We exposed human peripheral lymphocytes in vitro to 0.3 and 1 Gy of 60Co gamma rays to evaluate whether the ability and sensitivity to detect chromosomal aberrations by chromosome painting is independent or not to the specific paint probes. To detect structural aberrations (translocations), we painted chromosome spreads simultaneously with two whole-chromosome libraries for chromosomes 1, 2, 3,...

Introduction: Mawrth Vallis, Mars, exhibits unique stratigraphy characterized by distinct phyllosili-cate units across an expansive region [1,2]. A potential analog for this site is the Painted Desert in Arizona, where striking profiles of clay and iron oxide units color the landscape [3]. Both sites contain multiple phyllosilicate units in similar stratigraphy across wide regions. We have acqu...

Standoff laser induced breakdown spectroscopy (LIBS) has previously been used to classify trace residues as either hazardous (explosives, biological, etc.) or benign. Correct classification can become more difficult depending on the surface/substrate underneath the residue due to variations in the laser-material interaction. In addition, classification can become problematic if the substrate ma...

Three typical kinds of building materials (painted drywall, ceiling tile, and carpet) have been tested to study the effects of environmental conditions (temperature, relative humidity, and air velocity) on the sorption of volatile organic compounds (VOCs) by building materials. It was found that the effects of environmental conditions on sorption were insignificant for the painted drywall due t...

Parthenogenesis, embryonic development of an unfertilized egg, was studied for many years in turkeys. In fact, as many as 49% of unfertilized Beltsville Small White turkey eggs develop embryos. However, no research exists on parthenogenesis in quail. The Chinese painted quail is a close relative of the more common Japanese quail and, unlike turkeys or chickens, the small Chinese painted quail r...
