Experimental evaluation of shear and compression strength of masonry wall before and after reinforcement: Deep repointing

Masonry presents some inadequacies due to its almost total lack of tensile strength. Typical damage to multiple leaf walls during earthquakes is the loss of bond between the leaves with consequent collapse of the external leaf. Retrofitting or repair of this damage is a very difficult task. In many cases grout injection or wall jacketing fail due to incompatibility with the construction technique of the walls. A complementary technique to the grouting has been proposed by the authors. Experimental results and applications of the technique on site have shown positive characteristics and the results of tests carried out on site show, in some cases, increases in shear strength and stiffness of the masonry walls

Barreras a la emigración en el final del milenio

[ES] Tras explicar brevemente el proceso de constitucionalización de la extranjería, se mencionan los condicionamientos de tipo normativo y de carácter administrativo a los que ha sido sometido el cuadro constitucional europeo en esta materia a través de la legislación ordinaria de cada Estado. Asimismo, se analiza la imagen del inmigrante en los medios, para finalizar con algunas reflexiones sobre los controles y barreras instrumentales de la inmigración, deteniéndose en el Grupo de Trevi y Schengen.[EU] Atzerritar konstituzionalizatze prozesua azaldu ondoren, europear koadro konstituzionalak estatu bakoitzeko legepideen bidez, gai honetan jasan dituen arau baldintzak eta administratiboak azaltzen dira. Horrez gain, inmigrantearen irudia aztertzen da, inmigrazioaren barrera instrumental eta kontrolei buruz hitzeginez amaitzeko, trevi taldea eta Schengen-ei erreferentzia eginez.[FR] Après avoir expliqué le procès de constitutionnalisation de l’extranéité, on comment les conditionnements normatifs et administratifs qu’a subi le cadre constitutionnel européen en cette matière à cause de la législation ordinaire de chaque État. De même, on analyse l’image d’immigrant dans les moyens de communications, pour finir avec quelques réflexions sur les contrôles et barrières instrumentaux de l’immigration, en s’arrêtant sur le Groupe de Trevi et Schengen.[EN] After explaining briefly the constitutionalization process of the the foreignness, the administrative and legal limitations that the european constitutional frame suffers in this matter through the ordinary legislation of each State are mentioned. Likewise, the immigrant’s image in the medium is anayized, and some reflections about the controls and instrumental barriers of the immigration are expounded, as well as the Groups of Trevi and Schengen

Nutritional benefits of microalga oil replacement in tilapia farming

Schizochytrium oil is currently the only commercially available microalgae oil to replace plant and fish oils in Nile tilapia diets, however there are some uncertainties on its benefits and optimal replacement level. To systematically evaluate the benefits of Schizochytrium in fish nutrition, a metanalysis was conducted. Its results indicated that an inclusion of Schizochytrium did not result in loss of omega-3 content of the fish fillet (SMD = 0.62; 95%CI = -0.51-1.76). To assess the effects on survival and changes in the gut microbiota (16S rRNA sequencing) of Nile tilapia, Schizochytrium oil was incorporated in the fish diet. Microalgae-oil in the diet increased growth rate without impacting on fish survival. Plant oil caused an increase in the abundance of Aeromonadaceae in the gut, but this was not the case with microalgae oil was used. To characterize the long-term effects of microalgae oil, Nile tilapia from the previous experiment were fed on the same diets for 11 months. Schizochytrium oil in the diet increased the omega-3 content of the Nile tilapia fillet up to 32.30±1.13%. The benefits of Schizochytrium oil replacement was also tested on Manyara tilapia (Oreochromis amphimelas), an endangered species. Schizochytrium oil increased fish growth and omega-3 content of the flesh up to 32.68±0.25%. Gonad development was not affected by Schizochytrium oil in the diet. The results of this thesis indicate, that Schizochytrium oil can replace fish-based oils in the diet of Nile tilapia without compromising survival or disrupting the composition of the gut-microbiome as plant-based diets do, whileat the same time improving growth and omega-3 content of the fillet in both Nile and Manyara tilapia thus representing a better alternative to fish oils than plant-based oils
