steel research international, EarlyView.The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...

Flight Path Angle Steering with Lambert Guidance Reference [PDF]
فصلنامه علوم و فناوری فضایی, 2010 In this paper a new guidance technique for ballistic missiles and launch vehicles is proposed. Generally the Lambert guidance is used to generate missile nominal (correlated) parameters through powered flight to put it in a ballistic flight path. Because

How many shots are enough? Optimizing precision measurements when testing lead‐free ammunition
Wildlife Biology, EarlyView.Growing concern about lead exposure in scavenging wildlife and the consumers of game meat has increased interest in evaluating the performance of lead‐free rifle ammunition. Testing both accuracy and precision helps ensure reliable shot placement while reducing the risk of non‐fatal woundings.

Global Policy, EarlyView.ABSTRACT An inherent divide features within the Lisbon Treaty between civilian and military/security competences; something previously more obvious via the ‘pillar system's’ separations. This division follows the Member States (MS) (natural) protection of their military/defence autonomy; their core sovereign powers.

The Unintended Consequences of German Deterrence
Global Policy, EarlyView.ABSTRACT Germany's evolving deterrence posture boils down to continued participation in NATO nuclear sharing and an ambitious conventional rearmament program. Due to its non‐nuclear status and a result of decades of underinvestment, Germany prioritizes modern conventional weapons.
