Branch Identification in Elastic Stability Analysis

Popular Abstract in Swedish Avhandlingen behandlar metoder för att kunna beräkna den last en struktur kan bära. En struktur kan i detta sammanhang vara allt från en bro till en mjölkkartong. För att kunna göra en korrekt bedömning av den lastbärande förmågan måste hänsyn tas till olinjära effekter som härrör från stora deformationer. Sådana olinjära effekter kan orsaka instabilt beteende hos en stIn this thesis, methods to determine the static postbuckling behaviour of elastic structures undergoing large deformations, are considered and developed. Since the governing non-linear equations usually becomes too complex to be handled analytically, the main focus has been on developing methods that can be incorporated into a numerical solution scheme, such as the finite element method. First me

Macrocyclic Carbohydrate/Amino Acid Hybrid Molecules - Synthesis and Evaluation as Artificial Receptors

Methods were developed for the synthesis of three different types of macrocyclic carbohydrate/amino acid hybrid molecules. In the synthesis of the first type of macrocycles, a glucosamine derivative was oxidized at C6 and the obtained sugar amino acid was coupled to tripeptides. The resulting hybrids were transformed into dimers and cyclized in a macrolactamization step to obtain C2-symmetric macr

INOSITOL PHOSPHOLIPID-BASED SIGNAL TRANSDUCTION IN PLANTS Phosphoinositide-Specific Phospholipase C and 3-Phosphoinositide Dependent Protein Kinase-1 in Arabidopsis thaliana

Popular Abstract in Swedish Alla levande organismer måste kunna anpassa sig till förändringar i sin omgivning, såsom kyla, värme eller torka. Vid sådana förändringar tar enskilda celler emot signaler ifrån sin omgivning via särskilda s.k. receptorproteiner på cellytan. Receptorproteinerna skickar signalerna vidare in i cellen, där de kan ge upphov till en kedja av processer, vilka slutligen leder Phosphoinositides (PIs) play major roles in cell signal transduction. Although it is clear that PIs are important components also in plant signalling, little is known about their roles in plant cells, compared to animal cells. This thesis describes work on two PI-dependent enzymes involved in plant intracellular signalling, phosphoinositide-specific phospholipase C (PI-PLC) and 3-phosphoinositide

Limit properties of the monotone rearrangement for density and regression function estimation

The monotone rearrrangement algorithm was introduced by Hardy, Littlewood and Po ́lya as a sorting device for functions. As- suming that x is a monotone function and that an estimate xn of x is given, consider the monotone rearrangement xˆn of xn. This new estimator is shown to be uniformly consistent. Under suitable as- sumptions, pointwise limit distribution results for xˆn are obtained. The fra

The linguistic encoding of placement and removal events in Jahai

This paper explores the linguistic encoding of placement and removal events in Jahai (Austroasiatic, Malay Peninsula) on the basis of descriptions from a video elicitation task. It outlines the structural characteristics of the descriptions and isolates semantically a set of situation types that find expression in lexical opposites: (1) putting/taking, (2) inserting/extracting, (3) dressing/undres
