Hoverfly communities in agricultural landscapes: a comparative study between habitat types

The worlds’ human population is continuously growing, and meeting the increased demand for food requires an increase of agricultural production. Agricultural ecosystems are of great importance for humans in terms of delivering provisioning ecosystem services, such as the production of food. The term ecosystem service is a function provided by natural environments, that are beneficial for humans. A

MRI as a potential method for detecting inflammation in eyes of epileptic mice

You might have heard the expression that the eyes are the window to the soul, but what if the eyes are also the window to the brain? What if you could see what happens in a person’s brain only by looking into their eyes? There is indeed a physical link between the eyes and the brain. The retina, the part of the eyes that is responsible for collecting incoming light, develops from a part of the b

The Design and Linearization of 60GHz Injection Locked Power Amplifier

The RF power amplifier is one of the most critical blocks of transceivers, as it is expected to provide a suitable output power with high gain, efficiency and linearity. In this paper, a 60-GHz power amplifier based on an injection locked structure is demonstrated in a standard 65 CMOS technology. The PA core consists of a cross-coupled pair of NMOS transistors with an NMOS current source. This st

A Sustainable Bredäng - Sustainable Densification of a Million Program Area in Stockholm, Sweden

Bredäng, a housing area in southwest Stockholm, was built between 1963 and 1965 as part of The Million Program, a Swedish government program to fix the housing shortage in the country. Bredäng is characterized by its green and blue qualities, but also by its many parking lots, poor public spaces, monotone architecture and storm water issues. Today, the housing shortage is once again an issue, esp

Det blev inte som planerat - En utredning om avbeställning och dess förhållande till hävning i entreprenadavtal

Beställarens rätt att avbeställa arbeten när denne ingått ett entreprenadavtal med avtalsgrund i AB 04 utreds och analyseras i denna uppsats. Vidare undersöks förhållandet mellan avbeställning och hävning. Detta görs med hjälp av en traditionell rättsdogmatisk metod. Författare på området synes vara överens om att beställaren har en avbeställningsrätt. Men, om denna kan anses följa direkt av AB The buyer´s right to cancellation of works in a commercial construction contract due to AB 04, is analysed in this paper. The relationship between cancellation and termination is also examined. This paper is based on a legal dogmatic method. Authors in this field agrees that the buyer is entitled to cancellation of works. But they do not agree if this right follows directly from AB 04, by outgoi

Dissolution kinetic study of limonene in supercritical carbon dioxide by in-situ Raman spectroscopy

Understanding the dissolution kinetics is important in the experimental determination of solubility, the efficiency of extractions, the rate of reactions and in general any heterogeneous process. Despite the extensive use of supercritical fluids, studies regarding the dissolution kinetics of compounds in supercritical carbon dioxide (scCO2) using analytical methods are limited in the literature.

I ZONEN - Framtida lärandemiljöer för yngre tonåringar i en urban kontext

Hur bör de senaste decenniernas utveckling inom IT och pedagogik påverka utformningen av nya lärandemiljöer? Kan skolarkitektur bidra till att främja god fysisk och psykisk hälsa? Arbetssätt och målsättningar har ändrats mycket inom den svenska skolan under de senaste decennierna. Informationsteknologi har i grunden ändrat tillgängligheten till information och påverkat hur vi både arbetar och koHow should the technological and pedagogical development during the last few decades affect the design of new schools? Can school architecture contribute to good physical and mental health in young teenagers? The way of working and targets for what the students should achieve have changed a lot in Sweden during the last few decades. Information technology has fundamentally changed the ease of ac

Effects of phosphorylation on oligomerisation and localisation of the Streptomyces coelicolor protein DivIVA in vitro

Streptomyces is the largest genus in the phylum Actinobacteria, known for their complex life cycle and secondary metabolite production. The model bacterium Streptomyces coelicolor grows _lamentously by tip extension and hyphal branching. The hyphal tip is highly organised, with various structural proteins forming a large assembly termed the polarisome. An essential protein, DivIVA, localises to th

Transpersoners förtroende för välfärdsinstitutioner

To what degree do transgender people trust welfare? This bachelor thesis aims to survey the trust in welfare institutions. Trust in institutions seems to affect to which extent people turn to and trust in welfare and will hence have consequences on individuals everyday- lives. Transgender people have, according to recent years Public Health Surveys, an inferior psychosocial position compared to th

Makten genom svenskämnet: en kritisk närläsning av styrdokumenten i svenska från 1962-2011

Denna uppsats undersöker styrdokumenten i svenska för grundskolans senare år, från 1962, 1980 och 2011. Uppsatsen skrivs i syfte att kritiskt kunna granska vad skolans och svenskämnets konstruktion är ett uttryck för, vad dess samhälleliga funktion har varit och är idag. För att synliggöra detta görs en studie där svenskämnet ställs i relation till de samtida och historiskt föregående ekonomiska o

Halmhus #1

Vårt examensarbete har handlat om att uppleva byggandet. Vi har helt själva, med enstaka hjälp av vänner och familj, och med begränsade ekonomiska medel, uppfört ett 20 kvm stort hus intill Arkitektskolan i Lund. Den centrala frågeställningen är: Hur är det att vara arkitekt och byggare samtidigt, och vad är speciellt med ett arkitektbyggt hus? Motiveringen till frågan är att utbildningen saknar Our master thesis project is about experiencing the act of building. We have all by ourselves, with occasional help from friends and family, and with limited economic resources, built a 20 m2 building besides Lund’s Architecture School. Our question formulation is: How is it to be the architect and the builder at the same time, and what is so special with a building built by an architect? We just

De faktorer som valts ut för studien är: headway, längd på blocksträckor, växelhastigeter och längd på sidospår. Arbetet inleds med en litteraturstudie där andra studier rö

Competitive Activism. An Investigation of the activists and volunteers in the 2015 refugee crisis.

I den här uppsatsen undersöks aktivisternas och volontärernas situation i deras arbete med flyktingarna under flyktingkrisen 2015 i Sverige. Genom att använda etnografiska metoder, i synnerhet kvalitativa intervjuer med individer engagerade i att hjälpa flyktingarna, argumenterar jag för att olika aktivistgrupper, trots att de har samma mål, uppvisar ett konkurrerande beteende. Genom en intersektiThis thesis investigates the situation of the activists and volunteers working with refugees in the context of the 2015 refugee crisis in Sweden. By employing ethnographic methods, especially qualitative interviews with the individuals engaged in helping the refugees, I argue that different activist groups having the same aim are exhibiting a competitive behavior. I illustrate that the role of ac
