متن کاملChanging paradigms in implant dentistry.
This review focuses on five paradigms of implant dentistry which have undergone considerable modifications in recent years. An attempt was made to select and include all the relevant citations of the past 10 years. These five paradigms document the debate in the clinical and scientific community and include the aspects of (1) smooth vs. rough implant surfaces, (2) submerged vs. non-submerged im...
متن کاملChanging challenges and paradigms.
Change comes as a surprise because things do not happen in a straight line. Concepts often evolve haphazardly, reacting to specific events. Assumptions are made but are not challenged, sometimes for political or social expedience. It has long been recognized that the dose makes the poison. Concepts of the relationship evolved from both events and the availability of exploratory tools. There are...
متن کاملChanging times and Paradigms
Colleagues at a large public university I recently visited are doing some excellent research on first-year engineering students—what attracted them to engineering, how they view engineering as a curriculum and career, how they feel about their first-year courses (it isn’t pretty!), their confidence levels before and after those courses, and why the ones who drop out do so. I sat in on one of th...
متن کاملRegulatory Paradigms for Modern Breeding
rapid advances. Breeders using rDNA techniques can properly think of this technique as traditional biotechnology. Within the past ten years, breeders have begun to use newer techniques [site-directed nuclease techniques (SDNs), RNAi, and synthetic biology] to create and to develop plants and animals with desired genetic traits. Traditional breeding, whether by farmers or by scientists, has been...
