Atlas of Drosophila Morphology

Wild-type and Classical Mutants

 

Academic Press, 2013.

ISBNs 9780123846884

Colección: ScienceDirect

Resumen (en inglés):

The Atlas of Drosophila Morphology: Wild-type and Classical Mutants is the guide every Drosophila researcher wished they had when first learning genetic markers, and the tool they wish they had now as a handy reference in their lab research. Previously, scientists had only poor-quality images or sketches to work with, and then scattered resources online - but no single visual resource quickly at their fingertips when explaining markers to new members of the lab, or selecting flies to do their genetic crosses, or hybrids.

This alphabetized guide to Drosophila genetic markers lays flat in the lab for easy referencing. It contains high-resolution images of flies and the appropriate marker on the left side of each page and helpful information for the marker on the facing page, such as symbol, gene name, synonyms, chromosome location, brief informative description of the morphology, and comments on marker reliability. A companion website with updated information, useful links, and additional data provided by the authors complements this extremely valuable resource.

  • Provides an opening chapter with a well-illustrated introduction to Drosophila morphology
  • Features high-resolution illustrations, including those of the most common markers used by Drosophila researchers
  • Contains brief, practical descriptions and tips for deciphering the phenotype
  • Includes material relevant for beginners and the most experienced fly pushers

Auditing in the Food Industry

From Safety and Quality to Environmental and Other Audits

 

Woodhead Publishing, 2001.

ISBNs 9781855734500

Colección: ScienceDirect

Resumen (en inglés): The food industry faces an unprecedented level of scrutiny. Consumers are not only concerned with the safety and quality of food products but also the way in which they are produced. At the same time the food industry has developed new ways of assuring appropriate standards for its products and their methods of production, developing systems such as TQM and HACCP to identify and manage key steps in production. These new methods require new skills in auditing. Auditing in the food industry provides an authoritative guide to the range of standards and the auditing skills they demand.

Part one sets the scene with an introductory chapter reviewing developments in standards affecting the food industry. There then follows chapters on how retailers audit their suppliers and how governments have moved from a traditional inspection role to one of 'regulatory verification' with its emphasis on auditing the robustness of a business's own systems for managing safety and quality.

Part two examines the key aspects of safety and quality. A first chapter reviews the ways retailers assess supplier HACCP systems. There is then a chapter reviewing TQM systems that provides a context for a discussion of auditing techniques for HACCP-based quality systems. A final chapter looks at standards governing the analytical methods used in safety and quality control.

Part three considers newer standards that are becoming increasingly important in the food industry. There are chapters on benchmarking an organisation against others as a way of improving performance, auditing the impact of food processing operations on the environment and auditing organic food processing.

Auditing in the food industry is a valuable guide to the range of standards facing the food industry and the ways it can audit, and thus improve the quality of its performance.

Autoradiography for Biologists

 

Academic Press, 1972.

ISBNs 9780122732508

Colección: ScienceDirect

Resumen (en inglés): Autoradiography for Biologists discusses the basic and practical aspects of various autoradiography techniques. It is composed of six chapters; each chapter covers a specific form of autoradiography technique.
Chapter 1 discusses various theoretical aspects of autoradiography, such as radioactive decay, beta-particle absorption, photographic process, sensitivity, and resolving power. Chapters 2 to 6 discuss basic aspects of several forms of autoradiography, including macro-, stripping film, diffusible substances, liquid emulsion, and high resolution autoradiography. Practical and theoretical details of the technique, together with modifications made, are covered in each chapter.
This book will be both an encouragement and a help to people wanting to apply autoradiography to the solution of biological problems.

Avian Biology

Vol. 8

 

Academic Press, 1985.

ISBNs 9780122494086

Colección: ScienceDirect

Resumen (en inglés): Avian Biology,Volume VIII assesses selected aspects of avian biology. It is generally the conceptual descendant of Marshall's earlier treatise,“Biology and Comparative Physiology of Birds,” but is more than simply a revision of it.
This volume consists of two relatively lengthy, diverse chapters that focus on adaptive significance of coloniality in birds and fossil records of birds. In particular, this volume looks into group phenomena related to central place systems, that is, systems in which one or more individuals move to and from a centrally located place in the course of daily activities. It also addresses selective factors that have been suggested to explain why individuals should form colonies rather than disperse within the available foraging space.
This book will be useful as a reference material for advanced students and instructors in this field of interest.

Avian Molecular Evolution and Systematics

 

Academic Press, 1997.

ISBNs 9780124983151

Colección: ScienceDirect

Resumen (en inglés): The use of DNA and other biological macromolecules has revolutionized systematic studies of evolutionary history. Methods that use sequences of nucleotides and amino acids are now routinely used as data for addressing evolutionary questions that, although not new questions, have defied description and analysis. The world-renowned contributors use these new methods to unravel particular aspects of the evolutionary history of birds. Avian Molecular Evolution and Systematics presents an overview of the theory and application of molecular systematics, focusing on the phylogeny and evolutionary biology of birds. New, developing areas in the phylogeny of birds at multiple taxonomic areas are covered, as well as methods of analysis for molecular data, evolutionary genetics within and between bird populations, and the application of molecular-based phylogenies to broader questions of evolution.

Key Features
* Contains authoritative contributions from leading researchers
* Discusses the utility of different molecular markers for questions of avian evolution, involving populations and higher-level taxa
* Applies molecular-based phylogenies of birds and molecular population genetics data to broad questions of organismal and molecular evolution.
* Compares and contrasts molecular and morphological data sets

Bacillus Subtilis

 

Academic Press, 1982.

ISBNs 9780122227011

Colección: ScienceDirect

Resumen (en inglés): The Molecular Biology of the Bacilli, Volume I: Bacillus subtilis focuses on areas of research traditionally investigated in Bacillus subtilis, as well as topics in which outstanding progress has been made. It discusses the sporulation, defective bacteriophage, and transformation of Bacillus subtilis.
Organized into 11 chapters, the book begins with the genetic map of Bacillus subtilis, followed by DNA replication and RNA polymerase of the said species. The book then describes the translational apparatus of Bacillus subtilis. It also explains the genetic transformation in Bacillus subtilis; the sporulation genes; the regulatory mechanisms in the development of lytic bacteriophages in this species; the temperate Bacillus subtilis phages; the specialized transduction in Bacillus subtilis; and molecular cloning in this organism. Lastly, the book considers the most economically important areas of the microbiological industry employing bacilli, including the production of enzymes, nucleosides, riboflavin, and preparations pathogenic to insects.
This book will be useful to scientists who are concerned with the use of Bacillus subtilis as a tool for the study of molecular biology and to those who wish to increase the medical, veterinary, and industrial usefulness of this and related organisms.
