Analysis of Mono-, Di- and Oligosaccharides by CE Using a Two-Stage Derivatization Method and LIF Detection. [PDF]

open access: yes, 2009
A sensitive CE with LIF method has been developed for quantitative analysis of small carbohydrates. In this work, 17 carbohydrates including mono-, di- and oligosaccharides were simultaneously derivatized with 4-fluoro 7-nitrobenzo furazane (NBD-F) via ...

Aqueous humour concentrations of HB‐EGF, EGF and VEGF‐A and axial length in humans

open access: yesActa Ophthalmologica, Volume 103, Issue 8, Page 919-928, December 2025.
Abstract Purpose To investigate relationships between the intraocular concentrations of heparin‐binding epidermal growth factor (HB‐EGF), epidermal growth factor (EGF) and vascular endothelial growth factor A (VEGF‐A) in dependence on axial length in humans. Design Clinical interventional cohort study.

Polarization-resolved sensing with tilted fiber Bragg gratings: theory and limits of detection [PDF]

open access: yes, 2015
Polarization based sensing with tilted fiber Bragg grating (TFBG) sensors is analysed theoretically by two alternative approaches. The first method is based on tracking the grating transmission for two orthogonal states of linear polarized light that are

Antimicrobial prescribing guidelines for horses in Australia

open access: yesAustralian Veterinary Journal, Volume 103, Issue 12, Page 781-889, December 2025.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Quantitation of serum lipoproteins by electrophoresis on agarose gel: standardization in lipoprotein concentration units (mg/100 ml) by comparison with analytical ultracentrifugation

open access: yesJournal of Lipid Research, 1971
Lipoprotein electrophoresis on agarose gel has been modified to allow estimation of the absolute quantity of each fraction. The reproducibility of the method is illustrated by 12 determinations in a single day on serum from one normal subject: mean total

Method for Assessing the Fidelity of Optical Diffraction Tomography Reconstruction Methods

open access: yes, 2019
We use a spatial light modulator in a diffraction tomographic system to assess the accuracy of different refractive index reconstruction algorithms. Optical phase conjugation principles through complex media, allows us to quantify the error for different

Silicon rich nitride: a platform for controllable structural colors

open access: yesNanophotonics, Volume 14, Issue 23, Page 3911-3919, 02 November 2025.
Abstract High refractive index dielectric materials like silicon rich nitride (SRN) are critical for constructing advanced dielectric metasurfaces but are limited by transparency and complementary metal oxide semiconductor (CMOS) process compatibility.

Changes of ultrasound characteristics of mango juice during fruit ripening [PDF]

open access: yes, 2012
Attenuation and propagation velocity of ultrasound signals at 25 MHz were measured on clear mango juice samples using a pulse echo method. Ultrasound characteristics were determined with other physico-chemical characteristics on juice samples extracted ...
