Ecological stoichiometry influences phytoplankton alpha and beta diversity rather than the community stability in subtropical bay

open access: yesEcology and Evolution, Volume 12, Issue 9, September 2022., 2022
Seasonal change significantly shifted the phytoplankton community structure, and high diverse community was beneficial to maintaining the community stability. ;Ecological stoichiometry significantly affected the community diversity, and temperature, NO3‐, DIP and TDP were the main drivers of the community assemblage.

Multiobjective Optimization of Surface Roughness and Tool Wear in High‐Speed Milling of AA6061 by Machine Learning and NSGA‐II

open access: yesAdvances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
This work addresses the prediction and optimization of average surface roughness (Ra) and maximum flank wear (Vbmax) of 6061 aluminum alloy during high‐speed milling. The investigation was done using a DMU 50 CNC 5‐axis machine with Ultracut FX 6090 fluid. Four factors were examined: the table feed rate, cutting speed, depth of cut, and cutting length.

Anti‐Inflammatory Compounds from Vietnamese Piper bavinum

open access: yesJournal of Chemistry, Volume 2020, Issue 1, 2020., 2020
This study reports the anti‐inflammatory activity‐guided fractionation of the aerial part of Piper bavinum C. CD. (Piperaceae) that led to the isolation of eight secondary metabolites (1–8). The chemical structures of 1–8 were established mainly by NMR and mass spectra. Compound 5 was isolated from P. bavinum for the first time.

Core Design of a Small Pressurized Water Reactor with AP1000 Fuel Assembly Using SRAC and COBRA‐EN Codes

open access: yesScience and Technology of Nuclear Installations, Volume 2020, Issue 1, 2020., 2020
This paper presents the core design and performance characteristics of a 300 MWt small modular reactor (SMR) with fuel assemblies of the AP1000 reactor. Numerical calculations have been performed to evaluate a proper active core size and core loading pattern using the SRAC code system with the JENDL‐4.0 data library and the CORBRA‐EN code.
