Unbounded solutions to some systems of conservation laws-split delta shock waves

open access: yesMatematički vesnik, 2002
The following Riemann problem in two variables \(u_t+(f_1(u)v+f_2(u)))_x=0\), \(v_t+(g_1(u)v+g_2(u)))_x=0\), with step functions as initial data, is considered in the case when admissible elementary solution does not exist. The author finds delta shock wave solution introducing ``left and right deltas''. We refer to [Math. Models Methods Appl. Sci. 12,

The prevalence of food insecurity and its relationship with wellbeing in a large, cross‐sectional study of children and young people in England

open access: yesJCPP Advances, EarlyView.
AbstractBackgroundWe aimed to assess the prevalence of food insecurity reported by children and young people in four areas of England in 2023 and examine its association with mental health and wellbeing.MethodsWe used data from the OxWell student survey, a large, diverse, cross‐sectional study of 38,430 students aged 8–19 years, conducted primarily in ...

Cordilleran Ice Sheet early deglaciation inferred from evolution of Late‐Pleistocene glacial Lake Dzulh Stun in east‐central British Columbia, Canada

open access: yesJournal of Quaternary Science, EarlyView.
Abstract We document the early decay of the Late‐Pleistocene Cordilleran Ice Sheet in the central portion of the Rocky and Cariboo Mountains and the Rocky Mountain Trench in east‐central British Columbia. Glacial lakes impounded at the eastern margin of the ice sheet occupied watersheds on the west flank of the central Rocky Mountains, leaving ...

Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...

A Shock‐Tube Study of the HCl + M →$\to $ H + Cl + M (M = Ar) Rate Constant Using HCl Laser Absorption Near 3.3 µm

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Hydrogen chlorine (HCl) is an important combustion intermediate during plastic (municipal waste) and composite propellant (aerospace) combustion, but the understanding of its high‐temperature chemistry is still evolving. In this study, the pyrolysis of 0.5% HCl in Ar was investigated behind reflected shock waves in a shock tube at temperatures
