The role of natural biofilms affecting the water quality in rivers has been the main theme in this study. Firstly, the study developed the capacity of biofilms in retention and/or production of DOC. Secondly, the study ...
[eng] The emergence and spread of antibiotic resistance among bacteria has become an undisputed global problem and one of the greatest threats to public health in the 21st century. The widespread, excessive and uncontrolled ...
Studies of mountain belts worldwide show that along-strike changes are common in their foreland fold-and-thrust belts. These are typically caused by processes related to fault reactivation and/or fault focusing along changes ...
Gamma-ray binaries are extreme systems that produce non-thermal emission from radio to very-high-energy (above TeV) gamma rays, with the energy output in the spectral energy distribution (SED) dominated by the MeV–GeV ...
The main objective of this Ph. D. Thesis work was to study the physicochemical properties of the inner membrane of mitochondria and the interaction of "cyt c" with model membranes. Suitable techniques were used to accomplish ...
In a time when large amounts of data about social, economical, technological, and biological systems are produced in a daily bases, complex networks have become a powerful tool to represent the structure of complex systems. ...
In this report novel materials for advanced applications are studied by means of the latest microscopy technologies and methodologies which have had a dramatic impact on progress of materials science. The aim was to study ...
The thesis research concerned evolutionary ecology and community ecology of amphibians in two different areas of a Mediterranean region. The goal of the research was to test how anuran species coexist along a lentic ...
The study of chromatin structure in several simple sperm models of increasing complexity was performed. Species demonstrating different types of sperm nuclear protein transitions and structural changes in spermatic chromatin ...
From the fundamental point of view, NPs formed by MFe2O4 with (M= Co, Fe) are ideal system models to study the new magnetic phenomena associated with the so-called particle-like behaviour, which emerges from the size ...
The common scope of this thesis is the application of structural biology and biophysics to obtain novel data on nuclear proteins that modulate DNA transcription. The proper regulation and functioning of these elements are ...
Prostate cancer (PCa) is the second most common cancer in men after lung cancer. Around 1.1 million men worldwide were diagnosed with PCa in 2012. PCa depends essentially on androgen stimulation for growth and cell survival. ...
Viruses are submicroscopic biological entities that need to infect a host cell in order to replicate. In their simplest form viruses are constituted by an infective genetic material and a protein shell (the capsid) that ...
Molt is the process of plumage renewal by which birds maintain and adjust its functionality throughout their lifecycle. Multiple elements have been tackled in bird molt research (timing, duration, sequence, intensity, ...
The herpesvirus diseases are increasing in importance as a public health problem throughout the world. Members of the human herpesvirus family are global in distribution and infect 60-95% of the world's population, both ...
[eng] The question of whether automation will cause mass unemployment has been a pressing concern in recent years. While estimates on the number of automatable occupations vary, the prospect of a substantial share of jobs ...
Bajo el titulo "Studia Iuuenciana" se agrupan un conjunto de trabajos de carácter léxico -volúmenes segundo y tercero respectivamente- y un estudio de la imitación que de Virgilio lleva a cabo el poeta Vecio Aquilino Juvenco ...
La presente tesis comienza con una semblanza histórica de la figura de Lucifer de Cagliari, basada en testimonios contemporáneos o poco posteriores y en los reflejados en sus propias obras. A continuación se realiza una ...
DE LA TESIS:<br/><br/>Bajo el título de "Studia Nigidiana" queda recogido un trabajo de estructura unitaria dividido en cuatro partes que tienen un valor independiente entre sí pero que están unidas por un conjunto de ...
El estudio de la tradición de Estacio, y concretamente de la "Tebaida", no se habla abordado en España hasta ahora de una manera sistemática. Marcelino Menéndez y Pelayo reunió a fines del siglo pasado los pocos conocimientos ...
