QUALITATIVE COMMENTS (with 6 mg, orally) Effects were present in twenty minutes, and I took my portable radio into the garden at forty minutes just to pull weeds.

A car drove by with sitar music playing on its radio Why not. And by my hour number three, I am back where I started. That was quite a morning. ... 

The calculators, electronic watches, portable radios, and tape players that are so familiar to us are all powered by small, efficient, dry cell batteries. The common dry cell battery was invented more than 100 years ago by George Leclanche (1839-1882), a French chemist. In its acid version the dry cell battery contains a zinc inner case that acts as the anode and a carbon rod in contact with a moist paste of solid Mn02, solid NH4C1, and carbon that acts as the cathode (Fig. 11.14). The half-cell reactions are complex but can be approximated as follows ...

In the late 1960s and 1970s, more Asian companies entered the U.S. marketplace. The typical attitude within U.S. management was that their products were of lesser quality and they would not hurt our business. Remember the small portable radios from Japan At first they were of poor quality, but the Japanese companies endeavored to try to improve their products and to be more competitive. Within a few years they became a major force in the electronics marketplace. Even today I see companies that still view their competition and market as only within the United States.
