Strategic Reconfiguration of Agriculture Sustainability in APEC Countries: Trade Exposure, Technological Transition, and Climate Constraints

Land Degradation &Development, EarlyView.
ABSTRACT In developing economies, the agricultural sector enhances national food security, employment, and economic prosperity, while it is also closely linked to the ecological system. International trade, technological innovations, and fertilizer use are modern inputs to increase output; however, their unsustainable use leads to environmental ...

GRBs, fireballs and precessing Gamma Jets [PDF]

, 2001
Fireballs are huge isotropic explosions models widely believed to explain Gamma Ray Burst, GRBs (Piran,1999); ever-new versions consider wide beamed (10degrees) Jet explosions hitting external shells.

Assessing Land Use Conflict in the Yangtze River Middle Reaches Megalopolis for 2030: Integrating Landscape Pattern Analysis and Scenario Simulation to Address Uncontrolled and Severe Conflict Zones

Land Degradation &Development, EarlyView.
ABSTRACT Land use conflicts (LUCs) significantly impact regional food security and ecological security. Identifying LUCs helps cut down ecological risks. This study focuses on the Yangtze River Middle Reaches Megalopolis (YRMRM) as a case, employing a landscape pattern approach to construct a land use conflict measurement model.

Design and Development of a Modular Ballistic Pendulum for High‐Impulse Measurement in Contact and Near‐Field Explosive Loading

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Measuring impulse from explosive charges in contact and near‐field configurations presents practical challenges due to wide variation in impulse magnitude. Ballistic pendula are widely used for impulse measurement, but many existing designs are limited to narrow operating envelopes or are poorly suited to repeated contact testing and tamped ...
