Mine Winding and Transport
1st Edition
S.C. Walker
English
Changes in size and power of available mining transport equipment, combined with improved means of control involving leaky feeder radio and computers, demands a new look at the problem of mine winding and transport. Such changes require the traditional mining engineer to have a much greater engineering application. This book is intended to satisfy that requirement.All the important means of transporting operatives and minerals are addressed, both below ground and on the surface. Safe, speedy and economic transport from the point of mineral extraction to leaving the mine is paramount. This work covers all aspects of the problem including: (1) the design and application of steel wire ropes to a variety of industrial applications, and the various drums and pulleys necessary; (2) a ready means of calculating output/throughput of various transport modes, and relating such to their power requirement; and (3) information on transport modes that enables the most suitable system for given conditions to be determined.A ``first principle'' approach has been adopted throughout, and extensive use of practical examples allows the solution of virtually all associated problems. Although formulae are used where necessary for an understanding of the content, the numerous tables included enable the practicing engineer to make short cuts to more quickly solve particular problems. In addition, the provision of a considerable number of operational constants, many not previously published, enable a more speedy and accurate solution to be effected. By comparing the calculated solutions to a particular problem, the most economic transport mode may be determined.Mining, mechanical and electrical engineers concerned with the safe movement of men or material will find this book of particular use, as will the student preparing for examinations on the subject.
Guide-Lines to Planning Atomic Spectrometric Analysis
1st Edition
Volume 4
B. Magyar
English
Studies in Analytical Chemistry, Volume 4: Guide-Lines to Planning Atomic Spectrometric Analysis covers the physico-chemical background of atomic absorption spectrometry (AAS) and atomic emission spectrometry (AES). This book is composed of six chapters and begins with an introduction to the criteria on choosing the best and most suitable method for solving a given analytical problem. The next chapters deal with the properties, generation, and absorption of electromagnetic radiation, as well as the theory of atomic spectra that require knowledge of X-ray. Other chapters discuss the broadening of atomic lines, which is important for understanding that calibration curves in AAS are always bent. A chapter examines the sensitivity of determination by AAS and AES. The last chapter describes the spectrometric measurement of atomic absorption and emission. This chapter also looks into the influence of the design of the monochromator upon the measured emission intensity and calibration curve by AAS. This book will prove useful to analytical chemists and researchers.

English
Developments in Geotechnical Engineering, Vol. 14A: Rockslides and Avalanches, 1: Natural Phenomena focuses on attempts to provide a foundation for studies of mass movement phenomena in the Western Hemisphere. The selection first elaborates on Albert Heim's observations on landslides and relevance to modern interpretations, Frank rockslide in Alberta, Canada, and Lower Gros Ventre slide in Wyoming, U.S.A. Discussions focus on geologic environment, events triggered by rise and fall of slide lake level, description of slide mass and zone of detachment, stability analysis, travel distance of sturzstrom deposits, and geometry of the Elm sturzstrom deposits. The publication then takes a look at Madison Canyon rockslide in Montana, U.S.A., Little Tahoma Peak rockfalls and avalanches in Mount Rainier, Washington, U.S.A., Sherman Glacier rock avalanche in Alaska, U.S.A., and Nevados Huascaran avalanches in Peru. Topics include rockslide kinematics, associated seismic activity, meteorological and hydrological conditions, mode of emplacement of other Alaskan rock avalanches, and applicability of mechanical fluidization to other rock avalanches. The text examines the mechanics of glacier movement, dynamics of snow avalanches, failure of snow slopes, and role of gravity in plate tectonics. The selection is a valuables reference for researchers wanting to study further rockslides and avalanches.
Gap Junctions
1st Edition
J.E. Hall + 2 more
English
Gap junctions are present in nearly all tissues, regardless of their embronic origin and have long been of great interest to scientists from many different disciplines. The international meeting on which this book is based brought together 157 scientists from 12 countries and almost as many scientific disciplines. The papers presented at the meeting were reviewed and updated prior to publication in this book. The seven parts of the book progress from general topics to the more specific ones (role of gap junctions in various tissues, regulation and biochemistry, and cancer).
Handbook of Fatigue Crack Propagation in Metallic Structures
1st Edition
A. Carpinteri
English
The purpose of this Handbook is to provide a review of the knowledge and experiences in the field of fatigue fracture mechanics. It is well-known that engineering structures can fail due to cyclic loading. For instance, a cyclically time-varying loading reduces the structure strength and can provoke a fatigue failure consisting of three stages: (a) crack initiation (b) crack propagation and (c) catastrophic failure. Since last century many scientists have tried to understand the reasons for the above-mentioned failures and how to prevent them. This Handbook contains valuable contributions from leading experts within the international scientific community and covers many of the important problems associated with the fatigue phenomena in civil, mechanical and nuclear engineering.
Engineering Turbulence Modelling and Experiments - 3
1st Edition
G. Bergeles + 1 more
English
This book presents and discussses new developments in the area of turbulence modelling and measurements, with particular emphasis on engineering-related problems. At present, turbulence is one of the key issues in tackling engineering flow problems. Powerful computers and numerical methods are now available for solving the flow equations, but the simulation of turbulence effects which are nearly always important in practice, is still in an unsatisfactory state and introduces considerable uncertainities in the accuracy of CFD calculations. These and other aspects of turbulence modelling and measurements are dealt with in detail by experts in the field. The resulting book is an up-to-date review of the most recent research in this exciting area.

W-Sn Skarn Deposits
and Related Metamorphic Skarns and Granitoids
1st Edition
Volume 24
T.A.P. Kwak
English
Intended as a reference for the academically-oriente... geologist as well as the practising economic geologist, this book is concerned with the study of skarn deposits having anomalously high tin or tungsten contents, or both. Unlike many other books on economic geology, both economic W-Sn skarns and non-economic examples are covered, in order to enable the academically-oriente... reader to grasp the full range of such deposits, and also to aid the economic geologist in distinguishing between W-Sn skarns having economic potential and those which do not.W-Sn skarns are notoriously complex, containing a wide range of textures, grain sizes, mineral assemblages, bulk compositions and structures. The lack of a sufficiently detailed data base, coupled with some unsupportable genetic models, has led to many misunderstandings and has often resulted in needless expenditure and effort on fruitless mineral exploration. Thus, the first aim of this book is simply to provide an adequate data base with sufficient references to enable an interested worker to define a skarn deposit and know where to find additional information on similar examples. To aid this, as much data as possible is presented as tables and diagrams.The second aim of the book is to show the reader how to separate skarn rocks found in W-Sn-bearing environments into those produced by metamorphic, isochemical processes (metamorphic skarns) which are uneconomic, and those produced by the introduction and exchange of components from an ore solution (ore skarn). W-Sn skarns are also separated into genetically logical subdivisions so that, if a deposit or a specific geological environment can be identified, then skarn zonation or the potential of finding specific skarn types can be predicted. This is particularly important to the practising exploration geologist because often only a small part of a skarn or only certain skarn types contain economic mineralization.In addition, the book provides an insight into how to assess where mineralogical complications may occur, especially with respect to Sn-skarns, and in which environments such complications may be expected. It also provides enough information for the reader to be able to conceptualize suitable models for W-Sn skarns based on primary data.
Selected Topics in the History of Biochemistry

1st Edition
Volume 35
G. Semenza
English
Selected Topics in the History of Biochemistry: Personal Recollections, I presents selected topics in the history of biochemistry based on the authors' personal recollections. These topics range from the isolation of Cori ester and the discovery of sugar nucleotides to the work of Frederick Gowland Hopkins (1861-1947). Ion-coupled membrane processes are also discussed, along with fructose and fructose-2,6-bisphos... well as lysosomes and glycogen. Comprised of 12 chapters, this volume begins with the discovery of Cori ester and the concept of phosphorolysis before turning to the discovery of sugar nucleotides and research on ion-coupled membrane processes. The reader is then introduced to studies of fructose, fructose-2,6-bisphos... lysosomes, and glycogen; the contributions of Frederick Gowland Hopkins in biochemistry; and a short autobiography of Juda Hirsch Quastel, with emphasis on his research work on the concept of active centers as a possible explanation of enzyme action and his investigation of the effects of malonic acid and substituted malonic acids on bacterial dehydrogenases. The remaining chapters focus on a biochemist's approach to autopharmacology; the early development of modern protein chemistry in Uppsala, Sweden; and the biographies of two Russian scientists, A. N. Bach and Sergei E. Severin. This monograph will be of interest to students, practitioners, and researchers in the field of biochemistry.
