Spherical Crystallization as a New Platform for Particle Design Engineering
by Yoshiaki KawashimaThis book describes the principles and applications of the spherical crystallization technique, from the standpoint of its inventor. After an introduction on the history of particle design engineering and nanotechnology, the concept of spherical crystallization itself is clearly explained. Attention then turns to the application of spherical crystallization in pharmaceutical processes. It is explained how the technique can provide physicochemical properties suitable for direct tableting of active pharmaceutical ingredients and how it has enabled the development of a novel particulate design platform from single to complex system. Subsequent chapters describe the roles of polymeric spherical crystallization in the preparation of novel microspheres, microballoons for drug delivery systems (DDS) and the development of biocompatible and biodegradable poly(D,L-lactide-co-glycolide) (PLGA) nanospheres. The various applications of PLGA nanospheres composite within oral-, pulmonary-, transdermal DDS and cosmetics are fully discussed. Finally, future perspectives are presented on use of the technology in the design and industrial-scale manufacture of new drug delivery systems, highlighting how a continuous pharmaceutical process that meets US Food and Drug Administration quality requirements should soon be introduced.

Spic-and-Span!: Lillian Gilbreth's Wonder Kitchen (Great Idea Series #6)
by Monica KullingBorn into a life of privilege in 1878, Lillian Moller Gilbreth put her pampered life aside for one of adventure and challenge. She and her husband, Frank, became efficiency experts by studying the actions of factory workers. They ran their home efficiently, too. When Frank suddenly died, Lillian was left to her own devices to raise their eleven children. Eventually, she was hired by the Brooklyn Borough Gas Company to improve kitchen design, which was only the beginning. Lillian Gilbreth was the subject of two movies (Cheaper by the Dozen and Belles on Their Toes), the first woman elected to the National Academy of Engineering, and the first female psychologist to have a U.S. postage stamp issued in her honor. A leading efficiency expert, she was also an industrial engineer, a psycologist, an author, a professor, and an inventor.

Spices, Scents and Silk: Catalysts of World Trade
by James HancockSpices, scents and silks were at the centre of world trade for millennia. Exotic luxuries such as cinnamon, ginger, pepper, saffron, clove, frankincense and myrrh. Through their international trade, humans were pushed to explore and then travel to the far corners of the earth. Almost from their inception, the earliest great civilizations - Egypt, Sumer and Harappa - became addicted to the luxury products of far-off lands and established long-reaching trade networks. Over time, great powers fought mightily for the kingdoms where silk, spices and scents were produced. The New World was accidentally discovered by Columbus in his quest for spices. What made trade in these products so remarkable was that the plants producing them grew in very restricted areas of the world, distant from the wealthy civilizations of northern Africa, Greece and Europe. These luxuries could be carried from mysterious locations on the backs of camels or in the holds of ships for months on end, and arrived at their final destination in nearly perfect condition. Once the western world discovered the intoxicating properties of these products, their procurement became a dominant force in the world economy. Nothing else compared with their possible profit returns. In this book, eminent horticulturist and author James Hancock examines the origins and early domestication and culture of spices, scents and silks and the central role they played in the lives of the ancients. The book also traces the development of the great international trade networks and explores how struggles for trade dominance and demand for such luxuries shaped the world. Recommended for academics, students and general readers with an interest in crop and agricultural development, world trade, economic botany, history of food, and global economics and public policy, Spices, Scents and Silk offers a fascinating and insightful history.

Spider Behaviour: Flexibility and Versatility
by Marie Elisabeth HerbersteinSpiders are often underestimated as suitable behavioural models because of the general belief that due to their small brains their behaviour is innate and mostly invariable. Challenging this assumption, this fascinating book shows that rather than having a limited behavioural repertoire, spiders show surprising cognitive abilities, changing their behaviour to suit their situational needs. The team of authors unravels the considerable intra-specific as well as intra-individual variability and plasticity in different behaviours ranging from foraging and web building to communication and courtship. An introductory chapter on spider biology, systematics and evolution provides the reader with the necessary background information to understand the discussed behaviours and helps to place them into an evolutionary context. Highlighting an under-explored area of behaviour, this book will provide new ideas for behavioural researchers and students unfamiliar with spiders as well as a valuable resource for those already working in this intriguing field.
Spider Ecophysiology
by Wolfgang NentwigWith over 43,000 species, spiders are the largest predacious arthropod group. They have developed key characteristics such as multi-purpose silk types, venoms consisting of hundreds of components, locomotion driven by muscles and hydraulic pressure, a highly evolved key-lock mechanism between the complex genital structures, and many more unique features. After 300 million years of evolutionary refinement, spiders are present in all land habitats and represent one of the most successful groups of terrestrial organisms. Ecophysiology combines functional and evolutionary aspects of morphology, physiology, biochemistry and molecular biology with ecology. Cutting-edge science in spiders focuses on the circulatory and respiratory system, locomotion and dispersal abilities, the immune system, endosymbionts and pathogens, chemical communication, gland secretions, venom components, silk structure, structure and perception of colours as well as nutritional requirements. Spiders are valuable indicator species in agroecosystems and for conservation biology. Modern transfer and application technologies research spiders and their products with respect to their value for biomimetics, material sciences, and the agrochemical and pharmaceutical industries.

Spider Silk: Evolution and 400 Million Years of Spinning, Waiting, Snagging, and Mating
by Leslie Brunetta Catherine L. CraigSpiders, objects of eternal human fascination, are found in many places: on the ground, in the air, and even under water. Leslie Brunetta and Catherine Craig have teamed up to produce a substantive yet entertaining book for anyone who has ever wondered, as a spider rappelled out of reach on a line of silk, "How do they do that?" The orb web, that iconic wheel-shaped web most of us associate with spiders, contains at least four different silk proteins, each performing a different function and all meshing together to create a fly-catching machine that has amazed and inspired humans through the ages. Brunetta and Craig tell the intriguing story of how spiders evolved over 400 million years to add new silks and new uses for silk to their survival "toolkit" and, in the telling, take readers far beyond the orb. The authors describe the trials and triumphs of spiders as they use silk to negotiate an ever-changing environment, and they show how natural selection acts at the genetic level and as individuals struggle for survival.
Spider Webs: Behavior, Function, and Evolution
by William EberhardIn this lavishly illustrated, first-ever book on how spider webs are built, function, and evolved, William Eberhard provides a comprehensive overview of spider functional morphology and behavior related to web building, and of the surprising physical agility and mental abilities of orb weavers. For instance, one spider spins more than three precisely spaced, morphologically complex spiral attachments per second for up to fifteen minutes at a time. Spiders even adjust the mechanical properties of their famously strong silken lines to different parts of their webs and different environments, and make dramatic modifications in orb designs to adapt to available spaces. This extensive adaptive flexibility, involving decisions influenced by up to sixteen different cues, is unexpected in such small, supposedly simple animals. As Eberhard reveals, the extraordinary diversity of webs includes ingenious solutions to gain access to prey in esoteric habitats, from blazing hot and shifting sand dunes (to capture ants) to the surfaces of tropical lakes (to capture water striders). Some webs are nets that are cast onto prey, while others form baskets into which the spider flicks prey. Some aerial webs are tramways used by spiders searching for chemical cues from their prey below, while others feature landing sites for flying insects and spiders where the spider then stalks its prey. In some webs, long trip lines are delicately sustained just above the ground by tiny rigid silk poles. Stemming from the author’s more than five decades observing spider webs, this book will be the definitive reference for years to come.
