Siege of Bahrain (1529)

Siege of Bahrain (1529)
The Siege of Bahrain in 1529 was a military engagement between the Portuguese and the Bahrainian rebels who revolted against the Kingdom of Hormuz. The siege ended in a fiasco for the Portuguese.
Prelude
The governor of Bahrain, Badr al-Din (Rex Badradim by Portuguese sources), openly revolted against Ormus, this was due to refusing to pay a tribute for the Ormus, who had raised the tribute from 10,000 Ashrafi to 60,000. The Bahrainis also massacred the Portuguese garrison to the last man and hanged the captain from a palm tree. The Ormus king then asked the Portuguese governor of India, Nuno da Cunha for help to subdue the rebels. Nuno answered his call.
Siege
Nuno then dispatched his brother Simao de Cunha with a force of 400 men and 5 ships, they arrived in Bahrain on 20 September, and the rebels had 800 men, Badr al-Din refused to surrender. Simao then began bombarding the fort, however, little damage was done, he kept bombarding it until half of the gunpowder, Simao expected the fort to fall easily as he was told, Simao then ordered his men to land ashore alongside the cannons, there he again bombarded the fort until all the gunpowder was almost used, Simao then held a council to decide whether to assault the fortress by climbing its walls or ask help from Ormus, the council decided not to attack the fort until reinforcements arrive, they then dispatched a ship to Ormus, however, it didn't arrive after 14 days, during which a plague struck the Portuguese which killed 200 men and struck the rest, it is said only 50 remained were capable of fighting, the ship had finally arrived to Bahrain Simao then decided to re-embark. No one was able to carry the cannons to the ships; ropes were tied to the sick and dragged to the ships since they lacked sailors who were experienced at sea. A storm hit the ships, and they all sank except one; Simao drowned.

Kirby Gregory

Kirby Gregory
Graham Patrick "Kirby" Gregory, often credited simply as Kirby (born 11 March 1953 in Wallingford, Berkshire, England) is an English musician best known for playing with rock bands Curved Air and Stretch. He now works in the field of addictions counselling.
Musical career
Gregory began playing guitar aged seven and moved to London in 1969 with bass guitarist Steve Emery. They formed a band called Armada, and recruited vocalist Elmer Gantry before breaking up. In 1972, Gregory joined progressive rock band Curved Air and played on their 1973 album, Air Cut. He also played on one track on the archival release, Lovechild.
After leaving Curved Air, Gregory and Gantry became part of a group of musicians who were assembled by Fleetwood Mac manager Clifford Davis, with the alleged consent of drummer Mick Fleetwood, in order to perform as Fleetwood Mac on a tour of the United States in 1974. Problems between the members of Fleetwood Mac had resulted in them being unable to fulfil their concert obligations. Fleetwood has since denied any role in recruiting the musicians. After it became clear that Fleetwood himself was not going to be involved, audiences quickly realised that this hastily assembled group was not the band they had paid to see, and the tour collapsed after a few weeks. However, Gregory and the other band members stayed together and formed Stretch later that year.
Gregory wrote the hit single "Why Did You Do It?" about the bogus Fleetwood Mac episode, for Stretch and it reached No. 16 in the UK Singles Chart in November 1975. Stretch recorded several albums before splitting up in 1979.
Gregory recorded a solo album Composition on the UK Hot Wax Records label (not the US label of the same name) in 1978, and subsequently played on ex-Fleetwood Mac guitarist Danny Kirwan's final album Hello There Big Boy! in 1979. He also took part in a recording session with Thin Lizzy vocalist Phil Lynott. Gregory and Gantry re-united briefly in 1982 and recorded material with Sweet drummer Mick Tucker and bass player Nigel Ross-Scott but nothing was officially released.
In 2007, Gregory and Gantry reformed Stretch and toured in support of the greatest hits album, Why Did You Do It: The Best of Stretch.
In 2013, Gregory rejoined Curved Air.
Addictions counselling
In 1990, Gregory became involved in addictions counselling and in 1999 he joined Action on Addiction, a UK-based charity that works with people affected by drug and alcohol addiction. He is currently Director of Client Services at the charity and at its subsidiary The Spider Project, and has spoken at major conferences on addiction. He is also a Cognitive Analytic Psychotherapist and an Association of Cognitive Analytic Therapy Accredited Supervisor.

Christiane Chabot

Christiane Chabot (born 17 December 1950) is a French-Canadian artist. She is a multidisciplinary artist, working in the fields of painting, pastels, watercolors, sculpture, installation art, photography and also computer and video graphics.
Life and work
Christiane Chabot was born in December 1950 in Jonquière, Quebec. Chabot studied plastic arts at the Cégep de Jonquière from 1969 until 1971, followed by studying visual art at the Université Laval from 1972 to 1975.
She attended the École des Beaux-Arts twice, first in 1976-77 and again in 1981–82.
She holds a dual citizenship for France and Canada. She works and lives in Paris and Montreal.
The mix of work during the early years, drawing, painting, etching and photography, led towards the opening up of an interdisciplinary perspective that has progressively become firmly established in recent years, with the inclusion of such spheres as sculpture, installations, video and computer graphics.

Graham Matthews

Graham Matthews (born 2 November 1942) is an English former footballer who played in the Football League for Crewe Alexandra, Stoke City and Walsall.
Career
Matthews was born in Newcastle-under-Lyme and joined his local club Stoke City in 1960. He played twice in 1960–61 and made twelve appearances in 1961–62 scoring twice. Unfortunately for Matthews in October 1961 Stoke manager Tony Waddington brought the legendary Stanley Matthews back to the club. Matthews had no hope of retaining his place in the side at the expense of someone like the former England international and he left for Walsall in 1963.
He spent two seasons at Fellows Park where he made 73 appearances scoring 22 goals before joining Crewe Alexandra in 1965. He played 61 times for the "Railwaymen" scoring 19 goals and helped the team finish in 5th position in the Fourth Division in 1966–67.

The Clown (2011 film)

The Clown (2011 film)
The Clown is a 2011 Brazilian comedy-drama film. It is the second feature film directed by Selton Mello, who also stars as the protagonist.
The film follows the story of the father and son Benjamin and Valdemar, who work as clowns Pangaré and Puro Sangue, running the country roads together with the Circus Hope troupe. The clown Benjamin, however, is in crisis. He thinks that he is not funny anymore.
The film was selected as the Brazilian entry for the Best Foreign Language Oscar at the 85th Academy Awards.
Plot
The film tells the story of Benjamin and Valdemar, father and son known as the clowns Pangaré and Puro Sangue. They make their living traveling the country with Circus Hope, without a fixed address, no neighbors, and no ID.
The drama begins when Pangaré, tired of life on the road, feels that he is no longer a funny clown, awakening a lifelong dream of having a place to live and a social security number, proof of residence, and an identity card.

Mello showed the script to actors Wagner Moura and Rodrigo Santoro, offering them the lead role, but the schedule prevented both from accepting the invitation.
Release
The film premiered on October 28, 2011 in 200 theaters throughout Brazil. In the first three days of release the film grossed R$ 2 million, reaching the milestone of 1 million viewers in the third week of screening.

Arthur Erich Haas

Arthur Erich Haas (April 30, 1884 in Brno – February 20, 1941 in Chicago) was an Austrian physicist, noted for a 1910 paper he submitted in support of his habilitation as Privatdocent at the University of Vienna that outlined a treatment of the hydrogen atom involving quantization of electronic orbitals, thus anticipating the Bohr model (1913) by three years.
Haas’ paper, however, was initially rejected and even ridiculed. As noted in his autobiography, Haas recalls: "When I lectured to the Chemical-Physical Society of Vienna ... Lecher ... referred to the presentation during open discussion as a carnival joke" (the lecture was held during carnival time in Austria, February 1910). Soon thereafter, however, by September 1911 at a physical science convention in Karlsruhe, former detractors of Haas' work acknowledged it with greater enthusiasm as noted in a footnote: "We do not know what caused [a] change of mind in 1911 and can merely suggest the general trend of thinking at the time: 1910 saw the beginning of a universal shift of opinion of the quantum concept."
The significance of Haas' work lay in the establishment of a relationship between Planck's constant and atomic dimensions, having been first to correctly estimate the magnitude of what is today known as the Bohr radius.
From 1936 to his death he was professor at the University of Notre Dame.
Acceptance at the 1911 Solvay Conference
During the proceedings of the first Solvay Conference in 1911 at which Bohr’s mentor, Rutherford was present. Max Planck’s lecture ended with this remark: “… atoms or electrons subject to the molecular bond would obey the laws of quantum theory.” Hendrik Lorentz in the discussion of Planck’s lecture raised the question of the composition of the atom based on Thompson’s model with a great portion of the discussion around the Quantum atom developed by Arthur Erich Haas. Lorentz explained that due to the dimension of Planck’s constant, it defined the atom. Haas’s model of the atom is mentioned seventeen times during the Proceedings of the Conference. Planck uses Haas’ model in his speech saying:
“A.E. Haas, for example, takes as oscillator the uniform sphere of J.-J. Thomson, within which an electron can oscillate around the center. The maximum energy for this oscillation, which is reached when the amplitude becomes equal to the radius of the sphere, must be equal to the quantum of energy e = hv.”

Nitarsone

Nitarsone is an organoarsenic compound that is used in poultry production as a feed additive to increase weight gain, improve feed efficiency, and prevent histomoniasis (blackhead disease). It is marketed as Histostat by Zoetis.
Nitarsone once was one of four arsenical food-animal drugs—along with roxarsone, arsanilic acid, and carbarsone—approved by the U.S. Food and Drug Administration for use in feeding poultry. However, following the suspension of sales of roxarsone in the United States in 2011, nitarsone was thought to be the only arsenical animal drug actually marketed in the U.S. In September 2013, the FDA announced that Zoetis and Fleming Laboratories agreed to voluntarily withdraw from using roxarsone, arsanilic acid, and carbarsone, which left nitarsone as the only arsenical approved in the U.S. for use in food animals. But in 2015, the FDA also withdrew approval of nitarsone in animal feeds, effective at the end of 2015.
