In shallow coastal systems where most of the seafloor lies within the photic zone, benthic photoautotrophy plays a key role in regulating nutrient cycling. In these systems, production of submerged vascular plants (seagrasses), macroalgae and benthic microalgae is high and typically exceeds that of phytoplankton (Borum and Sand Jensen 1996). Changes in the patterns of primary production as well...

The present study was designed to study the effect of different growing media (clay, composted leaves and sand + composted leaves (1: 1 v/v) and fertilizer rates of mineral NPK (19: 19: 19) at 0.0, 2.5, 5 g / plant and their combined effect on the vegetative growth, flowering qualities, bulbs production and chemical constituents of leaves of Amaryllis (Hippeastrum vittatum, Herb.) plants during...

We present the calculation of the Wt single-top production channel to nextto-leading order in QCD, interfaced with parton showers within the MC@NLO formalism. This channel provides a complementary way of investigating the properties of the Wtb vertex, with respect to the sand t-channels. We pay special attention to the separation of this process from top quark pair production.

Complex life cycles have evolved independently numerous times in marine animals as well as in disparate algae. Such life histories typically involve a dispersive immature stage followed by settlement and metamorphosis to an adult stage on the sea floor. One commonality among animals exhibiting transitions of this type is that their larvae pass through a 'precompetent' period in which they do no...

Gas from natural gas hydrate (NGH) is priced competitively with prices. Most marine NGH stored in low cementing strata, which easily cause sand production problems, restricting the commercial and environmental safety of NGH’s development. This study applied a numerical simulation on hydrate-bearing sediments’ (HBS) exploitation. The was carried out for different productions laboratory results s...
