Microbiological deterioration of vulcanized rubber.
Data are presented which show that the constitution of the recovery medium exerts an appreciable effect on the apparent thermal resistance of spores of Putrefactive Anaerobe 3679. The routine use of a simple yeast extract-starch medium (YES) as a recovery medium in thermal resistance studies on this organism is recommended. In addition to giving thermal resistance values comparable to those obt...
متن کاملThermal Properties and Three-Phase Structure of cis-1,4-Polybutadiene
The thermal properties of cis-1,4-polybutadiene (cis-PBD) were investigated in dependence of content of cis units and of linearity of the main chain. cis-PBD grades containing a fraction of cis-segments ranging from 93 to 98 %, and with linear or branched chains, were analyzed. Upon isothermal crystallization from the melt at -26 °C for 1 h, followed by cooling to below the glass transition tem...

متن کاملVulcanized rubber foot for lower limb amputees.
A prosthetic workshop was started some years ago at the S.M.S. Medical College Hospital , Jaipur , t o meet the growing demands of the local populat ion. Unlike the premier limb-fitting centres in India which still cater for the more affluent sections of society, it was decided that this centre would also look after the p o o r rural amputees . I t soon became apparent that a disturbing number ...
متن کاملType Bonding Strength Modeling of Polyurethane to Vulcanized Rubber
Tires manufactured from polyurethane (PU) have been espoused recently for reduced hysteretic loss, but the material provides poor traction or poor wear resistance in the application, requiring inclusion of a traditional vulcanized rubber tread at the contact surface. The tread can be attached by adhesive methods after the PU body is cured, or the PU can be directly cured to reception sites on t...
