Using Thermal Analysis Studying Reaction Process of Forsterite with Iron Ore Tailings
, 2011 In this paper, the iron ore tailings that the metallurgy castoff can be recycled were adopted to synthesize forsterite refractory materials, thermal analysis was used to analyze the reaction process of the forsterite.

, 1988 Computer modeling of the Beijing low temperature, basement aquifer system has shown that secular natural convection of meteoric waters down to depths greater than 5 km can produce a temperature field which is similar to that observed in deep wells ...

Zur Physik des Kugelhaufen Hochtemperaturreaktors bei massiven Wassereinbruchstörfällen
, 1989 A pointkinetics model was developed to describe qualitatively hypothetical water ingress transients in the primary loop of High Temperature Reactors. Neutron kinetics, heatflow balance and the chemical reaction of graphite corrosion together with their ...

Geomagnetic reversal rates following Palaeozoic superchrons have a fast restart mechanism
, 2016 Long intervals of single geomagnetic polarity (superchrons) reflect geodynamo processes, driven by core–mantle boundary interactions; however, it is not clear what initiates the start and end of superchrons, other than superchrons probably reflect lower ...

# Collatz Final Gate v4.4a — Main Proof Only ## OverviewThis preprint develops a **gate-based, audit-friendly proof program** for the Collatz conjecture by separating: - **Unconditional (annealed / kernel-level) results**: spectral gap and absorption/escape estimates for a reversible “entropic Laplacian” model on the Collatz 2-adic space ...

# Overview This record presents version **v3.8a** of an analytic–thermodynamic program for the Collatz dynamics on the 2-adic space \(M_C \simeq \mathbb{Z}_2\). We study the **reversible, self-adjoint** annealed kernel \(K\) and the **entropic Laplacian** \(\Delta_C^{(\infty)} := I - K\), together with a unitary dilation \(K = J^\dagger U_T J\) that ...
