Strategic Guidance Effect of Large-Scale Construction Enterprise Growth to Programme Contracting

Feng Guo,Yi-qi Chen,Yi-qing Cai

Frontiers of Engineering Management 2016, Volume 3, Issue 3,   Pages 246-251 doi: 10.15302/J-FEM-2016034

Abstract: In the case of single project management standing the major place, the management on the organizational level and project level is separated from each other in large-scale construction enterprises, and it is not long before program management theories applied to construction industry. Under the new situation of construction project clustering, how to choose projects has been the strategic decision for construction enterprises. Therefore, with the theory of program management and strategic management, this paper analyzes the relationship between the strategic growth of large-scale construction enterprises and program contracting, and attempts to provide meaningful ideas for enterprises to choose program from the strategic level.

The effect of pH, solid content, water chemistry and ore mineralogy on the galvanic interactions between

Asghar Azizi, Seid Ziaoddin Shafaei, Mohammad Noaparast, Mohammad Karamoozian

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 4,   Pages 464-471 doi: 10.1007/s11705-013-1356-z

Abstract: The role of pH, solid content, water chemistry and ore mineralogy on the galvanic interactions between chalcopyrite and pyrite and low alloy steel balls were investigated in the grinding of Sarcheshmeh porphyry copper sulfide ore. All these factors strongly affect the galvanic current between the minerals and the steel during the grinding process. The galvanic current density decreased as the solution pH and percent solids increased. In addition, changing the water in the ball mill from tap to distilled water reduced the galvanic current between the minerals and the balls. Potentiodynamic polarization curves showed that pyrite and chalcopyrite demonstrated typical active-passive-transpassive anodic behavior in the grinding of copper ore. However, the nature of their transitions from the active to the passive state differed. This behavior was not seen in the grinding of pure minerals. In addition, an EDTA extraction technique was employed to quantify the amount of oxidized iron in the mill discharge. The amount of extractable iron was influenced by the same experimental factors and in the same way as the galvanic current.

Keywords： steel ball     galvanic interaction     pyrite     chalcopyrite     polarization curves

Effect of seismic wave propagation in massed medium on rate-dependent anisotropic damage growth in concrete

Alireza DANESHYAR, Hamid MOHAMMADNEZHAD, Mohsen GHAEMIAN

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 2,   Pages 346-363 doi: 10.1007/s11709-021-0694-z

Abstract: Seismic modeling of massive structures requires special caution, as wave propagation effects significantly affect the responses. This becomes more crucial when the path-dependent behavior of the material is considered. The coexistence of these conditions renders numerical earthquake analysis of concrete dams challenging. Herein, a finite element model for a comprehensive nonlinear seismic simulation of concrete gravity dams, including realistic soil–structure interactions, is introduced. A semi-infinite medium is formulated based on the domain reduction method in conjunction with standard viscous boundaries. Accurate representation of radiation damping in a half-space medium and wave propagation effects in a massed foundation are verified using an analytical solution of vertically propagating shear waves in a viscoelastic half-space domain. A rigorous nonlinear finite element model requires a precise description of the material response. Hence, a microplane-based anisotropic damage–plastic model of concrete is formulated to reproduce irreversible deformations and tensorial degeneration of concrete in a coupled and rate-dependent manner. Finally, the Koyna concrete gravity dam is analyzed based on different assumptions of foundation, concrete response, and reservoir conditions. Comparison between responses obtained based on conventional assumptions with the results of the presented comprehensive model indicates the significance of considering radiation damping and employing a rigorous constitutive material model, which is pursued for the presented model.

Systems understanding of plant–pathogen interactions through genome-wide protein–protein interaction

Hong LI,Ziding ZHANG

Frontiers of Agricultural Science and Engineering 2016, Volume 3, Issue 2,   Pages 102-112 doi: 10.15302/J-FASE-2016100

Abstract: Plants are frequently affected by pathogen infections. To effectively defend against such infections, two major modes of innate immunity have evolved in plants; pathogen-associated molecular pattern-triggered immunity and effector-triggered immunity. Although the molecular components as well as the corresponding pathways involved in these two processes have been identified, many aspects of the molecular mechanisms of the plant immune system remain elusive. Recently, the rapid development of omics techniques (e.g., genomics, proteomics and transcriptomics) has provided a great opportunity to explore plant–pathogen interactions from a systems perspective and studies on protein–protein interactions (PPIs) between plants and pathogens have been carried out and characterized at the network level. In this review, we introduce experimental and computational identification methods of PPIs, popular PPI network analysis approaches, and existing bioinformatics resources/tools related to PPIs. Then, we focus on reviewing the progress in genome-wide PPI networks related to plant–pathogen interactions, including pathogen-centric PPI networks, plant-centric PPI networks and interspecies PPI networks between plants and pathogens. We anticipate genome-wide PPI network analysis will provide a clearer understanding of plant–pathogen interactions and will offer some new opportunities for crop protection and improvement.
