Practical Guide to Rotational Moulding, Second Edition

By: Roy J Crawford

Rotational moulding (also called rotomoulding or rotocasting), is a low pressure, high temperature manufacturing process that offers a very competitive alternative to blow moulding, thermoforming and injection moulding for the manufacture of hollow plastic parts. It offers designers the chance to produce relatively stress-free articles, with uniform wall thickness and potentially complex shapes. This second edition of the very popular Practical Guide to Rotational Moulding describes the basic aspects of the process and the latest state-of-the-art developments in the industry. It is completely revised and is extensively illustrated.This guide will be of interest both to students of polymer processing and those who work with rotational moulding equipment.

Practical Guide to Rotational Moulding

By: Roy J Crawford,Mark P Kearns

Practical Guide to Rotational Moulding, Third Edition, takes a step-by-step approach to rotomoulding, covering applications, moulds, machinery, materials, and design. This third edition has been thoroughly revised to include the latest advances, including novel materials and moulds, new products, and automation. The book begins with a chapter that introduces the rotational moulding process, analyses advantages and disadvantages, and explores common applications for rotomoulded products. The subsequent chapters provide detailed, methodical coverage of moulds, machinery, materials, and design for functionality, supported by clear illustrations and diagrams. Finally, challenges and future developments are discussed. This hands-on technical guide helps engineers, designers and practitioners to understand all aspects of rotomoulding, with the aim of producing performant end products and parts, with uniform wall thickness and potentially in complex shapes. The book is also of great interest to professionals across the plastics industry, as well as researchers and advanced students in plastics engineering, industrial design, mechanical engineering, chemical engineering, and materials science and engineering. - Provides a strong fundamental understanding of all aspects of the rotational moulding process, from material to finished product - Offers a highly practical combination of technical content and clear illustrations - Covers the latest developments in rotomoulding, including novel materials and moulds, new products, and automated systems

The Last of a Salty Breed

By: Roy Vaughan

Just as the Romans built roads to create and maintain their empire, so the British ruled the ocean waves with ships, and created the biggest empire the world has seen. The Last of a Salty Breed tells tales about British ships, seamen, and the many millions of folk who were voluntarily or forcibly shipped to the four corners of the world to create new countries. This book takes a conventional, chronological narrative interspersed by interludes between the chapters. They are light-hearted or poignant in nature, in many cases highlighting the high and low points of seafaring, and the harrowing voyages of times past. The author, a former maritime journalist for the New Zealand Herald and a ship deck officer, adds to the narrative his personal experiences and those of his maritime ancestors, who stretch back to the 1700s. The main “characters” are ships and prominent seafarers who made history one way or another, from Elizabethan mariners to present time, and include the author’s long family history of seafaring. “The dual dialogue and the subject a very worthy one, as to my knowledge there is no history of the New Zealand Merchant Navy, only books about ships and individual shipping companies.” – Captain Hamish Ross, editor of “Sea Breezes,” the worldwide magazine of ships and the sea

Chemometrics and Cheminformatics in Aquatic Toxicology

By: Kunal Roy

CHEMOMETRICS AND CHEMINFORMATICS IN AQUATIC TOXICOLOGY Explore chemometric and cheminformatic techniques and tools in aquatic toxicology Chemometrics and Cheminformatics in Aquatic Toxicology delivers an exploration of the existing and emerging problems of contamination of the aquatic environment through various metal and organic pollutants, including industrial chemicals, pharmaceuticals, cosmetics, biocides, nanomaterials, pesticides, surfactants, dyes, and more. The book discusses different chemometric and cheminformatic tools for non-experts and their application to the analysis and modeling of toxicity data of chemicals to various aquatic organisms. You’ll learn about a variety of aquatic toxicity databases and chemometric software tools and webservers as well as practical examples of model development, including illustrations. You’ll also find case studies and literature reports to round out your understanding of the subject. Finally, you’ll learn about tools and protocols including machine learning, data mining, and QSAR and ligand-based chemical design methods. Readers will also benefit from the inclusion of: A thorough introduction to chemometric and cheminformatic tools and techniques, including machine learning and data mining An exploration of aquatic toxicity databases, chemometric software tools, and webservers Practical examples and case studies to highlight and illustrate the concepts contained within the book A concise treatment of chemometric and cheminformatic tools and their application to the analysis and modeling of toxicity data Perfect for researchers and students in chemistry and the environmental and pharmaceutical sciences, Chemometrics and Cheminformatics in Aquatic Toxicology will also earn a place in the libraries of professionals in the chemical industry and regulators whose work involves chemometrics.

Good Hygiene Practices and Their Prevention of Biofilms in the Food Industry

By: Roy Fink

This book highlights the importance of hygiene in the food industry with regard to biofilms, which can be found on the contact materials of various food production facilities, including bakery, brewing, seafood processing, and dairy and meat processing. Good hygiene practices in such facilities can prevent microbial niches and harbourage sites, facilitate cleaning and disinfection, maintain or increase product shelf-life, and improve food safety. This book provides essential information on the updated information on biofilm growth conditions, detection methods, and prevention and control strategies.

Civil War and the Indian Wars

Civil War and the Indian Wars

By: Roy Bird

Many historians of the Indian wars seem to credit the War Between the States as a significant factor in the uprising of numerous tribes during these same years. In fact, the continuous exposure to white civilization, the incursion by whites with modern technology, and an ambiguous government policy had caused frustration as far back as two decades before the Civil War began. This account of some of the conflicts between American Indians and whites from 1861-1865 depicts the struggles among disenfranchised native peoples on the frontier and expansion of a predominantly white culture into the West. While whites fought whites from the Atlantic seaboard to the prairies of Kansas, great nations in Arizona, New Mexico, Utah, Montana, the Dakotas, Colorado, Nebraska, Kansas, Texas, Missouri, and Minnesota struck back at the incursion of white intruders. The book neither condemns nor justifies the actions of either side�rather, it is a thorough, chronological examination of the events and incidents that occurred during these four years. Based on confrontations as they were recorded by contemporary writers and historians, the book is not separated into individual accounts of the conflicts as many historians have previously done. Instead, Bird�s approach is to treat all the Indian wars fought between 1861 and 1865 in order of their occurrence to examine the government�s and the military's policies toward the "wild" American Indians of the West.
