Abstract: Although he is the most prolific writer of the Greek Anthology, Palladas’ life is almost unknown. But, in spite of the limited biographical data, his work has fortunately been preserved in the GA. Because of his literary creation, the old times rewarded him with the nickname Μετέωρος, high, since the literary merits of a hundred poems of his authorship was recognized (others are discussed by critics). A dozen of them contains invaluable information about the political, religious and social situation in Alexandria immediately after the victory of the bishop Theophilus, Cyril’s predecessor and uncle, during the conflict between Christians and Gentiles, each sector backed up by an Alexandrian population segment (cfr. 9.528, 10.82, 10.85) . Resigned at times, constantly demanding, Palladas complains about the decline of the belief professed by him due to the increasing penetration of the new faith. Therefore, four epigrams record the conversion of the temple of Tyche into a tavern (9.180-183) and 10.90 seems to attack the doctrine of the Resurrection. When religion and politics go hand-in-hand, when religious conspiracies link up with palace intrigues, consequences are predictable: a man called Doroteo denounced him for his negative response to the new dogma, which caused him the loss of his teacher paid work. His annoyance was even greater with further sufferings, chiefly economic, and he had to sell his books (9.171 and 9.175) among other desperate decisions Forewarned about his radical bitterness against Church, it is just to make clear that he is not fully acquiescent with ancient gods and heroes. Thus, in 5.257 he questions Zeus’ ars amandi, in 9.377 refutes Tantalus’ possibility of thirst and hunger in Hades and 9.773 mischievously points out that Eros has been changed into a pan. The work begins with the selection, personal translation and comprehensive analysis of twenty two epigrams. Through such philological aid, we attempt to verify the frictions and the main perceptible factors in his poetic creation to justify his worldview, according to the pagan sentiment widespread in that time before the twilight already overwhelming of its ailing traditions

Abstract: In this article I want to show the negotiations of the Emperor Julian about recruitment and Anonna Militaris. 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

Sebastião Pacheco Varella nasceu em Aveiro, Portuga em 1671 e morreu na mesma cidade , em 170 6. Notável pregador e muito hábil nas línguas latina, espanhola, francesa e italiana, o autor publicou ‘Numero vocal’. O ‘Sermão da seráfica Madre Santa Teresa, na manhã da sua festa, pregado em Aveiro no ano de 1700’, em Coimbra, em 1701; ‘Sermão da seráfica Madre Santa Teresa, na tarde da sua festa, pregado em Aveiro, no dito anno’, em Coimbra, em 1701; e ‘Sermão da bem-aventuraria Santa Joana, Princesa de Portugal e Senhora de Aveiro, pregado no mosteiro da mesma vila em que viveu e morreu na ultima tarde do seu tríduo’, em Lisboa, em 1702. Essa edição é a primeira da obra, que é um conjunto de princípios inspirados na fé católica e no exemplo de São João Batista, como objetivo de orientar os monarcas católicos em suas ações. Segundo Inocêncio, ‘Varella reúne em seu favor os votos de alguns críticos ilustrados’. Morais o "cita" no Dicionário muitas vezes, autorizando com ele o uso de vários termos, e o P. Francisco José Freyre não duvidou qualificá-lo de autor de bastante propriedade na locução e de linguagem corrente’

Part I: The mobilities of photo-generated electrons and holes in orthorhombic sulfur are determined by drift mobility techniques. At room temperature electron mobilities between 0.4 cm2/V-sec and 4.8 cm2/V-sec and hole mobilities of about 5.0 cm2/V-sec are reported. The temperature dependence of the electron mobility is attributed to a level of traps whose effective depth is about 0.12 eV. This value is further supported by both the voltage dependence of the space-charge-limited, D.C. photocurrents and the photocurrent versus photon energy measurements.
As the field is increased from 10 kV/cm to 30 kV/cm a second mechanism for electron transport becomes appreciable and eventually dominates. Evidence that this is due to impurity band conduction at an appreciably lower mobility (4.10-4 cm2/V-sec) is presented. No low mobility hole current could be detected. When fields exceeding 30 kV/cm for electron transport and 35 kV/cm for hole transport are applied, avalanche phenomena are observed. The results obtained are consistent with recent energy gap studies in sulfur.
The theory of the transport of photo-generated carriers is modified to include the case of appreciable thermos-regeneration from the traps in one transit time.
Part II: An explicit formula for the electric field E necessary to accelerate an electron to a steady-state velocity v in a polarizable crystal at arbitrary temperature is determined via two methods utilizing Feynman Path Integrals. No approximation is made regarding the magnitude of the velocity or the strength of the field. However, the actual electron-lattice Coulombic interaction is approximated by a distribution of harmonic oscillator potentials. One may be able to find the “best possible” distribution of oscillators using a variational principle, but we have not been able to find the expected criterion. However, our result is relatively insensitive to the actual distribution of oscillators used, and our E-v relationship exhibits the physical behavior expected for the polaron. Threshold fields for ejecting the electron for the polaron state are calculated for several substances using numerical results for a simple oscillator distribution.

Methods for the estimation of zooplankton biomasses, used in the Oceanographic Research Center of Abidjan are presented. They deal with settled and displacement volumes, dry weight and ash-free dry weight, elementary carbon, nitrogen and phosphorus composition. The dry weight method is detailed: elimination of salt by a fresh water stream, preservation of dry samples at -20 degrees Celsius, rehydration during weighing. A few comments on the 'CHN' analysed values are made: at 1,100 degrees Celsius, most of the carbon is organic, only 10% of the mineral fraction being analysed.

[ES] Se analiza un sestercio de Nerón usado como elemento ornamental. Un artesano hizo en el reverso de la moneda algunos radios curvos y cinco agujeros. En el artículo se hacen una serie de consideraciones sobre la realización de este inusual trabajo y su posible función. Por otro lado, también se examinan ciertos aspectos de los usos ornamentales de la moneda y la evaluación moral de la figura de Nerón.

This paper describes how the A -if) formulation may be applied to determine the losses in the stator duct spacers of large a.c. motors. The model is described in terms of its geometry and boundary conditions. The novel aspects of the application of the formulation to this problem are explained. These include the modelling of fixed currents sources (the stator windings), the location of the necessary cut surfaces and the determination of their magnetic scalar potential differences, and the implementation of periodic boundary conditions for vector variables. Results are presented showing how the duct spacer losses vary with load, and with the relative permeability of the spacer material. The effects of modelling iron nonlinearity, of both the spacer and the steel laminations, are also illustrated. © 1996 IEEE.
