conclusions saddle nose reconstruction with bone graft in multiple facial fracture patients is a predictable method if surgical accesses to the region are carefully designed, considering the accompanying fractures. results there were 11 patients treated using this method. the male-to-female ratio was 7:5. one miniscrew with the lag technique was the preferred method for the fixation of the dors...

OBJECTIVE There is no definitive study comparing stress distribution around two versus three implants in implant-retained overdentures with different cantilever length. The purpose of this finite element study was to evaluate stress pattern around the implants of the 2 or 3 implant- supported mandibular overdenture with different cantilevered length. MATERIALS AND METHODS The models used in t...

OBJECTIVE The purpose of this study was to assess funnel type and pregnancy duration in women with previous spontaneous preterm birth and cervical length <25 mm. STUDY DESIGN We performed a secondary analysis of a multicenter randomized trial of cerclage. At the randomization scan that documented short cervix, the presence and type of funnel (U or V) were recorded. RESULTS One hundred forty...

Novel zipper varactors with the potential for achieving large tuning ranges have been fabricated and characterized. These varactors have a curved cantilever electrode that is actuated by a single pull-down electrode. The shape of the cantilever is designed such that its local stiffness is tailored to enable extended stable zipping. In a series-mounted varactor, the measured capacitance ratio wa...

We consider the effects of a velocity-independent friction force on cantilever damping. It is shown that this dissipation mechanism causes nonlinear effects in the cantilever vibrations. The size of the nonlinear-ity increases with decreasing cantilever velocity. Our analysis makes it possible to understand Stipe's et al. [1] experiments where an amplitude dependence of the cantilever eigenfreq...

Objective: To explore the inverted T-shaped flap nursing after breast-conserving surgery combined with reverse double V-shaped mastoconstriction suspension for breast cancer, and summarizes methods experience. Method: 5 patients who underwent and formed incision were selected from same medical group in Department of Breast Cancer Sun Yat-sen University’s Center from February 1, 2019 to Ap...

The processing of biologically important sounds depends on the analysis of their frequency content by the cochlea and the CNS. GABAergic inhibition in the inferior colliculus shapes frequency response areas in echolocating bats, but a similar role in nonspecialized mammals has been questioned. We used the powerful combination of iontophoresis with detailed analysis of frequency response areas t...

It is shown that the energy harvesting capabilities of a piezoelectric cantilever can be enhanced through coupling to a static magnetic field. A permanent magnet is fixed to the end of a piezoelectric cantilever, causing it to experience a non-linear force as it moves with respect to a stationary magnet. The magnetically coupled cantilever responds to vibration over a much broader frequency ran...

A working model has been developed which can be used to significantly increase the accuracy of cantilever deflection measurements using optical beam techniques (used in cantilever-based sensors and atomic force microscopes), while simultaneously simplifying their use. By using elementary geometric optics and standard vector analysis it is possible, without any fitted or adjustable parameters, t...

-For high frequency and VHF point-to-point communication, the V-antenna reflector and the V-shaped antenna array are useful because of high gain, low cost, easy manoeuvering and simple geometry. The theoretical analysis for the radiation characteristics of a plane, twodimensional, V-shaped antenna array have been presented taking into account the mutual inductive coupling effect among the radia...
