Discussion: Prosthodontic rehabilitation of patients with maxillectomy is a challenge as it involves restoring speech, deglutition, mastication and respiration. This clinical report describes a comprehensive prosthodontic management of a young girl treated for a subtotal maxillectomy due to intraosseous mucoepidermoid carcinoma. The prosthodontic management that was carried out right from the s...

With the exception, perhaps, of the tract of country lying at the base of the Himalaya Mountains known as the Terai, or the special region of malaria, the most unhealthy part of Bengal is the triangular piece of country which lies in the hollow, which is bounded by the high banks of the Rivers Ganges and Madhimati on the north and east, the elevated laterite soil districts of the Sonthal Pargan...

What is the largest cube or sphere that a given rectangular piece of paper can wrap? This natural problem, which has plagued giftwrappers everywhere, remains very much unsolved. Here we introduce new upper and lower bounds and consolidate previous results. Though these bounds rarely match, our results significantly reduce the gap.

Basic assumption and accuracy of complex permittivity measurement by perturbation technique are proposed to be verified by FDTD simulation of experimental cavity with QuickWave-3D. Determination of dielectric constant and loss factor of a piece of wet movie-film in rectangular resonator is shown to be very sensitive to film position and approved to be valid for low contents of water.

There has been recent interest in novel human-machine collaborative control laws, called “virtual fixtures,” which provide operator assistance for telemanipulation tasks. A forbidden-region virtual fixture is a constraint, implemented in software, that seeks to prevent the slave manipulator of a master/slave telemanipulation system from entering into a forbidden region of the workspace. In this...

The rapid development of manufacturing in recent years has led to a significant expansion the technological capabilities modern metal-cutting equipment. Therefore, approach intensifying production requires an advanced fixture design. Design and manufacture flexible fixtures capable machining similar shapes sizes complex geometry parts reduce setup time. article aims design for such as one-piece...

This work studied the effect of additions of carbon dioxide to argon shielding gas on the weld shape and microstructure of ST14 steel in pulsed Nd: YAG laser welding. By additions of carbon dioxide up to 15%,the weld area and depth/width ratio decreases while rising of carbon dioxide up to 25% causes increasing of weld area and depth/width ratio. It is observed that the weld metal microstructur...
