Technologies and New Methods for Determining the Burning Rate of Solid Propellants [PDF]
The burning rate plays animportant role in determining the performanceandballistic behavior of solid rocket propellant. In this paper, the effect of various factorson burning rate, such as combustion chamber pressure, poropellant grain initial ...

Abstract This study investigates how small and medium‐sized enterprises (SMEs) respond to deglobalization and economic nationalism, using historical evidence from fascist Italy, a period of autarky and restricted international trade. While prior research has focused primarily on larger firms, especially multinational enterprises (MNEs), the strategic ...

A Microkrystite from the Australasian Tektite/Microtektite Strewn Field
Abstract Microkrystites are glassy impact spherules. They contain primary crystallites carrying information on the physical and chemical conditions prevailing during vaporization, melting, and ejection in large impact cratering events. We report on the geochemistry and mineralogy down to nanometer scale of the first microkrystite (ODP1144A,14) from the

Noisy Politics, Quiet Technocrats: Strategic Silence by Central Banks
ABSTRACT In contrast to the “quiet” politics of the pre‐2008 period, macroeconomic policy has become “noisy”. This break raises a question: How do independent agencies designed for quiet politics react when a contentious public turns the volume up on them?

ABSTRACT Can sociologists feel? Sociological writing can be beautiful, making us think differently about people, processes, and structures. Yet traditional academic writing that does this is rare. For example, most articles adhere to a jargon‐filled format and structure that mimics a detached and disciplined writer.

Optimization design of anti-creep reinforcement structure for solid rocket motor propellant grain
To address the creep issue that arises during the long-term vertical storage of solid rocket motor (SRM), a method was proposed that involved embedding a specially shaped functional combustible core model (reinforcement structure)into the propellant ...

Tracing the Untraceable: A Review and Discussion on the Forensic Attribution of 3D‐Printed Firearms
3D‐printed firearms are rapidly evolving and challenge traditional forensic identification. This review highlights emerging attribution methods, from deposition striae and base‐plate marks to polymer and GSR residual traces, firing marks, and quantitative imaging, identifying the research needed to support robust forensic attribution interpretation and
