New pneumococcal serotype 20C is a WciG O-acetyltransferase deficient variant of canonical serotype 20B by Jigui Yu, Neil Ravenscroft, Peter Davey, Roshan Liyanage, Oliver Lorenz, Michelle M. Kuttel, Stephanie W. Lo, Feroze A. Ganaie, Moon H. Nahm

“…Herein, we characterize a newly discovered capsule type, 20C, that differs from serotype 20B via the inactivation of capsule O-acetyltransferase gene, wciG. Structural analysis demonstrated that 20C and 20B share an identical repeat unit [→3)-α-D-GlcpNAc-[β-D-Galf-(1→4)][α-D-Glcp-(1→6)]-(1→P→6)-α-D-Glcp-(1→6)- β-D-Glcp-(1→3)-β-D-Galf 5,6Ac2-(1→3)-β-D-Glcp-(1→], except for the absence of WciG-mediated O-acetyl group at terminal galactofuranose (β-D-Galf). …”

The Chinese State, Incomplete Proletarianization and Structures of Inequality in Two Epochs by Wu Jieh-min, Mark Selden

“…We particularly emphasize the widening income and opportunity gap separating the mass of laborers from the nouveau riche and seek to provide a structural analysis of the roots of this phenomenon. To be sure, many other nations have experienced rising social inequality in this epoch of neo-liberalism, notably the United States and Japan, but Chinese inequality has assumed distinctive forms consonant with its class structure, population control arrangements, and differential welfare policies and citizen rights. …”

Estimation and evaluation of iron reserves in the eastern area of Eileh1 mine, Razavi Khorasan province by Hamid Esmati Daroneh, Maryam Gholamzadeh

“…Classical reserve estimation methods rely on traditional statistics and geometric calculations, while geostatistical methods, such as those based on regional variables, are grounded in spatial structure analysis and utilize the Kriging method. Among classical estimation techniques, the inverse distance weighting (IDW) method is recognized for its accuracy. …”
