Essential reading for students and practitioners, this handbook provides an authoritative map of the landscape of forensic science within the criminal justice system of the UK. It examines the identification of individuals and discusses the comparison of drugs, body fluids, and trace evidence. It also explores reconstructing events including those involving bloodstain patterns and fires. The book concludes by discussing the evaluation of scientific evidence and various themes and debates in contemporary forensic science.

First published in 1993.

Cities are increasingly cast as being shaped by globalization and related neoliberal policies. While these diverse literatures have provided needed theoretical advancement to rethink the city in relation to political–economic change, they also run the risk of conceptualizing, studying, and representing cities without sufficient attention to the spatial copresence of multiple actors. The result is that some treatments of the city reproduce a unified story line that conceals human agency, reads as if there is only one trajectory on which all cities are moving, and does not engage in imagining alternative urban futures. In this paper we suggest that there is a continued need to critically examine the spatial narratives mobilized both by researchers as well as by the other actors they encounter. Drawing on the widespread idea that the stories which researchers tell are intimately linked with the conduct of research itself, we advocate a researcher mode of engagement that permits collaborative critique of projects that aim to transform urban space. We report on our experience with two research practices—grounded interviewing, and the public research memo—to provide empirical examples of our perspective.

Superconducting generators (SCG) show the potential to reduce the head mass of large offshore wind turbines. By evaluating the availability and required cooling capacity in the temperatures range around 20 K, a Gifford-McMahon (GM) cryocooler among all the candidates was selected. The cold head of GM cryocooler is supposed to rotate together with the rotating superconducting coil. However, the scroll compressor of the GM cryocooler must stay stationary due to lubricating oil. As a consequence, a rotary helium union (RHU) utilizing Ferrofluidic® sealing technology was successfully developed to transfer helium gas between the rotating cold head and stationary helium compressor at ambient temperatures. It contains a high-pressure and low-pressure helium path with multiple ports, respectively. Besides the helium line, slip rings with optical fiber channels are also integrated into this RHU to transfer current and measurement signals. With promising preliminary test results, the RHU will be installed in a demonstrator of SCG and further performance investigation will be performed. ; This research is primarily supported by the European Union Seventh Framework Programme (FP7/2007-2013) under grant agreement 308793.
