Filler and chemicals.

Filler rhinoplasty.

The nose is one of the most important cosmetic units of the face. Discreet variations in the nose shape lead to marked physiognomy changes. Many patients dissatisfied with the appearance of their nose seek cosmetic improvement as early as during adolescence. Similar to other facial structures, the nose is affected by the aging process. Typically, nose tip drop is observed, along with loss of su...

Nature's chemicals and synthetic chemicals: comparative toxicology.

The toxicology of synthetic chemicals is compared to that of natural chemicals, which represent the vast bulk of the chemicals to which humans are exposed. It is argued that animals have a broad array of inducible general defenses to combat the changing array of toxic chemicals in plant food (nature's pesticides) and that these defenses are effective against both natural and synthetic toxins. S...

English Filler Gap Constructions

In the tradition of transformational grammar, the term ‘(grammatical) construction’ has been a theoretical taboo at least since the 1980s. It was then that Chomsky argued that transformations like ‘passive’ and ‘raising’, common in earlier versions of transformational grammar, should be eliminated in favor of general conditions on structures that would allow a single operation – ‘Move NP’ – to ...

Effects of monomer composition and original filler content on filler loading in the resulting centrifuged composites.

This study examined the effects of monomer composition, original filler content, and application of centrifugal force on the resulting filler loading of composites. Either Bis-MPEPP or UDMA was mixed with TEGDMA at a molar ratio of 1 : 1. Silane-treated silica (14-20 wt%) was added to each mixture. After the mixtures were centrifuged and light-polymerized, rate of increase was determined as the...
