spatial measurements of conductivity, temperature and depth were used to study salinity variations along the principal channels of the tidal hypersaline creek network in the vicinity of bushehr port, persian gulf during three 25- tidal cycles in both warm and cold months. salinity variations and tidal fluctuations were out of phase throughout the short inverse estuary. the salinity values insid...

Set expansion refers to expanding a partial set of “seed” objects into a more complete set. One system that does set expansion is SEAL (Set Expander for Any Language), which expands entities automatically by utilizing resources from the Web in a language-independent fashion. In this paper, we illustrated in detail the construction of character-level wrappers for set expansion implemented in SEA...

Synchronous release of gametes or larvae by marine animals may be controlled by as many as four environmental cycles thereby enabling an array of reproductive timing patterns. Cohesive scenarios that account for the diversity of reproductive patterns are rare and tests of their adaptive significance have been even rarer. By exploiting plasticity in the timing of larval release, we isolated prox...

Data are expressed as median (IQR). Data are expressed as median (IQR). CVvt%, coefficient of variation of the tidal volume expressed as percentage.

Tidal streams are complex watercourses that represent a transitional zone between riverine and marine systems; they occur where fresh and marine waters converge. Because tidal circulation processes cause substantial turbulence in these highly dynamic zones, tidal streams are the most productive of water bodies. Their rich biological diversity, combined with the convenience of land and water tra...

© The Ecological Society of America www.frontiersinecology.org T wetlands such as salt, brackish, and freshwater marshes provide essential ecosystem services to society. Such services include functions associated with regulation, habitat, and production (Daily et al. 1997; de Groot et al. 2002). Positioned at the interface between land and sea, tidal marshes are uniquely suited to provide ecosy...

Harbor seals and gray seals are sympatric phocid pinnipeds found in coastal waters of the temperate and sub-Arctic North Atlantic. In the Northwest Atlantic, both species were depleted through a combination of subsistence hunts and government supported bounties, and are now re-occupying substantial portions of their original ranges. While both species appear to have recovered during the past 2 ...

To assess the air-tightness of physical containment level 3 (PC3) bio-containment facilities in Australia, the seal integrity of 18 PC3 facilities was quantified by means of an equilibrium pressure air-tightness test conducted at positive pressure. The results of the test, which measured the leakage of air from the facility, indicate a variation in the air-tightness of the tested facilities whi...

Tidal energy is the most foreseeable form of renewable energy. Tidal energy can be harnessed by tidal barrage, tidal fence and tidal current technologies. Present efforts are focused on diffuser augmented tidal turbines that exploit the kinetic energy of the tidal currents. The power output by a tidal turbine is directly proportional to the cube of velocity of incoming fluid flow. Thus, even a ...

The noninvasive measurement of infant lung function during unsedated sleep in infants has been a long-standing objective in paediatric respiratory medicine. This note reports on the design and performance of a head-out volume-displacement plethysmograph (VDP) that overcomes some of the limitations of traditional lung function apparatus. The VDP comprises a rigid acrylic box with an integral wat...
