Effect of liming and free Ca2+ on Cd uptake of carrots, Daucus carota
The level of cadmium (Cd) in Swedish arable land has increased during the last century and the average concentration of Cd in the plough layer is today 0.23 mg/kg. The increase is mainly due to anthropogenic activities such as phosphorus fertilizing, liming, import of feed, and atmospheric deposition from industrial emissions. Cadmium in the soil will be taken up by crops and is thereby transferred to humans via food. Carrot is one of the crops of concern, both because it may contain quite high Cd concentrations and due to the large consumption in Sweden. In the body, Cd is stored mainly in the liver and the kidneys and may cause several diseases already at low concentrations.
Image i förändring : En fallstudie av SAS Sverige AB
During the early 1990´s, the Swedish commercial air traffic was de-regulated and the new market-condition made it possible for low-budget airlines to enter the Swedish market. The former monopolistic airline company, Scandinavian Airline Systems (SAS), was facing a new type of competition which had the advantage of offering much cheaper air trips than SAS. Adding the decrease of profitability that struck SAS as well as other airline companies after the terrorist attacks on the 11th of September, forced them to carry out a mayor reorganization programme. The programme, called ?Turn Around 2005?, was a direct economical measure that begun in 2002 and lasted until 2005 and resulted in a cost saving of 14,5 billion SEK as well as a notice or a transfer of 6000 employees.The purpose of this essay is to investigate if the opinion of the consumer, the image, corresponds with the profile that SAS wishes to mediate today.
Hot, våld och trakasserier : En studie om handlingsutrymme, politiska ledare och demokrati
Studies have shown that politicians are significantly more likely to become victims of violent crime than other citizens in Sweden. In fact increasing political rank and engagement are directly proportionate to increased risk for violence. Threat towards politicians is not only dangerous to the individuals involved but also to the democratic system as a whole.Political scientists the world over have done a lot of research on democracy, but I have been unable to find a single method or theory that examines how violence, threat and harassment affect political leaders and democratic systems.The aim of this study is to expand the existing model made by Tommy Möller, professor in political science. In his model he presents 11 factors that affect political leaders ability to act. My aim is to develop his model by adding a 12 th factor ?violence, threat and harassment?.
Vattenanläggningar som gestaltningselement i offentliga miljöer :
Water constructions - as a design element in public spaces is the title of this Master thesis, with a focus on waters function and meaning in the urban environment.
By way of introduction, mans relationship to places is described and the factors that contribute to the reality that we prefer some places more than others. A good place to stay is open but well defined, gives protection, offers a good view and is varying in topography and vegetation, together with contents of single landscape elements like visible water.
This study then continues to discuss mans relationship to water and its means for our wellbeing. Despite the fact that people have a different relations to water due to personality, background and age, it?s an element that raises positive feelings, interest and aesthetic pleasure for most people.
Trombocyträkning hos katt : en ny metod
Platelet aggregation is a major and common problem in blood samples from cats. This greatly affects the accuracy of counting of the platelets. Because of the difficulties in counting feline platelets, results for patients and reliable reference values for cat platelets are currently so inaccurate as to be almost useless in diagnosis of thrombocytopenia. In this study we used an effective method to prevent platelet aggregation. Blood was collected in CTAD test tubes and prostaglandin E1 was added to the blood sample.
Analys och dimensionering av robusta kilspårsförband
This master thesis comprises analysis and dimensioning of a keyed joint between a generator axis and a hub with aid from the FEM-software ANSYS Workbench 13.0.The generator axis is a part of a hydroelectric power station that generates electricity with a reactions turbine, a Kaplan turbine. The existing keyway consists of one parallel key with the width 90 mm and height 45 mm. Due to a planned increase of the power of the generated power with 32 % a design study was needed to see if the keyed joint would be suitable for the extra force. Because of the fact that the axis diameter is bigger than the standards covers/recommends a the keyway had to be re-dimensioned. In an earlier assignment from Skellefteå Kraft AB to Sweco Energuide the keyway was planned to be properly dimensioned, but no final solution was approved.During this master thesis a number of different numerical tests were made.
Utvärdering av den bärande tegel- och betongstommen i en byggnad från år 1916
This Master thesis is about a postal- and telegraphic building in Eskilstuna, Sweden. The construction methods for the specific building and buildings in general from the same time are described. The purpose of the report is to describe the loads acting on the building and how it has been built and why it has been rebuilt during the years. After this, possibilities of reconstruction and adaptation for today?s demands can be evaluated.
Scenografi för en landskapsarkitekt :
Stage Design is design for action and contains décor, side-scenes and properties, as well as costume and grease-paint. The one responsible for this is the Stage Designer, who together with the Director, creates the best conditions for the actors to perform in.
The stage, where the play takes place, could be either in a theater, an auditorium, or in another sort of room, at another place, inside or outside, and where the place itself inspires to theatrical performance and expressions. This type of theater is called Site-specific theatre.
Two examples of this is the workshop ?Skogen sjunger? (eng.

Jämställdhet i undervisningen : Några gymnasielärares syn på jämställdhet i läromedel och undervisning
The purpose of this study has been to look into and analyze the view on sex equality in textbooks and teaching media, and teaching of a group of upper secondary school teachers, through a gender perspective. The teachers teach subjects within social- and political science. The two questions that I wanted to answer are: What views do the teachers have on sex equality in their teaching? What views do the teachers have on sex equality in the teaching media (textbooks and other teacher media) which they have access to? Since I wanted to look into the teachers own views I chose unstructured interviews as the method of gather empirical information. To interpret the transcribed texts I chose the hermeneutic view of people as intentional.
Möjligheterna för Casabona-systemet
Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.
Blood compatibility of biomaterials made of recombinant spider silk
Native spider silk is an attractive lightweight natural polymeric material with a unique combination of strength, extendibility and flexibility. Synthetic, recombinant spider silk is an attractive biomaterial with several possible fields of application.
When a foreign material is introduced to blood, this can for example cause unwanted coagulation and complement activation.
The aim of this study was to investigate if coatings of heparin or albumin could improve the blood compatibility of films of recombinant spider silk and to develop an initial method to do so. Hypothetically, objects like pacemakers, stents and dental implants could be covered with spider silk films of high blood compatibility to reduce potentially harmful foreign body reactions caused by the immune defense. Increased blood compatibility would likely lead to improvements for both the individual patients and the society thanks to reduced load on healthcare institutions.
Our objective was to assess the blood compatibility of both functionalized and non-functionalized recombinant spider silk by evaluating coagulation and activation of the complement system of the immune defense.
Coagulation was evaluated visually on glass slides and complement activation was analyzed by measuring the concentration of the complement system mediator C3a in blood samples that had been exposed to the different materials.
This study introduces a non-toxic and easy performed method of improving the blood compatibility of recombinant spider silk films by adding a heparin coating.
Heparin coated surfaces had statistically significantly higher blood compatibility than uncoated surfaces. The effects of albumin coating of films were less clear compared to the results of heparin coated films.
Complement activation could not be evaluated because of high activation in all samples prior contact with the materials that were included in the study..
Renovering av Säteriet, Råda - Från miljonprogram till attraktivt bostadsområde
The homes that were built in the 60?s - and 70's are now so dilapidated and worn that they need thorough renovations. These renovations are expensive to implement for the landlords, which means that the funding for these renovations can create problems. Currently there are no government subsidies for these renovations. This report will examine how Förbo performed the renovation of Säteriet.
Effects of palmitic and stearic acids supplementation on milk yield, composition and milk lipolysis in dairy cows
When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of
added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups
resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate
(P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.
Byggnadens andra skepnad : En anpassning för att möta samhällets behov och krav
Population growth leads to an increased need for new buildings, both residential and commercial. The regulations of structural design also changes with time. From a sustainable community perspective it may be profitable if existing buildings, that no longer performs their original function, are reconditioned. Knowledge and understanding of the surroundings of the residence must be available. Regulations regarding accessibility to all has increased.
