Extensive horizons of pyritic shale occur in Mid-Proterozoic sediments of the eastern Belt basin, Montana, U.S.A. These pyritic shales are of striped appearance. Laminated pyrite beds alternate with non-pyritic shale beds. Laminated pyrite beds have wavy-crinkly internal laminae and are interpreted as mineralized microbial mats. Pyrite is essentially the only sulfide mineral in these shales. Py...

AIM AND OBJECTIVE: To compare the palatal rugae pattern between dentulous males and females of different age groups among the Chennai population.The individuality of a palatal rugae as an aid for personal identification was an objective of this study. BACKGROUND: Palatal rugae are asymmetrical irregular elevations of dense connective tissues located on the anterior third of the palate extending...

Radically shifting personal experience of the visual image from virtual worlds like Second Life, from flat screens, cinema, and paper to physical forms, subverts the predominance of the digital realm. Living on the surface of the screen minimizes the tactility of materials and the resonance of memory and meaning embodied in objects. Digital 3D cinema, 3D television, and 3D cameras are precursor...

The Phytocreneae (Icacinaceae) are a tribe of scrambling shrubs and lianas presently distributed in tropical Africa, Madagascar, and Indo-Malesia. We describe the oldest known fossils of this tribe and provide the first recognition of this group in the Neotropical fossil record based on distinctive fruit remains. Palaeophytocrene piggae sp. nov., from the late Paleocene of western North America...

Phylogenetic analyses of 159 DNA sequences from the nuclear rDNA internal transcribed spacer regionwere conducted to evaluate the monophyly of the herbaceous, perennial genera of Apiaceae subfamily Apioideae endemic to North America (north of Mexico) and to determine the relationships of those elements that currently comprise Cymopterus within the group. The results of a previous phylogenetic s...

2014 We study the apparent biaxiality of a sample of a lamellar liquid crystal in homeotropic orientation and containing oriented defects. The biaxiality is calculated in the case of edge dislocations parallel to each other. We show also that in lyotropic liquid crystals, light scattering is very weak and does not obliterate the conoscopic image. We also make a comparison with the experimental ...

2014 Under heating, a hydrated egg lecithin multilamellar sample in a planar geometry (lamellae normal to the plates) shows a periodic striation instability, followed at higher heating by the socalled « ear-like » domains. We first demonstrate that a normal lamellae contraction under heating can result into a lamellar undulation instability in a planar sample, as well as in a homeotropic geomet...

A new Video Plankton Recorder (VPRII) has been developed for rapid surveys of plankton and seston in the size range of 100μm–1cm. The VPRII system includes: 1) a high-resolution digital camera (1Mpixel, 10-bits, 30Hz frame-rate), 2) a fast towfish capable of tow speeds up to 12 knots and 3-axis motion for automatic undulation and ship-wake avoidance, small diameter tow cable and winch for deplo...
