Popular Abstract in Swedish Alla levande celler omges av membran, som reglerar dess kontakt med omgivningen. Cellmembran består av flera sorters lipider men även av kolhydrater och ett stort antal proteiner med olika funktion. Lipider är en grupp av molekyler som har ett hydrofilt (vattenälskande) huvud och en hydrofob (vattenavstötande) svans. I en omgivning lik den i kroppens celler d.v.s. beståThe work presented in the thesis “RNA in model lipid membranes- interactions in bulk and at surfaces” aims to characterize the interaction between RNA and model membranes with different properties as well as to determine if ssRNA associate with model membranes in different ways. Several techniques have been used to characterize these systems, including quartz crystal microbalance with dissipation

High-throughput technologies have led to an explosion in the availability of data at the genome scale. Such data provide important information about cellular processes and causes of human diseases, as well as for drug discovery. Deciphering the biologically relevant results from these data requires comprehensive analytical methods. In this dissertation, we present methods for gene and protein expr

Popular Abstract in Swedish HIMMELSKOMPASSEN En orienterare förlitar sig på karta och kompass för att finna sin väg genom skogen. När solen börjar gå ner blir det allt svårare att urskilja den röda kompassnålens riktning och detaljerna på kartan. Orienteraren slår slutligen på sin pannlampa och fortsätter springa mot sitt mål. Han är inte ensam. Många andra varelser har också ett mål att nå under The polarization pattern of skylight offers many animals a reference for visual compass orientation. In those cases when this optical compass is identified, the receptors involved are often confined to a small part of an eye built predominantly for other visual tasks. This thesis reports the discovery of a unique compass organ in the spider Drassodes cupreus, where a pair of specialised secondary

Abstract in UndeterminedFor centuries rammed earth has been a method of construction in various parts of the world. It is an economical building technique as earth is an abundant cheap resource. It is durable, safe and a desirable building technique for hot climates. This paper is discussing a workshop activity in building with sustainable rammed earth construction methods in Egypt. It adds to pre

Abstract— Context: Software product lines (SPL) are used in industry to achieve more efficient software development. To test a SPL is complex and costly and often becomes a bottleneck in the product line organization. Objective: This research aims to develop and evaluate strategies for improving system test selection in a SPL. Method: Initially industrial practices and research in both SPL testing

The knife-edge technique for measurements of micrometer-sized beams is extended to two-dimensional imaging by tomographic reconstruction of multiangular knife-edge data. Two-dimensional intensity distributions at optical (633-nm) and soft-x-ray (13.5-nm) wavelengths at the focal region of a Schwarzschild objective are presented. The resolution is limited by the 200-nm step size used in the data ac

Inference to the best explanation (IBE) is theoretically interesting in that it promises to throw new light on what an explanation is. IBE challenges the standard view of the relation between inference and explanation. But sometimes it seems that previous explanation is more independent of inference than IBE suggests. Sometimes we have explanation before inference (EBI) which is not IBE. This chap

Popular Abstract in Swedish Enzymet magnesium-kelatas katalyserar bildandet av magnesium-protoporfyrin genom insättning av en magnesiumjon i protoporfyrin. Detta är det första unika steget i tillverkningen av klorofyll hos växter, alger och fotosyntetiska bakterier. Magnesium-kelatas består av tre proteiner som kallas I (vikt 40 kDa), D (70 kDa) och H (140 kDa). Det är viktigt att bestämma dessa pThe enzyme magnesium chelatase inserts magnesium into protoporphyrin IX (Proto) to produce to magnesium protoporphyrin IX, the first unique intermediate of the chlorophyll biosynthetic pathway. Magnesium chelatase is composed of three distinct proteins termed I (molecular weight ~40 kDa), D (~70 kDa) and H (~140 kDa). Defining the individual properties and structure of the magnesium chelatase comp
