Dans la psychose la forclusion du Nom du père a essentiellement pour effet : l’absence d’identification à la personne qui fait couple sexuel avec la mère, ce qui laisse l’image moïque supportée uniquement par la jouissance d’une mère, A préalable l’absence d’unification des interdits, ce qui laisse la castration dans le Réel, comme une « divination ». Au registre du Réel le sujet répond dans le registre de la foi : à sa jouissance absolue de la Chose il répond par l'Unglauben, la non croyance. Il la rejette en bloc. Il reconstruit dans son délire, sa position passive d’objet de jouissance d’un A préalable.

Stereoscopic Observation

A staining method has been devised for easy en bloc staining for stereoscopic observation of epoxy resin Quetol 651-embedded thick sections under a 300 kV transmission microscope (TEM). In order to enhance staining properties in thick section, osmium tetroxide-fixed tissue blocks are stained only en bloc, since the images of both sides in thick section give high contrast and the image of an intermediate layer shows low contrast by double staining.This method uses carbohydrazide (Polysciences, Inc., U.S.A.) as osmium bridging agent, and both osmium tetroxide and uranyl acetate as electron staining agents.The following procedure is suitable for en bloc staining. 1.Fix small tissue blocks in 2% cacodylate-buffered osmium tetroxide (pH 7.4) for 3 hours at 4°C.2.Wash well in buffer for 1 hour.3.Transfer in 1% aqueous carbohydrazide for 2 hours at room temperature.4.Wash well in distilled water for 1 hour.5.Stain in 1% aqueous osmium tetroxide for 2 hours at room temperature.6.Wash well in distilled water for 1 hour.7.Dehydrate in 50% alcohol for 1 hour.8.Stain in a 2.5% solution of uranyl acetate in 50% alcohol for 3 hours at room temperature.9.Wash in 50% alcohol for 1 hour.10.Dehydrate with 60%, 70%, 80%, 90% and 100% (2 changes) alcohols for 30 minutes each.11.Embed in a mixture of Quetol 651 (Nissin EM Co., Ltd., Japan), nonenyl succinic anhydride, methyl nadic anhydride and DMP-30 according to the method of Kushida et al.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.

AbstractThis paper deals with a possibility to use the ground-based method of observation in order to solve basic problems connected with the solar corona research. Namely:1.heating of the solar corona2.course of the global cycle in the corona3.rotation of the solar corona and development of active regions.There is stressed a possibility of high-time resolution of the coronal line photometer at Lomnický Peak coronal station, and use of the latter to obtain crucial observations.

AbstractThe occurrence of LDE-type flares in the last three cycles has been investigated. The Fourier analysis spectrum was calculated for the time series of the LDE-type flare occurrence during the 20-th, the 21-st and the rising part of the 22-nd cycle. LDE-type flares (Long Duration Events in SXR) are associated with the interplanetary protons (SEP and STIP as well), energized coronal archs and radio type IV emission. Generally, in all the cycles considered, LDE-type flares mainly originated during a 6-year interval of the respective cycle (2 years before and 4 years after the sunspot cycle maximum). The following significant periodicities were found:• in the 20-th cycle: 1.4, 2.1, 2.9, 4.0, 10.7 and 54.2 of month,• in the 21-st cycle: 1.2, 1.6, 2.8, 4.9, 7.8 and 44.5 of month,• in the 22-nd cycle, till March 1992: 1.4, 1.8, 2.4, 7.2, 8.7, 11.8 and 29.1 of month,• in all interval (1969-1992):a)the longer periodicities: 232.1, 121.1 (the dominant at 10.1 of year), 80.7, 61.9 and 25.6 of month,b)the shorter periodicities: 4.7, 5.0, 6.8, 7.9, 9.1, 15.8 and 20.4 of month.Fourier analysis of the LDE-type flare index (FI) yields significant peaks at 2.3 - 2.9 months and 4.2 - 4.9 months. These short periodicities correspond remarkably in the all three last solar cycles. The larger periodicities are different in respective cycles.

The discussion was separated into 3 different topics according to the separation made by the reviewer between the different periods of waves observed in the sun :1) global modes (long period oscillations) with predominantly radial harmonic motion.2) modes with large coherent - wave systems but not necessarily global excitation (300 s oscillation).3) locally excited - short period waves.

Blue Coloration

Uranyl acetate has been used as an electron stain for en bloc staining as well as for staining ultrathin sections in conjunction with various lead stains (Fig. 1). Present studies reveal that various platinum compounds also show promise as electron stains. Certain platinum compounds have been shown to be effective anti-tumor agents. Of particular interest are the compounds with either uracil or thymine as one of the ligands (cis-Pt(II)-uracil; cis-Pt(II)-thymine). These compounds are amorphous, highly soluble in water and often exhibit an intense blue coloration. These compounds show enough electron density to be used as stains for electron microscopy. Most of the studies are based on various cell lines (human AV, cells, human lymphoma cells, KB cells, Sarcoma-180 ascites cells, chick fibroblasts and HeLa cells) while studies on tissue blocks are in progress.

Chorioallantoic Placenta

By routine EM preparative techniques, the tissues which, collectively, separate maternal and fetal bloods in the fully formed chorioallantoic placenta of the rat have been shown to consist of three chorionic layers, or trophoblast, and a layer of allantoic capillary endothelium [Fig. 1]. Relationships between these layers are best demonstrated by special techniques, viz., cacodylate-buffered aldehyde fixation, collidine-buffered osmium tetroxide postfixation, and en bloc staining with uranyl acetate. By using this method on placentas at term, the cells of the outermost chorionic layer (Trophoblast 1) appear to be attached to each other by means of maculae adherentes which sometimes occur in clusters [Fig. 2].

Fluorescent Antibody Method

Localization of amylase,chymotrypsinogen and trypsinogen in pancreas was demonstrated by Yasuda and Coons (1966), by using fluorescent antibody method. These enzymes were naturally found in the zymogen granules. Among them, amylase showed a diffuse localization around the nucleus, in addition to the zymogen granules. Using ferritin antibody method, scattered ferritin granules were also found around the Golgi area (Yasuda et al.,1967). The recent advance in the tissue preparation enables the antigen to be localized in the ultrathin frozen sections, by applying the labeled antibodies onto the sections instead of staining the tissue en bloc.The present study deals with the comparison of the localization of amylase and lipase demonstrated by applying the bismuth-labeled, peroxidase-labeled and ferritin-labeled antibody methods on the ultrathin frozen sections of pancreas, and on the blocks of the same tissue.
