Design of a Half/Full Subtractor on Quantum-Dot Cellular Automata

Abstract: Quantum-dot cellular automata (QCA) is a novel nanotechnology which promises molecular digital circuits with ultra-high clock frequencies, alternative solution to replace to replace the conventional CMOS technology which is reaching their physical limits. Despite a lot is still needed for the large scale utilization of the technology, there has been serious effort in digital design implementation in QCA. In this paper, a new architecture of Half and Full subtractor based on the QCA is proposed. The benefit of optimal FNZ universal gate is taken in demonstrating these arithmetic units, which has already designed based on the QCA. The design helps to reduce the complexity, then the conventional subtractors based on the QCA, in terms of covered area, count of the cells, and delay. The proposed subtractors are designed and simulated using QCA Designer tool version 2.0.3.

Uses of high copper amalgam alloys in dentistry

Abstract: A filling is the repair of a damaged or decayed tooth, restoring it back to its normal shape, appearance and function. Amalgam Restoration is an example of the material giving its name to the process. Amalgam fillings are made up of mercury, powdered silver and tin. They are mixed and packed into cavities in teeth where it hardens slowly and replaces the missing tooth substance. The high copper have become material of choice as compared to low copper alloys nowadays because of their improved mechanical properties, corrosion resistance, better marginal integrity and improved performance in clinical trial. The high copper amalgam was used as a restorative material. The application of high copper amalgam was found to be much more useful than low copper amalgam. High copper had much more strength, corrosion resistance, durability and resistance to tarnish as compared to low copper amalgams. No marked expansion or condensation was noted in the amalgam restoration after its setting after 24 hrs. By using the high copper alloy, the chances of creep were also minimized in the restored tooth. No discomfort or any kind of odd sensation in the tooth was noted after few days of amalgam restoration in the tooth.A filling is the repair of a damaged or decayed tooth, restoring it back to its normal shape, appearance and function.

Erupted compound odontoma: Report of a rare case and literature update

Abstract: Odontomas are the most common benign, slow growing, and nonaggressive odontogenic tumors of the jaws. These tumors of epithelial and mesenchymal origin are actually hamartomas or developmental anomalies composed of normal tooth structure, that is, enamel, dentin, cementum, and pulp tissue. These asymptomatic lesions are radiographically diagnosed during the second decade of life. These are often associated with tooth eruption disturbances and malocclusion. The present paper reports a case of erupted compound odontoma in a 21-year-old male patient, which caused displacement of the adjacent tooth.
