Investigation of hydrogen-air ignition sensitized by nitric oxide and by nitrogen dioxide [PDF]
The sensitization of stoichiometric hydrogen-air ignition by NO, NO2 and a mixture of NO and NO2 was investigated behind reflected shock waves in a shock tube. Induction times were measured in pressure range 0.27 to 2.0 atm, temperature range 800 to 1500

Recycling of Mill Scale Into High‐Purity Iron Through Hydrogen‐Based Reduction
steel research international, EarlyView.Mill scale, an iron oxide–rich steel by‐product, is difficult to recycle due to impurities. This study evaluates hydrogen‐based direct reduction and hydrogen plasma smelting reduction as low‐carbon recycling routes. Impurity segregation limits reduction kinetics. Direct reduction achieves 92% conversion in 180 min, while plasma reduction reaches 91% in

Continuous Forest Fire Propagation in a Local Small World Network Model [PDF]
, 2013 This paper presents the development of a new continuous forest fire model implemented as a weighted local small-world network approach. This new approach was designed to simulate fire patterns in real, heterogeneous landscapes.

Development and Validation of a Next‐Generation Mechanistic Model of the Electric Arc Furnace
steel research international, EarlyView.This study presents a next‐generation mechanistic model of the electric arc furnace (EAF). It describes equations for all crucial processes appearing during the steel‐recycling process in an EAF, i.e., thermal, mass, and chemical. The model was parameterized and validated using industrial EAF data.

steel research international, EarlyView.The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.

Simulator test to study hot-flow problems related to a gas cooled reactor [PDF]
An advance study of materials, fuel injection, and hot flow problems related to the gas core nuclear rocket is reported. The first task was to test a previously constructed induction heated plasma GCNR simulator above 300 kW.

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 ...

With a Great Story Comes Great Responsibility: Role of Narrative in Leadership Development
New Directions for Student Leadership, Volume 2025, Issue 185, Page 81-87, Spring 2025.ABSTRACT Comic books reside uniquely within American culture. Historians have contended comics are more than just sequential artwork mixed with engaging stories, but rather, a framework by which the generations make sense of who they are. These stories are a reflection of cultural conscience; a lens through which we can view the world and a mirror ...
