Sustainable agriculture through the enhancement of microbial biocontrol agents: Current challenges and new perspectives
(MDPI, 2023)The future of pesticide usage in agriculture is uncertain due to its unsustainability, adverse environmental impacts, and its association in enhanced phytopathogen resistance. Hence, this situation urges the development ... -
Analysis of the differentially expressed proteins and metabolic pathways of honeybush (cyclopia subternata) in response to water deficit stress
(MDPI, 2023)Honeybush (Cyclopia spp.) is a rich source of antioxidant properties and phenolic compounds. Water availability plays a crucial role in plant metabolic processes, and it contributes to overall quality. Thus, this study ... -
Whole-genome sequencing of African swine fever virus from wild boars in the Kaliningrad region reveals unique and distinguishing genomic mutations
(Frontiers Media, 2023)Since the first report of outbreaks of African swine fever (ASF) in Georgia in 2007, the disease has expanded into Europe, Russia, and Asia, spreading rapidly via contact with infected animals including domestic pigs and ... -
Galaxy–galaxy lensing in the voice deep survey
(EDP Sciences, 2022)The multi-band photometry of the VOICE imaging data, overlapping with 4.9 deg2 of the Chandra Deep Field South (CDFS) area, enables both shape measurement and photometric redshift estimation to be the two essential ... -
Impacts of the spatial configuration of built-up areas and urban vegetation on land surface temperature using spectral and local spatial autocorrelation indices
(Remote Sensing Letters, 2022)Understanding how the spatial configuration of land cover patterns of built-up areas and urban vegetation affect urban surface temperatures is crucial for improving the sustainability of cities as well as optimizing urban ... -
Increasing extracellular cellulase activity of the recombinant Saccharomyces cerevisiae by engineering cell wall-related proteins for improved consolidated processing of carbon neutral lignocellulosic biomass
(Elsevier, 2022)Sustainable bioproduction using carbon neutral feedstocks, especially lignocellulosic biomass, has attracted increasing attention due to concern over climate change and carbon reduction. Consolidated bioprocessing (CBP) of ... -
Correction: sibanda et al. application of drone technologies in surface water resources monitoring and assessment: a systematic review of progress, challenges, and opportunities in the global south. drones 2021, 5, 84

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 ... -
A synthesis review of vitamins involved in the fight against Covid-19
(Wiley, 2022)Although literature studies on earlier viruses such as the Severe Acute Respiratory Syndrome (SARS), the Middle East Respiratory Syndrome (MERS), and other similar viruses, in terms of treatment of coronavirus suggested ... -
Landuse and landcover change assessment in the Upper Runde sub-catchment, Zimbabwe and possible impacts on reservoir sedimentation
(Physics and Chemistry of the Earth, 2022)This work assesses land cover changes on the Upper Runde sub-catchment, Zimbabwe, and associated effects on sedimentation rates and risks. The model was implemented using the common Geographic Information Systems tools. ... -
Spatio–temporal variation of vegetation heterogeneity in groundwater dependent ecosystems within arid environments
(Ecological Informatics, 2022)Climate change, land cover change and the over–abstraction of groundwater threaten the existence of Groundwater-Dependent Ecosystems (GDE), despite these environments being regarded as biodiversity hotspots. The vegetation ... -
