Liquid-Liquid Equilibrium for 1-Butanol-Water-KF and 1-Butanol-Water-K2CO3 Systems

KF or K2CO3 was added into the 1-butanol-water system and two phases were formed： water-rich phase （water phase） and 1-butanol-rich phase （1-butanol phase）. The liquid liquid equilibrium （LLE） data for 1-butanol-water-KF and 1-butanol-water-K2CO3 systems were measured at 25℃ and showed that 1-butanol phase contained negligible salt and water phase contained negligible 1-butanol when the concentrations of KF and K2CO3 in the water phase were equal to or higher than 27.11% and 31.68% , respectively. Thus water could be separated efficiently from 1-butanol-water by adding KF or K2CO3 into the system. A theoretical calculation of LLE data was calculated by using the Pitzer theory to get water activity in the water phase, and by the models, such as the Wilson, NRTL or the UNIQUAC for the 1-butanol phase. For 1-hutanol-water-KF system, the experimental data were found in good agreement with the calculated results by using Pitzer theory and Wilson equa tion, while for 1-butanol-water-K2CO3 system, the experimental data were found in good agreement with the calculated results by using Pitzer theory and UNIQUAC eauation.

Iterative Method for Constructing Complete Complementary Sequences with Lengths of 2^mN

Complete complementary sequences are widely used in spectrum spread communications because of their ideal correlation functions. A previous method generates complete complementary sequences with lengths of N^nN （n,N ∈ Z^＋）. This paper presents a new iterative method to construct complete complementary sequences with lengths of 2^mN （m,N ∈ Z^＋）. The analysis proves that this method can produce many sequence sets that do not appear in sequence sets generated by the former method, especially shorter sequence sets. The result will certainly increase the application of complete complementary sequences in communication engineering and related fields.

Expression and Characterization of HGV E2 cDNA in Pichia pastoris

A 559 base pair fragment of cDNA locating at the putative E2 region of GBV-C/HGV was in-serted into Pichia pastoris expression vector pPICgK in the reading frame of α-factor secreting signal pep-tide. The recombinant expression plasmid pPIC9K-E2 was introduced into P. pastoris GSll5 with electro-poration and recombined with the host genome by homological recombination. The His+Mut+ recombinantyeasts were selected and cultivated in the BMMY medium. After 3 days induction with 0. 5% methanol,the target protein(E2) accumulated up to 30% of total proteins in the supernatant. The expressed E2 pro-tein was proved possessing antigenicity and high specificity with Western blot and ELISA probed with serafrom the immunized rabbits and the patients infected by GBV-C/HGV.
