Based on the small deflection theory, the lateral motion equation of a marine riser conveying flowing fluid subjected to environmental loads is developed by use of finite element method.

To obtain pyrolysis characteristics of medical waste compositions containing PVC(polyvinyl chloride),thermogravimetric study of tube for transfusion(TFT) and sample collector for urine(SCFU) was carried out using the thermogravimetric analyser(TGA) with N_2.

To obtain co-pyrolysis characteristics of medical wastes containing polyvinyl chloride(PVC)and biomass,co-pyrolysis experiments on mixtures of tube for transfusion(TFT)and gauze at different mass proportions,whose main ingredients were PVC and cellulose respectively,were carried out in an atmosphere of N2 using the thermogravimetric analyser(TGA.

By using Harmilton's principle and Euler's theory of elastic beam and taking Coriolis force of fluid into consideration,this paper builds the mathematical model for the problem on free vibration of elastic pipe conveying fluid,employs the Galerkin approach to find solutions to the model,analyzes the solutions and obtains corre.

The general expression for the instantaneous potential energy functional of elastic system is given at first, and then the special for the arbitrarily curved and twisted pipe conveying fluid is obtained.

Effect of human oviductal fluid and oviductal epithelial cell cultural medium on human sperm acrosome reactions;

Objective:To investigate the effect of the secretory proteins of the ventral prostate on the glycoproteins in the oviductal fluid of golden hamsters.

The vibration equations and finite element analysis model of the curved pipes conveying fluid are constructed and the dynamics of curved pipes under the boundary conditions of cantilever pipe are investigated also.

Analyzing the stability of curved pipes conveying fluid by high precise direct integration method (HPD) is a new attempt.
