Polymer Fractionation by Automated Laboratory System with Laser Optical Probe (L.A.F.P.)

open access: yesJournal of the Turkish Chemical Society Section B: Chemical Engineering, 2022
By examining the composition of copolymers and the distribution of their molecular weights, one can get an idea about their various properties. It is necessary to obtain homogeneous samples from fractions of different molecular weights of copolymers ...

Homogeneous fractional embeddings [PDF]

open access: yesJournal of Mathematical Physics, 2008
Fractional equations appear in the description of the dynamics of various physical systems. For Lagrangian systems, the embedding theory developed by Cresson [“Fractional embedding of differential operators and Lagrangian systems,” J. Math. Phys. 48, 033504 (2007)] provides a univocal way to obtain such equations, stemming from a least action principle.

Free vibration analysis of axially layered functionally graded short beams using experimental and finite element methods

open access: yesScience and Engineering of Composite Materials, 2016
Free vibration behavior of short beams made of axially layered functionally graded material (FGM) was investigated experimentally and numerically. Beams, which have gradation of the material properties in the axial direction, are fabricated by powder ...

Preferential attachment of Escherichia coli to different particle size fractions of an agricultural grassland soil. [PDF]

open access: yes, 2007
This study reports on the attachment preference of a faecally derived bacterium, Escherichia coli, to soil particles of defined size fractions. In a batch sorption experiment using a clay loam soil it was found that 35% of introduced E.

Quality evaluation of immunomodulatory polysaccharides from Agaricus bisporus by an integrated fingerprint technique

open access: yesFood Frontiers, 2023
Agaricus bisporus (A. bisporus) is a rich source of polysaccharides with medical and nutraceutical interests; however, the complex structure of A. bisporus polysaccharides (ABPs) poses a challenge to its quality control.

Synthesis of Glycogen Fractions by Heart Homogenates.

open access: yesExperimental Biology and Medicine, 1955
SummaryGlycolysis reduces both glycogen fractions of the rat heart at about the same rate for the first 5 minutes, regardless of the medium used for suspension of the tissue. In Krebs Phosphate Ringer's solution and in unoxygenated 5.4% glucose, the 2 glycogens drop to a low, but stable level.
