This book was released on 2012-12-06 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiography, the use of penetrating radiation to produce shadow images of the internal structure of materials, has been with us since Roentgen made his discovery of x rays in 1895. However, applications of radiography in the earth sciences and in the related field of soils engineering have, until recent ly, been slow to develop. Bruhl reported optimistically on applications in paleontology as early as 1896 and there have been additional reports through the years. However, very few paleontologists adopted the method and the significant literature is relatively restricted. In soil mechanics, Gerber observed the movement oflead pellets in sand during a plate-bearing test as early as 1929. Gradual ly, radiography was applied to other tests including those on footings, compaction of soils, strain in sand, effects of pile penetration, and displace ments under moving wheel loads. Recently, such work has broadened into much varied and sophisticated research. Applications in geology may be dated to Hamblin's work on rocks re ported in 1962. His demonstration that many fine textural and structural details can be observed in slices of rock led to experimentation by others on unconsolidated sediments and soils. Work is now expanding at an un precedented rate. In some operations, such as the logging of oceanographic cores, it is already a routine process. The advantages of radiography lie in its nondestructive nature and its ability to reveal features that sometimes cannot be seen in any other way.

Download or read book The Effects of Geological Features on Soil Strength written by E. L. Krinitzsky and published by . This book was released on 1970 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray examinations of fine-grained soils from the Lower Mississippi Valley revealed numerous geologic features that are not visible to the unaided eye. These features include significant fracture patterns, details of planar bedding, cross-laminations and turbulence, secondary mineralizations, root penetrations and voids left by roots, the presence of disseminated organic matter and other details. These geologic features affect the strength properties of the soils in which they occur. Experiments with multiple specimens from single samples embodying different features demonstrated that many large variations in strength properties were not only directly dependent of these features but were predictable in a relative sense. Normally, these features are never identified during routine soils testing although the effects of these features contribute to erratic test results. Pretest radiographic examination is a potential means of avoiding these problems. (Author).

Book excerpt: Focussing on the basic mechanics and underlying physics of granular material, Mechanics of Granular Matter starts with an introduction to contact mechanics of individual particles before moving on to a discussion of the structure of force chain networks and the influence on bulk mechanical properties of granular solids and granular flows. Furthermore, a preliminary multi scale framework is proposed for the nonlinear mechanics and strain localization in granular materials.
Download or read book New Directions in Archaeological Science written by Andrew S. Fairbairn and published by ANU E Press. This book was released on 2009-02-01 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Archaeological Science meetings will have a personality of their own depending on the focus of the host archaeological fraternity itself. The 8th Australasian Archaeometry meeting follows this pattern but underlying the regional emphasis is the continuing concern for the processes of change in the landscape that simultaneously effect and illuminate the archaeological record. These are universal themes for any archaeological research with the increasing employment of science-based studies proving to be a key to understanding the place of humans as subjects and agents of change over time. This collection of refereed papers covers the thematic fields of geoarchaeology, archaeobotany, materials analysis and chronometry, with particular emphasis on the first two. The editors Andrew Fairbairn, Sue O'Connor and Ben Marwick outline the special value of these contributions in the introduction. The international nature of archaeological science will mean that the advances set out in these papers will find a receptive audience among many archaeologists elsewhere. There is no doubt that the story that Australasian archaeology has to tell has been copiously enriched by incorporating a widening net of advanced science-based studies. This has brought attention to the nature of the environment as a human artefact, a fact now more widely appreciated, and archaeology deals with these artefacts, among others, in this way in this publication.

Download or read book Ceramics and Society written by Valentine Roux and published by Springer. This book was released on 2019-02-14 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pottery is the most ubiquitous find in most historical archaeological excavations and serves as the basis for much research in the discipline. But it is not only its frequency that makes it a prime dataset for such research, it is also that pottery embeds many dimensions of the human experience, ranging from the purely technical to the eminently symbolic. The aim of this book is to provide a cutting-edge theoretical and methodological framework, as well as a practical guide, for archaeologists, students and researchers to study ceramic assemblages. As opposed to the conventional typological approach, which focuses on vessel shape and assumed function with the main goal of establishing a chronological sequence, the proposed framework is based on the technological approach. Such an approach utilizes the concept of chaîne opératoire, which is geared to an anthropological interpretation of archaeological objects. The author offers a sound theoretical background accompanied by an original research strategy whose presentation is at the heart of this book. This research strategy is presented in successive chapters that are geared to explain not only how to study archaeological assemblages, but also why the proposed methods are essential for achieving ambitious interpretive goals. In the heated debate on the equation stating that “pots equal people”, which is a rather fuzzy reference to assumed relationships between (mostly) ethnic groups and pottery, technology enables us to propose with conviction the equation “pots equal potters”. In this way, a well-founded history of potters is able to achieve a much better cultural and anthropological understanding of ancient societies.
