Coenzyme A and Aldolase in Rubber-bearing Plants
Nature, 1958THERE is evidence that the biosynthesis of rubber from carbon dioxide and water in Parthenium argentatum 1 may proceed through acetate and β-methylcrotonate, and that acetate can also act as a precursor of rubber in Hevea brasiliensis 2. Co-enzyme A probably plays a vital part in the process.

Determination of Rubber in Rubber-Bearing Plants
Rubber Chemistry and Technology, 1933Abstract THE determination of the true rubber content of both raw and manufactured rubber has been the subject of extensive investigation. Search has failed to reveal any corresponding record covering studies applicable to rubber-bearing plants.

Shape optimization of a rubber bearing
International Journal of Fatigue, 1991Abstract Large deformations in a rubber bearing between two conical tubes may lead to squashing folds that can cause local rupture of the rubber followed by complete destruction of the bearing. A new method, CAO (computer-aided optimization), which is based on the simulation of biological growth, is used to avoid these squashing folds by reducing the

Behaviour of lead-rubber bearings
Structural Engineering and Mechanics, 1998Experimental work undertaken to investigate the behaviour of lead-rubber bearings under compression and a combination of compression and shear or rotation has been reported on elsewhere. However, it is difficult to determine the state of stress within the bearings in terms of the applied forces and the interaction between the lead plug and the steel ...

An Investigation of Adaptive Rubber Bearings
Volume 8: Seismic Engineering, 2016Proposed in this study are several innovative seismic isolators composed of rubber materials that are called adaptive rubber bearings based on their adaptive characteristics. The materials used in the proposed isolators are free of lead commonly found in lead rubber bearings.

Extraction and Characterization of Latex and Natural Rubber from Rubber-Bearing Plants
Journal of Agricultural and Food Chemistry, 2010Consecutive extraction of latex and natural rubber from the roots of rubber-bearing plants such as Taraxacum kok-saghyz (TKS), Scorzonera tau-saghyz (STS), and Scorzonera Uzbekistanica (SU) were carried out. Latex extraction was carried via two methods: Blender method and Flow method. The results of latex extraction were compared.

Tetracyclosqualene and its bearing on the structure of cyclized rubber
Tetrahedron Letters, 1963Abstract Recently we reported that cyclized rubber consists of six-membered rings fused into predominantly bicyclic structures which are connected by methylene groups and/or uncyclized isoprene units. Each of the fused ring structures is presumed to contain a single tetra-, tri- or di-substituted double bond, the relative amounts of which are ...
