Article Synopsis
- Smokeless powders (SLPs) consist of thermolabile and non-thermolabile compounds, and their analysis using GC-MS (Gas Chromatography-Mass Spectrometry) can be significantly influenced by the conditions during injection, but no systematic studies had been previously conducted.
- A recent study examined how the type of injector liner and the inlet temperature affect the chemical profiles of SLPs, revealing that both factors are crucial for obtaining reliable results, with the liner type having a notable impact.
- Interestingly, while higher temperatures led to the degradation of some thermolabile compounds like nitroglycerin, these extreme conditions actually resulted in more consistent measurements, suggesting that contrary to prior beliefs, harsher conditions might be more beneficial for profiling.
Kicking a person laying on the floor in the head is a crime whose forensic investigation could profit from additional microtraces capable of linking a suspected footwear, and by extension its owner, to the victim and their injuries. The transfer of hair fixatives (hair gel, hair wax, hair spray, hair foam, etc.) represents such a trace and was consequently practically evaluated throughout this study.

These changes also have indirect effects as survivors alter their within-group connections or move between groups. As group membership and network position may influence individual fitness, indirect effects may affect how individuals and populations recover from catastrophic events.

In turn, investors provide vital leverage on companies. Here, we report on our transdisciplinary science/business experience in applying the planetary boundaries framework (sensu Rockström et al.
