This is intended to be a reference manual for Geotechnical Engineers. It is principally a data book for the practicing Geotechnical Engineer and Engineering Geologist, which covers:

• The planning of the site investigation.

• The classification of soil and rock.

• Common testing, and the associated variability.

• The strength and deformation properties associated with the test results.

The Q-system was developed at NGI between 1971 and 1974 (Barton et al. 1974). Since the introduction of the Q-system in 1974 there has been a considerable development within support philosophy and technology in underground excavations. Several new types of rock bolts have been introduced, and the continuous development of fi bre reinforced technology has in many ways changed the support procedure. Application of sprayed concrete has gained acceptance even for good quality rock masses due to demands for a higher level of safety during the recent years. Reinforced ribs of sprayed concrete have replaced cast concrete structures to a large extent.

The aim of this book is to provide reliable information not only on the science of crystallization from solution and from melt but also on the basic design methods for laboratory and especially industrial crystallizers. Up to now the niche between scientific results and practical design and operation of large-scale crystallizers has scarcely been filled. A work devoted to this objective has to take into account relevant crystallization phenomena as well as chemical engineering processes such as fluid dynamics, multiphase flow, and heat and mass transfer. In the design of crystallizers, experiments are initially performed on laboratory crystallizers to obtain kinetic data. In this book, information is given on reliable scale-up of such crystallizers.

FOREGS (Forum of European Geological Surveys) Geochemical Baseline Programme has been initiated to provide high quality environmental geochemical baseline data for Europe. The data will be based on samples of stream water, stream sediment, floodplain sediment, soil, and humus collected all over Europe. High quality and consistency of the obtained data are ensured by using standardised sampling methods and by treating and analysing all samples in the same laboratories.
This programme represents the European contribution to the International Union of Geological Sciences (IUGS)/ International Association of Geochemistry and Cosmochemistry (IAGC) Working Group on Global Geochemical Baselines. The sampling instructions are based on the recommendations of the IGCP 259 and IGCP 360 programmes.
The present report contains comprehensive instructions for sample site selection and sample collection. In addition, a summary of methods intended for sample preparation and analysis is included.

The New Manual of Seismological Observatory Practice (NMSOP or "the Manual") is an initiative of the former Commission on Practice (CoP) of the International Association ofSeismology and Physics of the Earth Interior (IASPEI). At its meeting in conjunction with the IASPEI General Assembly in Wellington, New Zealand, January 1994, the CoP established a Working Group on the Manual of Seismological Observatory Practice. Peter Bormann agreed to chair the group. A first concept for the NMSOP was put forward at the General Assembly of IASPEIís European Seismological Commission (ESC) in Athens, Greece, September 1994 (Bormann, 1994).

Well control problems are always interesting. The raw power that is released by nature in the form of an oil or gas well blowing out of control is awesome. Well control is one thing and WILD well control is something else.

My first experience in applying borehole geophysics to the environmental field was in 1960 at the Idaho National Engineering Laboratory (INEL); however, I started working with geophysical logs in 1953. In Idaho we were able to map a complex aquifer system and the distribution of plumes of waste from injection wells and ponds. One of the earliest applications of neutron moisture logs to locate waste migrating above the water table and of gamma-spectral logs to identify migrating radioisotopes was at the INEL. While at the INEL I was involved in the recovery operations and investigations at the SL-1 reactor.

The mining industry is in a state of flux, and while some may say this has been the norm for many centuries, even the most cursory examination will reveal that the storm waves are real and the need for change within some areas is long overdue. Indeed, the industry is currently facing some serious challenges, including regulatory interference, social isolation, and/or untenable commercial purgatory. However, it warrants recognition that the current waves of opposition ultimately may be only temporary. The industry—and indeed humanity in general—has always adapted to and overcome the challenges of a particular moment, whether measured in the evolution from pig iron to mini-mills or handcarts to electrically driven autonomous haulage.
