Evighetsträd

FSC (Forest Stewardship Council) is the major form of certification system in Swedish forestry today and its more than 11 million hectares are covering almost half of the total productive forest area in the country. Its regulations prescribe that at least 10 wind firm trees should be left behind after every clear cutting operation. This study have taken place on 30 recently clearcut objects in Bergslagen, Sweden, were an inventory of the standing stock have been made. The research shows that, with 90 % security, the retained trees together contain 9-13 m3sk per hectare. Pine is the dominant tree and it covers more than half the numbers of retained trees and its volume cover 65 % of the retained trees total volume. Spruce is on second place with 30 % of the retained trees, but only 21 % of the standing stock.

EN REN KONFLIKT, OM REN, VIND OCH MALM En normativ studie om samernas r?tt till mark under den gr?na omst?llningen

This study aims to unravel if it should be accepted to use natural resources in the Sami reindeer grazing area for the green transition. Mines, wind parks, and other infrastructure in the reindeer grazing area create problems for the reindeers which makes it difficult for the Sami to proceed with this traditional practice. While the Sami people have right to practice these customs the minerals and land which in it lies could be crucial to successfully go through the green transition in Sweden and the European Union as well. To answer the question: Should it be acceptable to use natural resources in the Sami reindeer grazing area to accomplish the green transition? a reflective equilibrium will be applied to the principles of egalitarianism and collective rights.

Vattenjärnhaltens betydelse för mjölkkors hälsa och produktion :

Drinking water from drilled wells has a high content of iron and other minerals in many places in Sweden. Questions about the association between the quality of drinking water and the health of dairy cows are regulary asked both by advisers and dairy farmers. There are so far not many studies published about the relevance for high iron content in water and dairy cow health and production. Therefore, the aim of this study was to investigate if there is a connection between the iron content in water and the health of dairy cows. Initially a literature study was made about iron and it´s function in ruminants.

Vad ska vi dricka idag?

Background The usage of Nutrition supplement in the elderly care is commonly occurring and plays an important role in the intake of nutrition for the elderly. The usage of nutrition supplement is to reduce malnutrition within elderly care. For the elderly it is crucial to keep a healthy diet and to never lose weight. The loss of weight can be very dangerous it could even be fatal for the aged and should therefore be avoided. To have a diet that is rich in energy such as enriched meals prevents the elderly from receiving a shortage of calories since the diet is rich in fat, protein and thus also rich in energy.

Diagnostiska metoder för växtvirus i nematodvektorer :

ABSTRACT Tobacco Rattle Virus (TRV) is a soilborne plant virus. It is an important pathogen in potatoes where it causes spraing disease. This disease can lead to significant economical loss for the farmer, so it is imperative to get the proper diagnose before planting. TRV is spread naturally by free-living nematodes (Trichodorus and Paratrichodorus). Transference of TRV to a plant occurs when the virus-carrying nematodes feed on plant roots. The relationship between virus, nematodes and plants is complicated, and has to these days not been fully characterized. The diagnostic methods available today do not work sufficiently.

Examination of mycorrhizal associations of Allanblackia stuhlmannii : a tree under current domestication

Allanblackia is a tree genus native to humid forests in West, Central and East Africa. Its fruits contain large seeds from which edible high-quality fat can be extracted. In order to create a sustainable supply chain of Allanblackia seeds, a domestication program has been initiated with the purpose to enable smallholder farmers to grow the tree as an agroforestry component and cash crop. More knowledge is required to understand the tree?s biology and possible symbioses involving soil microorganisms with plant growth enhancing poten-tial.

Generation of mutated expression plasmid KRT1 and comparison of HaCaT cells transfected with expression plasmid KRT1 or KRT10 concerning keratin aggregates

Introduction The genetic skin disease epidermolytic ichtyosis is caused by mutations in either keratin gene 1 or 10 and leads to blisters and hyperkeratosis of the epidermis. At cellular level the disease is seen as aggregates in the keratin filaments. Since medicines are hard to investigate and produce mainly due to lack of reproducible model systems, there is no good treatment available for this disease today. In this article we describe how an in vitro model consisting of cells from a stable cell line transfected with expression plasmids to mimic patient cells, may be a possible alternative for screening compounds for therapies. The first step was to generate an expression plasmid required to complete the in vitro model.

Relationen mellan den fackliga organisationen och företagsledningen Vid en organisationsförändring på Länsförsäkringar Bergslagen

Syftet med studien är dels att belysa och synliggöra på vilket sätt som ett adopterat barn blir bemött av lärare vid inskolning samt att få en föreställning om hur vårdnadshavarna uppfattar inskolningen.Studien vilar på Bowlbys anknytningsteori och utgår från följande frågor:? På vilket sätt beskriver lärarna en inskolning av adopterade barn?? Hur uppfattar vårdnadshavarna förskolans inskolning?Vi intervjuade två vårdnadshavarpar till adopterade barn och två lärare som har inskolat adopterade barn på förskolan. Barnen som är med i studien var tre respektive fyra år när de började på förskolan. De hade då varit ungefär ett år hos sina vårdnadshavare här i Sverige.Genom att intervjua lärare och vårdnadshavare till adopterade barn har vi fått fram fakta om hur inskolningar kan vara. När vi sen har analyserat svaren har vi insett att kunskap och förberdelser är viktiga inslag för en bra inskolning.

Är skolbiblioteket viktigt? En undersökning bland elever, lärare, skolbibliotekarie och skolledning om deras attityder, behov och förbättringsförslag på en utvald 7-9 skola i Bergslagen.

The purpose of this essay is to illustrate the importance of the school library in a selected junior high school. My investigation is based on both theoretical and empirical studies. The aim of the theoretical part is to create a platform and refer to thoughts, roles and laws concerning the activity of the school library. The empirical investigation consists of two parts: questionnaires among students and teachers, plus interviews with students, teachers, headmaster, school librarian and the management of education. Everybody shows a positive attitude towards the school library and considers it important for the students exams.

Kampen om ett föränderligt Arktis : En jämförande studie av Rysslands och Kanadas agerande i Arktis och Arktiska rådet.

The Arctic region is rich in natural resources such as oil, gas, minerals and fish. Climate change causes the Arctic ice melt, making resource extraction possible as well as opening up new transport routes through the Northwest Passage and the Northeast Passage. This has led to competition and cross-border strife among the Arctic States. The two largest states in the Arctic are Russia and Canada, which are also members of the Arctic Council. Russia and Canada are at the moment involved in several disputes regarding the Arctic territory where the ownership of the North Pole is one example.

Visbys färger : exteriör färgsättning av bostadshus i Visby innerstad 1860?1930

The main aim of this research is to survey the general colour scheme for private dwellings inVisby, built 1860?1930. During this period the visual appearance of the town of Visby changedsubstantially, since the increased local production of lime led to the plastering of many woodenbuildings. Which colour schemes were chosen for the different building types of the historic centreof Visby, and which colours came to dominate the time period? The methods used for answeringthese questions have partly been field studies on site and sampling of selected buildings, andpartly critical reading and observation of iconographic material (paintings, drawings, aquarelles,postcards and photographs).

Flockning och förtjockning i High-Rate-förtjockare ? en jämförelse med konventionell förtjockarteknik och lamellsedimentering.

In the process laboratory of Metso minerals (Sala) AB, continuous tests have been made with a laboratory unit High-Rate thickener. The tests are made in order to compare three methods of thickening techniques of suspended solids. The three techniques are High-Rate thickening, conventional thickening and lamella thickening. The High-Rate and the conventional trials are based on a continuous method, while the lamella thickener is based on batch trials. Because the lamella thickener is based on batch trials and there were some optimization problems with the adding point of the flocculant at the continuous trials, it was not feasible to compare the lamella thickener with the other two thickener types.

Garvaregården 6:8 : en ny gestaltning med historisk anknytning

Garvaregården är en bergsmansgård byggd år 1810 och det finns en önskan om att restaurera trädgården i historiskt ursprunglig stil. Det finns inget dokumenterat om trädgården som till största delen är belägen om husets östra sida. Syrénhäck, äppelträd och vinbärsbuskar är några utav de växter som finns där. Med hjälp av ett antal analyspunkter, som rekommenderats i utbildningen när man kommer till en projektplats, har jag gjort en inventeringsplan efter utmätning och växtlista efter artbestämning. Under arbetets gång har jag därför iakttagit vad som sker på platsen. T.ex.

Fredriksberg kommer aldrig att bli ett Världsarv : en studie av vardagslandskapet

Denna uppsats behandlar den Europeiska Landskapskonventionen och begreppet vardagslandskap. I en fallstudie av bruksorten Fredriksberg i Bergslagen berättas en historia om vad som händer med en bruksort och dess vardagslandskap när ortens största näringsverksamhet läggs ner. I uppsatsen problematiseras frågor så som; hur ett vardagslandskap kan se ut och hur den Europeiska Landskapskonventionen definierar vad ett vardagslandskap är. Det diskuteras även vilken problematiken är kring begreppet vardagslandskap samt om bruksorter som Fredriksberg ingår i kategorin vardagslandskap.Berättelsen tar sin början i en bygd där svedjebruk och stångjärnsproduktion är starten till en blomstrande bruksbygd. En bygd som i början av 1900-talet har sin största näringsverksamhet inom papper- och massatillverkning.

Inclusion Body Disease hos boa- och pytonorm : diagnostiska metoder

Inclusion body disease (IBD) affecting boas and pythons is a serious and common disease. Boas can be clinically healthy carriers, which makes control of the disease difficult. The causative agent has not yet been confidently identified, and therefore there are no serodiagnostic tests available. Today, histopathologic examination of tissue biopsies is the recommended antemortem diagnostic method, but there are several disadvantages. The objective of this study was to compare the sensitivity of two diagnostic methods ? liver biopsies and blood smears, and to evaluate ultrasoundguided needle biopsy of the liver.
