Study of Electrochemical and Biological Characteristics of As-Cast Ti-Nb-Zr-Ta System Based on Its Microstructure

[EN] The quaternary Ti-Nb-Zr-Ta (TNZT) alloy was successfully cast-fabricated with the objective to be used in the medical field. Samples' microstructure was compared to CP-Ti and Ti-6Al-4V (control samples) and related to corrosion, ion release and biological properties. As-cast TNZT was formed with large grain sizes (285 m) compared to the ultrafine grain sizes of CP-Ti (11 m) and the + ultrafine grain sizes of 1.45 m and 0.74 m. Hardness and flexural elastic moduli (94 HV and 43 GPa) came close to the biological structures, such as dentin and enamel values. The ion release mechanism of as-cast TNZT was significantly lesser than CP-Ti and Ti-6Al-4V, which can be related to the difference in samples¿ grain sizes and chemical compositions. However, the corrosion rate was higher than for the control samples; this way offers corrosion properties inferior with respect to the properties obtained in the reference materials. Biological assays demonstrated that the two-cell (hDPSCs and MG-63) lineage studied presented good adhesion and capability to differentiate in bone cells on the as-cast TNZT surface, and no cytotoxicity effects were found. Details and reasons based on samples¿ microstructure are discussed.The authors thank the Spanish Ministerio de Economia y Competitividad for Research Project RTI2018-097810-B-I00 and the European Commission for FEDER funds.Correa Rossi, M.; Navarro, B.; Milian Medina, L.; Vicente-Escuder, Á.; Amigó, V.

Orchid fleck dichorhavirus movement protein shows RNA silencing suppressor activity.

[EN] To counteract RNA interference-mediated antiviral defence, virus genomes evolved to express proteins that inhibit this plant defence mechanism. Using six independent biological approaches, we show that orchid fleck dichorhavirus citrus strain (OFV-citrus) movement protein (MP) may act as a viral suppressor of RNA silencing (VSR). By using the alfalfa mosaic virus (AMV) RNA 3 expression vector, it was observed that the MP triggered necrosis response in transgenic tobacco leaves and increased the viral RNA (vRNA) accumulation. The use of the potato virus X (PVX) expression system revealed that the cis expression of MP increased both the severity of the PVX infection and the accumulation of PVX RNAs, further supporting that MP could act as an RNA silencing suppressor (RSS). From the analysis of the RSS-defective turnip crinkle virus (TCV), we do not find local RSS activity for MP, suggesting a link between MP suppressor activity and the prevention of systemic silencing. In the analysis of local suppressive activity using the GFP-based agroinfiltration assay in Nicotiana benthamiana (16 c line), we do not identify local RSS activity for the five OFV RNA1-encoded proteins. However, when evaluating the small interfering RNA (siRNA) accumulation, we find that the expression of MP significantly reduces the accumulation of GFP-derived siRNA. Finally, we examine whether the MP can prevent systemic silencing in 16c plants. Our findings show that MP inhibits the long-distance spread of RNA silencing, but does not affect the short-distance spread. Together, our findings indicate that MP is part of OFV's counter-defence mechanism, acting mainly in the prevention of systemic long-distance silencing. This work presents the first report of a VSR for a member of the genus Dichorhavirus.This work was supported by grant PID2020-115571RB-100 from the Spanish MCIN/AEI/10.13039/501100011033 granting agency and Fondo Europeo de Desarrollo Regional (FEDER), and by the company INVESTIR IMOVEIS LDTA from Brasilia, Brazil.Oliveira Leastro, M.; Pallás Benet, V.; Sánchez-Navarro, JÁ.

Performance of Ti-15Mo alloy obtained by powder metallurgy route weakly alloyed with Fe/Cr elements

[EN] Ti-15Mo alloy can be an excellent choice as a biomaterial for prostheses. This is due to the combination of good mechanical properties and biocompatibility. The Mo is a stabilizing element of the ß phase, which provides a smaller elastic modulus, reducing the risk of stress shielding that induces bone resorption. The present work shows the effect of minor additions of Fe or Cr on flexural fracture toughness in Ti-15Mo alloys obtained by Powder Metallurgy. The electrochemical results indicated that the Ti-15Mo-1Cr, showed greater resistance to corrosion, related to lower ß grain size, less porosity content compared to the other conditions. As the Ti-15Mo-1Fe and Ti-15Mo-3Fe presented more porosity in their microstructure, the saline composition inside the pores is different in concentration and thus makes diffusion difficult compared to other regular and more homogeneous zones. Besides, was verified the effect of the large grain size that decrease the corrosion resistance of the Ti-15Mo-3Cr, demonstrated two influences in the corrosion resistance, porosity and grain size. Toughness decreases with the addition of both elements, more pronounced with Fe than Cr. It is related with lower densification, higher porosity and greater proportion of phase ¿ in grain boundary due to the higher resistance of diffusion of Mo in Ti when Fe is present, which leads to failure by brittle fracture at lower shear stresses.Correa Rossi, M.; López Navarro, P.; Vicente-Escuder, Á.; Amigó, V.; Segovia-López, F.

Cross-guide Moreno directional coupler in empty substrate integrated waveguide

[EN] Substrate integrated waveguides (SIWs) combine the advantages of rectangular waveguides (low losses) and planar circuits (low cost and low profile). Empty substrate integrated waveguide (ESIW) has been proposed as a novel configuration in SIWs recently. This technology significantly reduces the losses of conventional SIW by removing its inner dielectric. The cross-guide directional coupler is a well-known low-profile design for having a broadband waveguide coupler. In this paper a cross-guide coupler with ESIW technique is proposed. In such a manner, the device can be integrated with microwave circuits and other printed circuit board components. It is the first time that a cross-guide coupler is implemented in ESIW technology. The designed, fabricated, and measured device presents good results as a matter of insertion loss of 1 dB (including transitions), reflection under 20 dB, coupling between 19.5 and 21.5 dB, and directivity higher than 15 dB over targeted frequency range from 12.4 GHz to 18 GHz. The coupler implemented in ESIW improves the directivity when compared to similar solutions in other empty substrate integrated waveguide solutions.This work was supported by the Ministerio de Economia y Competitividad, Spanish Goverment, under research projects TEC2013-47037-C5-3-R and TEC2013-47037-C5-1-R.

Survey on Drosophila suzukii natural short-term dispersal capacities using the mark-release-recapture technique

[EN] Spotted wing drosophila, Drosophila suzukii Matsumura (Diptera: Drosophilidae), has become a key pest for soft fruits and cherries in Europe in less than a decade since the first outbreak in 2007. Although this pest's passive dispersal ability has been observed over more than 1400 km in 1 year, active spread has not yet been extensively studied. A mark-release-recapture (MRR) method based on protein-marked flies was employed to determine the flight capacity of D. suzukii. Sterile marked flies were released and recaptured in a trap grid at increasing distances from 10 to 250 m from the releasing point to study flight distance during periods ranging from 3 h to 1 week. MRR experiments were replicated in the presence and absence of host fruits to study how they could affect dispersal behavior. The dispersal capacity of the Mediterranean fruit fly, Ceratitis capitata Wiedemann (Diptera: Tephritidae) was also studied under the same conditions. The results showed a low dispersal ability for D. suzukii, with a daily flight distance below 100 m with no predominant wind. The implications on natural dispersion and control methods based on attractants are discussed.This research received funding from the European Union's Seventh Framework Programme for research, technological development and demonstration under grant agreement no 613678 (DROPSA).Vacas, S.; Primo Millo, J.; Manclus Ciscar, JJ.; Montoya, Á.; Navarro-Llopis, V.

Adaptación de la docencia en el cálculo de estructuras a las nuevas tecnologías

La implantación de las nuevas metodologías de enseñanza a partir de las directrices establecidas en el Espacio Europeo de Educación Superior, ha supuesto una renovación necesaria en los materiales docentes utilizados. En este sentido, el presente artículo muestra los avances en el uso de programas informáticos para la resolución de estructuras desarrollado a lo largo de las diferentes asignaturas que conforman las titulaciones de Ingeniería Civil, el Máster de Caminos, Canales, y Puertos, así como el Máster de Ingeniería de los Materiales, Agua y Terreno de la Universidad de Alicante. De esta forma el alumno es capaz de aproximarse a la realidad laboral, pudiendo comparar los resultados analíticos resueltos de forma tradicional, con los obtenidos con software comerciales ampliamente extendidos en el campo profesional. El uso de dichas herramientas se ha introducido de forma progresiva a lo largo de todos los cursos de las titulaciones anteriormente comentadas. Inicialmente, el alumno se familiariza con la resolución de estructuras a través de elementos barra, combinando diferentes materiales y acciones. Finalmente, el alumno desarrolla elementos placa, así como modelos reológicos y análisis dinámicos de estructuras. Por este motivo, y con el fin de completar la educación de los alumnos, en el presente trabajo se ha tratado de aproximar al alumno a las estructuras reales y a su posterior modelización numérica
