Application of Different Simulated Spectral Data and Machine Learning to Estimate the Chlorophyll a Concentration of Several Inland Waters [PDF]
arXiv, 2019 Water quality is of great importance for humans and for the environment and has to be monitored continuously. It is determinable through proxies such as the chlorophyll a concentration, which can be monitored by remote sensing techniques. This study focuses on the trade-off between the spatial and the spectral resolution of six simulated satellite ...

Optical Method for Estimating the Chlorophyll Contents in Plant Leaves
Italian National Conference on Sensors, 2018 This work introduces a new vision-based approach for estimating chlorophyll contents in a plant leaf using reflectance and transmittance as base parameters. Images of the top and underside of the leaf are captured.

Robustness and Optimality of Light Harvesting in Cyanobacterial Photosystem I [PDF]
arXiv, 2002 As most biological species, photosynthetic lifeforms have evolved to function optimally, despite thermal disorder and with fault tolerance. It remains a challenge to understand how this is achieved. To address this challenge the function of the protein-pigment complex photosystem I (PSI) of the cyanobacterium Synechococcus elongatus is investigated ...

Silicate fertilization potentiates the nodule formation and symbiotic nitrogen fixation in soybean
Pesquisa Agropecuária Tropical, 2018 The application of silicon (Si) to the soil can increase the grain yield of the soybean crop by improving the nitrogen biological fixation, due to its beneficial effect on the Bradyrhizobium-soybean symbiosis.

A nondestructive method to estimate the chlorophyll content of Arabidopsis seedlings
Plant Methods, 2017 BackgroundChlorophyll content decreases in plants under stress conditions, therefore it is used commonly as an indicator of plant health. Arabidopsis thaliana offers a convenient and fast way to test physiological phenotypes of mutations and treatments ...

Light Absorption in Arctic Sea Ice: Chlorophyll and Black Carbon [PDF]
arXiv, 2017 Arctic sea ice extent has declined continuously for the past decade, owing partially to light absorption by black carbon (BC) and other impurities deposited on snow and the underlying pack. We present simulations for the contemporary period showing that the optical depth contributed by Arctic ice algal chlorophyll may be comparable during Boreal Spring
