The European green crab (Carcinus maenas) has a six-year life span and has persisted at low densities in Oregon and Washington coastal estuaries since the late 1990’s. After the arrival of a strong year class in 1998, significant recruitment to the Oregon and Washington populations occurred only in 2003, 2005,...
The volatile components of rye flour were isolated
by steam distillation and trapped in cold traps under
vacuum. After preliminary tests indicated the presence
of carbonyl compounds, the distillate was reacted with
2,4 dinitrophenylhydrazine to convert the carbonyl compounds
to their stable derivatives, 2,4 dinitrophenylhydrazones.
Three classes of monocarbonyls were...
The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. After the arrival of a strong year class in 1998, significant recruitment to the populations occurred only in 2003, 2005, 2006, 2010, 2015, 2016, 2017, 2018 and 2019. Warm winter water temperatures,...
European green crab, Carcinus maenas, trapped and collected in coastal Oregon and Washington coastal estuaries during the 2019. Data for individual crabs include: estuary, site, date of collection, sex, carapace width, weight, molt stage (color of abdomen), missing limbs, estimated year class, method of collection, and name of collector.

Generalized modal analysis techniques for the characterization and modeling of dissipationless planar waveguide structures and discontinuities encountered in microwave and optical integrated circuits, as well as of quantum waveguide structures and devices, are presented. The frequency-dependent transmission properties of the curved microstrip bend are derived by utilizing a second-order perturbation...
The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. After the arrival of a strong year class in 1998, significant recruitment to the populations occurred only in 2003, 2005, 2006, 2010, 2015, 2016, 2017 and 2018. Warm winter water temperatures, high...
Data on green crabs collected and trapped from Makah Bay to Coos Bay in 2018. Data included: Estuary, site, date, sex, carapace width, weight, molt state, estimated year class, missing limbs, collection method, collector and pheromone treatment.
The El Niño/Southern Oscillation (ENSO) affects millions of people via global teleconnections in the form of drought and torrential rainfall that impact agriculture and food production in many countries. Yet how ENSO will respond to a warming world is uncertain and a greatly debated topic. The Intergovernmental Panel on Climate...

The European green crab (Carcinus maenas) has persisted in Oregon and Washington coastal estuaries since the late 1990s. A strong year class arrived during the 1998 El Niño, but numbers decreased and remained below 1 per trap per day until the arrival of the 2015-2016 El Niño. Since then, numbers...
