Book Description
The premixing method involves adding a small amount of cement to the soil used in reclamation. The cement reacts with the water in the soil to produce a stronger, non-liquifying material for construction. The premixing method can therefore reduce construction time, as the counter-measure work is carried out simultaneously with the reclamation process. In addition, the resultant material has enhanced bearing capacity, and there is a reduction in earth pressure due to the increase in cohesion. This book examines the premixing method in detail and is essential reading for coastal engineers, hydrologists, or construction engineers working in soft soil areas.

Book Description
The Deep Mixing Method (DMM), a deep in-situ soil stabilization technique using cement and/or lime as a stabilizing agent, was developed in Japan and in the Nordic countries independently in the 1970s. Numerous research efforts have been made in these areas investigating properties of treated soil, behavior of DMM improved ground under static and dynamic conditions, design methods, and execution techniques. Due to its wide applicability and high improvement effect, the method has become increasingly popular in many countries in Europe, Asia and in the USA. In the past three to four decades, traditional mechanical mixing has been improved to meet changing needs. New types of the technology have also been developed in the last 10 years; e.g. the high pressure injection mixing method and the method that combines mechanical mixing and high pressure injection mixing technologies. The design procedures for the DM methods were standardized across several organizations in Japan and revised several times. Information on these rapid developments will benefit those researchers and practitioners who are involved in ground improvement throughout the world. The book presents the state of the art in Deep Mixing methods, and covers recent technologies, research activities and know-how in machinery, design, construction technology and quality control and assurance. The Deep Mixing Method is a useful reference tool for engineers and researchers involved in DMM technology everywhere, regardless of local soil conditions and variety in applications.

Book Description
Systematic treatment of difficult ground as a separate paper in undergraduate and postgraduate courses is gaining ground in Indian universities. Earlier, these topics were taught under a variety of subjects like Advanced Geotechnical Engineering, Retaining Structures, Dams, Pavement Designs, Application of Geosynthetics, Application of Soil Mechanics, and so on. However, field requirement and advances in the technology make a strong case for a focused treatment of the subject which this book provides. A full-fledged paper in ground improvement techniques concentrates on the topics of soil stabilization, compaction, preloading, vertical drains, geosynthetics, in-situ reinforcements and modelling of soil reinforcement. The book provides an overview of the basic concepts of ground modifications to difficult soils in a logical and illustrative way. It teaches how to apply alternative solutions to difficult foundation problems and evaluate their effectiveness before and after construction. The text is supported by a large number of examples, review and multiple choice questions, as well as practical problems. The book is intended to serve as a textbook for undergraduate and postgraduate students of Geotechnical, Transportation, Hydraulic and Environmental Engineering, and a reference work for practising civil engineers. Salient features 1. A well researched textbook on ground improvement techniques 2. Conforms to the syllabi of all Indian universities where the subject is taught 3. Written by an expert on the subject with a decade of teaching experience

Book Description
The pneumatic flow mixing method was developed to stabilize dredged soil and surplus soil for promoting their beneficial use in 1999. The pneumatic flow mixing method is a new type of the ex-situ cement stabilization techniques, in which dredged soil and surplus soil is mixed with a relatively small amount of chemical binder without any mixing paddles and blades in a pipeline. When a relatively large amount of compressed air is injected into the pipeline, soil can be separated into small blocks. When binder is injected into the pipeline, the soil block and binder are thoroughly mixed by means of turbulent flow generated in the soil block during transporting. As this method has many benefits − rapid and large scale execution can be conducted with low cost − it has been applied to many land reclamation projects, backfilling behind earth retaining wall projects and shallow stabilization projects using dredged soils and surplus soils. The Pneumatic Flow Mixing Method is a useful reference tool for engineers and researchers involved in admixture stabilization technology everywhere, regardless of local soil conditions and a variety in applications.

Book Description
Fibrin plays a prominent role in wound healing. It has a hemostatic effect, induces cellular response to wound damage, ' and, by forming strands to build a matrix, assists in neovascularization and fibroblast proliferation. The concept of using clotting substances from human blood for wound manage ment and to achieve hemostasis in bleeding parenchymatous organs can be traced to 1909, when Bergel [1] reported on the hemostatic effect of fibrin powder. In 1915, Grey [3] employed fibrin to control bleeding in neurosurgical operations of the brain. A year later, Harvey [4] used fibrin patches to stop bleeding from parenchy matous organs in general surgery. It took more than two decades for this ingenious idea to be rediscovered. In 1940, Young and Medawar [8] reported on experimental nerve anastomosis by sealing. Similarly, Tarlov and Benjamin [7] reunited nerves with plasma clots in 1943. Tarlov improved the results obtained with clot anastomosing of nerves by avoiding tension at the nerve stumps. In 1944, Cronkite et al. [2] reported on an initial series of eight cases in which fibrinogen and thrombin had been used successfully for anchoring skin grafts.
