Theoretical Analysis of Suspended Road Dust in Relation to Concrete Pavement Texture Characteristics

Atmosphere
Particulate matter (PM) originating from road dust is an increasing concern in urban air quality, particularly as non-exhaust emissions from tire–pavement interactions gain prominence.

Impact of optical wavelength on the reliability of photoplethysmography-based heart rate measurements outside of controlled laboratory environments

Current Issues in Sport Science
Introduction The effectiveness of heart rate (HR) measurements via photoplethysmography (PPG) depends on the wavelength of light used. Typical PPG sensors use green, red, or infrared light, each penetrating the skin to different depths (Ray et al ...

Optical Characterization of a New Facility for Materials Testing under Concentrated Wavelength-Filtered Solar Radiation Fluxes

Solar, 2023
The materials used to manufacture solar receivers for tower power plants must withstand high fluxes of concentrated solar radiation (from 0.1 to even 1.5 MWm−2) and operate at high operating temperatures (>800 °C).

Influence of Irradiance and Wavelength on the Antioxidant Activity and Carotenoids Accumulation in Muriellopsis sp. Isolated from the Antofagasta Coastal Desert

Molecules, 2022
Microalgae are a valuable natural resource for a variety of biocompounds such as carotenoids. The use of different light spectra and irradiance has been considered as a promising option to improve the production of these compounds.

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

FEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Research on infrared emission spectra of pulverized coal ash deposits [PDF]

FME Transactions, 2013
This paper deals with thermal radiation properties of ash deposits on a pulverized coal boiler of an electric power plant. Normal emittance spectra in the 2.5-25 μm interval, and total normal emittance, were measured on 2 kinds of ash layers of a mm ...

Physiological assessment of water deficit in soybean using midday leaf water potential and spectral features

Journal of Plant Interactions, 2019
Drought is one of the major abiotic stresses that limit soybean production worldwide. This study was conducted to determine whether soybean cultivars with divergent growth habits respond differently to drought stress at the vegetative growth stage ...
