Microbiome enrichment from contaminated marine sediments unveils novel bacterial strains for petroleum hydrocarbon and heavy metal bioremediation
(Elsevier, 2023)Petroleum hydrocarbons and heavy metals are some of the most widespread contaminants affecting marine ecosystems, urgently needing effective and sustainable remediation solutions. Microbial-based bioremediation is gaining ... -
Effect of physical activity on coronary heart disease risk factors among firefighters: a scoping review protocol
(BMJ open, 2023)Introduction: Physical activity interventions have been used for various health conditions, including cardiovascular disease. However, the literature is still limited regarding the effect of physical activity on coronary ... -
Seed germination and seedling establishment in pistacia atlantica desf. and pistacia lentiscus l. under drought
(Russian Journal of Plant Physiology, 2023)The rehabilitation of degraded Mediterranean areas requires reintroduction of key-stone woody species. However, seed germination and seedling establishment for native species are poor. Germination behavior of Pistacia ... -
Statistical recovery of 21 cm visibilities and their power spectra with gaussian-constrained realizations and gibbs sampling
(The Astrophysical Journal Supplement Series, 2023)Radio interferometers designed to probe the 21 cm signal from Cosmic Dawn and the Epoch of Reionization must contend with systematic effects that make it difficult to achieve sufficient dynamic range to separate the 21 cm ... -
Measurement of the evolving galaxy luminosity and mass function using clustering-based redshift inference
(Monthly Notices of the Royal Astronomical Society, 2023)We develop a framework for using clustering-based redshift inference (cluster-z ) to measure the evolving galaxy luminosity function (GLF) and galaxy stellar mass function (GSMF) using Wide-field Infrared Survey Explorer ... -
Nitrogen fertilization increases the growth and nutritional quality of the forage legume, Calobota sericea – A preliminary investigation
(Elsevier, 2023)Calobota sericea is being evaluated as a forage for drought stressed areas. The nutritional quality of C. sericea from native populations are poor, and this is believed to be due to poor soil fertility. Therefore, a ... -
Figure rotation of dark haloes in cold dark matter simulations
(Oxford University Press, 2007)We investigate the figure rotation of dark matter haloes identified in cold dark matter (CDM) simulations.We find that when strict criteria are used to select suitable haloes for study, five of the 222 haloes identified ... -
Antibacterial and anti-inflammatory effects of Syzygium jambos L. (Alston) and isolated compounds on acne vulgaris
(BioMed Central, 2013)Acne vulgaris is a chronic skin disorder leading to inflammation as a result of the production of reactive oxygen species due to the active involvement of Propionibacterium acnes (P. acnes) in the infection site of the ... -
Enhanced anti-bacterial activity of biogenic silver nanoparticles synthesized from terminalia mantaly extracts
(Dove Press, 2019)The global increase in outbreaks and mortality rates associated with multidrug- resistant (MDR) bacteria is a major health concern and calls for alternative treatments. Natural-derived products have shown potential in ... -
Metal hydride beds-phase change materials: Dual mode thermal energy storage for medium-high temperature industrial waste heat recovery
(MDPI, 2019)Heat storage systems based on two-tank thermochemical heat storage are gaining momentum for their utilization in solar power plants or industrial waste heat recovery since they can e ciently store heat for future usage. ... -
Predicting amplification of mycn using cpg methylation biomarkers in neuroblastoma
(Future Science Group, 2021)Neuroblastoma is the most common extracranial solid tumor in childhood. Amplification of MYCN in neuroblastoma is a predictor of poor prognosis. Materials and methods: DNA methylation data from the TARGET data matrix were ... -
Landsat-8 and sentinel-2 based prediction of forest plantation c stock using spatially varying coefficient Bayesian hierarchical models
(MDPI, 2022)This study sought to establish the performance of Spatially Varying Coefficient (SVC) Bayesian Hierarchical models using Landsat-8, and Sentinel-2 derived auxiliary information in predicting plantation forest carbon (C) ... -
Unique aliphatic amidase from a psychrotrophic and haloalkaliphilic nesterenkonia isolate
(American Society for Microbiology, 2011)Nesterenkonia strain AN1 was isolated from a screening program for nitrile- and amide-hydrolyzing microorganisms in Antarctic desert soil samples. Strain AN1 showed significant 16S rRNA sequence identity to known members ... -
