Physiological Systems in Insects discusses the roles of molecular biology, neuroendocrinology, biochemistry, and genetics in our understanding of insects. All chapters in the new edition are updated, with major revisions to those covering swiftly evolving areas like endocrine, developmental, behavioral, and nervous systems. The new edition includes the latest details from the literature on hormone receptors, behavioral genetics, insect genomics, neural integration, and much more. Organized according to insect physiological functions, this book is fully updated with the latest and foundational research that has influenced understanding of the patterns and processes of insects and is a valuable addition to the collection of any researcher or student working with insects. There are about 10 quintillion insects in the world divided into more than one million known species, and some scientists believe there may be more than 30 million species. As the largest living group on earth, insects can provide us with insight into adaptation, evolution, and survival. The internationally respected third edition of Marc Klowden's standard reference for entomologists and researchers and textbook for insect physiology courses provides the most comprehensive analysis of the systems that make insects important contributors to our environment.

Because they meet the needs of today’s consumers, fresh-cut plant products are currently one of the hottest commodities in the food market of industrialized countries. However, fresh-cut produce deteriorates faster than the correspondent intact produce. The main purpose of Fresh-Cut Fruits and Vegetables: Technology, Physiology, and Safety is to provide helpful guidelines to the industry for minimizing deterioration, keeping the overall quality, and lengthening the shelf life. It provides an integrated and interdisciplinary approach for accomplishing the challenges, where raw materials, handling, minimal processing, packaging, commercial distribution, and retail sale must be well managed. It covers technology, physiology, quality, and safety of fresh-cut fruits and vegetables. In this book, the chapters follow a logical sequence analyzing most of the important factors affecting the main characteristics of fresh-cut horticultural products. The most relevant technologies to prevent deterioration and improve final overall quality of fresh-cut commodities are described in detail. This book covers the basics of the subject from quality preservation, nutritional losses, physiology, and safety to industry-oriented advancements in sanitization, coatings, and packaging. It examines such novel preservation technologies as edible coatings, antimicrobial coatings, natural antimicrobials, gum arabic coatings, and pulsed light treatments. Minimal processing design and industrial equipment are also reviewed. With its international team of contributors, this book will be an essential reference work both for professionals involved in the postharvest handling of fresh-cut and minimally processed fruits and vegetables and for academic and researchers working in the area.

Gallery Sound

Sound is an integral part of contemporary art. Once understood to be a marginal practice, increasingly we encounter sound in art exhibitions through an array of sound making works in various art forms, at times played to very high audio levels. However, works of art are far from the only thing one might hear: music performances, floor talks, exhibition openings and the noisy background sounds that emanate from the gallery café fill contemporary exhibition environments. Far from being hallowed spaces of quiet reflection, what this means is that galleries have swiftly become very noisy places. As such, a straightforward consideration of artworks alone can then no longer account for our experiences of art galleries and museums. To date there has been minimal scholarship directed towards the intricacies of our experiences of sound that occur within the bounds of this purportedly 'visual' art space. Kelly addresses this gap in knowledge through the examination of historical and contemporary sound in gallery environments, broadening our understanding of artists who work with sound, the institutions that exhibit these works, and the audiences that visit them. Gallery Sound argues for the importance of all of the sounds to be heard within the walls of art spaces, and in doing so listens not only to the deliberate inclusion of sound within the art gallery in the form of artworks, performances, and music, but also to its incidental sounds, such as their ambient sounds and the noise generated by audiences. More than this, however, Gallery Sound turns its attention to the ways in which the acoustic characteristics specific to gallery spaces have been mined by artists for creative outputs, ushering in entirely new art forms.

Edible films and coatings play an important role in the quality, safety, transportation, storage, and display of a wide range of fresh and processed foods. Edible films and coatings, while preventing moisture loss and maintaining quality, prevent spoilage and microbial contamination of foods. The edible film and coating industry is now a multimillion dollar industry. Less than $1 million in 1999, the market has grown to more than $100 million and is expected to grow to $350 million by 2008, according to James Rossman of Rossman Consulting. Pharmaceutical and consumer products have been responsible for the tremendous increase. This growth has produced an enormous amount of scientific articles, patents, and research projects undertaken by members of the food industry, academia, and research institutions. Edible Films and Coatings for Food Applications brings together this vast wealth of scientific knowledge in a systematically organized volume. It examines the science, application, function, and market for edible films and coatings.
