Abstract Introduction This study included 37 children who were treated by reconstruction of the temporomandibular joint (TMJ) by chondro-osseous graft from the iliac crest. The role of granular mesenchyme stem cells of the graft is to simulate normal condyle for continuous growth; it is also involved in repair and remodelling of the condyle, as shown by experimental studies conducted on rabbits...

The electronic conductance at zero temperature through a quantum wire with side-connected asymmetric quantum ring (as a scatter system) is theoretically studied using the non-interacting Hamiltonian Anderson tunneling method. In this paper we concentrate on the configuration of the quantum dot rings. We show that the asymmetric structure of QD-scatter system strongly influences the amplitude an...

In this article various pipes used for transporting of gas are introduced and pros and cons of each one are elucidated. The pipes are categorized in three different subgroups including metallic, polymeric and metallic-wire reinforced polymeric pipes. Metallic-wire reinforced polymeric pipes are nominated as the best option for usage in high pressure pipelines transporting natural gas. As a resu...

Introduction: The study was conducted to assess the stress and displacement effects of a mini-implant supported k-loop on maxillary dentition for distalization with 3-dimensional (3D) finite element analysis. Materials Methods: A 3D model maxilla all teeth, periodontal ligament, bone, mini-implants, brackets, archwire used in this study. analytic like wire, K-loop, mini-implants developed using...

While transcranial ultrasound imaging is a promising diagnostic modality, it still hindered due to phase aberration and multiple scattering caused by the skull. In this paper, we compare near-field phase-screen modeling (PS) geometry-based correction technique (GB) when an ultrafast sequence (five plane waves tilted from −15 +15 degrees in cutaneous tissue layer) used for data acquisition. With...

To evaluate the efficacy and safety of percutaneous K-wire leverage (PKWL) reduction and closed intramedullary pinning (CIMP) for the treatment of pediatric radial neck fractures. From June 2010 to December 2013, a total of 50 children with Judet III and IV radial neck fractures were treated at our hospital. Manual closed reduction was first attempted to reduce the radial neck fractures. Upon s...

background: the aim of this study was to evaluate the response of common sized fiber-reinforced composites (frcs) to different deflections due to bending forces and comparing it with stainless steel (ss) wires. materials and methods: in this experimental study, two frc groups with 0.75 mm and 1.2 mm diameters (everstick ortho, stick tech, finland) and three ss groups with 0.016 × 0.022 inch, 0....

this paper presents a new method called vespiary regular hexagonal (vrh) model to calculate parasitic capacitance between conductor wire filaments of one turn of a coil and between conductor wires filament and liner and also total capacitance of n-turns having single-layers, multi-conductor wire filaments of the helix magneto cumulative generator (mcg) coil. the presented method is an analytica...

Background: The purpose of this study was to evaluate the treatment outcomes of perilunate dislocations (PLDs) andtransscaphoid perilunate fracture dislocations (TSPLDs) treated with operative volar approach without ligament repairor reconstruction.Methods: A total of seven patients (10 hands) were studied during 2017-2018. We fixed scaphoid fractures thorougha volar app...
