Radiation dimming induced modifications in radiation utilization of wheat (Triticumaestivum) crop

open access: yesJournal of Agrometeorology, 2020
Global dimming has many environmental and climatic implications. India has also experienced a steady and continuous radiation dimming since 1960s due to increasing load of dust and aerosol in the atmosphere.

Efficient sound radiation using a bandgap structure [PDF]

open access: yesApplied Physics Letters, 2019
This work reports on the use of bandgaps to increase the efficiency of sound radiation employing defect modes on a phononic crystal (PnC). A PnC consisting of a 2D array of studs on an aluminum plate is considered, and a defect is created by removing four studs.

A Review of Modeled Water Use Efficiency of Highly Productive Perennial Grasses Useful for Bioenergy

open access: yesAgronomy, 2020
Whole plant productivity is obviously the ultimate product of leaf photosynthesis and this has led to numerous efforts to relate the two. However, often with perennial grasses, plant productivity is more sink-limited than source-limited, causing the ...

Intercepted Photosynthetically Active Radiation (PAR) and Spatial and Temporal Distribution of Transmitted PAR under High-Density and Super High-Density Olive Orchards

open access: yesAgriculture, 2021
We quantified the photosynthetically active radiation (PAR) interception in a high-density (HD) and a super high-density (SHD) or hedgerow olive system, by measuring the PAR transmitted under the canopy along transects at increasing distance from the ...

Sorghum dwarfing genes can affect radiation capture and radiation use efficiency [PDF]

open access: yesField Crops Research, 2013
Presence of the dw3 sorghum dwarfing gene had negative effects on grain yield in some genetic backgrounds and environments. In a previous study we showed that this was due to a significant reduction in shoot biomass (mainly via reduced stem mass), which in turn negatively affected grain size. The current study examines whether shoot biomass was reduced

Water and radiation use efficiency in different developmental stages in four bread wheat cultivars under moisture stress conditions [PDF]

open access: yesDesert, 2007
This research was conducted in Toroq Experimental field station, Mashhad, Iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. Moisture stress treatments (

Diurnal and Seasonal Variations of Photosynthetic Energy Conversion Efficiency of Field Grown Wheat

open access: yesFrontiers in Plant Science, 2022
Improving canopy photosynthetic light use efficiency and energy conversion efficiency (εc) is a major option to increase crop yield potential. However, so far, the diurnal and seasonal variations of canopy light use efficiency (LUE) and εc are largely ...

Optimising radio coverage for wireless media servers [PDF]

open access: yes, 2010
A three element patch antenna array is designed for a 2×3 802.11n wireless home media server application for highdefinition video streaming at 2.4GHz. An efficiency comparison shows that the use of the RT/Duroid substrate results in a 3dB improvement in ...
