Spectroscopic analysis of N-intrashell transitions in Rb-like to Ni-like Yb ions.

Extreme ultraviolet spectra of highly-charged ytterbium ions produced in an electron beam ion trap at the National Institute of Standards and Technology were observed with a flat-field grazing incidence spectrometer in the wavelength region of about 4 nm-20 nm. The measured spectra were interpreted through detailed analysis by collisional-radiative modeling of the non-Maxwellian EBIT plasma. Seventy-nine new spectral lines due to intrashell (Δn = 0, n = 4) electric-dipole, magnetic-dipole, and electric-quadrupole transitions were identified in Rb-like Yb33+ through Ni-like Yb42+ ions. The effects of strong configuration interaction within the n = 4 complex on the measured spectra are discussed for a number of ionization stages.

Factors Affecting the Uptake of Institutional Delivery, Antenatal and Postnatal Care in Nawalparasi District, Nepal.

Background Maternal deaths and complications are highly preventable with good antenatal, postnatal and skilled care during childbirth. Inadequate information on the factors affecting these services could be barrier to a reduction of maternal deaths in lowincome countries. Objective To assess the uptake of antenatal, postnatal and skilled care during childbirth. Method A cross-sectional study was conducted in eight villages of Nawalparasi district in southern Nepal. A total of 447 women who had given birth within the preceding 24 months were recruited using multistage random sampling. Data were collected using a pre-tested semi-structured questionnaire. Chi-square tests were used to assess association between variables. Result Over 70% of women had gone for at least four antenatal care check-ups while only 14.3% had at least three postnatal check-ups in their last pregnancies. The proportion of institution delivery was 54%. Women's literacy was associated with the uptake of antenatal services (p=< 0.001), postnatal care (p=0.04) and institutional delivery (p=< 0.001). Knowledge of antenatal (p=< 0.001) and postnatal care was also associated with uptake of respective services (p=< 0.001). Conclusion The uptake and knowledge of antenatal care was much better than of postnatal care. Home delivery rates were still very high. A scaling-up of education and awarenessraising interventions in this community could help improve the uptake of maternal health services.

Measuring the difference in nuclear charge radius of Xe isotopes by EUV spectroscopy of highly charged Na-like ions.

The difference in the mean-square nuclear charge radius of xenon isotopes was measured utilizing a method based on extreme ultraviolet spectroscopy of highly charged Na-like ions. The isotope shift of the Na-like D1 (3s 2 S 1/2 - 3p 2 P 1/2) transition between the 124Xe and 136Xe isotopes was experimentally determined using the electron-beam ion-trap facility at the National Institute of Standards and Technology. The mass-shift and the field-shift coefficients were calculated with enhanced precision by the relativistic many-body perturbation theory and multiconfiguration Dirac-Hartree-Fock method. The mean-square nuclear charge radius difference was found to be δ〈r 2〉136,124 = 0.269(42) fm2. Our result has smaller uncertainty than previous experimental results and agrees with the literature values.

Exploration and innovation in addressing maternal, infant and neonatal mortality.

The Government of Nepal has been remarkably progressive in introducing innovative community-based maternal newborn and child health interventions in an effort to address the major causes of maternal and child mortality in the country. This article describes the introduction of innovative interventions, including a review of the landmark research that precipitated the discussion and provided evidence of practical feasibility, the acceptance of the intervention concept and validity, the approval process and the introduction and results from the pilot interventions. These interventions, which include the use of misoprostol to prevent post partum haemorrhage during homebirths, Morang Innovative Neonatal Intervention, gentamicin in Uniject and for the management of neonatal sepsis and newborn vitamin A supplementation, are in various stages and demonstrate the responsiveness of the Government to new approaches that address the major causes of maternal and child mortality.

Testing a scalable community-based approach to improve maternal and neonatal health in rural Nepal.

OBJECTIVE: The aim of the study was to determine the feasibility of improved maternal-neonatal care-seeking and household practices using an approach scalable under Nepal's primary health-care services. STUDY DESIGN: Impact was assessed by pre- and post-intervention surveys of women delivering within the previous 12 months. Each district sample comprised 30 clusters, each with 30 respondents. The intervention consisted primarily of community-based antenatal counseling and dispensing and an early postnatal home visit; most activities were carried out by community-based health volunteers. RESULT: There were notable improvements in most household practice and service utilization indicators, although results regarding care-seeking for danger signs were mixed. CONCLUSION: It is feasible in a Nepal setting to significantly improve utilization of maternal-neonatal services and household practices, using the resources available under the government primary health-care system. This has the potential to significantly reduce neonatal mortality.
