Abstract:
The existing mathematical models of anaerobic treatment processes were mainly developed for ideally mixed reactors with no concentration gradients on substrates, intermediates, products and bacteria inside the reactor. But for conventional UASB reactors with low upward velocity, the distribution of these components along the reactor height is very far from uniform. This paper presents an integrated mathematical model of the functioning of UASB reactor taking into account this non-uniformity as well as multiple-reaction stoichiometry and kinetics. In general, our integrated model includes the f

Abstract The High Temperature Test Reactor is a 30-MWth helium-cooled, graphite-moderated, prismatic-type gas reactor developed by the Japan Atomic Energy Agency (JAEA).

In this paper, the coarse mesh transport method is extended to hexagonal geometry. This stochastic-deterministic hybrid transport method calculates the eigenvalue and explicit pin fission density profile of hexagonal reactor cores. It models the exact detail within complex heterogeneous cores without homogenizing regions or materials, and neither block-level nor core-level asymmetry poses any limitations to the method. It solves eigenvalue problems by first splitting the core into a set of coarse meshes, and then using Monte Carlo methods to create a library of response expansion coefficien

Abstract:
On the way to a new era of our society which will be based on hydrogen energy, it is needed to develop on-site hydrogen production systems to cover current insufficient infrastructures of hydrogen supply network systems. For this, a highly efficient compact reformer can be one of the most suitable solutions for on-site production of hydrogen which is supplied to distributed electric power-generation systems. But, the local and overall energy balance in the reformer should be precisely controlled since the reforming reaction processes of hydrocarbon fuels are very sensitive to reaction temperat

Abstract:
A compact tubular-type fuel reformer was fabricated and operated under fuel-rich combustion conditions of methanol, focusing on the partial oxidation reaction (POR). Ceramic honeycomb strainer blocks were inserted in the reactor. In the authors’ previous study, Case-1 of only one honeycomb block insertion showed that the reaction region formed in the downstream of the block. This block worked as a reaction stabilizer. The other condition, Case-2, was operated with the secondary honeycomb block inserted in the downstream of the reaction region in addition to the first block. This geometrical st

Abstract:
Blockchain-based systems are run by a decentralized network of participants and are designed to be censorship-resistant. We use sanctions imposed by the U.S. Department of Treasury on Tornado Cash (TC), a smart contract protocol, to study the impact and effectiveness of regulation in decentralized systems. We document an immediate and lasting impact on TC following the sanction announcement, measured by market reaction, transaction volume, and diversity of users. Still, net flows into TC contracts recover to and surpass pre-announcement levels for most pools, supporting viability of TC. Eviden

Abstract:
Tire rubber waste (TRW) is a complex mixture of materials, such as rubbers, steel, textile fibers, carbon black, and other additives. Its polluting capacity is a severe environmental problem, especially in landfills and waste management processes. As a practical solution to mitigate TRW’s environmental impact, thermoplastic elastomers (TPE) commonly reuse the ground tire rubber (GTR). This work presents an in-situ devulcanization of ground tire rubber (DGTR) and re-vulcanization of devulcanized ground tire rubber using dicumyl peroxide (DCP) and waste ethylene-vinyl-acetate (wEVA).

Abstract:
Beside carbon black, silica powder is the other important filler used to reinforce various colored rubber products. In order to improve the compatibility between silica particles and rubber phase, this work has focused on preparing an NR composite, reinforced by silica generated inside the NR matrix or ‘in situ’. The silica particle was formed by a sol-gel process of tetraethoxysilane (TEOS) dispersed in NR latex. The latex used was concentrated latex having 60% rubber content, and already contained water and ammonia, two ingredients needed for the sol-gel reaction. The conversion of TEOS to s
