New Paperback NA This is the definitive guide to valve selection. It covers the fundamentals of valve construction and application, and analyzes the different hazards and requirements of all types of industrial fluid flow situations. This third edition expands the coverage of pressure relief valves and rupture discs. It includes a new section on damping valve chatter, which is a serious problem in installations such as atomic power plants where valve chatter could have catastrophic consequences to the safety of a plant. There is also new information on performance of spring-loaded pressure relief valves and a closer examination of valve selection with respect to rupture discs and explosion venting.

Nedopil, Alexander: Die closed wedge Basisosteotomie zur Therapie des Hallux valgus Retrospektive Analyse von 86 Füßen nach operativer Vorfußchirurgie unter Anwendung einer mini L-Platte, SÜDWESTDEUTSCHER VERLAG FÜR HOCHSCHULSCHRIFTEN, November 2009, Besorgungstitel - vorauss. Lieferzeit 3-5 Tage. ISBN: 3838111753
Ziel der Studie war es, das Langzeitergebnis der proximalen closed wedge Ostoetomie zur Korrektur des Hallux valgus zu analysieren. Die Osteosynthese erfolgte durch eine mini L-Platte. Die proximale closed wedge Osteotomie wurde im Durchschnitt 52 Monate postoperativ retrospektiv analysiert. 66 Patientinnen (86 Füße) nahmen an der Studie teil. Der AOFAS-Score wurde angewendet um das postoperative Ergebnis zu bewerten. Anhand prä- und postoperativer Röntgenbilder wurde die ossäre Entwicklung ausgewertet. 95.5% der Patientinnen waren mit dem Ergebnis der Operation zufrieden, 3 Patienten (4.5%) waren nicht zufrieden. Der HV-Winkel verbesserte sich im Durchschnitt um 22.1° (präoperativ 36.4° zu postoperativ 14.3°) und der IM-Winkel wurde von durchschnittlich 17.6° auf durchschnittlich 6.5° reduziert. Die durchschnittliche Verkürzung des ersten Metatarsale betrug 3.2 mm. Der durchschnittliche AOFAS-score war 78 Punkte. Fazit Die Resultate bestätigen, dass die closed wedge Basisosteotomie bei mäßig bis schweren Hallux valgus indiziert ist. Die Gefahr der Transfermetatarsalgie kann durch suffiziente Osteosynthese reduziert werden.

Wallace, Edgar,
Edgar Wallace (1875-1932), Schriftsteller. E. Manuskript mit U. O. O. u. D. [Berlin, 11. Dezember 1928]. 2 SS. auf 3 Bll. 4°. - Sehr eindringliche Reflexion über das eigene Schaffen, über Bühne und Film und Kunst im Allgemeinen und auch über Berlin, wo der Schriftsteller sich gerade aufhielt, um einer Aufführung seines Stücks "Der Zinker" beizuwohnen, das zur selben Zeit, eben am 11. Dezember, unter dem Titel "The sign of the Leopard" am Broadway seine Premiere feierte: "It is two o'clock in the morning and very cold. Does Berlin ever go to sleep? It is the most restless and yet the most restful city in the world. It has the hum of London but there are times when London is quiet and the streets are deserted but in Berlin the night revellers going home meet the early risers going to work ... there will be snow I think - I can smell it in the air. I suppose I should be wise and go to bed. But to leave a play that is three parts written is very difficult for me. Still I can get up early in the morning. I wonder how Der Zinker' will be received? The company is an excellent one, but it is curious to listen to your own play in a language which you cannot understand. And yet it is fascinating to listen to these rich German voices and watch the actors move and gesticulate ... It is eight o'clock in New York, the curtain is up on the premiere of Der Zinker' (they call it The Sign of the Leopard' there)[.] Will Carl Brandt telephone me from New York ... I wonder what sort of a girl is playing the principal role? Some German girls have a certain appealing beauty [...] What was the name of that girl I met yesterday? [...] I should like to be able to read what t[he] German correspondent wrote about my views on art. So many English people use the word art' when they mean aesthetic'. They tell me I am not an artist because I write about criminals. Other people are artists when they write about God and show him in plus fours [d. s. kurze Hosen, die zehn Zentimeter unters Knie reichen und im Allgemeinen zum Sport getragen werden]. I have my own views on the personal God but there are millions of people to whom he is something real and beautiful. Why wound the spirit of millions of good people? It is like desecrating the grave of a mans mother. But it may be good art. I don't know. I am bourgeoisie I suppose ... Half past two ... taxis and cars still rolling to and from the Brandenburger Tor. A restless friendly city. How hard everybody works and how serious they are ... They work hard on the stage and in the studios ... there were two or three English actors in the cinema-studio I visited this afternoon. They were sorry that the film was finishing ... Everybody had been so kind to them[.] My God they work hard!' said one but they work to schedule! You know exactly what you have to do and when you have to do it!' ... Bed is a nice place but that wedge shaped bolster under your head is an abomination ... What was the name of that young German actress? ... Very lovely ... I wonder how she would film? ... God in plus fours ... art has many expressions [...]". - Tls. mit winzigen Randläsuren, sonst sehr wohlerhalten, wenn auch etwas fleckig.

Mani Bhaumik: Code Name God, Penguin Books ,2006 ,New Delhi ISBN: 0144001039

The split between man and maker has long been widening, and many acknowledge that the wedge is science. Is God dead? Are religion and faith merely opiates of the masses? Is science responsible for driving a wedge between man and his maker? Till about four hundred years ago, belief in divine power dominated world thought. With developments in science and increasing philosophical scepticism, man appeared to lose faith in God. But science itself has proved to be a false god, leaving in its wake a disillusioned and despondent mankind.; Paperback
