DYNAMIC IMPLOSION OF UNDERWATER CYLINDRICAL SHELLS : Experiments and Computations
The implosion of an underwater structure is a dynamic event caused by the ambient constant pressure environment. It produces a short duration pressure pulse that radiates outwards and can damage adjacent structures. This paper presents results from a combined experimental/numerical study that aims to understand the underlying physics and establish the parameters that govern the nature of such p...
متن کاملNoise radiation from doubly periodic reinforced submerged plates
Almost all known structures are designed for low weight and high strength. For metal structures, especially aircrafts and underwater vehicles, this means reinforcement in the form of ribs. This paper presents an analytic model for the prediction of the acoustic scattered field from such rib-reinforced structures. The geometry is assumed to be that of an infinite elastic plate reinforced with a ...
متن کاملUnderwater Photosynthesis of Submerged Plants – Recent Advances and Methods
We describe the general background and the recent advances in research on underwater photosynthesis of leaf segments, whole communities, and plant dominated aquatic ecosystems and present contemporary methods tailor made to quantify photosynthesis and carbon fixation under water. The majority of studies of aquatic photosynthesis have been carried out with detached leaves or thalli and this sele...
متن کاملUnderwater Photosynthesis and Internal Aeration of Submerged Terrestrial Wetland Plants
Submergence impedes plant gas exchange with the environment. Survival depends upon internal aeration to provide O2 throughout the plant body, although short-term anoxia can be tolerated. During nights, plants rely on O2 entry from the floodwater and pO2 in roots declines so that some tissues become severely hypoxic or even anoxic. Underwater photosynthesis is the main daytime O2 source and also...
متن کاملA perspective on underwater photosynthesis in submerged terrestrial wetland plants
BACKGROUND AND AIMS Wetland plants inhabit flood-prone areas and therefore can experience episodes of complete submergence. Submergence impedes exchange of O(2) and CO(2) between leaves and the environment, and light availability is also reduced. The present review examines limitations to underwater net photosynthesis (P(N)) by terrestrial (i.e. usually emergent) wetland plants, as compared wit...
