Elevers arbetsklimat, ämnesintresse och medelbetyg i årskurs 9 : Om sambandet mellan dessa tre viktiga aspekter i skolans verksamhet
In the Swedish governing document for the mandatory school (Lpo94) it is laid down that The school shall strive for being a living social community that gives safety and the will and desire to learn. The social community and the social relations in the school everyday existence are thereby without hesitation very important for the students' learning. The teacher always wants to engage the students and create order, comfort and a good work environment. In this essay, the relationship between students' work climates, matter interests and average grades is studied. This gives understanding and awareness in these important parts of the schools´ daily activity.
Fuktproblem i sydöstra Asien
The author has, with the help of AK Consultancy Indoor Air AB, formed a series of questions regarding moisture problems in buildings and how these are handled in extreme climates with high temperatures and a high relative humidity. Furthermore to analyse and indentify key material that makes a construction safe against moisture problems. Ventilation, AC and the choice of materials have in a later stage of the thesis been investigated to enhance the knowledge of moisture protection. The research for this report includes measurements on existing buildings, calculation models on the building envelope for analyses and the ingoing materials of the envelope. The health aspect of moisture problems related to ?sick building syndrome? has been included and interviews have been conducted to gather relevant information.A study of the American system, ASHRAE, American Society of Heating, Refrigeration and Air Conditioning Engineers and the standards used in Singapore has been made to highlight the difference.
Häckar för Norrland
I have observed that hedges are not as prevalent in gardens in the north of Sweden as in the south despite a number of beneficial qualities attached to their use. Consequently, the primary purpose of this essay is to examine the potential for the use of ligneous or woody plants as hedges in a cold climate. The aim of this study is to provide information about the various varieties of ligneous plants that can be used for both pruned and unclipped hedges in the north of Sweden. Because the hardiness of the ligneous plants is a vital factor here, only plants that are hardy enough to survive in the Swedish hardiness zones V to VIII are included in this study. Roses, dwarf shrubs, conifers, bushes with a final height of less than 1 metre and plants that ?bleed? have been excluded.

It is shown how irrigation scheduling and irri-gation technology together increase the irrigation efficiency..
Pricing Credit Default Index Swaptions A numerical evaluation of pricing models
This study examines the background and nature of the credit default index swaption (CDIS) and presentsrelevant methods for modelling credit risk. A CDIS is a credit derivative contract that gives the buyerright to enter into a credit default index swap (CDS index) contract at a given point in time. ACDS index, in turn, is a multi-name credit default swap (CDS). Within the eld of research, thisthesis identi es the CDIS pricing models presented by Jackson (2005), Rutkowski & Armstrong (2009)and Morini & Brigo (2011) as the most recognized and developed. These models are evaluated byreconstruction in a numerical software environment.
En union, ett samarbete och en valuta i kris : En kvantitativ studie om Spaniens och Sveriges mediala framställning av euro- krisen inom EU
AbstractTitle: A union, a collaboration and a currency crisis- a quantitative study of the media coverage of the euro crisis within the European Union in Spanish and Swedish newspapers.The purpose of this study was to see whether Sweden and Spain ?s differences in media climates and relations to the euro crisis would affect how the story was portrayed from a narrative perspective. Did the coverage differ between the two countries and who got to comment on the situation in the media were two of the questions I strived to answer. I also wanted to see how the coverage reflected on the situation that the euro crisis has created.In this study I used a number of theories that I based my research on. The main theories I focused on was about different media systems and Sweden and Spain ?s relation to the euro crisis.
En villaleverantörs möjlighet till etablering i Finland : analys av för- och nackdelar
The construction market has, as a result of the crisis in Europe been uncertain in recent years. During the year 2013, the construction will be stabilized, in particular Finland. The geographical proximity between Sweden and Finland and similarities in cultures and climates makes Finland a coveted market for many Swedish companies.Differences in national regulations and guidelines, which are produced by the authorities in different countries, are examples of barriers that may hamper the process, including for Swedish villa suppliers, to establish themselves on the Finnish market. It may be useful when facing a new export drive, to look up what similarities and differences there are between the countries building codes, to prevent mistakes and unnecessary costs to the project work..
Broiler production in Zambia - management, growth, diseases and welfare
Successful broiler production in Hot climates requires knowledge of how birds are affected by heat stress. It is important with access to water and good ventilation to facilitate coping with the heat. It may be useful to reduce the consumption of feed during the hottest hours of the days, which together with a few hours of extra light available could improve both productivity and animal welfare.
The vision in birds is superior to that of humans and most other mammals. Continuous light and light with low intensity can cause eye injuries, affect the eye development in young chicken negatively, as well as provide increased incidence of foot pad lesions. Access to light affects the production but also the welfare of birds.
Kalvhyddans utformning : påverkan på kalvens hälsa och komfort
This paper aims to, through a literature review, examine how to best design and adapt calf huts to meet the calf's physiological requirements and reduce the infection pressure for enteric and respiratory diseases. It illuminates how the calf relates to different temperatures and climate, which temperature control mechanisms it uses and its ability to perform these regulations, as well as providing a summary of the past decades´ research on the calf huts housing system. These two theory chapters, along with a concluding discussion, provide a better understanding of how to, especially in temperate climates, design the most suitable calf hut, which cater to the calf's both thermal comfort and physical health. The literature suggests that the calf's own temperature control works well to counteract the temperature outside the desired range, and that one of the most important factors rather is ventilation of a calf hut, which reduces moisture and pathogens. The conclusion of this paper is mainly that there is not an obvious way to place and construct a calf hutch and that most design principles contribute to both positive and negative effects simultaneously.
Validation of realtime-PCR of Fusarium avenaceum for detection in wheat
Mould is a common contamination in cereals. The growth of mould can stimulate mycotoxins production andsome of which at critical concentrations cause health problems in humans and animals. Fusarium is one of thefungus species that has been found in crops and can cause major problems for farmers such as reduced harvestand economic losses. A group of Fusarium species, Fusarium avenaceum, Fusarium poae and Fusariumtricinctum express a mycotoxin, enniatin. The limited information available today about enniatin-forming fungiis that they grow out on fields of wheat in colder climates.
Muntliga förmågor, vad är det? : En analys av möjligheterna kring bedömning av elevers muntliga förmågor i samhällskunskap
Through teaching, pupils are given the opportunity based on their personal experiences and current events to express and consider their views in relation to others who hold different views. As a result, pupils should be encouraged to get involved and participate in an open exchange of views on societal issues (Skolverket, 2011d, s. 189). To assess pupils orally in the subject of civics in primary education is an unexplored field, which makes this field relevant to explore. There are numerous researchers? who with the help of deliberative methods, formative feedback, formative assessment and studies regarding classroom climates whom all speak positive about using discussion/dialogue in education to upraise and develop learning among pupils.
Felkällor och systematiska avvikelser i kvalitetsuppföljningen av tidnings- och journalpapper
I papperstillverkning ställs det krav inte bara på kvalité och kvantitet utan också att stickprov från produktion utförs och tas hand om på ett korrekt sätt. Från det att ett stickprov tas ut och undersöks på brukets laboratorium kan en del källor till förändringar på provresultatet uppstå. Sådana förändringar kan uppstå för det första vid hanteringen av stickprov från pappersmaskin och provens transportering till laboratoriet och för det andra vid laboratoriets hantering och uppföljning av kvalitén. En annan faktor som kan påverka stickproven är klimatet. Årstiderna vår och höst är de tider som proverna kan påverkas mest.

Minskad trädtillväxt under Lilla sitiden? : En dendroklimatologisk jämförelse mellan nutid och 1600-talet invid trädgränsen i norra Skandinavien
During the period called Little Ice Age (1400 ~ 1900) the climate of northern Europe was in an annual year-basis overall colder than it was before and after that period. The numbers of short, cold and rainy summers and long, bitter-cold winters where often repetitive under the approximately 500-years the period lasted. In Scandinavia, the coldest time during this period is estimated to have started around the end of the 16th century and lasted to the beginning of the 18th century. Trees growing at the tree-line are limited by temperature for their annual growth and hence showing differences of growth during changes in the climate, a method called dendroclimatology. The variations of growth can be read in the tree-rings either by analyze the width of the ring or by look into the density of the wood and is used to reconstruct past climates.
Vindkraft och elbilar på Öland år 2020 : Är smart laddning av elbilar lösningen på ett framtida flaskhalsproblem?
The Island of Öland has one of the best wind climates for land based wind power in Sweden. An objective for the Island is to become self sufficient using electricity from renewable source of energy such as wind. There is currently 55 MW capacity installed on the Island and it is estimated that grid congestion will occasionally occur if more than 135 MW was installed.The aim of this thesis is to investigate he possibilities for load management by smart charging of electric vehicles, EV. The definition of smart charging is that the charging is done to some extent with an ICT-system, (information and communication technology) that correlates wind electricity generation to the charging of electric vehicles. The purpose is to avoid grid congestions on the sub-sea cable that connects Öland to the mainland because that in turn would curtail wind energy production.
