This paper reviews the operation, design, and performance of the uni-traveling-carrier-photodiode (UTC-PD). The UTC-PD is a new type of photodiode that uses only electrons as its active carriers and its prime feature is high current operation. A small signal analysis predicts that a UTC-PD can respond to an optical signal as fast as or faster than a pin-PD.(More)
This study aimed at comparing fatty acid contents of rotifers cultured with different methods after nutritional enrichment in order to evaluate the rotifer quality produced by these methods. Rotifers were cultured using either a batch or a continuous culture. From the batch culture, three experimental subpopulations were used, sampled from the culture at 1,(More)
Survival in larval rearing experiments is difficult to estimate due to accidental losses and periodic sampling. The number of sampled fish can be a large proportion of the stocked ones, making it difficult to calculate the overall survival rate and mortality coefficient as this is based on the initial number. Here, a new method of calculating survival is(More)

The feeding effects of freshwater cladoceran Moina macrocopa to the larvae and juveniles of red sea bream were investigated. M. macrocopa was mass-cultured with freshwater Chlorella as feed and was enriched nutritionally with a commercial enrichment diet. Because M. macrocopa die in seawater within a few minutes, the cladocerans were frozen after(More)
Delphinium ‘Blue Bird’ seedlings weregrown in heated (air temperature >15 ) and unheatedglasshouses in winter and treated with foliar sprays of gibberellic acid(GA3) or drenched with uniconazole (UZ). The unheated seedlings wereexposed to temperatures as low as 5 . Under bothheated and unheated growing conditions, leaf differentiation was retarded by theGA3(More)
