Brujería europea y vudú haitiano
No full textLa influencia de la brujería europea en el vudú haitiano, muestra una intensidad muy elevada dentro del conjunto de componentes de este sistema mágico-religioso. Así, uno de los principales hechizos del Vudú en Haití, les expéditions o l’envoi morts, tiene claras referencias en las prácticas llevadas a cabo anteriormente en la península Ibérica y Canarias pero también en la antigua Roma. La tradición mágico-religiosa de Europa se muestra como determinante en el caso de las muñecas mágicas, como prueban los rituales presentes en Canarias con origen en la península Ibérica, así como la influencia de los poppets ingleses. Los zombi sufren una transmutación, despiertan al probar la sal, salvando su alma, recuperándola, de modo similar a como se utilizaba este elemento en la Edad Media europea. Los loups-garous, brujas vampiras que succionan a los niños, son una versión prácticamente exacta de las estriges del mundo grecorromano, seres que continúan apareciendo en el ámbito cultural europeo y próximo-oriental en los siglos siguientes, y que fueron reflejados por el pintor Francisco de Goya en varias obras. Estas brujas se metamorfosean en animales, tanto en la España visigoda como en la de los siglos XVI a XIX, así como en Haití. Finalmente, el “poder de los ojos” lo vemos en las brujas del noroeste de España y en los hungan y las mambo haitianos, de forma muy semejante.
The influence of European witchcraft in Haitian Voodoo shows a very high intensity within the set of components of this magical-religious system. Thus, one of the main spells of Haitian Voodoo, les expéditions or l'envoi morts, has clear references in the practices carried out previously in the Iberian Peninsula and the Canary Islands but also in ancient Rome. The magic-religious tradition of Europe is shown to be determinant in the case of magic dolls, as evidenced by the rituals present in the Canary Islands with origins in the Iberian Peninsula as well as the influence of the English poppets. The zombies undergo a transmutation, they wake up when they taste salt, saving their soul, recovering it, in a similar way to how this element was used in the European Middle Ages. The loups-garous, vampire witches that suck children, are an almost exact version of the Strix of the Greco-Roman world, beings that continue to appear in the European and Near Eastern cultural sphere in the following centuries, and that were reflected by the painter Francisco de Goya in several works. These witches metamorphose into animals, both in Visigothic Spain and in Spain from the 16th to the 19th centuries, as well as in Haiti. Finally, the “power of the eyes” is seen in the witches of northwestern Spain and in the Haitian hungan and mambo, in a very similar way
Synergistic activity of silver nanoparticles and antibiotics: apramycin against <i>Escherichia coli</i>
No full textThe combination of silver nanoparticles and conventional antibiotics could be a promising alternative strategy to fight against antimicrobial resistance. The occurrence of synergistic bactericidal activity between these combinations is supported by a large number of studies, but there is still a great lack of information about the action mechanisms. In this study, a direct analytical method for the detection and quantification of silver content in cells based on single cell inductively coupled plasma mass spectrometry (SC-ICP-MS), in combination with microscopy and microbiological techniques, has been used. Quantification of silver accumulated in Escherichia coli bacteria exposed to combinations of silver(I) or silver nanoparticles and apramycin can help elucidate the synergistic mechanisms of silver–antibiotic combinations. The combination of silver with apramycin resulted in the occurrence of synergistic effects, allowing the reduction of silver(I), silver nanoparticle and apramycin concentrations (from 4- to 16-fold) while preserving the individual bactericidal effects of each antimicrobial. Severe damage in bacteria walls, including double membrane rupture and cytoplasm leakage, was observed when the combination of apramycin and silver was used. In general, the presence of apramycin has promoted silver uptake by bacteria

Expert Consensus on Buffer Zone Governance: Interface Concepts, Ecosystem Service Priorities, and Territorial Strategies Around Cerro Castillo National Park, Chile
No full textBuffer zones around protected areas (PA) face complex governance challenges as territorial transitions accelerate globally, yet limited consensus exists on their definition, ecosystem service (ES) priorities, and management strategies. This study employed a three-round Delphi methodology with 23 transdisciplinary experts to build consensus on buffer zone governance around Cerro Castillo National Park in Chilean Patagonia, using the IPBES ecosystem services framework to structure the analysis. Round 1 employed open-ended questions to explore expert perspectives, Round 2 evaluated 56 statements and 15 strategic components using structured questionnaires, and Round 3 refined non-consensus items. Experts achieved 76.7% overall consensus across three thematic areas: PA interface conceptualization (79.2% consensus on 24 statements), ES assessment (91.2% consensus on 34 statements), and territorial transition strategies (15 components evaluated). Water-related services achieved unanimous agreement across multiple IPBES categories, revealing their potential as boundary objects bridging conservation and development perspectives. Educational approaches and voluntary compliance emerged as high-feasibility strategic components, while regulatory frameworks showed high importance but implementation uncertainty. The study demonstrates that structured expert consultation can identify collaborative pathways for buffer zone governance, with water services providing concrete entry points for multi-stakeholder cooperation and education-based strategies offering promising implementation pathways for sustainable territorial transitions
Unveiling the gap: technical-tactical performance differences between main and qualifying draws in professional padel
No full textThis study aimed to investigate technical-tactical differences between main draw vs. qualifying draw matches in male and female professional padel players. Through systematic observation, data were collected from 39 matches (4,585 points) of the professional male qualifying draw (n = 9) and main draw (n = 13), and female qualifying draw (n = 8) and main draw (n = 9) during the 2023 World Padel Tour Finland Padel Open tournament. Using chi-square analysis and corrected standardized residuals (CSR), the results showed significant differences between draws for final shot relative to the side of the play, serving efficiency and the type of final shot. Left side male players made more forced errors (CSR = 2.8) and fewer unforced errors (CSR = 3.2) in main draw compared to qualifying draw matches. While players were in the return game, both male and female players made a higher proportion of forced errors (CSR = 3.3; CSR = 2.7) and a lower proportion of unforced errors (CSR = 3.3; CSR = 2.3) in main draw compared to qualifying draw matches. Specific shot-type analysis revealed that male and female players made varying numbers of winners, forced errors and unforced errors with certain types of shots in the main vs. qualifying draw matches. These findings provide valuable insights for players and coaches to optimize their technical-tactical strategies based on the competition draw and match context
Quantum Computing Applications for Compact Heat Exchanger Design and Assessment
No full textThis paper explores possible implementations of quantum computing technologies, namely the quantum annealing and the quantum walk search algorithm, to solve fluid dynamics problems related to the design and assessment of compact heat exchangers for aeronautical environmental control and thermal management systems, as well as several other science and engineering applications, e.g. oil and gas refinery process. The purpose of this paper is to introduce two alternative implementations to the already assessed numerical resolution of Navier–Stokes equations or the resolution of analog quantum mechanical problem, highlighting how the use of quantum annealing and a classification algorithm (quantum walk search algorithm) can be implemented for the resolution of a lumped-characteristic analytical model of the heat transfer inside a compact heat exchanger, also in case of two-phase refrigerant fluid, for the use during design phase of environmental control system, e.g. provide the design engineers with a relatively simple and quick to use tool, which provides a reasonable result with an easily interpretable physical meaning. We start with a simple two-phase flow within a single-pass mini-channel heat exchanger, describing the mathematical formulation of the problem followed by a simplified implementation of the proposed quantum approaches, highlighting the main procedures of the calculation as well as the practical implications, advantages and disadvantages of the proposed method, e.g. a limited number of CFD simulations are required to evaluate air side heat transfer coefficient and pressure drop for particular designs within the defined design space, and the specific hardware required to implement the quantum process
ProteinLIPs: a web server for identifying highly polar and poorly packed interfaces in proteins
No full textMotivation
The stability of protein interfaces influences protein dynamics and unfolding cooperativity. Although in some cases the dynamics of proteins can be deduced from their topology, much of the stability of an interface is related to the complementarity of the interacting parts. It is also important to note that proteins that display non-cooperative unfolding cannot be rationally stabilized unless the regions that unfold first are known. Being able to identify protein interfaces that are significantly less stable would contribute to our understanding of protein dynamics and be very valuable in guiding the rational stabilization of proteins with non-two-state unfolding equilibria.
Results
We introduce ProteinLIPs, a web server that detects interfaces of high polarity and low packing density, termed LIPs. Each LIP consist of a continuous sequence segment (mLIP) plus its contacting residues (cLIP). ProteinLIPs scans monomeric and oligomeric proteins and provides graphical sequence profiles and interactive 3D visualizations of the detected LIPs. Statistical analysis of 53 protein domains from 10 superfamilies shows the two parts of a LIP present distinct characteristics. mLIPs are conserved, structurally unstable and enriched in polar residues, whereas cLIPs are more stable, less conserved, and enriched in apolar residues. Besides, cLIPs are enriched in small-molecule binding site residues, suggesting they play a role in ligand interaction, likely facilitated by instability of the associated mLIPs. ProteinLIPs provides a user-friendly platform for the automated identification and visualization of LIPs and can be used to guide the engineering of non-two-state proteins where LIPs constitute preferential targets for thermostabilization
Facial morphology in the adult Spanish population: a comprehensive anthropometric study using 3D photoanthropometry
No full textThis study elucidates the anthropometric variations of the Spanish facial features through the presentation of extensive adult population reference data derived from photoanthropometric measurements and indices. A total of 535 Spanish individuals (215 men and 320 women) of legal age participated in this research. Using 3D facial images captured by a portable white light led 3D scanner, 21 cephalometric landmarks were identified. Subsequently, 21 linear measurements and 20 proportionality indices of the head and face based on standard traditional measurements, were calculated. Descriptive statistics, including the mean value, standard deviation, minimum value, maximum value, and the first, second, and third quartiles were determined for each measurement and index. Furthermore, potential differences between sexes (male and female) and age group (young adulthood and the middle/older adulthood), as well as associations between measurements and body mass index were assessed. Results revealed statistically significant differences between male and female individuals in 25 of the 27 measurements, with male exhibiting higher means. Significant differences were observed in 11 of the 21 indices studied, with six higher in males and five higher in females. Correlation analysis between measures and indices with BMI showed a weak statistically significant association with lower facial area. Age group comparisons indicated significant differences in over half of the variables analyzed, predominantly affecting the eyes, nose, mouth, and mandible. These findings contribute to the establishment of reference anthropometric data for the Spanish population and underscore the importance of tailored approaches in facial morphological studies to ensure the generation of accurate and applicable results
