  • Restoration and Rehabilitation of the Desert Environment

    • 1st Edition
    • N. Al-Awadhi + 2 more
    • English
    These proceedings contain technical papers presented at the Kuwait-Japan Symposium on Restoration and Rehabilitation of the Desert Environment, which was held in Kuwait on 3-4 March, 1996. Kuwait was selected as the site for this fourth symposium because of its enormous need for restoring and rehabilitating its desert environment, and because of the progress which Kuwait and Japan have been making collectively in these efforts at both pilot and field-scale levels. Kuwait's desert land has recently suffered from one of the worst man-made disasters of all time, having been polluted with vast amounts of oil from the nearly 7000 oil wells that were destroyed during the Gulf War.The three themes for the symposium were: remediation of the polluted soil; enhancement of the visual impact of greenery; and recycling of wastewater for rehabilitation purposes. The first theme was highlighted with presentations on the KISR/PEC Oil-Lake Beds Remediation Project. The second theme was launched with a broad-based discussion on new strategies and alternatives for greening the desert and a summary of the Kuwait National Greenery Plan which is now being prepared. The third theme featured presentations on water resource management in Japan and in KISR's Reverse Osmosis Project to make municipal wastewater recyclable for greenery use in densely populated areas. The closing session culminated in perspectives and recommendations from both Kuwait and Japan and with a historical summary of the long-standing Kuwait/Japan Collaborative Program.

  • Polypropylene and other Polyolefins

    Polymerization and Characterization
    • 1st Edition
    • Volume 7
    • S. van der Ven
    • English
    This book deals with polyolefins prepared via Ziegler-Natta catalysis, from a polymer chemist's viewpoint, i.e. with emphasis on their preparation and on their basic composition and properties. In addition to chapters on catalysts, polymerization behaviour and polymer properties such as tacticity, crystallinity, morphology etc., a chapter is also devoted to characterization methods. The main part of this work is reserved for polypropylene in all its forms, namely, homopolymer, random copolymer and toughened (`block') copolymers, for which extensive own-experience was present. The other polyolefins are also covered by means of a thorough literature review.This book is intended for scientists active in the field of polyolefins, including catalyst development, but should also prove an invaluable medium in academia to illustrate the growth of understanding in catalysis, kinetics and characterization of a commercially very important class of polymers.

  • Geostatistical Ore Reserve Estimation

    • 1st Edition
    • M. David
    • English
    Developments in Geomathematics, 2: Geostatistical Ore Reserve Estimation focuses on the methodologies, processes, and principles involved in geostatistical ore reserve estimation, including the use of variogram, sampling, theoretical models, and variances and covariances. The publication first takes a look at elementary statistical theory and applications; contribution of distributions to mineral reserves problems; and evaluation of methods used in ore reserve calculations. Concerns cover estimation problems during a mine life, origin and credentials of geostatistics, precision of a sampling campaign and prediction of the effect of further sampling, exercises on grade-tonnage curves, theoretical models of distributions, and computational remarks on variances and covariances. The text then examines variogram and the practice of variogram modeling. Discussions focus on solving problems in one dimension, linear combinations and average values, theoretical models of isotropic variograms, the variogram as a geological features descriptor, and the variogram as the fundamental function in error computations. The manuscript ponders on statistical problems in sample preparation, orebody modeling, grade-tonnage curves, ore-waste selection, and planning problems, the practice of kriging, and the effective computation of block variances. The text is a valuable source of data for researchers interested in geostatistical ore reserve estimation.

  • Classifications and Historical Studies

    • 1st Edition
    • Bozzano G Luisa
    • English
    Classifications and Historical Studies is a collection of papers dealing with theoretical and applied ore petrology. One paper discusses the use of conceptual models in geology such as the diagrammatic/pictori... the flow-chart, and the tabular types of conceptualizations. Another paper describes some transitional types of mineral deposits in volcanic and sedimentary rocks. Concentrations of copper minerals and commonly associated metals form deposits associated with orogenic belts and cratonic regions. The paper points out that many major groups of mineral deposits grade into other groups through occurrences with intermediate or transitional characteristics. It suggests a classification method of mineral deposits based on the observable features of the mineral deposits rather than their inferred genesis. One paper reviews the theory of magmatic—hydrotherma... replacement origin of stratiform sulfide ore bodies. The review covers concepts of certain major ore deposits as being independent and isolated phenomena to regarding a wide range of deposits as contemporaneous, indigenous, and related to their environments. Another paper points out that according to North American geologists, certain types of ore deposits are formed syngenetically and are subjected to the same metamorphic events that affect the ores in which they are enclosed. The collection can be valuable to researchers, technical designers, or engineers whose works are related with oil refinery and fossil fuels, as well as to students majoring in geology.

  • Anatomy of Seismograms

    For the IASPEI/Unesco Working Group on Manual of Seismogram Interpretation
    • 1st Edition
    • O. Kulhánek
    • English
    Frequent updating of existing interpretation codes and routines is a prerequisite for modern seismogram interpretation and research. The primary goal of this book is to present in a rather tutorial form all the necessary information and techniques pertinent to essential seismogram interpretation. The treatment is descriptive rather then mathematical, and emphasis is placed on practical aspects, especially for the benefit of students and junior seismogram interpreters affiliated to seismographic stations and observatories. Those workers more knowledgeable in seismology, and curious enough in the detailed deciphering of seismogram peculiarities, will also find the presentation useful.The book is divided into two parts: a verbal description (Chapters 1-6) and a collection of 55 plates (Chapter 7) with interpretations. The verbal description explains in a rather elementary form the most fundamental physical phenomena relevant to seismogram appearance. The collection of plates exhibits a large variety of seismogram examples, and the corresponding interpretations cover different seismic sources (tectonic and volcanic earthquakes, underground explosions, cavity collapse, sonic booms), wave types, epicentral distances, focal depths and recording instruments (analog, digital, short- and long-period, broad band).The book compliments older manuals in that both analog and digital records are considered. Seismograms from more traditional narrow-band as well as from modern, broad-band instruments are displayed. Tectonic and volcanic earthquakes are represented, and the exhibited seismograms form a worldwide collection of records acquired from seismographic stations located in North and Central America, Asia, Europe and New Zealand, i.e. in various geological and tectonic environments. Terminology and usage of definition does vary among agencies in different parts of the world; that used in this book is common to Europe.

  • Stereochemistry of Organometallic and Inorganic Compounds

    • 1st Edition
    • Bozzano G Luisa
    • English
    The authors of this fourth volume in the series have reviewed the making and breaking of chemical bonds in a sophisticated manner. In particular, new pressures brought about by environmental concerns, larger demands for the medical and pharmaceutical sectors and economics of the market place are forcing us into demanding greater stereochemical control and better product yields for chemical reactions capable of producing useful products. The chapters are written by leading experts in this area and give excellent overviews of the strengths and weaknesses of the various methodologies.In Chapter 1 newer discoveries in such tried and true methods of C-C bond formation as alkylations and aldol reactions of metal enolates are reviewed. The author of Chapter 2 discusses the ability of ab-initio methods to justify the results of empirical observations in the field of transition metal derivatives of small molecules such as N2, CO2 and similar small molecules. Having established the strengths and weaknesses of the various approaches to such theoretical calculations, a more interesting approach to these methods is pursued, namely, their ability to predict, in those areas in which they are particularly strong and reliable, chemical and stereochemical events and/or results in advance of experiments, later carried out in the laboratory. Finally, Chapter 3 reviews the stereochemical results of electron transfer reactions in mononuclear copper compounds.

  • Yield Formation in the Main Field Crops

    • 1st Edition
    • Volume 13
    • V. Cerný + 2 more
    • English
    This book gives a detailed overview of production processes and yield formation in field crops and permanent grasslands. Yield formation is discussed by the authors as a dynamic process, involving many factors at each stage. Knowledge of the optimum levels of individual yield components makes it possible to control this dynamic process. It is intended that this approach will help to point out gaps in the understanding of the production processes and indicate the direction for further research on this subject.The authors report on various aspects which are involved in yield formation, such as uptake of nutrients, root growth, water use, photosynthesis, transport, distribution and accumulation of photosynthates, etc. A separate chapter discusses the production process as seen from a genetic standpoint. It includes an analysis of phenotype and genotype with respect to production potential, also the heredity, variability of yield potential and new cultivation methods are mentioned. The main part of the book deals with the theory and practice of yield formation in cereals, maize, legumes, sugarbeet, potatoes, clovers and perennial grass stands.
