This Geoguide presents a recommended standard of good practice for the description of Hong Kong rocks and soils for engineering purposes. This need was recognized in July 1983, when a Subcommittee of the Building Authority Working Party on Geotechnical Regulations reviewed the application in Hong Kong of the British Standard BS 5930 : 1981, Code of Practice for Site Investigations. With regard t o Section 8 of BS 5930 (Descriptions of Soils and Rocks), the Subcommittee concluded that it should not be recommended for general use in Hong Kong, because parts of the section were not relevant to local conditions or conflicted with current Hong Kong practice.

This book tackles calculus with an infinitesimal approach. The infinitesimal approach has three important advantages for the calculus-learner. First, it is closer to the intuition which originally led to calculus. Second, the central concepts of derivative and integral become easier for the student to understand and use. Third, it teaches both infinitesimal and traditional approaches, giving the student an extra tool which may become increasingly important in the future.
It is important keep in mind that the calculus was originally developed using the intuitive concept of an infinitesimal, or an infinitely small number.
While the traditional course begins with the difficult limit concept, this course/book begins with the more easily understood infinitesimals.
Enjoy it!!!!

NISTIR 6295_Curing of High-Performance Concrete: Report of the State-of-the-Art
Author: Kenneth W. Meeks; Nicholas J. Carino | Size: 1 MB | Format:PDF | Quality:Unspecified | Publisher: NIST | Year: 1999 | pages: 191
This report describes the latest information, technology, and research on the curing of high-performance concrete (HPC). The scope of the report is expanded somewhat to examine the current body of knowledge on the effects of various curing conditions on the development of the properties of concrete in general. The significance and importance of curing and various proposed definitions of high-performance concrete are discussed. Specific types of the most commonly used high-performance concrete are described, and their properties and characteristics are highlighted.
The report summarizes some of the currently accepted concepts and theories of how curing alters the physico-chemical characteristics and structure of a cement paste, since many of these are applicable to the study of high-performance concrete.
The history of the American Concrete Institute (ACI) building code requirements for curing are traced from the beginning of this century to the present time. Current curing requirements in the standards of various countries are reviewed and discussed. Some of the recent research in the United States and other countries, related either directly or indirectly to the curing of high-performance concrete, is summarized.
The report concludes with a discussion of the major areas of research needed to develop optimum curing criteria for this new class of concrete.

This monograph contains original results in the field of mathematical and numerical modeling of mechanical behavior of granular materials and materials with different strengths. It proposes new models helping to define zones of the strain localization. The book shows how to analyze processes of the propagation of elastic and elastic-plastic waves in loosened materials, and constructs models of mixed type, describing the flow of granular materials in the presence of quasi-static deformation zones. In a last part, the book studies a numerical realization of the models on multiprocessor computer systems. The book is intended for scientific researchers, lecturers of universities, post-graduates and senior students, who specialize in the field of the deformable materials mechanics, mathematical modeling and adjacent fields of applied and calculus mathematics.

Nonlinear energy pumping as a strategy for seismic protection. PhD Thesis - Nucera, F., University of Calabria at Arcavacata of Rende, Cosenza, Italy (2005)
he Second International Symposium on Constitutive Modeling of Geomaterials: Advances and New Applications (IS-Model 2012), is to be held in Beijing, China, during October 15-16, 2012. The symposium is organized by Tsinghua University, the International Association for Computer Methods and Advances in Geomechanics (IACMAG), the Committee of Numerical and Physical Modeling of Rock Mass, Chinese Society for Rock Mechanics and Engineering, and the Committee of Constitutive Relations and Strength Theory, China Institution of Soil Mechanics and Geotechnical Engineering, China Civil Engineering Society. This Symposium follows the first successful International Workshop on Constitutive Modeling held in Hong Kong, which was organized by Prof. JH Yin in 2007. Constitutive modeling of geomaterials has been an active research area for a long period of time. Different approaches have been used in the development of various constitutive models. A number of models have been implemented in the numerical analyses of geotechnical structures. The objective of the symposium is to provide a forum for researchers and engineers working or interested in the area of constitutive modeling to meet together and share new ideas, achievements and experiences through presentations and discussions. Emphasis is placed on recent advances of constitutive modeling and its applications in both theoretic and experimental aspects. Six famous scholars have been invited for the plenary speeches of the symposiums. Some prominent scholars have been invited to organize four specialized workshops on hot topics, including “Time-dependent stress-strain behavior of geomaterials”, “Constitutive modeling within critical state soil mechanics”, “Multiscale and multiphysics in geomaterials”, and “Damage to failure in rock structures”. A total of 49 papers are included in the above topics. In addition, 51 papers are grouped under three topics covering “Behaviour of geomaterials”, “Constitutive model”, and “Applications”. The editors expect that the book can be helpful as a reference to all those in the field of constitutive modeling of geomaterials.
