Classic Methodologies: Why They Still Matter

open access: yesNew Directions for Evaluation, EarlyView.
ABSTRACT While recognizing the importance of innovative, new approaches to evaluation, the guest editors and authors present this special issue of New Directions for Evaluation, urging evaluators to revisit established methodologies to address the growing complexity and ambiguity of today's wicked problems and indeed any problem they are commissioned ...

The emission of pollutants from ornamental shrubs during forest fires

open access: yesFire and Materials, EarlyView.
Abstract This study investigates the combustion behavior, emissions, and aerosol production of four plant species: Laurus nobilis, Cistus monspeliensis, Photinia fraseri, and Cupressus sempervirens. The Heat Release Rate (HRR) and Smoke Production Rate (SPR) were measured, revealing that Cupressus sempervirens had the highest HRR and longest flame ...

Shock-tube measurements of carbon to oxygen atom ratios for incipient soot formation with C2H2, C2H4 and C2H6 fuels [PDF]

open access: yes
The critical atomic carbon to oxygen ratios, Phi sub C, for incipient soot formation in shock heated acetylene, ethylene, ethane/oxygen/ argon mixtures was measured over the temperature range 2000 K to 2500 K for reactant partial pressures between 0.1 ...

Numerical Investigations of a Large Fire Exposure Crib Test—Presenting Different Pyrolysis Modelling Methodologies and Numerical Results

open access: yesFire and Materials, Volume 49, Issue 4, Page 371-387, June 2025.
ABSTRACT The need for numerical‐based approaches to investigate the fire behaviour in buildings with combustible components is growing due to the increasing use of timber by the construction industry to meet the ‘Climate Action Plan 2050’. This requires consideration of the complex kinetic processes that take place during the burning of the wood in the

Threshold Photoelectron Spectrum of 3,4‐Dimethylenecyclobutene

open access: yesHelvetica Chimica Acta, Volume 108, Issue 3, March 2025.
Abstract We report a study on the photoionization of the C6H6 isomer 3,4‐dimethylenecyclobutene, DMCB. The molecule is an intermediate in the formation of benzene from the propargyl radical self‐reaction, a suggested first step in the formation of polycyclic aromatic hydrocarbons and soot.
