Staged Evolution
Architecture has the power to reveal the complexities of man in nature through the degree of control in the process of form making. This process offers the opportunity to create different physical and psychological experiences dependent on its articulation. This is a study that explores the …

Evolution Semigroups for Well-Posed, Non-Autonomous Evolution Families
… is called a global flow if it describes the time evolution of a system with the initial state x \in \Omega at time t \geq s \geq 0. Koopman's approach to the study of flows is to look at the dynamics of the observables of the states instead of studying the dynamics of the states directly. To do …

Evolution of the genus Aristolochia - Systematics, Molecular Evolution and Ecology
Evolution of Piperales – matK gene and trnK intron sequence data reveal lineage specific resolution contrast. Piperales are one of the largest basal angiosperm orders with a nearly worldwide distribution. The order includes three species rich genera, Piper (ca. 1,000 species), Peperomia (ca. …

Evolution And Ethics
<p>Does evolution inform the ancient debate about the roles that instinct (emotion/passion/sentiment/feeling) and reason do and/or should play in how we decide what to do? Evolutionary ethicists typically adopt Darwinism as a suitable explanation for evolution, and on that basis draw conclusions …

Evolution of syngamy
… have probably persisted since early eukaryotic evolution. I discuss the purpose of sex without genetic mixing and proffer that sex is a conservative mechanism that decreases heritable genetic variation. Syngamy (nuclear/pronuclear fusion/association + "mixing" of chromosomes) is a …

Supply Chain Network Evolution: Demand-based Drivers of Interfirm Governance Evolution
… model of supply chain network governance evolution that attempts to link environmental, network, production, firm and exchange factors in a continuously evolving loop. The proposed framework expands transaction cost analysis' explanatory power. Results partially support past scholarly …

Testing the Major Theories Concerning the Evolution of Sex using Experimental Evolution
The evolution of sexual reproduction has been dubbed "the queen of problems in evolutionary biology". While there is a large amount of theory about the evolution of sex, there is relatively little well controlled empirical data. This thesis is an attempt to use an experimental evolution based …

Evolution of the African Tigerfish (Genus Hydrocynus) : phylogeographic insights into drainage evolution
… fish, can reveal details of drainage evolution, especially where their evolutionary relationships can be reconstructed using phylogeographic methods. In this study, the mitochondrial DNA sequence diversity of the characiform genus, Hydrocynus, which is widespread across tropical …

Molecular Evolution of Viruses
<p>Molecular evolution is the process of evolution at the scale of DNA, RNA and proteins. Our goal was to study molecular evolution of viruses with special reference to Influenza A Virus.</p> <p>The recent Influenza A/H1N1(2009) outbreak has been the focus of intense research because of its high …

Evolution des programmierten Zelltods
The simple metazoan Hydra does posses two genes for caspases: Caspase 3A and caspase 3B. We generated antibodies against these caspases. By immunofluorescence staining and cell fractionation we demonstrated that both caspases are localized in mitochondria in vivo.Caspase 3A is a constitutively …

The evolution of honeycomb
… of wasps and bees. Here my thesis focuses on the evolution of honeycomb in two chapters: (1) a test of mechanical properties of honeycomb across nests that vary in cell-size and material, and (2) an assessment of the origin of honeycomb nests in wasps and bees using recently published phylogenies. …

The Evolution of Cryptology
<p>We live in an age when our most private information is becoming exceedingly difficult to keep private. Cryptology allows for the creation of encryptive barriers that protect this information. Though the information is protected, it is not entirely inaccessible. A recipient may be able to access …

Thermal Evolution of Moon
… to get a novel insight into the thermal evolution of the Moon over a complete lunar cycle. Half a lunar cycle would account from morning to night and lasts for approximately 14.75 days. Seeing how the pixel value changes from morning to night the pixel and temperature trends can be …

Evolution of the Proteasome
Evolution of the proteasome multigene family was examined across all domains of life using experimental and computational techniques. First, degenerate primers designed to universally amplify all alpha proteasomes were used in the polymerase chain reaction with genomic DNA to probe the diversity of …
