The Organization Of Transport

RRP $268.99

Over the past ten years, the study of mobility has demonstrated groundbreaking approaches and new research patterns. These investigations criticize the concept of mobility itself, suggesting the need to merge transport and communication research, and to approach the topic with novel instruments and new methodologies. Following the debates on the role of users in shaping transport technology, new mobility research includes debates from sociology, planning, economy, geography, history, and anthropology.

This edited volume examines how users, policy-makers, and industrial managers have organized and continue to organize mobility, with a particularly attention to Europe, North America, and Asia. Taking a long-term and comparative perspective, the volume brings together thirteen chapters from the fields of urban studies, history, cultural studies, and geography. Covering a variety of countries and regions, these chapters investigate how various actors have shaped transport systems, creating models of mobility that differ along a number of dimensions, including public vs. private ownership and operation as well as individual vs. collective forms of transportation. The contributions also examine the extent to which initial models have created path dependencies in terms of technology, physical infrastructure, urban development, and cultural and behavioral preferences that limit subsequent choices.

Understanding Sport As A Religious Phenomenon

RRP $316.99

Understanding Sport as a Religious Phenomenon introduces students to the rapidly growing field of religion and sport. Including global case studies, discussion questions, suggestions for further reading, 20 illustrations, and a glossary, it is ideal for teaching courses on sport and spirituality, religion and sport, and religion and popular culture.

Readers are introduced to a range of theoretical and methodological approaches used in the study of religion - including sociology, philosophy, psychology, and anthropology - and how they can be used to query a diverse range of case studies from the world of sport. Topics include the formation of powerful communities among fans and the religious experience of the fan, myth, symbols and rituals and the sacrality of sport, and sport and secularization. Case studies are taken from around the world and include the Olympics past and future, football in the UK, the All Blacks and New Zealand national identity, college football in the American South, and basketball.

Ideal for classroom use, Understanding Sport as a Religious Phenomenon illuminates the nature of religion through sports phenomena and is a much-needed contribution to the field of religion and popular culture.


Topology Control In Wireless Sensor Networks

RRP $276.99

The eld of wireless sensor networks continues to evolve and grow in both practical and research domains. More and more wireless sensor networks are being used to gather information in real life applications. It is common to see how this technology is being applied in irrigation systems, intelligent buildings, bridges, security mec- nisms,militaryoperations,transportation-relatedapplications,etc.Atthesametime, new developments in hardware, software, and communication technologies are - panding these possibilities. As in any other technology, research brings new dev- opments and re nements and continuous improvements of current approaches that push the technology even further. Looking toward the future, the technology seems even more promising in two directions. First, a few years from now more powerful wireless sensor devices will be available, and wireless sensor networks will have applicability in an endless number of scenarios, as they will be able to handle traf c loads not possible today, make more computations, store more data, and live longer because of better energy sources. Second,a few years from now, the opposite scenario might also be possible. The availability of very constrained, nanotechnology-made wireless sensor devices will bring a whole new world of applications, as they will be able to operate in - vironments and places unimaginable today. These two scenarios, at the same time, will both bring new research challenges that are always welcome to researchers.


Slurry Transport Using Centrifugal Pumps

RRP $35.00

1,1 Applications of Slurry Transport Vast tonnages are pumped every year in the form of solid-liquid mixtures, known as slurries. The application which involves the largest quantities is the dredging industry, continually maintaining navigation in harbours and rivers, altering coastlines and winning material for landfill and construction purposes. As a single dredge may be required to maintain a throughput of 7000 tonnes of slurry per hour or more, very large centrifugal pumps are used. Figures 1-1 and 1-2 show, respectively, an exterior view of this type of pump, and a view of a large dredge-pump impeller (Addie & Helmley, 1989). The manufacture of fertiliser is another process involving massive slur- transport operations. Li Florida, phosphate matrix is recovered by huge draglines in open-pit mining operations. It is then slurried, and pumped to the wash plants through pipelines with a typical length of about 10 kilometres. Each year some 34 million tonnes of matrix are transported in this manner. This industry employs centrifugal pumps that are generally smaller than those used in large dredges, but impeller diameters up to 1. 4 m are common, and drive capacity is often in excess of 1000 kW. The transport distance is typically longer than for dredging applications, and Chapter 1 Figure LI. Testing a dredge pump at the GIW Hydraulic Laboratory Figure 1. 2. Impeller for large dredge pump 1. Introduction 3 hence a series of pumping stations is often used. Figure 1-3 shows a boost- pump installation in a phosphate pipeline.
