A NEW DEPOSITIONAL MODEL AND SEQUENCE STRATIGRAPHIC INTERPRETATION FOR THE UPPER JURASSIC ARAB "D" RESERVOIR IN QATAR
(
Blackwell Publishing Ltd
, 2001 , Article)
Deposition of the Arab Formation on the Arabian Plate followed a eustatic sea-level high during the Oxfordian that deposited the open-marine shelfal carbonates of the Hanifa and Jubaila Formations. Oolite/peloidal shoals ...

(
Elsevier
, 2009 , Article)
The charge-transfer interactions between the electron donor 4,4′-trimethylenedipiperidine (TMDP) and the acceptors 2,3,5,6-tetrachloro-1,4-benzoquinone (chloranil), 2,4,4,6-tetrabromo-2,5-cyclohexadienone (TBCHD), ...
Reduction kinetics of ceria surface by hydrogen
(
Wiley Periodicals, Inc.
, 2004 , Article)
Powdered cerium dioxide (ceria, CeO2) as compressed, sintered pellets, of porosity 16.4% and density 5.99 g cm?3, were treated in hydrogen flow at 1 atm and various temperatures to effect reduction. The electrical conductivity ...
Theoretical study of laser light generation and color image formation: FA1:Cs+ and FA2:Li+ centers at the low coordination (100) and (110) surfaces of AgCl and AgBr
(
Wiley Periodicals, Inc.
, 2005 , Article)
The FA1:Cs+ and FA2:Li+ color centers at the low coordination (100) and (110) surfaces of AgCl and AgBr play important roles in laser light generation and color image formation. Double-well potentials at these surfaces are ...

(
Elsevier Ltd
, 2008 , Article)
Geological investigations of the Halul and the Shraouh islands, offshore Qatar, indicate that most of their calcareous rocks, which display abundant stromatolitic bedding, belong to the Infra-Cambrian Hormuz Series. ...
Bordetella pertussis risA, but not risS, is required for maximal expression of Bvg-repressed genes
(
American Society for Microbiology
, 2005 , Article)
Expression of virulence determinants by Bordetella pertussis, the primary etiological agent of whooping cough, is regulated by the BvgAS two-component regulatory system. The role of a second two-component regulatory system, ...
