Las asociaciones juveniles de Tusculum (Lacio, Italia): la evidencia epigráfica

Il presente lavoro analizza la documentazione epigrafica relativa alle associazioni dei giovani dalla città di Tusculum, dove è conosciuta tanto la presenza di un gruppo maschile, i sodales lusus iuvenalis, come quello femminile, molto visibile peraltro, in cui le donne vengono chiamate sodales iuvenum. Questo gruppo fu onorato con dei monumenti pubblici nel centro della città.This paper examines the role displayed by associations of the youth in Tusculum. The epigraphic evidence allows to recognize two groups: the male one, named sodales lusus iuvenalis and the female one, the sodales iuvenum, which was honoured with public monuments.Ce travail étudie la documentation épigraphique sur les associations des jeunes de la ville de Tusculum. Il existe des preuves d’un groupe masculin, les sodales lusus iuvenalis, mais aussi d’un autre group féminin, très visible, appelé sodales iuvenum, honoré avec des monuments publics dans le centre-ville

Press counterweight of a torcularium with a latin inscription from the Los Palacios' roman archaeological site (Villanueva del Pardillo, Madrid)

Presentamos una nueva inscripción reutilizada como contrapeso de un torcularium en el yacimiento romano de Los Palacios (Madrid). A pesar del mal estado de conservación del texto, su lectura ha podido ser realizada en parte gracias a la ayuda de modernas técnicas de fotogrametría. El bloque tiene un paralelo directo tanto de soporte como del tipo de contenido en otra pieza de la localidad de Villamanta. De acuerdo con nuestra lectura, ambas inscripciones corresponden a epitafios de miembros de la gens Aelia, lo que junto a parámetros formales semejantes, permiten plantear una procedencia común para ambas piezas.A new Latin inscription, reused as counterweight of a torcularium in the Roman site of Los Palacios (Madrid), is presented. Although the corrupt condition of the text, the reading was partially made thanks to current photogrammetric technics. There is another inscription from Villamanta, which seems to be a direct parallel as well in shape as in contents. According to our reading, both are epitaphs of members of the gens Aelia and, in addition, there are some formal parameters that allow suggesting a shared origi

Virgilio, Ovidio y, quizá, Valerio Flaco en un nuevo fragmento de inscripción romana procedente de Tarraco

Presentamos un nuevo fragmento de inscripción funeraria procedente de la antigua Tarraco con parte de un carmen epigraphicum en hexámetros dactílicos. A pesar del poco texto conservado, el contenido permite identificar un centón a partir del repertorio poético de Virgilio y Ovidio, y quizá también de Valerio Flaco

Rescatando a Baiter: A propósito de la origo de Marco Celio Rufo (Cic. Cael. 5)

El objetivo del texto es recuperar la intuición de Johan Georg Baiter (1801-­1877) que propuso Tusculum (Lacio, Italia) como patria de origen de Marco Celio Rufo enmendando una corruptela en la edición orelliana del Pro Caelio ciceroniano. Esta conjetura, desestimada en todas las ediciones posteriores del texto, ha sido recientemente confirmada gracias al hallazgo de un epígrafe que documenta por vez primera en la ciudad lacial un magistrado M. Caelius de época tardorepublicana

The Flavian Officina Lapidaria Tarraconense: colour and texture in the service of Rome

We present a reflection on the workshops charged with shaping the public image of Flavian Tarraco through its epigraphic monuments. For this purpose, we undertooka detailed analysis of the materials and media used to decorate the areas of representation of the Concilium Provinciae, established at the beginning of Vespasian’s reign, contrasting them with the epigraphic production of the preceding periods. The study is compared to other archaeological relics from the same area.  We present a reflection on the workshops charged with shaping the public image of Flavian Tarraco through its epigraphic monuments.

Una etiqueta de plomo con fitónimos procedente de Mas Vell : (Vallmoll, ager Tarraconensis)

Presentación de una nueva etiqueta de plomo hallada casualmente en una zona rural del ager Tarraconensis. La pieza presenta dos líneas de texto en las que se ha podido reconocer la presencia de dos fitónimos. La placa está provista de un apéndice lateral en el que se sitúa el agujero para el hilo o cuerda que la unía a la vasija o contenedor. Este elemento resulta muy poco usual en este tipo de documentos epigráficos.A new lead label has been found by chance in a rural area of the ager Tarraconensis. The piece has two writing lines with two plant names. The plate is provided with a lateral appendix with a hole for the filament that connected it to the vessel or box. This element is very unusual in this type of epigraphic documents

Super-heavy fermion material as metallic refrigerant for adiabatic demagnetization cooling

Low-temperature refrigeration is of crucial importance in fundamental research of condensed matter physics, as the investigations of fascinating quantum phenomena, such as superconductivity, superfluidity and quantum criticality, often require refrigeration down to very low temperatures. Currently, cryogenic refrigerators with $^3$He gas are widely used for cooling below 1 Kelvin. However, usage of the gas is being increasingly difficult due to the current world-wide shortage. Therefore, it is important to consider alternative methods of refrigeration. Here, we show that a new type of refrigerant, super-heavy electron metal, YbCo$_2$Zn$_{20}$, can be used for adiabatic demagnetization refrigeration, which does not require 3He gas. A number of advantages includes much better metallic thermal conductivity compared to the conventional insulating refrigerants. We also demonstrate that the cooling performance is optimized in Yb$_{1-x}$Sc$_x$Co$_2$Zn$_{20}$ by partial Sc substitution with $x\sim$0.19. The substitution induces chemical pressure which drives the materials close to a zero-field quantum critical point. This leads to an additional enhancement of the magnetocaloric effect in low fields and low temperatures enabling final temperatures well below 100 mK. Such performance has up to now been restricted to insulators. Since nearly a century the same principle of using local magnetic moments has been applied for adiabatic demagnetization cooling. This study opens new possibilities of using itinerant magnetic moments for the cryogen-free refrigeration
