Articles which are to he discharged from the clean room (or elsewhere) to the aseptic area must he sterilized. To achieve this they should be transferred via a double-ended sterilizer (i.e. with a door at each end). If it is not possible, or required, that they be discharged directly to the aseptic area, they should be (i) double-wrapped before sterilization (ii) transferred immediately after sterilization to a clean environment until required and (iii) transferred from this clean environment via a double-doored hatch (where the outer wrapping is removed) to the aseptic area (where the inner wrapper is removed at the workbench). Hatchways and sterilizers should be arranged so that only one side of the entry into an aseptic area may be opened at any one time. Solutions manufactured in the clean room may be brought into the aseptic area through a sterile 0.22-/im bacteria-proof membrane filter.

The laser-induced breakdowns are caused by three consequent mechanisms [22] (i) tiie excitation of electrons in tiie conduction band by impact and multiphoton ionization (MPI), (ii) radiation-induced heating of tiie conduction-band electrons, and (iii) transfer of the plasma energy to the lattice. The key benefit of ultia-short femtosecond laser pulses lies in their ability to deposit energy in materials in a very short time interval. Heat diffusion is frozen during the interaction and the shock-like energy deposition leads to ablation for ultra-short pulses. This is because tiie pulse... 

The FucT III transfers an L-fucose unit from GDP-fucose onto the 4-OH-group of a galactosylated N-acetylglucosamine in an a-niode to give the Lewis trisaccharide or the sialyl-Lewis tetrasaccharide, respectively (Fig. 13). 

In contrast to FucT VI, the FucT III transfers L-glucose (entry 4), the charged 2-aminofucose [42] (entry 15) and 2-fluoro fucose (entry 2). This is particularly noteworthy with respect to results obtained by Wong and coworkers who have observed that GDP-2-fluorofucose is a potent inhibitor for the functionally closely related FucT V [97].

Complexes I and II transfer electrons from NADH and succinate, respectively, to UQ. Complex III transfers electrons from UQH2 to cytochrome c. Complex IV transfers electrons from cytochrome c to 02. The arrows represent the flow of electrons. 

Complex III transfers electrons from reduced coenzyme Q (UQH2) to cytochrome c. Because it contains two b-type cytochromes, one cytochrome Cj (cyt Cj), and one iron-sulfur center, complex III is sometimes referred to as the cytochrome bcj complex. The cytochromes (Figure 10.6) are a series of electron transport proteins that contain a heme prosthetic group similar to those found in hemoglobin and myoglobin. Electrons are transferred one at a time as each oxidized iron atom (Fe3+) is reversibly reduced to Fe2+. The movement of electrons from UQH2 to cytochrome c is a complex, multistep process. Because UQ is lipid-soluble, it diffuses within the inner membrane between the electron donors in complex I or II and the electron acceptor in complex... 

Our review would not be complete without a note on mycorrhizal phosphorus transport, which is another key microbial process in the phosphorus cycle. It consists of three distinct parts (i) fungal absorption of phosphorus from the soil solution (ii) translocation of phosphorus within extra-radical hyphae from the site of absorption to the site of exchange with the host plant and (iii) transfer from the fungus to the host plant [sensu Cooper and Tinker, 1981). This... 

Complex III is also known as coenzyme Q-cytochrome c reductase. It accepts electrons from reduced coenzyme Q, moves them within the complex through two cytochromes b, an iron-sulfur protein, and cytochrome Ci. Electron flow through Complex II transfers proton(s) through the membrane into the intermembrane space. Again, this supplies energy for ATP synthesis. Complex III transfers its electrons to the heme group of a small, mobile electron transport protein, cytochrome c.
