Popular Abstract in Swedish Att förstå mekanismen som bestämmer djurs beteende är inte lätt. Genom att studera beteendet hos enklare djur kan man göra det mer förståeligt. Om man vill studera ljusstyrt beteende är det enklaste djuret att använda en manet från karibiska området vid namn Tripedalia cystophora. Denna manet har ögon som liknar människans ögon. De lever i vattnet i mangroveskogar och äMost animals use eyes to guide their behaviour. Analysing, and understanding, visually guided behaviours gets more complicated the more advanced the animal gets. Box jellyfish provide a relatively simple system for understanding visually guided behaviours. They have a limited nervous system, but they also possess a visual system that is quite impressive for a jellyfish. Box jellyfish have 24 eyes

The essay examines how contemporary artists directly or indirectly violate laws not only in order to create art, but also to break into—and become recognised by—the artworld. It first discusses two much-debated Swedish artworks—Lars Norén’s play Seven Three (1998) and Anna Odell’s Unknown, woman 2009-349701 (2009)—that have brought about confrontations between individuals and social institutions.

Popular Abstract in Swedish Att kunna lokalisera och bedöma en partner är en av de, evolutionärt sett, viktigaste egenskaperna hos alla sexuellt reproducerande organismer. För att möjliggöra detta använder sig ett djur sig av olika (visuella, taktila, akustiska och kemiska) signaler för inomartskommunikation. Jag har genom att studera kemiska signaler för inomartskommunikation (s.k. feromoner) hoLocating and evaluating a suitable partner for mating is one of the most important events in any sexually reproducing organism. To achieve this, an animal must be able to locate its partner over both long and short distances, and finally evoke the proper mating behaviour. This is made possible by use of conspecific signals picked up by one or several sensory systems, the most well investigated bei

Popular Abstract in English The sesquiterpene lactones is an important group of natural products, and they are present in many medicinal plants. Their most important biological activities are anti-inflammatory and anti-cancer activity, although for many decades their potential use as drugs was dismissed. The main reason for this was their alkylating capacity, reacting with thiol functions in proteDamsin (1) is a natural sesquiterpene lactone (SL) isolated from Ambrosia arborescens Mill., a plant used in the Andes as antiinflammatory medicine. This natural product is an inhibitor of NF- κB, a protein complex that controls the transcription of many genes in mammalian cells, and has a potential for standing model for the development of new anti-cancer lead structures. In order to improve the

Whilst Building Information Modelling (BIM) promises significant improvements in construction quality and efficiency, current contractual models do not encourage its use; indeed actively inhibit the collaboration at its core. To help bring BIM into the mainstream, it is claimed we need to re-craft existing contractual relationships to facilitate collaborative decision making and to equitably alloc

The Global Energy Assessment (GEA) brings together over 300 international researchers to provide an independent, scientifically based, integrated and policy-relevant analysis of current and emerging energy issues and options. It has been peer-reviewed anonymously by an additional 200 international experts. The GEA assesses the major global challenges for sustainable development and their linkages
