The large shallow eutrophic Lake Taihu in China has long suffered from eutrophication and toxic cyanobacterial blooms. Despite considerable efforts to divert effluents from the watershed, the cyanobacterial blooms still reoccur and persist throughout summer. To mitigate cyanobacterial bloom pollution risk, a large scale integrated monitoring and forecasting system was developed, and a series of...

Under low growth-irradiance and/or excessive nitrogen (N) fertilization, the roots of leafy vegetables could take up nitrate (NO3) faster than the plant can convert it to organic nitrogen compounds. NO3 is suspected to have carcinogenic effect in human when eaten in high quantity. In this study, lettuce plants were first grown in an aeroponics system with full nutrients (full NO3) under full su...

Flows of carbon and nitrogen in a natural phytoplankton assemblage from the plume of the Scheldt estuary were followed during and after a light-induced bloom by measuring changes in concentrations and stable isotope ratios in mesocosms after addition of 13C (as bicarbonate or glucose) and 15N (as ammonium or nitrate). Addition of 13C-bicarbonate showed a strong coupling between algal primary pr...

This paper presents a scalable mechanism, Fast Routing Table Recovery (FRTR), for detecting and correcting route inconsistencies between neighboring BGP routers. A periodic update approach, used by most routing protocols, is considered infeasible due to the large size of today’s global routing table. In FRTR neighboring routers periodically exchange Bloom filter digests of the routing state to ...

BACKGROUND The standard of care for full-thickness burns is tangential excision followed by skin autografting; however, the timing of excision and grafting is subject to debate. The authors compared early (2 days) versus delayed (14 days) excision and grafting in a porcine full-thickness burn model. METHODS Full-thickness burns (n = 12) were created on the backs of two anesthetized pigs and a...

Background and aims – Massive algae growth resulting in a phytoplankton bloom is very rare event the meromictic oligotrophic Lake Tanganyika. Such was observed north of lake September 2018. Phytoplankton species composition during this compared to documented 1955, 2011–2013. Meteorological observations suggest hydrodynamics could explain occurrence 2018 bloom.Material methods net samples were t...
