Dimethyl Carbonate as a Mobile-Phase Modifier for Normal-Phase and Hydrophilic Interaction Liquid Chromatography

open access: yesSeparations, 2023
We studied the use of dimethyl carbonate (DMC) as a non-toxic, aprotic modifier for hydrophilic liquid interaction chromatography (HILIC) and as a modifier for normal-phase liquid chromatography (LC). A comparison of ethyl acetate (EA) and DMC as organic

Thought, Policy and Practice with Regard to Urban Revitalization in the UK

open access: yesMaketingu Janaru, 2019
In British urban policy, sustainability has been viewed as the basic idea since the latter half of the 1990s, in addition to maintaining diversity. Based on these perspectives, various developments, including large-scale shopping centers, have been ...

Neurofilament-Immunoreactive Neurons Are Not Selectively Vulnerable in Alzheimer's Disease

open access: yesNeurobiology of Disease, 2001
Abnormal neurofilament protein distribution and phosphorylation contributes to the cytoskeletal pathology of Alzheimer's disease. Anatomical studies suggest that cortical neurons immunoreactive for nonphosphorylated 200-kDa neurofilament are most ...

Variation within laminae: Semi‐automated methods for quantifying leaf venation using phenoVein

open access: yesApplications in Plant Sciences, 2020
Premise Physiological processes may vary within leaf laminae; however, the accompanying heterogeneity in leaf venation is rarely investigated because its quantification can be time consuming.

Machine-Learning-Based Carbon Dioxide Concentration Prediction for Hybrid Vehicles

open access: yesSensors, 2023
The current understanding of CO2 emission concentrations in hybrid vehicles (HVs) is limited, due to the complexity of the constant changes in their power-train sources. This study aims to address this problem by examining the accuracy, speed and size of

Synthesis of substituted Z-styrenes by Hiyama-type coupling of oxasilacycloalkenes: application to the synthesis of a 1-benzoxocane

open access: yesBeilstein Journal of Organic Chemistry, 2017
Several Hiyama cross-coupling reactions of oxasilacycloalkenes and aryl iodides are described that produce trisubstituted Z-styrenes in moderate to excellent yields.

RgC3H Involves in the Biosynthesis of Allelopathic Phenolic Acids and Alters Their Release Amount in Rehmannia glutinosa Roots

open access: yesPlants, 2020
Rehmannia glutinosa production is affected by replanting disease, in which autotoxic harm to plants is mediated by endogenous phenolic acids as allelopathic compounds found in root exudates.

Impacts of food availability and pCO2 on planulation, juvenile survival, and calcification of the azooxanthellate scleractinian coral Balanophyllia elegans [PDF]

open access: yesBiogeosciences, 2013
Ocean acidification, the assimilation of atmospheric CO2 by the oceans that decreases the pH and CaCO3 saturation state (Ω) of seawater, is projected to have severe adverse consequences for calcifying organisms.

Antipodal Vivaldi Antenna for Water Pipe Sensor and Telemetry

open access: yesInternational Journal of Geophysics, 2012
An antipodal Vivaldi antenna operates simultaneously for telemetry and sensing when placed conformally onto PVC pipes. Good radiation efficiency is realised and the antenna impedance matching remains stable when a pipe is empty or contains water.
