The purpose of this retrospective study was to analyze changes in the position condyles following mandibular setback surgery with manual guidance. included 28 patients prognathism who underwent using guidance a bioabsorbable mesh for fixation, and center condylar head were compared at three time points: before (T0), within 1 week after (T1), 6 months (T2). results showed significant lateral, an...

The present paper deals with notions from the field of complex analysis which have been adapted to fuzzy sets theory, namely, part dealing geometric function theory. Several differential subordinations are established regarding operator L?m, given by L?m:An?An, L?mf(z)=(1??)Rmf(z)+?Smf(z), where An={f?H(U),f(z)=z+an+1zn+1+…,z?U} is subclass normalized holomorphic functions and operators Rmf(z) ...

In this paper, we first construct a model for free surface flows that takes into account the air entrainment by a system of four partial differential equations. We derive it by taking averaged values of gas and fluid velocities on the cross surface flow in the Euler equations (incompressible for the fluid and compressible for the gas). The obtained system is conditionally hyperbolic. Then, we p...

The title compound, C3H5N3O8, was synthesized by reacting 2-nitro-propane-1,3-diol with acetyl nitrate. The mol-ecule is bisected by a crystallograpic mirror plane. In the crystal, the mol-ecules pack in a ribbon-like fashion along the c axis, with the central nitro groups pointing in the same direction. C-H⋯O contacts apparently provide some additional packing stabilization.

In the crystal structure of the title compound, C(9)H(11)BrO(2), mol-ecules are stacked parallel to the b-axis direction, forming double layers in which the molecules are arranged head-to-head, with the bromo-methyl groups pointing towards each other.

We derive analytical expressions for the solid angle subtended by a circular disc at a point source with cosine angular distribution (f(μ) = μ/π) under the sole condition that the disc lies in the half-space illuminated by the source (μ ≥ 0). The expressions are given with reference to two alternative coordinate systems (S and S’), S being such that the z axis is parallel to the symmetry axis o...

Burbank (1965) has recently discussed under the title Intrinsic and Systematic Multiple Diffraction the conditions giving rise to multiple diffraction for the single-crystal orienter and for the precession camera. He concludes that there are important differences between the two techniques. For the single-crystal orienter, multiple diffraction will always occur if the crystal is mounted with a ...

In highly anisotropic organic superconductor (TMTSF)2ClO4, superconducting (SC) phase coexists with metallic and spin-density wave phases in the form of domains. Using Maxwell-Garnett approximation (MGA), we calculate volume ratio estimate shape these embedded SC domains from resistivity data at various temperature anion disorder, controlled by cooling rate or annealing time (TMTSF)2ClO4 sample...
