ABSTRACT Fertilizers play a crucial role in feeding the world's population and achieving food security, yet recent disruptions in the global fertilizer market have affected pricing, usage, response, and efficiency of mineral fertilizers. We employed the Quantile Regression (QR) model to investigate the determinants of wheat and maize production across ...

Exploring the Interior Structure of (16) Psyche Through Basin‐Scale Collisions
Abstract Asteroid (16) Psyche, the largest member of the M/X‐type asteroids, may be the leftover core of a differentiated planetesimal. As such (16) Psyche will be explored in detail by NASA's discovery‐class Psyche mission in 2029. This will be the first mission to orbit a metal‐rich asteroid, or any asteroid in the 100–500 km size range.

Cryogenic Liquid Rocket Engine Test Bench Fault-Tolerant Control System: Cooling System Application
Abstract A nonlinear fault-tolerant control strategy relying on quantitative physics-based models for a cryogenic combustion bench operation is proposed in this paper. The aim is to improve the reliability of a cryogenic bench operation in the transients and to allow to converge to a wider range of operating points.

Compelling private sport speech
Abstract The intermingling of sport and political speech has become increasingly poignant. Although basketball star Michael Jordan has now clarified that his famous statement that “Republicans buy sneakers, too” was made in jest when asked about why he did not make political statements, Michael Jordan was well within his rights to avoid the political ...

The McKinleys of Punch: Politics and the Press in Melbourne, 1870s to 1920s
This article re‐examines the Melbourne Punch (1855–1925; known simply as Punch from 1900) as a political weapon in the cut‐and‐thrust of Victorian, local, and national politics, in the hands of its longest‐serving, but least‐known proprietor, Alexander McKinley (1848–1927).

The article presents the structure and the main characteristics of systems of a multi-purpose thermal high-precision testing bench for firing tests of non-hypergolic low-thrust rocket engines (LTRE). The vacuum system provides the initial vacuum in the chamber; the fuel system makes it possible to conduct research and tests of LTRE with the thrust 5 ...
