Classical evolutionary life history concerns questions such as optimal timing of maturation, life span and number of offspring. These questions have mostly been studied theoretically under the assumption that the environment is stable and without taking into account frequency and density dependence. Life history theory is the basis for my thesis, in which I have studied the evolution of different
Popular Abstract in Swedish PAX FÖR MANETER! Evolutionen är den process som format det liv vi ser omkring oss. Ända sedan Darwins tid har man känt till att arter och djurgrupper uppstår genom att det finns en variation mellan individer och att då tillgångarna begränsas (såsom mat eller utrymme) blir det de bäst anpassade som överlever och fortplantar sig. Flercelliga djur har funnits på jorden i kDuring the course of evolution animal complexity and diversity is generated. The last couple of years it has become increasingly clear that morphologically diverse animals share a great deal of their genomic contents, and it must be the expression of regulatory genes in new setting, rather than the generation of new genes, that are fundamental for the generation of diversity. Basal phyla hold a ke
Popular Abstract in Swedish Mellan Rum. En studie i fysisk och mental utveckling av kommunikation med utgångspunkt i en mellanstadieklass. Avhandlingens första syfte är att beskriva den roll som kropp, känslor och rörelse spelar i skolans vardag. Här ingår såväl fysiska som verbalt språkliga rörelser. Teoretiskt vilar de analyser som förekommer i första hand på den franske fenomenologen Maurice MA Gap: A study in physical and mental development of communication based on a primary school class The primary aim of the dissertation is to describe the role played by body, emotions, and movement in the everyday life of school. This includes both physical and verbal linguistic movements. In theoretical terms the analyses are mainly based on the French phenomenologist Maurice Merleau-Ponty’s ide
Multi-step ahead response time prediction of CPU constrained computing systems is vital for admission control, overload protection and optimization of resource allocation in these systems. CPU constrained computing systems such as web servers can be modeled as single server queuing systems. These systems are stochastic and nonlinear. Thus, a well-designed nonlinear prediction scheme would be able
In Gebel el Silsila the quarry faces are cluttered with literally thousands of pictorial and textual representations; together they form a window of information to the ancient activity in the area and provide us with a prosopography of its workers and an idea of the ancients’ contemporary ideology. The more complex category of representations is quarry marks, a form of graffiti that appears in abu
Eukaryotic protein kinases, containing a conserved catalytic domain, represent one of the largest superfamilies of the eukaryotic proteins and play distinct roles in cell signaling and diseases. Near completion of rat genome sequencing project enables the evaluation of a near complete set of rat protein kinases. Publicly accessible genetic sequence databases were searched for rat protein kinases,
The infrastructure for natural gas distribution can provide the possibility of an evolutionary as opposed to revolutionary introduction of hydrogen as an additive to natural gas (Hythane). In this study, pure natural gas and a hythane blend with 24.8% (vol.) hydrogen have been used to fuel a multi-cylinder heavy-duty natural gas engine.. Some comparisons with pure hydrogen operation are also prese
We demonstrate control of the electron number down to the last electron in tunable few-electron quantum dots defined in catalytically grown InAs nanowires. Using low temperature transport spectroscopy in the Coulomb blockade regime, we propose a method to directly determine the magnitude of the spin-orbit interaction in a two-electron artificial atom with strong spin-orbit coupling. Because of a l
The fire safety of a performance-based design is often evaluated using deterministic analysis. In deterministic analysis, a number of representative fire scenarios, the design fire scenarios, are described and analysed. A quantitative description of the assumed fire characteristics for each fire scenario must then be made. These assumed fire characteristics are referred to as the design fire, i.e.
