dilution is limited primarily in its sensitivity. However, this is of concern only if very small numbers of organisms are suspected in a particular specimen, because the lower limits of detection for a 10-μL aliquot of undiluted material would be approximately 100 cfu/mL. There exists the possibility of crossing of paths as the plates are tilted. We experienced this problem only: (i) on media t...

During their entire lives, weakly electric fish produce an uninterrupted train of discharges to electrolocate objects and to communicate. In an attempt to learn about activity-dependent processes that might be involved in this ability, the continuous train of discharges of intact Gymnotus carapo was experimentally interrupted to investigate how this pausing affects post-pause electric organ dis...

electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. electric motors account for between 43 and 46% of all global electricity consumption approximately. they give rise to about 6 040 mt of co2 emissions. end‐users approximately spend usd 565 billion per year on electricity [1]. in recent years, increase in e...
