Ultimate Shear of RC Beams with Corroded Stirrups and Strengthened with FRP
2019
Transverse reinforcement plays a key role in the response behavior of reinforced concrete beams. Therefore, corrosion of steel stirrups may change the failure mode of elements from bending to shear, leading to a brittle and catastrophic crisis. It is important to strengthen reinforced concrete beams with corroded stirrups to enhance the shear resistance. This paper presents a formulation, based on the modified compression field theory, to estimate the ultimate shear of reinforced concrete beams strengthened with FRP, because of stirrup corrosion. The detrimental effect of corrosion on steel stirrup yield strength was taken into account by introducing an empirical decay law. The effective st…
Tower sets and other configurations with the Cohen-Macaulay property
2014
Abstract Some well-known arithmetically Cohen–Macaulay configurations of linear varieties in P r as k-configurations, partial intersections and star configurations are generalized by introducing tower schemes. Tower schemes are reduced schemes that are a finite union of linear varieties whose support set is a suitable finite subset of Z + c called tower set. We prove that the tower schemes are arithmetically Cohen–Macaulay and we compute their Hilbert function in terms of their support. Afterwards, since even in codimension 2 not every arithmetically Cohen–Macaulay squarefree monomial ideal is the ideal of a tower scheme, we slightly extend this notion by defining generalized tower schemes …
La costruzione del concetto di omologia e i vincoli materiali della forma
2016
Il concetto di omologia riveste un ruolo centrale nella biologia teoretica contemporanea perché attorno ad esso e per suo tramite trovano articolazione numerosi progetti di ricerca miranti a ripensare la centralità dell’organismo, i suoi percorsi evolutivi e il significato della sua interazione con la realtà ambientale. La rete di omologie che tesse l’organismo permette di strutturarne e canalizzarne le innovazioni morfologiche e funzionali. Appunto questa componente sistemica rende dunque l’omologia un concetto fondamentale per una considerazione dinamica della forma vivente, come quella cui mira un’estetica che non intenda limitarsi a indagare sull’atteggiamento estetico e sulle produzion…
An investigation of Facebook users' implicit associations between Facebook, sexual and prosocial behavior.
2018
Abstract Despite growing research on online social networking, implicit associations of Facebook users have been largely understudied. In Study 1, we used the Single-Target Implicit Association Test (ST-IAT; Karpinski and Steinman, 2006) in order to assess implicit associations between Facebook and two evolutionary relevant constructs: sexual and prosocial behavior. Additionally, we controlled for the role of participant's relationship status as a potential moderator of Facebook implicit associations. In Study 2, we extended these findings and explored the relationship between implicit and explicit associations towards Facebook. Across two studies, we found that Facebook is more strongly as…
Studying students ́satisfaction at music schools in the Valencian Region
2017
[EN] Satisfaction is a key construct but complex to be measured. Within the cultural context and from the discipline of marketing, satisfaction consists of assessing some experiences without considering consumers ́ expectations. From this approach, this paper deals with an empirical research aiming at analyzing satisfaction among students of music conservatoires and schools. The research, qualitative and quantitative in nature, allowed to know users ́ assessment of different variables: studies, teaching staff, information technologies, premises and administration procedures. To do so, a self-administered survey was conducted using a structured questionnaire. Univariate and multivariate anal…
MEMORIZING SONG LYRICS IN PRIMARY EDUCATION DURING THE MUSIC LESSON
2020
Aim. The aim of the study is to identify what techniques students use to memorise song lyrics, how much time is needed to do that, and whether and in what way their parents help them learn the song. The theoretical part of the study analyses previous researches on memorisation in the context of general psychology, age-related psychology, and music psychology.
 Method. The empirical study involved 47 (N=47) second-grade students of the comprehensive school (25 girls and 22 boys). Three study questions are raised in this paper: what techniques do students use to learn how to memorise song lyrics? How much time does a student need to learn singing a song by heart? Do parents help students…
Pandemic H1N1 influenza-associated myocarditis in a patient with Castleman's disease.
2013
We report on a patient with longstanding multicentric Castleman’s disease, hyaline-vascular type, who presented with nearly-fatal myocarditis associated with a 2009 pandemic H1N1 influenza virus infection. This is the first case of such an association described in the literature.
Increased immunosuppressive function of CD4(+)CD25(+)Foxp3(+)GITR+ T regulatory cells from NFATc2((-/-)) mice controls allergen-induced experimental …
2012
The expansion of effector T cells is tightly controlled by transcription factors like nuclear factor of activated T cells (NFAT) family members that mediate early intracellular responses to T cell receptor-mediated signals. In this study we show that, after allergen challenge, NFATc2((-/-)) mice had augmented number of functionally intact CD4(+)CD25(++)GITR(++) T regulatory (T regs) cells in the lung. Anti-GITR antibody treatment inhibited T regulatory cell function and enhanced the number of activated lung CD4(+) T cells associated with increased IL-2 and pSTAT-5 in the airways of NFATc2((-/-)) mice in experimental allergic asthma. This agonistic treatment led to increased inflammation in …
Identidad contra identidades: el destino contra Babelia
1997
El impulso de los nacionalismos y la constatación de la crisis ecológica global, son fenómenos paradójicos y contradictorios. En base a las contribuciones desde la sociología de Eisenstadt y Geisen, y desde el derecho y la teoría política de Wendt y Falk, nosotros argumentamos que el concepto de identidad planetaria, al tiempo que se opone conceptualmente al babelismo nacionalista dominante en ciertos sectores intelectuales, puede cimentar las bases para un entendimiento racional del devenir en este fin de siglo. Nationalism and environmental global conscience are contradictory ideas. We argue in this paper, using as a source from the sociological point of view the work of Eisenstadt and Gi…
Análisis de la interacciones parásito-hospedador en el modelo Echinostoma caproni-roedor, con énfasis en los factores que determinan el curso de la i…
2015
En la presente Tesis Doctoral se analizan diferentes parámetros implicados en las relaciones parásito-hospedador en helmintiasis intestinales mediante la utilización del modelo experimental Echinostoma caproni-roedor. Con esta finalidad se estudian diversos aspectos inmunológicos, además de las alteraciones intestinales inducidas por la infección en dos sistemas parásito-hospedador: E. caproni-ratón y E. caproni-rata. Los resultados obtenidos ponen de manifiesto que el IFN-γ y el óxido nítrico son mediadores fundamentales en el desarrollo de infecciones crónicas en ratón, induciendo disfunción mitocondrial en las células del epitelio intestinal e hiperplasia tisular. No obstante, se sugiere…
