Deadwood in piles or distributed : does it make any difference to saproxylic beetles?
Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofpiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent pile positions (up and low) was studied and compared to distributed deadwood samplesaround each pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, pile volume and decay stage were assessed to define any effect.
?Båtnitar? : Analys och konservering av järnnitar från Birkas garnison
The purpose of this paper is to analyse and discuss clinch-nails found at an excavation at terrace II in the Garrison of Birka, on the island of Björkö in Sweden. This type of clinch-nails is common in Viking age Sweden and is usually interpreted as coming from boats. The study will try to show that these types of nails could have been used in several kinds of wooden constructions. It will also show how the nails were made and what kinds of tools were used by the Viking smiths. The study has shown that this type of nails were used in several different types of wooden constructions such as boats, sleds, cart bodies, coffins, Birka's ramparts and buildings.
Utvärdering av Hultdins prototyp för portabel bro (drivningsbro) :
Stronger demand has been put on forestry to show environmental considerations during harvesting. This is especially for crossings of brooks with sensitive elements and great care should be observed when they are to be crossed during harvesting by logging machines. For that reason Hultdins has constructed a portable bridge that can be used for those occasions. The bridge has been developed in accordance with wishes from SCA forest, since they have a great deal of brooks in their forests and in private forests from where they buy part of their wood supply.
The aim for this report is to investigate if this portable bridge can be of interest for the forestry market. The research has been made at SCA skog in Medelpad and Norrskog in Medelpad.

Det förändrade underlivet : En undersökning om kosmetisk intimkirurgi borde omfattas av lagen mot könsstympning
The swedish law against female genital mutilation (FGM) prohibits procedures that removes parts of the female genitalia and thereby makes permanent changes in the body. The problem with the wording of the law is that it may also apply to the western phenomenon cosmetic genital surgery. This paper therefore examines if cosmetic genital surgery should be covered by the swedish law against FGM, by making a critical comparing analysis. The paper begins with comparing FGM with cosmetic genital surgery to prove that there are more similarities than differences between the procedures. By using the theoretical perspectives universalism and postcolonialism, the paper then examines why, particularly in the West, there is a different approach to FGM than to cosmetic genital surgery, regardless of the similarities of the procedures.
Det svenska områdesskyddet : Ett samspel mellan diskurs och institutioner
Sweden has had laws protecting nature for about a hundred years. In this paper the views of nature and the values that serve as a rationale for protective measures are analyzed as results of a social process characterized by the dialectic relationship between institutions and discourse. Critical discourse analysis (CDA) is used to study this relationship and the discursive practices used by institutions, which reproduce or reshape views of nature that define the relationship between society and nature. Institutional design contributes to shaping discourse in the field of nature protection, while being originally shaped by discourse. In Sweden, the national park is an institution that reproduces a view of nature as the wild and untamed opposite of society, and the natural reserves reproduce a view of nature as holder of a multi-faceted set of values intertwined with society.
Förvildade husdjur : möjligheter och hot
Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.
C?RONIS BIVAXFERNISSA En unders?kning av inneh?ll, l?slighet och ?ldringsegenskaper
The aim of this study is to provide a comprehensive overview of C?ronis beeswax varnish by Lefranc &
Bourgeois; its contents, aging properties, solubility, and possible removal methods, with G?teborgs
Konstmuseum?s ?Gothenburg Museum of Art? collection as the stud??s material? The purpose of the
study is to provide a basis for decision-making regarding the treatment of works treated with C?ronis
wax varnish. The study is based on contemporary conservation theory and interpretation-based
decision-making and utilizes FTIR, microscopy, and solubility tests to examine the properties of the
varnish. The study shows that C?ronis does not appear to be harmful to the treated works and has
retained its solubility properties and transparency over time.
Tillämpning av naturvårdsavtal :
Nature conservation agreement (NCA) is a way to voluntarily protect and manage nature for limited time-periods. The agreement is settled between the government and a landowner. All public authorities can represent the government but it is only the Swedish Forest Administration who does that regularly (because it is the only authority with economic resources for that purpose). Therefore, NCAs are almost only used to protect forested nature.
The government agencies have experienced NCAs for about ten years and it is now time to examine how they are applied in the forests. This study is based on a computerized questionnaire to the persons responsible for the LEKO-projekt.
Avsättningar i pappersmaskiner : Utbildning och förslag till processförbättringar
Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.
C# - Framtidens språk???
This paper is about the new programming language from Microsoft, C# (See Sharp)
and the
.NET Framework. They are still in beta-version, but will be released on the
market in
February 2002. This paper presents C#, not in detail but the characteristics
that distinguish the
language. A comparison is done with C++ and Java, since C# is most resembling
to these
languages. Both C# and Java have been developed from the mother- language C++.
Flerskiktat papper : en sammanställning av historia, teknik och forskningsresultat
Until the beginning of the 1900:th century the paper making process was handicraft. The paper machines that have been developed since then are as impressing in size as fascinating when it comes to the technique. The process has always been improved to give a better paper for lower costs, with as short manufacture time as possible. Stratified forming has been a reality since 1830. From the beginning it was applied to board and paperboard.
"Du ska se oss på idrotten" : En studie i hur flickor och pojkar tar plats i idrotts- och svenskundervisning
In this paper an upper level compulsory school is examined from a gender perspective. The purpose of the paper is to analyse how girls and boys acquire space in the classroom (during a Swedish lesson) and in the sports hall (during a lesson in physical education). To fullfil the purpose of this paper a seventh grade class was observed during a lesson in Swedish as well as in sports. In addition to this on pupil was interviewed. In this paper the results are compared to and measured against results from earlier research in the field. Used as a theoretical basis are Simone de Beauvoir?s theories on gender.The results attained indicate that girls and boys claims space in different ways during time in the classroom as well as in the sports hall.
Återförvilda Sverige?: En studie av rewilding som strategi för att bevara kulturlandskapet och gynna biologisk mångfald
Through millennia, humans have shaped the European landscapes. Agriculture, hunting andforestry have influenced virtually every ecosystem on the continent and formed what we todaythink of as the cultural landscape; a mosaic pattern of cropland, fields, pasture and forests. Thepast two centuries, globalization, industrialization and urbanization have come to pose a threatto the existence of these landscapes. European farmlands are now being abandoned at analarming rate, and the associated loss of landscape preservation, biodiversity and ecosystemservices is a concern to the scientific community and public alike.This thesis studies if the implementation of the relatively new conservation strategy rewilding(recreating self-sustaining ecosystems and reintroducing keystone species) can be a part of thesolution to preserve cultural landscapes and biodiversity in Sweden. Through interviewssupplemented with studies of published works, expertise from different fields has beencompiled to provide an overall picture of the capacity of rewildings as conservation method.
Arbeta inteam(t) : En studie om team och teamarbete
AbstractThis is the paper you should read if you want to know more about working in team. Teamwork is a way of working and it increases more and more among societies and companies today, but it is not quite clear what the diffrences is from working in groups. We have in this paper tried to clear out the differences between groups and team, and we have also tried to give an oversight of how to work in team in organizations. Cultures of organizations, leadership and power and also development of qualifications are big parts of an organization´s daily work, and we have explained these concepts from a teamperspective.We have, in this paper, done interviews with people that have been in contact with the central consepts that we use. And then we have analyzed their answers with help from litterature, which we have closely studied, thereafter we have presented our results.
