Collective rotational bands at low excitation energy in 186Os: Vibrational and rotational degrees of freedom
(American Physical Society, 2022)Collective structures in 186Os have been investigated through the 186W(4He, 4n) 186Os reaction, at a beam energy of 48 MeV. The low-lying bands built on the excited 0+ 2 , 2+ 2 , and 4+ 3 states have been extended up ... -
The combat-tb workbench: Making powerful Mycobacterium tuberculosis bioinformatics accessible
(American Society for Microbiology, 2022)Whole-genome sequencing (WGS) is a powerful method for detecting drug resistance, genetic diversity, and transmission dynamics of Mycobacterium tuberculosis. Implementation of WGS in public health microbiology laboratories ... -
COMBAT-TB-NeoDB: Fostering tuberculosis research through integrative analysis using graph database technologies
(Oxford University Press, 2020)Tuberculosis (TB) is a significant global health threat, with onethird of the population infected with its causative agent Mycobacterium tuberculosis (M.tb). Globally, researchers have been responding with a plethora of ... -
Combined analysis of the low-energy enhancement of the gamma-strength function and the giant dipole resonance
(Springer, 2019)The nuclear dipole polarizability is mainly governed by the dynamics of the giant dipole resonance and has been investigated along with the effects of the low-energy enhancement of the photon strength function for nuclides ... -
Common bean as a potential crop for future food security: an overview of past, current and future contributions in genomics, transcriptomics, transgenics and proteomics
(Taylor & Francis Open Access, 2021)Common bean is an important legume crop having high quality protein, micronutrients, vitamins and antioxidants, which makes it a “grain of hope” for poor communities. Hence, a good number of breeding activities have been ... -
Communicating in designing an oral repository for rural African villages
(IIMC International Information Management Corporation, 2012)We describe designing an asynchronous, oral repository and sharing system that we intend to suit the needs and practices of rural residents in South Africa. We aim to enable users without access to personal computers to ... -
Community and marine conservation in South Africa: Are we still missing the mark?
(Frontiers Media, 2022)Marine Protected Areas (MPAs) in South Africa have a long history with currently 5% of the mainland’s ocean territory protected. The MPAs are celebrated and appreciated for their representative coverage of several habitat ... -
Community healthcare mesh network engineering in white space frequencies
(Institute of Electrical and Electronics Engineers, 2019)The transition from analog to digital television has availed new spectrum called white space, which can be used to boost the capacity of wireless networks on an opportunistic basis. One sector in which there is a need to ... -
Community-based solar power revenue alternative to improve sustainability of a rural wireless mesh network
(ACM, 2013)Given the needs for a clean and easy way to maintain and secure powering wireless networks in rural areas and to gen- erate revenue to guarantee the sustainability of its intended goals, an innovative approach to leverage ... -
Compaction of a zirconium metal–organic framework (UiO-66) for high density hydrogen storage applications
(Royal Society of Chemistry, 2018)We report a rare case whereby a metal–organic framework (MOF), namely UiO-66, is compacted at high pressure ( 700 MPa or 100 000 psi) resulting in densification and improved total volumetric hydrogen storage capacity, ... -
Comparative analysis of responses to field salinity stress in contrasting soybean accessions highlights NaCl exclusion in leaves as a key mechanism for salinity stress tolerance.
(JOURNAL OF OASIS AGRICULTURE AND SUSTAINABLE DEVELOPMENT, 2021)Salinity is one of the main limitations to legume productivity in many regions of the world and it is estimated that 50% of all arable land will become affected by salinity by 2050. The impact of field salinity on soybean ... -
A comparative analysis of contraceptive use in Africa: evidence from DHS
(SAGE Publications, 2016)The aim of this article is to show a comparative analysis of contraceptive use in areas of traditionally high fertility that have gone through profound changes. Data have been taken from the latest Demographic and Health ... -
Comparative analysis of human coronavirus-NL63 ORF3 protein homologues
(Academic Journals, 2009)It has been reported in some studies that the newly discovered human coronavirus NL-63 (HCoVNL63) is one of the most common coronaviruses associated with acute respiratory infections. HCoVNL63 was first isolated in 2004 ... -
Comparative analysis of testis and ovary transcriptomes in zebrafish by combining experimental and computational tools
(Wiley, 2004)Studies on the zebrafish model have contributed to our understanding of several important developmental processes, especially those that can be easily studied in the embryo. However, knowledge on late events such as gonad ... -
Comparative analysis of tests used to assess sperm chromatin integrity and DNA fragmentation
(Blackwell Publishing Ltd, 2021)Male infertility has a complex etiology, and many times, the cause is unknown. While routine semen analysis provides an overview of basic semen parameters, such as sperm concentration, motility, viability and morphology, ... -
Comparative analysis of the constitution and implementation of race/skin color field in health information systems: Brazil and South Africa
(Spinger, 2021)The inclusion of race/skin color in Health Information Systems makes it possible to measure health inequities. Brazil and South Africa correspond to countries marked by profound inequalities, multiracial constituted that ... -
Comparative analysis of the use of professional health providers by young mothers in developing countries: A new frontier for health education
