Differentiation and Development is the 15th volume in the continuing series under the title "Miami Winter Symposia". This volume summarizes the progress in selected areas of biochemistry and the insights into the molecular basis of biological phenomena. It is divided into 92 chapters that cover topics that represent logical sequel to previous symposia on cloning and genetic manipulation of recombinant DNA.
The introductory chapters discuss the discovered RNA phages with particular emphasis on the use of specific and transformed cells to study cell formation and differentiation. Then, the developmental regulation of protein synthesis and hierarchical controls of nucleolar synthetic functions are discussed. This volume also explains the relationship between cellular events, as well as DNA folding and histone organization in chromatin. The effects of phage infection, DNA damage repair in mycoplasmas, and multiple chorion structural genes are also presented.
This volume looks into the biological features occurring frequently in cell development and differentiation. It studies differentiation and development of various cancer cells and role of several biomolecules in these processes. It also discusses the 3-D structure of a DNA unwinding protein and the role of prostaglandins in cell proliferation and differentiation. The book explains milk proteins and genes during lactogenesis and induction of surface immunoglobulins by lipopolysaccharides. It also examines the genetic control of milk zinc availability and the development of adult muscles in Drosophila abdomen.
The concluding chapters discuss the embryonic gene regulation and biochemical markers for hematopoietic cell differentiation. The origin and significance of tissue-specific histone variant patterns in mammals are explained. Finally, the book covers DNA sequence analysis of chicken ovalbumin gene.

Diffraction and Imaging Techniques in Material Science reviews recent developments in diffraction and imaging techniques used in the study of materials. It discusses advances in high-voltage electron microscopy, low-energy electron diffraction (LEED), X-ray and neutron diffraction, X-ray topography, mirror electron microscopy, and field emission microscopy.
Organized into five parts encompassing nine chapters, this volume begins with an overview of the dynamical theory of the diffraction of high-energy electrons in crystals and methodically introduces the reader to dynamical diffraction in perfect and imperfect crystals, inelastic scattering of electrons in crystals, and X-ray production. It then explores back scattering effects, the technical features of high-voltage electron microscopes, and surface characterization by LEED. Other chapters focus on the kinematical theory of X-ray diffraction, techniques and interpretation in X-ray topography, and interpretation of the contrast of the images of defects on X-ray topographs. The book also describes theory and applications of mirror electron microscopy, surface studies by field emission of electrons, field ionization and field evaporation, and gas-surface interactions before concluding with a discussion on lattice imperfections.
Scientists and students taking courses on diffraction and solid-state electron microscopy will benefit from this book.

A fin de evaluar la posibilidad de reducir costos de alimentación en cultivo de Ramdia quelen, se realizaron dos ensayos experimentales. Uno orientado al cálculo de la digestibilidad in vivo de diferentes dietas con el fin de analizar como afecta el remplazo de la harina de pescado en su digestibilidad proteica. Por otro lado, un ensayo de crecimiento en jaulas para calcular su desempeño productivo. Ambas experiencias fueron realizadas en el Centro Nacional de Desarrollo Acuícola (provincia de Corrientes, 27°32´S,58°30´W)utilizando dos dietas experimentales (15 y 11 por ciento de harina de pescado)junto a un Control (20 por ciento). Para los estudios de digestibilidad se utilizó Cr2O3 como marcador inerte, recolectando las heces en tanques cilindro-cónicos de 150 L conectados a una columna de decantación. Sólo fueron observadas diferencias significativas utilizando p=0,1 (P = 0,0764)en los valores de CDA de la proteína obtenidos entre el Control y la D2, sin observarse diferencias entre estas y la D1. La experiencia en campo se desarrolló en jaulas de 1 m3, con peces de un Peso Inicial promedio aproximado de 28 g, a una densidad de 300 individuos/jaula,durante 197 días de cultivo. Los Pesos Finales promediaron 302,81; 287,07 y 273,39 g para las dietas Control, D1 y D2, respectivamente, observando diferencias significativas (P menor a 0.05)en el IPD, la TEP obtenida con la dieta Control superó a la de la D2 (P menor a 0.05)y no observándose diferencias significativas (P mayor a 0.05)en el FCR alcanzado con las diferentes dietas. Al analizarse los rendimientos obtenidos y los costos de las raciones suministradas, puede evidenciarse que si bien a medida que se reemplaza la proteína de origen animal, el precio por tonelada de dieta elaborada se reduce levemente,este se incrementa al analizar el costo del alimento por tonelada de pescado producido debido a un menor desempeño productivo de los peces.

Recent technological advances have created a testing crisis in the electronics industry--smaller, more highly integrated electronic circuits and new packaging techniques make it increasingly difficult to physically access test nodes. New testing methods are needed for the next generation of electronic equipment and a great deal of emphasis is being placed on the development of these methods. Some of the techniques now becoming popular include design for testability (DFT), built-in self-test (BIST), and automatic test vector generation (ATVG). This book will provide a practical introduction to these and other testing techniques. For each technique introduced, the author provides real-world examples so the reader can achieve a working knowledge of how to choose and apply these increasingly important testing methods.

Digital Design and Computer Architecture is designed for courses that combine digital logic design with computer organization/architecture or that teach these subjects as a two-course sequence. Digital Design and Computer Architecture begins with a modern approach by rigorously covering the fundamentals of digital logic design and then introducing Hardware Description Languages (HDLs). Featuring examples of the two most widely-used HDLs, VHDL and Verilog, the first half of the text prepares the reader for what follows in the second: the design of a MIPS Processor. By the end of Digital Design and Computer Architecture, readers will be able to build their own microprocessor and will have a top-to-bottom understanding of how it works--even if they have no formal background in design or architecture beyond an introductory class. David Harris and Sarah Harris combine an engaging and humorous writing style with an updated and hands-on approach to digital design.

· Unique presentation of digital logic design from the perspective of computer architecture using a real instruction set, MIPS.
· Side-by-side examples of the two most prominent Hardware Design Languages--VHDL and Verilog--illustrate and compare the ways the each can be used in the design of digital systems.
· Worked examples conclude each section to enhance the reader's understanding and retention of the material.
· Companion Web site includes links to CAD tools for FPGA design from Xilinx, lecture slides, laboratory projects, and solutions to exercises.
