Two-Dimensional Electronic Spectroscopy of Chlorophyll a: Solvent Dependent Spectral Evolution [PDF]

, 2015
The interaction of the monomeric chlorophyll Q-band electronic transition with solvents of differing physical-chemical properties is investigated through two-dimensional electronic spectroscopy (2DES). Chlorophyll constitutes the key chromophore molecule

Evaluating nitrogen uptake: Methods and applications for plant research

Applications in Plant Sciences, EarlyView.
Abstract Nitrogen is an essential nutrient for the growth and development of plants, aiding many physiological and biological functions. Due to the high demand for the nutrient, it is common for agricultural production systems to fertilize crop fields with large quantities of nitrogen.

Active reservoir management: a model solution [PDF]

, 1992
Steady-state procedures, of their very nature, cannot deal with dynamic situations. Statistical models require extensive calibration, and predictions often have to be made for environmental conditions which are often outside the original calibration ...

Spatial and temporal variability of biogenic isoprene emissions from a temperate estuary [PDF]

, 2012
[1] Isoprene is important for its atmospheric impacts and the ecophysiological benefits it affords to emitting organisms; however, isoprene emissions from marine systems remain vastly understudied compared to terrestrial systems.

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

Archaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.

Fluorescence bands and chlorophyll a forms

Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects, 1964
Abstract Fluorescence spectra were determined at temperatures between 20° and −196° for a number of photosynthetic organisms. Below −90° the single fluorescence maximum around 685 mμ was replaced by a system of three bands, at 686, 696 and 717–720 mμ in algal cells. Cooling usually resulted in a decrease of the 685-mμ band.

Experimenting with ecosystem interaction networks in search of threshold potentials in real-world marine ecosystems [PDF]

, 2014
Thresholds profoundly affect our understanding and management of ecosystem dynamics, but we have yet to develop practical techniques to assess the risk that thresholds will be crossed.

Bacterial Pigments as Potential Antitumor Agents Against Gastrointestinal Cancers: A Comprehensive Systematic Review

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Gastrointestinal cancers (GICs) constitute one of the leading causes of cancer‐related morbidity and mortality worldwide. Despite currently available therapeutic strategies, new approaches and procedures are needed for their prevention and treatment.

Design of experiments‐driven optimization of Porphyridium marinum cultivation: impact of operational variables on phycoerythrin and exopolysaccharide production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Among the Porphyridium genus, Porphyridium marinum exhibits the highest phycoerythrin (PE) content. In this study, the metabolic trade‐off between biomass, PE, and sulfated exopolysaccharide (EPS) production was assessed under varying nitrogen and sulfur availability, light intensity, residence time, and cultivation mode.
