Significant attention to the presence of corrosion control during both the design and operational phases, including efforts in corrosion monitoring. Domestic waste has shown potential as an ecological corrosion inhibitor for carbon steel when exposed to 1 M Hydrochloric acid solution. Various concentrations of the waste were tested on carbon steel in an acidic environment through weight loss measurements over 7, 14, and 21 days. The results indicated that higher concentrations enhanced the corrosion resistance of the steel, with a maximum inhibition efficiency of 98.28%. In conclusion, domestic waste is an effective natural corrosion inhibitor that helps protect the steel surface and minimizes corrosion in carbon steel.

Mazkur tadqiqot etilendan asetat olish jarayonlarining kinetika va texnologik jihatlarni oʻrganishga bagʻishlangan. Ushbu ishda etilendan vinilasetatning katalitik sintezi va ushbu jarayon optimallashtirish texnologiyasi yoritilgan. Vinilasetat kimyo sanoatida polimerlar, qoplama materiallari, elimlar va boshqa mahsulotlarni ishlab chiqarishda asosiy xomashyo hisoblanadi. Uning etilendan sintezi hozirgi zamonaviy texnologiyalar va samarali katalizatorlarni qoʻllash bilan yuqori hosildorlikka erishishga imkon beradi. Katalizatorning samaradorligini saqlash uchun regenetorlarda qayta tiklash amalga oshiriladi. Bu ekologik xavfsizlikni taʼminlash va ishlab chiqarish tannarxi kamaytiradi. Etilendan vinilasetatning katalitik sintezi va texnologiyasi yuqori samaradorligi va ekologik tozaligi bilan zamonaviy kimyo sanoati uchun strategik ahamiyatga ega.

The Poética de Os Sertões (Poetics of Rebellion in the Backlands, 2010), featuring essays by Haroldo and Augusto de Campos, uncovers complex “poetic layers” within the prose of Euclides da Cunha. For the poet and translator Augusto de Campos, there are metrical verses in Os Sertões (Rebellion in the Backlands), “subterranean poems” within the prose — which I interpret here as “hidden diagrams.” The distinctive “tone” of Euclides’ text, characterized by its “rhythmic density, plasticity, and sound,” results from an operation that can be described as typically diagrammatic (sensu Charles S. Peirce). My analysis suggests that Euclides employs a form of “iconic calculation,” where the interplay of interrelated prosodic, phonetic, and syntactic structures generates a distinctive tension between the temporal act of reading and the spatial organization of the text. I aim to offer a framework with implications that can be generalized to various instances of diagrammatic reasoning in literature. In my argument, the “physicality of the Euclidean sign,” or the “pregnant areas of poetry” in his prose, has a diagrammatic nature.
