Development and In-vitro Dissolution Test of Pilocarpine PVA : Hydrogel Lenses

Due to high water content of hydrogel (wetting) and due to extended drug release comparing to ophthalmic solution and higher transparency comparing to ophthalmic ointment, soft contact lenses were found to elongate contact time with the eye and use it for long time without causing hypoxia or needing multiple dosing per a day. The objective of the study was to design, fabricate, and investigate the effectiveness of PVA hydrogel with DMSO soft contact lens in releasing the model drug, pilocarpine.

Current techniques and materials in dentistry

Dental implants are one of the most interesting dental treatments. PEEK (polyetheretherketone) has recently been reported as a further innovation in polymer implant materials, although it has not yet met the requirements to be a biomechanical requirement. In the placement of mini-screws used in orthodontic treatments, micro-cracks caused by overtorquing in thick and hard bone, and the consequent heat production, can reduce the success rate. Computer-aided design/computer-aided manufacturing (CAD/CAM) techniques are becoming increasingly popular. Since complete dentures can be produced using an additive (3D printing) or subtractive (milling) process, CAD/CAM techniques for denture fabrication have many clinical and laboratory advantages.

Construction Materials Manual

Until now, the few existing systematic texts on construction materials have primarily been directed at building engineers. An overview for architects, which also considers the importance of construction materials in the sensory perception of architecture—including tactile qualities, smell, color, and surface structure—has not been available. aims equally at the questions and perspectives of architects and building engineers, it will bring together all of the above-mentioned viewpoints. It addresses fundamental questions of sustainability, including life-span, environmental impact, and material cycles, while also presenting material innovations. All of the principal conventional and innovative construction materials are comprehensively documented, with attention to their production, manufacture, fabrication, treatment, surfaces, connections, and characteristics.

Coastal Fluxes in the Anthropocene : The Land-Ocean Interactions in the Coastal Zone Project of the International Geosphere-Biosphere Programme

In global coastal zones, the major fabric of goods and services for human welfare as well as global changes are extraordinarily visible. They are shaped by natural Earth systems processes on a planetary scale, which are reflected in a continuously adapting coastal environment. Now, in the "Anthropocene", human society is a greater catalyst for change - impacting and modifying coastal processes. This book synthesizes knowledge on coastal and riverine material fluxes, biogeochemical processes and indications of change, and the human influence, before looking at future research and management needs. It is a milestone rather than a destination on the journey which continues under the new International Geosphere-Biosphere Programme (IGBP), the International Human Dimensions Programme on Global Environmental Change (IHDP) and the LOICZ II (Land-Ocean Interactions in the Coastal Zone) Project.

Also, the desired properties of these materials are discussed and the relevance of the chemical, physical, and mechanical properties is elucidated. Methods for the characterization and classification, as well as clinical studies are reviewed here. In particular, materials for dental crowns, implants, toothpaste compositions, mouth rinses, as well as materials for toothbrushes and dental floss are discussed. For example, in toothpaste compositions, several classes of materials an chemcials are incorporated, such as abrasives, detergents, humectants, thickeners, sweeteners, coloring agents, bad breath reduction agents, flavoring agents, tartar control agents, and others. These chemicals, together with their structures, are detailed in the text.
