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...

An initial experimental study was conducted to evaluate the effects of binaural beats on fish growth performance. A 90-day trial with four triplicate groups was conducted with 240 zebrafish, Danio rerio, under aquarium conditions. Binaural beat file complexes were played for each aquarium using computer controlled directional speakers for 0 min d-1(Control), 90 min d-1(Group 1), 180 min d-1 (Gr...

the objective of this study was to evaluate the effect of accell connexus(®) on the quality and rate of healing in experimental defects of rabbit calvarium compared to bio-oss®.twelve 2.5-3.5 kg weighing new zealand white rabbits were used. three defects (3×6 mm) were created in the cranium of the animals subsequently filled with accell connexus(®), bio-oss® or served as controls. the animals w...

a thermophilic anaerobic contact reactor for the treatment of potato-processing wastewaterswas designed as a continuous-flow, completely-mixed homogeneous system. the reactor was operated at ten different organic loading rates ranging from 0.84 g cod/l·d to 7.00 g cod/l·d for a duration of approximately 250 days. the fundamental way to maintain optimum operating conditions of anaerobic digestio...

background: hyaline cartilage defects exhibit a major challenge in the field of orthopedic surgery owing to its limited repair capacity. on the other hand, mesenchymal stem cells (mscs) are regarded as potent cells with a property of cartilage regeneration. we aimed to optimize marrow-derived msc chondrogenic culture using a small bioactive molecule referred to as bio. methods: mscs from the ma...

The objective of this study was to investigate the growth rate of Chlorella vulgaris for CO2 biofixation and biomass production. Six mathematical growth models (Logistic, Gompertz, modified Gompertz, Baranyi, Morgan and Richards) were used to evaluate the biomass productivity in continuous processes and to predict the following parameters of cell growth: lag phase duration (λ), maximum specific...

broomrape would have irreversible effects on tomatoes in all growth stages and the damage would be unrecoverable. in order to chemically control orobanche spp with consumption of bio-fertilizer in tomato cultivation, an experiment as factorial based on complete randomized blocks design in three replications and 12 plots was carried out at a farm which is located in mahabad city (iran). in this ...

background: basil (ocimum basilicum l.), a member of the lamiaceae family, has traditionally been used as a medicinal plant in the treatment of headaches, coughs, diarrhea, constipation, warts, worms, and kidney malfunctions. objective: to investigate the foliar application effects of bio-stimulators and bio-fertilizers on morphological and phytochemical traits of basil (ocimum basilicum l.). m...

 Environmental enrichment is one of the methods for improving fish growth performance. In the present trial, the effects of both light color and music on growth performance and survival of goldfish (Carassius auratus) (initial mean weight: 4.15±0.08 g) were investigated for 2 months. Two light color treatments (red light and white light) and three music treatments (M0: without music, M30:30 min...
