Excellent dispersion of functionalized graphene (FG) sheets in polystyrene was achieved relying on the reaction of "living" poly(glycidyl phenyl ether) chains onto graphene sheets. The physical aging of polystyrene was substantially accelerated by the presence of FG sheets at low filler content, retaining film transparency and increasing the electrical conductivity.

PURPOSE Mouthguards are available to provide protection from stomatognathic injury during sports. The aim of this study was to examine the thickness of each part of mouthguard sheet depending on the thickness of mouthguard sheet material. METHODS Cross stripes (10 x 10 mm) were printed in mouthguard sheets. We measured the thickness of each cross stripe area using a measuring-device (R). Two ...

A distinct feature of an adaptive e-learning hypermedia system (AEHS) is the learner model it employs, that is, a representation of information about an individual learner. Learner modeling and adaptation are strongly correlated, in the sense that the amount and nature of the information represented in the learner model depend largely on the kind of adaptation effect that the system has to deli...

This article outlines a hybrid method, incorporating multiple techniques into an evaluation process, in order to select competitive suppliers in a supply chain. It enables a purchaser to do single sourcing and multiple sourcing by calculating a combined supplier score (CSS), which accounts for both qualitative and quantitative factors that impact on supply chain performance. By performing a clu...

A distinguishing feature of the period preceding the 2007/08 financial crisis was the sizeable increase in private sector debt observed across many countries. A key component of household liabilities is mortgage debt and with many countries experiencing persistent increases in house prices from the mid-1990s onwards, a marked increase in this aspect of household leverage was observed. While agg...

In this paper, we present a unified framework for our previous constructions of martingales with the same one-dimensional marginals as particular cases of processes increasing in the convex order. This framework encompasses our former uses of Lévy sheets, Sato sheets and self-decomposable laws. New examples of processes increasing in the convex order are also exhibited, but we do not know how t...

The purpose of a Safety Data Sheet (SDS), formerly known as Material Safety Data Sheets (MSDS), is to provide information on the hazards of working with a chemical and procedures that should be used to ensure safety. State and Federal law require that employers obtain an SDS for each hazardous substance they use or store and make the SDS available to employees. The PI/instructor is responsible ...
