Nana (1926 film)

Nana (1926) is Jean Renoir's second full-length silent film and is based on the novel by Émile Zola.

Plot

A government official, Count Muffat, falls under the spell of Nana, a young actress. She becomes his mistress, living in the sumptuous apartment which he provides for her. Instead of elevating herself to Muffat's level, however, Nana drags the poor man down to hers - in the end, both lives have been utterly destroyed.

Production

The film stars Renoir’s wife, Catherine Hessling, in an eccentric performance as the flawed heroine Nana.

Jean Renoir’s film is a fairly faithful adaptation of Émile Zola’s classic novel. The film’s extravagances include two magnificent set pieces – a horse race and an open air ball. The film never made a profit, and the commercial failure of the film robbed Renoir of the opportunity to make such an ambitious film again for several years.

Ulmus 'Nana'

The elm cultivar Ulmus 'Nana' is a very slow growing shrub that with time forms a small tree. It was believed for many years to be a form of Ulmus glabra and is known widely as the 'Dwarf Wych Elm'. However, the ancestry of 'Nana' has been disputed in more recent years, Melville considering the specimen once grown at Kew to have been a cultivar of Ulmus × hollandica.

Description

The tree rarely exceeds 5 m in height, but is often broader. The dark green leaves are smaller than the type, < 11 cm long by 8 cm broad. Green describes it as a very distinct variety not growing above 60 cm in 10 to 12 years. A specimen at Kew was described by Henry as 'a slow-growing hemispherical bush that has not increased appreciably in size for many years'.

Pests and diseases

The low height of the tree should ensure that it avoids colonisation by Scolytus bark beetles and thus remain free of Dutch elm disease.

Cultivation

The tree is still occasionally found in arboreta and gardens in the UK, and has been introduced to North America and continental Europe; it is not known in Australasia.

Mira

Mira (/ˈmaɪrə/, also known as Omicron Ceti, ο Ceti, ο Cet) is a red giant star estimated 200–400 light years away in the constellation Cetus. Mira is a binary star, consisting of the red giant Mira A along with Mira B. Mira A is also an oscillating variable star and was the first non-supernova variable star discovered, with the possible exception of Algol. Mira is the brightest periodic variable in the sky that is not visible to the naked eye for part of its cycle. Its distance is uncertain; pre-Hipparcos estimates centered on 220 light-years; while Hipparcos data from the 2007 reduction suggest a distance of 299 light-years, with a margin of error of 11%.

Observation history

Evidence that the variability of Mira was known in ancient China, Babylon or Greece is at best only circumstantial. What is certain is that the variability of Mira was recorded by the astronomer David Fabricius beginning on August 3, 1596. Observing what he thought was the planet Mercury (later identified as Jupiter), he needed a reference star for comparing positions and picked a previously unremarked third-magnitude star nearby. By August 21, however, it had increased in brightness by one magnitude, then by October had faded from view. Fabricius assumed it was a nova, but then saw it again on February 16, 1609.

Mira (film)

Mira is a 1971 Dutch-Belgian drama film directed by Fons Rademakers. It was entered into the 1971 Cannes Film Festival. The film was selected as the Dutch entry for the Best Foreign Language Film at the 44th Academy Awards, but was not accepted as a nominee.

IBM Mira

Mira is a petascale Blue Gene/Q supercomputer. As of June 2013, it is listed on TOP500 as the fifth-fastest supercomputer in the world. It has a performance of 8.59 petaflops (LINPACK) and consumes 3.9 MW. The supercomputer was constructed by IBM for Argonne National Laboratory's Argonne Leadership Computing Facility with the support of the United States Department of Energy, and partially funded by the National Science Foundation. Mira will be used for scientific research, including studies in the fields of material science, climatology, seismology, and computational chemistry. The supercomputer is being utilized initially for sixteen projects, selected by the Department of Energy.

The Argonne Leadership Computing Facility, which commissioned the supercomputer, was established by the America COMPETES Act, signed by President Bush in 2007, and President Obama in 2011. The United States' emphasis on supercomputing has been seen as a response to China's progress in the field. China's Tianhe-1A, located at the Tianjin National Supercomputer Center, was ranked the most powerful supercomputer in the world from October 2010 to June 2011. Mira is, along with IBM Sequoia and Blue Waters, one of three American petascale supercomputers deployed in 2012.
