No existe realmente vocabulario específico de la teoría del cine, sentenciaba rotundamente Jacques Aumont en 1969. Y son los años en que Aumont sentencia la falla del cine respecto a la filosofía, la linguistica, etc , fructíferos en debates y polémicas cuyos protagonistas toman al asalto las páginas de Cahiers du cinéma y Cinéthique. El hecho de que el despistado Jean Patrick Lebel tercie en la polémica blandiendo las posiciones del PCF , decide a J . L. Comolli a una revisión de conjunto en unos artículos casi míticos hoy (4) . En el cuarto de éstos, Comolli descri be la operación empírico-ideológica de innumerables tratados clásicos y modernos: la naturalización del metalenguaje técnico …
The Role of the Classical Pathway for the Bactericidal Effect of Normal Sera Against Gram-Negative Bacteria
1985
Many gram-negative bacteria are killed after treatment with normal serum. This phenomenon was already described in 1889 by Buchner. The serum-bactericidal effect is abolished when serum has been incubated for 30 min at 56° C. Gram-positive bacteria are less sensitive than gram-negative bacteria to direct killing, although gram-positive cocci are opsonized by the action of serum mediated by antibodies and complement (Inoue et al. 1968; Johnston et al. 1969). Normal sera exhibit bactericidal and bacteriolytic properties against some gramnegative strains; whereas, other gram-negative strains are serum resistant. It has been shown that serum from C4-deficient guinea pigs is able to kill some gr…
Cycle-triggered averaging of respiration-related neuronal activity
1985
Abstract A computer system is presented which provides off-line computation of cycle-triggered histograms (CTH) of respiration-related neuronal activity. Binwidths of the histograms are freely selectable by software from 10 ms to 100 ms. For special evaluation purposes. CTHs can be standardized in different ways concerning cycle duration as well as amplitude. Time incidence of maximum frequency, center of gravity and expiration-to-inspiration phase transition within the respiratory cycle are computed. The system employs special hardware interfaces to an 8-bit microcomputer which are briefly described. Data acquisition, data manipulation and output handling of the results are performed by ch…
Human chromophobe cell renal carcinoma
1985
Twelve renal cell carcinomas composed of "chromophobe" cells are described. This is the first report of renal chromophobe cell tumors in humans neoplasms of this cell type having been described previously only in experimentally induced adenomas in animals. By light microscopy chromophobe cells have slightly opaque or finely reticular cytoplasm when stained with haematoxylin and eosin. They may be distinguished from the clear cells of hypernephroid renal cell carcinomas by the strongly positive reaction of their cytoplasm with Hale's (1946) colloidal iron method and the weaker positive reaction with alcian blue. Vesicular structures, often containing internal vesicles, and possibly derived f…

Computerized Interpretation of H P L C Chromatogramms by Means of Absorbance Ratio Method and Derivative Spectroscopy
1985
As in other chromatographic processes it is the aim of high pressure liquid chromatography (HPLC) to identify the components of a mixture, whereby there may be some information on the class of substances in question. The analytical procedure can shortly be desribed as follows. The mixture is injected in a mobile phase (solvent) and passes a column where the separation takes place. The separated components leave the column at different retention times. A following detection device generates a signal as a function of concentration (chromatographic peak). Usually the components are identified by relating retention times of external standards to the times of occurence of chromatographic peaks. …
A case of lipogranulomatosis Farber: some clinical and ultrastructural aspects
1985
A 20-month-old girl showed typical clinical signs of Farber disease: hoarseness since birth, and periarticular subcutaneous painful nodules. Complete deficiency of acid ceramidase activity was found in cultured skin fibroblasts. An electron microscopic examination of a dermal nodule disclosed pathognomonic tubular inclusions in histiocytes. In epidermal cells zebra-body-like and needle-like lysosomal inclusions were found. Their ultrastructure is different from that of the intrahistiocytic lysosomal inclusions. Probably three clinical types of Farber disease may be distinguished according to the symptomatology and the course of the disease: a severe type, an intermediate type and a relative…

Gas—liquid chromatographic analyses
1985
Abstract The gas chromatographic retention behaviour of methylethyl, 1-methylpropyl, 2-methylpropyl, 1,2-dimethylpropyl, 1-methylbutyl and 3-methylbutyl esters of benzoic and o-, m- and p-chlorobenzoic acids on low-polarity (SE-30) and polar (OV-351) capillary columns under several temperature-programmed and isothermal conditions is reported. The retention data and the Kovats retention indices for all 24 components are given and the separation of a complex mixture is discussed. The retention index increments have been used to examine the effects of chain branching and chlorine substitution. The results are compared with those for n-alkyl benzoates and monochlorobenzoates.

Die perkutane Nephrolithotomie
1985
Zu einem Zeitpunkt, als sich die extrakorporale Stoswellenlithotripsie noch in einem experimentellen und klinischen Versuchsstadium befand, wurde die perkutane Nephrolithotomie als neues Behandlungsverfahren vorgestellt (1). Bei mangelnder allgemeiner Verfugbarkeit von Stoswelleneinrichtungen konnte sie sich in der Folgezeit als alternatives Behandlungsverfahren zur offenen operativen Behandlung von Nieren- und Harnleitersteinen weltweit durchsetzen. Ihr derzeitiger Stellenwert mus in Relation zu den Behandlungsmoglichkeiten, die die Stoswellenlithotripsie und auch andere endourologische Masnahmen wie die Ureterorenoskopie bieten, definiert werden.
Scattering in Strong Magnetic Fields
1985
Publisher Summary This chapter discusses collision processes in the presence of a strong magnetic field. The chapter deals with the potential scattering in a magnetic field arising in connection with the problem of Bremsstrahlung (“free–free transitions”) of an electron in the field. An expression for the photoionization cross section of a one-electron (hydrogenic) system in a magnetic field is also presented. A different approach is required to the problem of ion–atom collisions in a magnetic field because the collision energy E is generally much greater than hωc. Within the two-state model, not only did the magnetic field modify the bound-state wave functions, but, more importantly, it in…

Senza Piano la Sicilia non viaggia
1985
the article analyzes the powers of the Regions in the transport sector, including the competence of the Sicily Region, which despite its specialty in the matter has only a concurrent legislative power with the State. Starting from this data, it is found that without a general transport plan, the Region cannot implement any infrastructure and transport systems, but always on the basis of a frame law that indicates its fundamental principles

Helium bubbles in alpha-irradiated aluminium: positron lifetime studies
1985
The formation of He-stabilised voids in aluminium single crystals injected with helium is monitored by positron lifetime measurements. The bubbles are observed to grow during annealing from 300 to 930K. The bubbles are extremely stable and survive annealing up to the melting point. Positron lifetime data are used to discuss the He density inside the bubbles and their growth mechanism.

Eino Leino ja Italia : tutkimus kulttuurivaikutuksesta ja -vaikutteista
1985
Towards the end of the 19th century Finnish writers discovered Italian literature and also ltaly, the country. Several of them have had a marked effect on Finnish-Italian cultural relations, but of them, Eino Leino's contribution is the most significant in this regard, since he made a translation of the whole of Dante's "Divine Comedy" (1912-1914), thereby earning himself a permanent -position in Italo-Finnish literary relations. Leino was in Italy in the winter of 1908-1909. This trip had a profound effect in the writing of Leino's novel "Onnen orja" ("Slave of Happiness") (1913), this being the first Finnish novel with Italy as the milieu. In "Onnen orja", as in ali the novels of the slav…
