Characteristically shaped bifacial points are stone artefacts with which the Middle Stone Age Still Bay techno-complex in Southern Africa is identified. Traditional approaches such as chaîne opératoire and two-dimensional metrics in combination with attribute analyses have been used to analyse variability within Still Bay point assemblages. Here we develop a protocol to extract and analyse high...

Membrane-filtered bay water can support a certain degree of growth of Escherichia coli organisms isolated from the bay water or from sewage. The effect of the growth medium (bay water versus rich medium) on sensitivities to antimicrobial agents and cell envelope proteins was studied in many of these strains. Bay water-grown cells were less sensitive to bacteriophages and colicins, but were more...

Aqueous concentrations of nickel in the southern component of San Francisco Bay (South Bay) have periodically exceeded the water-quality criteria (8.2 ppb Ni) established in accordance with the EPA’s Clean Water Act. Nickel-rich serpentinite formations around the San Francisco Bay-estuary, particularly South Bay, are eroded, transported and accumulated in estuarine sediments, providing a natura...

Nearly 2 million people live in the Tampa Bay region, and the bay is the largest estuary in the State of Florida. The bay is home to the third largest port in the United States (in terms of domestic tonnage), and nearly 100,000 recreational boats are registered to owners in the counties surrounding the bay. Tampa Bay is also home to approximately 40,000 breeding pairs of shorebirds and over 100...

The in vitro activity of Bay 09867, a new quinoline derivative, was compared with those of norfloxacin, nalidixic acid, ceftazidime, cefaclor, cefuroxime, gentamicin, and other antimicrobial agents, when appropriate, against 410 recent clinical isolates. The minimal inhibitory concentrations of Bay 09867 for 90% of Enterobacteriaceae, Pseudomonas aeruginosa, Haemophilus influenzae, Neisseria go...

Several years of sea surface temperature data (1997–2003) for the coast of Antofagasta Bay—a semi-enclosed bay in northern Chile—were analyzed in order to further exploring the nature of a warm-water retention pattern inside the bay. Based on time series techniques, we were able to confirm the persistence of warm water in the bay. This warm feature was found immediately downwind of the upwellin...

A comparative study of the bacterial flora of the water of Chesapeake Bay and Tokyo Bay was undertaken to assess similarities and differences between the autochthonous flora of the two geographical sites and to test the hypothesis that, given similarities in environmental parameters, similar bacterial populations will be found, despite extreme geographic distance between locations. A total of 1...

macrobentos frequency and biomass was investigated in the gorgan bay in 2011. five sampling sites were chosen to collect benthos and sediment from the bay using a van veen grab sampler. samples were collected seasonally. macrobenthos were indentified and their biomass was recorded. sediment heavy metals concentration were measured using atomic absorption spectroscopy. a total of 11 families bel...

common carp ( cyprinus carpio ) population has been declined in the caspian sea in the recent years, mainly due to human manipulation. this valuable species needs to be protected in the caspian sea. considering the commercial value of common carp, its rehabilitation program has been established. in the present study, 8 microsatellite loci were used to assess genetic variation and population str...
