Properties of samples containing polyurethane (PU), poly(vinyl acetate) (PVAc) and nanosize particles of calcium carbonate (CaCO3) are correlated with concentrations of these components. Interphase phenomena in PU/PVAc/CaCO3 nanohybrids have been studied before, we focus here on wear and scratch resistance. In addition to polymer blends containing CaCO3, the effects of adding CaCO3 with grafted...

results all patients experienced improvement in the wrinkles of the side treated by the combination therapy compared to the other side. in addition, less complication was observed in the side that underwent combination therapy. conclusions our study showed that autologous fat in combination with platelet gel might have better cosmetic results as well as lesser complications in the healing of na...

joining of titanium alloys to other materials especially steels has attracted much attention in recent years due to the exceptional properties of titanium such as excellent corrosion resistance and mechanical properties and its increasing application in various industries. according to the fe-ti binary phase diagram, these two elements do not have complete solubility. this leads to difficulties...

Various noncanonical sentence constructions are derived from basic sentence structures by a phrase displacement called Movement. The moved phrase (filler) leaves a silent copy at the extracted position (gap) and is reactivated when the hearer/reader passes over the gap. Consequently, memory operations are assumed to occur to establish the filler-gap link. For languages that have a relatively fr...

A new scheme of detecting fillers in spontaneous speech recognition process was developed. When a filler hypothesis appears during the 2 pass decoding of a speech recognizer with two-pass configuration, a prosodic module checks the morpheme which is hypothesized as a filler and outputs the likelihood score of the morpheme being a filler. When the likelihood score exceeds a threshold, a prosodic...

In hybrid laser–MIG keyhole welding, anti-crack elements can be added into the weld pool through a filler metal in anticipation of compensating mass loss, preventing porosity formation and improving compositional and mechanical properties of the welds. Understanding the mixing and diffusion of the filler metal in the molten pool is vital to achieve these desired objectives. In this study, mathe...

Rubber-filler composites are a key component in the manufacture of tyres. The filler provides mechanical reinforcement and additional wear resistance to the rubber, but it in turn introduces non-linear mechanical behaviour to the material which most likely arises from interactions between the filler particles, mediated by the rubber matrix. While various studies have been made on the bulk mecha...

We assessed the use of a filler compound together with the osteoinductive demineralized bone matrix (DBM), Colloss E. The filler was comprised of carboxymethyl-cellulose and collagen type 1. The purpose of the study was to see if the filler compound would enhance the bone formation and distribute the osteoinductive stimulus throughout the bone defect. Six sheep underwent a bilateral humerus dri...

I Since the early days of generative grammat the study of "unbounded dependencies" such as arD-questions and reladve clauses has occupied a centrd place in both qmuctic theory and language processing research. The problem that such constructions pose is as follows. In a normal rzD-question, a wb' phrase is tlpically displaced to the left periphery of a clause (rVlnt did you say -to John?);.this...
