Antibacterial Silica as Fillers for Denta
Silica nanoparticles with nanopores were used to incorporate antimicrobial agents, like silver nanopart cles or chlorhexidine. By the functionaliz ticles with different organosilanes a controlled d lease is possible. A stimuli-response system react to acidic conditions as caused by an infection and release the drugs only when necessary. could be incorporated into dental composite materials to p...

Young children often insert 'fillers' in their first multiwordutterances: vocalizations that do not correspond to conventional words. For instance, it is hard to determine the meaning of the syllables [m] and [∂] in utterance (1). So far, fillers have been investigated in French (i.a.

متن کاملFillers as signs of distributional learning.
A longitudinal analysis is presented of the fillers of a Dutch-speaking child between 1.10 and 2.7. Our analysis corroborates familiar regularities reported in the literature: most fillers resemble articles in shape and distribution, and are affected by rhythmic and positional constraints. A novel finding is the impact of the lexical environment: particular function words act as 'anchor' words ...
متن کاملTracking zoonotic pathogens using blood-sucking flies as 'flying syringes'
About 60% of emerging infectious diseases in humans are of zoonotic origin. Their increasing number requires the development of new methods for early detection and monitoring of infectious agents in wildlife. Here, we investigated whether blood meals from hematophagous flies could be used to identify the infectious agents circulating in wild vertebrates. To this aim, 1230 blood-engorged flies w...
