Multipolar spherical solutions to the three-dimensional steady vorticity equation are provided. These based on separation of radial and angular contributions in terms Bessel functions vector harmonics, respectively. In this set multipolar vortex solutions, Hicks–Moffatt swirling is categorized as a degree ${\ell }=1$ therefore dipole. This dipole geometry equivalent two-dimensional Lamb–Chaplyg...

The shells of various poly(dl-lactide)-b-poly(acrylic acid) (PDLLA-b-PAA) spherical micelles and poly(l-lactide)-b-poly(acrylic acid) (PLLA-b-PAA) cylindrical micelles were functionalized with mannose to yield glyco-nanoparticles (GNPs) with different shapes and dimensions. All of these GNPs were shown to have good biocompatibility (up to 1 mg/mL). Cellular uptake experiments using RAW 264.7 ha...

Spherical converging shock waves with incoming Mach number 1.18 are generated in a conical test chamber fitted to conventional square-section tube. A wave cutter is employed ensure proper transition from the square cylindrical straight pipe installed upstream of convergent section. The incident planar transformed into spherical by use an ellipsoidal membrane acting as gas lens separating two ga...

In this paper, we implement finite volume Weighted Essentially Non-Oscillatory (WENO) schemes in both cylindrical and spherical coordinate systems for the Euler equations with cylindrical or spherical symmetry. We analyze three different spatial discretizations: one that is shown to be high-order accurate but not conservative, one conservative but not high-order accurate, and one both high-orde...

Packed bed reactors have many applications in different industries such as chemical, petrochemical, and refinery industries. In this work, the effects of some parameters such as the shape and size of particles, bed size, and bed length on the hydrodynamics of the packed beds containing three spherical, cylindrical, and cubic particles types are investigated using CFD. The effect of the combinat...

A two-phase ow model for an acceleration-driven compressible uid mixing layer is applied to an initially planar/cylindrical/spherical uid connguration. A conservative form of the one-dimensional compressible equations is derived under the assumption that the uid concentration is continuous. With a hyperbolic conservation law for the concentration gradient, the model supports traveling discontin...

Recent coded aperture imaging systems have shown great success in scene reconstruction, extended depth-of-field and light field imaging. By far nearly all solutions are built on top of commodity cameras equipped with a single spherical lens. In this paper, we explore coded aperture solutions on a special non-centric lens called the crossedslit (XSlit) lens. An XSlit lens uses a relay of two ort...

OBJECTIVE To evaluate the accuracy of noncycloplegic refraction compared with cycloplegic refraction in diagnosing refractive error in primary school children in southern Thailand. MATERIAL AND METHOD This is a cross-sectional study. One hundred twenty children aged from 6-13 years who had visual acuity of 20/40 or worse in at least one eye were included. All the children underwent autorefrac...

The low Young's modulus of biological particles results in their large deformation against the AFM probe forces; therefore, it is necessary to study the contact mechanics of bioparticles in order to predict their mechanical behaviors. This paper specifically deals with the contact mechanics of DNA nanoparticles with spherical and cylindrical shapes during manipulation. In previous studies, ...
