Catalyst selective and regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates: synthetic and computational studies

Creator:: Gould, Eoin, Walden, Daniel M., Kasten, Kevin, Johnston, Ryne C., Wu, Jiufeng, Slawin, Alexandra M., Mustard, Thomas J. L., Johnston, Brittany, Davies, Tony, Cheong, Paul Ha-Yeon, and Smith, Andrew D.
Abstract:: The regiodivergent O- to C- or N-carboxyl transfer of pyrazolyl carbonates is described, with DMAP giving preferential N-carboxylation and triazolinylidenes promoting selective C-carboxylation (both with up to >99 : 1 regioselectivity). An enantioselective O- to C-carboxyl variant using NHC catalysis is demonstrated (up to 92% ee), while mechanistic and DFT studies outline...

Discoclavata dominicana n. gen., n. sp., (Coleoptera: Bostrichidae) and Lissantauga epicrana n. gen., n. sp. (Coleoptera: Ecumenidae) in Dominican amber

Creator:: Poinar, George, Jr.
Abstract:: A new genus and species of bostrichid, Discoclavata dominicana n. gen., n. sp., (Coleoptera: Bostrichidae) and a new genus and species of eucnemid, Lissantauga epicrana n. gen., n. sp. (Coleoptera: Eucnemidae) are described from Dominican amber. Diagnostic characters of Discoclavata dominicana include an extended body, strongly hypognathous head, asparate dorsal...

Tree mortality based fire severity classification for forest inventories: A Pacific Northwest national forests example

Creator:: Whittier, Thomas R. and Gray, Andrew N.
Abstract:: Determining how the frequency, severity, and extent of forest fires are changing in response to changes in management and climate is a key concern in many regions where fire is an important natural disturbance. In the USA the only national-scale fire severity classification uses satellite image change-detection to produce maps...

Seasonal cycles of currents, temperatures, winds, and sea level over the northeast pacific continental shelf: 35°N to 48°N

Creator:: Strub, P. Ted, Allen, John S., Huyer, Adriana, 1945-, Smith, Robert L. (Robert Lloyd), 1935-, and Beardsley, R. C.
Abstract:: Seasonal cycles of coastal wind stress, adjusted sea level (ASL), shelf currents, and water temperatures off the west coast of North America (35°N to 48°N) are estimated by fitting annual and semiannual harmonics to data from 1981-1983. Longer records (9-34 years) of monthly ASL indicate that these two harmonics adequately...

Tripius gyraloura n. sp. (Aphelenchoidea: Sphaerulariidae) parasitic in the gall midge Lasioptera donacis Coutin (Diptera: Cecidomyiidae)

Creator:: Poinar, George, Jr. and Thomas, Donald B.
Abstract:: A new nematode, Tripius gyraloura n. sp., is described from the arundo gall midge, Lasioptera donacis Coutin (Diptera: Cecidomyiidae). This gall midge is being considered as a biological control agent for use in North America against the introduced giant reed Arundo donax (L.) (Poaceae: Cyperales). Thus the present study was...

Patterns of mortality in an old-growth mixed-forest of the southern Sierra Nevada, California

Creator:: Smith, Thomas F., Rizzo, David M., and North, Malcolm
Abstract:: Mortality patterns in an old-growth, mixed-conifer forest, in the absence of wildfire, were investigated at the Teakettle Experimental Forest from 2000 to 2002. We tested the hypothesis that after a century of fire suppression, pathogen- and insect-associated mortality (between episodic droughts) would be significantly greater on ingrowth trees (i.e., smaller-diameter,...

The Electrochemical Synthesis of the Graphite Intercalation Compounds Containing Tetra-n-alkylammonium Cations

Creator:: Sirisaksoontorn, Weekit and Lerner, Michael M.
Abstract:: The electrochemical intercalation of tetra-n-alkylammonium (TAA) cations into graphite is investigated using galvanostatic reduction and cyclic voltammetry in TAABr/ dimethylsulfoxide (DMSO) electrolytes. Structural and compositional analyzes by X-ray diffraction, thermogravimetric and elemental analyzes show that stable graphite intercalation compounds (GICs) are formed with highly-flattened TAA cation bilayers for (C₅H₁₁)₄N⁺, (C₆H₁₃)₄N⁺,...

Minysporops dominicanus gen. n., sp. n. (Hemiptera: Pentatomoidea: Megarididae), a megaridid in Dominican amber

Creator:: Poinar, George, Jr. and Heiss, Ernst
Abstract:: A new genus and species of megaridid, Minysporops dominicanus gen. n., sp. n. (Hemiptera: Megarididae), is described from Dominican amber. Diagnostic characters include: Minute (under 2.00 mm), glabrous, nearly round body; declivitous flat-topped head; eyes constricted near middle, with dorsal eye shields; ocelli ovoid-elliptical; antennae 4-segmented, setose; rostrum 4- segmented;...

Thomas Hobbes and the Duke of Newcastle: A Study in the Mutuality of Patronage before the Establishment of the Royal Society

Creator:: Sarasohn, Lisa T.
Abstract:: This study shows how patronage framed and fashioned the careers of Thomas Hobbes and his patron William Cavendish, the earl of Newcastle. Newcastle's protection allowed Hobbes to articulate heterodox ideas without immediate fear of reprisal. It also enabled him to solidify his status as a gentleman and the intellectual equal...
