A heavy hammer or a small type of rocket is used to strike the pile top and the detectors are used to record vibra- tion graphs. An expression of higher degree of strain (deformation force) is introduced. It is testified theoretically that the displacement, velocity and acceleration cannot be obtained by simple integral acceleration and differential velocity when long displacement and high strain exist, namely when the pile phase generates a whole slip relative to the soil body. That is to say that there are non-linear relations between them. It is educed accordingly that the force P and displacement S are calculated from the amplitude of wave train and (dynamic) P-S curve is drew so as to determine the yield points. Further, a method of determining the vertical bearing capacity for single-pile is dis- cussed. A static load test is utilized to check the result of dynamic test and determine the correlative constants of dynamic-static P(Q)-S curve.展开更多

The effects of biaxial crystal-field described by two uniaxial anisotropy parameters Dx and Dy on the phase transition and specific heat and susceptibility are studied numerically. Some interesting results are observed in the system such as tricritical behavior depending sensitively on the strength of the biaxial crvstal-field.展开更多

The idea is to utilize optimized IP multicasting handoff (based on PIM SM), which is triggered by CDMA layer 2 functionality. An IP based cellular network model with WCDMA FDD air interface and IP based packet traffic is adopted. No special network entities and signaling for handoff are added in our network model. The simulation results show that low delay and low packet lost rate can be obtained.展开更多

The effect of the transverse crystal field on transition temperaturesis investigated numerically for the honeycomb (z = 3) and square (z = 4) lattices. The results show that there is notricritical point for the system.展开更多

N-terminal 28 amino acid residues of 40S ribosomal protein (RP), S24E that is N-acetylserine were replaced by hT(1 for the constitution of hT(1-RP fusion gene in order to express acetyllated thymosin α 1. And also,the Asn-Gly bond was designed to faciliate isolation of the target protein.The fusion gene was cloned into the expression vector, pPIC/9K. The constructs were transformed into HIS4 mutant strain GS115 by electroporation. Both SDS-PAGE analysis and Western blot analysis indicated that the fusion protein was expressed successfully.展开更多

Methods: Patients of AS enrolled in this study were 106 cases in Group A, who were persistently treated with traditional Chinese medicine and western medicine (TCM WM) for over 10 months, 48 cases in Group B treated with WM and 34 cases in Group C treated with non steroid anti inflammatory and analgesic agents. They were followed up for 2 years. Results: (1) Short term effect: The markedly effective rate in the 3 groups was 73.58%, 47.92% and 5.88% respectively, and the total effective rate was 96.23%, 87.50% and 41.18% respectively. The comparison of Group A with Group B and C showed significant difference, the effect in Group A was superior to that in Group B and Group C (χ 2=10.58, P <0.01 and χ 2=67.76, P <0.01 respectively). (2) Results of 2 year follow up: the recurrence rate in Group A was 18.37% (9/49), it was insignificantly different from that in Group B (7/23, 30.43%,χ 2=1.32, P >0.05), but significantly different from that in Group C (8/12, 66.67%,χ 2=11.19, P <0.01). Conclusion: Long term TCM WM therapy, which combined the advantages of Chinese and western medicine, was a practical method in treating AS with reliable effect, few side effects, and therefore is worth popularizing.展开更多
