The Transmandibular Distractor (TMD) is an intraoral expansion device for symphyseal widening by callus distraction. Its advantages include limited surgical exposure, skeletal anchorage, and expansion along the arch segment together with proportional and differential widening in the frontal plane.

M any metropolitan areas will require urban highway reconstruction in the coming years, with a potential for severe trafficd-isruption and associated accidents. This article discusses the results and recommendations of the Corridor Management Task Force Plan created to look into transportation measures, which, if implemented, could facilitate traffic flow on this and similar primary travel corr...

In the aim of assessing the potential of tributary widening with respect to river rehabilitation in fluvial systems, attention is focused on the effects of tributary widening on the morphodynamic processes of confluence zones. Systematic tests were performed in a confluence flume where the confluent channels are connected with an angle of 90° and the main channel is 0.50 m wide. Three different...

The road is one of the transportation infrastructures that have a role as connector between regions, and also contributes to strengthening growth economy, society, tourism, culture region. Today, tourism activity in Indonesia growing rapidly, marked by increasing number tourist areas being built, which Arak-Arak natural area Bondowoso Regency, East Java. Located hilly with an altitude 345 meter...

Complex terrain conditions of wind farms, the large weight and long size turbine equipment, high economic requirements transportation on roads, a shortage relevant standards codes lead to difficulty in road design route selection farms. In addition, frequent excavations landfills farm construction have seriously destroyed vegetation cover soil structure primary surface, resulting amount water l...

We study the variation of Lyapunov exponents of simple dynamical systems near attractor-widening and attractor-merging crises. The largest Lyapunov exponent has universal behaviour, showing abrupt variation as a function of the control parameter as the system passes through the crisis point, either in the value itself, in the case of the attractor-widening crisis, or in the slope, for attractor...

In this paper, we discuss how Artificial Intelligence (AI) techniques might be brought to bear in automatically recognizing “creative reasoning” in student e-discussions. An AI-based graph-matching algorithm was used to find instances of deepening and widening, interactional categories that provide evidence of, respectively, explicit argumentation and creative reasoning. A deepening occurs when...

Linear Relation Analysis [CH78,Hal79] is one of the first, but still one of the most powerful, abstract interpretations working in an infinite lattice. As such, it makes use of a widening operator to enforce the convergence of fixpoint computations. While the approximation due to widening can be arbitrarily refined by delaying the application of widening, the analysis quickly becomes too expens...

Diagnosis of pseudoaneurysm of the aorta or its main branches is a challenge in patients with blunt chest trauma. Computed tomography helps to demonstrate intrathoracic hemorrhage and suspected great vascular injury when a chest radiograph reveals widening of the mediastinum. Aortic angiography remains the gold standard in the determination of the site, and severity of vascular injury for defin...

Aortic dissection is rare in the pediatric and young adult population. We hereby present a case of a 17-year- old male patient, without any predisposing factors, who developed an aortic dissection. The initial presentation was acute abdominal pain with massive retroperitoneal hematoma. His clinical condition deteriorated rapidly, did not respond to surgical hemostasis, and died within 36 hours ...
