The Unpublished Drafts of Five Poems on Julian the Apostate by C. P. Cavafy
1981
The texts which are being published here for the first time are part of a group of drafts conserved in the Cavafy Archive, which George Savidis first brought to light; they are poems ‘which Cavafy did not have time to finish, and which he was considering with distress during the last months of his life. Carefully preserved by the poet himself in makeshift dossiers, each with its provisional title and the date, they cover the period from 1918 to 1932 and, together with the nearly completed drafts of a few already published poems… and of some unpublished but completed poems, offer us a unique, unexpected, extremely moving image of the stages of Cavafy’s creation’. Among these unfinished poems…

Vacancies and Carbon Impurities in Iron
1981
Point defects in electron-irradiated high-purity α-iron have been studied by positron lifetime measurements. We show that the migration stage of monovacancies occurs already as low as at 220 K, which results in agglomeration of small three-dimensional vacancy clusters. Furthermore, we irradiated carbon-doped iron specimens, where formation of highly asymmetric monovacancycarbon atom pairs was detected during the migration stage of monovacancies at 220 K.
Финансово-кредитные рычаги в системе управления народным хозяйством

La carte scolaire : un instrument efficace mais inégalitaire
1981
International audience; Ce texte constate que : - la carte scolaire est un instrument globalement efficace pour la collectivité ; - la carte scolaire place les individus dans des situations très inégales. Nous tentons ensuite de montrer que la raison de ce décalage réside dans le fait que l'administration de l'éducation n'a pas coordonné la carte scolaire avec sa politique sociale

Computed Tomography in Brain Tumors
1981
Craniocerebral injury and brain tumor are the two most important indications for CT studies. There is unanimous agreement that computed tomography is unequalled in its diagnostic accuracy in demonstration of intracranial tumors. Our own experience is based on observations in 3,750 patients with brain tumors or cerebral metastases who were studied in the period from December 1974 to March 1980 (Table 1). Initial CT studies demonstrated the intracranial tumor or tumors in 3,589 cases (95.7%). Several CT examinations were necessary for diagnosis of a brain tumor in 112 patients (3.0%). Other diagnostic procedures or postmortem studies revealed a brain tumor which had not been demonstrated with…

Prediction of the next value of a function
1981
The following model of inductive inference is considered. Arbitrary set tau = {tau_1, tau_2, ..., tau_n} of n total functions N->N is fixed. A "black box" outputs the values f(0), f(1), ..., f(m), ... of some function f from the set tau. Processing these values by some algorithm (a strategy) we try to predict f(m+1) from f(0), f(1), ..., f(m). Upper and lower bounds for average error numbers are obtained for prediction by using deterministic and probabilistic strategies.

Hacia una fundamentación teórica de la política cultural
1981
La cultura política, definida como la capacidad de los grupos o individuos para interferir decisivamente en la vida cultural de la comunidad, está ausente en la concepción moderna del estado como lugar de política y políticas. Los paradigmas normalizados de la alta cultura, la cultura democrática (el arte como preferencia de masas)y la democracia cultural (participación de las masas en el arte) son reemplazados por una concepción epistemológica del arte fundada en categorias de identidad, patrimonio, participación en la comunidad, la creatividad como experiencia y la creación. Se sugiere que el papel práctico de la cultura dentro de la comunidad está condicionado por nuestra concepción teór…
The role of bestatin, an inhibitor of cell surface proteases, in the interaction of serum with untransformed cells in culture.
1981
Bestatin is an inhibitor of cell surface-associated aminopeptidase B and leucine aminopeptidase. This microbial product simulates the role of serum as an activator of uridine uptake in quiescent BHK cells. The compound significantly stimulates the incorporation of labelled thymidine into the acid-insoluble fraction of serum-starved Nil 8 cells in the presence of low concentration of serum. The possible mechanisms of these interactions are discussed.
The crystal and molecular structures of hexaquocobalt(II) diisonicotinate N-oxide and its isostructural nickel(II) homologue
1981
Abstract In this experiment the crystal and molecular structures of hexaaquocobalt(II)diisonicotinate N-oxide were determined from three-dimensional X-ray diffraction dat. The crystals belong to the monoclinic space group P2 1 /c. The cell parameters are a = 7.74(2), b = 9.826(2), c = 11.474(2) A , β = 91.08(2)°, V = 873.2(3) A 3 for the Co-complex, and a = 7.765(2), b = 9.725(6), c = 11.363 A , β = 91.20(3)°, V = 857.9(7) A 3 for the Ni-complex. Both structures were refined to a final R-value of 0.045. The X-ray structure analysis showed that there are metal(II)hexaquo cations and isonicotinate N-oxide anions formulated as Co(H 2 O) 6 2+ 2L − and Ni(H 2− O) 6 2+ 2L − in the structures. The…
Alternativen zur Bonferroni -Prozedur
1981
Erst vor kurzem veroffentlichte HOLM (1979) eine schrittweise Prozedur, die im allgemeinen Fall multipler Tests (keine Annahmen uber die Abhan gigkeit der Tests untereinander) die experimentweise Fehlerrate αEW unter Kontrolle halt und scharfer ist als die ubliche Bonferroni-Methode. Die „Schwachstelle“ der HOLM'sehen Prozedur liegt am Anfang, wo - genauso wie bei Bonferroni - die Irrtumswahrscheinlichkeit durch die Zahl der Tests geteilt werden mus. Im folgenden sollen Testprozeduren angegeben werden, die unter denselben Bedingungen mit weniger restriktiven Irrtumswahrscheinlichkeiten auskommen.
