Los ludi en la Roma arcaica

Resumen: En este artículo se analizan los juegos públicos celebrados en Roma durante el período monárquico. Su creación obedece a motivos religiosos, en relación a la fecundidad (Consualia, ludi Taurei) o a la guerra (Equirria, equus October). La culminación religiosa y política de los juegos se materializa en los ludi Romani, institutidos por el rey Tarquinio Prisco. Finalmente es considerado también el llamado lusus Troiae, juego ecuestre exclusivo de los jóvenes y asimismo de origen arcaico.

El miedo en la guerra griega antigua y su conceptualización en las fuentes : una introducción

Abstract: Fear is commonly regarded as a natural emotion in war, present as well in ancient Greek warfare. Greek literary sources occasionally emphasize the emotions connected to the contemporary experience of combat from a primarily narrative perspective. This paper will offer an introduction to the Greek notion and conceptualization of fear in the classical period and its relationship with war, intending to achieve a better understanding of its role in the literary sources and, ultimately, its relevance in Greek culture and warfare.

I'm trying to develop some ideas on Julian's Military History during his time as a Cesar of Constantius II and as an Emperor. We are joying some arguments to understand his preparation for the military life

Na trilha do etéreo : a divinizaçao da Domus Iulia na Eneida de Vigílio e nas Metamorfoses de Ovídio

Resumen: No momento em que a Eneida foi composta, entre os anos 29 e 19 a.C, a memória da divinização de César se fazia presente, lançando também a expectativa sobre a consecratio do próprio Imperador. No poema épico, o prenúncio da apoteose de Augusto surge na mesma profecia em que Júpiter assegura a Vênus a acolhida de seu filho, Enéias, entre os imortais (VIRGÍLIO, Eneida, I.259- 289). Este tema reaparece nas Metamorfoses de Ovídio cujas linhas finais do livro XV retratam a transformação de Júlio César em astro – sidus - e mencionam o dia em que o Princeps deverá receber, nos céus, as preces de seus governados (OVÍDIO, Metamorfoses, XV.745-879). Tendo em vista a instituição do culto imperial, problematizaremos nas obras mencionadas as relações entre mito, memória e poder no Principado.

Identidad y memoria como principio de legitimación : el caso de la construcción del poder imperial de Séptimo Severo

Abstract: I will focus on the Roman Empire during the final years of the 2nd century A.D., which are considered by Classical Historiography as critical. This epithet is based on the detection of estructural and circumstancial changes linked to state power’s concept. Emperor Pertinax’s murder in 193 can be understood as the trigger of the civil war extended up to the year 197. During those years the tutelary of state power was jeopardized, when four Emperors were crowned at the same time. By the time this struggle ended, Lucius Septimius Severus was recognized as the victorious general and the first of his name in the new dynastic line. Considering these facts, it is the purpose of my work to analize the rising figure of Septimius Severus, from civil war’s clashing context through which the Emperial legitimacy had to be set.

Micromechanics analyses of interface crack

A new mechanics model based on Peierls concept is presented in this paper, which can clearly characterize the intrinsic features near a tip of an interfacial crack. The stress and displacement fields are calculated under general combined tensile and shear loadings. The near tip stress fields show some oscillatory behaviors but without any singularity and the crack faces open completely without any overlapping when remote tensile loading is comparable with remote shear loading. A fracture criterion for predicting interface toughness has been also proposed, which takes into account for the shielding effects of emitted dislocations. The theoretical toughness curve gives excellent prediction, as compared with the existing experiment data.

Reference-growth rate – a simple and handy parameter summarizing the influence of environmental conditions

Abstract Environmental changes may have an impact on life conditions of the fish, e.g. food supply for the fish. The prevailing environmental conditions apply evenly to all age groups of one stock. Small fish have high growth rates, whereas large fish grow with low rates. But, it can be shown on the basis of the von Bertalanffy-growth model that it is sufficient to know only the growth rate of one single age group to compute the growth rates of all other age groups. The growth rate of a reference fish GRF (e.g. a fish with a body mass of 1 kg) was introduced as a reference growth describing the current food condition of all age groups of the stock. As an example a time series of the reference-growth rate of the northern cod stock (NAFO, 3K) was computed for the time span 1979 to 1999. For the northern cod stock it can be observed that environmental conditions caused growth rates below the long-term mean for seven years in a row. After a prolonged hunger period the fish stock collapsed in 1992 also by the impact of fisheries - and this was probably not a coincidence. Now, with the reference-growth rate GRF a simple and handy parameter was found to summarize the influence of the environmental conditions on growth and other derived models and therefore makes it easier to compute the influence of environmental changes within stock assessment. Zusammenfassung Veränderungen der Umwelt können Auswirkungen auf die Lebensbedingungen der Fische haben, z. B. auf das Nahrungsangebot der Fische. Die vorherrschenden Umgebungsbedingungen wirken gleichmäßig auf alle Altersgruppen eines Bestandes, wobei typischer Weise kleineFische hohe Wachstumsraten haben, während die großen Fische mit niedrigen Raten wachsen. Auf der Grundlage des von Bertalanffy-Wachstumsmodells kann gezeigt werden, dass es ausreicht, nur die Wachstumsrate von einer einzigen Altersgruppe zu kennen, um die Wachstumsraten von allen anderen Altersgruppen berechnen zu können. Die Wachstumsrate eines Referenz-Fisches (z.B. eines Fisches mit einer Körpermasse von 1 kg) wurde als Referenz-Wachstum GRF eingeführt, die den aktuellen Zustand des Nahrungsangebots füralle Altersgruppen des Bestandes beschreibt. Als Beispiel wurde einer Zeitreihe der Referenz-Wachstumsraten des nördlichen Kabeljaubestandes (NAFO, 3K) für die Zeitsraum 1979 bis 1999 berechnet. Für diesen Kabeljaubestand war zu beobachten, dass Umgebungsbedingungen für sieben Jahre in Folge Wachstumsraten unter dem langjährigen Mittelwert verursachten. Nach einer längeren Hungerperiode kollabierte dieser Fischbestand im Jahr 1992 auch durch den Einfluß der Fischerei - und dies war sicher kein Zufall. Jetzt, mit der Referenz-Wachstumsrate GRF, ist ein einfacher und handlicher Parameter gefunden, der es gestattet den Einfluss der Umweltbedingungen auf die Wachstumsbedingungen und andere davon abgeleitete Modelle zusammenzufassen. Dies macht es einfach, den Einfluss von Umweltveränderungen innerhalb der Bestandsabschätzungen zu berechnen.

Low-loss planar and stripe waveguides in Nd3+-doped silicate glass produced by oxygen-ion implantation

We report on the fabrication and characterization of low-loss planar and stripe waveguides in a Nd3+-doped glass by 6 MeV oxygen-ion implantation at a dose of 1x10(15) ions/cm(2). The dark mode spectroscopy of the planar waveguide was measured using a prism coupling arrangement. The refractive index profile of the planar waveguide was reconstructed from a code based on the reflectivity calculation method. The results indicate that a refractive index enhanced region as well as an optical barrier have been created after the ion beam processing. The near-field mode profiles of the stripe waveguide were obtained by an end-fire coupling arrangement, by which three quasitransverse electric modes were observed. After annealing, the propagation losses of the planar and stripe waveguides were reduced to be similar to 0.5 and similar to 1.8 dB/cm, respectively. (c) 2007 American Institute of Physics.

磁控溅射不同厚度银膜的微结构及其光学常数

Ag films with different thickness from 8.2nm to 107.2nm were prepared by DC sputtering deposition and analyzed by X-ray diffraction with the help of optimization program on computer. Microstructrue analysis shows that the films are made of fcc-Ag particles. With the increase of thickness, the mean size of Ag particles increases and the interplaner spacing decreases gradually. The optical constants computed by computer program shows that n value decreases quickly with the increasing thickness below 17.5nm and k value changes in reverse, and then go steadily when the thickness is larger than 17.5nm at the wavelength of 550mn.

En torno a algunas escenas pictóricas de caza del repertorio artístico del SE del Sahara Occidental

[ES] Se describen 4 escenas artísticas con significación cinegética conservadas en otros tantos abrigos situados al SE del Sahara Occidental. Se han reconocido directamente sobre el terreno en el marco del proyecto de investigación sistemática que, desde 2005, llevamos a cabo en la región saharaui del Tiris. Configuran un conjunto de representaciones pictóricas en las que uno o varios individuos se muestran en actitud de cazar uno o varios animales. Tras la valoración analítica del gesto temático, se propone una ordenación cronoestilística para la serie.
