Confidence intervals for the correlation between the gamma-ray burst peak energy and the associated supernova peak brightness
(Oxford University Press, 2009)A strong correlation between the gamma-ray burster peak energy and the peak luminosity of the associated supernova was discovered by Li for four GRBs. Despite the fact that the formal significance level of the correlation ... -
Control of airborne microbes in a poultry setting using Dioxy MP 14
(FACTA-FUNDACIO ARNCO CIENCIA TECNOLOGIA AVICOLAS, 2015)In this study, Dioxy MP 14, a locally developed form of chlorine dioxide, was tested in a commercial chicken pen to determine its effectiveness as an airborne environmental sanitizing agent. The biocide was introduced via ... -
Correcting CCD photometry of stars for seeing effects
(Oxford Univeristy Press, 2009)Systematic variability in stellarmagnitudes, as derived from profile fitting to CCD images,may in some instances be due to variable seeing. It is suggested that this happens in cases where the stars are unresolved pairs, ... -
Correlates of antenatal and postnatal care among tribal women in India
(Kamla-Raj Enterprises, 2012)It is well established that those women who undergo full antenatal care check-up and give birth in a medical institution or whose delivery is attended by trained paramedical persons promotes child survival and reduces ... -
Correlates of early sexual debut and its associated STI/HIV risk factors among sexually active youths in Malawi
(SAGE Publications, 2017)This study explores the correlates of early sexual debut and risk factors of sexually transmitted infections (STIs) among the youth in Malawi. Data was obtained from the Malawi Demographic Health Survey 2010. Out of a ... -
Correlates of gender characteristics, health and empowerment of women in Ethiopia
(BMC, 2015)The low status of women prevents them from recognizing and voicing their concerns about health needs. This study aimed to examine the relationship between gender characteristics, health and empowerment of women in an ... -
Correlates of infant and child mortality in Ethiopia 2005
(University of the Western Cape, 2010)INTRODUCTION: Risk of mortality prevails for children with shorter birth interval since their mothers are likely to have poor health. AIM: The aim of the study is to determine the indirect estimation of infant and child ... -
The detailed forms of the LMC Cepheid PL and PLC relations
(Oxford University Press, 2007)Possible deviations from linearity of the Large Magellanic Cloud Cepheid period–luminosity (PL) and period–luminosity–colour (PLC) relations are investigated. Two data sets are studied, respectively from the Optical ... -
Detection of an increasing orbital period in the subdwarf B eclipsing system NSVS 14256825
(Oxford University Press, 2012)New timings of eclipses made in 2010 and 2011 are presented for the hot subdwarf B (sdB) eclipsing binary NSVS 14256825. Composed of an sdB star and a much cooler companion, with a period near 0.1104 days, this system ... -
A detection threshold in the amplitude spectra calculated from Kepler data obtained during K2 mission.
(Oxford University Press, 2015)We present our analysis of simulated data in order to derive a detection threshold which can be used in the pre-whitening process of amplitude spectra. In case of ground-based data of pulsating stars, this threshold is ... -
Determinants of women’s preferred and actual abortion provision locations in Nigeri
(Springer, 2021)Background: Unsafe abortion remains a leading cause of maternal mortality globally. Many factors can infuence women’s decisions around where to seek abortion care; however, little research has been done on abortion care ... -
Does seasonality and stochastic cycles affect output growth in Nigeria? Lessons for development planning
(International Foundation for Research and Development (IFRD), 2016)This paper examines the seasonality and stochastic cycle associated with GDP growth in Nigeria using two measures of filter. Our findings include, that the Christiano & Fitzgerald (2003) filter removed low-periodicity ... -
The effect of weak lensing on distance estimates from supernovae
(American Astronomical Society, 2013)Using a sample of 608 Type Ia supernovae from the SDSS-II and BOSS surveys, combined with a sample of foreground galaxies from SDSS-II, we estimate the weak lensing convergence for each supernova line of sight. We find ... -
Epidemiological analysis of spatially misaligned data: a case of highly pathogenic avian influenza virus outbreak in Nigeria
(Cambridge University Press, 2013)This research is focused on the epidemiological analysis of the transmission of the highly pathogenic avian influenza (HPAI) H5N1 virus outbreak in Nigeria. The data included 145 outbreaks together with the locations of ... -
Epidemiology, clinical characteristics and severity of gradual onset injuries in recreational road cyclists: A cross-sectional study in 21,824 cyclists - SAFER XIII
(Elsevier, 2020)Objectives: Prevalence, clinical characteristics and severity of gradual onset injuries (GOIs) in cyclists are poorly documented. We determine the prevalence, anatomical regions/sites affected and severity of GOIs among ... -
Estimation of the coherence time of stochastic oscillations from modest samples
(Oxford University Press, 2012)‘Quasi-periodic’ or ‘solar-like’ oscillations can be described by three parameters – a characteristic frequency, a coherence time (or ‘quality factor’) and the variance of the random driving process. This paper is concerned ... -
Evidence for rapid evolution of periodic variations in an ultracool dwarf
(Oxford University Press, 2006)The results of three short photometric monitoring runs on the L0 dwarf 2MASS J06050196−2342270, during three consecutive nights, are presented. The observations show the persistent presence of a 2.4-h period, with an IC ... -
Examining inequality of opportunity in the use of maternal and reproductive health interventions in Sierra Leone
(Oxford University Press, 2020)Poor countries, such as Sierra Leone, often have poor health outcomes, whereby the majority of the population cannot access lifesaving health services. Access to, and use of, maternal and reproductive health services is ... -
An exploratory look at associated factors of poverty on educational attainment in Africa and in-depth multilevel modelling for Namibia.
(BER, 2013)This study examines several indicator variables related to education and poverty in Africa from the Demographic and Health Surveys (DHS). Many have described income and education as one of the fundamental determinants ... -
An extensive search for rapid optical variability in ultracool dwarfs
(Oxford University Press, 2013)In this paper, a summary of optical time-series photometry of 125 ultracool dwarfs is given. The observing strategy was to monitor each object continuously for 2–3 h in order to ascertain whether itwas rapidly variable. ...
