Rubber Tummy
… through the lens of a ravenous woman. I wrote Rubber Tummy to grant women the freedom to talk about eating, sex, and indulgence outside the current cultural limitations, which ask that these desires be small, infrequent, and quiet. My collection also explores the mystic nature of sharing food …

Ultrasonically Aided Extrusion of Rubber Nanocomposites and Rubber Blends
Dispersion of nanofillers in rubber nanocomposites and distribution of components and their interaction in rubber blends is known to significantly affect their rheology and performance characteristics. Application of ultrasonic waves during extrusion is considered a possible means to influence …

Fatigue in rubber vulcanisates
… fatigue on the structures of various natural rubber networks. The change in network structure of a conventional vulcanisate on a single extension manifests itself as permanent set. The change in network structure has been assessed by the use of the chemical probes, propan-2-thiol/piperidine, …

Analysis of rubber vulcanisates
… of sulphenamide accelerators in vulcanised rubber compounds, has been developed. During the vulcanisation process, the accelerators decay, liberating specific amines which have been solvent extracted, derivatised with 1-chloro-2,4-dinitrobenzene and the yellow coloured zwitter ion analysed …

Civilized people in uncivilized places : rubber, race, and civilization during the Amazonian rubber boom
… to become civilized began to be questioned.Rubber, an increasingly important and lucrative imperial resource at the end of the nineteenth century, brought people from around the world to the Amazon basin. This resulted in the creation of a “contact zone” of different peoples, cultures, and …

Network defects in vulcanised rubber
The molecular weight of natural rubber is very high and must be reduced by mastication so that it has sufficient plasticity to enable the incorporation of compounding ingredients. Such a reduction in molecular weight increases the number of elastically ineffective chain ends which reduces the …

Coagulant dipping of natural rubber latex
… been made of' the coagulant dipping of natural rubber latex using calcium, chloride as the coagulant. The primary object of the investigation was to deepen understanding of the kinetics and the mechanisms of deposition. Results are given for the effect of variables such as solids content, latex …

Peroxide prevulcanization of natural rubber latex
… of induced decomposition of tBPIB by certain non-rubber substances, and termination by recombination of radicals derived from tBPIB. But, the reason for the difference in the reaction order with respect to tBPIB concentration, at the initial stage of the reaction and during the run is not clear. …

On the puncture strength of rubber
… study has been carried out on the fracture of rubber by cylindrical indentors. Several phenomena have been identified which affect the puncture process. It has been observed that a ring crack forms on the rubber surface before puncture occurs. By treating this crack as a starter crack, an …

Chemistry of tellurium applied to rubber
A study of tellurium and its compounds in rubber has been carried out by using them as cross linking agents and as ultra-accelerating agents when employed together with a tetraalkylthiuram disulphide. Reactions of tellurium tetrahalides with model alkenes, rubber solutions and solid rubber were …
