Three channel

The cyclooxygenase active site lies at the end of a long, narrow, hydrophobic tunnel or channel. Three of the u-helices of the membrane-binding domain lie at the entrance to this tunnel. The... 

Chapter 4 is devoted to single-phase heat transfer. Data on heat transfer in circular micro-tubes and in rectangular, trapezoidal and triangular ducts are presented. Attention is drawn to the effect of energy dissipation, axial conduction and wall roughness on the thermal characteristics of flow. Specific problems connected with electro-osmotic heat transfer in micro-channels, three-dimensional heat transfer in micro-channel heat sinks and optimization of micro-heat exchangers are also discussed. 

Pore-size-dependent conductances are assigned to individual pores and channels. Three possible types of bonds befween pores exist. The corresponding bond conductances—(T), and o X)—can be established straightforwardly. The model was extended toward calculation of the complex impedance of the membrane by assigning capacitances in parallel to conductances to individual pores. The probability distribution of bonds to have conductivify cr b, <7br/ or O, is... 

Fig. 20.1 A three channel, three limit problem. Three levels of the ion, shown by the bold lines, have Rydberg series converging to them from below and continua above them. The interactions between the series are shown by the horizontal arrows. Bound-continuum interactions are shown by single headed arrows while bound interactions are shown by...

A brief review and reassessment of data on the photophysics of benzene has been presented by Pereira. Evidence for the l E2g valence state has been obtained by u.v. two-photon spectroscopy.Slow electron impact excites fluorescence in thin films of benzene at 77 K as well as emission from isomers." The fluorescence yields and quenching by chloroform of alkyl-benzenes and 1-methylnaphthalene after excitation into Si, Sz, and S3 states and after photoionization have been measured. The channel-three process has been reconsidered in terms of the effects of local modes and Morse oscillator potentials. Excited-state dipole moments of some monosubstituted benzenes have been estimated from solvent effects on electronic absorption spectra, Structural imperfections influence the photochemistry of durene in crystals at low temperatures. Relaxation time studies on excited oxido-substituted p-oligophenylenes have been made by fluorescence depolarization...

Also within the cytoplasm and visible in the electron microscope and separable by appropriate centrifugation procedures, is a system of disc-shaped, membrane-bound channels, three to twelve in number, stacked together to form the Golgi bodies, so called after an Italian microscopist of the late nineteenth century. These Golgi bodies are especially well developed in cells which are specialized for the production and secretion of substances like hormones, and they may be involved in packaging substances prior to extrusion from the cell.

The lower is the entropy of the intensity distribution, the more rapid is the increase of the cumulative probability.37 Figure 5 compares the results for two bands in2,38 C6D6 with the results for the distribution (2.17) at the same value of the total strength . For the band where quantum numbers can be assigned, each transition can be identified and no lines are missing, the cumulative distribution of the experimental results increases more rapidly than that for the most entropic intensity distribution. Not so for the band that is in the channel three region2 where intramolecular energy transfer is quite dominant. A similar behavior is found also for computational results.13 As a practical point, it is necessary to mention that for the purpose of this...

Fig. 6.15 The Sortex 3400 machine is a compact design with two single channels. Three sensors surround each of the two channels providing all-round inspection and therefore a highly efficient sort. The 3400 is particularly suited to sorting low volumes of high-value commodities, since the yield and efficiency of the machine is very high.

Fluids have the same density in the four channels (three inlet channels and one outlet channel)...
