Tillage Manure Managemen and Water Quality, April 2005 [PDF]

open access: yes, 2005
Tillage and manure application practices significantly impact surface and ground water quality in Iowa and other Midwestern states. Tillage and manure application that incorporates residue and disturbs soil result in higher levels of soil erosion and

The energetics of water on oxide surfaces by quantum Monte Carlo

open access: yes, 2006
Density functional theory (DFT) is widely used in surface science, but gives poor accuracy for oxide surface processes, while high-level quantum chemistry methods are hard to apply without losing basis-set quality.

Milling Parameters Optimization for Surface Quality [PDF]

open access: yes, 2016
The Taguchi method is a powerful tool to experiment design optimization and is used in this work to optimize the cutting parameters, which reduce the chatter effect on surface quality. The present study includes feed per tooth, cutting speed, radial and axial depth of cut as control factors.

Friction characteristics of graphite and graphite-metal combinations at various temperatures [PDF]

open access: yes, 1970
Characteristics of the coefficient of friction of graphite and of graphitic combinations between 70 and 4000 degrees F are given. Graphite's good frictional quality is attributed to a gas film on surface platelets. Major factors investigated are, surface

A novel drifter designed for use with a mounted Acoustic Doppler Current Profiler in shallow environments [PDF]

open access: yes, 2013
We present a novel design for a surface drifter, mounted with a pulse-coherent Acoustic Doppler Current Profiler (ADCP) for measuring near-surface (depths 0.18-1 m) flows.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
