Media Effect of Students’ Ideological and Political Work in Tibetan Agricultural Colleges and Universities

Both the students’ ideological and political work and the media work in agricultural colleges and universities are priorities of agricultural higher education in Tibet. The economic and social development situation in Tibet,especially the modern agricultural development trend in Tibet,provides excellent development opportunities and challenges for both the students’ ideological and political work and the media work in Tibetan agricultural colleges and universities. On the whole,the students’ ideological and political work and the media work should not be treated with discrimination. Instead,they should be effectively integrated and coordinated,to form joint efforts,so as to create a bright spring for agricultural higher education of Tibet.

Diversified effective stress laws for multi-porosity are developed.

Effects of NO and Different Media on the Growth of Prorocentrum micans

Prorocentrum micans was cultivated in different media including f/2, f/4, f/8, f/20, f/25, f/50, f/100 and f/200. Results showed that media influence the growth of P.micans. The biomass of P.micans in rich nutrition medium was much higher than in poor nutrition medium. Nitric oxide can promote or inhibit the growth of P.micans in all media. Nitric oxide at the concentration of 1.4×10 -6 mol L -1 promoted the growth of P.micans significantly when added only once during the cultivation. When added twice a day, nitric oxide at the concentration of 1.4×10 -9 mol [KG-*4]L -[KG-*5]1 promoted the growth of P.micans significantly, while nitric oxide at the concentrations of 1.4×10 -5 mol L -1 and 1.4×10 -6 mol L -1 inhibited the growth. Therefore, nitric oxide, media and the ways to add nitric oxide influenced the growth of P.micans respectively.

WAVE PROPAGATION WITH MASS-COUPLING EFFECT IN FLUID-SATURATED POROUS MEDIA

This article utilizes the theory of mixtures to formulate a general theory of wave propagation with mass-coupling effect in fluid-saturated porous media. An attempt is made to discuss the physical interpretation and the thermodynamic restriction of the coefficients appearing in the equations obtained, by the comparison it is shown that Biot's classical theory and the present one are essentially consistent. Also wave velocities in some special cases are calculated, from which it is concluded that mass-coupling and permeability of media greatly affect wave propagation behavior.

Pattern Structure of Deterministic Displacement in Random Porous Media with Dispersion Effect

A new model - modelof random porous media degradation via several fluid displacing, freezing, and thawing cycles is introduced and investigated in this paper. The fluid transport is based on the deterministic method with dispersion effect. The result shows that the topology and the geometry of the porous media have a strong effect on displacement processes. The cluster size of viscous fingering (VF) pattern in percolation cluster increases with the increase of iteration parameter n. When iteration parameter n ≥ 10, VF pattern does not change with n. We find that the displacement fluid forms trapping regions in random porous media with dispersion effect. And the trapping regions will expand with the increasing of the iteration parameter n. When r (throat size) → 1 and n ≥ 5, the peak value of the distribution Nmat(r) increases as n increases, where Nmat(r) is the normalized distribution of throat sizes after different displacement-damages but before freezing. The peak value of the distribution Ninv(r) reaches a maximum when n ≥ 10 and r = 1, where Ninv(r) is the normalized distribution of the size of invaded throat. This result is different from invasion percolation. It is found that the sweep efficiency E increases along with the increasing of iteration parameter n and decreases with the network size L, and E has a minimum as L increases to the maximum size of Iattice. The VF pattern in percolation cluster has one frozen zone and one active zone.

Fractal scaling of effective diffusion coefficient of solute in porous media

The results are consistent with the empirical equations analogous to Archie`s law and are expected to be applied to prediction of effective diffusion coefficient. Key words: diffusion; effective diffusion coefficient; fractal; porous media.

MULTIPLE SCATTERING THEORY OF EFFECTIVE MECHANICAL PROPERTIES OF INHOMOGENEOUS MEDIA

The rate of hydrothermal reaction of SiO_2 and/or A1_2O_3 in the system of CaO-Al_2O_3-SiO_2-H_2O at 200℃ and the factors which influence the reactions are investigated by determining the reaction ratio.The rate of reactions depends on the reactive activities of raw materials, initial composition of mixture and relative activity of SiO_2 and A12O3. The hydrothermal reaction can be accelerated by sodium hydroxide,in the case of silica,which has low activity, this is quite obvious.

The Use of Models to Evaluate Corrosion Effects on Mild Steel Heat Exchanger in Water and Mono Ethanol Amine (MEA)

Heat exchanger is an important equipment used in process industries for cooling and heating purposes. Its design configuration which involves the flow of cold and hot fluids within the exchanger subjects it to corrosion attack. The article utilized the principle of mass and energy conservation in the development of weight and temperature models to study the effect of corrosion on mild steel coupon inside the exchanger containing water and Mono ethanol amine (MEA). The models developed were resolved analytically using Laplace Transform and simulated using Excel as simulation tool and data obtained from experiment in the laboratory to obtain profiles of weight loss and temperature as a function of time. The weight loss and performance of mild steel under various corrosive conditions were examined which indicates the effect of corrosion on the mild steel heat exchanger in water and MEA media. The result shows that water is more corrosive than MEA at higher temperatures and at lower temperatures of 35°C and 1 atm, MEA has inhibitive properties than water as indicated by the weight loss result with time. The comparative analysis between the results obtained from the model simulation and experimental results shows that the result obtained from the model is more reliable and demonstrated better performance characteristics as it clearly shows mild steel heat exchanger experiences more corrosive effect in water medium than MEA at higher temperatures. And at lower temperatures, MEA becomes more inhibitive and less corrosive than water. The model simulation results correlate with various literatures and hence, it is valid for future referencing.
