we prove that the class of profinite groups $g$ that have a factorization $g=ab$‎ ‎with $a$ and $b$ abelian closed subgroups‎, ‎is closed under taking inverse limits‎ ‎of surjective inverse systems‎. ‎this is a generalization of a recent result by k. h. hofmann and f. g. russo‎. ‎as an application we reprove their generalization of iwasawa's structure theorem for‎ ‎quasihamiltonian pro-$p$...

in this paper‎, ‎we determine the simple groups $g=ab$‎, ‎where $b$ is isomorphic to $l_{3}(4)$ and $a$ isomorphic to an alternating or a symmetric group on $ngeq5$‎, ‎letters‎.

Decarbonization of the shipping sector is inevitable and can be made by transitioning into low- or zero-carbon marine fuels. This paper reviews 22 potential pathways, including conventional Heavy Fuel Oil (HFO) fuel as a reference case, “blue” alternative produced from natural gas, “green” fuels biomass solar energy. Carbon capture technology (CCS) installed for fossil (HFO liquefied gas (LNG))...

This research was conducted to measure Persian EFL students’s degree of willingness to write in English. To reach the goal, semi-structured interviews were conducted, deriving inspiration from earlier works of McCrosky and Baer (1985), MacIntyre, Dornyei, Clement, and Noels (1998), and Yashima (2002) on willingness to communicate. The participants of the study were 29 individuals comprising 23 ...
