  • CYP175A1 fromThermus thermophilusis a thermophilic cytochrome P450 and has great potential for industrial applications. However, a native elec-tron transport system for CYP175A1 has not been identified. Here, an elec-tron transport system for CYP175A1 was isolated from T. thermophilus HB27 by multistep chromatography, and identified as comprising ferre-doxin (Fdx; locus in the genome, TTC1809) and ferredoxin–NAD(P) + reductase (FNR; locus in the genome, TTC0096) by N-terminal amino acid sequence analysis and MALDI-TOF-MS, respectively. ...

  • The transportation system is a network of highways, trails, railroads, airports, transmission lines, pipelines, canals, and waterways set in the landscape. The goal of the transportation designer is to fit the highway or other facility into the adjacent landscape in a way that is complementary to, and enhances, the existing landscape. Achieving this goal requires consideration of natural, ecological, aesthetic, economic, and social influences related to that landscape.

  • All air-handling units (AHUs) and many terminal units, if they are not self-contained, require a source of heating and/or cooling energy. This source is called a central plant, and the means by which thermal energy is transferred between the central plant and the AHU is usually a fluid conveyed through a piping system. The fluids used in HVAC practice are steam, hot or cold water, brine, refrigerant, or a combination of these. The equipment used to generate the thermal energy is described in Chap. 7. In this chapter we discuss the transport systems. ...

  • The performance of current transport systems is inadequate when viewed in terms of economic efficiency, sustainability, and safety. Towards Better Performing Transport Networks examines the tools that are necessary to effectively measure these systems and those that are required to improve them. Utilising advanced tools of network analysis, the contributors challenge various pieces of conventional wisdom and in particular the view that intermodal transport is more environmentally benign than road transport.
