The Editor, I feel that Sawyer and Bennett (2006) imply that there is something intrinsically hazardous about natural rubber latex (NRL) gloves. The evidence shows this not to be the case. NRL gloves were used for many years in health care and laboratory work with only a rare incidence of latex allergy. The problem arose when the health care sector decided to adopt a policy of general glove use...

To develop a matched sealing material for socket rehabilitation of grey cast iron pipes, an epoxy resin is modified by the addition of different components to improve the flexibility. Three different modifications are made by adding ethylene-propylene diene monomer (EPDM) rubber powder, reactive liquid polymer (ATBN) and epoxidized modifier. In this paper the effect of the modification method a...

The RAMP Anthrax Test Cartridge for detecting Bacillus anthracis was validated for use in the field for detection of B. anthracis spores in visible powder residues on 7 nonporous environmental surfaces. Six teams of trained first responders and civil support personnel in Class C personal protective equipment sampled visible powder residues on plastic, stainless steel, ceramic tile, wood, rubber...

The use of (recycled) plastics and (waste) vulcanized rubber powder is the main polymer raw materials, composite organic additives are selected to fully combine with asphalt components. physical chemical reactions between different components completed in dynamic mixing, establishing a morphology structure similar thermoplastic elastomers (TPEs), highly asphaltized alloy material. TPE-modified ...
