In this paper, HSC software is used to estimate the effects of composition and processing conditions on reduction behavior iron oxide pellets, i.e., hematite (Fe2O3), magnetite (Fe3O4), wustite (FeO), pure (Fe), carbide (Fe3C), in a wide temperature range from room (RT) 1000°C presence H2 CO mixtures. The reducibility ores, particular Fe2O3, Fe3O4, FeO, Fe discussed. choice reducing agents explained, with proving be more effective agent at high temperatures thermodynamic point view. However,...
In this letter, we suggest a local covariant action for gauge field theory of fermionic Continuous-Spin Particles (CSPs). The is invariant under transformations without any constraint on both the and transformation parameter. Fang-Fronsdal equations tower massless fields with all half-integer spins arise as particular limit equation motion CSPs.
In this paper, we first propose the bosonic (fermionic) modified Wigner equations for continuous spin particle (CSP). Secondly, starting from (Fang-)Fronsdal-like equation, will reach to action of gauge field in flat spacetime, presented recently by Metsaev (A)dS spacetime. We shall also explain how obtain proposed gauge-fixed motion. Finally, consider massive higher-spin and, taking infinite limit, arrive at CSP action.
The exploration of scalar field theories that exhibit Carroll and Galilei symmetries has attracted a lot attention. In this paper, we generalize these studies to fermionic construct consistent electric magnetic descriptions Carrollian Galilean spin $\frac{1}{2}$ fermions. We showcase various methods offer complementary perspectives into the limiting process underlying relativistic theories. Moreover, extend our study $\mathcal{N}=1$ off-shell supersymmetric in four dimensions. By introducing...
A bstract Action principles for the single and double valued continuous-spin representations of Poincaré group have been recently proposed in a Segal-like formulation. We address three related issues: first, we explain how to obtain these actions directly from Fronsdal-like Fang-Fronsdal-like equations by solving traceless constraints Fourier space. Second, introduce current, similar one Berends, Burgers Van Dam, which is bilinear pair scalar matter fields, bosonic field can couple...

Building on Segal's local free action principle for bosonic unconstrained higher spin gauge fields in $d$-dimensional $(\mathrm{A})\mathrm{d}{\mathrm{S}}_{d}$ spacetime, we present a similar \`a la Segal fermions spacetime. Moreover, at the level of equations motion, demonstrate how Fronsdal and Fang-Fronsdal spacetime are related, respectively, to Euler-Lagrange fermionic actions mentioned above.
A bstract We construct, for the first time, an off-shell supersymmetric continuous spin gauge theory in 4-dimensional Minkowski spacetime, both constrained and unconstrained Lagrangian formulations. As extension to on-shell description [1], we employ auxiliary field close algebra of supersymmetry transformations off-shell. The 4d $$ \mathcal{N} <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>N</mml:mi> </mml:math> = 1 massless supermultiplet is then denoted by (Φ , H; Ψ),...
Abstract In the current study, biocorrosion resistance and mechanical properties of Ti–XAl–2Fe–3Cu (wt%) ( X = 6, 4, 2 wt%) alloy produced by powder compact extrusion blended elemental powders were optimized using response surface methodology in order to gain best combination processing parameters. To run optimization process, central composite design with three equal levels oxygen, hydrogen aluminum was used and, employing ANOVA, analysis variance implemented. The results showed that...

However, question remains: what that corresponds symmetry? In this paper, we derive novel equation, called Carroll-Schr\"odinger which describes dynamics Carrollian framework. We also introduce algebra, conformal extension of centrally extended show it algebra dimensions. generalize our results arbitrary dimensions...
