“I just kept quiet”: Exploring equity in a service-learning programme
(International Association for Research on Service-Learning and Community Engagement (IARSLCE), 2016)Social justice underpins the sustainable development goal of health for all. In developing countries, social injustices are particularly severe and widespread, demanding critical and immediate attention. This article describes ... -
IC and RC band time-series observations of some bright ultracool dwarfs
(Oxford University Press, 2005)The results of more than 100 h of CCD photometric monitoring of 10 L dwarfs and two T dwarfs are presented. Reasonable evidence is shown for IC band variability in DENIS 0255−4700, DENIS 1705−0516 and 2M 2104−1037. ... -
ICT and information security perspectives in E-Health Systems
(Medwell Journals, 2010)This study examines issues pertinent to the rapidly evolving use of information as a currency of modern economies. Access to information has important benefits that can be achieved in many areas including, social-economic ... -
ICT4D and Local Access
(John Wiley & Sons, 2015)Local access in the context of regions in the global South continues to undergo transformation due to the growing ubiquity of mobile connectivity and the recent appearance of what have been termed “inverse” telecommunication ... -
Identification and characterization of microRNAs expressed in the African malaria vector Anopheles funestus life stages using high throughput sequencing
(BioMed Central, 2016)Background: Over the past several years, thousands of microRNAs (miRNAs) have been identified in the genomes of various insects through cloning and sequencing or even by computational prediction. However, the number of ... -
Identification and characterization of the Trichoplusia ni Single Capsid Nuclear Polyhedrosis Virus p10 gene
(Springer Verlag, 2000)The p10 gene was identified and characterized from the Trichoplusia ni single capsid nuclear polyhedrosis virus (TniSNPV). The p10 open reading frame (ORF) sequence was identified following sequencing of the ends of the ... -
Identification and profiling of salinity stress-responsive proteins in Sorghum bicolor seedlings
(Elsevier, 2012)Sorghum bicolor, a drought tolerant cereal crop, is not only an important food source in the semi arid/arid regions but also a potential model for studying and gaining a better understanding of the molecular mechanisms ... -
Identification of new respiratory viruses in the new millennium
(MDPI, 2015)The rapid advancement of molecular tools in the past 15 years has allowed for the retrospective discovery of several new respiratory viruses as well as the characterization of novel emergent strains. The inability to ... -
Identification, sequence analysis, and phylogeny of the immediate early gene 1 of the trichoplusia ni single nucleocapsid polyhedrosis virus
(Springer Verlag, 2001)Substantial research has been conducted on the immediate early 1 (ie-1) genes from the prototype baculovirus Autographa californica multicapsid nuclear polyhedrosis virus (AcMNPV) and the Orgyia pseudotsugata multicapsid ... -
Identifying global priorities for the conservation of vipers
(Elsevier, 2016)Vipers are among the most misunderstood and persecuted animals. They occupy most terrestrial ecosystems around the world, often at high population densities. However, certain aspects of their biology (e.g., low fecundity ... -
Imino-phospine palladium (II) and platinum (II) complexes: Synthesis, molecular structures and evaluation as antitumor agents
(Elsevier, 2013)The imino-phosphine ligands L1 and L2 were prepared via condensation reaction of 2-(diphenylphosphino) benzaldehyde with substituted anilines and obtained in very good yields. An equimolar reaction of L1 and L2 with ... -
Imino-quinolyl palladium(II) and platinum(II) complexes: synthesis, characterization, molecular structures and cytotoxic effect
(Elsevier, 2013)Imino-quinolyl ligands L1-L5 were synthesized by condensation reactions and obtained in good yields. Reactions of the ligands with either PdCl2(cod) or K2[PtCl4] gave the corresponding palladium(II) and platinum(II) complexes ... -
Impact of climate change and anthropogenic activities on renewable coastal resources and biodiversity in Nigeria
(Academic Journals, 2012)Climates related disaster is greatly human induced warming, leading to substantial fluctuations in earth temperature which is currently a global issue of environmental concern. Human proximity and pressure in and around ... -
The impact of ICT Investments on human development: a regression splines analysis
(Taylor & Francis, 2013)Despite the worldwide growth in investments in information and communication technology (JCT), few studies have investigated the complex interactions between components of JCT investments and different dimensions of human ... -
The impact of male overweight on semen quality and outcome of assisted reproduction
(Medknow Publications, 2014)The impact of obesity on male reproductive health remains a contested topic as evidence is inconclusive and inconsistent. Even more debatable is the effect of male obesity in assisted reproduction. In the manuscript, ... -
The impact of sperm DNA damage in assisted conception and beyond: recent advances in diagnosis and treatment
(Elsevier, 2013)Sperm DNA damage is a useful biomarker for male infertility diagnosis and prediction of assisted reproduction outcomes. It is associated with reduced fertilization rates, embryo quality and pregnancy rates, and higher ... -
Implicit-explicit predictor-corrector methods combined with improved spectral methods for pricing European style vanilla and exotic options
(Kent State University, 2013)In this paper we present a robust numerical method to solve several types of European style option pricing problems. The governing equations are described by variants of Black-Scholes partial differential equations (BS-PDEs) ... -
Improved Hand-Tracking Framework with a Recovery Mechanism
(Telkom, 2013)Abstract−Hand-tracking is fundamental to translating sign language to a spoken language. Accurate and reliable sign language translation depends on effective and accurate hand-tracking. This paper proposes an improved ... -
Improved SAAO–2MASS photometry transformations
(Oxford University Press, 2007)Near-infrared photometry of 599 stars is used to calculate transformations from the South African Astronomical Observatory (SAAO) JHK system to the Two-Micron All-Sky Survey (2MASS) JHKS system. Both several-term formal ... -
Improving maternal and reproductive health in Ethiopia
(Sage Publications, 2017)This study aimed to examine the relationship between maternal health and good quality of life in an attempt to understand the years between 2005 and 2011. Data from the Ethiopia Demographic and Health Surveys 2005 and 2011 ...
