This book introduces recent progress in stimuli-responsive interfaces constructed on colloidal materials such as micelles and vesicles and on solid material surfaces. There is discussion of the effect of stimuli such as light, heat, pH, and electric field on changes in the morphology of the molecules at the interfaces and that of colloidal materials. The changes in the properties, such as gelation ability, dispersibility, and emulsification ability, of the resultant bulk materials containing these colloidal materials or those of the solid material are also covered. In addition, design criteria for high sensitivity, quick responsiveness, and high reversibility are presented. In each author’s original system, the correlations between molecular-level responses and bulk functional responses are described as well. This book serves as an excellent guide to designing and fabricating novel, functional, eco-friendly stimuli-responsive interfaces and related materials.

This Report presents information on the current state of knowledge of the origins, occurrence, nature and effects of sewer solids for use by engineers, scientists, administrators and water quality planners for the planning, design and operation of sewerage systems. The report addresses both sewer maintenance requirements and environmental protection issues. Increasing environmental standards, coupled with public expectations, have led to stringent water quality standards. In response to this, it has been necessary to develop new methodologies and computer based analytical techniques to model and understand the performance of all aspects of waste water systems. Fundamental to these techniques is the understanding of the way in which sewer solids contribute to the poor performance of wastewater systems and consequential environmental damage. The information presented in this Report about the origins, nature, movement, hydraulic and polluting effects of solids in sewers has enabled strategies and rules to be developed for the management of sewerage systems to minimise the deleterious effects of these solids and associated pollutants.

This book reports on cutting-edge research and technical achievements in the field of hydraulic drives. The chapters, selected from contributions presented at the International Scientific-Technical Conference on Hydraulic and Pneumatic Drives and Controls, NSHP 2020, held on October 21-23, 2020, in Trzebieszowice, Poland, cover a wide range of topics such as theoretical advances in fluid technology, work machines in mining, construction, marine and manufacturing industry, and practical issues relating to the application and operation of hydraulic drives. Further topics include: safety and environmental issues associated with the use of machines with hydraulic drive, and new materials in design of hydraulic components. A special emphasis is given to new solutions for hydraulic components and systems as well as to the identification of phenomena and processes occurring during the operation of hydraulic and pneumatic systems.
