Manual of Stroke Models in Rats


Book Description

During the last few years, exciting new insights into mechanisms and treatment of stroke have been obtained from animal experiments. Hence, the use of animal models to induce stroke are of paramount importance as research tools. While a few articles on this topic have been published in select journals, until now there has not been a systematic tech










Advances in Superconductivity VIII


Book Description

Since the discovery of superconductivity with trans1tton temperatures above 77 K, concentrated research activities toward the exploration of practical applica tions of these materials have been carried out. Currently, a remarkable improve ment in superconducting properties has been achieved due to the fine optimization of fabrication processes, and this has attracted industrial interest for future applications. In the case of NdBa Cu 0 materials, a new pinning mecha 2 3 7 nism was found which enhances the critical current under applied magnetic fields. In single crystals of these materials, oxygen control results in an increase in the growth rate. The metalorganic chemical vapor deposition (MOCVD) film quality has been improved by using a new liquid raw material. Simultaneously, real demands from the viewpoint of the market start to be a motivation force, es pecially in electronics application where some products are already being sold. At the same time, interesting physical properlies have been obtained from a new superconducting single crystal which has a layered perovskite structure without copper. In addition, various precision measurement techniques have confirmed the d-wave mechanism and the existence of intrinsicJosephson junctions in single crystals. These new phenomena challenge the existing theoretical models but also open the way for new applications. These significant areas of progress in materials science have led high-Tc super conductivity research into the next phase of activity, while fundamental research continues to be very important. I sincerely hope that this volume will give further impetus to this development.




Composite Materials


Book Description

Composite materials have been well developed to meet the challenges of high-performing material properties targeting engineering and structural applications. The ability of composite materials to absorb stresses and dissipate strain energy is vastly superior to that of other materials such as polymers and ceramics, and thus they offer engineers many mechanical, thermal, chemical and damage-tolerance advantages with limited drawbacks such as brittleness. Composite Materials: Manufacturing, Properties and Applications presents a comprehensive review of current status and future directions, latest technologies and innovative work, challenges and opportunities for composite materials. The chapters present latest advances and comprehensive coverage of material types, design, fabrication, modelling, properties and applications from conventional composite materials to advanced composites such as nanocomposites, self-healing and smart composites. The book targets researchers in the field of advanced composite materials and ceramics, students of materials science and engineering at the postgraduate level, as well as material engineers and scientists working in industrial R& D sectors for composite material manufacturing. - Comprehensive coverage of material types, design, fabrication, modelling, properties and applications from conventional composite materials to advanced composites such as nanocomposites, self-healing and smart composites - Features latest advances in terms of mechanical properties and other material parameters which are essential for designers and engineers in the composite and composite reinforcement manufacturing industry, as well as all those with an academic research interest in the subject - Offers a good platform for end users to refer to the latest technologies and topics fitting into specific applications and specific methods to tackle manufacturing or material processing issues in relation to different types of composite materials

Advances in Cryogenic Engineering Materials


Book Description

The 1995 International Cryogenic Materials Conference (lCMC) was held at the Greater Columbus Convention Center in Columbus, Ohio, in conjunction with the Cryogenic Engineering Conference (CEC) on July 17-21. The interdependent subjects of the two conferences attracted more than eight hundred participants, who came to share the latest advances in low-temperature materials science and technology. They also came for the important by products of the conferences: identification of new research areas, of collaborative research possibilities, and the establishment and renewal of exploration professional relationships. Ted Collings (Ohio State University), as Chairmen of the 1995 ICMC; Ted Hartwig (Texas A&M University), as Program Chairman; and twenty-one other Program Committee members expertly arranged the ICMC technical sessions and related activities. The contributions of the CEC board and its Conference Chairman James B. Peeples of CVI, Inc., were central to the success of the eleventh CEC/ICMC. Jeff Bergen of Lake Shore Cryogenics served as Exhibits Chairman. Local arrangements and conference management were expertly handled under the guidance of Centennial Conferences, Inc. Skillful assistance with editing and preparation ofthese proceedings was provided by Ms. Vicky Bardos ofSynchrony, Inc.
