The multi-pulse heteroclinic orbits with a Melnikov method and chaotic dynamics in a parametrically and externally excited thin plate are studied in this paper for the first time. The thin plate is subjected to transversal and in-plane excitations, simultaneously. The formulas of the thin plate are derived from the von Kármán equation and Galerkin’s method. The method of multiple scales is used...

Cobalt-doping a NiTi layered double hydroxide affords CoNiTi-LDH with smaller plate sizes and higher degree of order, which allows the band gap to shrink from 2.7 eV 2.4 eV. is active for both water oxidation reduction.

Open reduction and anatomic reduction can create better function for the temporomandibular joint, compared with closed treatment in mandible fracture surgery. Therefore, the double miniplate fixation technique via mini-retromandibular incision was used in order to make the most stable fixation when performing subcondylar fracture surgery. Those approaches provide good visualization of the subco...

BACKGROUND To determine relative fixation strengths of a single lateral locking plate, a double construct of a locking plate, and a tibial nail used in treatment of proximal tibial extra-articular fractures. METHODS Three groups of composite tibial synthetic bones consisting of 5 specimens per group were included: lateral plating (LP) using a locking compression plate-proximal lateral tibia (...

BACKGROUND Finite element analysis was used to compare fixation methods for double pelvic osteotomy (DPO). Using 3D scanning a stereolithography (stl) image was produced of a canine pelvis and this was subsequently refined in computer aided design (CAD). Using the CAD files, the images were imported in MSC Marc software to produce a working finite element (FE) model with 3 dimensional tetrahedr...

The problem of a pulse excitation in an acoustic half-space with flexible wall described by thin plate equation is studied. solution written as double Fourier integral. A novel technique estimation this integral developed. surface integration deformed such way that the integrand exponentially small everywhere except neighbourhoods several ‘special points’ provide field components. Special atten...

In this paper we report a feasibility study of the gamma ray transmission imaging using a double gap resistive plate chamber. The detector consists of two layers of 2 mm resistive plate chamber (RPC) gaps with two-dimensional read-out strips of 10 mm pitch. Gamma ray transmission images for objects inside a cabinet, using a 10 mCi 137 Cs isotope, were obtained with a pixel resolution of 5 Â 5 m...

Langmuir's disjoining pressure between two flat, charged planes was calculated analytically for strongly overlapping double layers in the limit of zero electric field between the planes. The resulting repulsion has a long-range algebraic decay that stems from the thermodynamic equilibrium between homogeneously distributed interplate ions and ions in the surrounding electrolyte reservoir. Togeth...

We present a rare clinical case of a 90-year-old female who sustained a proximal femoral neck fracture following long-standing hip arthrodesis. Since the fracture occurred relatively proximally and involved the pelvis, double-plate fixation was chosen to achieve rigid fixation. The reconstruction plate was placed at the posterior and anterior columns individually through single vertical incisio...

To extend soft x-ray microscopy to a resolution of order 10 nm or better, we developed a new nanofabrication process for Fresnel zone plate lenses. The new process, based on the double patterning technique, has enabled us to fabricate high quality gold zone plates with 12 nm outer zones. Testing of the zone plate with the full-field transmission x-ray microscope, XM-1, in Berkeley, showed that ...
