Water-dependent habitats are extremely diverse in terms of their nature (e.g., drylands, wetlands, streams/rivers and ponds/lakes), geography (poles to equator, low to high latitude) and many support communities and species of high conservation value, some of which are under threat from extinction. As pressure is increasing on water-dependent habitats due to global change and ever growing anthropogenic impacts, it is clear that balancing the water needs of people against those of ecosystems (terrestrial and aquatic) is, and will increasingly become, a premier environmental issue. This crucial, often precarious ‘balancing act’ involves some highly complex issues and, thus, it has compelled recent workers to identify the need, not only for new integrative science (between traditional fi elds of hydrology–ecology) and analytical approaches, but for truly interdisciplinary research. In this context, it has been argued that the ‘new’ discipline(s) of hydroecology/ecohydrology has the potential not only to unlock elements of this complexity, but also to provide a foundation for the sustainable management of water resources.

The research projects carried out at the Railway Engineering Group of Delft University of Technology have played a central role. The theory of railway track and vehicle track interaction has been substantially enhanced and much more attention has been given to dynamics.
Undoubtedly one of the most important extensions was the part on slab track structures. But also track management systems have been given much more attention. Numerical optimization and testing, as well as acceptance are new chapters.
This book should prove to be a useful contribution to the training and instruction of permanent way engineers. The concept of integrated quality control presented will provide managers responsible for track maintenance and renewal with effective cost-saving tools.

Author: N. S. V. Kameswara Rao | Size: 42 MB | Format:PDF | Publisher: John Wiley & Sons | Year: Jan 2011 | pages: 544 | ISBN: 978-0-470-82534-1
In Foundation Design: Theory and Practice, Professor N. S. V. Kameswara Rao covers the key aspects of the subject, including principles of testing, interpretation, analysis, soil-structure interaction modeling, construction guidelines, and applications to rational design. Rao presents a wide array of numerical methods used in analyses so that readers can employ and adapt them on their own. Throughout the book the emphasis is on practical application, training readers in actual design procedures using the latest codes and standards in use throughout the world.
* Presents updated design procedures in light of revised codes and standards, covering:
o American Concrete Institute (ACI) codes
o Eurocode 7
o Other British Standard-based codes including Indian codes
* Provides background materials for easy understanding of the topics, such as:
o Code provisions for reinforced concrete
o Pile design and construction
o Machine foundations and construction practices
o Tests for obtaining the design parameters
* Features subjects not covered in other foundation design texts:
o Soil-structure interaction approaches using analytical, numerical, and finite element methods
o Analysis and design of circular and annular foundations
o Analysis and design of piles and groups subjected to general loads and movements
* Contains worked out examples to illustrate the analysis and design
* Provides several problems for practice at the end of each chapter
* Lecture materials for instructors available on the book's companion website
Foundation Design is designed for graduate students in civil engineering and geotechnical engineering. The book is also ideal for advanced undergraduate students, contractors, builders, developers, heavy machine manufacturers, and power plant engineers. Students in mechanical engineering will find the chapter on machine foundations helpful for structural engineering applications.

This code of practice gives recommendations for cement-based external renderings on all common types of background. It includes renderings on both new and old backgrounds and the maintenance and
repair of existing work. Renderings for liquid retaining structures such as
tanks and manholes and renderings applied as a background for any form of cladding are not included.
NOTE 1 For renderings to receive external tiling and mosaics, see BS 5385-2.
NOTE 2 The titles of the publications referred to in this standard are listed on page 36.

This British Standard specifies requirements for the transport, laying and compaction of those asphalt mixtures conforming to BS EN 13108-1, BS EN 13108-4 and BS EN 13108-5, described in PD 6691, from the time that they leave the mixing plant until they are placed on the road ready to receive a superimposed layer or traffic. It also includes requirements for preliminary work at the laying site needed to ensure that the substrate is fit to receive the asphalt and for the application of tack coats and bond coats. While this standard does not include explicit requirements for asphalt materials covered in other parts of BS EN 13108 or other proprietary asphalt mixtures, the general requirements of this standard may be applied to those mixtures, in addition to special requirements for particular mixtures as laid down in individual quality plans and/or method statements.
NOTE 1 The term “asphalt” used in this standard is the generic term used to describe the wide range of mixtures of aggregate and bituminous binder individually known as asphalt concrete, coated macadam, hot
rolled asphalt, stone mastic asphalt (SMA), porous asphalt or mastic asphalt and other proprietary materials which are available for use in constructing and maintaining roads and other paved areas that are on the market in the UK. Protocols for the initial type testing of asphalt materials in accordance with BS EN 13108-20 Type testing are included in Annex C, Annex D, Annex E, Annex F and Annex G.
NOTE 2 BS EN 13108-20 Type testing details the way in which the conformity of a mix composition to the requirements of the specification is to be determined. This is similar to a mix design validation or job mix trial. BS EN 13108-20 offers some choice in the way in which specimens are to be prepared for the purposes of initial type testing. Since the results determined will depend on the method of specimen preparation, a set of
protocols showing the recommended UK selection of such procedures, linked to the recommended specification levels and classes, is included in this standard.
In the case of hot rolled asphalt (HRA), requirements are specified for providing a rough-textured surface on the surface course for skid-resistance. This standard does not include requirements for asphalt incorporating bitumen emulsion binders.
