Protein crystallization in vivo
Protein crystallization in vivo provides some fascinating examples of
biological self-assembly. Here, we provide a selective survey to show the
diversity of functions for which protein crystals are used, and the physical
properties of the crystals thatare exploited. Where known, we emphasize how the
nature of the protein-protein interactions leads to control of the
crystallization behaviour.Comment: 17 pages, 1 figur
Design and evaluation of an integrated Quiet, Clean General Aviation Turbofan (QCGAT) engine and aircraft propulsion system
The design was based on the LTS-101 engine family for the core engine. A high bypass fan design (BPR=9.4) was incorporated to provide reduced fuel consumption for the design mission. All acoustic and pollutant emissions goals were achieved. A discussion of the preliminary design of a business jet suitable for the developed propulsion system is included. It is concluded that large engine technology can be successfully applied to small turbofans, and noise or pollutant levels need not be constraints for the design of future small general aviation turbofan engines
