Identification of single spectral lines in large spectroscopic surveys using UMLAUT: an Unsupervised Machine Learning Algorithm based on Unbiased Topology
(The Astrophysical Journal Supplement Series, 2021)The identification of an emission line is unambiguous when multiple spectral features are clearly visible in the same spectrum.However, in many cases, only one line is detected, making it difficult to correctly determine ... -
Identification of superior cellulase secretion phenotypes in haploids derived from natural Saccharomyces cerevisiae isolates
(Oxford University Press, 2019)The yeast Saccharomyces cerevisiae is considered an important host for consolidated bioprocessing and the production of high titres of recombinant cellulases is required for efficient hydrolysis of lignocellulosic substrates ... -
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 ... -
Identifying multiple periodicities in sparse photon event time series
(Oxford University Press, 2016)The data considered are event times (e.g. photon arrival times, or the occurrence of sharp pulses). The source is multiperiodic, or the data could be multiperiodic because several unresolved sources contribute to the time ... -
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 ... -
Immunoinformatics design of a novel epitope-based vaccine candidate against dengue virus
(Springer, 2021-10)Dengue poses a global health threat, which will persist without therapeutic intervention. Immunity induced by exposure to one serotype does not confer long-term protection against secondary infection with other serotypes ... -
Immunological changes during space travel: A ground-based evaluation of the impact of Neutron Dose Rate on Plasma Cytokine levels in human whole blood cultures
(Frontiers Media S.A., 2020)A better understanding of the combined impact of different space stressors on human health is urgently warranted, considering the upcoming long-duration missions beyond lower Earth orbit. Therefore, a growing number of ... -
The impact of active and passive thermal management on the energy storage efficiency of metal hydride pairs based heat storage
(MPDI, 2021)Two-tank metal hydride pairs have gained tremendous interest in thermal energy storage systems for concentrating solar power plants or industrial waste heat recovery. Generally, the system’s performance depends on selecting ... -
Impact of body composition analysis on male sexual function: A metabolic age study
(Frontiers Media, 2023)Metabolic Age (MetAge) and body composition analysis may reflect an individual’s metabolic status, which is believed to influence male sexual and gonadal functions. Although erectile dysfunction (ED) and hypogonadism ... -

(Frontiers, 2023)Metabolic Age (MetAge) and body composition analysis may reflect an individual’s metabolic status, which is believed to influence male sexual and gonadal functions. Although erectile dysfunction (ED) and hypogonadism ... -
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 COVID-19 on the male reproductive tract and fertility: A systematic review
(Informa UK Limited, trading as Taylor & FrancisGroup., 2021)Objective: The COVID-19 pandemic, caused by the acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), remains an ongoing public health challenge. Although males are affected slightly more than females, the impact of ... -
The impact of Covid-19 vaccines on male semen parameters: A retrospective cohort study
(University of the Western Cape, 2023)The emergence of SARS-CoV-2 and the subsequent COVID-19 pandemic necessitated the development of adequate vaccines. Despite vaccines being demonstrated to be safe and effective for preventing severe disease and death, ... -
The impact of detrital minerals on reservoir flow zones in the North Eastern Bredasdorp basin, South Africa, using core data
(MDPI, 2022)The present study uses core data to group reservoirs of a gas field in the Bredasdorp Basin offshore South Africa into flow zones. One hundred and sixty-eight core porosity and permeability data were used to establish ... -
