Veterinary Reproduction and Obstetrics TENTH EDITION - Original PDF
نویسندگان: خلاصه: As the standard theriogenology text for veterinary students, Veterinary Reproduction and Obstetrics is also a great reference to keep post-graduation. The 10th edition of this book has been thoroughly updated to include normal reproduction and reproductive disorders, as well as diseases in the common and less common domestic species (dogs, cats, pigs, and horses as well as llamas, alpacas, and camels). This sorely needed information is vital for practicing in underdeveloped countries which lack the technology, equipment, and personnel offered in the U.S. With many international contributing authors, this one-of-a-kind text includes developments in reproductive biology and endocrinology from across the globe.
Principles of Tissue Engineering Fifth Edition - Original PDF
نویسندگان: خلاصه: Now in its fifth edition, Principles of Tissue Engineering has been the definite resource in the field of tissue engineering for more than a decade. The fifth edition provides an update on this rapidly progressing field, combining the prerequisites for a general understanding of tissue growth and development, the tools and theoretical information needed to design tissues and organs, as well as a presentation by the world’s experts of what is currently known about each specific organ system. As in previous editions, this book creates a comprehensive work that strikes a balance among the diversity of subjects that are related to tissue engineering, including biology, chemistry, material science, and engineering, among others, while also emphasizing those research areas that are likely to be of clinical value in the future. This edition includes greatly expanded focus on stem cells, including induced pluripotent stem (iPS) cells, stem cell niches, and blood components from stem cells. This research has already produced applications in disease modeling, toxicity testing, drug development, and clinical therapies. This up-to-date coverage of stem cell biology and the application of tissue-engineering techniques for food production – is complemented by a series of new and updated chapters on recent clinical experience in applying tissue engineering, as well as a new section on the emerging technologies in the field.
Mechanics and Analysis of Composite Materials - Original PDF
نویسندگان: خلاصه: This book is concerned with the topical problems of mechanics of advanced composite materials whose mechanical properties are controlled by high-strength and high-stiffness continuous fibers embedded in polymeric, metal, or ceramic matrix. Although the idea of combining two or more components to produce materials with controlled properties has been known and used from time immemorial, modern composites have been developed only several decades ago and have found by now intensive application in different fields of engineering, particularly, in aerospace structures for which high strength-to-weightand stiffnessto-weight ratios are required.
Fundamentals of Discrete Element Methods for Rock Engineering - Original PDF
نویسندگان: خلاصه: PREFACE This book is a summary of our collaborative teaching and research efforts over the last two decades relating to the subject of discrete element methods (DEM) and its applications to rock mechanics and rock engineering. We have not intended this book to be a thorough presentation of the most current cutting- edge research subjects in the fields of DEM and its applications in geosciences and geoengineering – because the advances are occurring too rapidly. Instead we present some fundamental concepts behind the basic theories and tools of DEM, its historical development and its wide scope of applications in geology, geophysics and rock engineering. We hope that, with this moderate ambition, it may be more helpful and useful for a larger number of practicing engineers, students and researchers alike and serve as a starting platform for more advanced and in-depth further studies. Unlike almost all books available on the general subject of DEM, this book includes coverage of both explicit and implicit DEM approaches, namely the distinct element methods and discontinuous deforma- tion analysis (DDA) for both rigid and deformable blocks and particle systems, and also the discrete fracture network (DFN) approach for fluid flow simulations. Actually the latter is also a discrete approach of importance for rock mechanics and rock engineering. In addition, brief introductions to some alternative approaches are also provided, such as percolation theory and Cosserat micro-mechanics equivalence to particle systems, which often appear hand in hand with the DEM in the literature. We provide a presentation of the fundamentals of the governing equations of the discrete systems concerning motion, deformation, fluid flow and heat transfer, to an extent that is currently considered in some available DEM codes. Special attention is given to constitutive models of rock fractures and fracture system characterization methods. These two issues are the basic building blocks of DEM and also have the most significant impacts on the performance and uncertainty of the DEM models. The DEMs were pioneered and continuously developed by Dr P. A. Cundall, the creator of the distinct element methods, and Dr Genhua Shi, the creator of DDA, block theory and numerical manifold method. The authors learned DEM basics from them and received continuous inspirations and encour- agements. This book presents only some basics of the distinct element methods and discontinuous deformation analysis, only small parts of their outstanding contributions. The first author expresses his special gratitude to Professor Xuefu Yu in China, who led the author into the fields of rock mechanics and numerical modeling in late 1970s and provided continuous guidance and encouragements
Comminution 1994 Proceedings of the 8th European Symposium on Comminution and 50th Event of the European Federation of Chemical Engineering, May 17-19, 1994 Stockholm, Swede - PDF
نویسندگان: خلاصه: Particle arrangements and confinements can be classified in the four groups (1) single particle situation, (2) one-particle layer, (3) particle bed confined closely or widely, and (4) ideal particle bed. Any confinement influences the stress distribution inside the bed due to the wall friction, and a complex stress field arises. The size-reduction effect is represented with the fraction of broken particles, the breakage function and the specific surface increases. The breakage functions of the particle bed comminution display as truncated logarithmic normal distributions. The stressing intensity can be quantified by the pressure, the stress field characteristics or the energy absorption. Although the stress field situation can differ extremely, the overall energy absorption has been proven to represent the stressing intensity very well in respect to the size-reduction. The transition from a close to a moderately wide confinement does not affect the size-reduction strongly. Steel balls inserted in a particle bed improve the breakage of coarse particles at a low intensity level. This advantage fades with increasing intensity and decreasing particle size.
Integral Waterproofing of Concrete Structures - Original PDF
نویسندگان: خلاصه: Concrete is the most popular construction material, which has a widespread range of structural applications, under numerous environmental conditions and under various levels and types of mechanical loads. It is used in buildings, infrastruc- tures, dams etc. Its suitability and durability require a set of mechanical, physi- cal, and chemical characteristics in order to extend its service life. Concrete durability is defined according to Concrete Terminology by American Concrete Institute (ACI) [1], as “the ability of concrete to resist weathering action, chemi- cal attack, abrasion, and other conditions of service.” This performance is simply based on concrete chemistry. Concrete durability properties are determined by its chemical structure and porosity. These structural characteristics are determined by cement components and their reactions with water. Understanding concrete durability problems and solutions requires a sufficient knowledge about concrete chemistry.
Essentials of Flow Assurance Solids in Oil and Gas Operations Understanding Fundamentals, Characterization, Prediction, Environmental Safety, and Managemen - Original PDF
نویسندگان: خلاصه: ntroduction Oil and gas were formed over millions of years from the dead bodies of plankton (tiny marine organ- isms). These prehistoric dead plankton and their naturally engineered product have dominated and shaped modern times into “the Great Oil Age,” as McKenzie-Brown, Jaremko, and Finch titled their book on the subject [1]. Petroleum shapes our modern times in two main ways: first by serving as the main source of energy, and secondly by being the raw material for thousands of products that play critical roles in modern civilization. Fossil fuels still constitute the major global source of energy, despite the recent advances in renew- able sources of energy. Fossil fuels represent 85% of global primary energy consumption [2,3], with oil remaining as the most used source in the energy mix (33%–34%), as shown in Fig. 1.1. The global consumption of and demand for hydrocarbons (oil and gas) outweigh that of other sources of energy such as coal, nuclear, and renewable energies, due to the fast-growing population and newly emerging technologies. The global energy demand is projected to more than double by 2050 due to the growth in population and economies [4]. The demand for gas is growing faster than the demand for oil, especially in developing countries [5,6]
