La consagración de los derechos fundamentales: de principios generales a texto fundacional de la Unión Europea
2014
<p>El autor argumenta que el reconocimiento formal de los derechos fundamentales como parte de los fundamentos comunes de la UE mediante la remisión a la Carta de los Derechos Fundamentales en el Tratado de Lisboa (otorgándole carácter vinculante y, por ende, elevando su rango y confiriéndole el mismo valor jurídico que los Tratados) ha proporcionado una mayor apariencia constitucional a la UE, pero no un nivel más generoso de protección y de disfrute de la ciudadanía. En efecto, además de haber prescindido de garantías específicas, la Carta de la UE ha introducido diversas asimetrías inaceptables, tales como la quiebra del principio de indivisibilidad (los derechos civiles y los soci…
Functional bread supplemented with Pleurotus eryngii powder: A potential new food for human health
2022
The purpose of this study was to develop functional breads with powdered Pleurotus eryngii. The breads were produced applying the traditional Italian style sourdough technology. P. eryngii powder was added to flour of tender wheat varieties (Grano Dei Miracoli, Inalettabile, Mentana, Gentilrosso, Ardito and a mix of Rieti, Verna, and Mentana) or semolina of durum wheat landrace (Saragolla) and subjected to sourdough fermentation. Sourdough inoculum was produced with selected strains of lactic acid bacteria (LAB) belonging to the species Levilactobacillus brevis, Weissella cibaria and Leuconostoc citreum. The addition of Pleurotus powdered (PP) (10% w/w) did not influence the fermentation pr…
PLANT EXTRACTS AS GREEN POTENTIAL STRATEGIES TO CONTROL THE BIODETERIORATION OF CULTURAL HERITAGE
2016
The biodeterioration of historic-artistic manufacts is related to several biological systems, including fungi and bacteria, whose metabolic activities and vegetative development have a direct consequence on the conservation of cultural assets. Generally, different chemical compounds are utilized as biocides in order to control biodeteriogens growth, but recently the attention has been focused on potential risks of their use towards human health (operators, visitors) and the environment. In order to develop alternative methods, various natural products have been tested, particularly to control the colonization by fungi and bacteria. In this study, antimicrobial activity of three different pl…
: Looking through the gaps of the digital divide in Higher education
2007
A partir de una muestra de 719 estudiantes de la Universidad de Chile en 2004, este artículo analiza las diferencias existentes respecto de capitales culturales materiales e incorporados relacionados con el acceso y uso de las nuevas tecnologías de la información y comunicación (NTICs). Bajo diferentes métodos de análisis cuantitativo se pone de manifiesto la existencia de niveles de brecha digital para tales herramientas, brecha que estaría relacionada especialmente al género pero también a la condición socioeconómica. Esta última variable, aunque presente, muestra efectos más bien indirectos no pareciendo influir en las actitudes y disposiciones de los estudiantes respecto al uso de las N…
Biotechnology and Cultural Heritage Conservation
2020
The deterioration of cultural asset is induced by biological, chemical, and physical factors, influenced by anthropogenic activity and environmental conditions. In this study, the contribution of biotechnology is emphasized to define the conservation strategy, for a marble Fountain (Two Dragons, XV century) located in Palermo city center, based on an integrated approach and eco-friendly procedures. Biotechnological protocols are preliminarily applied as an integrated approach, based on microscopy observation, in vitro culture and genomic DNA analysis to recognize and characterize microbial communities. Several biological systems have been identified: green algae (Chlorella) and cyanobacteri…
Multi-criterial approaches for the inventory and the evaluation of traditional cultural landscapes
2008
The Mediterranean environment is characterized by an high variability in ecological features and by a rich biodiversity, whose interaction has generated complex agro-forestry systems. The resulting cultural landscapes can represent a remarkable trait of Italian landscape. Nonetheless, since several decades they are at risk mainly owing to the consequences of cultural intensification, that has turn out in new cultural models, i.e. specialized high density agronomic plantation, or in a progressive abandonment of agricultural land. In order to prevent the degradation or loos of these particular ecosystems, it becomes a priority to adopt measures for their preservation and promotion. Regardless…
The importance of terracing in the traditional cultural landscapes: the case study of Sicily (Italy)
2012
The landscapes formed by agricultural terraces are the natural result of the encounter between the characteristics of an environment and the creative force and genius of man, the slow evolution of this relationship between nature and culture, a collective project that balanced the need for producing with the resources available and the native character of the environment. These cultural processes produced a great variety of landscapes. However, they are not supported or confirmed by common inventories allowing to identify and classify the typical Main Traditional Landscape (MTL) within which very important is the role carried out by terraces and related man-made structures, both for natural…
Ecosystem services provided by marine and freshwater phytoplankton
2021
AbstractPhytoplankton, the ecological group of microalgae adapted to live in apparent suspension in water masses, is much more than an ecosystem’s engineer. In this opinion paper, we use our experience as phytoplankton ecologists to list and highlight the services provided by phytoplankton, trying to demonstrate how their activity is fundamental to regulate and sustain Life on our Planet. Although the number of services produced by phytoplankton can be considered less numerous than that produced by other photosynthetic organisms, the ubiquity of this group of organisms, and their thriving across oceanic ecosystems make it one of the biological engines moving our biosphere. Supporting servic…
Intracellular pH-dependent efflux of the fluorescent probe pyranine in the yeast Yarrowia lipolytica.
2001
International audience; 8-Hydroxypyrene-1,3,6-trisulfonic acid (pyranine) can be used as a vital intracellular pH (pH(i)) indicator. In the yeast Yarrowia lipolytica, a partial efflux of the probe was detected by using the pH-independent wavelength of 415 nm. A simplified correction of the fluorescent signals was applied, enabling to show for this species a good near-neutral pH(i) maintenance capacity in a pH 3.9 medium. Octanoic acid, which is known to have toxic effects on yeast, decreased the pH(i) and increased the 260-nm-absorbing compounds leakage. However, this acid inhibited the fluorescent probe efflux linearly with its concentration suggesting a pH(i)-dependent efflux of pyranine …
- CREDIT RISK AND EFFICIENCY IN THE EUROPEAN BANKING SYSTEMS: A THREE-STAGE ANALYSIS
1999
Increased competition and the attempts of European banks to increase their presence in other markets may have affected the efficiency and credit risk. The first of this aspects is based on the incentive to the banks to reduce cost in order to gain in competitiveness. The second is associated to their lack of knowledge of such markets and/or acceptance of a higher risk in order to increase their market share. Despite the importance of these aspects, banking literature has usually analyzed the effects of competition on the efficiency of banking systems without considering these aspects. The few studies that attempt to obtainrisk adjusted efficiency measures do not consider that part of the ri…
