Vertebrate sex ratios are notorious for their lack of fit to theoretical models, both with respect to the direction and the magnitude of the sex ratio adjustment. The reasons for this are likely to be linked to simpilfying assumptions regarding vertebrate life histories. More specifically, if the sex ratio adjustment itself influences offspring fitness, due to sex-specific interactions among offsp

Somatoform disorders are more common than many clinicians realize and are often underdiagnosed and poorly managed. This practical guide provides a comprehensive overview of all somatoform disorders. It aims to enable the mental health practitioner to properly diagnose and manage the disorders as well as to provide the appropriate advice to colleagues of other medical disciplines. Somatoform Diso

Popular Abstract in Swedish Att en elektrisk urladdning ger upphov till ljus syns varje gång blixten slår ner. Den omvända processen, att ljus kan skapa en elektrisk urladdning, upptäcktes av Hertz 1887 som en parentes i utvecklingen av radiomottagare. Undersökningar av detta fenomen visade att elektroner bara kunde frigöras av ljus som hade tillräckligt hög frekvens (ultraviolett). Förklaringen aTreating the correlated behaviour of multiple particles is challenging for both theory and experiment. This thesis reports on a variety of experimental investigations aiming to advance the understanding of fundamental processes in atoms and molecules: double ionization, isomerization and dissociation. The emphasis lies on ultra-fast processes, where multiple electrons interact or nuclei move so ra

Popular Abstract in Swedish Fram till början av 80-talet var det främsta sättet, för att ta fram ett material med en ny egenskapsprofil, att framställa en ny polymer. Att ta fram denna polymer tog både lång tid och stora kostnader i anspråk. Utvecklingen gick i stället mot att blanda redan kända polymerer och på så sätt kombinera deras individuella egenskaper. De flesta polymerer är inte blandbaraThe search for polymeric materials with new property profiles has stimulated a great interest into polymer blends and reactive processing. During recent years many new blends have reached the market. Although some of these are homogeneous mixtures of polymers, most commercial blends are composed of immiscible polymers, and contain two or more polymeric phases. The properties of such blends depend

This paper deals with the problem of reconstructing the locations of a number of points in space from three different images taken by uncalibrated cameras. It is assumed that the correspondences between the points in the different images are known. In the case of six points this paper shows that there are in general three solutions to the problem of determining the shape of the object, but some of

In this research project public library Facebook use is explored and analyzed in relation to Henry Jenkin’s work on participatory cultures and literacy.

Popular Abstract in Danish Omkring halvdelen af den globale kulstof mængde som findes i jorden, er lagret i de arktiske jorde. Arktiske jorde har været anset for at være vigtige kulstof reservoirs de sidste 10.000 år, hvor der bliver optaget mere kulstof end der frigives. Dette skyldes blandt andet den langsomme omsætning af organiske materiale på grund af de kolde forhold, men også de store mængdArctic ecosystems hold massive amounts of the global carbon in their soils and are of great importance for the global terrestrial exchange of greenhouse gases to the atmosphere. The arctic region has in general been acting as a C sink for the past 10000 years, however with climate change the C balance in some areas is shifting towards becoming a C source. Herbivory are an important part of many ec

Detta informationsblad syftar till att förmedla resultat som kan vara av betydelse för kommuners och andra aktörers användning av GIS i kris. Innehållet bygger på intervjuer med tjänstemän från tre kommuner och en länsstyrelse som har erfarenheter av tillämpningar av GIS i samband med stormen Gudrun. Det är således en sammanfattning av den kunskap som redan finns hos många kommuner och som är värd

In this paper we suggest an improvement to a recent algorithm for estimating the pose and ego-motion of a camera which is constrained to planar motion at a constant height above the floor, with a constant tilt. Such motion is common in robotics applications where a camera is mounted onto a mobile platform and directed towards the floor. Due to the planar nature of the scene, images taken with such
