Ledtidens betydelse för privata skogsägares kundnöjdhet i samband med gallring
Today, a large proportion of wood supplied for the Swedish forest industry is bought from private forest owners while forest companies at the same time provide the forest owners with services such as logging services and transportation. Today, forest companies work extensively with keeping the time used for transport and logging short. But what does the private forest owners think about the time required for the timber deal, also called lead time, and the different parts of the timber deal.
In this thesis, the forest owners? perception of the different lead times in their contracts with Stora Enso and their communication with the purchasers is examined.
Energisystemanalys av ABB AB LV Motors
With a larger awareness of the climate changes and increasing electricity prices, energy efficiency measures in the industry have become more common. By rationalize the activity and by the same time decrease the emission of greenhouse gases the company can both save money and reduce negative environmental impact. For the Swedish industries the electricity price have traditional been relative low, which has resulted in a considerable larger usage than other European countries. By a deregulation of the European electricity market the electricity price will level off between the countries, which will cause a higher electricity price in Sweden than we are use to. To prevent that the Swedish industry don?t lose competitiveness against the other European countries, it will require energy efficiency activities in all different forms.ABB Sweden has decided to decrease their total energy usage with five percent in two years.
Lantbrukaren som energiproducent : en fallstudie i energisatsningar inom lantbruket
The intrest and development of bioenergy and energy from renewable sources in Sweden has increased rapidly over the last few years. There are a whole lot of alternatives for those who would like to venture and invest in renewable energy production.
Production of renewable energy opens up many opportunities for forestry and farming to venture a new branch of production, on basis of the primary production. Several of the new energy sources grows on farmland or in the forest. The opportunities exist in the primary products, as well as in refining and reselling, in the value chain of energy.
The starting-point is the Farmer as an energyproducer. This master thesis studies the nature of farmer-own firms, who has invested in production of renewable energy.
Kompostering av köksavfall och användning av kompost i köksträdgård i Chazuta, Peru : jordförbättring och/eller lösning på ett avfallsproblem?
All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well.
One solution to handle organic waste is to compost, which means a controlled decomposition
of organic waste under aerobic conditions at certain temperatures.
Inverkan av nederbörd, temperatur och frost på årsringens egenskaper hos boreal tall (Pinus sylvestris L.) :
The wide distribution range of our boreal pine (Pinus sylvestris L.) provides a great variation in growing conditions and climate/weather factors that influence the wood development of the trees. A great number of extensive studies have been conducted over the years in order to clarify growth trends of this and other species over more or less wide-ranging areas.
In this thesis effects of weather factors were instead compared between different forest stands from the about same geographical location. The effects of precipitation, temperature and frost on the year ring characteristics of pine were studied in the research forest of Svartberget Vindeln, in northern Sweden. The stands differed in site index and silvicultural treatment; fertile ? high stem density, fertile ? low stem density, poor ? high stem density and poor ? low stem density.
Solid återkomst.
Denna studies syfte är att ta reda på i hur stor utsträckning slöjdlärare använder sig av det utbud avmuseilektioner som finns på Göteborgs museer och institutioner. Syftet är vidare att undersöka på vilka olika sättslöjdlärare använder sig av museilektioner i sin undervisning. Slutligen vill studien ta reda på varför slöjdlärareanvänder studiebesök i sin undervisning och om de inte används, vilka skäl som anges för detta. Kvalitativasemistrukturerade samtalsintervjuer har genomförts med åtta verksamma slöjdlärare som undervisar i årskurs 7-9och arbetar inom samma stadsdel i Göteborg. Vid resultatet framkom att hälften av lärarna frekvent använtstudiebesök i sin undervisning men det är enbart en av dem som gör det regelbundet varje termin med ett uttalatsyfte.
En analys av SCA Skog AB's metod för egenuppföljning av gallringar :
A high quality is highly requested in today?s thinnings, since these are the base for continued value development of the forests. Thinning quality often means a minimization of damages on soil, stems and roots during the cutting. One way to reach a high quality is to set up goals that will be followed up after the cutting is made. Self-checking gives information of the machine drivers work and guarantees the customers a good quality of work.
En systemlösning för en framtida fjärrvärmeutbyggnad i Täby : ur Fortum Värmes perspektiv
At the moment in central Täby there are small district heating network operated by
Fortum Heat. The distribution network has an annual heat demand of about 70
GWh, which is supported by the network's two plants, Galten and Farmen.
Täby as a region is rapidly growing and there are grand plans to develop the area.
Estimated market potential for a future district heating expansion in Täby is very
high and as early as in 2007 Täby decided to invest in a large-scale expansion. In
autumn 2009 Täby did a procurement process, known as the ?Täby initiative?, to
find a partner that could implement those expansion plans. To secure a cheap basic
production the partner also need to build a power plant at Hagby recycling center.
Despite high interest during initial state of the process, only one procurement offer
were received and Täby suspended the contract in March the following year.
Pallhantering på Findus - Flöden , problematik och alternativ
The purpose of my task was to map the pallet flows at Findus and put together as well as analyze the problems. My work has also included finding out what alternatives there are to the present pallet exchange system and suggest measures to reduce the problems.The problems can be divided into poor quality and hygiene issues. The poor quality, for instance poor strength is due to arbitrary judgements and the fact that there are companies that make a system of manufacturing forged pallets of an inferior quality compared to the EUR-pallets. These pallets are marked with stamps more or less similar to the EUR-mark and taken into the exchange system. Of course there are rules how to judge a pallet but these rules are many and sometimes indistinct and there are a lot of marks to keep track of.The most dangerous part is when the pallets lack the prescribed carrying capacity.
Inhysningssystem för kalvar och ungdjur i större besättningar :
In Sweden, there has been a continuous increase in the volume of housing construction for
dairy cattle. Since 2004, the number of new, rebuilt and extended dairy cow houses undergoing preliminary inspection by the authorities has grown. The livestock farms have mostly focused on cow units instead of calf and heifer sheds; which has led to a need for information in this area. The purpose of the study was to improve advisors? knowledge about bovine building construction and function; to enable them to provide more qualified advice to conventional and organic milk producers who sustain larger herds.
GIS-modellering av habitat för vitryggig hackspett (Dendrocopos leucotos) som hjälpmedel i naturvårdsplanering på landskapsnivå :
The white-backed woodpecker is a forest bird being critically endangered in Sweden. The species is dependent on older forests rich in deciduous trees and dead wood. The main problem for the survival of this species is present shortage of habitat. Conservation work on this umbrella species is at present focused on finding remaining or emerging habitat networks. Large areas are scrutinized in search for suitable habitats to be protected or managed for the species sake.

Samerna och statsmakten : Vardagligt motstånd och kulturell hybriditet i Torne lappmark under perioden 1639-1732
This thesis examines the everyday resistance, and its interaction with cultural hybridity, of the Saami population in the administrative unit of Torne lappmark during the period 1639?1732. To do this, the thesis uses theoretical concept of everday resistance as it has been described by JamesC. Scott and the theories of cultural hybridity as they have been described by Peter Burke. Primary source material used in this thesis consists of the court records from Torne lappmark, specifically from the courts at Jukkasjärvi and Enontekis.The results of this thesis present a picture of the everyday resistance in early modern Torne lappmark.
Planering av lägerområden : exemplet Sjöröd
This is a final thesis on the landscape architecture
program at the Swedish University of Agricultural
Sciences. It is the end of five years of studies and
comprises 30 ECTS.
This thesis is about the camp area Sjöröd, located
by Gyllebosjön (the Gyllebo Lake) on Österlen in
Skåne, southern Sweden. The thesis results in plan
for how the area could be used in the future. It also
raises the questions; what scouting of today is, how it
is to be developed for the future, what a camp is and
which aims the scout movement has set up for itself
and its activities. The thesis also treats what is typical
for Skåne, for Österlen and for the area around
Sjöröd as a starting point.
Forest and water governance in Sweden
Water related problems are highlighted as a challenge to sustainable development and the topic of forests and water is gaining increased attention worldwide. Governing forest and water is a complex issue, as the interactions are affected by policies and actors from multiple levels and sectors. In Sweden, forests cover much of the land and forestry is an important land-use, inevitably impacting the water in the landscape. This study aims to understand and explain the existing governance framework around forestry and water in Sweden. Based on the Policy Arrangement Approach, the study?s research questions focused on the actors involved, the formal and informal rules, the resources and power structures and the discourses related to forestry and water in Sweden.
