The nss (no steady state) phototransduction mutant of the sheep blowfly Lucilia was studied electrophysiologically using intracellular recordings. The effects of the nss mutation on the receptor potential are manifested in the following features of the light response. (a) The responses to a flash or to dim lights are close to normal, but the receptor potential decays close to the baseline level...
Comparative Phenotypical and Molecular Analyses of Arabidopsis Grown under Fluorescent and LED Light
Comparative analyses of phenotypic and molecular traits of Arabidopsis thaliana grown under standardised conditions is still a challenge using climatic devices supplied with common light sources. These are in most cases fluorescent lights, which have several disadvantages such as heat production at higher light intensities, an invariable spectral output, and relatively rapid "ageing". This resu...
In this study, the effects of different light regimes on the reproductive activity of a typical Indo- Pacific coral reef rabbitfish, Siganus sutor, were evaluated. Forty- five adult fish were exposed to nine different photoperiod (8L: 16D, 12L: 12D, 16L: 8D) and light intensity (1000, 2000, 3000 lux) combinations with three replicates and five other fishes reared under indoor light condition (C...
Given the importance of Artemia as the most live feed used in the aquaculture industry, the interaction between light intensity and pH was investigated in two levels of light 1000 and 2000 lux, and three levels of pH 8, 9 and 10 on the percentage of hatching, percentage of umbrella stage and percentage of unhatched cyst on Artemia franciscana. To determine the percentage of hatching, percentage...
To gain a better understanding of molecular and biochemical events involved in light intensity adaptations of Dunaliella salina, we studied the expression of phytoen synthase (psy) gene; pigments, carbohydrates, proteins and lipids accumulation under two light intensities. The cells were pre-cultured under 50 µmol photon m-2s-1 light intensity and then transferred to two different light intensi...
The reaction of hydrogen peroxide and pheny -9-acridinecarboxylate in the presence of rhodamin B as a fluorophore leads to the emission of either bright blue light or bright red light, depending on the structure of fluorescer and reaction conditions. The light emitter responsible for the Chemi Luminescence (CL) reaction is acridone and that the blue light produced with out the fluorescers...
results the results show the artificial lighting obtained by difference methods of the overall lighting from natural lighting in closed blinds mode equal to 266 lux and night lighting 283.5 lux that they have no significant differences with each other (p = 0.269). as well as the illumination intensity obtained from a standard grid method is 283.5 lux and illumination intensity based on luminair...
The aim of this study was to assess the effect of different light intensities and photoperiods on growth, survival, and the yolk sac absorb of the Persian sturgeon, Acipenser persicus, larvae. Larvae were reared from hatching to yolk sac absorb (eight days) at four light intensities (0, 50, 150 and 300 lux) and three photoperiods (00L:24D, 12L:12D and 24L:00D) which consisted of seven treatment...
RF plasma was applied for the reduction of human blood and bovine blood in which essential proteins to lives were included. Atomic oxygen and singlet molecular oxygen are significantly important for the treatment of protein by RF oxygen plasma. The reduction rate of the protein was analysed by FTIR spectra, and the light emitted from oxygen plasma was detected by spectrometer. The ratio of emis...
