Nitrogen cycling in a turbid, tidal estuary

, 2007
In this thesis I investigated nitrification, dissolved inorganic and organic nitrogen uptake, and the relative importance of nitrification and ammonium assimilation. I have also investigated exchange with marshes and sediments. Nitrification, oxidation of ammonium to nitrate is the first step for removal of nitrogen from a system. Evaluating a suitable

Variability of tidal constants in the Río de la Plata estuary associated to the natural cycles of the runoff

, 2014
We analyze the only long-term (47-years long) hourly tide-gauge record available for the Río de la Plata estuary for variability in the amplitude and phase of the dominant principal lunar semi-diurnal (M2) constituent. The tidal record was first filtered

Consumer diversity drives stronger predation in tropical marine communities

Ecography, EarlyView.
Biotic interactions are predicted to be stronger in the tropics compared to higher latitudes, contributing to observed patterns of global biodiversity. While increased consumer diversity and more complex food webs are expected in tropical communities, the trophic dynamics underlying strong regional effects of predation are not well understood.

Strength Degradation and Chloride Ion Diffusion Behavior of Concrete Under Simulated Marine Exposure

Journal of Marine Science and Engineering
Chloride-induced deterioration is a major threat to the durability of marine concrete structures, especially in tidal and submerged zones. This study simulated these environments by immersing C45 concrete specimens in NaCl solutions (5%, 10%, 15%) under ...

The impacts of climate change on estuarine ecosystems : a case study on the Eden estuary, Fife, Scotland

, 2013
The Eden Estuary is a small, coastal inlet situated in Fife between the Tay and Forth Estuaries on the east coast of Scotland. A multidisciplinary case study of the estuary was conducted over a three year period observing the dynamic responses of biotic

Bioinspired Crossmodal Tactile Sensory Nerve for High‐Accurate Object Recognition

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
An artificial crossmodal sensory neuron system (ACSNS) that combines a complementary memristor with high‐sensitivity pressure–temperature bimodal sensors, which integrate tactile perception, information storage, and neuromorphic computing. With the aid of machine learning, this ACSNS presents an improved accuracy of 96.67% in recognizing temperatures ...

Details on the transport of European eel larvae through the Strait of Gibraltar into the Mediterranean Sea

Scientific Reports
Numbers of European glass eels (Anguilla anguilla) monitored along the Atlantic and Mediterranean coasts of Europe currently serve as the main stock indicator in assessment of this critically endangered species. Spawning, however, takes place exclusively

Synergistic Regulation of Hierarchical Anode Interphase and Cathode Electronic Structure by a Fe(III) Complex for High‐Performance Aqueous Zinc‐Manganese Battery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The NGB additive can concurrently address anode and cathode issues during Zn‐Mn battery cycling by constructing a hierarchical interfacial layer on the anode surface to alleviate side reactions and modulate zinc deposition and by incorporating Fe3+ ions into the α‐MnO2 cathode to improve its structural stability and electrical conductivity.
