In this study I examine the relationship between syntactic working memory and intermediate gap positions in longdistance filler-gap dependencies. An “intermediate” gap position is a structural position, distinct from verbal argument positions, which is available to the filler at a clause edge between its surface dislocated position and its original canonical position. I will use anterior negati...

This review aims to present recent advances in the synthesis and structure characterization as well as the properties of polymer layered silicate nanocomposites. The advent of polymer layered silicate nanocomposites has revolutionized research into polymer composite materials. Nanocomposites are organic-inorganic hybrid materials in which at least one dimension of the filler is less than 100 nm...

The purpose of this study was to evaluate the filler compositions of recently available light-cured resins. The composition of each resin paste was evaluated using an energy dispersive X-ray fluorescence spectrometer. Scanning electron microscopic observation of the polymerized resin pastes was also conducted. The main component of each resin composite was Si, while the other elements detected ...

In this paper, a novel approach for the design of cohort models for word spotting in continuous speech is presented. This new approach is based on modifying the probability density function of a conventional filler so that regions in the feature space that are related to the keyword will be reduced or removed. By modifying these regions, the filler and keyword models become more orthogonal in t...

The corrosion behavior of the fusion zone of gas tungsten arc (GTA) welds of AA6061 alloy was studied. Role of gas tungsten arc welding techniques such as continuous current (CC) and pulsed current (PC) and reference filler (AA5356) were studied. Role of different grain refiners such as scandium, zirconium and Tibor in the reference filler was studied. Dynamic polarization testing was used to d...

Mixed matrix membrane used to selective removal of CO2 was considered as an efficient solution to energy and environmental sustainability. In this study, a MMM that consists of amide functionalized porous coordination polymer filler (MIL-53-NH2) was successfully prepared, which sharply promotes the CO2/N2 selectivity from 44 (neat polymeric membrane) to 75. Remarkably, the positive effect of am...

OBJECTIVES This study sought to determine the efficacy and safety profile of calcium hydroxylapatite filler in the treatment of acne scars. METHODS Ten subjects with a variety of acne scars were treated with calcium hydroxylapatite filler. RESULTS Saucerized acne scars responded to treatment; ice-pick scars did not. Results lasted, at least to some degree, for 12 months after treatment. No ...

High-free-volume glassy polymers, such as polymers of intrinsic microporosity (PIMs) and poly(trimethylsilylpropyne), have attracted attention as membrane materials due to their high permeability. However, loss of free volume over time, or aging, limits their applicability. Introduction of a secondary filler phase can reduce this aging but either cost or instability rules out scale up for many ...

We perform molecular dynamics simulations of an idealized polymer melt surrounding a nanoscopic filler particle. We show that the glass transition temperature T(g) of the melt can be shifted to either higher or lower temperatures by tuning the interactions between polymer and filler. A gradual change of the polymer dynamics approaching the filler surface causes the change in the glass transitio...

In this study, the mechanical and tribological properties of 4 different types of welding filler metals were examined on a 1.6959 steel (DIN35NiCrMoV12-5) by the Gas Tungsten Arc Welding process. The fillers used in this study include ER70S-6, ER80S-G, ER80S-Ni1, ER80S-B2. The main reasons for choosing these fillers in this study are their availability and close chemical composition to the base...
