Potentially important contributors to the topography and tectonics of multi-ring impact basins are the thermal contraction and thermal stress that accompany the loss of heat emplaced during basin formation. Heat converted from impact kinetic energy and contributed from the uplift of isotherms during cavity collapse are important components in the energy budget of a newly-formed basin. That the ...

Water column profiles of S2O and SO were obtained in January and May 2004 in the eastern portion of the 22 22 3 3 Cariaco Basin (108309N 648409W). Mean concentrations in the chemocline (250 to 450 m) decreased from 2.3 6 1.1 mmol L21 S2O in January to 1.4 6 0.3 mmol L21 S2O in May and from 4.8 6 2.9 mmol L 21 SO in 22 22 22 3 3 3 January to 2.7 6 0.7 mmol L21 SO in May. Integrated over this sam...

osteological features are important to study the taxonomy and phylogenetic relationship of fishes. since there is no information is available about osteological features of squalius orientalis , therefore this study was aimed to provide a detailed description of the osteological features of this species from the urmia lake basin of iran and comparing it with population of s. orientalis from the...

One hundred years ago this week the war poet David Jones was wounded on the Somme. Unlike other war poets it took over 20 years for the horrors he had witnessed to work their way out into his writing. This workshop examines the cognitive processes involved (a) when poets re-render past visual experience as words, and (b) when readers of those words reconstruct the original emotions for themselv...

Palladium-catalysed dearomatisation reactions allow access to a previously unknown class of indoloindole heterocycle: 5,10b-dihydroindolo[2,3-b]indoles. The highly reactive nature of these compounds is demonstrated by their facile reactions with water and with hydride, alkyl, aryl and allyl-based organometallic nucleophiles.

Whereas the application of atom-transfer radical cyclization reactions (ATRC reactions) to the synthesis of g-butyrolactams and g-butyrolactones is now reasonably well established, the same cannot be said of this approach to the synthesis of medium-sized rings. Previously we had shown that the trichloroacetate 1 (Scheme 1) undergoes sequential 5-exo, 6-exo ATRC reactions to provide rapid access...

For their work on the development of the modern cochlear implant, which bestows hearing to individuals with profound deafness, Ingeborg Hochmair, Graeme Clark, and Blake Wilson are the 2013 recipients of the Lasker∼DeBakey Clinical Medical Research Award.

sarygamesh basin one of the bulhary chay tributary take place in moghan plain, northeastern azarbyjan area in iran and south edge of kora- araz zone. aims of this research are study specificities and geomorphic evolution of sarygamesh basin, survey rivers work on structure and geologic formation, and corresponding hydrographic with earth structure. toward above aim is used to litologic, structu...
