Light-toned salty soils and coexisting Si-rich species discovered by the Mars Exploration Rover Spirit in Columbia Hills
(Journal of Geophysical Research, 2008-12-19)
Light-toned soils were exposed, through serendipitous excavations by Spirit Rover wheels, at eight locations in the Columbia Hills. Their occurrences were grouped into four types on the basis of geomorphic settings. At ...
Remembering the Air India disaster: Memorial and counter-memorial

The Number of Ternary Words Avoiding Abelian Cubes Grows Exponentially
(2004-06-19)
We show that the number of ternary words of length n avoiding abelian cubes grows
faster than r^n, where r = 2^{1/24}
Binary Words Containing Infinitely Many Overlaps
(The Electronic Journal of Combinatorics, 2006-09-22)
We characterize the squares occurring in infinite overlap-free binary words and construct various α power-free binary words containing infinitely many overlaps.
Vertex-transitive self-complementary uniform hypergraphs of prime order
(Discrete Mathematics, 2009-09)
For an integer n and a prime p, let n(p)=max{i:pidividesn}. In this paper, we present a construction for vertex-transitive self-complementary k-uniform hypergraphs of order n for each integer n such that pn(p)≡1(mod2ℓ+1) ...
Stability of hydrated minerals on Mars
(Geophysical Research Letters, 2007-10-20)
The validity of recent identification of various hydrated minerals (kieserite, gypsum, hexahydrite, nontronite, chamosite, and montmorillonite) on Mars was assessed by exposing these minerals to simulated Martian surface ...
Differential Enantioselective Transformation of Atropisomeric Polychlorinated Biphenyls by Multiple Bacterial Strains with Different Inducing Compounds
(American Society for Microbiology., 2002-11)
Enantioselective biotransformation of polychlorinated biphenyls
(PCBs) has been suggested from studies showing differential
occurrence of PCB enantiomers in environmental samples, including river and riparian biota and ...
Steinbach Public Transportation Study
(2006-01-01)
This document constitutes the final report for the Steinbach Transportation Project Steering
Committee (STPSC). This report includes a demographic profile of Steinbach; a literature review
dealing with many of the relevant ...
