Correction factor for real-time determination of wood dust mass concentration by photometric method
Drvna Industrija, 2009 Samples of wood dust were collected in the working environment of wood machining processes for the purpose of determining correction factors for measuring mass concentration of wood dust by photometric method.

The Status of the Astrophysical Parameters of Upper Main Sequence Stars
AstronomyCalibrating the ages, masses, and radii of stars on the upper main sequence depends heavily on accurate measurements of the effective temperature (Teff) and surface gravity (logg).

The FEBS Journal, EarlyView.Using cryo‐EM combined with biochemical and genetic approaches, we mapped the interaction surface between NifL and NifA to gain insights into the regulation of nitrogen fixation genes in A. vinelandii. Our findings suggest that NifL, a homolog of histidine kinases lacking phosphorylation activity, evolved to act as a steric block of NifA activity ...

2MASS NIR photometry for 693 candidate globular clusters in M31 and the Revised Bologna Catalogue
, 2003 We have identified in the 2MASS database 693 known and candidate globular clusters in M31. The 2MASS J,H,K magnitudes of these objects have been transformed to the same homogeneous photometric system of existing near infrared photometry of M31 globulars,

International Journal of Cosmetic Science, EarlyView.Fragrance molecules release is influenced by skin type, with the effect varying depending on the specific fragrance compound. Two patterns of behaviour have been observed among fragrance molecules: the more volatile compounds whose evaporation increases with surface skin roughness and the less volatile and more lipophilic compounds influenced by skin ...

Interstellar extinction from photometric surveys: application to four high-latitude areas
Open Astronomy, 2018 Information on interstellar extinction and dust properties may be obtained from modern large photometric surveys data. Virtual Observatory facilities allow users to make a fast and correct cross-identification of objects from various surveys. It yields a
