International Road Tunnel Fire Detection Research Project - Phase II Task 2: Full-Scale Fire Tests in a Laboratory Tunnel

Z. G. Liu, G. P. Crampton, A. Kashef, G. D. Lougheed, E. Gibbs & S. Muradori
This report presents the research works completed in Task 2 of the International Road Tunnel Fire Detection Research Project ? Phase II. The capabilities and limitations of nine fire detectors/detection systems were investigated in a laboratory research tunnel with various challenging fire scenarios.

P2.5.1 Long-Term Stability of the Low Energy Hydrogen Sensor

Anne-Kathrin Gerlitzke, Kai Nörthemann, Michael Lang, Werner Moritz, Ulrich Banach, Thomas Hübert, Michael Milstrey, Raig Kaufer & Michael Woratz
A silicon MIS-structure prepared with thin layers of the super-ionic conductor LaF3 and Pd is used to detect hydrogen. The sensor is able to detect hydrogen in a concentration range from below one ppm to the lower flammable limit in air which is 4 vol.-%. The chip operates at room temperature which results in an extremely low energy consumption compared to other hydrogen sensors. Only once per day a short heating pulse is necessary to...

Nanocrystalline Cellulose from Lignocellulosic Biomass: Applications and Future Prospects

F. Cotana, L. Brinchi, M. Gelosia, V. Coccia & A. Petrozzi
This review will present nanocrystalline cellulose, NCC, which is a cellulose derived nanomaterial that has received great academic and industrial interest over the last few years. The reported width is generally a few nanometers, while the length spans over a larger window, from tens of nanometers to some micrometers. NCC is promising as new class of bio¬based reinforcing material for the preparation of nanostructured composites due to impressive mechanical properties (in particular large tension modulus)...

Taiwan Area Mesoscale Experiment: A Guide to Precipitation Patterns During the 1987 Field Phase

Stanley Trier
This document summarizes radar reflectivity patterns in the Doppler radar coverage area during the field phase of the experiment. Its purpose is (1)to provide a condensed sample data set for scientists to aid in the selection of Doppler radar data to be used for scientific analysis, and (2) to provide investigators who are not necessarily interested in using Doppler radar data with a general summary of precipitation patterns during the experiment.

Die Beziehung der äolischen Decksedimente in Nordwestdeutschland zur nördlichen Lößgrenze

Helmut Siebertz
There is a more or less continuous boundary line of aeolian cover sediments along the North-West German hill country, known as the northern loess boundary, which is due to climatic-morphological factors. Aeolian sediments beyond this boundary line have hitherto been interpreted as a special facies („Flottsand", sandy loess) of loessial accumulations. Local field studies in the Lower Rhine area, however, revealed, that some aeolian sediments beyond the mentioned boundary must be considered as loess. As...

Environmental Benefits with Used Railway Sleepers Fuelling Xylowatt's Notar Gasification Technology

J.P. Damon, A. Bacq, B. Berger, P. Dubois, F. Bourgois & H. Jeanmart
With a share of about 40 to 50%, wooden sleepers are widely used across Europe on railways. Beside wood benefits on this application (CO2 storage, technical advantages, etc..), wooden sleepers also have a negative impact on the environment because of the preservative treatment that contains carcinogenic compounds. Classified as hazardous waste when removed, the valorization of the 0.5 to 1 million tons per year is under incineration directive. The lack of environmental effective solution and...
