Propuesta de un sistema de identificación forense basado en métodos de marcado dental
[ES] Introducción: identificar a una persona tras un trágico suceso conlleva una gran responsabilidad no sólo desde la perspectiva emocional o afectiva, sino también en el ámbito económico-legal. Desde la Antigua Roma la OdontologÃa ha servido como método de identificación forense. Los tejidos dentales poseen gran resistencia ante condiciones adversas, lo que les hace idóneos como método de identificación.
Objetivos: establecer una propuesta de identificación forense basada en la colocación de una miniplaca marcada con un código de validez internacional en una ubicación estandarizada de un diente y comprobar su resistencia a la temperatura

Experimental Assessment of a Centralised Controller for High-RES Active Distribution Networks
This paper assesses the behaviour of active distribution networks with high penetration of
renewable energy sources when the control is performed in a centralised manner. The control assets
are the on-load tap changers of transformers at the primary substation, the reactive power injections
of the renewable energy sources, and the active and reactive power exchanged between adjacent
feeders when they are interconnected through a DC link. A scaled-down distribution network is used
as the testbed to emulate the behaviour of an active distribution system with massive penetration of
renewable energy resources. The laboratory testbed involves hardware devices, real-time control,
and communication infrastructure. Several key performance indices are adopted to assess the effects
of the different control actions on the system’s operation. The experimental results demonstrate
that the combination of control actions enables the optimal integration of a massive penetration of
renewable energy.Ministerio de EconomÃa y Competitividad ENE2015-69597-RMinisterio de EconomÃa y Competitividad PCIN-2015-043Ministerio de EconomÃa y Competitividad ENE2017-84813-
Biodegradation of olive washing wastewater pollutants by highly efficient phenol-degrading strains selected from adapted bacterial community
The bacterial community of an olive washing water (OWW) storage basin was characterized, by both cultivation and cultivation-independent methods. PCR-TGGE fingerprints analysis of different samples, taken along the olive harvesting season, revealed important variations of the bacterial community structure showing rapid establishment of prevalent bacterial populations. Several bacteria, isolated from OWW, were cultivated, in media containing increasing amounts of polyphenols, in order to select high phenol-degrading strains for the effluent pollutants reduction. Strains PM3 and PM15, affiliated to Raoultella terrigena and Pantoea agglomerans by 16S rRNA gene sequencing, were selected and used for OWW biological treatment under batch conditions in shake flasks cultures. The OWW content of phenols, BOD5, COD and colour, was reduced by 93, 91, 89 and 62%, respectively, permitting effluent disposal and/or reuse with no additional treatments.This research was supported by European project Algatec (FP7/SME/2008/1/232331)

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics
Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset
Temporal Stability of Serum Concentrations of Cytokines and Soluble Receptors Measured Across Two Years in Low-Risk HIV-Seronegative Men
BackgroundProspective cohort studies often quantify serum immune biomarkers at a single time point to determine risk of cancer and other chronic diseases that develop years later. Estimates of the within-person temporal stability of serum markers partly assess the utility of single biomarker measurements and may have important implications for the design of prospective studies of chronic disease risk.MethodsUsing archived sera collected from 200 HIV-seronegative men at three visits spaced over approximately 2 years, concentrations of 14 biomarkers (ApoA1, sCD14, sgp130, sIL-6R, sIL-2Rα, sTNFR2, BAFF/BLyS, CXCL13, IFN-γ, interleukin [IL]-1β, IL-6, IL-8, IL-10, and TNF-α) were measured in a single laboratory. Age- and ethnicity-adjusted intraclass correlation coefficients (ICC) were calculated for each biomarker, and mixed linear regression models were used to examine the influence of age, ethnicity, season, and study site on biomarker concentrations.ResultsAcross all three study visits, most biomarkers had ICC values indicating fair to excellent within-person stability. ApoA1 (ICC = 0.88) and TNF-α (ICC = 0.87) showed the greatest stability; the ICC for IL-8 (ICC = 0.33) was remarkably less stable. The ICCs were similar when calculated between pairs of consecutive visits. The covariables did not influence biomarker levels or their temporal stability. All biomarkers showed moderate to strong pairwise correlations across visits.ConclusionsSerum concentrations of most evaluated immune biomarkers displayed acceptable to excellent within-person temporal reliability over a 2-year period. Further investigation may be required to clarify the stability of IL-8.ImpactThese findings lend support to using these serologic immune biomarkers in prospective studies investigating associations with chronic diseases
