Decorative tattoos including permanent make-up are very popular world-wide. As the trend for tattoo acquisition increases, the demand for tattoo removal will similarly rise. This article highlights the state of the art and new developments in laser assisted tattoo removal.

This section of the issue of Geophysics is draw from a collection of papers originally submitted for a monograph on engineering and groundwater geophysics. It is a mixture of tutorial, new developments, and case histories focused on seismic methods. This introduction will review the evolution of this section and introduce each of the papers. These papers complement the overview presented by Dobecki and Romig (1985) in the Golden Anniversary Issue of Geophysics. That paper reviews the history, summarizes the state of the art, and attempts to predict possible future developments.

Summary The aim of this paper is to provide an overview of the ‘state of the art of QDA or CAQDAS software. The author uses Kahneman’s ideas about slow and fast thinking as a framework. Slow thinking in the context of CAQDAS is related to researcher driven analysis and fast thinking to tool- and data driven analysis. The paper is divided into two parts. In the first part, the author describes trends and new developments and in the second part, she offers a critical appraisal.


The papers presented at this meeting have given us a comprehensive account of the state of the art in what one is tempted to call ‘forest meteorology’ though ‘meteorological forestry’ is probably nearer the mark. Older members of the audience like myself who can recall the descriptive and anecdotal nature of the subject in the early 1950s have enjoyed hearing how it has come of age through the painstaking collection of measurements in the field and through the emergence of principles that have guided the development of mathematical models. Forest meteorologists have been fortunate that much of the foundation of their subject has been laid by the pioneers of agricultural meteorology who have had an easier task experimentally and are therefore a little ahead, but not much! A psychologist might have felt quite at home at this meeting because there have been so many references to the way systems ‘behave’. It seemed that systems were ‘well behaved’ when processes being observed were consistent with theoretical predictions where they existed, or with intuition where they did not. Bad behaviour (by a forested catchment in Rob Roy’s territory for example) meant a discrepancy between performance and expectation. We should remember, however, that the recognition of so-called bad behaviour is the first step towards new developments in most branches of science; and that progress in forest meteorology will depend on the skill and patience of people who feel challenged to tackle the anomalies, the uncertainties and the loose ends that we have heard about yesterday and today.

In accepting an invitation to speak in this symposium all the speakers today are exposing themselves to great hazards, and none more so than me. The capabilities of computers, their variety, the associated instrumentation, are all expanding so rapidly and changes are taking place with such a frequency that we are all inevitably out of date. The mere fact of having to prepare an abstract in March for a meeting in August presents hazards. Who knows what revolution in the state of the art will be announced in the meantime?My own project was started four or five years ago so that we may be considerably behind the times. As time went along we were able to take advantage of some of the new developments in technology but in many cases we were simply too far along to make adjustments. As a result, if one were to ask whether our project should serve as a model or whether we would do it the same way again, the answer would have to be “no.” On the other hand, some of the features are good and may serve as examples for future projects. The reader will have to decide.

Improvement of the hot stamping process is important for reducing processing costs and improving the productivity and tensile properties of final components. One major approach to this has been to conduct all or part of the process at lower temperatures. The present paper reviews the state of the art of hot stamping techniques and their applications, considering the following aspects: (1) conventional hot stamping and its advanced developments; (2) warm stamping approaches in which complete austenitisation is not attained during heating; (3) hot stamping with a lower forming temperature, i.e., low-temperature hot stamping (LTHS); (4) advanced medium-Mn steels with lower austenitisation temperatures and their applicability in LTHS. Prospects for the further development of LTHS technology and the work required to achieve this are discussed.

Various authors have emphasized the spatial information resident in an electron micrograph taken with adequately coherent radiation. In view of the completion of at least one such instrument, this opportunity is taken to summarize the state of the art of processing such micrographs. We use the usual symbols for the aberration coefficients, and supplement these with £ and 6 for the transverse coherence length and the fractional energy spread respectively. He also assume a weak, biologically interesting sample, with principal interest lying in the molecular skeleton remaining after obvious hydrogen loss and other radiation damage has occurred.
