    Notes: The retarded solution to the inhomogeneous wave equation in electrodynamics is studied with a purpose to understand Wu's missile and subsequently the radial dependence of energy transmitted by transient sources. The finite rate of change of the source current is shown to imply the inverse-square law at a sufficiently large distance, the region of which is determined by the minimum scale time tm of the current and may be called the (generalized) Fraunhofer region. With a uniform disk source, the electric field on the symmetry axis for a wide range is shown equal to the difference of the current at two times. Hence, examples with analytic results are given to demonstrate clearly how the pulse energy decreases with distance at a much slower rate in the (generalized) Fresnel region and how the inverse-square dependence is recovered in the farther region. Moreover, Wu's current profile, though with infinite slopes, is a Lighthill's generalized function and missiles refer to the transmitted pulses in the limit of zero tm which gives an infinite Fresnel region. A square temporal profile and other profiles with a sudden rise (or fall), including Samaddar's single-cycled cosine, which also generate missiles with an inverse-linear dependence, are studied. © 1999 American Institute of Physics.

    Notes: The Lighthill–Giles [Philos. Trans. R. Soc. London Ser. A 252, 397 (1960); J. Plasma Phys. 19, 201 (1978)] method is extended to evaluate the far field resulting from a moving radiating source in an anisotropic and dispersive medium, and the result thus obtained has a retardation interpretation. The radiation energy flux derived from the J⋅E method, only after a modification resulting from anisotropy of the medium and a correction factor resulting from retardation, is found to be compatible with that directly calculated from the far field, provided interference may be neglected. While the interference, which arises from the mixed product of any two far-field terms of different wave vectors, is demonstrated to be completely null in a uniaxial medium for a stationary source, it is shown to exist in a gyrotropic magnetoplasma and the total Poynting vector could be substantially nonradial in certain special cases.

    Notes: A general method recently developed [Phys. Fluids 29, 1881 (1986)] is applied to calculate analytically the far field and the radiation flux caused by a current source moving in each of a uniaxial nondispersive medium, an isotropic cold plasma, and a cold plasma in an infinite magnetic field. Explicit expressions in terms of space and time are obtained, and particular attention is paid to the complex Doppler situation and the Cerenkov case with and without dispersion.

    Notes: The ipomoelin (IPO) gene, a wound- and methyl jasmonate-inducible gene, was isolated from sweet potato (Ipomoea batatas cv. Tainung 57), and previously demonstrated to be regulated by dephosphorylated proteins and calcium ion (Chen Y.-C. et al. Plant Cell and Environment 26, 1373–1383, 2003). In this report, the function of the IPO protein was further studied. The IPO gene was characterized as having one intron and presenting two copies within the genome of sweet potato. The IPO protein appeared 1 d after the leaves of sweet potato were wounded. Surprisingly, the accumulation of the IPO protein remained for 7 d after wounding. Additionally, after the IPO protein was fused to a histidine tag, the His-IPO fusion protein produced from Escherichia coli BL21DE3 was then used to perform the haemagglutination test, which demonstrated that His-IPO fusion protein agglutinated human blood cells. Furthermore, several carbohydrates, including methyl α- d-glucopyranoside, methyl α- d-mannopyranoside, maltose, mannose, glucose, galactose, and lactose, reduced the efficiency of the His-IPO fusion protein in agglutinating human blood cells. These experimental results may indicate that the IPO protein is a lectin, a carbohydrate-binding protein. Notably, the IPO protein retarded the growth and development of silkworm, and thus reduced silkworm survival rates. Therefore, these findings indicate that the function of the IPO protein is to protect plants from insect attack.

    Notes: The effects of concentration, type and level of ingredients, heat and freeze/thaw treatments on the water mobility of starch-based fat re-placers were investigated. Water mobility in the starch-based fat re-placer samples containing gums, proteins or emulsifiers was similar to that of samples without additional ingredients. Water mobility was not affected by heat treatment, but was increased by freeze/thaw treatments. Water mobility in the solute containing samples was lower than in samples without additional ingredients and changed only slightly after heat and freeze/thaw treatments.

    Notes: : In this study, microbial transglutaminase (MTGase) was employed to modify viscoelasticity of wheat flour dough. Three flours, namely In-, Mid-, and Out-flour derived from different parts of wheat kernel, were used. When adding 16 ppm MTGase, the maximum resistance to extension (Rmax) of In-(58%), Mid-(56%), and Out-flour(52%) doughs, prepared at specific water levels indicated in parentheses, is increased by 51%, 35%, and 77%, respectively. The extensibility (E) of these 3 doughs is reduced by 16%, 11%, and 6%; the stickiness is also lowered by 12%, 5%, and 22%, respectively. SDS-PAGE analysis indicates that crosslinks occur within wheat gluten of MTGase-treated dough.
