The i-motif is a DNA structure formed by cytosine-rich sequences that consists of parallel- stranded duplexes held together by intercalated base pairs. The in vitro formation of this structure in DNA sequences corresponding ...
Chemometric methods have been used to explore and analyze information regarding potable and waste water quality in this Thesis. The analyzed data were obtained from (a) drinking water disinfection processes, (b) wastewater ...
This Thesis deals with the resolution of hyperspectral imaging data by using chemometric methods, in particular by using appropriate data pretreatment methods and by using Multivariate Curve Resolution (MCR) methods. The ...
Despite their small size, phytoplankton represents up to 50% of the global primary production of the Earth and serves as a connector between oceanic and atmospheric processes. Therefore, phytoplankton constitutes a central ...
The study of the 3D structural details of protein interactions is essential to understand biomolecular functions at the molecular level. In this context, the limited availability of experimental structures of protein-protein ...

This thesis deals with three possible applications of stochastic calculus: modelling prices by supply and demand in a financial market where there is an informed trader, turbulence and financial models using ambit processes ...
The study of supersymmetry has led us to a better understanding of field theories, specially in the strong coupling regime. In this thesis we have tried to show this through several examples. These are: - The first of ...
The current world population is over 7.4 billion and expected to exceed 9 billion in 2040, causing a 70% increase in food demand. Global environmental degradation, in the form of salinization, pollution and global warming, ...
The sequence of chapters can be divided into three blocks. - The first block contains the introductory chapters. In chapter 1 we illustrate the problem of the high-Tc superconductors making a parallelism between the ...
This work is at the crossroads where conservation problems, arising from the biodiversity loss and environmental crisis, meet the difficulties of applying research outcomes in conservation practice, framed in a sustained ...
