For the first time, maps of surface concentration of nitrogen dioxide (NO2) are presented for the Colombian territory. NO2 surface concentrations for the year 2007 are inferred based on two sources of tropospheric NO2 column data: (1) a simulation using a... see more

Nitrogen-dopped activated carbon was synthesized to see its effect on the characterization of the nitrogen surface functional groups, crystal size, and morphology of the resulting sample. Synthesis of nitrogen-doped activated carbon was carried out by var... see more

Paper description:Indole-acyl esters (ID), nitrogen (N) or phosphorous (P) fertilizers can mitigate the toxic effects of Cd and Pb on plant growth.The Box-Behnken three-variable partial factorial design was utilized to study the interaction effects of thr... see more

Nitrate is the most common groundwater contaminant. The objective of this experiment was to determine if Triticum aestivum (wheatgrass) is able to act as a phytoremediator of nitrates present in wastewater and how nitrogen (N) accumulation in wheatgrass i... see more

Nitrogen (N) has commonly been applied in Eucalyptus stands in Brazil and it has a direct relation with biomass production and chlorophyll content. Foliar N concentrations are used to diagnose soil and plant fertility levels and to develop N fertilizer ap... see more

Polyamines (PAs) seem to play an overwhelming role in plant growth and developmental processes. They are found to be essential for cell viability, cell division, prolongation of cell division, and cell elongation and modification (Evans and Malmberg, 1989... see more

Purple coneflower (Echinacea purpurea L.), is a medicinal plant whose mineral nutrition has been scarcely studied. In this work, using potted plants, we evaluated Echinacea nutrient uptake and biomass accumulation in relation to nitrogen fertilization dos... see more

In the studies and production of bioethanol, the preferred fermenting yeast (Saccharomyces cerevisiae) is usually cultured in liquid broth that contains yeast extract and peptone. However, the use of these laboratory and scientific grade chemicals is cost... see more

The objectives of this research were to examine the effect of Sechium edule ethanolic extract to repair beta pancreas cells damage and tomeasure nitrogen oxide (NO) concentration in streptozotocin-induced rats. Type I diabetic rats were obtained by intrap... see more
