. As no previous studies have been done in order to review the adaptation of RG:s work and its effects on the disabled, the purpose of this paper is to examine spinal cord injured individuals perception of independence concerning situation of life, ability to function and physical activity.MethodData have been collected by using three questionnaires.

Strömningen i och över en skog : utvärdering av en 'mixing-layer' hypotes

A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations that give the wind profile. The theory has been used to calculate wind profiles for sixdifferent atmospheric stabilities.

Uppsats f?r avl?ggande av filosofie kandidatexamen med huvudomr?det kulturv?rd med inriktning mot bebyggelseantikvarisk verksamhet 2024, 180 hp Grundniv? 2024:03

Local cultural environment planning in Sweden often comes to rely on municipal heritage plans. These plans are meant to facilitate management of local cultural values, work as a tool for local planning and increase awareness of cultural environments for the public. In the last decades public participation in planning has become more and more of the ideal strategy, challenging the idea of cultural environment planning as an expert-led field. The idea of the field as one that implicates public participation as a strategy has been fortified in Sweden through national goals, government bills and conventions. Nevertheless the implementation of public participation in municipal heritage plans remains quite uncharted. The aim of this study is to explore public participation in regards to how municipal heritage plans are developed and the perception of public participation in cultural environment planning amongst professionals, comparing bigger and smaller municipalities.

Förbättrad vakuumtätning mot kabeln under plastextruderingsprocessen

This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.
