Cosmetic procedures involving gingival reconstruction have become an integral part of current periodontal practice.The ability to cover unsightly exposed, sensitive roots and recontour soft tissue recessions have added an esthetic angle to the traditional concept of biological and functional periodontal health.The recession of the gingiva, either l
Migrants and Urban Rights: Politics of Xenophobia in South African Cities
In recent years there has been some critical intellectual reflections about here who has rights to the city, and how such rights are realised.As the rights based discourse gains momentum, groups that have been previously excluded from participating in the social, economic and political life of the city, for example, migrants, are becoming more asse
Long-Term Stability of Betavoltaic Battery Model and Prototype Based on Tritium/C-Silicon PN Junction Devices
The quantitative interpretation here of remaining oil saturation has a great significance for improving oil production and guiding the follow-up development of oil fields.The characteristic gamma rays are recorded to determine the remaining oil saturation, which is from the interaction of high energy neutron emitted by the pulsed neutron logging to
Experimental Research for Measuring Friction Forces from Piston Sealing at the Hydraulic Cylinders
The article presents some aspects of developing, within INOE 2000-IHP, of an experimental research on the determination of frictional forces that occur in the mobile sealings of the pistons, between the piston sealings and the inner liner of hydraulic cylinders.In the first part of the here paper, are presented some specific elements of the experim
