Diabolè: The Personal Attack in Ancient Greek Rhetoric

2014

The topic of this article is the concept of diabole (personal attack) in ancient Greek rhetoric. I intend to show the ambivalent attitude of Greek oratory and rhet-oric toward this phenomenon; ambivalent because although diabole is depicted as a public danger, it is regularly adopted. My hypothesis is that this ambivalence de-pends on the intrinsic ambiguity of the concept of diabole itself. I believe that this ambiguity is strictly connected to the intrinsic competitiveness of public debate and that this competitiveness is a dynamic factor that cannot be eliminated. Therefore, despite its dangers, diabole still remains a risk that cannot be avoided. For this rea-son, a survey of this notio…

Diagrammatic Gestures. Cognition, Mathematics, and Semiotics.

2021

here are words having an extraordinary evocative power. This is precisely the case of “Diagram” and “Gesture”. The frst term covers an interconnected network of concepts like “graph”, “schema”, “form”, “model”, “arrow”, and so on... And the same can be said of the second one: just think, for example, of the ideas of “movement”, “bodily action”, “practical activity” or, more generally, of “doing”. Accounting for them has been, over the last 50 years, the aim of signifcant portions of the work conduction in philosophy (Deleuze, Foucault, Merleau-Ponty), mathematics (Grothendieck, Lawvere, Thom), semiotics (Peirce), and theoretical linguistics (Culioli, Langacker, Pottier). The present issue a…

ASSESMENT OF TEMPERATURE POLARIZATION IN MEMBRANE DISTILLATION CHANNELS BY LIQUID CRYSTAL THERMOGRAPHY

2014

AbstractThe measurement of local temperature distributions within a membrane distillation (MD) channel is a crucial step for the optimization of the channel and spacer geometry. This information allows the estimation of temperature polarization phenomena, which can dramatically influence the thermal efficiency of the process and the optimal choice of the geometric configuration (net spacer features, channel size, etc.). In the present work, a recently presented experimental technique, based on the use of thermochromic liquid crystals and digital image analysis, has been employed in order to assess the temperature polarization phenomena. The local heat transfer coefficient distribution on th…

El origen de los trastornos mentales: un nuevo enfoque desde el estudio de la dinámica de la personalidad

2018

[EN] There is a growing consensus in the mental health sciences (psychology, psychiatry) that there is no clear dividing line between "normal" personality and "abnormal" personality or mental disorders. In fact, basic personality traits predispose or overlap with clinical mental disorders. For example, Neuroticism, as a factor that predisposes to neurosis, predisposes to suffer from anxiety, depression and obsessive disorders. This question serves to present a summary of the work of our group (Antonio Caselles, Joan C. Micó and Salvador Amigó) and to point out future research. Thus, after reviewing our studies on the dynamics of the General Personality Factor (FGP) and its biological substr…

Radó-Kneser-Choquet Theorem for simply connected domains (p-harmonic setting)

2018

A remarkable result known as Rad´o-Kneser-Choquet theorem asserts that the harmonic extension of a homeomorphism of the boundary of a Jordan domain ⌦ ⇢ R2 onto the boundary of a convex domain Q ⇢ R2 takes ⌦ di↵eomorphically onto Q . Numerous extensions of this result for linear and nonlinear elliptic PDEs are known, but only when ⌦ is a Jordan domain or, if not, under additional assumptions on the boundary map. On the other hand, the newly developed theory of Sobolev mappings between Euclidean domains and Riemannian manifolds demands to extend this theorem to the setting on simply connected domains. This is the primary goal of our article. The class of the p -harmonic equations is wide enou…

A note on a result of Guo and Isaacs about p-supersolubility of finite groups

2016

In this note, global information about a finite group is obtained by assuming that certain subgroups of some given order are S-semipermutable. Recall that a subgroup H of a finite group G is said to be S-semipermutable if H permutes with all Sylow subgroups of G of order coprime to . We prove that for a fixed prime p, a given Sylow p-subgroup P of a finite group G, and a power d of p dividing such that , if is S-semipermutable in for all normal subgroups H of P with , then either G is p-supersoluble or else . This extends the main result of Guo and Isaacs in (Arch. Math. 105:215-222 2015). We derive some theorems that extend some known results concerning S-semipermutable subgroups.

On the supersoluble hypercentre of a finite group

2016

[EN] We give some sufficient conditions for a normal p-subgroup P of a finite group G to have every G-chief factor below it cyclic. The S-permutability of some p-subgroups of O^p(G)plays an important role. Some known results can be reproved and some others appear as corollaries of our main theorems.
