The Mechanisms of Catalysis by Metallo 𝛽-Lactamases by Michael I. Page, Adriana Badarau

“…The metal-ion also lowers the pKa of the directly co-ordinated water molecule so that the metal-bound hydroxide ion is a better nucleophile than water and is used to attack the 𝛽-lactam carbonyl carbon. An intrinsic property of binuclear metallo hydrolytic enzymes that depend on a metal-bound water both as the attacking nucleophile and as a ligand for the second metal-ion is that this water molecule, which is consumed during hydrolysis of the substrate, has to be replaced to maintain the catalytic cycle. …”

Topological Indices of Derived Networks of Benzene Ring Embedded in P-Type Surface on 2 D by Feng Yin, Muhammad Numan, Saad Ihsan Butt, Adnan Aslam, Andleeb Kausar

“…This structure is the simplest possible tilling of the periodic minimal surface P which contains one type of carbon atom. In this paper, we compute general Randić, general Zagreb, general sum-connectivity, first Zagreb, second Zagreb, and ABC and GA indices of two operations (simple medial and stellation) of 2 D network of benzene ring. …”

Future yield growth in Africa mitigates agricultural greenhouse gas emissions by Saloni Shah, Dan Blaustein-Rejto, Linus Blomqvist

“…If Africa more than doubled yields from 2025 levels to meet future food demand while avoiding cropland expansion, an estimated 2.0 gigatons of carbon-dioxide equivalent per year in emissions could be avoided, equivalent to nearly 81% of all Africa’s emissions from agriculture, forestry, and land use in 2021.…”

Estimation of Air Pollutant Emissions from Heavy Industry Sector in North Korea by Young Won Lee, Yong Pyo Kim, Min Ju Yeo

“…The heavy industry sector in North Korea was classified according to the South Korean definition, and the air pollutant emissions that it generated were estimated for 2017. Emissions of carbon monoxide (CO), nitrogen oxides (NOx), and sulfur oxides (SOx) by the heavy industry sector in North Korea were 22, 73, and 31%, respectively, of those in South Korea’ air pollutant emissions. …”

The key metabolic genes and networks regulating the fruit acidity and flavonoid of Prunus mume revealed via transcriptomic and metabolomic analyses by Xuan Gao, Shuangshuang Wu, Guosheng Lv, Mengyang Wang, Lingxiang Li, Yahui Liu, Feng He, Jiaxin Xiao

“…While the differentially accumulated metabolites were mainly associated with flavone and flavonol biosynthesis and amino acid and carbon metabolism. Moreover, we identified key metabolites, such as citric and succinic acids, which may be central to the development of acidity in Mei fruit, and determined that they are under the regulatory influence of specific genes, including galactinol-sucrose-galactosyltransferase 5, mitogen-activated protein kinase kinase kinase NPK1-like, glutamate receptor, and chalcone isomerase. …”

Utopías y nacionalismo cultural en América Latina. La interpretación de Andrés Sabella a la contribución de Mariátegui, Vallejo y Eguren by José Antonio González Pizarro

“…Se hace una relectura de los autores peruanos José Carlos Mariátegui, César Vallejo y José María Eguren, desde la visión del poeta y ensayista chileno Andrés Sabella, poniendo el énfasis en la noción de utopía —como lo no lugar, lo imposible— no solamente en el ámbito político-económico sino desde la construcción de un “mundo” donde la imaginación, la ensoñación, pueda edificar en la niñez, una visión contra la fealdad, lo monocromático, estableciendo con fuertes imágenes líricas el “mundo imposible” de lo que se estimaba lo “perdido” en la infancia. …”
