Artificial weathering aging of PPT coatings made from recycled PET to protect concrete: Nanomechanical properties evaluation by Adrián Bórquez-Mendivil, Jorge Luis Almaral-Sánchez, Jesus Eduardo Leal-Perez, César Modesto-Acosta, Joaquin Flores-Valenzuela, Orlando Auciello, Blanca Alicia García-Grajeda, José Miguel Mendivil-Escalante, Sergio G. Flores-Gallardo, Roberto P. Talamantes-Soto, Abel Hurtado-Macías

“…The analysis of the molecular degradation of the PPT coatings was performed by Fourier transform infrared spectroscopy (FT-IR), which revealed that the rupture of C–H bonds caused the nanomechanical properties of the coatings to decrease; Hi = 200 ± 5 MPa to Hi = 32 ± 18 MPa, Hs = 125 ± 12 MPa to Hs = 12 ± 5 MPa and E = 5.1 ± 1.01 GPa to E = 1.05 ± 0.23 GPa.…”

Costimulation of Murine Osteoblasts with Interferon-γ and Tumor Necrosis Factor-α Induces Apoptosis through Downregulation of Bcl-2 and Release of Cytochrome c from Mitochondria by Mayumi Iguchi, Miki Hiroi, Haruhide Kanegae, Yoshihiro Ohmori

“…To elucidate the underlying molecular mechanisms, we investigated the effect of IFNγ and TNFα on the proliferation and survival of clonal MC3T3-E1 mouse osteoblasts. We found that although IFNγ or TNFα alone affected cell growth and survival only marginally, costimulation with both synergistically inhibited cell growth and reduced cell viability. …”

Electrochemical Impedance Spectroscopy-Based Characterization and Modeling of Lithium-Ion Batteries Based on Frequency Selection by Yuechan Xiao, Xinrong Huang, Jinhao Meng, Yipu Zhang, Vaclav Knap, Daniel-Ioan Stroe

“…This paper establishes a mathematical expression for a temperature–SOC-based impedance model at specific frequencies, i.e., 1 Hz, 20 Hz, and 3100 Hz. When comparing the models at these three frequencies, it was found that the model fitting accuracy is highest at 20 Hz, making it applicable across a wide range of temperatures and SOCs. …”

Elimination Kinetics of Ethanol in a 5-Week-Old Infant and a Literature Review of Infant Ethanol Pharmacokinetics by Jonathan B. Ford, Mac T. Wayment, Timothy E. Albertson, Kelly P. Owen, Joshua B. Radke, Mark E. Sutter

“…Primary ethanol metabolism occurs through alcohol dehydrogenase, but minor metabolic pathways such as the P450 enzymes CYP2E1 and CYP1A2 and the enzyme catalase exist. These enzymes have distinct developmental stages. …”

Effect of dynamic coupling in an inferior olive neuron model and synchronization by M. R. Tchuisseuh, P. Guemkam Ghomsi, A. C. Chamgoué, F. M. Moukam Kakmeni

“…Assuming two coupled neurons with parameter mismatch, it is observed that an increase in the external coupling strength ɛ1 favors their synchronization. Furthermore, the analog circuit of the complete new model confirms the burst analysis and the existence of chaos in the model.…”

Comment on “Carbon in Trees in Tasmanian State Forest” by Christopher Dean

“…Also, using their data, earlier work on long-term fluxes accompanying conversion of wet-eucalypt forests to harvesting cycles was found to correspond to 0.56(±0.01) Mha (i.e., >1/3 of State forest), 76(±2)% of which is in the commercial production area—in contrast to their claim that earlier work referred to a small and atypical proportion.…”
