3D Circuits are one of the most promising technologies for reducing wire lengths [1] and improving circuit power [2] and timing [3] for future high performance designs. On a 3D VLSI Circuit, tiers of active area are stacked, providing higher integration density, shrinking the distances between the cells and reducing wire lengths as a consequence. In order to take full benefit of the technology,...

PURPOSE Large changes in spectacle prescription can increase falls risk in older people. We investigated the effect of induced astigmatism (a common cause of distorted or blurred vision in older people) on locomotor stepping patterns to determine whether the orientation of astigmatic changes could have differential effects on gait safety when negotiating steps and stairs. METHODS 10 older adu...

BACKGROUND Many publications, including the instructions accompanying central venous catheters, state that it is negligent to site the catheter tip in the right atrium. If the catheter tip is above the carina on a post-procedure radiograph then it is generally accepted that the catheter lies outside the right atrium. It is also recommended that the catheter tip should lie in the long axis of th...

Background To ensure accurate implant placement, surgical guides are used to control the steps of placement surgery. Purpose Evaluation accuracy in long span edentulous area by novice clinicians according fully-guided (FG), pilot-guided (PG), and freehand (FH) protocols. Materials methods Maxillary models with four missing teeth from right first canine molar were produced 3-dimensional printing...

OBJECTIVES The purpose of this cone beam computed tomography (CBCT) study was to describe the facial bone changes around single implants for immediate placement and provisionalization following tooth extraction in the maxillary anterior. MATERIAL AND METHODS The data between 2008 and 2013 were collected retrospectively. Superimposed facio-palatal cross-sectional CBCT images for the implants w...

in this article, a multi-objective function for placement of distributed generation (dg) and capacitors with thetap setting of under load tap changer (ultc) transformer is introduced. most of the recent articles have paidless attention to dg, capacitor placement and ultc effects in the distribution network simultaneously. insimulations, a comparison between different modes was carried out with,...

The aim of the present case report was to demonstrate vertical gain in posterior resorbed mandible utilizing use an Allograft Customized Bone Block. presents a 66-year-old healthy female nonsmoker who lost her right mandibular molars long time ago. In past, she had implant placement, which failed due fracture implant. Due high risk nerve damage, left jaw and completely covered with bone. Since ...

BACKGROUND Anecdotal evidence suggests that a vertical small-needle injection method enters the caudal epidural space with comparable efficacy to cephalad-directed methods, with less intravascular injection. OBJECTIVES Assess the success rate of vertical caudal epidural injection using epidurography and the frequency of intravascular injection using a vertical small-needle approach. PATIENT...

Objectives The aim of present randomized controlled clinical trial was to clinically evaluate hard tissue changes after extraction socket preservation procedures compared to natural spontaneous healing. Material and Methods Thirty patients were enrolled in the present study and underwent single-tooth extraction in the premolar/molar areas. Ten sites were grafted with porcine-derived bone cove...
