the most difficult maxillary teeth for endodontic treatment are the maxillary first molars (mfm) due to their complex root canal anatomy. the presence of two roots and c-shaped canals in mfms has been reported in rare cases. the present case reports root canal treatment of mfm with two roots, where the palatal and buccal roots were joined together in a c-shaped configuration .

Figure 1. PILOT telescope, enclosure and tower INTRODUCTION PILOT (The Pathfinder for an International Large Optical Telescope) is a 2.4m optical/infrared telescope, proposed for Dome C on the Antarctic Plateau, with target first light at the end of 2012.

numerical study of double-diffusive natural convective heat transfer in a curved cavity filledwith a porous medium has been carried out in the current study. polar system has beenselected as coordinate system. as a result, all equations have been discredited in r and θdirections. brinkmann extended darcy model has been utilized to express fluid flow inporous matrix in the enclosure. smaller and...

Enclosure methods are a class of computer-aided proofs used in analysis. They are used increasingly to solve open problems in mathematics. The proposed project will use enclosure methods to address two open statistical decision problems: 1. rigorous parameter estimation in a chaotic statistical experiment, and 2. rigorous point estimation and exact posterior sampling in phylogenetics. To addres...

Natural convection is intensively explored, especially in a valley-shaped trapezoidal enclosure, because of its broad presence both technical settings and nature. This study deals with cavity, which initially filled linearly stratified air. Although the sidewalls remain adiabatic, bottom wall heated, top cooled. For fluid (air), temperature adjacent to walls same as that walls. cavity simulated...
