Ocean color algorithm for remote sensing of chlorophyll [PDF]
An algorithm for the remote detection of chlorophyll a in the ocean was tested during a Nantucket Shoals experiment conducted by NASA. A set of Multichannel Ocean Color Sensor (MOCS) data selected from one flight for each of the two altitudes flown was ...

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT The quality and shelf life of extra virgin olive oil (EVOO) are pivotal to its marketability and consumer satisfaction. This study evaluated how pyropheophytin a (PPP) and 1,2‐diacylglycerols (DAGs) changed for different varieties of EVOO over a 24‐month storage period under varying temperature conditions (16°C, 18°C, and 20°C).

Phenotyping Plant Responses to Biotic Stress by Chlorophyll Fluorescence Imaging
Frontiers in Plant Science, 2019 Photosynthesis is a pivotal process in plant physiology, and its regulation plays an important role in plant defense against biotic stress. Interactions with pathogens and pests often cause alterations in the metabolism of sugars and sink/source ...

Strategic techniques for upgrading bio‐oil from fast pyrolysis: a critical review
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Pyrolysis has been the subject of extensive scientific research due to its potential application to various waste streams and byproducts from different production systems. One of its main products is the liquid fraction known as bio‐oil – a complex material composed of a wide variety of organic molecules and a significant water content.

Frequently asked questions about chlorophyll fluorescence, the sequel
Photosynthesis Research, 2016 Using chlorophyll (Chl) a fluorescence many aspects of the photosynthetic apparatus can be studied, both in vitro and, noninvasively, in vivo. Complementary techniques can help to interpret changes in the Chl a fluorescence kinetics.

The production of algae growing on gravel in a chalk-stream [PDF]
, 1976 Epilithic algae, ie that growing on the surface of stones, was studied as part of the work on the energy flow of the chalk-stream ecosystem, by the River Laboratory. The study area was on Bere Stream and 2 neighbouring streams.

Effects of water temperature on summer periphyton biomass in shallow lakes: a pan-European mesocosm experiment [PDF]
, 2015 Periphyton communities play an important role in shallow lakes and are controlled by direct forces such as temperature, light, nutrients, and invertebrate grazing, but also indirectly by planktivorous fish predation.
