On certain estimates for marcinkiewicz integrals and extrapolation
(
Universidad de Barcelona
, 2009 , Article)
We obtain Lp estimates for parametric Marcinkiewicz integrals associated to polynomial mappings and with rough kernels on the unit sphere as well as on the radial direction. These estimates will allow us to use an extrapolation ...
A new depositional model and sequence stratigraphic interpretation for the upper Jurassic Arab "D" reservoir in Qatar
(
Wiley online Library
, 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 ...
Formation of a cold antihydrogen beam in AEGIS for gravity measurements
(
AIP Publishing
, 2008 , Article)
The formation of the antihydrogen beam in the AEGIS experiment through the use of inhomogeneous electric fields is discussed and simulation results including the geometry of the apparatus and realistic hypothesis about the ...
Phylogenetic analyses of peanut resistance gene candidates and screening of different genotypes for polymorphic markers
(
Elsevier
, 2009 , Article)
The nucleotide-binding-site-leucine-rich-repeat (NBS–LRR)-encoding gene family has attracted much research interest because approximately 75% of the plant disease resistance genes that have been cloned to date are from ...

The basis number of the strong product of paths and cycles with bipartite graphs
(
Central Missouri State University
, 2007 , Article)
The basis number of a graph G is defined to be the least integer d such that there is a basis B of the cycle space of G such that each edge of G is contained in at most d members of B. MacLane [13] proved that a graph G ...
Preliminary Survey on Parasites Infecting Some Amphibian and Reptilian Species from United Arab Emirates and Qatar
(
Qatar University
