There are many domains in which understanding has brought_about widespread and quite appropriate reduction in ritual and fear .

Perhaps the most illuminating example of the reduction of fear through understanding is derived from our increased knowledge of the nature of disease .

An attempt to improve the life of the anodes or the efficiency of the plasma generators must , therefore , aim at a reduction of the anode loss .

(E. Gellhorn, "Prolegomena to a theory of the emotions"...)

On_the_other_hand , the temporary reduction in hypothalamic excitability through the injection of a barbiturate into the posterior hypothalamus causes a lessening in frequency and amplitude of cortical strychnine spikes until the hypothalamic excitability is restored .

Consequently , if for any reason the hypothalamic excitability falls below the physiological level , the lessened hypothalamic cortical discharges lead to a diminished state of activity in the cortex with consequent reduction in the cortico-fugal discharges .

[ noun ] (chemistry) any process in which electrons are added to an atom or ion (as by removing oxygen or adding hydrogen); always occurs accompanied by oxidation of the reducing agent

It was possible to make estimates of the quantum yield by observing the extent of reduction of a uranyl_oxalate actinometer solution illuminated for a known time in a typical reaction cell and making appropriate conversions based on the differences in the absorption_spectra of uranyl_oxalate and of chlorine , and considering the spectral distribution of the light source .

They indicated that a 4 - day retention , aerated lagoon would give 60 to 76 per_cent BOD reduction .

The BOD in the effluent averaged 58 mg / l , a 76 - per_cent reduction over the 24 - hr period .

[ noun ] the act of reducing complexity
