[EN] In the early 1990s, the former communist countries of central and eastern Europe suffered the collapse of the centralized economy after the fall of the Berlin Wall and the transition towards liberalization began. The failure of international socialism against democratic capitalism would lead to the end of the cold war and to the development of the globalized world. This artistic piece would be located in the time and space of the former Slovak Socialist Republic which in the early 2000s was called "The Tatra Tiger", a series of three site-specific concerts where the remains of the abandoned structures of...

[EN] Demand for water is expected to grow in line with global human population growth, but opportunities to augment supply are limited in many places due to resource limits and expected impacts of climate change. Hydro-economic models are often used to evaluate water resources management options, commonly with a goal of understanding how to maximise water use value and reduce conflicts among competing uses. The environment is now an important factor in decision making, which has resulted in its inclusion in hydro-economic models. We reviewed 95 studies applying hydro-economic models, and documented how the environment is represented in them and...

[EN] Helicobacter pylori isolation in fecal samples is a less invasive and more comfortable practice than those that require patient endoscopy, particularly in children. However, culture of this pathogen from stools is usually unsuccessful. Other techniques such as PCR or H. pylori Stool Antigen (HpSA) are used to detect the presence of H. pylori in feces; nevertheless, a positive result by using these techniques does not involve viability of the pathogen. Direct Viable Count combined with Fluorescent in situ Hybridization (DVC-FISH) technique has been successfully applied to detect viable H. pylori cells in highly contaminated environmental samples. To assess the...

[EN] Current climate change (CC) predictions for the Western Mediterranean show a significant increase in temperature, and a decrease in precipitations, with great variability depending on general circulation models (GCM) and downscaling approaches. This paper analyses how dynamic downscaling improves statistically based CC scenarios. The study area was the Jucar River Basin (JB), with results from ECHAM5 GCM, and a close time frame of 2010-2040 appropriated for decision-making. The dynamic downscaling was performed with the regional climate model (RCM) RegCM3. It was applied to a coarse grid over the Iberian Peninsula, and then to a finer grid over the JB....

[ES] El proceso de adaptación de la legislación forestal a los nuevos desarrollos sociales y
económicos ha ganado importancia desde el 1990, revisándose las leyes forestales en
prácticamente todos los países europeos y definiendo las responsabilidades de los
propietarios, los beneficiarios directos y las entidades públicas. La legislación forestal
moderna y las políticas públicas tratan un amplio rango de productos y servicios forestales, y
tienen que equilibrar los derechos y las obligaciones de los propietarios frente otros grupos de
usuarios y de la comunidad. Aproximadamente el 50% de los bosques en Europa Occidental
pertenecen a propietarios privados, menos del 30% de la superficie corresponde a bosques

[EN] Changes in land use within a catchment are among the causes of non-stationarity in the flood regime, as
they modify the upper soil physical structure and its runoff production capacity. This paper analyzes the
relation between the variation of the upper soil hydraulic properties due to changes in land use and its
effect on the magnitude of peak flows: (1) incorporating fractal scaling properties to relate the effect of
the static storage capacity (the sum of capillary water storage capacity in the root zone, canopy interception
and surface puddles) and the upper soil vertical saturated hydraulic conductivity on the flood
regime; (2) describing the effect...

[EN] The objective of this study was to evaluate the economic and environmental sustainability of a sub-
merged anaerobic membrane bioreactor (AnMBR) treating urban wastewater (UWW) and organic fraction of municipal solid waste (OFMSW) at ambient temperature in mild/hot climates. To this aim, power requirements, energy recovery from methane (biogas methane and methane dissolved in the effluent), consumption of reagents for membrane cleaning, and sludge handling (polyelectrolyte and energy consumption) and disposal (farmland, landfilling and incineration) were evaluated within different
operating scenarios. Results showed that, for the operating conditions considered in this study, AnMBR technology is likely to be a net energy...

[EN] The present paper deals with a hydraulic jump study, characterization and numerical modeling.
Hydraulic jumps constitute a common phenomenon in the hydraulics of open channels that
increases the shear stress on streambeds, so promoting their erosion. A three-dimensional
computational fluid dynamics model is proposed to analyze hydraulic jumps in horizontal smooth
rectangular prismatic open-air channels (i.e., the so-called classical hydraulic jump). Turbulence is
modeled using three widely used Reynolds-averaged Navier Stokes (RANS) models, namely: Standard
k ε, RNG k ε, and SST k ω. The coexistence of two fluids and the definition of an interface
between them are treated using a volume method in Cartesian grids...

[EN] Droughts are a major threat to water resources systems management. Timely anticipation results crucial to defining strategies and measures to minimise their effects. Water managers make use of monitoring systems in order to characterise and assess drought risk by means of indices and indicators. However, there are few systems currently in operation that are capable of providing early warning with regard to the occurrence of a drought episode. This paper proposes a novel methodology to support and complement drought monitoring and early warning in regulated water resources systems. It is based in the combined use of two models, a...

[EN] There is ample recognition of the risk inherent in our very existence and modes
of social organization, with a reasonable expectation that implementing risk
governance will result in enhanced resilience as a society. Despite this, risk
governance is not a mainstream approach in the infrastructure sector, regardless
of the increasing number of peer-reviewed published conceptualizations, mature
procedures to support its application, or public calls to cope with systemic risks
in our modern societies. This paper aims to offer a different view on the issue of
risk governance, with focus in the analysis of the root causes of its relatively
low degree of implementation in the infrastructure sector....

[EN] Social impact assessment (SIA) has become a key factor for environmental conflicts
prevention, which makes necessary to integrate SIA and environmental conflict analysis (ECA). In this
article, we integrate SIA and ECA using a method based on grey systems and Shannon entropy. A case
study was conducted on a hydrocarbon exploration project located in the Sea of the Gulf of Valencia,
Spain. Four stakeholder groups and four evaluation criteria were identified. The results revealed that for
group of specialists the project would have negative social impact; and contrary perceptions were found
between the group ofprimary activities populationand the group of retirees. It was also noted...

[EN] We discuss the importance and meaning of a surface or material means with regard to interpretations and artistic strategies used nowadays. Since the emergence and development increasingly operative and efficient for digital imaging systems, there are, in parallel, a large and significant range of investigations of material resources, for the update is made by a certain materiality. We note then, that artistic practices are always in contact with a material medium, whether for image views is for experiments in modes of production and symbolic choices, expressive, interpretative or even adjustments to non-art systems

[EN] Photography, like any system of representation, creates a reality mediated by the subjectivity of its maker. With similar attitude to the adopted by the painter, facing the white canvas, the photographer adjusts the framework in order to fits this portion of reality that interests you to capture. Similarly, the journalist's eye, the editor's hand or the publishers' criteria are responsible for the construction of the media image and the discourse generated around it, traced and conveyed through its foundational ideological framework. If we assume that truth is generated like any other consumption product, any information transmited by the mass...

[EN] BACKGROUND: Oregano essential oil (EO) was incorporated into film-forming dispersions (FFDs) based on biopolymers (chitosan and/or methylcellulose) at two different concentrations. The effect of the application of the FFDs was evaluated on tomato plants (cultivar Micro-Tom) at three different stages of development, and on pre-harvest and postharvest applications on tomato fruit.
RESULTS: The application of the FFDs at '3 Leaves' stage caused phytotoxic problems, whichwere lethal when the EO was applied without biopolymers. Even though plant growth and development were delayed, the total biomass and the crop yield were not affected by biopolymer-EO treatments. When the FFDs were applied...

[EN] Chitosan films containing different concentrations of bergamot oil (BO) were obtained and the migration of limonene, the major oil component, to five liquid food simulants (aqueous solutions with 0%, 10%, 50% and 95% of ethanol and isooctane) was studied at 20 degrees C. The losses of BO and limonene during the film drying were also quantified. The release kinetics of limonene from chitosan matrix was described using an empirical model which relates the reduced concentration loss of limonene and the square root of time. The results show that kinetic constants for all films increased exponentially when the ethanol concentration...

[EN] The behavior of three different microalgal cultures, when exposed for a long period (>48 h) to dark conditions, was studied with a methodology based on respirometry. The cultures were transferred to darkness and the oxygen evolution in the reactors was monitored after successive air injections. Several sequential oxygen uptake rates were thus calculated and a respiration constant, assuming a first order decay of a fraction of the biomass, was obtained by calibration. Initial specific oxygen uptake rates were in the range of 0.9 5.1 mg O2 g TSS−1 h−1 and dark respiration constants in the range of 0.005 0.018...

[EN] Breeding through genetic transformation offers the possibility to add or modify single traits in cultivars without changing desirable characteristics. In grapevine this technology has been scarcely used, taking into account the economic importance of this crop. Up to now, the breeding of grapevine through genetic transformation has been mainly focused on biotic stress resistance, mainly to fungi and viruses. Among the factors that can explain the limited reports of success are the difficulty in regenerating transgenic plants, the availability of only a few characterized genes, and/or the quantitative character of the trait. Another influencing factor is the negative perception...

[EN] The effect of the encapsulation of eugenol and cinnamon leaf essential oil (CLEO) in lecithin liposomes on the losses of these
compounds during the chitosan film formation process by casting was evaluated. Film-forming dispersions and films with
eugenol or CLEO (either free or encapsulated) were obtained and characterized. The content of eugenol in active films was
quantified by means of solvent extraction and gas chromatograph analysis. The encapsulation of eugenol or CLEO in lecithin
liposomes led to the films retaining 40% −50% of the incorporated eugenol, whereas only 1%−2% was retained when
eugenol was incorporated by direct emulsification. Films with liposomes exhibited a lamellar...
