Laser produced plasma refractometry

open access: yesLaser and Particle Beams, 1990
A method of probing beam refraction is suggested for the investigation of laserproduced plasma with high density gradients. The refraction angle α of a probing ray as a function of ray impact parameter p is used as input data. Different experimental realizations of α(p) measurements are considered.

Clinical performance evaluation of total protein measurement by digital refractometry and characterization of non-protein solute interferences

open access: yesPractical Laboratory Medicine, 2016
Objectives: Refractometric methods to measure total protein (TP) in serum and plasma specimens have been replaced by automated biuret methods in virtually all routine clinical testing.

Calibrating evanescent-wave penetration depths for biological TIRF microscopy

open access: yes, 2019
Roughly half of a cells proteins are located at or near the plasma membrane. In this restricted space the cell senses its environment, signals to its neighbors and ex-changes cargo through exo- and endocytotic mechanisms.

New polymers for phase partitioning [PDF]

open access: yes
The synthesizing of several polyethylene glycols having crown ethers attached is reported. This work led to the identification of three new polymer types which promise to be more effective at selectively binding specific cell types. Work was completed on

Integrated optics refractometry: sensitivity in relation to spectral shifts [PDF]

open access: yes, 2013
A new variant of the Vernier-effect based sensor reported in ref. 1 is introduced. Both sensor types may show a huge index induced spectral shift. It will be shown in a poster presentation that with such sensors, as well as with surface plasmon based ...

The Refractive Index of Human Milk Serum: Natural Variations and Dependency on Macronutrient Concentrations

open access: yesFoods
The refractive index (RI) of human milk serum (also known as whey, milk soluble fraction or milk plasma) depends on the individual molecular species dissolved in the serum and their concentrations.

Use of clinic refractometer at farm as a tool to estimate the IgG content in goat colostrum

open access: yesJournal of Applied Animal Research, 2018
Refractometry has been proposed as a farm technique to estimate the IgG concentration in colostrum. In order to validate the method in goat colostrum using a clinical refractometer, 216 colostrum and milk samples were obtained from 54 dairy goats ...

MORPHOLOGICAL AND PHYSICO-CHEMICAL PROPERTIES OF ERYTHROCYTE CARRIERS INCAPULATED BY TERPINEINDOLICALK ALOIDS

open access: yesРазработка и регистрация лекарственных средств, 2019
Morphological and physico-chemical properties of erythrocytes encapsulated by terpenoindol alkaloids (TIA) by nephelometry and osmotic resistance of erythrocytes in a medium with low concentrations of sodium chloride have been studied.

Application of Cascaded TFBG for Wavelength-Shift-Based SRI Measurement with Reduced Polarization Cross-Sensitivity

open access: yesSensors
The wavelength shift in TFBG cladding resonance is a practical parameter due to its independence from power fluctuations coming from the light source or fiber bends.
