Pronto, chi parla? (Hello, who is it?): telephone as artefacts and communication media in children’s discourses

This book offers a range of perspectives on children's multimodal experiences, providing a ground-breaking account of the ways in which children engage with popular culture, media and digital literacy practices from their earliest years. Many young children have extensive experience of film, television, printed media, computer games, mobile phones and the Internet from birth, yet their reaction to media texts is rarely acknowledged in the national curricula of any country. This seminal text focuses on children from birth to eight years, addressing issues such as: * media and identity construction * media literacy practices in the home * the changing nature of literacy in technologically advanced societies * The place of popular and media texts in children's lives and the use of such texts in the curriculum. By exploring children's engagement with popular culture, media and digital texts in the home, community and early years settings, the contributors look at empirical studies from around the world, and draw out vital new theoretical issues relating to children's emergent techno-literacy practices. With an unmatchable team of international experts evaluating topics from text-messaging to the Teletubbies, this book is a long-overdue, fascinating and illuminating read for policy-makers, educational researchers and practitioners, and crosses over to appeal to those in the linguistics field

A CFD analysis on using a standardized blade in different mechanical draft cooling towers for geothermal power plants

The spare parts standardization without excessively sacrificing energy efficiency may reduce the maintenance costs of components in different geothermal power plants of the same company. This strategy may apply to the blades of the fan used in mechanical draft cooling towers, which usually come in different sizes and are numerous. The case study taken as a reference is a standardized blade, designed for a fan diameter of 8.6 m, used in a 9.2 m diameter fan. The results indicated a decrease in efficiency for the fan with standard blades. Nevertheless, some appendices proved to be effective in limiting the efficiency loss
