SUMMARYThe fire structural response of sandwich composite laminates incorporating bio-derived constituents subjected to a turbulent flaming fire was investigated. Fire structural tests were conducted on thermal insulated sandwich composites incorporating a thin surface-bonded non-woven glass fibre tissue impregnated with char-forming fire retardant, ammonium polyphosphate. The sandwich composite laminates were loaded in compression at 10%, 15% or 20% of the ultimate compressive strength while simultaneously subjected to turbulent flames imposing an incident heat flux of 35 kW/m 2 . Generally, the failure time increased with the reduced applied compressive load. The thermal insulated sandwich composite laminates had considerably improved fire resistance in comparison to their unmodified counterparts. The unmodified composites failed 96 s earlier than the thermal insulated specimens when the compression load was 10% of the ultimate compressive strength. The presence of ammonium polyphosphate at the heat-exposed surface promoted the formation of a consolidated char layer, which slowed down heat conduction into composite laminate substrate. The fire reaction parameters measured via the cone calorimeter provided insights into the thermal response hence fire structural survivability of sandwich composite laminates.

A highly scalable combined modular and 3D-printed falling film crystallization device is developed and demonstrated herein; the device uses a small, complex, printed overflow-based film distribution part that ensures formation of a well-distributed heated liquid film around a modular, tubular residence time/crystallizer section, enabling extended residence times to be achieved. A model API (ibuprofen) and impurity (ibuprofen ethyl ester) were used as a test system in the evaluation of the novel crystallizer design. The proposed crystallizer was run using three operational configurations: batch, cyclical batch, and continuous feed, all with intermittent removal of product. Results were suitable for intermediate purification requirements, and stable operation was demonstrated over multiple cycles, indicating that this approach should be compatible with parallel semicontinuous operation for intermediate purification and solvent swap applications in the manufacture of drugs.

A low-cost, modular, robust, and easily customisable continuous liquid–liquid phase separator has been developed that uses a tubular membrane and annular channels to allow high fluidic throughputs while maintaining rapid, surface wetting dominated, phase separation.

under the auspices of The Institute of Materials, Minerals and Mining. The meeting, which was highly successful, set new standards for the organisation of this important international conference, which had not been held in the UK since the 1980's. The organisers had been campaigning, against strong international competition, to have Edinburgh as the venue for well over a decade. In terms of atmosphere, international gravitas and, for most of the time, the weather the city and venue did not disappoint.

AbstractThe 2010 Highway Safety Manual (HSM) provides methods for predicting the number of motor vehicle crashes on various roadway facilities (AASHTO, 2010). However, it includes only a simplistic method for predicting the number of bicycle-related crashes. The research team investigated the bicycle-specific crash data in eight potential study areas around the U.San Diego, CA (county). The available online data from each were compared. The study city for future analysis (Boulder) was selected based on the availability of not just crash data but also the availability of continuous and short-duration bicycle and pedestrian traffic count data.In this analysis, a negative binomial model with log link was used to predict annual, non-fatal, motorist-bicyclist crashes on road segments per mile. This report adopts methods from the HSM used for motor vehicle safety performance functions (SPFs) in order to develop bicyclespecific SPFs for roadway segments in Boulder (9). The analysis shows that motor vehicle volume is a leading factor associated with more crashes between motor vehicles and bicyclists. Bicyclist exposure, population density, and percent retail land use are also predictive. While both vehicle volume and bicycle volume data are used in the model in order to account for the "safety in numbers" effect, the model did not demonstrate this effect that is seen so commonly in other research, including the bicycle SPF developed previously for intersections in Boulder (11). This effort at developing a bicycle-specific SPF for segments in the U.S. that utilize bicycle volumes is an important first step towards further understanding bicyclist safety and may inform future versions of the HSM. To that end, the report includes a table of motorist-cyclist crashes predicted by the model for various values. The authors hope this table may serve as a potential format template and starting point for future efforts to generalize the results of models for possible use in HSM updates. 17.
