The damage caused by earthquake is irresistible for human beings, and the structure with poor robustness is most affected by earthquake. Especially when traffic arteries like bridges and highways are affected, the losses will be unimaginable. To reduce the loss in earthquake, the paper targets the long-span cable-stayed bridge and discusses a method of structural damage control. The energy-diss...

Abstract With the development of space science in China, scale application payloads continues to increase, and demand for heat dissipation is also gradually increasing. The fluid loop thermal control a more efficient way dissipation. In order optimize effect system, this paper establishes model system converts it into constrained optimization problem. generalized Lagrange multiplier method used...

Experimental work on the control of photosystem II in the photosynthetic apparatus of higher plants, mosses and lichens is reviewed on a background of current literature. Transmembrane proton transport during photoassimilatory and photorespiratory electron flows is considered insufficient for producing the intrathylakoid acidification necessary for control of photosystem II activity under exces...

In the present article, the reflection and transmission of plane waves at the boundary of thermally conducting micropolar elastic media with two temperatures is studied. The theory of thermoelasticity with and without energy dissipation is used to investigate the problem. The expressions for amplitudes ratios of reflected and transmitted waves at different angles of incident wave are obtained. ...

Several techniques and metrics based on the Second Law of Thermodynamics have been used in the past for the analysis of heat exchangers. The terms used for these techniques include irreversibility analysis, entropy generation minimization, exergy analysis and thermodynamic efficiency. Entransy is a recently developed concept reflecting the heat transfer potential, rather than the ability to con...

in this study, residues of imidacloprid (confidor) were measured in greenhouse cucumbers in mazandaran province, iran. confidor 200 sl was applied at the recommended rate (30.0 g ai ha-1) and its double (60.0 g ai ha-1). samples were collected at 1 h to 21 days after application and analyzed to determine the content and dissipation rate of imidacloprid. . analysis was carried out by the quecher...

The dissipation of absorbed light and potential for photooxidative damage was explored in Douglas-fir (Pseudotsuga menziesii ) seedlings with and without Phaeocryptopus gaeumannii infection. The presence of P. gaeumannii significantly reduced net CO2 assimilation rates from ca. 6 lmol/m/s to 1.5 lmol/m/s, without any significant impact on chloroplast pigments. The partitioning of absorbed light...
