Olive Oil at the Border of the Roman Empire. Stamps on Baetican Dressel 20 found on the Tyne-Solway Isthmus

This paper focuses on Dressel 20 stamps found on the Tyne-Solway isthmus and Hadrian's Wall from the first to the fourth century AD. The aim is to describe olive oil imports to the limes of Britannia by focusing on the distribution of stamps along the wall, their location and the most common stamp dies. This research also provides an accurate analysis of olive oil exportation by studying the workshops (figlinae) where these stamps were produced, and by describing the economic activity of figlinae from a chronological and administrative standpoint

The Tituli Vasis Fictilibus Inscripti from CIL IV. Computerization and Quantitative Analysis of their Epigraphic Objects

The computerization of amphoric epigraphy from volume IV of Corpus Inscriptionum Latinarum is very significant for the economic studies of the Roman world. The value of their quantitative and qualitative characteristics has been obtained by their contraposition with tituli picti published in other works. This work shows the distribution of the tituli vasis fictilibus inscripti from CIL IV, the related bibliography that supports their study, and the strategies followed for its organization and interpretation. The documentation was very fragmented, published in multiple supplements by different authors over a century, and was in need of a summarization. The subsequent analysis of this summarized documentation shows the thematic composition of the tituli picti and the typological classification of their epigraphic carriers according to the authors of CIL IV

Water-Gas Shift Reaction on K/Cu(111) and Cu/K/TiO2(110) Surfaces: Alkali Promotion of Water Dissociation and Production of H2

The addition of potassium atoms to Cu(111) and Cu/TiO2(110) surfaces substantially enhances the rate for water dissociation and the production of hydrogen through the water-gas shift reaction (WGS, CO + H2O → H2 + CO2). In the range of temperatures investigated, 550-625 K, Cu/K/TiO2(110) exhibits a WGS activity substantially higher than those of K/Cu(111), Cu(111), and Cu/ZnO(0001̄) systems used to model an industrial Cu/ZnO catalyst. The apparent activation energy for the WGS drops from 18 Kcal/mol on Cu(111) to 12 Kcal/mol on K/Cu(111) and 6 Kcal/mol on Cu/K/TiO2(110). The results of density functional calculations show that K adatoms favor the thermochemistry for water dissociation on Cu(111) and Cu/TiO2(110) with the cleavage of an O-H bond occurring at room temperature. Furthermore, at the Cu/K/TiO2 interface, there is a synergy, and this system has a unique ability to dissociate the water molecule and catalyze hydrogen production through the WGS process. Therefore, when optimizing a regular catalyst, it is essential to consider mainly the effects of an alkali promoter on the metal-oxide interface.US Department of Energy DE-SC0012704Ministerio de Economía y Competitividad CTQ2015-64669-

Productive landscapes and trade networks in the Roman Empire

La investigación actual sobre la economía de los alimentos en el mundo romano queda reflejada en esta obra, que aborda la producción y distribución de tales bienes fundamentales desde el estudio de casos y la innovación metodológica. Su configuración parte de una iniciativa del proyecto europeo EPNet, que reunió a los distintos autores participantes en el volumen con motivo de una sesión específica de la 27.ª Theoretical Roman Archaeology Conference (Durham, marzo de 2017). Aunque también se trata el abastecimiento de trigo, las contribuciones se dedican mayoritariamente al aceite y el vino. Los casos de estudio se concentran en el occidente romano, con especial atención a Italia e Hispania. Se incluyen contextos productivos y de redistribución, particularmente en los asentamientos militares fronterizos y la capital. Metodológicamente destacan las estrategias de cuantificación, el análisis SIG y la modelización. Se contrastan aspectos geográficos y arqueológicos de las diversas zonas de estudio para extraer conclusiones relativas a los patrones de asentamiento rural, la producción de alimentos y envases anfóricos, y sus redes de distribución comercial. De tal forma se dibuja un panorama amplio, vertebrado en torno a una cuestión clave para el funcionamiento y la sostenibilidad del Imperio: la economía alimentaria. Este amplio abanico metodológico resulta sugerente para la orientación de nuevas investigaciones que, de forma complementaria, se unan para profundizar en las razones del prolongado éxito de la cultura romana

Centro para el Estudio de la Interdependencia Provincial en la Antigüedad Clásica CEIPAC

En 1988 se creó, por primera vez, una cátedra de Historia Antigua en la Cataluña postguerra civil. La cátedra de Historia Antigua había sido asociada a la de Prehistoria, regida por el profesor. D. Joan Maluquer de Montes i Nicolau, quien no aprovechó la oportunidad de dividir ambas cátedras en el momento, en el que tanto la asignatura de Prehistoria como la de Historia Antigua se convirtieron en dos materias troncales en los planes de estudio

Association between Use of Enhanced Recovery after Surgery Protocol and Postoperative Complications in Total Hip and Knee Arthroplasty in the Postoperative Outcomes Within Enhanced Recovery after Surgery Protocol in Elective Total Hip and Knee Arthroplasty Study (POWER2)

Importance: The Enhanced Recovery After Surgery (ERAS) care protocol has been shown to improve outcomes compared with traditional care in certain types of surgery. Objective: To assess the association of use of the ERAS protocols with complications in patients undergoing elective total hip arthroplasty (THA) and total knee arthroplasty (TKA). Design, Setting, and Participants: This multicenter, prospective cohort study included patients recruited from 131 centers in Spain from October 22 through December 22, 2018. All consecutive adults scheduled for elective THA or TKA were eligible for inclusion. Patients were stratified between those treated in a self-designated ERAS center (ERAS group) and those treated in a non-ERAS center (non-ERAS group). Data were analyzed from June 15 through September 15, 2019. Exposures: Total hip or knee arthroplasty and perioperative management. Sixteen individual ERAS items were assessed in all included patients, whether they were treated at a center that was part of an established ERAS protocol or not. Main Outcomes and Measures: The primary outcome was postoperative complications within 30 days after surgery. Secondary outcomes included length of stay and mortality. Results: During the 2-month recruitment period, 6146 patients were included (3580 women [58.2%]; median age, 71 [interquartile range (IQR), 63-76] years). Of these, 680 patients (11.1%) presented with postoperative complications. No differences were found in the number of patients with overall postoperative complications between ERAS and non-ERAS groups (163 [10.2%] vs 517 [11.4%]; odds ratio [OR], 0.89; 95% CI, 0.74-1.07; P =.22). Fewer patients in the ERAS group had moderate to severe complications (73 [4.6%] vs 279 [6.1%]; OR, 0.74; 95% CI, 0.56-0.96; P =.02). The median overall adherence rate with the ERAS protocol was 50.0% (IQR, 43.8%-62.5%), with the rate for ERAS facilities being 68.8% (IQR, 56.2%-81.2%) vs 50.0% (IQR, 37.5%-56.2%) at non-ERAS centers (P <.001). Among the patients with the highest and lowest quartiles of adherence to ERAS components, the patients with the highest adherence had fewer overall postoperative complications (144 [10.6%] vs 270 [13.0%]; OR, 0.80; 95% CI, 0.64-0.99; P <.001) and moderate to severe postoperative complications (59 [4.4%] vs 143 [6.9%]; OR, 0.62; 95% CI, 0.45-0.84; P <.001) and shorter median length of hospital stay (4 [IQR, 3-5] vs 5 [IQR, 4-6] days; OR, 0.97; 95% CI, 0.96-0.99; P <.001). Conclusions and Relevance: An increase in adherence to the ERAS program was associated with a decrease in postoperative complications, although only a few ERAS items were individually associated with improved outcomes

Understanding the Photocatalytic Properties of Pt/CeOx/TiO2: Structural Effects on Electronic and Optical Properties

Ceria‐titania interfaces play a crucial role in different chemical processes but are especially promising for the photocatalytic splitting of water using light in the visible wavelength region when Pt is added to the system. However, the complexity of this hierarchical structure hampers the study of the origin of its outstanding properties. In this article, the structural, electronic and optoelectronic properties of CeO2/TiO2 systems containing 1D, 2D, and 3D particles of ceria are analyzed by means of density functional calculations. Adsorption sites and vacancy effects have been studied to model Pt adsorption. Density of states calculations and absorption spectra simulations explain the behavior of these systems. Finally, these models are used for the screening of other metals that can be combined with this heterostructure to potentially find more efficient water splitting photocatalysts.Ministerio de Economía y Competitividad (CTQ2015-64669-P)European FEDERU.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, and Catalysis Science Program (contract No. DE-SC0012704
