Normal Drosophilia learn to avoid an odorant associated with electric shock. An X-linked mutant, dunce, has been isolated that fails to display this learning in spite of being able to sense the odorant and electric shock and showing essentially normal behavior in other respects.

Do people sometimes seek to atone for their transgressions by harming themselves physically? The current results suggest that they do. People who wrote about a past guilt-inducing event inflicted more intense electric shocks on themselves than did those who wrote about feeling sad or about a neutral event. Moreover, the stronger the shocks that guilty participants administered to themselves, th...

In a recent, discussion of approach-avoidance conflict theory, Miller (1959) assumed that the strength or excitatory potential of the approach response should vary with factors which have been found to affect performance in nonconflict situations, namely: (1) the number of reinforced trials, (2) the strength of drive motivating the approach response, (3) the delay of reward, and (4) the amount ...

Each of eight rats was located in the experimental chamber mounted with two levers. Lever-pressing to either of the two was maintained by a schedule of food. After that, a punishment schedule of electric shocks was added. Neither the reinforcement nor the punishment schedule was programmed on the other lever, i.e. the non-reinforced alternative. The effect of reinforcement, and the joint effect...

BACKGROUND The aim of the study was to evaluate the effects of micro-electric current on sodium hypochlorite's (NaOCl's) tissue-dissolution abilities, compared with other activation methods, including sonic, ultrasonic, pipetting, and temperature. METHODS Bovine muscle tissues (n = 154) with standard sizes and weights were prepared and divided into two temperature groups: room temperature and...

Carter, A. O., and Morley R. (1969). Brit. J. industr. Med., 26, 217-223. Electric current flow through human skin at power frequency voltages. Alternating power voltages were applied to small pieces of living skin. Current and voltage were recorded continuously using voltages from 25 V to 250 V. At the lower voltages the skin appeared unaffected, but rapid destruction occurred at the higher vo...

Despite numerous studies on spinal neuronal systems, several issues regarding their role in motor behavior remain unresolved. One of these issues is how electric fields associated with the activity of spinal neurons influence the operation of spinal neuronal networks and how effects of these field potentials are combined with other means of modulating neuronal activity. Another closely related ...

Complies with the regulations of the University and meets the accepted standards with respect to originality and quality. Batteries, ultra capacitors (UCs), and fuel cells (FCs) are widely being proposed for electric and plug-in hybrid electric vehicles (EVs/PHEVs) as energy sources. The increasing popularity of EVs and PHEVs can be attributed to the savings in fuel costs, compared to conventio...
