Blood-gas vs. Central-Laboratory analyzers: interchangeability and reference intervals for sodium, potassium, glucose, lactate and hemoglobin

open access: yesHeliyon, 2021
Background: Blood-Gas Analyzers (BGAs) are commonly used in parallel with central laboratory analyzers (CLAs). Given the often-divergent results between BGAs and CLAs this study aims to: 1. Determine whether the measurements of potassium (K), sodium (Na),

Roche's Limits for Satellites [PDF]

open access: yesNature, 1922
THE notice in NATURE (July 15, p. 89) respecting Dr. Fountain's work on Roche's limit for satellites brings to my recollection some estimates which I made many years ago with respect to the stability of satellites moving close to the surface of Mars (Trans. Roy. Dub. Soc., 1897, vol. vi.).

Numerical Simulations of Collisional Cascades at the Roche Limits of White Dwarf Stars [PDF]

open access: yesThe Astrophysical Journal, 2017
AbstractWe consider the long-term collisional and dynamical evolution of solid material orbiting in a narrow annulus near the Roche limit of a white dwarf. With orbital velocities of 300 , systems of solids with initial eccentricitygenerate a collisional cascade where objects with radiiare ground to dust. This process converts 1–100 km asteroids into 1

SPECIFICATION OF LIMITS OF POSSIBLE EXISTENCE OF SATELLITES IN THE GRAVITATIONAL FIELD OF PLANETS

open access: yesOdessa Astronomical Publications, 2016
It is known that the satellites of the planets may exist in the area, which is bounded on one side by Rocha limit, on the other – Hill sphere. The article deals with the determination of the Rocha limits and Hill sphere of satellites of some planets in ...

Performance characteristics of a polymerase chain reaction-based assay for the detection of EGFR mutations in plasma cell-free DNA from patients with non-small cell lung cancer using cell-free DNA collection tubes.

open access: yesPLoS ONE
Survival rates in non-small cell lung cancer (NSCLC) are low. Detection of circulating tumor DNA in liquid biopsy (plasma) is increasingly used to identify targeted therapies for clinically actionable mutations, including EGFR mutations in NSCLC.
