Computational Fluid Dynamic‐Discrete Element Method Study of Biocarbon Injection in Electric Arc Furnaces Using Shrouding Jet Injectors

steel research international, EarlyView.
This study uses coupled computational fluid dynamic‐discrete element method (CFD–DEM) simulations to investigate biomass particle injection through a shrouded lance in electric arc furnaces (EAFs). It examines how biomass properties, feed rate, and lance design affect particle dispersion and delivery efficiency.

Metallic Axial Asymmetry in Dome‐Like Iron Porphyrins Boosts Advanced Oxidation Processes: Implication of Allosteric Effect of Heme Peroxidases

Small Structures, EarlyView.
A structure–activity relationship between dome‐deformation‐induced metallic axial asymmetry and catalytic efficiency in iron porphyrins was established, providing a molecular blueprint for designing high‐performance enzyme‐mimetic catalysts. The remarkable catalytic activity of heme enzymes originates from distinctive allosteric effects mediated by ...

Monitoring of historical structural materials with computed tomography

Structural Concrete, EarlyView.
Abstract Computed tomography (CT) is an excellent tool to solve certain engineering problems connected to material science (such as sulfate swelling, internal degradation due to freezing, and alkali silicate swelling) and to understand specific processes (frost peeling, acid action).

Analysis of Blasting Fragmentation Characteristics in Open-Pit Coal Mine

Meikuang Anquan, 2020
The distribution of blasting fragmentation in open pit coal mines is an important factor influencing the efficiency of resource mining. To clarify the distribution characteristics of coal rock mass under blasting, we use a Split Hopkinson Pressure Bar (SHPB) test system to perform specimen failure test under impact load, and use direct sieving method ...

Variation on Toxic and Inflammatory Potential of Coal Smoke of Different Sources From a Region With High Lung Cancer Risk

Environmental Toxicology, EarlyView.
ABSTRACT Excess lung cancer risk in Xuanwei and Fuyuan, China, has been attributed to household air pollution from use of a locally sourced smoky (bituminous) coal. However, the carcinogenic mechanisms remain unclear. Given the important role of inflammation in lung cancer development, this study compared the proinflammatory potentials of the ...

Otitis in pet guinea pigs: Causes, clinical signs, treatment and outcomes

Veterinary Record, EarlyView.
Abstract Background Otitis is a major disease impacting both pet guinea pigs and laboratory guinea pigs that are used as models in human otological studies. Methods Medical records from two veterinary clinics were retrospectively reviewed to identify guinea pigs diagnosed with computed tomography (CT)‐confirmed otitis between 2014 and 2023.

The Impact of Environmental Pollution and Climate Change on Allergic Rhinitis and Lung Diseases

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Environmental pollution and climate change seriously affect human health, leading to the onset and exacerbation of chronic respiratory diseases, such as allergic rhinitis and lung diseases. Over the past several decades, increasing air pollution and environmental exposure owing to global urbanization, industrialization, and rapid economic ...

[Energy requirements of miners engaged in open-pit coal mining].

Voprosy pitaniia, 1988
It has been found that according to the value of daily energy consumption the coal miners engaged in open-cast mining should be referred to group III-IV of work intensity. The determining component of daily energy consumption is energy consumption during the working period the value of which depends on the character of working activity and duration of ...

Divergent shifts in hydraulic versus carbon acquisition functional traits after wildfire in four Rocky Mountain tree species

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Climate change has increased the frequency and severity of drought and large wildfire events across western North America. Despite the increasing concurrence of drought and wildfire events and the importance of forests as a global carbon sink, the impacts of fire on ...
