Design Recommendations for Columns Made of Ultra-High-Performance Concrete and NiTi SMA Bars

open access: yesBuildings, 2023
The use of new materials in construction endows structures with better mechanical characteristics. The combination of ultra-high-performance concrete (UHPC) and nickel and titanium (NiTi) shape memory alloy (SMA) improves the behavior of building ...

Research on Dynamic Characteristics of Canopy and Column of Hydraulic Support under Impact Load

open access: yesEnergies, 2022
In the process of coal mining, the canopy and column play an important role in the safety support of hydraulic support. However, due to the complex and changeable coal seam conditions, the hydraulic support is significantly affected by the impact load ...

Behavior of precast reinforced concrete columns subjected to monotonic short-term loading

open access: yesFracture and Structural Integrity, 2019
This paper presents a case study on the behaviour of precast reinforced columns with non-conventional cross-section. An experimental program was developed to verify the serviceability and ultimate limit states of these columns, loaded with eccentric ...

Reanalysis of Copernicus Measurements on Interstellar Carbon Monoxide [PDF]

open access: yes, 2003
We used archival data acquired with the Copernicus satellite to reexamine CO column densities because self-consistent oscillator strengths are now available. Our focus is on lines of sight containing modest amounts of molecular species.

2019–20 Australian Bushfires and Anomalies in Carbon Monoxide Surface and Column Measurements

open access: yesAtmosphere, 2021
In Australia, bushfires are a natural part of the country’s landscape and essential for the regeneration of plant species; however, the 2019–20 bushfires were unprecedented in their extent and intensity.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
