Most information about a specimen is obtained by elastic scattering of electrons, but one cannot avoid inelastic scattering and therefore radiation damage by ionisation as a primary process of damage. This damage is a dose effect, being proportional to the product of lectron current density j and the irradiation time t in Coul.cm−2 as long as there is a negligible heating of the specimen.Therefore one has to determine the dose needed to produce secondary damage processes, which can be measured quantitatively by a chemical or physical effect in the thin specimen. The survival of micro-organisms or the decrease of photoconductivity and cathodoluminescence are such effects needing very small doses (see table).

Is it possible to speak of conceptual conjunctions between Fritz Morgenthaler and Jacques Lacan? This question is explored in relation to the practical work of an analyst as she engages with their – at once completely different and yet complementary – theoretical perspectives. Both emphasize the active, demanding-desiring position of the analyst while simultaneously refusing any metapsychologically oriented interpretive technique. Both criticize the normative, denigrating impetus of too much psychoanalytic thinking, especially in the context of developmental psychology and pathologizing doctrine. They warn against too-certain knowledge on the analyst's part. Both emphasize primary-process drive-strivings and the emancipatory possibilities of psychoanalysis – as they both also attend particularly to the formal aspects of the analysand's speech.

Laser polishing is a finishing process based on melting material, with the objective of improving surface topography. Some operating parameters must be taken into consideration, such as laser power, feed rate, offset, and overlapping. Moreover, because of its dependence on the primary process, the initial topography has also an impact on the final result. This study describes a quadratic model, conceived to optimize final topography according to the primary process and laser polishing. Based on an experimental matrix, the model takes into account both laser operating parameters and the initial topography, in order to predict polished surfaces and to determine optimal set of parameters. After the phase of experimentation and the creation of the quadratic model, an optimal final topography is introduced, taking into account the initial surface and the laser parameters.
