Stabilisering av betongstommar : Beräkning av en ekvivalent beräkningsmodul med hänsyn till samverkande kort- och långtidslast
Vid stabilisering av betongstommar är det komplicerat att välja en korrekt elasticitetsmodul. Detta då stommens laster verkar under både kort och lång tid. I detta examensarbete utförs en noggrann kryptalsberäkning för varje plans vertikala element, där hänsyn tas till den varierande byggtiden. Utifrån det analyseras kort- och långtidslaster med respektive elasticitetsmodul för att erhålla en ekvivalent elasticitetsmodul som tar hänsyn till de olika belastningstiderna. Denna elasticitetsmodul bestäms efter förhållandet mellan stommens knäcksäkerhet, snedställning och den vindlast som verkar på byggnaden.Den ekvivalenta elasticitetsmodulen ligger till grund för mer noggrann indata än tidigare vid stabilitetsberäkningar och redovisas i diagram som sedan kan användas i det praktiska ingenjörsarbetet.Där inget annat anges utförs beräkningar enligt Eurokod 2.Där inget annat anges är figurerna ritade av författarna..
Dikten i "den nya fredens värld" : Litteraturdebatt i tidskriften Samtid och Framtid 1944?1949
This thesis analyses the literature debate in the overlooked Swedish magazine Samtid och Framtid 1944?1949. The magazine was first published at the end of World War II on the initiative of publisher Johan Hansson. After an interesting start, the terms of the debate in the magazine were changed after a power struggle on the editorial level. Thus, the magazine never became the influential arena for literary discussions that it first had potential of becoming.
Strategisk marknadsföring av produkter av rapsolja :
The background to this study is to find alternative ways of size rationalization. My vision is to
take the basic conditions and make the best and most profitable of them. I have chosen press
of rape oil because it?s interesting and the investment to get started is relative small. The
opportunity to use outmoded and unrational buildings which often are found at many farms to
something that gives money instead of costs money is also an argument.
Självkompakterande betong : Ytjämnhet utan efterbehandling
Betonggjutning är ett tungt moment inom byggproduktion och entreprenörer har länge använt betong med flyttillsats för att få en mer lättarbetad betong. Ändå har det krävts långa arbetspass och många tungarbetade moment. Efter lasernivellering, vibrering, slodning och glättning har man kunnat uppnå en yta som nästan är helt jämn. Dock ej så jämn att avjämningsmassa kunnat elimineras för att inte få sviktande parkett eller buktande plastmattor.Självkompakterande betong (SKB), eller vibreringsfri betong som man först kallade den, forskades fram på 80-talet i Japan och dök upp i Sverige i slutet på 90-talet. Det är en betong som innehåller en flyttillsats och en så kallad filler vars gemensamma egenskaper ger en betong som har bibehållen homogenitet samtidigt som den fyller ut formen och omsluter armering endast genom gravitationskraften.
En longitudinell studie om lagervärdering : En studie ur ett samhällsperspektiv
This study concerns how Muslims are portrayed in a choice of twelve news articles from Swedish dailies and tabloid newspapers on the aftermath of the film Innocence of Muslims published on YouTube. All articles are distributed in the newspapers Aftonbladet, Expressen, Dagens Nyheter and Svenska Dagbladet in the period of September 11th, 2012 until September 30th, 2012.For this study, a qualitative text analysis has been embraced and focus has been on van Dijk?s Critical discourse analysis to the texts, with additional features from semiotics applied on the images.The theories consist of Critical discourse analysis, hegemony, ideology and power, postcolonialism and stereotyping.In the qualitative content analysis, concrete examples from the articles are retrieved and commented. These have been divided into various themes, which are trends that the authors have been able to distinguish in the analysis.The result shows that Muslims in the analyzed newspapers are portrayed as the others, unimportant and extremely religious, in a negative manner rather than a positive. Moreover the press has tendencies to generalize Muslims as a group.

Odlingsstrategier på organogena jordar : en studie om beslutsfattande bland KRAV-anslutna lantbrukare
This study examines how farmers certified by KRAV face proposed regulations on organic soils put forward by KRAV economic association among others, and how they are affected economically. These soils are, from an environmental perspective, interesting as a target for production regulations as they cause greenhouse gas emissions through decomposition of organic material when cultivated. The regulations advocate that organic soils should be grown with pasture where soil cultivation is only allowed every fith year which implies that possible adjustments of cultivation have to be made in order to fulfill the regualtions. Collection of data have been made through a questionnaire sent out to 574 farmers certified by KRAV. The answers have been analysed using a decision making model and statistical findings suggest that proportion of organic soils, type of production, economic conditions and farmers? goals and values have an influence on whether the regulations and potential cultivation adjustments have been considered or not.

Skydd mot yterosion i slänter av finmorän
Slopes in fine till soils are exposed to surface erosion due to rainfall, snowmelt and upland water sources. Large areas of road slopes are therefore covered for surface erosion protection. Preventive methods like ditches and trenches are also being used. Silt tills are particularly troublesome since the water can bring the soil into suspension and cause mudslides. Different methods for erosion protection have been studied in this work, with the emphasis placed on rockfill covering. The need for and the dimensioning of this type of covering has been examined in literature and field studies.
Att utkräva ansvar - en analys av Vattenfalls verksamhet i Tyskland
With the expansion onto the international market almost a decade ago, Swedish energy corporation Vattenfall began it's breaking and burning of coal on German soil. Criticism aimed at Vattenfall peaked in the mid 2000s with the revelation of large quantities of carbon dioxide emissions and the re-location of villages and graveyards in German states Brandenburg and Saxony. The purpose of this thesis is to show where the responsibility for these activities lie. By analyzing the history of, and the political debate surrounding, Vattenfall, I will show that the prevailing policies of right- as well as left-wing parties in the 20th century were all, regarding this matter, market oriented. I will also show that these market promoting policies made possible a situation where the transparancy of, and state control over, Vattenfall were close to eliminated.
Hypotermibehandling av nyfödda barn vid Universitetssjukhuset Örebro
AimThe compulsory school attendance in Sweden means that all children are obligated to go to school. This makes great demands on those who work in the school, especially the teachers. Schools are complex units. In school, teachers face all kinds of ethical dilemmas on a daily basis. The aim of the study is to enlighten how different teachers would act differently, if they were facing the same dilemma in the PE-lessons and why this knowledge is important to our profession.MethodThe data was collected through interviews to make a qualitative research.
Möjligheter att förutsäga kvävegödslingsbehov i höstvete med Yara N-tester
The Yara N-Tester is a handheld chlorophyll meter which can be used in several different
crops as an aid to determine if there is a need of complementary fertilization with nitrogen
(N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha.
The possibility to assess the need of N depends on the strong relation that exists between
chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series
?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was
carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters
ability to estimate the need of N in winter wheat, will be presented for the years
2008-2011.
Kvickrotsstudier: 1. Kvickrotens reaktion på myllningsdjup, kvävemängd och kväveplacering i konkurrens med gröda. 2. Reducerad glyfosatanvändning på trädad åkermark :
1. Reaction on burial depth and nitrogen availability and placement in competition with a crop
In this trial it was investigated how couch grass (Elymus repens) changes its ability to compete in stands of wheat and barley with different burial depth and different amounts and placement of nitrogen. More knowledge in this area can be valuable in the attempt to decrease the use of herbicides and still keep the weeds under control.
The trial was carried out in the summer of 2004 as an outdoor pot experiment. The pots contained 15 litres of soil with a surface of 0,06 m2.
