Evaluation of the Mechanical Properties of Lightweight Foamed Concrete at Varying Elevated Temperatures

open access: yesFire, 2023
Lightweight foamed concrete (LFC) made from cementitious materials with air pores entrapped in the matrix by mechanically entrained foam in the mortar slurry has several economic and environmental benefits.

Resilient Event-Triggered Load Frequency Control for Multi-Area Power System With Wind Power Integrated Considering Packet Losses

open access: yesIEEE Access, 2021
The congest in an open communication system may cause the failure of the load frequency control (LFC) scheme in the power system. Furthermore, the increase of wind power penetration degrades the stability of the LFC scheme.

Space-time laser instabilities in homogeneously broadened dense media [PDF]

open access: yes, 2003
We investigate the space-time dynamics of a homogeneously broadened single-mode laser when local field correction (LFC) is taken into account. We demonstrate that the Maxwell-Bloch equations modified by LFC admit travelling-wave solutions, as when LFC is

On the utility of RNA sample pooling to optimize cost and statistical power in RNA sequencing experiments [PDF]

open access: yes, 2020
Background: In gene expression studies, RNA sample pooling is sometimes considered because of budget constraints or lack of sufficient input material. Using microarray technology, RNA sample pooling strategies have been reported to optimize both the cost

The influence of fly ash and foam contents on the properties of lightweight foamed concrete

open access: yesVietnam Journal of Science, Technology and Engineering, 2022
Due to rapid industrialization and modernization, a large number of both fly ash (FA) and ground granulated blast furnace slag (GGBFS), both by-products from thermal power plants and steel factories, are increasing day by day.

Effect of a high forage: Concentrate ratio on milk yield, blood parameters and oxidative status in lactating cows [PDF]

open access: yes, 2020
A feeding strategy that requires a forage: concentrate ratio equal to 70: 30, with at least five different herbs in the forage and the use of silages prohibited, has recently been introduced in Italy.

The Importance of Moisture Content to the Emissivity of Ceramic Bricks

open access: yesProceedings, 2019
Emissivity is a key parameter if one intends to use quantitative thermography. The importance of temperature, surface characteristics, wavelength and the direction of the emitted radiation in the emissivity is well documented in the literature.
