Drivers of summer oxygen depletion in the central North Sea [PDF]

open access: yes, 2016
In stratified shelf seas, oxygen depletion beneath the thermocline is a result of a greater rate of biological oxygen demand than the rate of supply of oxygenated water. Suitably equipped gliders are uniquely placed to observe both the supply through the

Development and Application of Organic Sonosensitizers in Cancer Therapy

open access: yesAggregate, EarlyView.
This review provides a comprehensive overview of organic sonosensitizers employed in cancer treatment, describing their underlying mechanisms and structure‐activity relationship in terms of sonodynamic therapy. The significance of nanotechnology and combination therapy with other oncological modalities (photothermal therapy, photodynamic therapy, etc.)

Active Whisker‐Inspired Food Material Surface Property Measurement Using Deep‐Learned Mechanosensor

open access: yesAdvanced Intelligent Systems, EarlyView.
Herein, a new application is proposed for an active whisker sensor that mimics the movement of rat whiskers. The whiskers, which are deformed by contact with an object, provide information about surface properties. It is shown that active whisker sensors can be useful in the food industry, and data identification is performed using deep learning ...

Pollution influence on bacterial abundance and chlorophyll-a concentration: case study at Idku Lagoon, Egypt

open access: yesScientia Marina, 2000
Idku lagoon is one of the northern delta lakes, connected with the Mediterranean Sea through Boughaz El Maadyah. It is subjected to industrial, domestic and agricultural pollution. Depending on collected data of water samples during one year of research,

Evaluating Rice Straw as a Substitute for Barley Straw in Inhibiting Algal Growth in Farm Ponds [PDF]

open access: yes, 2019
Algal blooms disrupt aquatic ecosystems and are more common in lakes, ponds, and rivers during the summer months due to nutrient pollution. Livestock production can contribute increased quantities of nutrients to water bodies from runoff of manure ...

Does the abiotic environment influence the distribution of flower and fruit colors?

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

Photochemistry beyond the red limit in chlorophyll f–containing photosystems

open access: yesScience, 2018
Lower-energy photons do the work, too Plants and cyanobacteria use chlorophyll-rich photosystem complexes to convert light energy into chemical energy. Some organisms have developed adaptations to take advantage of longer-wavelength photons.

Development of an empirical model for chlorophyll-a and Secchi Disk Depth estimation for a Pampean shallow lake (Argentina) [PDF]

open access: yes, 2017
Shallow Pampean lakes are located in the most productive plain of Argentina. They are highly variable in salinity, turbidity and surface area. Laguna Chascomús has been monitored as a representative example of them.
