Kinetic Compensation of Barrel Launch Under High‐Speed Solid‐Phase Particulate Impacts

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT An accurate launch‐dynamics computational method is critical for barrel weapon service life assessment and multiphase physics field refinement. Given the lack of studies on the solid‐phase buildup behavior at the projectile base, this paper provides an improved method for calculating the launching dynamics under high pressure and high speed ...

An Optimum Organisation [PDF]

open access: yes, 1998
YesThe Ad Hoc Group (AHG) of the States Parties to the Biological and Toxin Weapons Convention (BTWC) have touched from time to time on the question of the organisation needed to implement the legally binding instrument being negotiated to strengthen ...

Deciphering the soybean root rot pathogen Phytophthora sojae: Signaling pathways, transcriptional regulation, and effector biology

open access: yesNew Plant Protection, EarlyView.
This review highlights how Phytophthora sojae utilizes unconventional lineage‐specific signaling networks, including unique G protein‐coupled receptor fusions, expanded kinases, and rapidly evolving effectors, to infect soybeans. Understanding these divergent molecular paradigms reveals critical vulnerabilities in this destructive pathogen, offering ...

Characterization of Ultrafast Decomposition Dynamics in Nitrate Esters

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Ignition of energetic materials initiates chemical reactions on atomic length scales within femtoseconds, making these reactions difficult to investigate experimentally. The technique of femtosecond time‐resolved mass spectrometry (FTRMS) can capture molecular rearrangement and bond‐breaking events in isolated molecules with sub‐50 femtosecond

Konvencija o zabrani kemijskoj oružja i uloga inženjera i znanstvenika [PDF]

open access: yes, 2010
Chemical weapons, like all military technology, are associated with activities of scientists and engineers. However, chemical weapons differ from any other military technology because they were invented, and their first mass use directly developed by ...

Constructing Difference: Maternal Boundary‐Work in Science‐Based and Natural Mom Groups on Facebook

open access: yesSymbolic Interaction, EarlyView.
Boundary‐work describes the activities of social groups as they seek to differentiate themselves from others to establish credibility, authority, or to protect their interests. While a growing body of literature explores occupational boundary‐work in health care, limited research has focused on how lay actors practice boundary‐work online.

The EU and Syria – Time to Play behind Closed Doors. Jean Monnet/Robert Schuman Paper Series Special Issue, September 13, 2013 [PDF]

open access: yes, 2013
From the Introduction. Since the – presumed – utilization of chemical weapons against civilians by the Assad regime late August, the members of the Euro-Atlantic community have been building the case for a military intervention, a punishing mission ...

Carrying a Big Carrot: Linking Multilateral Disarmament and Development Assistance [PDF]

open access: yes, 1991
This article proposes, as a new element of the liberal internationalism that should characterize the post-Cold War world, a simultaneous solution to these three problems.

Staging concept for aging management: Definition, mechanism, and coping strategies

open access: yesVIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...
