Naturhänsyn på certifierade privata skogsfastigheter : en jämförelse i praktiken mellan FSC och PEFC i Sydsverige
Nature conservation on certified small private forest owners- a comparison
between the two certification systems FSC and PEFC in southern Sweden
Today two different certification systems are used in Sweden to certify forest, FSC (Forest Stewardship Council) and PEFC (Pan European Forest Certification). During the last years certification of forests in general and different certification systems have frequently been debated. FSC is a globally widespread system and about 10 million ha out of 23 million ha Swedish forest is FSC-certified. The FSC-standard is mainly used by major forest companies and to some extent also by smaller private forest owners. PEFC is a European system and about 2 million ha Swedish forests is PEFC-certified today.
Glasbruksvillan och jakten p? den f?rsvunna dekoren
This thesis aims to propose a plausible design and construction of the lost gable
pediments of the Glassworks Villa in F?glavik, anno 1875. Through a
combination of building inspections, photo analysis and 3D modeling, the
researcher utilizes the combined results to digitally recreate the decoration that
once adorned the gothic revival villa's gable, to serve as basis for its actual
reconstruction. The study further highlights the use of modern technological
tools, such as 3D modeling software, to further enhance the understanding of
historical architectural elements. The researcher also emphasizes the challenges
and considerations involved in preserving and reconstructing historical
architectural details for future conservation endeavors..
Missuppfattningar inom genetiken: En litteraturstudie om hur missuppfattningar inom genetiken hos h?gstadie- och gymnasieelever kan motverkas
In schools, misconceptions about genetics can arise due to several factors, and the consequences of
these misunderstandings can be significant. Lack of education can play a central role in the spread of
misinformation about genetics. When teachers lack sufficient knowledge or do not have access to
up-to-date resources, they risk inadvertently conveying inaccuracies to students. Additionally, students
own preconceived notions and misinterpretations can be reinforced through interaction with their
peers, creating a vicious cycle of misinformation.
In this study, various misconceptions within genetics education have been identified and analyzed,
while different strategies to prevent these misconceptions have been examined. The study revealed that
the two most common misconceptions are the confusion between "genes" and "DNA" and the
simplified perception of genetic determinism.

The analysis insinuates the importance and status of archery in 10th century Birka..
Stjälkröksvamp (Tulostoma brumale) : stora eller små individer?
The spatial population structure of the saprotrophic basidiomycete Tulostoma brumale was investigated at a site in south eastern Sweden. Sporocarps were mapped and collected, and somatic incompatibility tests between mycelial cultures cultivated from the sporocarps were used to identify genets. Calculations of the size and numbers of genets and their distribution were performed. The spatial distribution of the tested sporocarps and the identified genets are presented graphically in a grid. The total number of identified genets within the investigated area (1210 m2) was 27 based on 48 tested sporocarps.
Vetenskapliga tidningsartiklar i klassrummet : En undersökning om lärares användning av tidningsartiklar
This paper presents why and how teachers use newspaper articles in the classroom when they educate their pupils in chemistry, biology and nature science. All the teachers have worked over 20 years and are, when interviewed, at a Swedish gymnasium in Dalarna. I also have, in a small study, interviewed some of their pupils to get their view about teachers using news paper articles during lessons.The teacher?s use of newspaper articles in the classroom can be divided in different ways. They can use the articles to illustrate up to date links to everyday life.
Enkla kemiska processer inom förskolan : En kvalitativ intervjustudie om förskollärares uppfattningar och tankar om läroplansmålet enkla kemiska processer
The aim of this study was to investigate preschool teacher?s perceptions about the curriculum goal concerning simple chemical processes. The result was based on narratives received by a qualitative study and semi-structured interviews of six preschool teachers. The results of the study showed that preschool teachers perceive that they actually are working in a relatively small scale with simple chemical processes and they do not really know what simple chemical processes are, and do not feel very familiar with the subject. Water, dough, mud, paint and baking were the most common activities that were used when working towards the curricular goal. However, it was never explained to the children that it was simple chemical processes they were working with during the activities, neither was it discussed among colleagues because of the uncertainty about the concept.
Lantbruksbaserad biogasproduktion - miljö- och energivinster
Klimatförändringar i världen är ett stort problem där alla måste hjälpa till för att stävja dess inverkan på vår livsföring. Ett problem är utsläppen av växthusgaser där djurhållningen står för en viss del. Vid djurhållning sker det en avgång av metangas både genom matsmältning och genom gödselproduktion där endast den sistnämnda är påverkbar till en rimlig kostnad. För att beräkna avgången av metan från djurhållningen i Helsingborgs stad måste man göra en inventering av djurantalet. Ett bra sätt för att utvinna metangas ur gödseln är att röta den och sedan förbränna den till koldioxid och vatten.
Arkitekturhistorisk terminologi. Antikvariskt behov av kunskapsstöd
This study you are about to read have two investigated areas concerning the need ofsources in terms of architectural historys terminology. The investigation is based on aquestionnaire study.The first aim of this study is to describe the intergrated conservations professionalqualifications in the subject. In what condition are the knowledge of them who recentlypassed the examination, what needs do the professionals have, what kind of sources duthey use in fields and are they satisfied with the amount of sources?The second aim of the study is to find out if there are any place for developing a newsource at the market? If it is, how can a new source include the informed needs?The study came up with several needs pointed out by the professionals in the field.These needs are the groundwork of a new source that the study introduce, aarchitectural glossary of terms, made of illustrations! The point is that the new idea ofglossary will meet the needs of today, rationalise the work and improve the knowledge inthe subject..
Miljöinformation från teori till praktik.
The purpose of this paper is to investigate the process of transferring information from science to "the field" of environmental protection in Sweden. I have studied four Swedish environmental organizations, Greenpeace Nordic, WWF Sweden, the Swedish Society for Nature Conservation and Friends of the Earth Sweden to see how they search/get information. I have also studied the Swedish Environmental Protection Agency and its role as sender of information, since it is the authority which is responsible for environmental information in Sweden. I have used information and communication theories as a help to analyse my results. While working on this paper I realized that my methods were not the best.
Effekten av klimatförändringar påkontrollbehovet av åkerogräs
With a changing climate, we can expect higher temperatures and more precipitation in Sweden.As the temperature increases, new weed species are expected to migrate in from more southerlylatitudes, resulting in requests for new techniques for weed control. In addition, we might see agreater number of weed species and higher biomass production due to increased concentrationof CO2 in the atmosphere.Increased understanding of the biology of specific weed species will become more importantin future weed control. This will help to control the weeds more efficiently. Higher prices onpesticides and a public demand for reduced use of pesticides make growers more inclined to usemechanical weed control on a larger scale and to a greater extent prevent weed establishmentbefore sowing. A well-planned crop rotation is the most important preventive measure, whichmight also include delayed sowing, and dark harrowing and sowing.Research takes place on many levels within the weed area and several alternative methodsare being developed.
Vetenskapsjournalistik i radio - Vad får vi veta? : En innehållsanalys av vetenskapsradions nyhetssändningar hösten 2004
AbstractPurpose/Aim: The aim of this essay is to paint a picture of science news reporting in the Swedish Public Service science programme, vetenskaps-radion. Key issues to be adressed are: What areas in science are prioritised? How much of the total broadcast time are devoted to each area? Are there any differences in reporting between weeks? How well does the swedish science radio match common interets? Are the news in the form of short ?soundbites? or are they more lengthy in-depth?Material/Method: Quantitative analysis of radio programmes. The variables used are based on the different major areas in natural sciences.Main results: This study shows that most broadcast time is devoted to news regarding biology and medicine and that the news rather are in the form of short snippets of news than more lengty in-depth stories. This is put in light of how journalistes tend to present news and that the subjects involved has to relate to peoples everyday lives.
Tillämpning av ett medium : kvalitativ pilotstudie av två generationers användning av iPad
This study aims to investigate and describe the direction of the ideological development of the Swedish gymnastics association Gymniska Förbundet. Between 1928 and 1932, this organization transformed from a purely gymnastic and cultural association into an influential platform for the production of Swedish nationalist ideology. Based on theories of National Socialism?s formation within modern society, the analysis focus on the conditions regulating Gymniska Förbundets relation to modernity. Thus the study examines the association?s ideas in relationship to the concept of modernity.
Människovana grävlingar som testdjur för grythundar. En studie om hur grävlingars beteende och fysiologi påverkas av hundars aggressivitet
In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).
