abstract this research was conducted to study the effects of different light colors on growth indices (growth rate and specific growth rate), feed conversion and survival rate in tiger barb (barbus tetazone) fish for 6 weeks. 120 fish with an average weight 75 ±0.02 were respectively divided in four groups of white, natural, green and blue colors (with three replicates for each treatment). fish...

This paper illustrates the possibility of measuring chlorophyll (Chl) content and Chl fluorescence parameters by the solar-induced Chl fluorescence (SIF) method using the Fraunhofer line depth (FLD) principle, and compares the results with the standard measurement methods. A high-spectral resolution HR2000+ and an ordinary USB4000 spectrometer were used to measure leaf reflectance under solar a...

introduction preterm infants are exposed to irregular light for several weeks or months in the neonatal intensive-care unit (nicu). this lack of maternal entrainment, the exposure to irregular extrauterine lighting and care in the nursery may contribute to the disturbances in body temperature, sleep and physiological changes that are commonly experienced by preterm infants. materials and method...

The objective of this study was to review the literature on sperm transport in the mare. During this process the sperm cells must reach the oviducts in order to fertilize the oocyte, but before reaching this site it must go through the uterus that is a hostile environment at this moment since there is an inflammatory reaction in this location that aims to eliminate excess spermatozoa and bacter...

Desipramine HCl, 10 mg/kg i.p. twice daily, produced subsensitivity to the hypothermic effects of nicotine, 1 mg/kg, after 1 and 2 weeks of treatment in male Sprague-Dawley rats, Phenelzine sulfate, fluoxetine HCl, and bright artificial light produced the same effect. The capacity of three chemically distinct classes of anti-depressants and bright artificial light (a treatment for seasonal depr...

Artificial neural network (ANN) has application in communication engineering in diverse areas such as channel equalization, channel modeling, error control code because of its capability of nonlinear processing, adaptability, and parallel processing. On the other hand, wavelet transform (WT) with both the time and the frequency resolution provides the exact representation of signal in both doma...

Here we report a new and efficient synthetic method for reduced graphene oxide using visible-light and plasmonic nanoparticles at room temperature. The r-GO prepared using visible light showed excellent fluorescence quenching properties and target detection capabilities.
