Some of the challenges of root coverage with connective tissue graft are donor site morbidity and patient discomfort from the surgical procedure, as well as poor patient cooperation in correcting and controlling precipitating and predisposing factors of gingival recession.Objective: This case report shows a coronal displacement technique with a sub
Natural gas from ultra-deep reservoirs has been a major contributor for reserves boost, deliverability construction, and profits growth in natural gas industry in China.As a significant strategic domain in the future development of upstream business, the high-quality development of ultra-deep gas resources has great significance for economic benefi
To overcome the dependence on sunlight of multi-spectral cameras, an active light source multi-spectral imaging system was designed and a preliminary experimental study was conducted at night without solar interference.The system includes an active light source and a multi-spectral camera.The active light source consists of four integrated LED (Lig
This study aims to illustrate the effect of the reciprocal relationship between the exchange rates and interest rates on the bond market by using the SVAR model for China during (2000 -2020), this is to analyze and measure the relationship between exchange rates and interest rates and showing their impact through changes in the bond index and monit
The excitation of Fast Magnetosonic (FMS) waves by a cylindrical array of parallel tethers carrying time-modulated current is discussed.The tethers would fly Car Coaster vertical in the equatorial plane, which is perpendicular to the geomagnetic field when its tilt is ignored, and would be stabilized by the gravity gradient.The tether array would r
