Retrospective studies of operating problems in air transport [PDF]
An epidemiological model for the study of human errors in aviation is presented. In this approach, retrospective data are used as the basis for formulation of hypotheses as to system factors which may have contributed to such errors.

Synthetic Lignin Oligomers: Analytical Techniques, Challenges, and Opportunities
ChemSusChem, EarlyView.The review begins by discussing lignin and its structural complexity, followed by challenges in elucidating depolymerization products and the analytical techniques used. It then focuses on the chemical structure of synthetic lignin oligomers, their synthesis mechanisms, and their significance in current science. Finally, scientific gaps are identified,

Boltzmann and the art of flying
, 2007 One of the less known facets of Ludwig Boltzmann was that of an advocate of Aviation, one of the most challenging technological problems of his times. Boltzmann followed closely the studies of pioneers like Otto Lilienthal in Berlin, and during a lecture

Sustainable Graphite and Jet Fuel from Biorefinery Residue
ChemSusChem, EarlyView.This study explores the novel conversion of bio‐oil from benzene‐toluene‐xylene (BTX) production into biographite and sustainable aviation fuel (SAF). By replicating synthetic graphite production through coking, calcination, and graphitization, the process yields high‐performance biographite suitable for lithium‐ion batteries.

A Survey of Phase Shifters for Microwave Phased Array Systems
International Journal of Circuit Theory and Applications, EarlyView.ABSTRACT Phased Array Systems (PASs) are extensively used in radar and telecommunication systems for diverse applications, including military surveillance and wireless broadband communication. Besides, they are becoming increasingly indispensable in modern applications such as multi‐function phased array radars for weather monitoring and aircraft ...

Deep Underground Science and Engineering, EarlyView.The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.
