Venezuela's humanitarian crisis, resurgence of vector-borne diseases, and implications for spillover in the region
2019
In the past 5–10 years, Venezuela has faced a severe economic crisis, precipitated by political instability and declining oil revenue. Public health provision has been affected particularly. In this Review, we assess the impact of Venezuela's health-care crisis on vector-borne diseases, and the spillover into neighbouring countries. Between 2000 and 2015, Venezuela witnessed a 359% increase in malaria cases, followed by a 71% increase in 2017 (411 586 cases) compared with 2016 (240 613). Neighbouring countries, such as Brazil, have reported an escalating trend of imported malaria cases from Venezuela, from 1538 in 2014 to 3129 in 2017. In Venezuela, active Chagas disease transmission has be…
The Effect of Different Light Intensities on the Frequency and Size of Stomata, the Size of Cells, the Number, Size and Chlorophyll Content of Chloro…
1980
Summary Plants of Sinapis alba were cultivated under high light (60 W m -2 PhAR) and low light (6 W m -2 PhAR) conditions. High light intensity during growth increased the stomatal frequency but there were only small changes in the length of the stomatal pore. High-light leaves had more than twice as many stomata per unit area as low-light leaves. The decrease of stomatal diffusive resistance in high-light leaves is primarily caused by the increase in stomatal density. There were striking changes in stomatal frequency during the ontogeny of primary leaves. High light caused a stronger development of the assimilating mesophyll. The volume of the palisade cells increased to a much higher exte…
The urban revitalization of the coastal tourist destinations: An alternative for the Valencian Mediterranean tourist municipalities
2021
espanolLos municipios del litoral mediterraneo valenciano aumentaron sensiblemente su superficie construida por la irrupcion de la actividad turistica a mediados del siglo XX. A pesar de las ventajas iniciales, los problemas surgidos sobre el espacio urbano, por la naturaleza del modelo de desarrollo turistico utilizado, los dirigen hacia una perdida progresiva de su atractivo turistico. Ante esta circunstancia, se hace necesario intervenir sobre el espacio urbano, no solo para renovar el destino turistico sino tambien para corregir los problemas urbanos generados durante las ultimas decadas en unos municipios que supeditaron sus decisiones exclusivamente a las necesidades turisticas. Una o…
The arithmetic decomposition of central Cantor sets
2018
Abstract Every central Cantor set of positive Lebesgue measure is the arithmetic sum of two central Cantor sets of Lebesgue measure zero. Under some mild condition this result can be strengthened by stating that the summands can be chosen to be C s regular if the initial set is of this class.
Discussion on “Experimental Deformation of Opalinus Clay at Elevated Temperature and Pressure Conditions: Mechanical Properties and the Influence of …
2021
AbstractThe testing procedure and results on saturated samples of Opalinus Clay in the work of Schuster et al. (Rock Mech Rock Eng https://doi.org/10.1007/s00603-021-02474-3, 2021) were conducted and presented using strain rates two to four orders of magnitudes higher than the rates needed to allow pore pressure equilibrium in the material, both in drained and undrained conditions. This leads to an erroneous estimation of the mechanical properties in saturated conditions. We discuss this aspect in the context of shale testing. We also discuss the effect of drying-induced fissuring on the mechanical properties of geomaterials tested in dry conditions.
Burrows-Wheeler transform and palindromic richness
2009
AbstractThe investigation of the extremal case of the Burrows–Wheeler transform leads to study the words w over an ordered alphabet A={a1,a2,…,ak}, with a1<a2<⋯<ak, such that bwt(w) is of the form aknkak−1nk−1⋯a2n2a1n1, for some non-negative integers n1,n2,…,nk. A characterization of these words in the case |A|=2 has been given in [Sabrina Mantaci, Antonio Restivo, Marinella Sciortino, Burrows-Wheeler transform and Sturmian words, Information Processing Letters 86 (2003) 241–246], where it is proved that they correspond to the powers of conjugates of standard words. The case |A|=3 has been settled in [Jamie Simpson, Simon J. Puglisi, Words with simple Burrows-Wheeler transforms, Electronic …

Disputas por el poder municipal y reforzamiento regio en el realengo valenciano. De la derrota agermanada a las cortes de 1604
2021
La introducción del procedimiento electoral de insaculación en buena parte de los municipios valencianos trató de justificarse por su virtualidad para erradicar o reducir la conflictividad generada por los tradicionales mecanismos de cooptación. Las disputas, sin embargo, no desaparecieron con el nuevo sistema y tuvieron oportunidad de expresarse en distintas fases de su aplicación. A partir del análisis de una amplia casuística se trata de mostrar las modalidades que adoptó, en el plano electoral, la pugna por el poder municipal en el marco de la insaculación durante el siglo xVI, así como su incidencia en el creciente fortalecimiento de los órganos y oficiales de la administración regia, …
One dimensional consolidation of Opalinus Clay from shallow depth
2017
First experimental results on Opalinus Clay from shallow depth (< 30 m depth) are presented and compared to results on cores from Mont Terri Underground Rock Laboratory (~ 300 m depth). Samples were tested in one dimensional condition using an advanced experimental technique. The samples from the two sites show similar properties in terms of geotechnical characterization and one dimensional compressibility/swelling indexes, despite the different source depths.
The impact of COVID-19 on alternative and local food systems and the potential for the sustainability transition: Insights from 13 countries
2021
The COVID-19 pandemic has been a major stress test for the agri-food system. While most research has analysed the impact of the pandemic on mainstream food systems, this article examines how alternative and local food systems (ALFS) in 13 countries responded in the first months of the crisis. Using primary and secondary data and combining the Multi-Level Perspective with social innovation approaches, we highlight the innovations and adaptations that emerged in ALFS, and how these changes have created or supported the sustainability transition in production and consumption systems. In particular, we show how the combination of social and technological innovation, greater citizen involvement,…
