This study uses elliptical Fourier analysis to quantify shape differences observed in the P(4) crown of Neandertals and anatomically modern humans. Previously, P(4) shape was assessed qualitatively, and results suggested marked differences between Neandertals and anatomically modern humans (Bailey [2002] New Anat. 269:148-156). The goal of this study was to investigate the P(4) shape in more de...

A multiple linear model was developed for individual tree crown width of Cunninghamia lanceolata (Lamb.) Hook in Fujian province, southeast China. Data were obtained from 55 sample plots of pure China-fir plantation stands. An Ordinary Linear Least Squares (OLS) regression was used to establish the crown width model. To adjust for correlations between observations from the same sample plots, we...

The title compound, C(18)H(26)N(2)O(5)P(2), was obtained accidently from the reaction between N,N-dimethyl-phospho-ramido-chloridic acid 4-methyl phenyl ester, NaNO(2) and 18-crown-6 in acetonitrile under reflux conditions. The asymmetric unit contains one half-mol-ecule, the complete mol-ecule being generated by crystallographic twofold symmetry, with the bridging O atom lying on the rotation ...

The present work reports a study of the structural, elastic, dynamical and thermodynamic properties of rock salt (RS) LiCl within density functional theory. It is found that the lattice constant and elastic constants are in very good agreement with the other calculations or experimental values. The phonon dispersion curve along several high symmetry lines at the Brillouin zone (BZ) is determine...

Achieving symmetry of the soft-tissue margins between anterior maxillary dental-implant restorations and adjacent teeth is a therapeutic challenge for both the implant surgeon and the restorative dentist. This article describes a modified procedure utilizing autogenous connective-tissue grafts to improve primarily buccal soft-tissue margins and secondarily inter-proximal tissues around tooth-bo...

The intensities of the myosin-based layer lines in the x-ray diffraction patterns from live resting frog skeletal muscles with full thick-thin filament overlap from which partial lattice sampling effects had been removed were analyzed to elucidate the configurations of myosin crossbridges around the thick filament backbone to nanometer resolution. The repeat of myosin binding protein C (C-prote...

In this paper, we will obtain first integral, integrating factor and λ-symmetry of third-order ODEs u ⃛=F(x,u,u ̇,u ̈). Also we compare Prelle -Singer (PS) method and λ-symmetry method for third-order differential equations.In this paper, we will obtain first integral, integrating factor and λ-symmetry of third-order ODEs u ⃛=F(x,u,u ̇,u ̈).

Short clinical crown affects appearance and retention of the restoration placed within aesthetic zone. Thereafter, Surgical lengthening procedure is done to increase length for restorative or reasons without breaching biologic width. Herewith, we present a case along with osseous reduction on maxillary anteriors in 25 years female patient referred our department which resulted harmonious symmet...
