Book Description
The report "Analyses of quaternary ammonium compounds in a Nordic cooperation on screening" describes the findings of a Nordic environmental study. The quaternary ammoniums included are compounds which are used in large volumes in a variety of industrial, health sector and domestic products. The quaternary ammoniums are used to provide antistatic, antibacterial, emulating and other properties in a range of formulations like hair conditioners, cosmetics, in fabric softeners and in cleansing and disinfecting products. Some quaternary ammoniums are poorly degraded and some are highly toxic to aquatic organisms. The samples analysed were taken mainly near assumed hot-spot areas as in sewage lines and in receiving waters, but also in background areas far from anthropogenic sources. Samples include water, sludge, sediment and fish.

Book Description
Phase transfer catalysis is a sophisticated chemical technique which can be used to perform a variety of chemical reactions under mild conditions and with improved control. Since the concept was developed, both the theoretical and practical synthetic applications have seen considerable development, to the point where the technique can be applied to many areas of chemistry. Thus, phase transfer methods are now utilized in many applications, from research chemistry to full-scale production, where the benefits of faster, cleaner and more selective reactions are required. In this new book, the editors have brought together a range of contributors, each of whom is working at the forefront of the technology, to provide a clear, concise and ahtoritative review of this important area of chemistry. Industrial and academic chemists working on the synthesis, scale-up, production or analysis of a wide range of chemical products will find this book an essential reference on phase transfer technology.

Book Description
Nanobiomaterials in Clinical Dentistry, Second Edition shows how a variety of nanomaterials are being used to solve problems in clinical dentistry. New nanomaterials are leading to a range of emerging dental treatments that utilize more biomimetic materials that more closely duplicate natural tooth structure (or bone, in the case of implants). The book's chapters discuss the advantages and challenges of using nanomaterials and include case studies to illustrate how a variety of materials are best used in research and practice. Contains information from an interdisciplinary, international group of scientists and practitioners in the fields of nanomaterials, dental implants, medical devices and clinical practice Presents a comprehensive reference on the subject that covers material fabrication and the use of materials for all major diagnostic and therapeutic dental applications--repair, restoration, regeneration, implants and prevention Complements the editors' previous book on nanotechnology applications for dentistry

Book Description
Addressing the widespread need for a practical guide to imaging mass spectrometry (IMS), this book presents the protocols of IMS technology. As that technology expands, research groups around the world continue its development. Pharmaceutical companies are using IMS for drug analyses to study pharmacokinetics and medical properties of drugs. Drug research and disease-related biomarker screening are experiencing greater use of this technology, with a concurrent increase in the number of researchers in academia and industry interested in wider applications of IMS. Intended for beginners or those with limited experience with IMS technology, this book provides practical details and instructions needed for immediate know-how, including the preparation of animal tissue samples, the application of a matrix, instrumental operations, and data analysis, among others. By describing the foundations of IMS, this volume contributes to the ongoing development of the field and to progress in human health.

Book Description
This Monograph provides the general respiratory physician with a working reference based on the latest literature and expert opinion. The initial chapter provides a contemporaneous global perspective of the epidemiology of occupational and environmental lung diseases in an ever-evolving landscape. The book then goes on to consider specific occupational lung diseases. Each chapters has a clear clinical focus and considers: key questions to ask in the history; appropriate investigations to undertake; differential diagnoses; and management. Controversies or diagnostic conundrums encountered in the clinic are also considered, and further chapters are more broadly centred on the non-workplace environment; specifically, the respiratory symptoms and diseases associated with both the outdoor and indoor environments.
