Assessment and Reduction of the Seismic Vulnerability of a Stone Masonry Vault

A numerical approach is presented to assess the seismic vulnerability of barrel masonry vaults and evaluate the eectiveness of a traditional retrofitting intervention consisting in the reinforcement of the extrados. A linear elastic no–tension model is adopted to cope with the negligible strength in tension of ancient brick and stone masonry and perform a two–dimensional finite element analysis of arch–like sections. Instead of implementing conventional load history analysis or limit load analysis, the minimization of the relevant strain energy function is implemented to solve the non–linear equilibrium under the effect of dierent load scenarios. A segmental barrel vault made of stone masonry is investigated in an ancient building under static and seismic loads. The collapse load of the structural element is computed before and after the intervention and the reduction achieved in terms of seismic vulnerability is evaluated as prescribed by technical codes

The relationship between the language of scientific publication and its impact in the field of public and collective health

The language of scientific publications is a crucial factor when seeking to reach an international audience, because it affects linguistic accessibility and the geographical reach of research results. English is the language of science and the fact that it can be understood by most readers represents an undeniable advantage. Moreover, the fact that a large proportion of Ibero-American research has been published in national languages, is often cited as one of the reasons for its limited exposure. The purpose of this study was to analyze the relationship between scientific output published in a native language and its degree of exposure and impact in the field of Public and Collective Health. This bibliometric study was carried out based on the scientific output data obtained from the most prolific countries that are members of the SciELO (Scientific Electronic Library Online) Network in Public and Collective Health, in the 2011-2018 period. The data was collected from the SciELO Citation Index database (SciELO CI), which was integrated into the larger WoS platform in 2014 and was chosen on account of its importance as one of the few regional indexes that is still scarcely used in studies of this nature. The data shows that Brazilian articles in Portuguese had the greatest citation impact on publications in its own language (48.7%), while its articles in English present practically the same impact (48.5%) on Portuguese publications, followed by 34.5% on Spanish publications. The impact on the national language is also significant in the case of both Mexican and Spanish publications, to whom the percentage of citing articles in Spanish, for documents cited in the same language, is higher than for documents cited in English (respectively 1.6 and 1.8). The same applies to Portuguese and US-American articles where, respectively 56.6% and 43.9% of the citing articles are in their native language. Cuban and Peruvian articles have more than 90% of their citing articles in the national language. In contrast, the USA and Brazil are countries that have a greater citation impact on other languages, especially when published in Spanish. The extent of exposure of a given language of the scientific publication varies per the country´s scientific output. In the case of Brazilian and US-American publications, including publications in the national languages of these countries, the effects on audiences in other languages can be measured by the citation impact. Furthermore, the degree of exposure of certain publications suggests that SciELO CI represents a useful database for evaluating local scientific output, and this can be observed, particularly, for publications in the national language

The relationship between the publication language and its impact on public and collective health

Objective: The purpose of this study is to analyze the relationship between scientific output published in a native language and its degree of exposure and impact on Public and Collective Health. Methods: This bibliometric study was carried out on the basis of the scientific production from the most prolific countries that are members of the SciELO Network, in Public and Collective Health, in the period 2011-2015. The data was collected from the SciELO Citation Index database (SciELO CI) and the citations were analysed by language and source. Findings: Brazilian publications in Portuguese had the greatest citation impact in the same language (55.7%), while its publications in English had 47.9% of impact in Portuguese and 34.4% in Spanish publications (34.4%). The impact on the national language is also significant to Colombian and Spanish publications. To Spain, the percentage of citing articles in Spanish for papers in the same language is more than twice that of its impact in English. To US-American articles, 42.5% of the citations are in a native language when published in English. Cuban and Peruvian publications presented more than 90% of their impact in the national language. In contrast, the USA and Brazil presented greater citation impact on other languages, especially when publishing in Spanish. Conclusion: The extent of the exposure of a publication language varies in accordance with the country´s scientific output. In the case of Brazilian and US-American publications, the effects on audiences in other languages can be measured by the citation impact. Furthermore, the degree of exposure offered by SciELO CI makes it useful for evaluation, particularly for publications in the national language

A comparative evaluation of 3 different free-form deformable image registration and contour propagation methods for head and neck MRI : the case of parotid changes radiotherapy

Purpose: To validate and compare the deformable image registration and parotid contour propagation process for head and neck magnetic resonance imaging in patients treated with radiotherapy using 3 different approachesthe commercial MIM, the open-source Elastix software, and an optimized version of it. Materials and Methods: Twelve patients with head and neck cancer previously treated with radiotherapy were considered. Deformable image registration and parotid contour propagation were evaluated by considering the magnetic resonance images acquired before and after the end of the treatment. Deformable image registration, based on free-form deformation method, and contour propagation available on MIM were compared to Elastix. Two different contour propagation approaches were implemented for Elastix software, a conventional one (DIR_Trx) and an optimized homemade version, based on mesh deformation (DIR_Mesh). The accuracy of these 3 approaches was estimated by comparing propagated to manual contours in terms of average symmetric distance, maximum symmetric distance, Dice similarity coefficient, sensitivity, and inclusiveness. Results: A good agreement was generally found between the manual contours and the propagated ones, without differences among the 3 methods; in few critical cases with complex deformations, DIR_Mesh proved to be more accurate, having the lowest values of average symmetric distance and maximum symmetric distance and the highest value of Dice similarity coefficient, although nonsignificant. The average propagation errors with respect to the reference contours are lower than the voxel diagonal (2 mm), and Dice similarity coefficient is around 0.8 for all 3 methods. Conclusion: The 3 free-form deformation approaches were not significantly different in terms of deformable image registration accuracy and can be safely adopted for the registration and parotid contour propagation during radiotherapy on magnetic resonance imaging. More optimized approaches (as DIR_Mesh) could be preferable for critical deformations

The purpose of this study was to examine the effect of adding various concentrations of dragon fruit peel extract (DFPE) in Tris-egg yolk diluent (TEY) on the quality of bligon goat spermatozoa. Semen was collected twice a week using the artificial vaginal method from three year old bligon male goats with normal body conditions and reproductive organs. After the macroscopic and microscopic evaluation, good quality semen with a sperm motility of > 70%, a concentration of > 800 x 106 mL-1, and abnormality of < 15 %, was diluted with TEY + DFPE at a concentration of 0% (P0), 2% (P1), 4% (P2), 6% (P3), 8% (P4), dan 10% (P5). The semen which still had a motility ≥ 70% was then stored at a temperature of 3-5oC. Evaluation of the quality of spermatozoa  was carried out every 24 hours until the motility decrease to 40%. The results showed that from day 1 to day 5 of preservation, spermatozoa preserved in TEY + 6% DFPE diluent (P3) had higher motility and viability (P<0,05) than other treatments. The abnormalities of spermatozoa until the 5 day of preservation were below 6%, but showed a significant difference (P<0,05) between treatments that received DFPE suplemention with control (P0). It was concluded that the addition of DFPE in TEY up to 6% could reduce the decrease in sperm quality of bligon goats during in vitro preservation.Tujuan dari penelitian ini adalah untuk menguji pengaruh penambahan berbagai konsentrasi ekstrak kulit buah naga (EKBN) dalam pengencer Tris–kuning telur (T-KT) terhadap kualitas spermatozoa kambing bligon.

La città, il viaggio, il turismo: Percezione, produzione e trasformazione

[English]:The city as a destination of the journey in his long evolution throughout history: a basic human need, an event aimed at knowledge, to education, to business and trade, military and religious conquests, but also related to redundancies for the achievement of mere physical or spiritual salvation. In the frame of one of the world's most celebrated historical city, the cradle of Greek antiquity, myth and beauty, travel timeless destination for culture and leisure, and today, more than ever, strongly tending to the conservation and development of their own identity, this collection of essays aims to provide, in the tradition of AISU studies, a further opportunity for reflection and exchange between the various disciplines related to urban history./ [Italiano]:La città come meta del viaggio nella sua lunga evoluzione nel corso della storia: un bisogno primario dell'uomo, un evento finalizzato alla conoscenza, all'istruzione, agli affari e agli scambi commerciali, alle conquiste militari o religiose, ma anche legato agli esodi per il conseguimento della mera salvezza fisica o spirituale. Nella cornice di una delle città storiche più celebrate al mondo, culla dell'antichità greca, del mito e della bellezza, meta intramontabile di viaggi di cultura e di piacere, e oggi, più che mai, fortemente protesa alla conservazione e alla valorizzazione della propria identità, questa raccolta di saggi intende offrire, nel solco della tradizione di studi dell'AISU, un'ulteriore occasione di riflessione e di confronto tra i più svariati ambiti disciplinari attinenti alla storia urbana
