Rocket from the Tombs (RFTT) était un groupe rock américain actif de la mi-1974 à la mi-1975 à Cleveland (Ohio), figure de la scène qu’on appellera plus tard Cleveland-punk.
Reconnus aujourd’hui comme un important groupe protopunk, ils furent cependant peu connus durant leur brève existence, mais c’est un groupe séminal car plusieurs de leurs membres poursuivirent leurs carrières au sein de groupes plus reconnus comme Pere Ubu et The Dead Boys. Billy Bob Hargus écrit cependant que The sound of the Rockets is much more ferocious than Ubu or the Dead Boys. (« le son des Rockets est bien plus féroce »)

En 1974, la formation originelle comprend Chris Cuda, Peter Laughner, and Glen « Thunderhand » Hach aux guitares, Charlie Weiner à la basse, Tom Foolery (né Clements) à la batterie. Après quelques changements de personnel, la formation la plus connue est composée de David Thomas (alors appelé « Crocus Behemoth », chant et saxophone), Peter Laughner (guitare et chant), Craig Bell (basse, chant), Gene O’Connor (alias Cheetah Chrome, guitare et chant), et Johnny Madansky (aujourd’hui “Johnny Blitz”, batterie).
À la séparation de RFTT, les membres formèrent deux groupes différents :
Les deux groupes utilisèrent des chansons du répertoire de Rocket From The Tombs : The Dead Boys enregistrèrent Ain’t It Fun, What Love Is, Down in Flames, Caught With the Meat in Your Mouth (I’m Never Gonna Kill Myself Again chez RFTT) et Sonic Reducer; Pere Ubu réinterprétèrent Final Solution, Life Stinks et 30 Seconds Over Tokyo.
Rocket From The Tombs n’enregistrèrent jamais d’album, mais divers enregistrements en concerts et démos circulèrent sous la forme de disques pirates. La plupart furent utilisés pour un cédé officiel chez Smog Veil records appelé The Day the Earth Met the Rocket from the Tombs (2002).
Le cédé chez Smog Veil a renouvelé l’intérêt pour le groupe qui s’est reformé en 2003, avec Thomas, Chrome, et Bell, rejoints par le guitariste Richard Lloyd (guitare ; des années auparavant quand Lloyd quitta brièvement Television, Laughner avait été envisagé pour le remplacer) et Steve Mehlman (batterie).
Le 10 juin 2003, ils jouèrent un concert à la radio dans l’émission de Brian Turner sur WFMU. En 2004, Smog Veil et Morphius sortirent Rocket Redux, des originaux de Rocket From The Tombs joués en studio par le groupe de 2003.
En 2006, Thomas a annoncé que le groupe se reformait pour enregistrer des titres nouveaux et le groupe a fait une tournée d’été.

Peter Roggisch

Peter Roggisch (* 10. August 1937 in Berlin; † 21. Februar 2001 in Hamburg) war ein deutscher Schauspieler und Regisseur, der sowohl für das Theater als auch für den Film sowie als Sprecher für Audioproduktionen unter so bekannten Regisseuren wie Alexander Kluge, Hans Neuenfels, Peter Palitzsch und Peter Zadek arbeitete. Er gehört zu den bedeutendsten Shakespeare-Darstellern Deutschlands.

Peter Roggisch studierte nach dem Besuch eines Gymnasiums in Hamburg zunächst vier Semester Jura und nebenbei Schauspielkunst an der Schauspielschule Frese. Er trat an Amateurbühnen in Hamburg auf und erhielt 1958 mit 21 Jahren sein erstes Engagement am Berner Ateliertheater, wo er in Blick zurück im Zorn von John Osborne debütierte. 1960 wurde er zunächst wegen des Ausfalls eines Schauspielers an das Wiener Burgtheater gerufen, danach verlängerte sich sein Engagement wegen des Ausfalls eines anderen Schauspielers um eine weitere Produktion. Anschließend ging er an die Hamburger Kammerspiele.
Von 1962 bis 1964 war er an der Basler Komödie tätig, danach spielte er acht Jahre am Staatstheater Stuttgart (1964 bis 1972) und im Anschluss acht Jahre am Schauspiel Frankfurt. Dort engagierte er sich mit Palitzsch, Neuenfels und anderen am dort praktizierten Mitbestimmungstheater-Projekt. Weitere acht Jahre war er am Schauspielhaus Bochum tätig. Auch etwa am Schauspielhaus Zürich, an der Freien Volksbühne Berlin und an der Berliner Schaubühne war er zu sehen. Neben seinen Engagements am Theater trat er immer wieder in Filmen auf und wirkte als Sprecher in Hörspielen und für Hörbücher mit.
Die letzten Jahre spielte er in seiner Wahlheimat Hamburg regelmäßig bei Martin Kušej am Thalia-Theater, dessen Ensemble er seit 1998 angehörte. Zuletzt trat er als Direktor Hummel in der Gespenstersonate nach August Strindberg und, nach einer Hirntumorerkrankung im Rollstuhl sitzend, mit einer Reihe von Lesungen aus Dantes Göttliche Komödie auf, bis das Fortschreiten seiner Krankheit keine weiteren Bühnenauftritte mehr zuließ.
Peter Roggisch zählt auch nach seinem Tod zu den bedeutendsten Shakespeare-Darstellern Deutschlands. Auch in Stücken von Brecht wusste er durch seine differenzierte Spielweise zu glänzen. Zeitlebens hatte er Engagements an vielen der bedeutendsten deutschsprachigen Bühnen.
Die Zeit bezeichnete ihn in einer Besprechung der Hamlet-Aufführung von Palitzsch in Stuttgart als „sicher einer der talentiertesten, feinnervigsten Schauspieler des deutschen Theaters“ und in einer Besprechung des Prinzen Sigismund als „sensible[n] und technisch vielseitige[n] Schauspieler“. Selbst das in seiner politischen Tendenz dem bürgerlichen Theater äußerst kritisch gegenüberstehende Theaterlexikon des Henschelverlags bescheinigte ihm, dass „Roggisch seine Figuren analysiert und kommentiert, sie aus widersprüchlichen Situationen zusammensetzt, […] um bürgerliche Verhaltensweisen aufzudecken und zu kritisieren, aus der Absicht, bürgerliche Verhältnisse zu überwinden oder zu verändern […]“.
Die Zeitschrift Theater heute schrieb in Heft 9 des Jahrgangs 1977: „Und dann gab es in Stuttgart eine Aufführung, in der Palitzsch seinen diffizilen Realitätssinn im Zusammenwirken mit zwei Schauspielern meisterhaft an einem Stück wirksam werden ließ, das bis dahin als verrätseltes Parabel verstanden worden war: Becketts ‚Warten auf Godot‘. Die beiden Wartenden waren eben wartende Landstreicher, gespielt von Gerhard Just und Peter Roggisch. Ihr Warten trat nicht auf der Stelle, sondern war ausgefüllt von menschlicher Realität von dem Prozess der vielfältigen Beziehungen zwischen den beiden Wartenden. So deutlich und genau jede Phase dieses Prozesses vorgeführt wurde, so sehr blieb jede Einzelheit zart, verletzlich, liebevoll. Ein heiter-nüchterner Abend, an dem sich Justs Massigkeit und Steifigkeit so weit verfeinerte wie sich die Empfindungsschnelligkeit und –flüssigkeit von Peter Roggisch festigte, überprüfbar wurde. Die beiden zeigten, was das ist: Zusammenspiel.“

Germania Magna

La Germania Magna era, secondo l’etnologia geografica dell’Antica Roma, una vasta area dell’Europa centrale non soggetta al domino romano (se non parzialmente e per brevi periodi), che si estendeva a oriente del Reno e nella quale era stanziata la maggior parte delle tribù germaniche. Al tempo di Augusto, i Romani ne intrapresero la conquista a partire dal 12 a.C. Nell’anno 6 d.C., tutta la Germania fino al fiume Elba era occupata e pacificata. Il consolidamento della conquista della Germania Magna non ebbe luogo a seguito della disfatta romana nella battaglia della foresta di Teutoburgo, avvenuta nel 9 d.C. Augusto intuì, così, già allora che i confini dell’Impero Romano dovessero essere stabiliti al Reno e al Danubio. Secondo questa politica di “smobilitazione” della frontiera di là del Reno, opereranno tutti gli imperatori successivi, da Tiberio (che mostrò indifferenza alla rivolta dei Frisi), a Claudio e a Nerone, che fermarono le iniziative di Corbulone in quei territori), fino a Domiziano quando fu creata una zona militarizzata (limes) tra Roma e la Germania.

Se i confini settentrionali (geografici) e quelli occidentali e meridionali (politico-geografici) della Germania Magna erano definiti, quelli orientali rimasero sempre sfumati. A ovest la regione era limitata dal corso del fiume Reno; a sud, da quello del Danubio. Lungo i due fiumi correva il Limes, la lunga frontiera settentrionale dell’Impero romano che si estendeva dal Mare del Nord al Mar Nero. A nord, la Germania Magna era limitata da due mari, il Mar Baltico e lo stesso Mare del Nord. A est, invece, il suo territorio proseguiva indefinitamente, fino a dove erano presenti insediamenti di tribù germaniche.
I Romani ebbero sempre una conoscenza approssimativa dell’esatta composizione etnica e della stessa conformazione fisica delle aree orientali delle terre dei Germani e la loro definizione geografica (Germania Magna, appunto), coincideva con quella etnica. Integrando lo schema romano con le moderne conoscenze storiche, i confini orientali della Germania Magna si possono pertanto precisare come grosso modo coincidenti con il corso del fiume Vistola, al di là del quale si estendevano le terre abitate in prevalenza da Balti e Slavi. Non esistette mai, comunque, una linea di confine netta tra i Germani e gli altri popoli; le varie tribù si intervallavano, si spostavano le une nelle terre delle altre, si scontravano e si fondevano continuamente, determinando il carattere costantemente fluido della regione, almeno dal punto di vista della composizione etnica.
Allo stesso modo, anche il limite sudorientale della Germania Magna era indefinito; più che un confine, esisteva un’area di transizione verso le regioni abitate dai Sarmati e, più a sud, dai Pannoni: la Pannonia, a popolazione mista celtico-illirica (Pannoni).
L’area che sarebbe stata identificata dai Romani con il nome di Germania Magna fu abitata in parte, fino al IV secolo a.C., da popolazioni celtiche, stanziate soprattutto nelle aree occidentali e meridionali. Già a partire dal V secolo, tuttavia, ebbe inizio un continuo processo espansivo dei Germani verso sud, a partire dalla loro patria originaria tra Scandinavia e coste del Mar Baltico. Verso il II-I secolo a.C., quando ebbero inizio i contatti con quei Romani che avrebbero definito “Germania Magna” la regione, la sua popolazione era ormai in gran parte germanica. In particolare, i Germani della Germania Magna appartenevano ai due sottinsiemi linguistici dei Germani occidentali (a loro volta ripartiti in Ingaevones, Istaevones e Herminones) e dei Germani orientali.
La predominanza germanica nella regione è rimasta sostanzialmente costante fino ai nostri giorni, anche se nelle aree orientali già nell’antichità il contatto con Balti e Slavi si tradusse in alternanze, mescolanze e scontri tra i vari gruppi etnici.
Essendo Germania Magna un’espressione politico-geografica prettamente romana, la sua storia coincide con quella dei suoi rapporti con Roma e con quella dei suoi popoli nei secoli di contatto con la civiltà romana. Tale storia è caratterizzata in una prima fase dai continui scontri lungo il Limes tra le tribù germaniche e l’Impero romano (I-III secolo d.C.); in una seconda fase (III-VI secolo) a essere predominanti sono le ondate migratorie che dalla Germania Magna mossero verso l’Impero, determinando continui rimescolamenti di popolazioni.

Canton de Châteauroux-Est

Le canton de Châteauroux-Est est une ancienne division administrative française, située dans le département de l’Indre, en région Centre-Val de Loire.
À la suite du redécoupage cantonal de 2014, le canton a été supprimé en mars 2015, les communes de Châteauroux (fraction cantonale) et de Déols dépendent désormais du canton de Châteauroux-1, alors que Montierchaume dépend du canton d’Ardentes.

Ce canton était organisé autour de la commune de Châteauroux, dans l’arrondissement éponyme. Il se situait dans le centre du département.
Son altitude variait de 140 m (Déols) à 169 m (Montierchaume).
Le 15 février 1790 a été créé le « canton de Châteauroux ». En 1801,, une modification est intervenue. Ce n’est qu’en 1973 que les cantons de « Châteauroux-Centre », « Châteauroux-Est », « Châteauroux-Ouest » et « Châteauroux-Sud » ont été créés.
Il a été supprimé en mars 2015, à la suite du redécoupage cantonal de 2014.
Le canton de Châteauroux-Est était composé de deux communes entières et d’une fraction cantonale de la commune de Châteauroux .

La pyramide des âges, à savoir la répartition par sexe et âge de la population, du canton de Châteauroux-Est en 2009 ainsi que, comparativement, celle du département de l’Indre la même année sont représentées avec les graphiques ci-dessous. La population du canton comporte 51,8 % d’hommes et 48,2 % de femmes. Elle présente en 2009 une structure par grands groupes d’âge légèrement plus âgée que celle de la France métropolitaine[Note 1]. Il existe en effet 92 jeunes de moins de 20 ans pour cent personnes de plus de 60 ans, soit un indice de jeunesse[Note 2] de 0,92, alors que pour la France cet indice est de 1,06. L’indice de jeunesse du canton est par contre supérieur à celui du département (0,67) et inférieur à celui de la région (0,95).

Sally Preston

Sally Preston (born 1964) is a successful UK entrepreneur and founder of the frozen babyfood company Babylicious. She is an advisor of the Conservative Party (UK) as a member of the New Enterprise Council.

Preston gained a degree in Food science and then joined Marks & Spencer’s ready-meals department in the 1980s. She left in 1999 to do consultancy work, partly motivated by the need to find a better balance between her working life and motherhood.
Preston founded Babylicious in 2001, partly because she had seen a need for high quality frozen baby food, and partly because, being newly divorced and diagnosed with skin cancer, she felt that “life’s pretty bad as it is already, what have I got to lose?”[citation needed]
The early years of Babylicious were notable for a series of problems, including theft of the company’s name and consequent litigation, and a vendetta campaign staged by an ill-wisher who impersonated an official to make derogatory calls to Preston’s customers. However her company today has a turnover of £2.5M p.a. and the value of the brand is estimated at £4M.

Lili Larys

Lili Larys (Helena Maliszewska-Płaczkiewicz, primo voto Osmólska) (b. March 19, 1909 in Yalta, Crimea – d. August 24, 1986 in Katowice, Poland) – Polish dancer.
She was born to a Polish family in Yalta in the Crimea. Her parents were Andrzej Maliszewski and Teodozja Rytter. In 1905 they left Warsaw for the Crimea because of the illness of Andrzej. He was a chemist in Yalta and he run successful Russian-French business there. She practiced ballet while in Russia. Their house in the Crimea was visited by, among others, Ivan Mosjoukine, who taught her how to dance tango. Helena and her mother returned to Warsaw in November of 1922. She continued her studies in Poland including the ballet school. Her father Andrzej had to escape from the Crimea to France because of the Bolsheviks in 1918.
Helena made her debut in 1926 and began performing solo and as a partner of, among others, the ballet master Konrad Ostrowski and Andrzej Śnieżyński in theaters, cabarets and nightclubs of Warsaw and other Polish cities. She performed in Momus ( Warsaw movie theater). A Warsaw critic, Ludwik Szmaragd, wrote September 1, 1928 saw the opening of a great revue [..] In the new ensemble there is [..] an excellent dance duet of Larys-Ostrowski . She played in revue Moryc, give me a son in Momus and one of the critics (Roman Jax) wrote: From the entire program, only a ballet number Carnival in Venice, performed by a duo Larys-Ostrowski [..] won sincere appreciation of the audience . Another review stated The highlight of the entire program was the scene In an opium den performed by virtuoso dancers Ostrowski and Larys. At that time her impresario was Blachman, who for a short time, was also the announcer of Momus. It was he who suggested the stage name Larys. Her performances Taniec Ognia to the music of Rimsky-Korsakov, The Dying Swan to the music of Saint-Saëns and Tango apaszowskie (Apache Tango) to the music of Tango Illusion by Erwin Hentschel were particularly well received. She danced to the music performed by the well known Polish orchestra leaders such as Zygmunt Karasiński, Szymon Kataszek and Arnold Lewak.
In addition to Momus she danced in other Warsaw cabarets: Czarny Kot (Black Cat), Czerwony As (Red Ace), Nitouche. She performed in many Polish cities, including Lviv, Poznan, Lodz, Krakow, Katowice, Sopot, and in 1929, in Katowice cabaret Mascotte. In the years 1927-1933 she collaborated with Nelly Ignatowska, Ina Ney, Andrzej Śnieżyński, Irena Topolnicka, Iga Korczyńska, Konrad Ostrowski, Zdzisław Żadejko. She performed on stage until the end of 1933. In that time her longtime sweetheart was Mieczysław Stefanicki, a Polish airforce officer. In 1934 she completed a training course organized by the Institut de Beauté Clytie in Paris and later in the same year she launched her own beauty parlor called Madeleine in Poznań at the December 27 Street. In August 30, 1939 she decided to escape from Poznań to the East of Poland. Years of the II World War and that of German occupation of Poland (1939-1945) she spent in the cities of Biała Podlaska and Lublin. In 1945, just after the war, along with her second husband she settled in Katowice. She had a daughter and two sons, the youngest is Jerzy Płaczkiewicz. She is buried in the cemetery in Katowice.

Symplectic matrix

In mathematics, a symplectic matrix is a 2n×2n matrix M with real entries that satisfies the condition

 
 
 
 
(1)
where MT denotes the transpose of M and Ω is a fixed 2n×2n nonsingular, skew-symmetric matrix. This definition can be extended to 2n×2n matrices with entries in other fields, e.g. the complex numbers.
Typically Ω is chosen to be the block matrix
where In is the n×n identity matrix. The matrix Ω has determinant +1 and has an inverse given by Ω−1 = ΩT = −Ω.
Every symplectic matrix has unit determinant, and the 2n×2n symplectic matrices with real entries form a subgroup of the special linear group SL(2n, R) under matrix multiplication, specifically a connected noncompact real Lie group of real dimension n(2n + 1), the symplectic group Sp(2n, R). The symplectic group can be defined as the set of linear transformations that preserve the symplectic form of a real symplectic vector space.
An example of a group of symplectic matrices is the group of three symplectic 2×2-matrices consisting in the identity matrix, the upper triagonal matrix and the lower triangular matrix, each with entries 0 and 1.

Every symplectic matrix is invertible with the inverse matrix given by
Furthermore, the product of two symplectic matrices is, again, a symplectic matrix. This gives the set of all symplectic matrices the structure of a group. There exists a natural manifold structure on this group which makes it into a (real or complex) Lie group called the symplectic group.
It follows easily from the definition that the determinant of any symplectic matrix is ±1. Actually, it turns out that the determinant is always +1. One way to see this is through the use of the Pfaffian and the identity
Since and we have that det(M) = 1.
Suppose Ω is given in the standard form and let M be a 2n×2n block matrix given by
where A, B, C, D are n×n matrices. The condition for M to be symplectic is equivalent to the conditions
When n = 1 these conditions reduce to the single condition det(M) = 1. Thus a 2×2 matrix is symplectic iff it has unit determinant.
With Ω in standard form, the inverse of M is given by
The group has dimension n(2n + 1). This can be seen by noting that the group condition implies that
this gives equations of the form
where is the i,j-th element of M. The sum is antisymmetric with respect to indices i,j, and since the left hand side is zero when i differs from j, this leaves n(2n-1) independent equations.
In the abstract formulation of linear algebra, matrices are replaced with linear transformations of finite-dimensional vector spaces. The abstract analog of a symplectic matrix is a symplectic transformation of a symplectic vector space. Briefly, a symplectic vector space is a 2n-dimensional vector space V equipped with a nondegenerate, skew-symmetric bilinear form ω called the symplectic form.
A symplectic transformation is then a linear transformation L : V → V which preserves ω, i.e.
Fixing a basis for V, ω can be written as a matrix Ω and L as a matrix M. The condition that L be a symplectic transformation is precisely the condition that M be a symplectic matrix:
Under a change of basis, represented by a matrix A, we have
One can always bring Ω to either the standard form given in the introduction or the block diagonal form described below by a suitable choice of A.
Symplectic matrices are defined relative to a fixed nonsingular, skew-symmetric matrix Ω. As explained in the previous section, Ω can be thought of as the coordinate representation of a nondegenerate skew-symmetric bilinear form. It is a basic result in linear algebra that any two such matrices differ from each other by a change of basis.
The most common alternative to the standard Ω given above is the block diagonal form
This choice differs from the previous one by a permutation of basis vectors.
Sometimes the notation J is used instead of Ω for the skew-symmetric matrix. This is a particularly unfortunate choice as it leads to confusion with the notion of a complex structure, which often has the same coordinate expression as Ω but represents a very different structure. A complex structure J is the coordinate representation of a linear transformation that squares to −1, whereas Ω is the coordinate representation of a nondegenerate skew-symmetric bilinear form. One could easily choose bases in which J is not skew-symmetric or Ω does not square to −1.
Given a hermitian structure on a vector space, J and Ω are related via
where is the metric. That J and Ω usually have the same coordinate expression (up to an overall sign) is simply a consequence of the fact that the metric g is usually the identity matrix.
If instead M is a 2n×2n matrix with complex entries, the definition is not standard throughout the literature. Many authors adjust the definition above to

 
 
 
 
(2)
where M* denotes the conjugate transpose of M. In this case, the determinant may not be 1, but will have absolute value 1. In the 2×2 case (n=1), M will be the product of a real symplectic matrix and a complex number of absolute value 1.
Other authors retain the definition (1) for complex matrices and call matrices satisfying (2) conjugate symplectic.
