The approach to toothpick ingestion and its complications should not be underestimated. The surgeon should be prepared for life-threatening situations such as major vascular involvement, as well as highly specialized and technically challenging procedures, when the hepatic hilum is involved for instance. Referral to tertiary centers is sometimes mandatory.

when very large floating structure) vlfs (is heavily loaded in the central portion, the difference deflection between its central section and its corners would increase. one cost effective solution for reducing the differential deflection is gill cell. gill cells are compartments in the vlfs that the buoyancy forces are eliminated at their locations. in this study, for examine the gill cells be...

conclusions there is clinical utility in knowing the relative deflection of various needle tips. when a procedure requires a needle to be steered around obstacles, or along non-collinear targets, the predictable and large amount of deflection obtained through use of a beveled spinal needle may prove beneficial. materials and methods six needles commonly used in spinal procedures (quincke, short...

Flexure mechanisms are a designer’s delight. Except for the limits of elasticity, flexures present few other boundaries as far as applications are concerned. Flexures have been used as bearings to provide smooth and guided motion. For example in precision motion stages; as springs to provide preload, for example in the brushes of a DC motor or a camera lens cap etc. Flexural joints are widely u...

OBJECTIVE The aim of this study was to evaluate whether vertical facial patterns influence maximal occlusal force (MOF), masticatory muscle electromyographic (EMG) activity, and medial mandibular flexure (MMF). MATERIAL AND METHODS Seventy-eight dentate subjects were divided into 3 groups by Ricketts's analysis: brachyfacial, mesofacial and dolychofacial. Maximum occlusal force in the molar r...

Primary colonic adenocarcinoma and synchronous rectal carcinoids are rare tumors. Whenever a synchronous tumor with a nonmetastatic carcinoid component is encountered, its prognosis is determined by the associate malignancy. The discovery of an asymptomatic gastrointestinal carcinoid during the operative treatment of another malignancy will usually only require resection without additional trea...

This paper presents a new and comprehensive method for modeling robots having highly flexible members such as flexure joints. An accurate model of large deformation bending is important for precisely describing the configuration of the flexible member. Additionally, the accuracy of the Jacobian and Hessian of the forward kinematics are critically important at large angles for predicting the def...

Unlike well-investigated polymer-based soft actuators such as gel, Ionic Polymer-Metal Composite, conducting polymer, a CFRP-based polymeric laminate possesses quite distinguished properties. It was previously reported that a CFRP-PVC laminate exhibited two-way deflection in accordance with environmental temperature, but it could not exhibit symmetric deflection because of its asymmetric struct...

OBJECTIVES The aim of this study was to assess and compare the characteristics of commonly used initial archwires by their load deflection graphs. MATERIALS AND METHODS This study tested three wire designs namely copper nickel titanium (CNT), nickel titanium (NiTi), and multi-strand NiTi (MSNT) archwires engaged in passive self-ligating (PSL) brackets, active self-ligating (ASL) brackets or c...
