Different paper grades have been used to evaluate the optical formation measurements for newsprint and SC paper. Formation of the SC papers has been measured both before and after supercalendering to see how it affects the optical measurements. The optical measurements have been compared to β-radiation measurements and the results showed that optical measurements give a fair estimation of the f...

The function(s) of soluble silicates in repulpinghashing and flotation deinking of waste newsprint/magazine were investigated extensively, under optimized conditions. During repulping/washing, silicate ’s response was characteristic of a buffer and a detergent. It was responsible for a 3.0% increase in I S 0 brightness. In repulping/flotation, silicate accounted for a 6.1% increase in I S 0 bri...

In the newspaper printing industry, offset is the dominating printing method and the use of multicolour printing has increased rapidly in newspapers during the last decade. The offset printing process relies on the assumption that an uniform film of ink of right thickness is transferred onto the printing areas. The quality of reproduction of colour images in offset printing is dependent on a nu...

BACKGROUND This study investigates the coverage of adherence to medicine by the UK and US newsprint media. Adherence to medicine is recognised as an important issue facing healthcare professionals and the newsprint media is a key source of health information, however, little is known about newspaper coverage of medication adherence. METHODS A search of the newspaper database Nexis®UK from 200...

We study the 2-D Helmholtz equation in perturbed stratified media, allowing the existence of guided waves. Our assumptions on the perturbing and source terms are not too restrictive. We prove two results. Firstly, we introduce a Sommerfeld-Rellich radiation condition and prove the uniqueness of the solution for the studied equation. Then, by careful asymptotic estimates, we prove the existence ...
