Exploring the Effect of Production Conditions of Chlorella minutissima on Its Pharmaceutical Potential: A Natural Source for Bioactive Compounds

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, Chlorella minutissima UTEX 234‐1 was produced under 12.43 μmol of photons m−2 s−1 (from the side surface, I1), 23.29 μmol of photons m−2 s−1 (from the top surface, I2), and 62.14 μmol of photons m−2 s−1 (from the top surface, I3) in BG‐11 medium (B1).

Preliminary study on effects of different areas of reed type rice on water purification in young crab pond

open access: yes浙江大学学报. 农业与生命科学版, 2017
Due to limited capacity of self-purification of water in ponds, accumulation of feed residue and metabolites lead to endogenous, exogenous pollution, and eutrophication. Currently, physical, chemical and biological methods are used to purify aquacultural

Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior

open access: yesAdvanced Physics Research, EarlyView.
Diel vertical migration hides an unexpected twist: Phytoplankton quietly engineer their local pH landscape, splitting into behaviorally distinct sub‐groups which stay separated even in identical conditions. Circadian pH changes, occuring over the course of a day, reshape their gravitactic behavior and physiological functions in ways scientists have ...

A Multisensor Remote Sensing Approach to Archaeological Prospection: Integrating UAV and Google Earth Data in the Bayan Gol Valley, Mongolia

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This study investigates the effectiveness of drone‐based remote sensing and Google Earth satellite imagery for archaeological prospection in the Bayan Gol Valley, Central Mongolia. Utilizing a fixed‐wing unmanned aerial vehicle (UAV) equipped with RGB and multispectral sensors, we surveyed 655 ha to document Mongol‐period settlement structures

Physically Based Predictive Modelling of Archaeological Proxies Using Cropmarks

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Cropmarks, as archaeological proxies, offer a valuable means of detecting buried sites through remote sensing. Yet, the scalability of such methods across varied archaeological contexts remains underexplored, and AI‐based modelling approaches are still in early stages.

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

open access: yesArchaeological 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.

Observations of the aerosol particle number concentration in the marine boundary layer over the south-eastern Baltic Sea

open access: yesOceanologia, 2013
Continuous measurements of the aerosol particle number concentration (PNC)in the size range from 4.5 nm to 2 µm were performed at the Preila marine background site during 2008–2009.The concentration maxima in summer was twice the average (2650±50 cm-3 ...
