Fluoride Uptake and Net Primary Productivity of Selected Crops
Crop field soil collected from Sambalpur University campus of Odisha and treated with various fluoride concentrations was used to raise selected local crops. Background concentration of total and leachable fluoride content in soil was 95.19 and 8.89 ppm respectively. At the time of harvest of the crops, the total fluoride content was found to decrease and leachable fluoride content was found to...
متن کاملImpacts of urbanization on net primary productivity in the Pearl River Delta, China
Great changes in land use/land cover from rapid urbanization have occurred in the PearlRiver Delta, China. As the primary cause of land development in the urbanization process,urban expansion has mostly occurred on land with higher NPP, significantly impacting theregional ecosystems. The primary purpose of this study was to reveal the impacts of urbanexpansion on the regional NPP. The land cove...
متن کاملComparison of Fluoride Uptake into Enamel from Sodium Fluoride Gel 0.05% Produced in Iran and Stannous Fluoride 0.4% Gel
Background & Aims: The present study compared fluoride uptake into enamel from sodium fluoride 0.05% gel and American Dental Association approved fluoride gel (Stannous fluoride 0.4% , Sultan Co.) when used on healthy enamel of the intact teeth. Methods: In an experimental study, 30 intact teeth extracted for orthodontic purposes were randomly assigned into two groups of 15 teeth. The teeth wer...
متن کاملUPTAKE OF Zn”” AND PRIMARY PRODUCTIVITY IN MARINE BENTHIC ALGAE1
The rate of uptake of Zn O5 from natural sea water and the primary production of 6 species of marine benthic algae were measured in light and dark bottles suspended in a running sea water aquarium under constant light and temperature conditions. Uptake and production of one species (Chaetomo~pha Linus) were also measured in bottles suspended at different depths in a marine pond in order to achi...
متن کاملThe allocation of ecosystem net primary productivity in tropical forests.
The allocation of the net primary productivity (NPP) of an ecosystem between canopy, woody tissue and fine roots is an important descriptor of the functioning of that ecosystem, and an important feature to correctly represent in terrestrial ecosystem models. Here, we collate and analyse a global dataset of NPP allocation in tropical forests, and compare this with the representation of NPP alloc...
