Öğe Electric dipole oscillator strengths of boron(2008) Tekeli G.; Ateş Ş.; Çelik G.Electric dipole oscillator strengths for both individual and multiplet lines between some excited levels of atomic boron are calculated using the Weakest Bound Electron Potential Model Theory (WBEPMT). The Numerical Coulomb Approximation wave functions for expectation values of radii in all states and experimental ionization energies have been employed to determinate the parameters. The obtained results from this work agree very well with the accepted values taken from NIST, Multi-Configurational Hartree-Fock (MCHF) results and atomic line data. © TÜBİTAK.Öğe Energies, electric dipole (E1), quadrupole (E2), octupole (E3) and magnetic dipole (M1), quadrupole (M2) transition rates for Ca XII, Ti XIV, Cr XVI, Fe XVIII and Ni XX(Scientific Publishers, 2019) Çelik G.; Ateş Ş.; Nahar S.N.Energies, weighted oscillator strengths (gf), line strengths (S) and radiative rates (A) for allowed and forbidden transitions are presented for 2s2p62S1/2 ? 2s22p52P1/2, 2P3/2 and 2s22p52P1/2 ? 2s22p52P3/2 transitions in fluorine-like Ca XII (Z = 20), Ti XIV (Z = 22), Cr XVI (Z = 24), Fe XVIII (Z = 26) and Ni XX (Z = 28) ions. Moreover, the allowed electric dipole (E1) and the forbidden electric quadrupole (E2), octupole (E3), magnetic dipole (M1) and quadrupole (M2) transition rates for some transitions are obtained. The 2s22p5–2s 2p6-type transitions of F-like ions are prominent in high-temperature plasmas and are useful for diagnostics. The present results are obtained from configuration interaction atomic structure calculations using the code SUPERSTRUCTURE (SS) which includes relativistic effects in Breit–Pauli approximation. The comparison of the present energies with the available observed energies displayed very good agreement (< 1%). The presented excitation energy results have been compared with other detailed relativistic approaches such as Dirac–Fock, coupled cluster and configuration interaction for a few ionic states. © 2019, Indian Association for the Cultivation of Science.Öğe Results of routine urinalysis performed in first antenatal follow up and association between abnormal results and pregnancy outcomes [Erken gebelik haftasinda rutin olarak alinan tam i?drar tetkiklerinin sonuçlari ve anormal sonuçlarin gebeli?e etkileri](2012) Do?an N.U.; Çelik G.; Çelik Ç.; Genço?lu B.B.; Pekin A.; Seçilmiş Kerimo?lu Ö.Objective: To investigate routine urinalysis of pregnant women in first antenal follow-up and to assess association between abnormal urinalysis results and pregnancy outcomes. Material and Methods: Urinalysis, urine cultures and pregnancy outcomes and perinatal complications of 1882 pregnant women who admitted for first antenatal follow up to outpatient clinic were retrospectively analyzed. Pregnant women were grouped into two with respect to results of urinalysis (normal and abnormal group) and perinatal outcomes of these two groups were compared. Results: The rate of abnormal urinalysis was 28%. Microscopic hematuria was the most common abnormality with an incidence of 41% (219 patients) following proteinuria with rate of 12% (64 patients). There were 39 (21%) bacterial growth in urine cultures from 179 pregnant women with a suspicion of urinary tract infection. Women with abnormal urinalysis results were more likely to have adverse obstetric outcomes than women with normal results (p=0.031). There were eight cases of preterm labor, eight women with oligohydramnios. In follow-up four women were diagnosed as having preeclampsia and three of them had proteinuria in first visit. Conclusion: Urinalysis is simple and readily available test which is also a valuable tool diagnosing urogenital disorders such as asymptomatic bacteruria, proteinuria and hematuria. Pregnant women with early onset proteinuria is particularly at risk for preeclampsia and close follow-up for these patients are warrented. Copyright © 2012 by Türkiye Klinikleri.
