Very few electron microscopy papers have been published on the atomic structure of the copper oxide based superconductor surfaces. Zandbergen et al. have reported that the surface of YBa2Cu3O7-δ was such that the terminating layer sequence is bulk-Y-CuO2-BaO-CuO-BaO, whereas the interruption at the grain boundaries is bulk-Y-CuO2-BaO-CuO. Bursill et al. reported that HREM images of the termination at the surface are in good agreement with calculated images with the same layer sequence as observed by Zandbergen et al. but with some oxygen deficiency in the two surface layers. In both studies only one or a few surfaces were studied.

Abstract. This article concerns the utility of ego psychoanalytic perspectives in Rorschach interpretation. Psychoanalytic ego psychology focuses on how people cope with events in their lives and how effectively they can meet challenges to their sense of well-being. The way people deal with experienced distress constitutes their defensive style and determines to a large extent what kind of person they are. Adequate defenses against anxiety promote comfortable and productive adjustment, whereas ineffective defenses typically cause adjustment difficulties and susceptibility to psychological disorders. In Rorschach assessment, the nature and effectiveness of a person’s defensive style can often be identified with a sequence analysis that integrates the structural, thematic, and behavioral features in the protocol. In particular, the sequential quality of responses, especially preceding and following instances of cognitive slippage, can help identify causes of upsetting concerns, defensive efforts to alleviating these concerns, and the adequacy of these defensive efforts in restoring equanimity. This interpretive process is illustrated with attention to implications for differential diagnosis and treatment planning in the Rorschach protocol of a 20-year-old suicidal woman.

Abstract The paper presents the validation procedure of the model used in the analysis of the composite blade for the rotor of the ILX-27 rotorcraft, designed and manufactured in the Institute of Aviation, by means of numerical analyses and tests of composite elements. Numerical analysis using finite element method and experimental studies of three research objects made of basic materials comprising the blade structure – carbon-epoxy laminate, glass-epoxy composite made of roving and foam filler – were carried out. The elements were in the form of four-point bent beams, and for comparison of the results the deflection arrow values in the middle of the beam and axial deformations on the upper and lower surfaces were selected. The procedure allowed to adjust the discrete model to real objects and to verify and correct the material data used in the strength analysis of the designed blade.
