Since the 1990s, private sector participation through Public-Private Partnerships, PPPs model has started in airport construction, modernization, and operation India. Major international airports like IGIA, Indira Gandhi at Delhi, CSIA Chhatrapati Shivaji Mumbai, Cochin Kochi, etc., are successful examples of implementation. This research focuses on Indian approach privatization, with a specifi...

A multi-commuted flow system coupled to a gas diffusion device was developed for the spectrophotometric determination of ammonium nitrogen in sea and estuarine waters. The efficiency of complexing agents to prevent precipitation of metallic hydroxides, due to the high pH value of the carrier solution, was studied. Under the optimised conditions, no interference was observed from different expec...

This is the first study analyzing Pacific oyster microbiota in the Puget Sound estuarine system using a next-generation sequencing method. Taxonomic analysis indicated that Tenericutes, Chlamydiae, Proteobacteria, and Firmicutes were the most abundant phyla. Small numbers of operational taxonomic units (OTUs) belonging to the Vibrio genus were detected in all the oyster microbiome samples.

We have designed and implemented a comprehensive study of a major, land-estuarine system in the Acadian biogeographic province in eastern New England (Fig 1). Our goal is to develop a predictive understanding of the long-term response of watershed and estuarine ecosystems at the land-sea interface to changes in climate, land use and sea level and to apply this knowledge to the wise management a...

A three-dimensional hydrodynamic model that includes a Lagrangian particle-tracking simulation was applied to the Danshuei River estuarine system in northern Taiwan. The model’s accuracy was validated with data from1999; the results from themodel agreedwellwith empirical observations ofwater surface elevation, tidal currents, and salinity. The validatedmodelwas then used to investigate the resi...

BACKGROUND Human activities have increased atmospheric concentrations of carbon dioxide by 36% during the past 200 years. One third of all anthropogenic CO(2) has been absorbed by the oceans, reducing pH by about 0.1 of a unit and significantly altering their carbonate chemistry. There is widespread concern that these changes are altering marine habitats severely, but little or no attention has...

A screening-level aquatic probabilistic risk assessment was completed to determine the potential risks of organic pesticides found in surface waters of the C-111 freshwater basin (11 sites at the east boundary of the Everglades National Park) and adjacent estuarine tidal zones (two sites in northeast Florida Bay, one site in south Biscayne Bay) in south Florida. It followed the US Environmental...
