Background In aquaculture breeding, resistance against infectious diseases is commonly assessed as time until death under exposure to a pathogen. For some diseases, a fraction of the individuals may appear as ""cured"" (non-susceptible), and the resulting survival time may thus be a result of two confounded ...
Taxonomically diverse marine, freshwater and terrestrial organisms have evolved the capacity to synthesize, accumulate and metabolize a variety of UV-absorbing substances called mycosporine-like amino acids (MAAs) as part of an overall strategy to diminish the direct and indirect damaging effects of ...
Astaxanthin is a xanthophyll carotenoid present in microalgae, fungi, complex plants, seafood, flamingos and quail. It is an antioxidant with anti-inflammatory properties and as such has potential as a therapeutic agent in atherosclerotic cardiovascular disease. Synthetic forms of astaxanthin have been ...
AbstractDescription Typically, decommissioned platforms are safely removed and taken ashore for disposal per regulatory requirements. But an alternative for the Eugene Island 331A platform was for Shell to recycle and transform it into a valuable marine habitat as part of "Rigs-to-Reef". Application EI ...
Abstract Understanding oil slick migration in rivers is important for effective spill response because rivers provide essential services for household purposes e.g. fisheries, water supply, transport, socio-cultural activities and recreation. Rivers constitute the second most important source of household ...
Abstract Twenty years after the Exxon Valdez spill, weathered residual oil is still found in small, isolated lenses of subsurface sediments of a very small fraction of Prince William Sound shorelines. The ecological impact of this remaining oil still causes great concern and has been extensively studied ...
Abstract The aerial extent of the Haynesville Shale play has been analyzed with regard to regulatory and permitting processes such that unavoidable surface impacts can be planned in a manner that allows operators to minimize both risk and cost from operations in environmentally sensitive areas – the ...
Abstract Changes to U.S. offshore drilling safety and environmental regulations have been enacted post-Macondo and further changes are possible. New prescriptive rules for deepwater drilling will have a significant impact on drilling engineering, operations, and costs. Performance-based regulations ...
Leptothrix ochracea is a common inhabitant of freshwater iron seeps and iron-rich wetlands. Its defining characteristic is copious production of extracellular sheaths encrusted with iron oxyhydroxides. Surprisingly, over 90% of these sheaths are empty, hence, what appears to be an abundant population ...
In this study, we sought to investigate the biology (diet and reproduction) and ethnobiology (fishers knowledge and fishing spots used to catch snappers) of five species of snappers (Lutjanidae), including Lutjanus analis, Lutjanus synagris, Lutjanus vivanus, Ocyurus chrysurus, and Romboplites saliens ...
Background Lignin and hemicelluloses are the major components limiting enzyme infiltration into cell walls. Determination of the topochemical distribution of lignin and aromatics in sugar cane might provide important data on the recalcitrance of specific cells. We used cellular ultraviolet (UV) microspectrophotometry ...
As the global market for fisheries and aquaculture products expands, mislabeling of these products has become a growing concern in the food safety arena. Molecular species identification techniques hold the potential for rapid, accurate assessment of proper labeling. Here we developed and evaluated ...
Background Characterization of novel fusion genes in acute leukemia is important for gaining information about leukemia genesis. We describe the characterization of a new ETV6 fusion gene in acute myeloid leukemia (AML) FAB M0 as a result of an uncommon translocation involving chromosomes 12 and 15. Methods The ...
Interactions between pelagic thresher sharks (Alopias pelagicus) and cleaner wrasse were investigated at a seamount in the Philippines. Cleaning associations between sharks and teleosts are poorly understood, but the observable interactions seen at this site may explain why these mainly oceanic sharks ...
Background Studies on artificial hybridization of different Anguilla species were conducted recently, i.e. female A. australis with male A. dieffenbachii, and female A. japonica with male A. anguilla. The existence of these artificial hybrids was however not demonstrated by independent genetic methods. ...
ABSTRACT: 90-10 copper-nickel is one of the few engineering alloys available which offer both high resistance to seawater corrosion and biofouling. The alloy is not immune to microfouling but colonization of macrofouling is much restricted. The mechanism is not fully understood and is thought to be ...
ABSTRACT The traditional approach to corrosion modeling is relatively straightforward. Corrosion is expressed as a rate of penetration per year and failure is defined when a critical loss of section is predicted to have occurred. Such an approach is well suited to applications involving ships and pipelines ...
ABSTRACT The present work was carried out with the objectives of supplying to CP designers data collected insitu, in the actual environment in which the protected structure is deployed. Sensors arrays have been deployed at six different sites from 35 m to 900 m depth. The measurements are based on ...
ABSTRACT Hydrostatic pressure testing, or hydrotesting, of oilfield production and storage equipment requires that the damage done to equipment during testing is minimal. In this case study, the storage tanks at a large liquefied natural gas (LNG) terminal were to be hydrotested using the natural brackish ...
ABSTRACT: In a case that coating like heat shrinkable sheet (HSS) or cold tape is detached from buried pipeline surface, cathodic protection current can't penetrate into the pipeline surface enough to polarize cathodically due to the impervious characteristic of outer backing layer. Microbiologically ...
