Using Ir(iii) complexes as dopants in phosphorescent organic light-emitting diodes (PhOLEDs) is the most successful strategy to attain long-lasting and highly-performant electroluminescent devices. Whilst highly efficient blue PhOLEDs are accessible, their limited operational lifetimes still restraint their practical use in lighting and displays. These short lifetimes are directly related to th...

Within the seismological community, long-term networks of ocean bottom seismometers (OBSs) are being deployed increasingly for a year or more to monitor earthquakes. These geophysical studies are motivated by the goals of understanding both plate tectonics and the hazards from subduction zones. However, because OBSs typically record signals up to frequencies of ~25 Hz or higher, they also provi...

BLUE CARBON IN FRESHWATER / BRACKISH MARSHES ON THE BARRIER ISLANDS OF VIRGINIA: ABOVEGROUND NET PRIMARY PRODUCTIVITY AND CARBON POOLS Emily Caitlin Adams Old Dominion University, 2015 Director: Dr. Frank P. Day “Blue carbon” is a relatively new concept describing carbon distributed tidally and sequestered via net production within coastal ecosystems, including seagrass beds, mangrove forests, ...

C orporate strategy is heavily influenced by its military roots. The very language of strategy is imbued with military references – chief executive ‘‘officers’’ in ‘‘headquarters’’, ‘‘troops’’ on the ‘‘front lines.’’ Described this way, strategy is about confronting an opponent and fighting over a given piece of land that is both limited and constant. Traditionally, strategy focused on beating ...

Characterization of two genetically distinct groups of marine Synechococcus sp. strains shows that one, but not the other, increases its phycourobilin/phycoerythrobilin chromophore ratio when growing in blue light. This ability of at least some marine Synechococcus strains to chromatically adapt may help explain their greater abundance in particular ocean environments than cyanobacteria of the ...

The article analyses the key directions of Turkey’s foreign policy under presidency Recep Tayyip Erdogan. It examines concepts such as “ba-lance” in relations with Middle East and West, which Turkey is trying to achieve through development its economy international trade. also focuses on concept “security East”, reflects focus security concerns from terrorist groups border Syria Iraq. Researche...

In implementing the vision described in the 2000 Report of the Presidents Panel on Ocean Exploration, the National Oceanic and Atmospheric Administration (NOAA) Office of Ocean Exploration (OE) has sponsored pathfinding ocean exploration expeditions in 2001 and 2002. Emerging large and diverse data sets from these expeditions and future missions warrant a robust data management capability to pr...

Biorefinery is the ideal model to help marine industries apply green and blue economy principles towards a more sustainable, profitable, conscious ocean economy.

Stable isotopes of carbon and nitrogen were used to test the hypothesis that stomach content analysis has systematically overlooked the consumption of gelatinous zooplankton by pelagic mesopredators and apex predators. The results strongly supported a major role of gelatinous plankton in the diet of bluefin tuna (Thunnus thynnus), little tunny (Euthynnus alletteratus), spearfish (Tetrapturus be...

Ocean wave simulation has a wide range of applications in movies, video games and training systems. Wind force is the main energy resource for generating ocean waves, which are the result of the interaction between wind and the ocean surface. While numerous methods to handle simulating oceans and other fluid phenomena have undergone rapid development during the past years in the field of comput...
