Lidar measurements of the aerosol depolarization ratio provide highly reliable informations to discriminate between spherical and non-spherical particles in the atmosphere and they can help to distinguish between liquid and solid phase aerosols. These measurements can be performed by using a linearly polarized laser source and a hardware configuration of the receiving system including two chann...

The synthesis and properties of large spherical molecules and giant clusters is a fascinating field in contemporary chemistry, unifying all areas of organic/supramolecular, inorganic, and coordination chemistry as well as organometallic chemistry. Recent developments of low-valent group 13 metalloid clusters,1 chalcogeno-bridged copper, and silver clusters2 as well as giant polyoxomolybdates3 r...

Effective lubrication performance of metal-on-metal hip implants only requires optimum conformity within the main loaded area, while it is advantageous to increase the clearance in the equatorial region. Such a varying clearance can be achieved by using non-spherical bearing surfaces for either acetabular or femoral components. An elastohydrodynamic lubrication model of a novel metal-on-metal h...

in this paper, we give some characterizations for legendre spherical, legendre normal and legendre rectifying curves in the 3-dimensional sasakian space. furthermore, we show that legendre spherical curves are also legendre normal curves. in particular, we prove that the inverse of curvature of a legendre rectifying curve is a non-constant linear function of the arclength parameter.

This paper extends the image charge solvation model (ICSM) [J. Chem. Phys. 131, 154103 (2009)], a hybrid explicit/implicit method to treat electrostatic interactions in computer simulations of biomolecules formulated for spherical cavities, to prolate spheroidal and triaxial ellipsoidal cavities, designed to better accommodate non-spherical solutes in molecular dynamics (MD) simulations. In add...

A spherical parallel manipulator (also called an orientational parallel manipulator or rotational parallel manipulator) refers to a threedegree-of-freedom (3-DoF) parallel manipulator in which the moving platform undergoes a 3-DoF spherical motion or rotates about a fixed point. In this paper, we propose a new method for the type synthesis of non-overconstrained (isostatic) spherical parallel m...

conclusions b. subtilis entrapped in beads was able to preserve its viability and produce biosurfactants as secondary metabolites. therefore, this method could be applied as a continuous culture system of biosurfactant production. methods alginate and bacterial solutions were mixed by stirring to obtain a uniform mixture and added by drops into cacl2 solution to form spherical beads. the spheri...
