The assumption about the formal and semantic link between language and genre is the starting point of this study. The absurd in speech is analyzed in texts written by N. Gogol and D. Kharms, while absurd genres are tackled on the basis of the narratives of Dostoevsky, Camus and Sabato. The reality of modern times and all aspects of its artistic representations have altered the form and ideology...

متن کاملRheumatoid factor interference in the determination of carbohydrate antigen 19-9 (CA 19-9).
BACKGROUND Investigation of a 61-year-old Caucasian male suffering from fatigue and weight loss led to the finding of a carbohydrate antigen 19-9 (CA 19-9) concentration of 80 kU/L using an ADVIA Centaur analyser. Determination of CA 19-9 on Vidas, AxSYM and Architect i2000 systems gave normal results. His rheumatoid factor concentration was very high (900 kIU/L) and assay interference was susp...
متن کاملSynthesis of 1-Hydroxy-2-(Prop-2'-Enyl) 9-Antrone
An efficient synthesis of the 1-hydroxy-2-(prop-2'-enyl)9-anthrone is described. Selective nitration of anthraquinone, reduction to the corresponding amine, diazotization and treatment by sulfuric acid solution afforded the 1-hydroxy-9,10-anthraquinone in good yield as the key intermediate. Reaction with allyl bromide/K2CO3 and subsequent selective reduction accompanie...

In a previous paper we analyzed the perfonnance of networks with negligi ble transmission delay, whose operation is controlled by a simple synchronizer. It was shown that full speed is achieved, for any wake-up pattern, by letting the networlc run free, without the use of a "firing squad" mechanism or a scheduler. In this paper we investigate the effect of fixed delays in the communication cha...
