The Variational Modeling of Hierarchical Structured Deformations

Hierarchical (first-order) structured deformations are studied from the variational point of view. The main contributions of the present research are the first steps, at the theoretical level, to establish a variational framework to minimize mechanically relevant energies defined on hierarchical structured deformations. Two results are obtained here: (i) an approximation theorem and (ii) the assignment of an energy to a hierarchical structured deformation by means of an iterative procedure. This has the effect of validating the proposal made in Deseri and Owen (J. Elast. 135:149-182, 2019) to study deformations admitting slips and separations at multiple submacroscopic levels. An explicit example is provided to illustrate the behavior of the proposed iterative procedure and relevant directions for future research are highlighted

Lactobacillus plantarum IFPL935 impacts colonic metabolism in a simulator of the human gut microbiota during feeding with red wine polyphenols

The colonic microbiota plays an important role in the bioavailibility of dietary polyphenols. This work has evaluated the impact on the gut microbiota of long-term feeding with both a red wine polyphenolic extract and the flavan-3-ol metabolizer strain Lactobacillus plantarum IFPL935. The study was conducted in the dynamic Simulator of the Human Intestinal Microbial Ecosystem (SHIME). The feeding of the gut microbiota model with red wine polyphenols caused an initial decrease in the counts of total bacteria in the ascending colon (AC), with Bacteroides, Clostridium coccoides/Eubacterium rectale and Bifidobacterium being the most affected bacterial groups. The bacterial counts recovered to initial numbers faster than the overall microbial fermentation and proteolysis, which seemed to be longer affected by polyphenols. Addition of L. plantarum IFPL935 helped to promptly recover total counts, Lactobacillus and Enterobacteriaceae and led to an increase in lactic acid formation in the AC vessel at the start of the polyphenol treatment as well as butyric acid in the transverse (TC) and descending (DC) vessels after 5 days. Moreover, L. plantarum IFPL935 favoured the conversion in the DC vessel of monomeric flavan-3-ols and their intermediate metabolites into phenylpropionic acids and in particular 3-(3′- hydroxyphenyl)propionic acid. The results open the possibilities of using L. plantarum IFPL935 as a food ingredient for helping individuals showing a low polyphenol-fermenting metabotype to increase their colonic microbial capacities of metabolizing dietary polyphenols. © 2014 Springer-Verlag.The authors acknowledge funding from the Spanish Ministry for Science and Innovation (AGL2009-13361-C02-00, AGL2010-17499, AGL2012-35814, AGL2012-40172-C02-01, and Consolider Ingenio 2010 FUN-C-FOOD CSD2007-00063), the Comunidad de Madrid (ALIBIRD P2009/AGR-1469), the INIA (RM2011-00003-00-00) and CYTED (IBEROFUN 110 AC0386).

2023 IMEKO TC-4 International Conference on Metrology for Archaeology and Cultural Heritage

This work summarizes the results of a three-year project focused on the archaeometrical study of a collection of about one thousand pre-Roman glass beads found at the archaeological site of Pintia (Valladolid, Spain), located at the interior of Iberia. In addition to the morphological and contextual analysis of the entire collection, a representative set of 150 samples, including several unique and exquisite polychrome beads, have been studied in detail by diverse archaeometric techniques such as Raman spectroscopy, X-ray fluorescence, PIXE/PIGE, X-ray tomography, among others. The combined use of these techniques provided valuable data about the production processes of the polychrome beads. Remarkably, some previous conceptions about their fabrication have been modified, and evidence about their production in secondary workshops has been provided. Moreover, hints about the origin of the primary glasses employed in all the studied samples have been obtained, suggesting their origin was scattered between Egypt and Syria-Palestine

Nutritional and Growth Effect of Insect Meal Inclusion on Seabass (Dicentrarchuss labrax) Feeds

This work studies the effect of high-level fish meal replacement with insect meal: YW meal (obtained from Tenebrio larvae fed a broiler diet), BSF meal (from hermetia larvae fed broilers diet), BSFm meal (obtained from hermetia larvae fed discard fish) on growth performance nutritive indices and in vitro digestibility of Dicentrarchus labrax juvenile. Three different insect meals were used: BSF meal from hermetia larvae fed broilers diet; BSF improve (BSFm) obtained from hermetia larvae fed discarded fish; YW meal obtained from the larvae of Tenebrio fed a broiler diet. Five diets were used, a control (C) diet and four experimental diets by replacing fishmeal with insect meal from BSF at 30% and 50% (BSF30 and BSF50) substitutions, BSFm at 50% substitution (BSF50 m) and YM at 50% substitution (YW50). Nutritional and growth indices worsened by including insect meal, especially for hermetia meal at 50% substitution, BSF50 and BSF50 m. The internal organs’ weight reflected the growth of the fish fed each experimental diet. No differences were found in fillet composition. Nevertheless, under our experimental condition, YW replacement obtained better results than both BSF diets

Análisis arqueosismológico del conjunto arqueológico romano de Mulva- Munigua (Sevilla, España). Resultados preliminares

El conjunto arqueológico romano de Mulva-Munigua (Sevilla, España) presenta daños en las edificaciones que pueden ser interpretadas como resultado de la ocurrencia de un evento sísmico (Efectos Arqueológicos de los Terremotos: EAEs) a finales del siglo III A.D., fecha coincidente con el inicio del periodo de declive económico de este asentamiento romano. Para intentar establecer el posible origen sísmico de las deformaciones, se ha procedido al inventario y análisis de las estructuras deformadas presentes en el yacimiento. No obstante, algunas de estas deformaciones también se pueden interpretar como resultado de procesos gravitaciones asociados a la ladera Este de la colina sobre la que se sitúa parte del yacimiento. Las direcciones de máxima deformación (ey) obtenidas del análisis de EAEs indica dos direcciones preferentes de la deformación (o movimiento preferente del terreno): NNO-SSE y ENEOSO. Aunque los datos presentan una dispersión importante, se puede establecer que la orientación principal NNO-SSE es compatible con un evento sísmico situado en el borde norte del Valle del Guadalquivir. La orientación ENE-OSO podría relacionarse con un evento posterior, o más seguramente con procesos de ladera de carácter cosísmico o no.The Roman archaeological site of Mulva-Munigua (Sevilla, Spain) displays building damage features suggesting a seismic origin (Earthquake Archaeological Effects: EAEs). The proposed seismic event could be tentatively dated in the late 3rd century AD, coinciding with the beginning of the economic fall of the Roman Empire at Iberia. However, some of the recorded EAEs can be also interpreted as a result of intervening slope movements in the eastern hillslope of this roman site. The inventory and analysis of the proposed EAEs make possible to discern between seismic oriented damage and other causes. In spite of the data show a significant dispersion, their analysis result in two different orientations of maximum deformation (ey) or preferential ground movement: NNW-SSE and ENE-WSW. The main ey orientation (NNW-SSE) can be tentatively related to a seismic event occurred in the environs of the northern border of the Guadalquivir Depression. The secondary orientation (ENE-WSW) can be interpreted as a consequence of latter slope movements triggered (or not) by other ancient earthquakes
