The highest feeding frequency occurred at 16:00~00:00 and a higher one at 04:00~08:00. The feeding frequencies of the fish under the light intensity of 100~500Lx for the larvae of 5 DAH and 10~100Lx for larvae of 8 and 12 DAH increased, compared to those under the light intensity of OLx, 10Lx, and 1000Lx.
The results with strong evidence showed that Pavlova viridis grew well within a wide range of temperature (6-30℃ ), salinity (1. 002-1. 006) and light intensity (500-10000 lx), especially in low salinity (1. 002) and low light intensity (400-500 lx).
Brachionus calyciflorus Pallas were cultured in both single and group rotifers in the medium of 1. 0, 0. 5 and 0. 25 mL under the experimental conditions of 25℃, light intensity about 4000 lx(LD=18 : 6) and the food concentration about 1. 0×10~6 cells/mL of Chlorella sp. In single culture, the mean egg numbers per mother female were 12. 0 ind.
Before seedling collection, the ♀♂clones were mixed and the photoperiod was transferred from long light(continuous illumination) to short light (L∶D 10∶14) and the growth of clones was continuously observed. The results showed that it took 11 days to enter into developmental stage and the cell number increased 40%.
The results showed that the biomass of yellow perch which was reared under the 16L∶8D photoperiod is 2.90 times compared to that under Amb photoperiod,and the feed parameter was lower,and decreased to 54.8% of the latter.
In light of Brenti's work on certain R-polynomials, this formula raises interesting questions about the possibility of relating Ext groups between Weyl modules to Kazhdan-Lusztig combinatorics.
Light microscopy revealed compressed villi, oedema, mononuclear cell filtration, and vacuolization on the cytoplasm of epithelial cells in the jejunum of hyperlipidemic rats.
A seaweed-chamber experiment was performed, indicating that gaseous I2 is one of the important precursors that lead to new particle formation in the presence of solar light in the ambient air at the coastal tidal area.
Investigation on the acute biochemical effects of light rare earths on rat serum by NMR-based metabonomic approaches
1H-NMR spectroscopy and pattern recognition (PR) method were used to assess the acute biochemical effects of light rare earths.
But when it was irradiated under UV illumination or solar irradiation for some time, the catalyst could be reused without loss of catalytic activity.
For three tested samples, under UV illumination CCT01 has the highest activity for MB photocatalytic degradation, while in the case of RB, CCT02 is the most active photocatalyst.
Under visible light illumination, CCT005 has the highest activity for both MB and RB photocatalytic degradation.
After treatment of the mycelium with 5-azacytidine, the protoperithecia formation was accompanied by inversely proportional changes in the formation of conidia, both in the dark and after illumination.
A New Type of Adaptation of the Cyanobacterium Spirulina platensis to Illumination Conditions
However, in habitats lacking sufficient nutrition and with higher light intensity, survival rates and space-occupying ability of two kinds of seedlings (sexual and asexual produced) were low and the space would be preempted by grown-up plantlets.
The time required for fluorescence to reach its peak intensity and the degree of fluorescence quenching depending on light intensity are analyzed.
In the diatoms limited in nitrogen and assimilating exogenous glucose, P was found to decrease or increase depending on the light intensity, glucose concentration, and the duration of exposure.
In the diatoms assimilating both nitrate nitrogen and glucose, compared to those supplied with nitrates alone, P was higher at the medium and high light intensities and lower at the low light intensity.
High light intensity improved the physiological state of carp yearlings, while zero illumination had an inverse effect.
