11 Madinat al-Zahra Edificio Basilical Superior 15342
Medina Azahara “Madinat al-Zahra” Carretera de Cordoba a Palma del Río, km. 5,5. Córdoba
La investigación sobre Madinat al-Zahra y el proceso para su recuperación son recientes, las primeras excavaciones se realizan en 1911. En ese periodo, y especialmente bajo la dirección del arquitecto Félix Hernández, se excavó la parte central del Alcázar, con una superficie de unas 10,5 hectáreas, y se definieron las líneas básicas del urbanismo del palacio acometiendo, además, importantes restauraciones como la del Salón de Abd al-Rahman III. En 1985 pasa a depender de la Junta de Andalucía como Conjunto Arqueológico con nuevos instrumentos de protección y gestión. Una ciudad islámica de 112 hectáreas mandada construir, a cargo del maestro alarife Maslama ben Abadía, por el primer califa de al-Andalus, Abd al-Rahman III, en el año 936 ó 940, como residencia personal y sede del gobierno.
Situada entre las faldas de Sierra Morena, al pie de la montaña Yebel al-Arus (“Monte de la Desposada”), y el valle del Guadalquivir, se dispone en terrazas para adaptarse a la pendiente del terreno, la primera de las cuales corresponde a la zona residencial del califa, seguida por la zona oficial, administrativa y jardines..., hasta albergar las viviendas y talleres del pueblo, junto con la mezquita Aljama, en la parte mas baja, separadas de las dos terrazas anteriores por una muralla que las aislar del conjunto palatino. La zona palaciega albergaba las viviendas de los dignatarios más importantes y los órganos administrativos del Estado, que fueron trasladados desde Córdoba. Durante los reinados de Abd al-Rahman III y al-Hakam II, la ciudad se convirtió en la capital de al-Andalus. Entre los años 1010 y 1013, durante la guerra civil que puso fin al califato omeya, se inició su abandono y saqueo, y sus restos se utilizaron como cantera para otras construcciones. Es considerada como una de las cumbres del arte islámico, tanto por su estructura y disposición urbana como por las soluciones arquitectónicas empleadas, la diversidad de sus materiales y la extraordinaria riqueza y calidad decorativa. Frente a la idea laberíntica y caótica característica del urbanismo musulmán, Medina Azahara presenta una planta rectangular de 1500 por 750 metros, con trazado ortogonal, red de alcantarillado y abastecimiento de agua perfectamente planificados. Está considerada la ciudad de nueva planta con mayor superficie construida de una sola vez en el Mediterráneo.
Edificio Basilical Superior
Este gran salón, de mediados del siglo X, debió ser la sede de algún órgano, aún sin determinar, de la administración califal. Edificio basilical de cinco naves separadas por arcadas soportadas por columnas, y una nave transversal que se abre sobre una amplia plaza, no ajardinada en su origen. Conserva prácticamente íntegro su pavimento original de ladrillo. El revestimiento de muros y arcos se realiza combinando mortero pintado de almagra y blanco

As I Am
By Peter S. Quinn
As I am
I am your tender way
Someone to follow
Earth in its gray
Love song of the deep
As hours pass by
Hold on and keep
Knots to lose and try
You are for me
Night with its stars
Someone to follow
Winter’s top isobars
Can’t you hear me singing
Like a bird in a tree
To your heart bringing
Something of me
As I am
Without any taken
Winter ways hollow
Through the darks waken
No one but you
Understands this
From the dim dim blue
Outside in vast abyss

Cathedral from Hyde Park - Australia.
Hyde Park: History
Hyde Park takes its name from a park in London. Hyde Park in London is one of the largest parks in Central London.
Hyde Park began as the city’s first race course and later functioned as a cricket ground for a brief period.
Hyde Park: Features
The most identifiable feature of Hyde Park is the grand Archibald Fountain. The monument was inaugurated in 1932 as a tribute to those Australian soldiers who lost their lives during the Great War in France. Archibald Fountain is regarded as one of the finest public fountains in Australia.
Archibald Fountain
From Wikipedia, the free encyclopedia
Archibald Fountain, Hyde Park, Sydney
The Archibald Fountain, properly called the J.F. Archibald Memorial Fountain, widely regarded as the finest public fountain in Australia, is located in Hyde Park, in central Sydney, New South Wales. It is named after J.F. Archibald, owner and editor of The Bulletin magazine, who bequeathed funds to have it built. Archibald specified that it must be designed by a French artist, both because of his great love of French culture and to commemorate the association of Australia and France in World War I. He imagined its civic design and ornamentation developing to rival his dream city Paris. The artist chosen was Francois Sicard.
The fountain was unveiled on 14 March 1932 by the Lord Mayor of Sydney, Samuel Walder.
------
Sicard was one of the foremost sculptors of his day, a classically educated artist, whose inspiration was derived, at least in part, from his study of classical Greek and Roman art and literature. In submitting his proposal for the design of the sculptural groups, Sicard wrote:" Apollo represents the Arts (Beauty and Light). Apollo holds out his right arm as a sign of protection, and spreads his benefits over all Nature, whilst he holds the Lyre in his left hand. Apollo is the warmth which vivifies, giving life to all Nature. At the touch of his rays, men awake, trees and fields become green, the animals go out into the fields, and men go to work at dawn.
The ancient Pliny adored the sun, symbol of Life. It is on this account that I wished this figure to be the chief one in the memorial.
At Apollo's feet the star of day is indicated by a semicircle, of which the rays spread out in jets of light (the rising sun). The horses' heads represent the horses of Apollo's chariot. Out of their nostrils the water will fall into the first basin, to fall from there into the second, and run away into the large basin.
The large basin is divided into three groups. One represents Diana, goddess of purity, of peaceful nights, symbol of charity; the ideal which watches over mortals - all that stands for poetry and harmony. The second group symbolises the good things of the earth - it is the young god of the fields and pastures, of the pleasure of the countryside. The third group represents sacrifice for the public good. Theseus, vanquisher of the Minotaur. The spirit triumphs over bestiality. Theseus delivers his country from the ransom which it had to pay to this monster. It is the sacrifice of himself for the good of humanity. Between these groups tortoises throw jets of water. The fountain is electrically illuminated and floodlighted at night."
It depicts Apollo, representing beauty and the arts, on a central column holding out his right arm as a sign of protection over all nature. On the three plinths radiating from the central column there are figures representing Diana, the goddess of purity; a group representing the good things of the earth; Theseus slaying a Minotaur, representing the sacrifice for the good of humanity."
Interestingly, Sicard quotes Pliny as one of the ancient Roman sources for the modern understanding of the qualities supposedly represented by the gods. Rather than merely using the visual examples of works such as those by Pheidias, the iconic sculptor of classical Athens, whose free standing and frieze statuary represent the acme of the classical depiction of the human form in larger-than life bronze or marble, Sicard used literary sources to explain the symbology behind the form.
His choice of classical figures was in keeping with the European tradition of the sculpture and architecture of the precinct of Hyde Park. There is no indication in the writings of Sicard, or indeed, in the appraisal of his work, that there was any intention to link the figures in the sculptural groups with any religious or sexual themes.
Over the years the Archibald Fountain has been a chosen spot for photos, buskers, political rallies and just as a meeting place. Park benches are provided nearby, making it a popular location for city workers at lunchtime.
An imposing stone structure of decorated geometrical Gothic design, with twin towers above its main southern entrance, rises along the northeastern side of Hyde Park in the heart of Sydney. This is one of the more notable and historic Sydney churches, a Sydney landmark.
St Mary's Cathedral, whose foundation stone was laid by Archbishop Bede Polding in 1868, rises from the site of the first Sydney cathedral built earlier in the century but which had gone up in flames in 1865.
It is the mother church of Australian Catholicism.
St Mary's Cathedral lies in an area bounded by Hyde Park and the underground St James station in the west, government buildings in the north, The Domain in the northeast and east, and Cathedral Rd and Phillip Park in the south.
In the heart of the city
Hyde Park, cut into two sections by Park St which leads east to Kings Cross, is almost certainly the very heart of the city of Sydney.
St Mary's Cathedral itself is almost completely surrounded by swards of green.

El publico asistió numeroso .los cortometrajes fueron extraordinarios ,personalmente solo pude ver dos de ellos , que me crearon un gran impacto .
me sigue resultando incompresible el tratamiento de algunas zonas de nuestro planeta hacia otras personas con cualquier excusa , la persecución y los malos tratos siguen siendo frecuentes y de la partida , Ante estos los medios de los que quieren ayudar parecen en ciertos casos bien derisorios ,pero su persistencia da frutos . Romper la indiferencia de los que tiene el privilegio de vivir en sociedades mas estables y de sus responsables socio políticos
es ya una manera de ayudar estos cortometrajes ciertamente abren la puertas a esa conciencia tan necesaria para frenar los abusos que se pasean
impertérritos hacia ciertas personas o grupos étnicos, religiosos... en por desgracia tantas partes del mundo .
La exposición destaco por la variedad de trabajos muchos de ellos con un innegable carácter expresionista ,
Al finalizar la inauguración los numeroso voluntarios se pusieron al trabajo para desmontar todo lo necesario al festival de cortometrajes la exposición de arte seguira toda la semana .
Para los próximos años les gustaría poder producir un dvd con los cortometrajes, asi me comentaron los organizadores .

Theodore Fatseas – Writer/Director/Producer
Theo's focus as a documentary filmmaker is to make films that give an in-depth view into people's lives, painting a picture that helps us to understand a little more about who we are, where we've been and where we are going. He established Transition Films in 2006 with "Touching Palestine" as his film debut (currently in post production). He also recently completed a short film, "The Secret Bar" and has started production on a half hour documentary called "60 years and a day in Gaza".
Theo is passionate about building honest and genuine relationships which reflect the honesty and truth in his work. Forever keen to go the extra mile he is dedicated to capturing images that help to tell a compelling story.

Transition to the normal state of superconducting Y1Ba2Cu3O7- δ thin films induced by high current densities
Currás, S. R.; Wagner, P.; Ruibal, M.; Viña, J.; Osorio, M. R.; González, M. T.; Veira, J. A.; Maza, J.; Vidal, F.
Superconductor Science and Technology, Volume 14, Issue 9, pp. 748-753 (2001).
We report measurements at zero applied magnetic field of the characteristic curves (E-J) in Y1Ba2Cu3O7-δ thin films in the high current density regime, up to current densities which induce the transition to the normal state. To minimize spurious heating effects due to Joule dissipation, the E-J curves were measured with a pulse technique and with the samples submerged in a liquid nitrogen bath, changing the temperature by varying the nitrogen vapour pressure. This experimental set-up allows us to observe not only the abrupt voltage jump appearing at current densities J* much larger (typically one order of magnitude) than the critical current density, Jc, but also the entire transition up to the normal state. Our results show that the product J*ρn is roughly sample independent, ρn being the slope of the E-J curves for J>J*. This finding is in qualitative agreement with the existing models that explain the jump at J* in terms of a vortex instability at high flux-flow velocities.

Massa Bouchafa - Amazigh Festival -1
Amazigh is the original name in “Tamazight” language given to the native indigenous people of North Africa, also known as “Berber”. Amazigh means free man. They are distributed from the Atlantic to the Siwa oasis in Egypt, and from the Mediterranean to the Niger River.
Amazigh Association of Australia (AAA) is a newly formed non-political and non-religious community group that seeks to promote the North African native culture in harmony with the people of Australia.
AAA introduces for the first time the Amazigh culture to the Australian society.
