A reliable, feasible finite element analysis model for multi-pin-hole connected structure with multi-cracks was established with contact between pin and the conjunctional structure.

Results Compared with CNE2 and CNE2-LNSX cells,CNE2-LMP1 cells morphologically changed from typical epithelial appearance to long-spindle fibroblastic morphology with the concomitant loss of cell-to-cell contact, and relative migration of CNE2-LMP1 cells obviously increased (n=3, P< 0.05), while the expression of E-Cadherin was negative in CNE2-LMP1 cells.

BaPb_(1-x)Bi_xO_3 based thick film is actually conductive with lead and bismuth oxide, the main factors on the properties of thick film is the electric resistance and contact resistance of conductive particulates;

Conclusion:The proportion of CD4~+CD25~(high)Foxp3~+Treg cells was increased in lung cancer patients,which consequently resulted in the inhibition of immune response and tumor development.

It also increased the proton-conducting rate and improved the performance of SOFCs due to the reduction of membrane thickness and good contact between electrolyte and electrodes.

Another intercellular communication type, namely a physical contact between cells (cell aggregation), plays a key role in formation of biofilms or cellular consortia and in cell proliferation under unfavorable conditions.

The enzyme coupled via the oligosaccharide chain exhibited better access to the substrate casein as compared to the preparation in which the amino groups formed the point of contact between the enzyme and the polymer.

Influence of the Type of Contact between Particles Joined by a Liquid Bridge on the Capillary Cohesive Forces

A second-approximation solution for the pressure distribution between two elastic bodies in contact is presented. In addition to the terms used by Hertz as the description of a general surface of contact, the present theory will contain the next higher-order terms of its Taylor's series expansion, such that the coefficients of the Hertz second power terms as well as the dominant fourth-power term is satisfied. Hence, the second order effect is a correction to Hertz theory which increases both with the increase...

A second-approximation solution for the pressure distribution between two elastic bodies in contact is presented. In addition to the terms used by Hertz as the description of a general surface of contact, the present theory will contain the next higher-order terms of its Taylor's series expansion, such that the coefficients of the Hertz second power terms as well as the dominant fourth-power term is satisfied. Hence, the second order effect is a correction to Hertz theory which increases both with the increase of normal load and with the increase of eccentricity of the contact. ellipse. method of change of variables is adopted in the process of integration. The solution, thus obtained, agrees exactly with that obtained by Cattaneo when reduced to his special case of two solids of revolution in contact.To illustrate the usefulness of the present theory, the problem of contact between a ball and the outer race of a ball bearing is studied. Curves are plotted to show that the relative magnitude of the second order effect varies with the shape ratio of the contact ellipse at various normal loads.

In addition to the structural style, there are a lot of information about stratigraphy and sedimentology which hold in stock in the seismic sections. By making full use of them we can interprete what do they imply in the sense of stratigraphy and sedimentology. To this point it will be contributive as to make the depositional sequence subdivision properly, to recognize the sedimentary enviroument; to establish the depositional system; and to predict the potential oil trend in basins where well control is limited....

To this point it will be contributive as to make the depositional sequence subdivision properly, to recognize the sedimentary enviroument; to establish the depositional system; and to predict the potential oil trend in basins where well control is limited. Moreover the seismic stratigraphy method combine the characteristics of both stratigraphy and tectonic together simultaneously, it will be of great immediate significance for expounding the formation of basin as well as the development of mechanism.By taking advantage of the seismic stratigraphy method, the authors tried to make a reconsideration to basic concepts of the sedimentary enviroument of Eogene sediments in the Huanghua depression. Its results essentially are:

In this paper the statistical property of random vibration in the truck with rear bogie is discussed. Formulas are given for calculating the root-mean-square values of each of the following variables: Z(t)-the acceleration of the Vehicle body. N(t)-the contact force acting between the wheel and the road and δ(t)-the working space of the suspension.
