Rapid prediction of Porphyra photosynthetic pigments based on colorimetric parameters
Frontiers in Sustainable Food SystemsPhotosynthetic pigments such as phycobiliproteins and chlorophyll a are important quality indicators of seaweeds. In this study, multivariate nonlinear regression (MNLR) models were developed and validated for the rapid determination of photosynthetic ...

Unlocking Li/Mg‐Based Photochemical Nitration Platforms for Anticancer Drug Discovery
Advanced Science, EarlyView.Two low‐toxicity light main‐group metal photochemical systems based on lithium and magnesium are constructed for selective C(sp2)‐H (di)nitration of anilines. The obtained dinitrated products exhibit anti‐HCC (hepatocellular carcinoma) and anti‐KYSE30 cell activities, holding promise as novel antitumor candidates.

Lower respiration in the littoral zone of a subtropical shallow lake
Frontiers in Microbiology, 2013 Macrophytes are important sources of DOC to littoral zones of lakes, but this DOC is believed to be mostly refractory to bacteria, leading to the hypothesis that bacterial metabolism is different in littoral and pelagic zones of a large subtropical ...

Photodecomposition of Chlorophylls and Chlorophyll Derivatives
Eiyo To Shokuryo, 1969 クロロフィル, クロロフィリン, フェオフィチンおよびクロロフィル誘導体の銅クロロフィル, 銅クロロフィリンナトリウム, 鉄クロロフィリンナトリウムの光分解, さらにクロロフィルaの光分解に対する水分, 遷移金属 (Fe2+, Fe3+), L-アスコルビン酸の影響を検討し, 次の結果をえた。1. クロロフィルは著しい光分解をうけ, とくにクロロフィルaはbに比較してその光分解度が大きい。2. クロロフィリンはクロロフィルaより光に対してはるかに安定であるが光分解をうける。とくに溶液の濃度が薄いほど光分解度が増大する。3. フェオフィチンは光に対してやや不安定で光分解をうける。4.

Is Precision Agriculture Technology Adoption Persistently Overestimated?
Agribusiness, EarlyView.ABSTRACT Precision agriculture is sometimes assumed to diffuse steadily over time, and industry planning frequently extrapolates early adoption trends forward. This study evaluates the accuracy of such expectations by comparing agricultural input dealers' forecasts of future service offerings with the actual levels of offerings that dealerships ...

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species
American Journal of Botany, EarlyView.Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.
