Research on interaction between engineering harmony and engineering innovation

He Jishan,Wang Jin,Yu Zhen

Strategic Study of CAE 2008, Volume 10, Issue 12, Pages 4-9

Abstract:

Engineering is an important and complex activity during the process of human survival and development, and to enhance its management effectiveness is the key to ensure social development. The current engineering activities appears a series of discord and lack of innovation, such as less integrated innovation, frequent accidents, and so on. The core of enhancing the effectiveness of engineering management is that the manager can achieve interactive development of harmony and innovation on the basis of perfecting engineering harmony and innovation. It defines engineering harmony and innovation, and then proposes that harmony is the new starting point and final goal of innovation; conversely, innovation is the motive power for the maintenance of harmony, and the drive for achievement of a higher level of harmony. Research on interaction between harmony and innovation is conducive to change our traditional view of engineering innovation, pursuit the harmony in inner organization and harmony of engineering and ecological environment and meet the needs of sustainable development.

Mapping the structure-activity relationship of

Worawan PANPIPAT, Hasene KESKIN, Zheng GUO

Frontiers of Chemical Science and Engineering 2015, Volume 9, Issue 1, Pages 105-113 doi: 10.1007/s11705-015-1502-x

Abstract: The phase behavior of twelve synthesized -sitosteryl fatty acid esters with acyl moieties with different chain lengths (C2:0-C18:0) and different degrees of unsaturation (C18:1-C18:3) were investigated in pure and mixed Langmuir monolayers with phospholipids. The surface-pressure isotherms showed that short chain -sitosteryl fatty acid esters gave smaller mean molecular areas and had decreased monolayer stability and the long chain steryl esters did not produce collapsed plateaus. All the steryl esters displayed strong condensing effects, but there was a pronounced structural dependency: medium chain esters (C8 and C10) were less efficient than short and long chain esters. Atomic force microscopy imaging demonstrated that monolayers mixed with dipalmitoyl phosphatidylcholine (DPPC) displayed both DPPC-rich and steryl lipid-rich domains. However, the height and area differences between the two phases and the roughness and morphologic patterns were very dependent on the steryl lipid concentrations as well as the length, the degree of unsaturation and the molecular conformations of the acyl segments. These findings not only provide a better understanding of the interactions between phytosteryl hydrophobic derivatives and biomembranes, but also may be of general use for the design and engineering of phytosterol structural derivations for specific food and pharmaceutical applications.

Stress-strain relationship of concrete in freeze-thaw environment

ZOU Chaoying, ZHAO Juan, LIANG Feng

Frontiers of Structural and Civil Engineering 2008, Volume 2, Issue 2, Pages 184-188 doi: 10.1007/s11709-008-0029-3

Abstract: Adopting the ASTM C666 quick freeze-thaw method, freeze-thaw tests with the number of freeze-thaw cycles being 0, 100, 150, 200, 250, and 300, were carried out on eighteen concrete prism specimens, the frost-resistant level of which, reaches D300 grade. The internal micro-structures of these specimens were observed by means of scanning electron microscopy (SEM) in order to detect damages caused by the freeze-thaw action. Afterwards these frozen-thawed specimens were tested on monotonic axial load; stress-strain testing curves after the freeze-thaw action were obtained. The testing results show that with the increasing time of freeze-thaw cycles, both the internal micro-structures and the basic mechanical parameters, including the ultimate bearing capacity, the Poisson ratio and the modulus of elasticity, degenerate in various degrees. Finally, stress-strain theoretical curvilinear equations and correlated parameters relating to the loss of relative dynamic modulus of elasticity were proposed. These results provide great reference for further research on the behavior and the calculation model of concrete structures in a freeze-thaw environment.
