Paper And Pencil

The paper fills gaps in knowledge about Kuratowski operations which are already in the literature. The Cayley table for these operations has been drawn up. Techniques, using only paper and pencil, to point out all semigroups and its isomorphism types are applied. Some results apply only to topology, and one cannot bring them out, using only properties of the complement and a closure-like operation. The arguments are by systematic study of possibilities.

Spectrum Imaging

As interest for parallel EELS spectrum imaging grows in laboratories equipped with commercial spectrometers, different approaches were used in recent years by a few research groups in the development of the technique of spectrum imaging as reported in the literature. Either by controlling, with a personal computer both the microsope and the spectrometer or using more powerful workstations interfaced to conventional multichannel analysers with commercially available programs to control the microscope and the spectrometer, spectrum images can now be obtained. Work on the limits of the technique, in terms of the quantitative performance was reported, however, by the present author where a systematic study of artifacts detection limits, statistical errors as a function of desired spatial resolution and range of chemical elements to be studied in a map was carried out The aim of the present paper is to show an application of quantitative parallel EELS spectrum imaging where statistical analysis is performed at each pixel and interpretation is carried out using criteria established from the statistical analysis and variations in composition are analyzed with the help of information retreived from t/γ maps so that artifacts are avoided.

Ziele: Formulierung evidenzbasierter Leitlinien, die Screening und Kurzintervention im Rahmen der medizinischen Basisversorgung erleichtern sollen. Methode: Literaturrecherche in der Datenbank MEDLINE und Auswertung der seit 1995 publizierten Studien. Ergebnisse: <OL><LI>Screening: Sensitivität und Spezifität einfacher »Paper and Pencil«-Verfahren sind in der Regel höher als die herkömmlicher biochemischer Marker. <LI>Intervention: Eine minimale Intervention kann zahlreiche Patienten veranlassen, den Konsum von Alkohol zu reduzieren. Kurzinterventionen sind in hohem Maße kosteneffizient.</OL> Schlussfolgerungen: Vor dem Hintergrund der vorliegenden Literatur erscheint die Implementierung sekundärpräventiver Maßnahmen gerechtfertigt.
