Описание: These proceedings document the various papers delivered and partially presented at the International Conference "From experimental evidence towards numerical modeling of unsaturated soils," which was held in Weimar (Germany) during 18-19 September 2003. The conference was organized under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) and the National German G- technical Society (DGGT). The need to understand the behavior of unsaturated soils is becoming exclusively - sential for the geotechnical engineers and designers. In the last three decades many - searchers have made significant contribution to the understanding of the unsaturated soil mechanics. Nevertheless, application of the subject to variety of new problems still - quires our attention. This International conference is a mere attempt to unite researchers and engineers in geotechnical engineering and to discuss about the problems associated with the unsaturated soils. Doing so the objectives of these lecture notes are as follows: - to promote unsaturated soil mechanics for practical application, - to exchange experiences in experimental unsaturated soil mechanics and numerical modeling, - to discuss application of unsaturated soil mechanics to variety of problems. In other words, we could also name these two volumes as "From theory to daily pr- tice." I would like to extend my deep sense of appreciation as the editor and the Head of the organizing committee, to many persons who have contributed either directly or indirectly to organize the International conference and to finalize these proceedings.

Описание: These proceedings are a continuation of the series of International Conferences in Germany entitled "Mechanics of Unsaturated Soils." The primary objective is to discuss and understand unsaturated soil behaviour such that engineered activities are made better with times in terms of judgement and quality. We all realise by now that in addition to the knowledge on the classical concepts, it becomes an enormous challenging task to adapt convincing new concepts and present them in such a way that it could be used in engineering practices. These proceedings would have been not possible without financial support by the German Research Foundation (DFG). We gratefully acknowledge the support of ISSMGE, especially TC6 "Unsaturated Soils".

Описание: Polymers that can degrade into biologically compatible components under physiologic conditions are advantageous for the preparation of drug delivery systems (DDS). The use of biodegradable polymers precludes the need for retrieval at the conclusion of the dosing regimen, thereby avoiding the potential complications associated with the use of non-degradable systems. Homopolymers and copolymers, obtained from glycolide, lactide and caprolactone and trimethylene carbonate (TMC), are the most commonly considered drug delivery vehicles. However, there are still few implantable drug delivery systems obtained from biodegradable polymers. Attachment of drugs to high molecular weight polymers can significantly improve both tumor targeting and therapeutic efficacy due to the enhanced permeability and retention effect observed in tumour tissue. However, the commercial availability of well-defined water-soluble polymeric systems with narrow polydispersities that are biocompatible, nontoxic, and nonimmunogenic is rather limited. Even with the progress of novel materials, polyesters still endure at the controls of drug delivery technologies. The book provides comprehensive information of polyester drug delivery systems that covers a wide-ranging of materials design, manufacturing techniques, and applications. Polyglycolide (PGA) was one of the first biodegradable synthetic polymers investigated for biomedical applications and was synthesised for the first time in 1954. In the beginning, it was not considered for biomedical applications because of its thermal and hydrolytic instability. However, the ability to degrade inside the human body became a great advantage.

Crazing Technology for Polyester Fibers reviews PET fibers crazing in surface-active liquids and the use of the crazing mechanism for fiber modification by functional additives. The first chapter reviews existing literature, and subsequent chapters present the research of the authors, with an emphasis on how these techniques can be used to create textiles for a wide variety of purposes.
With two highly regarded and very experienced authors bringing together the latest information on polyester crazing technology, this book is essential reading for scientific researchers, engineers, and R&D professionals working on the development of fibers for improving the properties of textiles.

Описание: In the opening chapter of Polyester: Synthesis, Types and Applications, the authors provide the synthesis, structure, properties and applications of thermoplastic copolyester elastomers. Thermoplastic copolyester elastomers belong to the class of thermoplastic elastomers which combine mechanical properties of chemically crosslinked elastomers with those of thermoplastics. Due to their high performance, an extensive section on mechanical, thermal and chemical properties is presented. The recent development of materials such as nanocomposites and blends, as well as biodegradable thermoplastic copolyester elastomers, are also addressed. Next, the book chapter gives an overview on the natural and synthetic polyesters that are used in different medical fields for bonding, as closures, for separation, scaffolds, capsulation, as drug deliverers, and for prostheses. The authors summarize the historical background of the polyesters, explain the meaning of the biodegradation, and shortly characterize the most interesting polyesters from the point of view of their synthesis and medical application possibilities. The authors examine classical melt polycondensation, an old synthetic method which is difficult to handle and high-energy consuming. The polyesters obtained lack pendant functionalities, which restricts applicability in a range of practices. The new trends for overcoming this drawback with biobased polyesters are highlighted. In the concluding study, cost-effective nanostructured polyester was engineered infusing carbon nanofibers. The sonication dispersion technique was employed to infuse 0.1-0.4 wt% CNF into polyester matrix to enhance mechanical properties of resulting nanocomposites. The effect of dispersion conditions was investigated as a function of CNF content and the sonication time.
