Obviously, it seems that his intention is to make another kind of voice out of the deep water, which makes it fight against traditional phalloccntrism; while also entangle on the male dcsire peering at female bodies in his narrative words, using the supposing visual center in the film picture to disguise the ubiquitous male desire peering at female bodies, all which embody the desire to close the western cultural center regardless of the picture handling and cameral lens cutting. Finally, he spends every strain to alleviate visual pressure and catering to the visual feeling of the western audience using narrative tactics, while the real intention to fight for language right with traditional phallocentrism. So it"s safe to say that this is a right fight between traditional phallocentrism and marginal counterpart. Just as the sacrifice of women in Zhang"s films, the marginal women again betrayed in Lous, and women again become the punishing and desire subject and swapping subject between men.

Using phalloidium staining we observed a sharp disappearance of the actin stress fibers, formation of extensive microvilli as demonstrated by the scanning microscopy and formation of typical bile canaliculi structures as confirmed by a monoclonal antibody to aminopeptidase N which is a BC specific antigen. The appearance of microvilli and BC suggested that selenium is able to elicit a differentiation reprogramming.

The free radical scavenging properties of six Aloe species are to be investigated in some modified chemical system. The antioxidant was purified by silica column and thin layer chromatography and analyzed by HPLC. A fraction was purified from A. brevifolia Mill showed the most effective scavenging activities on 〓 and ·OH (66. 01% and 38. 98% respectively). With the analysis of IR spectrum, UV spectrum and mass spectrum, the structure of FA was identifed as 8-C-D-glucopyranosyl-2- [2-hydroxy] propyl-5-methyl-7-hydroxychromone. Its scavenging activity on free radicals is higher than that of aloe-emodin. Its antioxidant activity may be due to the phenoxyl on glucosyl chromone which can be react with free radicals and form relatively stable free radicals.

Methods The compound preparation was administered intragastrically in mice, whose spontaneous activity was observed along with their tolerance of the preparation after long-term administration. The hypnotic effect of the compound was assessed by investigating the changes in the pentobarbital sodium-induced sleeping. The compound was tested for its antiseizure effect in mice with pentetrazole-induced clonic and tonic convulsion. Diazepam was used as the standard control in all experiments.

This dissertation investigates the construction of pseudo-random sequences (pseudo-random numbers) from elliptic curves and mainly analyzes their cryptographic properties by using exponential sums over rational points along elliptic curves. The main results are as follows:(1) The uniform distribution of the elliptic curve linear congruential generator is discussed and the lower bound of its nonlinear complexity is given.(2) Two large families of binary sequences are constructed from elliptic curves. The well distribution measure and the correlation measure of order k of the resulting sequences are studied. The results indicate that they are "good" binary sequences which give a positive answer to a conjecture proposed by Goubin et al.(3) A kind of binary sequences from an elliptic curve and its twisted curves over a prime field F_p. The length of the sequences is 4p. The "1" and "0" occur almost the same times. The linear complexity is at least one-fourth the period.(4) The exponential sums over rational points along elliptic curves over ring Z_ are estimated and are used to estimate the well distribution measure and the correlation measure of order k of a family of binary sequences from elliptic curves over ring Z_.(5) The correlation of the elliptic curve power number generator is given. It is proved that the sequences produced by the elliptic curve quadratic generator are asymptotically uniformly distributed.(6) The uniform distribution of the elliptic curve subset sum generator is considered.(7) We apply the linear feedback shift register over elliptic curves to produce sequences with long periods. The distribution and the linear complexity of the resulting sequences are also considered.
