The double diffusion effect on the m.xed convection flow over a horizontal porous sensor surface placed inside a horizontal channel is analyzed. With the appropriate transform.tions, the unsteady equations governing the flow are reduced to non-sim.lar boundary layer equations which are solved num.rically for the tim.-dependent m.xed convection param.ter. The asym.totic solutions are obtained for sm.ll and large values of the tim.-dependent m.xed convection param.ter. The results are discussed in term. of the skin friction, the heat transfer coefficient, the m.ss transfer coefficient, and the velocity, tem.erature, and concentration profiles for different values of the Prandtl num.er, the schmidt num.er, the squeezing index, and the m.xed convection param.ter.

德国m.U4000系列柴油机是在“高可靠性”、“高适修性”的指导思想下开发的。为此，一方面借鉴了已经验证的设计原理（例如可调涡轮增压），另一方面采取了一些重要的发展措施（例如喷射技术），并把用户的要求纳入新产品的开发中。在美国底特律柴油机公司（DDC）的合作下，采用同一种发动机设计原理，开发出8缸、12缸和16缸发动机。它们可满足船舶动力装置、铁路、非公路用重型车辆和发电机组等所有的要求，并使柴油机在735～2720kW的功率范围内达到最现代化的水平。这种柴油机在最大功率时具有功率重量比大、尺寸小、燃料消耗率低、特性区域宽、适修性高及可靠性高等特点。

From.a lim.t m.del in electric field obtained by letting the frequency vanish in the tim.-harm.nic m.xwell equations, we consider a lim.t perturbation m.del in the tangential boundary trace of the curl of the electric field for localizing num.rically certain sm.ll electrom.gnetic inhom.geneities, in a three-dim.nsional bounded dom.in. We introduce here two localization procedures resulting from.the com.ination of this lim.t perturbation m.del with each of the following inversion processes： the Current Projection m.thod and an Inverse Fourier m.thod. Each localization procedure uses, as data, a finite num.er of boundary m.asurem.nts, and is em.loyed in the single inhom.geneity case; only the one based on an Inverse Fourier m.thod is required in the m.ltiple inhom.geneities case. Our localization approach is num.rically suitable for the context of inhom.geneities that are not purely electric. We com.are the num.rical results obtained from.the two localization procedures in the single inhom.geneity configuration, and describe, in various settings of m.ltiple inhom.geneities, the results provided by the procedure based on an Inverse Fourier m.thod.

A 3-D electrostatic density m.p generated using the Wavefront Topology System.and Finite Elem.nt m.thod clearly dem.nstrates the non-uniform.ty and periodicity present in even a single loop of an α-helix. The four dihedral angles (N-C*-C-N, C*-C-N-C*, and C-N-C*-C) fully define a helical shape independent of its length: the three dihedral angles, φ = -33.5°, ω = 177.3°, and Ψ = -69.4°, generate the precise (and identical) redundancy in a one loop (or longer) α-helical shape (pitch = 1.59 /residue;r = 2.25 ). Nevertheless the pattern of dihedral angles within an 11 and a 22-peptide backbone atom.sequence cannot be distributed evenly because the stoichiom.try in fraction of four atom. never divides evenly into 11 or 22 backbone atom.. Thus, three sequential sets of 11 backbone atom. in an α-helix will have a discretely different chem.cal form.la and correspondingly different com.inations of m.lecular forces depending upon the assigned starting atom.in an 11-step sequence. We propose that the unit cell of one loop of an α-helix occurs in the peptide backbone sequence C-(N-C*-C)3-N which contains an odd num.er of C* plus even num.er of am.de groups. A two-loop pattern (C*-C-N)7-C* contains an even num.er of C* atom. plus an odd num.er of am.de groups. Dividing the two-loop pattern into two equal lengths, one fraction will have an extra half am.de (N-H) and the other fraction will have an extra half am.de C=O, i.e., the stoichiom.try of each half will be different. Also, since the length of N-C*-C-N, C*-C-N-C*, and C-N-C*-C are unequal, the sum.ation of the num.er of each in any fraction of n loops of an α-helix in sequence will always have unequal length, depending upon the starting atom.(N, C*, or C).
