Disabling barriers—Coping with accessibility of nature in Biosphere Reserves
People and Nature, EarlyView.Abstract Biosphere Reserves have the mandate to foster the relationship between people and nature, which can benefit people in a variety of ways, including both physical and mental health. With about 16% of the global population, people with disabilities are a significant group of people who, so far, have received limited attention for their needs in ...

Comparison of jet Mach number decay data with a correlation and jet spreading contours for a large variety of nozzles [PDF]
Small-scale circular, noncircular, single- and multi-element nozzles with flow areas as large as 122 sq cm were tested with cold airflow at exit Mach numbers from 0.28 to 1.15.

A Constant Trinitrotoluene Equivalence Fit for Blast Wave Position Versus Time Data
Propellants, Explosives, Pyrotechnics, EarlyView.ABSTRACT Accurately evaluating accidental or intentional detonation scenarios is essential to ensure their intended effectiveness and/or protect personnel and structures. These evaluations often rely on estimating critical blast effect parameters through reference models, which adapt to different scenarios via key constants.
