The polymer-filler interaction of a dental composite was examined by dielectric measurements to determine how a non-compatible inorganic phase modifies the molecular behaviour of the polymer chains and how modification of this phase by silanation can affect these molecular behaviours. Urethane dimethacrylate (UDMA) monomer and zirconia-silica (ZS) powder were used as organic and inorganic phase...

INTRODUCTION Polyacrylamide hydrogel has been considered a safe and biocompatible soft tissue filler, and it has been widely used in cosmetic procedures. However, recent studies have revealed some complications with polyacrylamide filler injections. CASE REPORT We present the case of foreign-body granulomas of the glabella, which subsequently formed an infectious ulcer 3 years after a polyacr...

The combined use of a highly magnetic filler (mumetal) in low proportion and a highly conductive filler in high proportion in a polymer matrix provides a composite material that is more effective for electromagnetic interference shielding than the use of a highly magnetic filler alone or the use of a highly conductive filler alone. Mumetal is effective (due to absorption) when it is in a compos...

In this paper, I argue that the retrieval of filler-phrases in syntactic filler-gap dependencies is facilitated by encoding more information in the filler-phrase. Three self-paced reading experiments provide the evidence for this memory facilitation hypothesis: reading times decrease when more explicit whphrases and indefinites occur as fillers in three different syntactic constructions. Crucia...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Effect of TiO2 and ZrO2 filler on mechanical properties of the epoxy polymer has been investigated experimentally. TiO2 and ZrO2 filler epoxy composites are fabricated by hand layup technique in a mold and cured under light pressure at room tempera...

Filled pauses are ubiquitous in everyday speech. I investigated whether linguistic complexity of upcoming phrases affects filler rate at phrase boundaries in presentation speeches in Japanese. Filler rate at phrase boundaries increased monotonically with complexity of the following phrases. However, when the following phrase was composed of more than 11 Bunsetsu-phrases, the filler rate did not...

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...

Superior sulcus filler injection is a nonsurgical method to rejuvenate the upper face. Blindness and stroke are devastating complications of facial filler injection. This study describes an injection technique that minimizes the risk of blindness and includes a case study demonstrating the cosmetic benefits of this procedure. To avoid retrograde injection of filler embolus into the ophthalmic a...

In this study, the interaction between the silica filler and polydimethylsiloxanes (PDMS) was investigated from the aspects of the bound rubber and morphological characterization. With special attention to the dynamic properties, the dynamic test was conducted by dynamic shear rheometer. The results show that the modified fillers disperse uniformly within PDMS matrix without aggregation and con...

Digital radiography was used to measure the radiopacity of 18 resin cements to determine the influence of inorganic filler content on radiopacity. Four disk specimens (n=4) of each light-curing cement were digitally radiographed alongside an aluminum step wedge using an intraoral sensor (XIOS Plus, Sirona, Germany), and their mean gray value measured. Percentage of filler by weight was determin...
