Abstract Updating a finite-element (FE) model using dynamic parameters obtained from field testing requires an adequate understanding of the variation such due to changes in environmental conditions. This paper presents experimental program study influence water–structure interaction response prestressed concrete segmental bridge with partially submerged piers artificial reservoir. The bridge, ...

Abstract Submerged floating tunnel (SFT) is a new type of structure across long and deep water straits waterways with good application prospects. The different from the traditional large-span bridges immersed tunnels, which can effectively avoid difficulty under construction foundation in channel, high cost large span bridge, influence typhoons heavy fog et al. severe weather on vehicle driving...

Respiratory activities were compared among rice seedlings germinated in air for 6 days (aerobic seedlings), those germinated under water for 5 days (submerged seedlings), and those grown in air for 1 day after 5 days' submerged germination (air-adapted seedlings). The respiratory activity of the submerged seedlings increased rapidly on transfer to air and reached a plateau at 16 hours in air. R...

BACKGROUND AND AIMS Submergence and de-submergence are common phenomena encountered by riparian plants due to water level fluctuations, but little is known about the role of physiological integration in clonal plants (resource sharing between interconnected ramets) in their adaptation to such events. Using Alternanthera philoxeroides (alligator weed) as an example, this study tested the hypothe...

OBJECTIVE To evaluate bone-level alterations that occurred at implants of the Astra Tech(R) System that were placed in the load carrying, posterior parts of the dentition using either a submerged (two-stage) or a non-submerged (one-stage) installation protocol. MATERIAL AND METHODS Eighty-four patients that required 115 fixed partial dentures (FPDs or cases) entered the prospective study. All...
