Lantbruket som energiproducent : tekniska, ekonomiska och miljömässiga förutsättningar för fjärrvärmeproduktion med lokalt skogsbränsle
A third party access to district heating networks has been proposed in Sweden, to increase the competition
on the district heating market. Such third party access could create opportunities for the agricultural sector
as an energy producer. This study describes the technical, economical and environmental prerequisites for a farmer cluster to build and run a heating plant, fueled with local wood fuel.
The heating plant in the described scenario is 8 MW and will supply a village of 1000 houses, and is fueled with wood chips exclusively. Supplying a heating plant with fuel puts high demands on the logistics, since there need to be a continuous flow of fuel. In the scenario, wood residues from felling and thinning is stored in stacks in the forest, and a few times a year chipped and transported to a storage area at the heating plant.
In the study, an estimation of the profitability has been made by estimating the cost of the investment,
personnel, operating and maintenance costs and costs for the fuel and ash handling.
Virkesgripen, ett geometriskt verktyg :
The aim of this study was to investigate and describe conceptions that been used when people talks about grapples and to put together parameters that the customers sees as important when they chose a grapple from Hultdins.
Every year Hultdins manufacturer and sells about 3500 grapples around the world. With so many users its difficult to oblige everyone. To get an apprehension of what kind of grapple the operators wanted a formula with 18 questions was made. For the interviews 20 forestmachineoperators were choicest who had experience from Hultdins grapples, a lot of them also had experience from other grappleproducers and constructions.
The study showed that it is the durability the users give priority to.
Realismens utveckling från Machiavelli till Morgenthau
Political realism is a general theory within political science focusing on the principle interest defined as power. The theory?s mutual standpoint is that states are inspired by power politics meaning that military and economic power or security stands in the centre while moral and ethics are placed in the periphery. This essay?s purpose is to analyze realism which helps to understand the development and change of the perspective.
Förtolkat digitalt data till skogsägarplan
The purpose of this study is to investigate how to use remote sensing data when making a forest management plan. The main focus of the study is to compare different methods to identify forest stands of a forest property, and by manual measures and estimates try to evaluate the quality of interpreting data.
This report is based on survey questions sent to five different organizations working with remote sensing data. Only two of these where willing to participate in this investigation. The organizations where asked to analyze the same forest property and divide into compartments and make estimations of volume, basal area etc. in every stand.
En organisation i förändring. En fallstudie om Lantbrukarnas Riksförbund och riksförbundsstämman.
AbstractThe Swedish agricultural organisation, LRF, stands in front of many changes and the work with the changes in the organisation has caused some conflicts at the top. Is it like Michels say that it's a few people at the top that rules? The case with LRF shows to be something different, since the president Caroline Trapp was re-elected. The election committee proposed a new president, but the assembly had another opinion and re-elected Caroline Trapp. This shows that the opinions at the top were not the same as among the members of the organisation and the election committee couldn?t rule over them.In this essay I try to understand what kind of organisation LRF is and what made this case special.
Whispers in the forest : a field study about communication within Vi-agroforestry
The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data.
I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003)
Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.
Kjoltyg och magiska skönhetsunder: en jämförande diskursanalys av hur journalisterna på Slitz och Veckorevyn representerar kvinnan
The purpose of this study is to compare how the male journalists of the Slitz magazine and the female journalists of Veckorevyn represent the female sex. Slitz is dominated by sensual, sexy pictures of women. The texts describe the women on the basis of the journalists opinions. The women themselves do not get the same opportunities as the journalists to tell the readers who they are. Slitz magazine objectify women, they seem to be aware of it and do not hide their purpose.
"Man vill ju bara visa det bästa". : Hur unga vuxna socionomstudenter presenterar sig och påverkas av interaktionen på Facebook.
This paper focuses on how young people use and are affected by Facebook. The study embodies students from the social work program in Sweden and their view on Facebook use. Earlier research has shown that Facebook use has increased among youths. At the same time research tells us that social interaction plays an important part in shaping our identity. It is from those stands that we base this paper on, and explore our interview persons answer after the theories of Erving Goffman and the people who have studied him, such as Bernie Hogan and Zeynep Tufekci.
Det stormar i öster - en prognos över Turkiets EU-kandidatur
Turkey has taken part in regular negotiations to gain membership in the EU since 2005. At the same time is Turkey a candidate that stands out from those of earlier rounds of enlargement, and its possible membership got both supporters and critics amongst the Unions member countries. The aim of this thesis is to, trough a textual analysis, investigate the prospects and obstacles Turkeys candidature faces. The material consists of documents from a number of think tanks connected to the European Commission, as well as the Commissions own documents regarding Turkeys negotiations.A recurring picture is that Turkey is treated differently then earlier candidates, and that the Commission has a hard time keeping an unambiguous line in its negotiation frame. The material of the think tanks attributes the public opinions distrust of the member countries of EU as a hindrance, and Turkeys meddling in the conflict on Cyprus is problemized.
Röjningsbenägenheten bland privata skogsägare : en enkätundersökning bland medlemmar i SÖDRA
The intensity of cleaning declined dramatically in the early 1990?s in the Swedish forests.
Recession, an economic depressed forestry and the new law of silviculture from 1993, where
the duty of cleaning was removed have been considered as sources to the decline. This has led to a situation where huge areas of forests are untouched, which can lead to negative effects for those stands in the future.
The purpose of this thesis was to find out how the individual landowner acts and feel when it concerns cleaning activities. Has the landowner noticed Södra?s campaigns about cleaning and what sort of measure should Södra implement to increase the members? cleaning activity?
The thesis is based on a opinion poll made through a random draw among all Södra?s members.
Naturvårdsavsättningar vid avverkning på Orsa Besparingsskog
Orsa Besparingsskog has an aim to take nature considerations in relation to the harvested volume and area of the annual felling. Around 15 percent of the acreage and 10 percent of the volume should be set aside. It is important to keep close to those figures to avoid future negative effects on the long-term harvesting planning. The purpose of this study was to use laser scanning data to estimate those proportions.
The result showed that the proportion of conservation considerations in the ten selected objects in the study was significantly higher than the target of 15 percent of the acreage and 10 percent of the volume. The result showed a setting aside of 19 percent of the acreage and 17 percent of the volume.
Undersökning av självspridning av contortatallen i norra Sverige
Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions.
A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.
Hur den missbrukande modern porträtteras i samhällsvetenskaplig forskningslitteratur
In this essay, I have studied the image of the drug abusing mother and her motherhood as seen in some of the social science literature on drug abusing women. This I did with a qualitative research design and with the questions:How is the drug abusing mother and her motherhood portrayed by social scientists?What signification is her motherhood given in her life by the researchers?What approach towards the drug abusing mother in the research process, and hence in the creation of the images of her, does the scientists have?I found that there are distinct patterns and themes in the research on mothers with a drug abuse. The researchers studied the women with the goal to understand them and to give them the opportunity to speak for themselves through the researcher. The drug abusing mother is in short portrayed as a woman who cares for her children, whose motherhood is one of the most important factors in her life and who is anxious that her substance abuse should not threaten it.
EU:s klimatpolitik - förhandlingsvägen till framgång
Eleven years after broking the Kyoto-protocol, the European Union still stands in the front line, combating climate change. How come the EU, with 27 diversified states, is able to integrate its members to what is widely considered the most progressive climate policy in the world? This thesis takes a closer look at the negotiations that have shaped EU climate policy. Using negotiation-models to categorize different aspects of EU climatenegotiations, several key-findings are presented. The thesis concludes that while EU entered the Kyoto-protocol with little to lose because of external factors like previous energy-reforms in key member countries, it had plenty to win in global influence and the satisfaction of an overwhelmingly Kyoto-positive public.
Från ideell förening till vinstdrivande företag : en studie av svensk elithockey
Abstract We have in this thesis examined two elite hockey clubs in the Swedish Elite League, Brynäs IF and Linköpings HC. Our questions revolve around how they set themselves to bring in an external owner of the club. Our aim was to examine how Linköping and Brynäs stands on the issue of the external owners of the club, which is currently regulated by Riksidrottsförbundets 51/49%-rule which means that the club must control at least 51% of the club while external shareholders can take up to 49 %. Then, we compare the clubs with each other. Interviewees have been clubs club CEO:s and supporters club chairman.
