Lycksabäcken, ett riksintresse med komplext deglaciationsförlopp : Presentation av ett möjligt scenario över deglaciationen i området
The area of Lycksabäcken northwest of Lycksele is a national interest of natural conservationbecause of its geological values with many unique landforms. Many of these landforms indicatethat the deglaciation process in the area was very complex. However, the deglaciation process inthe area has not previously been fully understood. The aim is to add to the knowledge of theevents that took place during the last deglaciation. To do this, the glaciofluvial landforms in thearea were mapped by studying aerial photographs with a Wild Aviopreter and a five-day fieldinventory of key areas for the interpretation.
Deglaciationen av ett område på västra Grönland : Deglaciationen av ett område på västra Grönland
The aim of this report is to describe the deglaciation in an area on west Greenland in the vicinity of Kangerlussuaq. To do this, the geomorphological landforms were mapped by studying areal photographs and by a two week field study where key areas were examiend. The landforms were transferred to a map using ArcGis and each key area were interpreted.The majority of the geomorphological formations were formed during the last deglaciation and consists of morain ridges, kettle topography in both till and glacifluvium, glacifluvial deltas, two fossil sandurs, and lateral terraces. Based on key areas and an inversion model a geomorphological map was created to illustrate the deglaciation, using the least complex explanation of the genesis of the landforms. The results show that the ice played a major role by damming lakes which enabled formation of many meltwater chanels and delta formations on higher elevations.
Moräntäckta rullstensåsar i Västerbottens inland
The purpose of this study was to map the distribution of till-covered eskers in the inland of Västerbotten County in northern Sweden. The top layers of big eskers along the valleys of Öre River, Ume River and Vindel River were investigated through shallow digging. Findings were investigated through field assessment and soil analysis and many locations with till-covered eskers have been identified in Västerbotten's inland in this survey. The till covering the eskers has probably been transported only short distances and has its origins in glacifluvial material. The pattern is not consistent and there are areas where till does not cover the eskers.
LIDAR-analys av flygsanddyner i Västerbottens inland : Har dynmorfologi bildad under tidigare interstadialer bevarats i landskapet?
The aim of this study was to map the prevalence of aeolian sand dunes in Västerbotten, northern Sweden to find dunes formed during earlier deglaciation phases, which was then preserved in cold-based conditions during the youngest stadial of the Weichselian glaciation. These preserved dunes were expected to be covered by a layer of till and have a rather faint morphology compared to dunes formed during the Holocene. Consequently, high resolution LIDAR-derived images from the Swedish mapping, cadastral and land registration authority (Lantmäteriet) was used to detect the dunes throughout an area covering most of Västerbotten, above the highest coastline and below the mountain range. The analysis resulted in several new findings of aeolian dunes compared to the findings in the quaternary soil map created by the Geological Survey of Sweden. Despite the fact some of the dunes at the LIDAR-derived image had a strange faint appearance, it was quickly evident during the fieldwork that the aeolian sand was not covered by till on any of the dunes visited.
Valsningsteknik för extremt höghållfasta tunna stål
New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.
Indianen och kalla kriget : Audiovisuella representationer av kalla kriget 1965-1986
The similarity between the Russian and the Indian, in a Cold War context, may be ambiguous considering the ethnic-social variables and the period in time from where the Indians relate. However, by analyzing these, as well as other, characters in the exhibition of movies, we could learn something about the ideology of the time from which the movies derive.This study examines ideology and movies in the Cold War era and concludes that the Indian, for example, may be representing the values of the common public enemy, originating from the Cold War ideology. The movies examined, regardless of influence of distinct Cold War themes or lack of such themes, carry attributes that give evidence of typical Cold War ideology. The fear of communism and common enemies connected to a Cold War context, the thought of America as the land of the free ? with the horizon in the ending of the movies as metaphoric to freedom ? and the moral rhetoric that connects to the American thought of a duty as a global savior, are all signs of the Cold War ideology.Even though the messages are somewhat clearer and more distinct in the movies with Cold War motifs, the fact that ideology is projected through other movies as well should be considered essential for the continuing study of movies as cultural artefacts..
Historiografi och paradigm i forskningen om kalla kriget : En komparativ analys av diplomatihistoria och internationella relationer
Adopting a socio-cultural approach to the study of cold war historiography, this master?s degree essay is a comparative study of the two main disciplinary fields of cold war scholarship, diplomatic history and international relations theory (IR). The study applies the theory of scientific development formulated by Thomas Kuhn and the concept of paradigm on the field of cold war research.Diplomatic history and IR shows many similarities in their development, and in the importance different schools has had in scholarly debate. These different schools are analysed as paradigms, a concept that has been more willingly adopted within IR than in diplomatic history. The transition from what historian John Lewis Gaddis has termed Old Cold War History to New Cold War History is discussed in terms of paradigms and paradigm shift.
Kommunismens ansikte : Skildringen av kommunismen som ideologi och kommunistiska regimer i svenska och norska gymnasieläroböcker under perioden 1951-2011
This paper presents an analysis of history textbooks used in schools in Sweden and Norway. The intention of the research was to study how the history textbooks describe communism and communistic dictatorship mainly during the cold war. The result of this study is that there were no big differences between Swedish and Norwegian history textbooks, but there are, however, some differences in how communism was described between the authors and also over time. Mostly, the books that were written in the post cold war period were somewhat more critical to communism in the eastern Europe (even thought they mainly handled with Stalin´s communism. And they also set quotationmark between Stalin´s communism and the nazi terror during World War two..
ALTERNATIVA ASFALTSBELÄGGNINGAR : Möjligheten att använda icke petroleumbaserade bindemedel
This report investigates the possibility to use non-petroleum based adhesive (biobitumen) in asphalt. The main reasons for replacing bitumen are the fact that oil prices are rising, the threat of peak oil and the fact that the asphalt industry is becoming more environmentally friendly.The main purpose of this report is to investigate whether there are any non-petroleum based adhesives on the market. If so, how can they be used? The questions covered are:? Are there any other alternative asphalt coatings available?? Can bio-oils be used in asphalt?? If the bio-oils can be used, what are the details their properties?? How does a cold climate affect the bio binders?? What is the Swedish asphalt industry?s opinion about bio asphalt?The project was concluded through literature studies, consultations with people in the asphalt industry and through several interviews.The conclusion of this report is that there are some existing non-petroleum based adhesives on the market. They are mainly used for bike paths, sidewalks and parkareas.
Från neutralitet till öppenhet? : En studie av säkerhetspolitikens utveckling i Sverige efter kalla krigets slut
Abstract Title: Från neutralitet till öppenhet? ? En studie av säkerhetspolitikens utveckling i Sverige efter kalla krigets slutAuthor: Jens KindhSupervisor: Patric LindgrenLinnaeus UniversityDepartment of Political ScienceSpring term 2012 When the Cold War ended, a new security situation was unfolded in Sweden. The purpose of this thesis is to describe and compare how the Swedish security policy is organized and how it has changed since the Cold War ended. To do that, I?m going to try answer the following questions:How is the Swedish security policy organized?What defence resolutions have affected the Swedish security policy after the Cold War ended?How has different political actions made its impact on the Swedish security policy after the Cold War ended?My theory is to try explain how the Swedish security policy has changed after the Cold War through a realism security perspective called traditional security, which refers to a realistic construct of the states security policy.
Clash of Civilizations Myt eller verklighet?
In 1989 the Cold War ended and in 1991 the Soviet Union ceased to exist, over night the ruling paradigm of International Relations was obsolete. What would happen now? Samuel Huntingtons answer was that in the future, cultural identity would be the most important factor behind international conflict. And that the threat of world war would come from clashes between civilizations instead of clashes between ideologies like during the cold war. Was he correct? This thesis is an attempt to find out if Huntingtons theory was right in its predictions of the world to come.
Fuktstudie om uteluftsventilerade vindar med beräkningsprogrammet Simple Cold Attic Model från Annex 55
Fuktskador på uteluftsventilerade vindar är ett ökat problem, i det mer miljömedvetna Sverige. Genom tjockare vindsbjälklagsisolering minskar både energiförlusten genom bjälklaget och uppvärmningsbehovet i huset, men hur många funderar på vad som händer med det förändrade klimatet på vinden och hur det kan påverka fuktförhållandena i utsatta delar av konstruktionen.Studier från Chalmers Tekniska Högskola har framställt ett fuktberäkningsprogram för uteluftsventilerade vindar vid namn Simple Cold Attic Model. Programmets funktion och potential har prövats i denna rapport genom en beräkningsanalys av en uteluftsventilerad vindskonstruktion. Försök till att förbättra fuktsäkerheten i konstruktionen har utförts och redovisas i rapporten. Studien har påvisat att den studerade konstruktionen inte är fuktsäker om den uppförs i Stockholmsområdet. Det visades även att aktiva val i konstruktionen kan förebygga fuktskador. Studien har påvisat vikten av inte beräkna med medelår för klimat och hur det påverkar beräkningsresultatet av mögeltillväxt.
The effect of cold stratification on germination in 28 cultural relict plant species : with the purpose of establishing germination protocols
Cultural relict plant species from the Nordic countries have been collected by the Nordic Genetic Resource Center (NordGen) for the purpose of conservation. To ensure high seed vitality in store, regular germination tests need to be conducted. It is important to get a correct viability status, but the knowledge of seed dormancy in the cultural relict plants is often poor. The objective of this study was to investigate how seed dormancy is affected by cold stratification. The study includes 31 accessions from 28 species with the purpose of establishing germination protocols.
Nordiskt försvarssamarbete : Är det en ny företeelse eller en fortsättning på det som tidigare ägt rum i hemlighet?
There are changes in Sweden's foreign policy, and Sweden is no longer a non-aligned and neutral nation. Sweden has expressed a willingness to actively participate in creating peace and stability in the world by giving and receiving military assistance in case of war, crisis or disaster. This is described as complete turnaround in Swedish policy compared to the neutrality and non-alignment during the Cold war.However new research shows that defence cooperation is not new in the Nordic region. Sweden cooperated secretly with Denmark and Norway, two NATO countries, about co-operative defence of Scandinavia during the Cold War.Is our historical picture wrong and what we perceive as new and revolutionized not particularly new? Is today's open Nordic defence cooperation a continuation of what was done in secret during the Cold War? The essay investigates and compares two different Swedish defence cooperation?s where one was previously secret and the other is open.
Luftvärnets verkanssystem i Utlandstjänst
This paper aims to analyze if ground based air defence of the Swedish Defence Forces is sufficiently equipped to protect units serving abroad. The Swedish ground based airdefece has its roots in the era of the cold war but the focus of Swedish Defence Forces has shifted from defending Swedish territory to peace keeping and peace enforcement in foreign countries. First I will take a look at the base factors for ground based air defence units serving in a peace keeping or enforcing mission and then use this to define what abilities you would like to have in a ground based air defence system. Finally I will compare these abilities whit the abilities of the ground based air defence systems that are in use whit the Swedish Defence Forces.My conclusion is that the question can´t be answered on a generel level but every mission has to be analyzed individualy.The author of this paper is Cadet Tobias Jönsson studying at the The Armed Forces Technical School to become an officer in the Swedish Defence Forces..
