Reducing the use of Fossil Carbon and Fuels to Defossilize the Electric Steelmaking Route: Evaluation of the Effects of Alternative C‐Bearing Materials and Hydrogen in the Electric Arc Furnace

steel research international, EarlyView.
The experiments and simulations demonstrate that, in general, alternative carbon sources can decrease fossil CO2 without adversely impacting EAF process and product. High plastics and tires ratios cause unsafe conditions and poor slag foaming. Hydrogen in EAF burners decreases CO2 but increases water vapor, which can raise the hydrogen content in ...

Do Asian Companies Bid Higher in Cross‐Border M&A? A Moderating Effect Analysis

Thunderbird International Business Review, EarlyView.
ABSTRACT This study examines whether Asian companies pay higher premiums in cross‐border mergers and acquisitions (M&A) and identifies the institutional factors driving this behavior. Grounded in the concept of Asian institutional logic—characterized by state coordination, relational governance, and long‐term strategic orientation—we argue that these ...

Soldabilidad en aceros inoxidables y aceros disimiles [PDF]

, 2011
La necesidad de unir aceros disímiles mediante procesos de soldadura por arco eléctrico es una práctica muy poco común, pero que, en algunos casos, se hace necesario por la complejidad de algunos equipos y máquinas (como calderas recuperadoras de calor, turbinas, intercambiadores de calor, etc.) requeridos en la industria.

Opium Cultivation Imperilling Endangered Species in Northern Laos

Animal Conservation, EarlyView.
To avoid government eradication efforts, farmers in northeastern Laos shifted opium cultivation deep into a national park, causing a > 1000% increase in protected forest cleared for the crop between 2018 and 2022. This displacement directly threatened endangered species like white‐cheeked gibbons, elephants, and dholes by causing a rise in hunting ...

Nature, origin, and phosphorylation potential of the phosphorus/sulfur‐bearing nanoscale multiphasic assemblages in the CM chondrites Murchison and Murray

Meteoritics &Planetary Science, EarlyView.
Abstract Carbonaceous chondrites contain phosphorus, whose speciation and thus history remain to be investigated. Phosphorus/sulfur‐bearing assemblages have been reported in carbonaceous CM chondrites, but there is no consensus about their exact compositions and origins.

A climate‐sensitive tropical urbanism under extreme heat†

Singapore Journal of Tropical Geography, EarlyView.
Tropical urban dwellers face twin climate challenges that impinge on their quality of life: climate overheating and the urban heat island (UHI). The latter superimposed on the former to lead to high levels of thermal discomfort, carbon and energy consequences.

Clinical, Behavioral and Neuroradiological Phenotype in an Italian Cohort of Patients With Xia Gibbs Syndrome: A Multicenter Cross‐Sectional Study and Systematic Literature Review

American Journal of Medical Genetics Part A, Volume 200, Issue 9, Page 2067-2079, September 2026.
ABSTRACT Heterozygous variants in the AHDC1 gene are associated with Xia Gibbs Syndrome (XGS), a genetic disorder with a highly variable phenotype. Cognitive impairment, motor delay, language delay, neonatal hypotonia, and sleep apnea are considered “cardinal” signs of the disease.
