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..
Gene expression from a cold-treated Swedish isolate of Haemonchus contortus
Totally 84 differentially expressed mRNA clones from infective L3 larvae of the parasite Haemonchus contortus, a blood sucking nematode, were analyzed with single strand hybridization assay (SSH). Altogether 79 clones were sequenced, edited, and compared with proteins found via BLAST in GeneBank. The aim was to investigate gene expression and potential protein expression following storage at 5 °C for 32 weeks. mRNA was extracted from fresh and stored L3. The SSH derived products were cloned into E.
Bättre utnyttjande av nya och befintliga förrådslokaler på SSAB Tunnplåt
The purpose of this assignment at SSAB Tunnplåt in Borlänge was mainly to investigate and describe the circumstances for the spare parts stored in storage facilities within the area of operation. Even new facilities which could serve as storage rooms and their opportunities for storing spare parts were an important part of the investigation. This because of the need for improved storing of spare parts. Furthermore, market offers where reviewed for storage of spare parts in more tailored designs. The work will culminate in proposals for improvement which is of importance for the development surrounding the storage and handling of spare parts.
Äldreboendet på Zakrisdal : En studie om solvärme med säsongslagring
A home for elderly is planed to be built at Zakrisdal, Karlstad, Sweden. The heat source for the building was at the time not determined. In order by the local government of Karlstad this report is meant to examine if the need of heat could be provided only by solar heat combined with a seasonal heat storage. The problem to solve is, if the need of heat from the home for elderly is provided from only solar heat, whitch dimensions of the solar collectors and the storage is needed?.
Faktorer som påverkar sockerförlusten vid lagring av sockerbetor : inverkan av lagringstemperatur, lagringstid och vattentillgång
This thesis is a part of the project "Sustainable harvesting and storage of sugar beets, more sugar to practice". The work has included a large part of practical experimental work with weight measurement, graduation and storage planning. The aim of the project is to be able to see whether the cultivars react differently in different storage conditions. The project has included storage under controlled conditions to give as accurate results as possible. To be able to mimic the farmers own preconditions the samples was harvested with a conventional Holmer.This project has two parts, one concerning the nature, time and temperature on storage where a number of different cultivars where investigated during three different recording times, two different temperatures and controlled in a controlled environment.
Bioenergi från röjningsgallringar : en jämförande studie av fyra flödeskedjor från avlägg till förbrukare
When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.
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.
Long-term Storage of Starch Potato and its Effect on Starch Yield
Lyckeby Starch AB is a farmer-owned company that produces products based on potato
starch. In order to increase their production efficiency and their international competitiveness
the company is investigating the possibilities of keeping their factories open longer. To
achieve this, potato has to be stored for a longer period of time than what is practiced today.
Starch potato is usually stored in large piles covered by straw and plastic, either in the field or
on the farmyard.
The objective was to examine in what way starch yield (starch content*tuber weight) in
three different potato varieties was affected by storage in two different types of storage piles.
The potato was stored for three months in total and starch content and tuber weight were
controlled throughout the period. Stored tubers were also visually examined and prescense of
mechanical damage as well as wet rots and dry rots was recorded. Bacteria and fungi were
isolated and identified.
In general, varietal differences were greater than differences between the storage piles.
Latent värmelagring i vattenburet uppvärmningssystem med elpanna för byggnadsapplikationer
Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.
Energy efficient storage of biomass at Vattenfall heat and power plants
Storage of biomass is often associated with problems such as heat development, dry
matter losses and reduction of fuel quality. The rise in temperature can potentially
cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles
can cause health problems in the surrounding. The dry matter losses and reduction of
fuel quality can have economical effects. The aim of this thesis project is to develop
guidelines on how to store large amount of biomass at Vattenfalls heat and power
plants in an optimal way.

Lagring av kyla med horisontella markvärmeväxlare för kylning av koncepthus i Mellanöstern
Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.
Sjöfartsmuseets tavelsamling Att flytta en samling och planera ett nytt magasin
This paper deals with the problems that can occur during the move of an entire collection. Thecollection discussed is located at the Gothenburg Maritime Museum and it has beenconsidered to move the collection to a storage where the other collections of the museum iskept. No decisions are taken but this is a suggestion of how it could be done. The collectionwhich is studied contains of different kinds of objects like for example paintings, work onpaper and photographs. The whole moving project is looked into and all the different parts areanalyzed.
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.
