Energikartläggning hos RostiGP i Gislaved

In today?s modern age, energy consumption has become a major issue, both from an environmental viewpoint and cost perspective. Because of a rapid technologic change and increased costs of production of electricity, the demand to develop effective methods for energy efficiency industries have grown.The electricity-intensive industries, such as plastic industry, the demand to reduce energy consumption has grown significantly over the past 10 years, which have led to the development of different methods to determine and locate energy-consuming parts in the industry. This also means being able to prioritize and organize activities in the industry.In this study the measurements of voltage, current, power and PF performance on injection molding machines (K-TEC 275 form Ferromatik Milacron in Germany) with a focus to locate, within a machine, various measures that could improve energy use in the plastics industry, in this case RostiGP in Gislaved. These measurements have been carried out with the help of a power quality clamp meter to carry out time logs of the machines for some time during normal word rate.

Flerträdshantering i slutavverkning

Flerträdshantering har sedan länge främst förekommit i gallringar och vid skörd av biobränslesortiment. På senare år har svenska och kanadensiska forskare även gjort tidsstudier på tekniken i slutavverkningar där resultaten visar på en ökning av produktiviteten. Inom Holmen Skog har tekniken använts i slutavverkningar under ett par års tid men kunskap om vilken typ av skog den bör användas i och potentialen är okänd. Syftet med denna studie var att kvantifiera potentialen för flerträdshantering i slutavverkning inom Holmen Skog och beskriva de skogliga förutsättningarna. Det gjordes även en skattning av produktivitetsökningen och en maskinkostnadskalkyl för flerträdshanteringens effekter på skördarens drivningskostnad. Studien utfördes enligt följande: Stamnotor extraherades från slutavverkade trakter där flerträdshantering användes.

Hur skall skogen skötas? ? en analys av skogsfastigheten Fagerdal 2:10 i Jämtland

The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined. A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.

Översättningsprocessen vid översättning av fasta fraser hos professionella och icke-professionella översättare : En empirisk undersökning

Processen vid översättning av fasta fraser har hittills inte skänkts mycket uppmärksamhet inom den processorienterade översättningsvetenskapen. Denna deskriptiva studie försöker bidra med empiriskt material angående vissa aspekter av översättningsprocessen vid översättning av svenska fasta fraser till tyska. I undersökningen med sex tvåspråkiga försökspersoner, varav tre yrkesverksamma översättare och tre personer utan översättningserfarenhet, användes en kombination av en produktbaserad metod och processinriktade metoder som skrivloggning med Translog och retrospektion för att finna ut vilka översättningsstrategier vid översättningen av idiom och andra fasta fraser som väljs, på vilka vägar försökspersonerna kommer fram till sina slutliga val och om det kan skönjas några skillnader mellan yrkesöversättarna och lekmännen. Resultaten visar bl.a. att det var vanligast att översätta med parafrasering samt med en målspråksfras med liknande betydelse och liknande eller olik form, och att försökspersonerna kom fram till sina slutliga val med enbart få provisoriska skriftliga motsvarigheter, men genom en del längre överväganden kring betydelse och stil.

Markskador vid GROT-uttag : en enkätstudie hos skogstjänstemän

Forestry is increasing on an industrial scale where collection of logging residues takes a greater part. This has resulted in more machinery and heavy machinery driving in the clear felled area, this increases the risk of soil damage that will occur in the form of soil compacting and rutting in the clearings. This affecting on the nature in a negative way and especially in rivers and lakes that are affected by siltation and acidification leading to increased levels of heavy metals and methyl mercury. The purpose of this study was to investigate why there is damage to the ground when working with the slash in forest management from the forest officer point of view. A self-designed questionnaire was used and 45 questionnaires were sent out to various companies all over Sweden.

Urskogen med de stämpelbleckade gammeltallarna : en skogshistorisk tolkning av Brännlidens naturreservat

People have used forest resources in northern Sweden for different purposes. Before the 20th century the forest was used for many different reasons, but during the past 200 years it has become an industrial raw material. The presence of people in the forest has left different kinds of traces in the forests. One example is culturally modified trees (CMT´s). The aim of this study was to study and document how people have used the forest resources during the last centuries in Brännlidens nature reserve, and what kind of traces this land use has left.

Kommuninvånarnas syn på Sala kommuns skogar och skogsbruk

The municipal forests of Sala cover an area of 6 000 hectares, starting in the vicinity of the city and reaching north. At the same time as residents make abundant use of the areas closest to the community for outdoor activities and recreational purposes, the forest is of great economic value and also worth protecting for environmental reasons. These conditions make forestry in periurban woods more complex than conventional forestry, why a good understanding of the needs and demands on the forest and silviculture program is required. The purpose of this study is to depict the usage of the forests owned by the municipality of Sala, to set forth the common view of the silviculture program implemented by the municipality and to chart the expectations the community has on the forests and forestry of the future in the municipality of Sala. The survey part of this paper consists of the interviews of thirteen individuals representing nine interest groups. As expected the views of these individuals varied widely but some results were expressed by more or less all of them.

Ett gammalt kulturlandskap i Vindelfjällen : skogshistoria och markutnyttjande i Vuornavagge under 300 år

Humans have inhabited mountainous areas in northern Sweden since the end of the last glacial period, ca 8000 B.P., and their presence has marked the landscape in various ways. Older traces include the remains of hearths and dwelling sites, but there are also remains, such as culturally modified trees (CMT's), resulting from more recent activities in forested areas. This study aimed to document how people, both indigenous Sami's and Swedish settlers, have used an area northwest of Ammarnäs in Västerbotten, during the last 300 years, and what traces their activities have left in the area. I used historical records as well as an inventory of CMT's in the area to address this aim. Historical records of Sami activity are meagre, but it is clear that the people of the Ran and Gran Sami villages utilized the area long before 1500 A.D.

Restoring biodiversity in degraded secondary rain forest in Sabah, Malaysia : natural regeneration of trees after restoration treatments

Many tropical rain forests has been lost or degraded as a result of human activities and environmental factors. Since the level of biodiversity is high in the tropics, maintaining these areas is of great importance. Forests like these are often assumed to benefit from forest restoration and rehabilitation. The INIKEA project area in Eastern Sabah, Malaysian Borneo, aims to improve biodiversity and/or species richness in the degraded forest through enrichment planting with indigenous species. The objective of this thesis was to evaluate how different treatments (liberation, gap-cluster planting and line planting) affect the biodiversity of natural regeneration in different forest types in the Rain forest Restoration Experiment, located in the INIKEA project area.

Metod för att bestämma drifttid

The usage time is an important part of the specification for products powered bybatteries. The usage time is affected by a number of different elements; technical,environmental and how the product is being used. The method to determine theusage time is intended to define how measurements and calculations are to berealized along with influencing factors to keep in mind. With support from thismethod the intention is to gain control on how well the established usage time canbe expected to cohere with the real value and what affects the value.The study is done specifically for hearing protectors with battery powered built inelectronically functions. The functions can be level dependent function forambient hearing, 2-way radio communication, Bluetooth or FM-radio.The first chapter of the report describes the literature study performed in theproject.

Naturvärden i en värmländsk bruksskog : en skogshistorisk studie av Åbengtshöjden/Bogranghöjden

In this study I have analysed the history of a forest belonging to Saxåhyttan in Värmland. The study area is 448 hectares and has been used by iron industry since the 16th century. A forest that has been used by man during at least 400 years should have few ecological values. This inventory however shows the opposite. The aim of the study is to interpret the history of the forest in the area, i. e.

Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

Samiskt skogsutnyttjande, dimensionsavverkningar och naturvärden : skogshistorisk analys i block 5, Pakko kronopark i Norrbotten

In order to understand the human impact on today?s remaining ?virgin? forest and to develop sensible management strategies for future reserves, it is necessary to know how these forests have developed. This knowledge can be gained by using forest history analysis. here are large areas of forests still untouched by modern forestry in the mountainous region in the county of Norrbotten. These forests are highly interesting study objects from an ecological and historical point of view.

Daily rests of wild boar Sus scrofa sows in southern Sweden

For a few decades, the wild boars are established over large areas in southern and centralSweden. Where they cause problems in terms of damage to crops in the agriculturelandscape, where rooting, browsing and trampling, but also damage to the crop when wildboars chosen daily rest in the cultivated fields. Along with the growing number of wildboars the rate of car accident with wild boars has also increased.Here I examined the daily rests of wild boar (Sus scrofa) sows in southern Sweden, todetermine the factors which the wild boars sows choose for daily rest. By determining whatfactors are important in this selection of daily rests, we may be able to make managementmeasures to reduce the damage wild boars make in the agriculture landscape by attractingthem to places where they do less economic damage and accidents on roads.In this study I have examined 123 daily rest positions from 14 different individual wildboar sows fitted with GPS collared in Southern Sweden, Skåne County in Christinehof,Högestad Kronovalls estate. Data was collared over the years 2004-2006 during the periodfrom June 1 to September 30.

Styrning av kundanpassade timmerflöden : inverkan av traktbankens storlek och utbytesprognosens tillförlitlighet

För att kunna styra våra avverkningsoperationer i skogen är vi beroende av någon form av beslutsunderlag. En form beslutsunderlag är prognoser på utfall vid avverkning som ger en skattning av längd-, diameter- och kvalitetsfördelning i ett avverkningsobjekt Prognoser kan vara till hjälp vid styrning av timmerflöden från skog till såg. Denna uppsats har till syfte att besvara frågorna: Vilken prognosnoggrannhet kan erhållas med hjälp av SkogForsks apteringssimulator Aptan i praktisk drift? Hur påverkas möjligheterna att styra timmerflödet mot vad marknaden efterfrågar av hur stor traktbanken är? Arbetet har bestått i att jämföra stocknotor från prognos, skördare, inmätning och postning samt simuleringar av hur olika traktbanksstorlekar kan uppfylla skiftande efterfrågan. Skiftande efterfrågan har simulerats genom att skapa önskestocknotor ( detaljerad efterfrågan) för fyra olika efterfrågescenarier.
