Oculoplastics and Orbit
Considerable progress has been made in various fields of oculoplastic surgery, e.g. the development of endoscopic transcanalicular as well as endonasal minimal invasive techniques in lacrimal surgery, the use of muscle pedunculated scleral flaps to improve implant motility without pegging. This extraordinary volume enhances your understanding of Graves’ ophthalmopathy and helps you to define situations suitable for radiotherapy and more differentiated surgical strategies such as orbital fat resection, balance bony decompression and lid lengthening procedures. It exemplifies progress in aesthetic surgery such as endoscopic brow lift and soft techniques for mid-face rejuvenation and discusses general risks of infectious disease transmission using allografts as well as current concepts in the management of conjunctival neoplasms.

Monitors of Organic Chemicals in the Environment : Semipermeable Membrane Devices
Modern, industrialized societies depend on a wide range of chemical substances such as fuels, plastics, biocides, pharmaceuticals and detergents for maintaining the high quality lifestyle to which we aspire. The challenge is to ensure that while we enjoy the benetsof thes esubstances,theirinevitablereleaseintoourbiosphere does not result in unwanted human and ecosystem exposures, and the risk of - verse effects. One response to this challenge has been the extensive effort to detect and analyze or monitor a multitude of chemicals in a variety of environmental media, especially toxic organic compounds in air, water, soils and biota. An extensive literature on these traditional techniques has evolved over the years.
Microplastic in the Environment : Pattern and Process
This book examines global plastic pollution, an issue that has become a critical societal challenge with implications for environmental and public health. This volume provides a comprehensive, holistic analysis on the plastic cycle and its subsequent effects on biota, food security, and human exposure. Importantly, global environmental change and its associated, systems-level processes, including atmospheric deposition, ecosystem complexity, UV exposure, wind patterns, water stratification, ocean circulation, etc., are all important direct and indirect factors governing the fate, transport and biotic and abiotic processing of plastic particles across ecosystem types.
High Performance Tensegrity-Inspired Metamaterials and Structures
New metamaterials, smart materials and structures, and adaptive systems with adjustable behaviour or which use high performance or 'extremal' materials can be applied to bigger structural systems, such as cellular tensegrity lattices with extremal mechanical properties. Numerical analyses justify tensegrities and discrete and continuum models offer two main approaches to the analysis of tensegrity-based mechanical metamaterials and lattices. Two examples of 2D and 3D tensegrity modules and lattices, and potential applications in civil engineering are presented.
Handbook of Biodegradable Materials
Discusses the recent advances in biodegradation technologies and highlights emerging sustainable materials, including environmentally friendly nano-based materials for replacing plastics. It is useful to scientists, engineers, biologists, medical doctors and provides alternative eco-friendly materials to replace the currently used ones with harmful impact on the environment and life. The chapters present different types of alternative materials in diverse areas, such as food packaging materials, materials for construction and agricultural materials. The principles and types of biodegration technologies are described in depth.
Freshwater Microplastics : Emerging Environmental Contaminants?
Focuses on microscopic plastic debris, also referred to as microplastics, which have been detected in aquatic environments around the globe and have accordingly raised serious concerns. The book explores whether microplastics represent emerging contaminants in freshwater systems, an area that remains underrepresented to date.Given the complexity of the issue, the book covers the current state-of-research on microplastics in rivers and lakes, including analytical aspects, environmental concentrations and sources, modelling approaches, interactions with biota, and ecological implications. To provide a broader perspective, the book also discusses lessons learned from nanomaterials and the implications of plastic debris for regulation, politics, economy, and society. In a research field that is rapidly evolving, it offers a solid overview for environmental chemists, engineers, and toxicologists, as well as water managers and policy-makers.
Encyclopedic Dictionary of Polymers
The editor offers scientists, engineers, academia, and others interested in adhesives, coatings, elastomers, inks, plastics, and textiles a valuable communication tool within this book. In addition, the more recent innovations and biocompatible polymers and adhesives products have necessitated inclusion into any lexicon that addresses polymeric materials. Communication among scientific and engineering personnel has always been of critical importance, andas in any technical field, the terms and descriptions of materials and processes lag the availability of a manual or handbook that would benefit individuals working and studying in scientific and engineering disciplines.
Corrosion and protection of reinforced concrete
This book surveys deterioration of concrete, particularly corrosion of the steel reinforcement, and the various chemical, biological, physical and mechanical causes of deterioration. It outlines condition survey and diagnosis techniques by on-site and laboratory measurements. It sets out mechanical methods of protection and repair, such as patching, inhibitors, coatings, penetrants and structural strengthening as well as cathodic protection and other electrochemical methods.
Materials Handbook : A Concise Desktop Reference
The unique and practical Materials Handbook (second edition) provides quick and easy access to data on the physical and chemical properties of all classes of materials. The second edition has been much expanded to include whole new families of materials while many of the existing families are broadened and refined with new material and up-to-date information. Particular emphasis is placed on the properties of common industrial materials in each class.
Arzneimittel, giftstoffe, kunststoffe, farbstoffe, pestizide = Pharmaceuticals, toxins, plastics, dyes, pesticides
Spells out which methods in which cases produce the most comprehensive results. Beschreibt alle modernen Spektroskopiemethoden in Theorie und Praxis. Behandelt die schnelle und effektive Identifikation von Giftstoffen. Enthält zahlreiche Absorptions- und Massenspektren aus der Zentralkartei der Bayer AG.
Advances in the toxicity of construction and building materials
Presents the potential and toxic effects of building materials on human health, along with tactics on how to minimize exposure. Chapters are divided into four sections covering the toxicity of indoor environments, fire toxicity, radioactive materials, and toxicity from plastics, metals, asbestos, nanoparticles and construction wastes. Key chapters focus on the reduction of chemical emissions in houses with eco-labelled building materials and potential risks posed by indoor pollutants that may include volatile organic compounds (VOC), formaldehyde, semi-volatile organic compounds (SVOC), radon, NOx, asbestos and nanoparticles.
Adhesive Bonding of Aircraft Composite Structures: Non-destructive Testing and Quality Assurance Concepts
This book is under a CC BY 4.0 license. It presents the results of the ComBoNDT European project, which aimed at the development of more secure, time- and cost-saving extended non-destructive inspection tools for carbon fiber reinforced plastics, adhered surfaces and bonded joints. The book reports the optimal use of composite materials to allow weight savings, reduction in fuel consumptions, savings during production and higher cost efficiency for ground operations.
