Application of high optical technologies to determine the temperature field, ingredient composition and microstructure of the dispersed phase of combustion products of energy fuels [PDF]
E3S Web of Conferences, 2020 Application of high optical technologies for determining the temperature field, ingredient composition and microstructure of the dispersed phase of combustion products of power fuels is considered. The temperature of the combustion products is determined

Amplified Fiber-Optic Recirculating Delay Lines [PDF]
, 1994 Experimental and theoretical results on single- and double-amplified recirculating delay lines are presented. One of our aims is to emphasize their application as filters, showing a wide flexibility of design.

INVESTIGATION OF THE DAMPING CONSTANT OF FRAUNHOFER'S LINES IN SOLAR ATMOSPHERE
Odessa Astronomical Publications, 2017 To define chemical contents of elements in stars' atmospheres we need reliable data on their damping in spectral lines. We have found distinct expressions for damping constant with consideration of several mechanisms that in the expansion of spectral ...

Magnetic Field Information in the Near-ultraviolet Fe ii Lines of the CLASP2 Space Experiment
The Astrophysical Journal, 2023 We investigate theoretically the circular polarization signals induced by the Zeeman effect in the Fe ii lines of the 279.3–280.7 nm spectral range of the CLASP2 space experiment and their suitability to infer solar magnetic fields. To this end, we use a

Interhemispheric comparison of spectral width boundary as observed by the SuperDARN radars [PDF]
, 2003 International audiencePrevious studies have shown that dayside equatorward edge of coherent HF radar backscatter having broad Doppler spectral width is coincident with the equatorward edge of the cusp particle precipitation.

Stark Broadening of In III Lines in Astrophysical and Laboratory Plasma
Open Astronomy, 2011 In the deeper layers of hot stellar photospheres the Stark widths of spectral lines can be comparable and even larger than the thermal Doppler widths.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.

LAWS IN BEHAVIOUR OF NonLTE EFFECTS FOR THE NaI AND Mgl ATOMS FOR K - A STARS
Odessa Astronomical Publications, 2017 NonLTE calculations for the Nal and Mgl atoms were performed for model atmospheres of Tef= 4000 - 12000K. logg = 0.0 - 4.5, [NI/H] = 0.5- (-4). Departures from LTE result in strengthening the Nal spectral lines and weakening the Mgl ones.
