H = S v i S v i + 1 ) y y corresponds to what is called the XY chain. The hexagonal compound PrCl3 provides a good approximation to the 1-D XY chain. The structure of PrCl3 is illustrated in Figure 1. Nearest neighbor Pr ions form chains along the hexagonal axis. Each Pr ion has nine close Cl neighbors which form three equilateral triangles; one triangle lies in the plane perpendicular to the h...

Comparison theorems on resistance distances and Kirchhoff indices of the so-called S& T -isomer graphs are established. Then these results are applied to compare Kirchhoff indices of hexagonal chains, showing that the straight chain is the unique chain with maximum Kirchhoff index, whereas the minimum Kirchhoff index is achieved only when the hexagonal chain is an ‘‘all-kink’’ chain. © 2014 Els...

based on the {s+, i-} pathway, the concentration of surfactant and surface charge density of silanolate groups control the phase transition from lamellar, to hexagonal through cubic form. the high surface charge density of silanolate groups was observed for the lamellar phase. with decrease of molar concentration of surfactant on the gel, the yield of reaction decreases and the stability of mes...

The aim of this study is to determine preparations of cheeps from cactus fruits. Cactus (opuntiassp), cactaceae family is well adapted to arid and hot dry lands, where the plants have a marked capacity to withstand prolonged drought. Cactus fruit have many uses such as: food popular, in medicine, for water treatment, for consumer health and etc. Re cactus pear also cactus apple, prickly pear Ba...

The formation of dorsal-ventral polarity in Drosophila requires the asymmetric nuclear localization of the dorsal protein along the D/V axis. This process is regulated by the action of the dorsal group genes and cactus. We show that dorsal and cactus are both phosphoproteins that form a stable cytoplasmic complex, and that the cactus protein is stabilized by its interaction with dorsal. The dor...

The cactus of a pointed graph is a discrete tree associated with this graph. Similarly, with every pointed geodesic metric space E, one can associate an R-tree called the continuous cactus of E. We prove under general assumptions that the cactus of random planar maps distributed according to Boltzmann weights and conditioned to have a fixed large number of vertices converges in distribution to ...

Although lipid phases are routinely studied by X-ray diffraction, construction of their unit cell structures from the diffraction data is difficult except for the lamellar phases. This is due to the well-known phase problem of X-ray diffraction. Here we successfully applied the multiwavelength anomalous dispersion (MAD) method to solve the phase problem for an inverted hexagonal phase of a phos...

CACTUS is a hydrokinetic turbine performance code under development at Sandia National Laboratories (SNL). Details on it capabilities are given in [1]. CACTUS simulates arbitrary geometries, including crossflow and axial flow rotors. SNL added new capabilities to CACTUS and an outreach effort was begun to solicit interest among MHK researchers and developers who want to consider CACTUS for hydr...
