This books studies syntax of NPIs and their interaction with sentential negatives in Hindi. It outlines the clause structure of Hindi and locates the syntactic position of sentential negatives as well as constituent negatives within the structure. It is argued that sentential negative in Hindi negation marker heads its own maximal projection, NegP, which is immediately dominated by TP. In addition to locating the position of negation markers in the clause structure, it outlines the distribution of negative polarity items (NPIs) in Hindi and the structural constraints on their licensing by sentential negative. The book argues that an NPI in Hindi is licensed overtly in the course of derivation by a c-commanding negative marker. The bulk of the evidence presented in this book argues against previous theoretical accounts that claim that NPI licensing involves covert syntactic operations such as LF movement or reconstruction. With respect to the classification of NPIs, this book also shows the existence of two different types of NPIs in Hindi; namely, strong NPIs and weak NPIs. Strong NPIs require a clause mate c-commanding negative licensor, whereas weak NPIs are quantifiers and are similar to free choice 'any' in English that are interpreted as NPIs in the presence of a c-commanding negative licensor.

First Published in 2006. This volume introduces and provides a semantic analysis of Discourse Adjectives, a natural class of adjectives that the author argues includes apparent, clear, evident, and obvious among its prototypical members. With a main claim that Discourse Adjectives do not provide information about the facts of the world. Rather, they are used by interlocutors to negotiate the status of propositions in a discourse.

Although sintering is an essential process in the manufacture of ceramics and certain metals, as well as several other industrial operations, until now, no single book has treated both the background theory and the practical application of this complex and often delicate procedure. In Sintering Theory and Practice, leading researcher and materials engineer Randall M. German presents a comprehensive treatment of this subject that will be of great use to manufacturers and scientists alike.

This practical guide to sintering considers the fact that while the bonding process improves strength and other engineering properties of the compacted material, inappropriate methods of control may lead to cracking, distortion, and other defects. It provides a working knowledge of sintering, and shows how to avoid problems while accounting for variables such as particle size, maximum temperature, time at that temperature, and other problems that may cause changes in processing.

The book describes the fundamental atomic events that govern the transformation from particles to solid, covers all forms of the sintering process, and provides a summary of many actual production cycles. Building from the ground up, it begins with definitions and progresses to measurement techniques, easing the transition, especially for students, into advanced topics such as single-phase solid-state sintering, microstructure changes, the complications of mixed particles, and pressure-assisted sintering. German draws on some six thousand references to provide a coherent and lucid treatment of the subject, making scientific principles and practical applications accessible to both students and professionals. In the process, he also points out and avoids the pitfalls found in various competing theories, concepts, and mathematical disputes within the field.

An original, comprehensive survey on the complex relationship between plastics and the environment

Plastics offer a variety of environmental benefits. However, their production, applications, and disposal present many environmental concerns. Plastics and the Environment provides state-of-the-art technical and research information on the complex relationship between the plastic and polymer industry and the environment, focusing on the sustainability, environmental impact, and cost—benefit tradeoffs associated with different technologies.

Bringing together the field’s leading researchers, Anthony Andrady’s innovative collection not only covers how plastics affect the environment, but also how environmental factors affect plastics. The relative benefits of recycling, resource recovery, and energy recovery are also discussed in detail. The first of the book’s four sections represents a basic introduction to the key subject matter of plastics and the environment; the second explores several pertinent applications of plastics with environmental implications–packaging, paints and coatings, textiles, and agricultural film use. The third section discusses the behavior of plastics in some of the environments in which they are typically used, such as the outdoors, in biotic environments, or in fires. The final section consists of chapters on recycling and thermal treatment of plastics waste. Chapters include:

• Commodity Polymers
• Plastics in Transportation
• Biodegradation of Common Polymers
• Thermal Treatment of Polymer Waste
• Incineration of Plastics

The contributors also focus on the effectiveness of recent technologies in mitigating environmental impacts, particularly those for managing plastics in the solid waste stream. Plastic and design engineers, polymer chemists, material scientists, and ecologists will find Plastics and the Environment to be a vital resource to this critical industry.

Commercially successful fully synthetic polymeric materials were pro duced in the early years of this century, the first example being Bakelite. This was made from phenol and formaldehyde by Leo Bakeland in 1909. Before the end of the 1920s, a large number of other synthetic polymers had been created, including polyvinyl chloride and urea-formaldehyde. Today, there are literally hundreds of synthetic polymers commercially available with ranges of properties making them suitable for applications in many industrial sectors, including the electrical and electronics industries. In many instances the driving force behind the development of new materials actually came from the electronics industry, and today's advanced electronics would be inconceivable without these materials. For many years polymers have been widely used in all sectors of the electronics industry. From the early days of the semiconductor industry to the current state of the art, polymers have provided the enabling technologies that have fuelled the inexorable and rapid development of advanced electronic and optoelectronic devices."

Polymers have undoubtedly changed the world through many products that improve our lives. However, additives used to modify the overall characteristics of these materials may not be fully disclosed or understood. These additives may present possible environmental and health hazards. It is important to monitor consumer products for these compounds using high-quality reference materials and dependable analytical techniques. The Handbook for the Chemical Analysis of Plastic and Polymer Additives, Second Edition provides the necessary tools for chemists to obtain a more complete listing of additives present in a particular polymeric matrix. It is designed to serve as a valuable source for those monitoring a polymer/plastic material for regulatory or internal compliance. It also helps analysts to correctly identify the complex nature of the materials that have been added to the polymer/plastic. With 50 additional compounds, this second edition nearly doubles the number of additives in several categories, including processing aids, antistatic compounds, mould release products, and blowing agents. It includes a listing that can be cross-referenced by trade name, chemical name, CAS number, and even key mass unit ions from the GC/MS run. Addressing additives from an analytical viewpoint, this comprehensive handbook helps readers identify the additives in plastics. This information can be used to assess compliance with regulations issued by the FDA, US EPA, EU, and other agencies.
