Plant performance analysis of biofacades in a hot, arid Region of Qatar
( Springer Nature , 2022 , Article)Green walls are a traditional system that has been rediscovered for addressing and combating effects of climate change on the urban environment. The greening of walls is one of the sustainable techniques towards green ... -
Plant phenology and its relation to the cool semi-arid condition of Sana'a
( Qatar University , 1997 , Article)In the cool semi-arid highland areas of Sana'a a plant phenological study of forty two species revealed that there was one major outburst of plant emergence corresponding with the first period of the heavy rainfall which ... -
Plant Population Density Effects On Yield Of Sorghum Grown In A Dry-Land Farming System
( Qatar University , 1996 , Article)Plant population studies in arid regions are very sparse and not well documented. A prerequisite in growing a successful sorghum (Sorghum bicolor [L.] Moench) crop is to obtain an adequate plant population. The response ... -
Plant traits poorly predict winner and loser shrub species in a warming tundra biome
( Springer , 2023 , Article)Climate change is leading to species redistributions. In the tundra biome, shrubs are generally expanding, but not all tundra shrub species will benefit from warming. Winner and loser species, and the characteristics that ... -
Planting Date Effect On Growth Characters And Yield Of Sorghum Under A Dry Farming-System In An Arabian Gulf Environment
( Qatar University , 1996 , Article)Irrigated crop production in Qatar is a risky enterprise due to extreme weather conditions. Temperature is sufficiently warm to allow planting of grain sorghum [Sorghum bicolor (L.) Moench] from Aug through to Oct. Crops ... -
Plasma neurological biomarkers as a measure of neurotoxicity in pediatric dental general anesthesia: a prospective observational feasibility study
( Springer Science and Business Media Deutschland GmbH , 2024 , Article)Purpose: Neurotoxicity concerns have been raised over general anesthesia and sedation medication use in children. Such concerns are largely based on animal studies, historical anesthetic agents, and assessment tools, ... -
Plasmid-mediated colistin resistance encoded by mcr-1 gene in Escherichia coli co-carrying blaCTX-M-15 and blaNDM-1 genes in pediatric patients in Qatar
( Elsevier , 2020 , Other)Plasmid-mediated colistin resistance encoded by mcr-1 gene in Escherichia coli co-carrying blaCTX-M-15 and blaNDM-1 genes in pediatric patients in Qatar -
Plasmolysis-Inspired Nanoengineering of Functional Yolk-Shell Microspheres with Magnetic Core and Mesoporous Silica Shell
( American Chemical Society , 2017 , Article)Yolk-shell nanomaterials with a rattle-like structure have been considered ideal carriers and nanoreactors. Traditional methods to constructing yolk-shell nanostructures mainly rely on multistep sacrificial template strategy. ... -
Plasmonic and chiroplasmonic nanobiosensors based on gold nanoparticles
( Elsevier B.V. , 2020 , Article)Development of optical nanobiosensors has emerged as one of the most important bioresearch areas of interest over the past decades especially in the modern innovations in the design and utilization of sensing platforms. ... -
Plasmonic Catalysis for Energy Conversion-An Overview and Recent Trends
( Springer , 2022 , Article)Scientists are encouraged to produce clean and sustainable energies now that they are aware of the expiration of non-renewable fuels and their adverse impact on the ecology. In view of this, plasmonic catalysis opens a new ... -
Plasmonic gold nanoparticles: Optical manipulation, imaging, drug delivery and therapy
( Elsevier B.V. , 2019 , Article Review)Over the past two decades, the development of plasmonic nanoparticle (NPs), especially gold (Au) NPs, is being pursued more seriously in the medical fields such as imaging, drug delivery, and theranostic systems. However, ... -
Plasmonic Modulator Based on Fano Resonance
