PhD thesis A big challenge in Plant Biotechnology – both for the scientific community and the industry – is to develop strategies that allow the removal of selectable marker genes and the introduction of targeted modifications in genomic sequences (gene targeting). In this manuscript such strategies, based on the activation of a recombinase in the germline of Arabidopsis thaliana, are described...

A proper understanding of reservoir fluid phase behavior is the first crucial step in the development and production of an oil/gas field. This paper addresses the challenges and errors associated with the fluid sampling that may arise before, during and after the sampling operation. For this aim, DST and PVT data of exploration and production wells of a supergiant offshore gas condensate reserv...

Urban infrastructure will require transformative changes to adapt changing disturbance patterns. We ask what new opportunities hybrid infrastructure—built environments coupled with landscape-scale biophysical structures and processes—offer for building different layers of resilience critical dealing increased variation in the frequency, magnitude phases climate-related disturbances. With its mo...
