Effect of Spatial-Temporal Light Competition on Cotton Yield and Yield Distribution [PDF]

Agronomy, 2021
The photosynthetically active radiation (PAR) of crop canopy is highly related to yield formation, but how it relates to yield and yield distribution is not well understood.

Experimental Determination of Detector-Relevant Properties of ZnSe(Al,O) for Beta Spectroscopy [PDF]

Sensors
ZnSe-based scintillators are promising materials for compact beta spectroscopy, but the detector-relevant properties of ZnSe(Al,O) remain poorly documented and strongly dependent on dopant and defect structure.

Improving light yield measurements for low-yield scintillators

Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2019
Light power spectra are introduced as a new tool for relative light yield (LY) determinations. Light event spectra have commonly been used for this purpose. Theoretical background supporting this change is provided. It is shown that the derivative of a light power spectrum can provide a reliable LY measurement at levels as low as 2% of those for high ...

Casting light on the architecture of crop yield

Crop and Environment, 2022
Crop canopy architecture is a central component of yield. The arrangement of leaves in three-dimensional space defines the efficiency of absorption of radiation and its conversion into dry matter at the canopy level.

Effects of Applied Ratio of Nitrogen on the Light Environment in the Canopy and Growth, Development and Yield of Wheat When Intercropped

Frontiers in Plant Science, 2021
Changes in the light environment have an important effect on crop growth and yield. To clarify the effects of intercropping and the application of nitrogen on the yield of wheat and light within the crop canopy, the relationship between light and yield ...

Alkyl derivative of p-terphenyl as an activator of the plastic scintillators with n/γ-discrimination ability [PDF]

Ядерна фізика та енергетика, 2023
In order to increase the solubility of p-terphenyl molecules, their structure was modified with tert-butyl groups. A derivative of p-terphenyl 2,4,4′-tris-tert-butyl-1,1′:4′,1′-terphenyl was obtained.
