    AnnotationAnalyses for the NICER data indicate that there is no significant variation of compact star radii within the mass range of 1.4 to 2.0 solar masses. Yamamoto et al. [Phys. Rev. C 108, 035811 (2023)] concluded recently that “this feature cannot be reproduced by the hadronic matter due to the softening of the equation of state (EoS) by hyperon mixing, suggesting the possible existence of quark phases in neutron-star interiors.” Using a collection of 162 purely nucleonic, hyperonic, and quarkish EoSs from the CompOSE database and some other works, we verify that hyperons indeed lead to a significant difference in radii of stars of 1.4 and 2.0 solar masses, which diminishes in the presence of quarks. We compare the shapes of the mass-radius curves and show that hyperons and quarks in the neutron star cores prefer a particular curve shape with backbending. It is argued that the shape is controlled by the density dependence of the nuclear symmetry energy. We draw attention to the existence of a class of purely hadronic relativistic mean-field EoSs with scalar-field dependent hadron masses and coupling constants that satisfy the known constraints on the EoSs including the analyses of the new NICER data and the above requirement of insignificant variation of the neutron star radii.

    Annotation© 2016, Univerzitet u Travniku. All rights reserved.The study have presented findings from the field of condition and level of musculoskeletal system of women at the age of adolescence (n = 66, age = 18.1±1.2 years, height = 167.6±3.9cm, weight = 57.6±5.3kg) with intention to pain as manifestation of functional disorder. The level of women´ musculoskeletal system was diagnosed by doctor (specialist) during the September 2015 by standardized methods based on clinical medicine. The results have significantly confirmed that functional disorders in the field of women´ musculoskeletal system have been without organic, orthopedic and neurologic disorders. We have found out that there has been a significant relationship (p<0.05) between the pain in cervical area of spine and functional condition of m. trapezius pars descendens and m. levator scapulae. What is more, there has existed significant relation (p<0.05) between lumbal spine area and flexors of lumbar joint, as well as has shared pain in already mentioned area. The above findings have correlated (r, p<0.05) with motion stereotypes of posture in already mentioned areas.
