Displaced tripod zygomaticomaxillary complex (ZMC) fractures are generally treated with open reduction and 3-point rigid internal fixation at the frontozygomatic suture, zygomaticomaxillary buttress, and inferior orbital rim. However, a clinical dilemma still exists in the postoperative morbidities such as ectropion of the lower eyelid and palpability of the Ti-plate at the inferior orbital rim...

T he tripod concept has proved to be a valuable model in understanding nasal tip dynamics. Peter A. Adamson, MD, FRCSC, and colleagues propose the M-Arch Model, which expands the nasal tripod concept by considering the nasal tip tripod in its entirety as an arch. This novel model stresses the importance of the overall length of the medial, intermediate, and lateral crural segments as they form ...

Purpose The purpose of this paper is to identify and describe the drivers of trading company strategy that explain trading company success in international business. Design/methodology/approach The strategy tripod that results from combining the industry-, resourceand institution-based views, each of which proposes specific drivers of strategic success, was used as the framework for investigati...

My objectives were to (a) measure the size-dependent particle concentration and settling velocities with the use of newly developed instruments funded through this program. These instruments, LISST100 and LISST-ST employ the principles of multi-angle light scattering and a mathematical inversion of these measurements for estimating the particle concentration in 32 log-spaced (equi-phi) interval...

We present a reactive controller that is able to displace a legged robot along an arbitrary trajectory with a high degree of accuracy. We designed the different modules of our controller so that they can deal with arbitrary leg configurations. In this way, any leg movement necessary to overcome unexpected terrain irregularities can be correctly compensated by the controller, while still followi...

In this paper, a prototype of a LARM leg mechanism is proposed by using a tripod manipulator and its operation performance is investigated through lab experimental tests. In particular, an experimental layout is presented for investigating operational performance. A prescribed motion with an isosceles trapezoid trajectory is used for characterizing the system behavior. Experiment results are an...

PURPOSE To examine the impact of prolonged graphomotor tasks on tripod-pinch strength and on handwriting process and product measures of children with dysgraphia and typical peers. METHOD Participants were 51 children in third to fifth grades, divided into two groups: 23 children with dysgraphia and 28 typical peers, as determined by the Handwriting Proficiency Screening Questionnaire. The pr...

OBJECTIVE To examine changes in respiratory dynamics in patients with chronic obstructive pulmonary disease (COPD) sitting leaning forward with hands supported on the knees (tripod position), a posture frequently assumed by patients in respiratory distress. METHODS Spirometry, maximal inspiratory and expiratory pressures (MIP and MEP) generated at the mouth, and diaphragmatic excursion during...

Non-invasive dynamical measurements of 3D scapular motion can be performed easily by attachment of a 6 DOF electromagnetic receiver onto the skin above the acromion. To quantify the introduction of possible errors due to skin displacement, we assessed 3D scapular positions on n=8 subjects by both tripod and skin-fixed method. Error analysis included the variables method (tripod, skin-fixed simu...

OBJECTIVE The purpose of this research was to study how the speed and legibility of fourth-graders handwriting was affected by type of pencil grip on the Evaluation Tool of Children's Handwriting-Cursive. METHOD Ninety-five typically developing students and 6 students receiving special education services completed the Evaluation Tool of Children's Handwriting-Cursive (ETCH-C). Photographs wer...
