BACKGROUND The aims of this study were to determine the clinical effectiveness of optical and video low vision aids (LVA) and analyze the characteristics of the visually impaired at the low vision clinic of Chang Gung Memorial Hospital. METHODS The use of LVA to improve distance and near visual functions was evaluated in 203 new patients from 1998 through 2001 at our clinic. The age, gender, ...

His study aims to analyze the extent which a mixture of wood waste and used newsprint can be as raw material for making paper.This completely randomized design with two replications. where treatment given is composition between pulp old pulp, each consisting 0 : 100% (A), 30% 70% (B), 50% (C), (D) 0% (E) oven-dry weight per sheet paperThe physical properties paper tested in form tear index, ten...

Flotation deinking of old newsprint (ONP) using polydiallyldimethylammonium chloride (polyDADMAC) as the only deinking agent was studied. The results demonstrate that polyDADMAC can neutralize dissolved anionics to form small particles. These small particles, together with ink, filler, and fines, strongly adsorbed onto air bubble surfaces and functioned as particle foaming agents. Therefore, no...

this work investigates the feasibility of using recycled high density polyethylene (rhdpe), recycled polypropylene (rpp) and old newsprint fiber (onp) to manufacture fiber reinforced composites. the boards were made through air-forming and hot press. the effects of the fiber loading and coupling agent content on tensile, flexural, internal bond properties and water absorption and thickness swel...
