Effect of strain rate on specific fracture energy and micro-fracture surface properties of rock specimen under dynamic uniaxial compression [PDF]

, 2023
Effects of strain rate on specific fracture energy and micro-fracture surface properties of rock specimen were investigated at strain rates of ∼ 60–115.0 s-1. To achieve this, rock breakage was conducted under dynamic uniaxial compression using the split

Dry Grinding Kinetics of Gölbaşı (Ankara) Andesite in Ball Mill. [PDF]

International Journal of Economic and Environment Geology, 2017
Kinetic study using a laboratory steel ball mill was carried out to determine dry grinding properties of andesite sample. The Si (specific rate of breakage) values were determined by using the single sized feed fractions of - 850+600 µm, -600+425 µm ...

Investigating the conformational stability of prion strains through a kinetic replication model. [PDF]

PLoS Computational Biology, 2009
Prion proteins are known to misfold into a range of different aggregated forms, showing different phenotypic and pathological states. Understanding strain specificities is an important problem in the field of prion disease.

Optimization of the Fabrication of Cold Drawn Steel Wire Through Classification and Clustering Machine Learning Algorithms

IEEE Access, 2019
The demanding deformations steel is subjected to during drawing may result in the breakage of the wire. The hypothesis of this research is that drawing failure is not a random event but can be predicted using a suitable approach.

Constructing hierarchical porous structure in microsized silicon/carbon nanotubes composite anode with LiF-rich solid-electrolyte interfaces for highly stable lithium-ion batteries

JPhys Materials, 2022
Lithium-ion batteries (LIBs) with silicon microparticle anodes provide a high capacity, low cost, low environmental impact, and ease of production. However, the rapid capacity degradation and low Coulombic efficiency (CE) are impediments to their further

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Clerocidin interacts with the cleavage complex of Streptococcus pneumoniae topoisomerase IV to induce selective irreversible DNA damage [PDF]

, 2006
Clerocidin (CL), a diterpenoid natural product, alkylates DNA through its epoxide moiety and exhibits both anticancer and antibacterial activities. We have examined CLaction in the presence of topoisomerase IV from Streptococcus pneumoniae.
