A major goal of materials science is to create new engineering materials and optimize their cost and performance. Understanding how adjacent materials behave at their borders is an essential part of this process. Grain boundaries are the longest-known crystal defects, but although they were discovered in the mid-eighteenth century, until quite recently, we did not understand them very well. Even now, scientists are still searching for the best ways to comprehensively characterize a material s microstructure and accurately predict its evolution and behavior.

Ritual Communication examines how people create and express meaning through verbal and non-verbal ritual. Ritual communication extends beyond collective religious expression. It is an intrinsic part of everyday interactions, ceremonies, theatrical performances, shamanic chants, political demonstrations and rites of passage.

Despite being largely formulaic and repetitive, ritual communication is a highly participative and self-oriented process. The ritual is shaped by time, space and the individual body as well as by language ideologies, local aesthetics, contexts of use, and...

The Raspberry Pi has dominated the maker scene for many years. Freely accessible I/O pins have made it one of the most popular processor boards of all time. However, the classic Raspberry Pi has no analog inputs. Direct measurement of analog values is therefore not possible. Consequently, photodiodes, NTCs, Hall sensors, etc. cannot be read directly. In addition, the pins are connected directly to the exposed contacts, i.e. without a driver or protection circuit. This can quickly destroy the central controller and thus the entire Raspberry Pi.

These problems can be elegantly solved...

This book examines the relationship between the public and the BBC in terms of public use of the BBC and their attitudes towards it. These audience research measures are being used as metrics to assess the value of the BBC to the UK public. Some of the attitudinal measures address perceptions of the BBC’s outputs and some examine public views about the way the BBC is funded and managed.

The book has been written at a time when the BBC reached its centenary and also the mid-point of its latest Royal Charter period. At the time of writing, the government had begun a mid-term review...
