THERMIONIC EMISSION PROPERTIES OF OXIDIZED HAFNIUM, ZIRCONIUM, TITANIUM, AND NIOBIUM IN A BARIUM ATOM FLUX
This paper investigates the thermionic emission and adsorption properties of oxidized transition metals (Hf, Zr, Ti, and Nb) exposed to a flux of barium atoms. The surface cleanliness and oxidation kinetics were monitored using Auger electron spectroscopy under ultra-high vacuum conditions. The...

INVESTIGATION OF PLASMA CHARACTERISTICS PRODUCED ON A BINARY SODIUM CHLORIDE SURFACE
The present study examines the plasma produced when a solid NaCl sample is exposed to pulsed Nd:YAG laser radiation. Measurements were performed at a vacuum pressure of 10⁻² Torr with a 1064 nmlaser pulselasting20ns. Emission spectral were used to evaluate two principal plasma quantities: electron...

NONTHERMAL PLASMA APPLICATION TO HYDROGEN PRODUCTION
Nonthermal plasma (NTP) is being investigated as an electrically driven route for hydrogen production because energetic electrons can activate methane, water vapour and carbon dioxide without requiring the entire gas phase to reach thermochemical equilibrium. This article compares dielectric...

INVESTIGATION OF SCATTERING Ne+ AND Ar+ IONS FROM BLACK PHOSPHORINE AT THE GLANCING INCIDENCE
In this paper, the scattering process of Ne+ and Ar+ ions bombarding the surface of black phosphorene at grazing (small) angles is computer-simulated using the binary collision approximation method. The characteristic trajectories and energy spectra of the Ne+ and Ar+ ions scattered from this...

ANALYSIS OF FLUID TEMPERATURE CHANGES DURING DISCHARGE IN HEAT ACCUMULATORS AND VALIDATION OF THE MATHEMATICAL MODEL
Among heat accumulators, hot water storage tanks are the most widely used due to their low cost, simplicity, and ease of operation, as well as their low environmental impact. The temperature distribution within a hot water storage tank is a key factor governing the thermal behavior and hot water...

EFFECT OF MINERAL FERTILIZER RATES ON THE GROWTH, GRAIN YIELD, AND ECONOMIC EFFICIENCY OF SORGHUM
This study evaluated the effects of mineral fertilizer rates on the leaf area index, grain yield, and economic efficiency of the “Daulet” sorghum cultivar. The highest leaf area index of 5.21 m²/m² was recorded with N240P140K120 kg/ha. However, the highest grain yield of 6.12 t/ha, net profit of 18...

THE PHILOSOPHY OF INTELLECTUALISM: A PHILOSOPHICAL INTERPRETATION OF REASON, KNOWLEDGE AND HUMAN PERFECTION
The article interprets intellectualism as a philosophical position that gives reason and knowledge the leading place in the human comprehension of being, and traces its formation, its conceptual structure and its present-day meaning. The problem is posed in a situation where cognition suffers from...
