The Fine Structure of Algal Cells is a hybrid between a review and a comprehensive descriptive work on fine structure of algae. Such fine structural data are important for any consideration of the classification of algae and for attempting to analyze their phylogenetic relationships. Fine-structure has provided many vital keys to the understanding of the interrelationships and phylogeny of the algae. Notably, the trend in algal fine structure work is toward use of electron microscopy to try to understand the functions of cells and organelles under both normal and experimental conditions. This book brings together information which has been gathered by electron microscopists. It considers 13 classes of algae: Chlorophyceae, Haptophyceae, Prasinophyceae, Bacillariophyceae, Chloromonadophyceae, Phaeophyceae, Euglenophyceae, Dinophyceae, Eustigmatophyceae, Cryptophyceae, Xanthophyceae, Rhodophyceae, and Chrysophyceae. It covers the main structural features of the various classes and the organelles present in typical cells. The book also describes the algal cell covering, flagella, pyrenoid, eyespot, nucleus, and ejectile organelles,as well as membranes, envelope, and stroma of algal chloroplasts. Lastly, it also explains the algal cell division. This book will help students visualize and compare algal structure, and at the same time provide enough references so that research workers can enter the literature to find out more precise details from the original sources.
Biomedical Applications of Microprobe Analysis
by Peter Ingram, John D. Shelburne, Victor L. Roggli, Ann LeFurgey
1999 · Academic Press
Biomedical Applications of Microprobe Analysis is a combination reference/laboratory manual for the use of microprobe analysis in both clinical diagnostic and research settings. Also called microchemical microscopy, microprobe analysis uses high-energy bombardment of cells and tissue, in combination with high resolution EM or confocal microscopy to provide a profile of the ion, metal, and mineral concentrations present in a sample. This allows insight into the physiology and pathophysiology of a wide variety of cells and tissues.This book describes methods for obtaining detailed information about the identity and composition of particles too small to be seen with the naked eye and describes how this information can be useful in diagnostic and biomedical research. - Up-to-date review of electron microprobe analysis - Detailed descriptions of sample preparation techniques - Recent technologies including confocal microscopy, infrared microspectroscopy, and laser raman spectroscopy - Over 100 illustrations with numerous specific applications - Contributions by world-renowned experts in the field - Brief summary of highlights precedes each chapter
The Impact of Publicity on Corporate Offenders
by Brent Fisse, John Braithwaite
1984 · State University of New York Press
Uncertainty surrounds the use of publicity as a means of controlling corporate crime. On the one hand, some agree with Justice Brandeis's dictum that light is "the best of disinfectants...the most efficient policeman." On the other hand, many believe that corporations' internal affairs are effectively shrouded with a thick fog that prevents the light of public scrutiny from reaching them. The Impact of Publicity on Corporate Offenders is the first study to go beyond the rhetoric, through an examination of corporate experience. Fisse and Braithwaite have carried out a qualitative inquiry concerning 17 large corporations involved in publicity crises. Based mainly on interviews, the inquiry includes company employees and former employees, union officials, officers of government regulatory agencies, competitors, independent accountants, government prosecutors, public interest activists, judicial officers, stockbrokers, and other experts.
Biochemical Techniques in the Heart fully describes classical biochemical measurements of parameters involved in contraction and relaxation in the heart. This fully detailed guide tells you how to make preparations of sarcoplasmic reticulum, sarcolemma, and cardiomyocytes and how to measure sodium-calcium and sodium-hydrogen exchange. Two chapters explain the measurement of the important enzyme sodium-potassium ATPase. This book examines the most widely used tools in experimental cardiology and provides you with the recipe-setting up the technique, procurement of equipment, sample data and calculations, problems and trouble shooting, adapting to other species, modifications, and applicability. Undoubtedly, this text will be a great asset to cardiovascular physiologists, pharmacologists, experimental cardiologists, and students of physiology and pharmacology.
Freshwater algae are among the most diverse and ubiquitous organisms on earth. They occupy an enormous range of ecological conditions from lakes and rivers to acidic peat swamps, inland saline lakes, snow and ice, damp soils, wetlands, desert soils, wastewater treatment plants, and are symbionts in and on many plants, fungi, and animals. In North America, the variety of freshwater habitats colonized by algae is very rich, and offers an enormous and fascinating range of environments for their study. They form the base of most aquatic food webs and are critical to studies of ecosystem health. Algal ecologists and taxonomists play an important role in the understanding of aquatic ecosystems: their biodiversity, productivity, interactions with other organisms, and water quality. This book provides in one volume a practical and comprehensive guide to the genera of freshwater algae known from North America. The format combines the necessary ecological, taxonomic and methodological information for all scientists working in aquatic environments, whether their specialty is in environmental monitoring and water quality assessment, biological composition, ecology, evolution, or molecular biology.Key Features* The first complete accounting of North America's freshwater algal genera in more than 50 years* Includes a guide to the current literature on species identification in each group of algae* High-quality photographs and drawings of more than 770 genera* A clear, easy-to-use introductory key to the diagnostic chapters* Synthetic chapters on freshwater habitats, use of algae in environmental assessment, and control of nuisance algae* Contributions from 27 experts in all areas of freshwater algae* Extensive literature citations* Companion volume of Ecology and Classification of North American Freshwater Invertebrates 2nd edition, edited by Throp and Covich
