Europium‐ and dysprosium‐modified strontium aluminate: A luminescent marker system for enhanced gunshot residue detection

Journal of Forensic Sciences, EarlyView.
Abstract Forensic ballistics is essential in analyzing evidence from firearm use in criminal investigations, with gunshot residue (GSR) detection providing key information about the firearm and shooting conditions. Traditional methods like spectroscopy and scanning electron microscopy (SEM) have limitations in sensitivity, cost, and accessibility ...

Multiple temperature model for the information preservation method and its application to nonequilibrium gas flows [PDF]

, 2011
The information preservation (IP) method has been successfully applied to various nonequilibrium gas flows. Comparing with the direct simulation Monte Carlo (DSMC) method, the IP method dramatically reduces the statistical scatter by preserving ...

Performance and Exhaust Emissions of a Gas-Turbine Engine Fueled with Biojet/Jet A-1 Blends for the Development of Aviation Biofuel in Tropical Regions

Energies, 2020
Biofuels as alternative fuels in today’s world are becoming increasingly important for the reduction of greenhouse gases. Here, we present and evaluate the potential of a new alternative fuel based on the conversion of medium-chain fatty acids to biojet (

Navigating the Flames: Comparative Analysis of Cremation Practices in the Roman and Early Medieval Periods at Gbely‐Kojatín (SK) and Přítluky (CZ)

Archaeometry, EarlyView.
ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Modeling nitrogen species from ammonia reciprocating engine combustion in temperature-equivalence ratio space

Applications in Energy and Combustion Science
This paper explores nitrogen species formation in temperature (T)-equivalence ratio (ϕ) space under internal combustion engine-relevant conditions using zero-dimensional modeling. The analysis reveals that N2O and NO are formed in a much larger region of

Tracking a Rangeland Fire With Infrasound Arrays

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We present the first infrasound analyses of a rangeland fire and demonstrate infrasound's potential in monitoring wildland fires. We recorded a prescribed fire in sagebrush steppe in cool, moist conditions, using eight infrasound arrays of diverse size (3–44 sensors, 10–200 m width) and distance (0–20 km), including four arrays inside the burn

Prescribed burning shows minor impacts on black pine needle terpenes and pine processionary moth larval survival

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Our results highlight that prescribed burning in sub‐Mediterranean pine forests does not affect their resistance to PPM in the short term, either positively or negatively, indicating that it can be implemented to reduce wildfire hazard without influencing forest susceptibility to future PPM outbreaks.

High temperature particle -to-metal interaction in a simulated gas turbine environment [PDF]

, 2002
An experimental study of the particle-to-metal interaction during high temperatures and velocity impact conditions is presented. A novel continuous erosion testing facility have been used to study the effect of particle and metal target temperatures ...

Effects of natural gas admission location and timing on performance and emissions characteristics of LPDF two-stroke engine at low load

Case Studies in Thermal Engineering
Low-pressure gas-admission marine two-stroke engines have significant potential for reducing emissions in the shipping industry. However, they exhibit poor combustion quality under low-load conditions, leading to lower thermal efficiency and high levels ...
