STUDIES ON VULCANIZATION ACCELERATOR-XLIV

Occupational Dermatitis Caused by Vulcanization Accelerator of Gloves

Three cases of occupational dermatitis due to additives to rubber gloves are discussed. These cases were not a result of latex allergy and their dermatitis caused by vulcanization accelerator in rubber gloves. Most people have heard of latex allergy, and some people avoid the use of latex products. However, some rubber-related contact dermatitis of hands is caused by additives such as vulcaniza...

1 Studies on Accelerator - Driven Transmutation Systems

Research and development on transmutation of long-lived radioactive nuclides are being carried out with an emphasis placed on the dedicated accelerator-driven systems at the Japan Atomic Energy Research Institute (JAERI) under the Japanese long-term program for research and development on partitioning and transmutation technology (OMEGA Programme). The preliminary design of the sodium-cooled so...

Theory & Practice Of Vulcanization

Critical behaviour for vulcanization processes

2014 We consider a polymer melt, with polymerization index N and a fraction p of cross linked monomers, for values of p close to the gelation threshold (p = 03C1c + 039403C1). Using a Ginsburg argument, we find that (in three dimensions) the Flory theory is qualitatively correct whenever N > (03C1c/039403C1)3. For shorter chains the critical exponents are expected to be of the percolation ...

Vibration Studies of the Stanford Linear Accelerator†

Vibration measurements of the linear accelerator structures in the SLC linac show a 1 micron rms vertical motion. This motion reduces to 0.2 micron rms motion when the cooling water to the accelerator structures is turned off. The quadrupoles have 250 nanometer rms vertical motion with the accelerator structure cooling water on and 60 nanometer motion with it off. These results together with me...
