This study aims to assess the normal inflow of extraterrestrial chromite to Earth. The results from the investigationare compared to earlier studies of middle Ordovician Orthoceratite Limestone in which 1 - 3 extraterrestrial chromitegrains ( >63 ?Êm ) per kilogram limestone were found. These values have been interpreted as evidence of a twoorders of magnitude increase in the flux of extraterrestrial matter to Earth during a part of middle Ordovician.From an early Paleocene marine sedimentary sequence with known sedimentation rate in Zumaia, northernSpain, 90,5 kilogram of condensed limestone, dated to about 63 Ma, was sampled. The limestone was dissolved inhydrochloric- and hydrofluoric acid and the residue was sieved and searched for opaque minerals under the binocularmicroscope.

The Swedish geographer Gerd Enequist (1903-1989) left behind great amounts of private and work material when she passed away. This was donated to the University Library of Uppsala, Carolina Rediviva, in three different accessions. This resulted in three different record. The subject of this report is the progress of assembling these record into one complete record.The registering led to many important decisions such as the role of Provenance and the relation of private and public documents. Above all the special nature of personal archives have been a topic of discussion.

This thesis at the Institute for Language and Folklore has as its purpose to lay a foundation for a continuinginventory work. The tasks I have performed during my time there was to create an archival description, anintroduction to the material and a process map showing the process of incoming delivery of documents. The aimwas never to finish the list of work, but to structure the material to get an insight into the material and to theproblems that existed within. The documents are of a very unique nature and require that the archivist is familiarwith and have knowledge of sign language. One of the problems I encountered was how fragmented the materialwas.

In the old university of Turku there were written about 4 400 theses. About 1100 of them havefound their way to Linköping in Sweden. This paper describes these theses, new variants whichwere found and some characteristics of their Provenance. They are compared with the largebibliography over theses from Turku by Vallinkoski. A couple of theses with completeinformation which have not been available since 1827 were found.

There are several objects of age whose Provenance and history has disappeared with time. The purpose of this thesis is to find out which analyzing methods that gives results and how the different methods can be combined and /or established in each other. The investigations centers around an embroidery, belonging to Tämta church, with unknown origin, use and age. The embroidery is long and narrow with applications in the form of dragons and eagles on a ground of velvet cloth. The dragons and eagles are covered with metal threads.

I have for my one year master's thesis worked on arranging and cataloging the archives from the missions stations of Musana, Congo-Brazzaville and Sundi-Lutete, Congo-Kinshasa, belonging to the Swedish Missions Church (Svenska Missionskyrkan). The archives contained records written in Swedish, French and Kikongo, from primarily the years 1910 until 1961. Records have though been found that adhere from both prior to and after these years. These archives are deposited at the Swedish National Archive and it was therefore important to take the opinions and regulations of both parties into consideration, as well as relying onto archival theory.The archives were initially scattered and had in some parts been organized by an archivist without formal schooling. The major difficulties in this work has therefore been to establish the Provenance ? to which creator the documents belonged to, and also to decide to which degree the principle of the original order should play a part.

År 1972 skickade NASA upp en rymdsond, kallad Pioneer 10, ut i rymden med en bild fastsatt på sondens utsida. Bilden var ett meddelande till utomjordiska varelser och illustrerade information om människan och jorden. Med bilden som en visuell utgångspunkt har jag designat en workshop för åtta gymnasielever i två olika grupper som fått i uppgift att skapa en animation att skicka upp i en rymdsond idag. Genom att omformulera den digitala berättelsens metod har jag velat undersöka hur deltagarnas process och animation kommer att formas om utgångspunkten är visuell. Jag har utifrån mina didaktiska designval undersökt vad deltagarna har gjort för egna val, material och tillvägagångsätt de använt sig av. Under projektets gång har jag samlat in empiri i form av ljudupptagningar, filmmaterial, fotografier och fältanteckningar samt analyserat deltagarnas animationer.

This essay is based on the work of arranging and making an inventory for an archive consisting of records from the Board of Education (Utbildningsnämnden) within the administration of the County Council in Uppsala, Sweden. This archive is kept at the County Councils Archives in Uppsala where I have done the work. I have documented the process and discussed the complex of problems relating to it. In this particular case the issue of limitation of the office of origin and the respect of the fonds, or the principle of Provenance, have been of interest. This is due to the fact that the records had been rearranged and mixed with records with other origin related to the Board of Education.

Recent statistic shows that about 28% of adolescents living in Stockholm drink alcohol at such a high level that their consumption counts as risky drinking. The correct term to use in this matter would be binge drinking adolescents.  In the more wealthy areas of Stockholm this group of binge drinking adolescents counts for as much as a third of the population. In contrast, the adolescents living in exposed areas do not drink nearly as much. Binge drinking adolescents in these areas only counts for 15%, nearly half as much as in the wealthy areas.In light of this the intentions of this study is to investigate which explanatory factors that can clarify the range-rated differences in binge drinking between adolescents in Stockholm.

Sitka spruce (Picea sitchensis) is a tree species that have its natural distribution along the West Coast of North America, from Alaska in the north to northern California in the south. Sitka spruce is a typical coastal tree species that can reach heights up to 85 meters and occurs in single pure as well as in mixed stands. The main purposes of this study were to describe the Sitka spruce growing characteristics and the volume production in comparison to spruce (Picea abies). The possibility to predict future volume production by using prognosis tools designed to be used on spruce were also studied. The material that has been used in this study are permanent sitka trials established by the Faculty of Forestry fixed Sitka trials and also material gathered in this study. A literature study was also carried out in order to determine the Sitka spruce growing characteristics. Sitka spruce has a high adaptation and a high volume production on a broad scale of soil types. The tree species is a pioneer species that has a fast early growth and in combination with sharp needles it is less susceptible to animal browsing than spruce. The factor that is the single most limiting factor for where the Sitka spruce can be planted is frost. This factor can be limited by using plant material with a well-suited Provenance. According to the literature, the Sitka spruce has an average total volume production that is between 20-40% higher than spruce.

Sweden has almost 600 000 hectares planted with lodgepole pine, and large areas are soon ready to be clear-felled. The Provenances that have been planted are producing high level of permanently closed, so called serotinous, cones. In their natural setting, the Canadian boreal forest, these cones are opened mainly after crown fires when the heat make the resin between the cone scales melt, which releases the seeds. This is viewed as an adaption to the fire regimes that prevail over the natural distribution area of lodgepole pine. Because of the short flame-exposure that occurs in a crown fire, the seeds can survive.
