Introduction Currently, there is tremendous interest in the field of micro-structured gas-liquid contactors containing modified catalytic coatings on its micro-structured internals (Fig. 1) [1]. The most recent trend in the design of three-phase catalytic microreactors focuses on the use of structured catalyst supports, i.e. that the catalyst has to be deposited on a rigid, orderly arranged sup...

In this paper, we prove the existence and uniqueness of fixed points for cyclic (α,β)-admissible type F-contraction and F−weak contraction under the setting of modular spaces, where the modular is convex and satisfying the ∆2-condition. Later, we prove some periodic point results for self-mappings on a modular space. We also give some examples to s...

Raschig Super-Pak is a novel development in structured packing product technology that is fundamentally different to the well known corrugated perforated or nonperforated, textured sheet metal structured packings. It comprises of a systematic sequence of smooth sinusoidal waves above and below the plain of the metal sheet. Total reflux distillation tests with Raschig Super-Pak 300 were conducte...

INTRODUCTION Structured packings of the corrugated sheet type have become increasingly popular for the application in distillation and absorption columns, due to their very good performance characteristics. Commonly, at suband near-atmospheric pressures, structured packings outperform random packings and trays in capacity and/or separation efficiency (see, e.g., Kurtz et al., 1991; Brunazzi, E....

We construct integer error-correcting codes and covering for the limited-magnitude error channel with more than one error. The are lattices that pack or cover space appropriate ball. Some of constructions attain an asymptotic packing/covering density is constant. results obtained via various methods, including use in Hamming metric, modular B <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" ...
