Calculation of the masses of the binary star HD 93205 by application of the theory of apsidal motion
(Wiley Blackwell Publishing, Inc, 2002-02)
We present a method to calculate masses for components of both eclipsing and non-eclipsing binary systems as long as their apsidal motion rates are available. The method is based on the fact that the equation that gives ...
Mass and p-factor of the type II cepheid OGLE-LMC-T2CEP-098 in a Binary System
(IOP Publishing, 2017)
We present the results of a study of the type II Cepheid (P-puls = 4.974 days) in the eclipsing binary system OGLELMC- T2CEP-098 (P-orb = 397.2 days). The Cepheid belongs to the peculiar W Vir group, for which the evolutionary ...
Medição instrumental de energia primária e secundária e sistematização da massa de dados gerada em sistema piloto eólico-solar
(2018-01-01)
The objective of this work is to determine the specificities of the variables of the primary and secondary energy analysis process, considering a system of electrical generation by a wind power plant and by a solar ...
Dispersed phase hold-up in a perforated rotating disc contactor (PRDC) using aqueous two-phase systems

VVVX near-IR photometry for 99 low-mass stars in the Gaia EDR3 Catalog of Nearby Stars
(2022)
Context. Red dwarf stars, which represent 75% of stars in the Milky Way, can be studied in great detail in the solar neighborhood, where the sample is more complete.Aims. We intend to better characterize red-dwarf candidates ...
RR Lyrae binary systems in the Galactic bulge
(2017)
The possibility of a direct mass measurement of RR Lyrae variable stars in binary systems has remained elusive for many years, due to the apparent paucity of such systems. Motivated by our recent success of finding a ...
The influence of lean mass in trabecular and cortical bone in juvenile onset systemic lupus erythematosus
(SAGE PUBLICATIONS LTD, 2008)
The aim of this study was to evaluate risk factors for low bone mineral density (BMD) and vertebral fractures, in juvenile systemic lupus (JSLE). Thirty-one consecutive patients with JSLE were compared with 31 gender- and ...
Autonomic modulation and its relation with body composition in swimmers
(Lippincott Williams & Wilkins, 2014-07-01)
This study compared autonomic modulation in swimmers and non-athletes in relation to body composition. A total of 28 athletes with a mean age of 19.7 +/- 2.9 years were evaluated who had at least 2 years of swimming training, ...
