Late hip subluxation due to a sequel of neonatal hip septic arthritis: A case report [Geç dönemde kalça yarı-çıkığına neden olan yenidoğan kalça septik artriti: Olgu sunumu]

Although there are major contributing factors causing developmental hip dysplasia, it is a well known fact that septic arthritis may cause hip subluxation, and developmental hip dysplasia. In this case report, a 28-day-old female patient whose ultrasonographic findings were found to be normal during neonatal period after detection of septic arthritis of the hip secondary to Candida spp., and who later developed hip subluxation of the affected hip is presented. It is emphasized that hip dysplasia, which is one of the rare complications of the septic arthritis, should be taken into consideration especially in patients with complaints of limping and yet the importance of close follow-up of patients with a history of septic arthritis for the risk of hip dysplasia and subluxation. © 2016, Logos Medical Publishing.

Pygmy and isovector giant dipole resonance in

The isovector electric giant dipole (E1) resonance (IVGDR) in well-deformed odd-proton $$^{175}$$Lu is investigated using the Translational and Galilean Invariant-Quasiparticle Phonon Nuclear Model (TGI-QPNM) for the first time. E1 transition probabilities, radiation widths, photoabsorption cross-sections, and integrated moments ($$\sigma _{-2}$$, $$\sigma _{-1}$$, $$\sigma _{0}$$, $$\sigma _{+1}$$ and $$\sigma _{+2}$$ ) have been calculated up to 25 MeV using this model. The photoabsorption cross-section results show that $$\varDelta$$K = 0 and $$\varDelta$$K $$=\pm$$1 modes split in $$^{175}$$Lu due to large quadrupole deformation (prolate). Thus, a two-peak shape occurs, which is consistent with the available experimental data. The centroid energies and the widths of these peaks are also reproduced well. Besides, special attention is paid to the low-energy tail of GDR, particularly around the neutron separation energy, where an enhancement of electric dipole strength has been observed for many nuclei in recent years

A theoretical analysis of the electromagnetic dipole response in odd-A thorium isotopes

We here present a theoretical analysis of electric and magnetic dipole (E1 and M1) resonances in the $$^{229-233}$$Th isotopes. In this study, the characteristic features of M1 and E1 excitations were calculated using the rotational invariant (RI-) and the translational Galilean invariant (TGI-) quasiparticle phonon nuclear models (QPNM), respectively.These models have been successfully applied to most rare-earth and actinide nuclei, with them yielding results that are consistent with the available experimental data.This study directly compares the TGI-QPNM results with experimental cross-section data (Oslo type; ($$\gamma$$,abs.)), and the model was found to reproduce the structural splitting of the E1 strength into two humps in the 8–20 MeV energy region.Furthermore, the study shows that the theoretical spectra of the $$^{231,233}$$Th isotopes, whose giant dipole resonance (GDR) has not yet been measured, almost overlaps with the experimental GDR spectrum of the neighboring $$^{232}$$Th nucleus.The predicted GDR parameters, such as peak energy, cross section, and width, are consistent with the experimental results. Our analysis also yields results that are similar to the corresponding parameters reported in the Oslo data for the PDR E1 ($$\omega _{\text {pyg}} \approx 7.2 \, \text {MeV}$$; $$\sigma _{\text {pyg}} \approx 10 \, \text {mb}$$) and spin-flip M1 ($$\omega _{\textit{M}1} \approx 6.67 \, \text {MeV}$$; $$\sigma _{\textit{M}1} \approx 4.36 \, \text {mb}$$) resonances

Investigation of the electric dipole (

E1 transition properties such as the reduced transition probabilities, excitation energies and photon–absorption cross-sections have been theoretically investigated for $$^{\mathrm {181}}$$Ta nucleus within the framework of Translational and Galileo Invariant-Quasiparticle Phonon Nuclear Model (TGI-QPNM). The model Hamiltonian includes the single-particle and the isovector dipole–dipole interaction terms along with the restoration forces. The strength of the isovector dipole–dipole interaction has been chosen to be $$\chi = 500/\hbox {A}^{\mathrm {5/3}} MeV \cdot fm^{-2}$$. Theoretical calculations show that in addition to the M1 excitations, there is considerable amount of E1 transitions especially between 2.6–3 MeV, which gives remarkable contribution to the fragmentation in the low-energy region of the dipole spectrum. Thus, the agreement between theory and experiment in terms of the fragmentation increases. Furthermore, the photon–absorption cross-sections in the Pigmy Dipole Resonance (PDR) region below the neutron separation energy ($$S_{n}$$) is compatible with experimental data
