Incorporation of TiC particles on AlSi 4340 low alloy steel surfaces via tungsten inert gas melting [PDF]

open access: yes, 2011
Surface cladding utilizes a high energy input to deposit a layer on substrate surfaces providing protection against wear and corrosion. In this work, TiC particulates were incorporated by melting single tracks in powder preplaced onto AISI 4340 low alloy

The effect of helicopter configuration on the fluid dynamics of brownout [PDF]

open access: yes, 2008
Brown’s Vorticity Transport Model, coupled to an additional particle transport model, is used to simulate the development of the dust cloud that can form around a helicopter when operating in dusty or desert conditions.

Off-axis MgB2 films using an in situ annealing pulsed laser deposition method [PDF]

open access: yes, 2005
Highly smooth and c-axis oriented superconducting MgB2 thin films were prepared by pulsed laser deposition (PLD) with off-axis geometry. The films were deposited on Al2O3-C substrates perpendicularly aligned to a stoichiometric MgB2 target in a 120 mTorr

Rapid solidification of metallic particulates [PDF]

open access: yes
In order to maximize the heat transfer coefficient the most important variable in rapid solidification is the powder particle size. The finer the particle size, the higher the solidification rate.

Epoxy-based composites with size-fractionated waste Areca sheath: an experimental investigation on the macroscopic and vibrational properties

open access: yesFracture and Structural Integrity
The use of Areca sheath in developing a newer composite material is proposed in this article. The Areca sheath particulates are extracted by pulverizing long sheaths into different sizes of particulates and are reinforced into the epoxy to process the ...

Nutrients and Acid in the Rain and Dry Fallout at Fayetteville, Arkansas (1980-1982) [PDF]

open access: yes, 1983
Wet and dry fallout at Fayetteville, Arkansas have been collected separately and analyzed since April, 1980. The precipitation-weighted-average pH for two yearly periods of rainfall were 4.72 (6/80-5/81) and 4.75 (6/81-5/82).
