Progress in adhesive technologies has made possible to perform more conservative restoration techniques. Bonded porcelain veneers have been widely used to address aesthetic dental problems for more than 3 decades1,2. Aesthetic parameter plays an important role when deciding the treatment choice of a patient with diastema. Development of the adhesive materials allows the dentist to construct mor...

 Image restoration is an essential preprocessing step for many image analysis applications. In any image restoration techniques, keeping structure of the image unchanged is very important. Such structure in an image often corresponds to the region discontinuities and edges. The techniques based on partial differential equations, such as the heat equations, are receiving considerable attention i...

The main challenge to restoration in Iceland is vast areas of severely degraded land that has limited resource retention and limited ecosystem functioning. These are often hostile environments for plant establishment and survival, due to unstable surfaces that are prone to intensive cryoturbation and erosion by wind and have limited water-holding capacity. Most of the degraded rangelands are op...

An example of this capacity is phoneme restoration, in which part of a word is completely replaced by noise, yet listeners report hearing the whole word. The neurological basis for this unconscious fill-in phenomenon is unknown, despite being a fundamental characte...
