Plasma-Assisted Combustion (PAC) has shown potential in improving the ignition, extinction, and dynamic performance of combustion systems. In this work, nanosecond repetitively pulsed (NRP) spark discharges are applied to extend lean blow out (LBO) limit SICCA-Spray burner. This laboratory-scale atmospheric test rig is equipped with a swirl spray injector representing an idealized fashion singl...

Production and transport of reactive species through plasma–liquid interactions play a significant role in multiple applications biomedicine, environment, agriculture. Experimental investigations the mechanisms typical air plasma species: hydrogen peroxide (H2O2) ozone (O3) into water are presented. Solvation gaseous H2O2 O3 from an airflow bulk vs. electrosprayed microdroplets was measured, wh...

We measured airborne exposures to the biological insecticide Bacillus thuringiensis var. kurstaki (Btk) during an aerial spray program to eradicate gypsy moths on the west coast of Canada. We aimed to determine whether staying indoors during spraying reduced exposures, to determine the rate of temporal decay of airborne concentrations, and to determine whether drift occurred outside the spray z...

Commercially available controls for reducing worker exposure to paint overspray were evaluated in six autobody shops and a spray-painting equipment manufacturer's test facility. Engineering control measures included spray-painting booths, vehicle preparation stations, and spray-painting guns. The controls were evaluated by measuring particulate overspray concentrations in the worker's breathing...

The effects of spray-dried animal plasma in milk replacer without or with the addition of additives containing fructooligosaccharides and spray-dried serum on health, growth, and intake of Holstein calves was measured in two 56-d experiments. In experiment 1, 120 calves were fed milk replacer containing 0 or 20% of crude protein as spray-dried bovine plasma for 42 d and 30 to 60 g/d of additive...

Titanium is widely used for medical purposes. It related to bone repair because of its favorable mechanical properties and biocompatible ability osseointegrate in host tissue. A good lasting connection the implant with tissue possible when there are sufficient conditions grow into pores material, therefore use a porous titanium coating may be helpful solving this problem. In paper, shrouded pla...

Oxides of Nitrogen are the major emission from a diesel engine. It is due to heterogeneous diffusion combustion system with fuel-rich regions, which produce high local temperature around the periphery of the spray where high formation rate of NO is promoted. Various techniques are therefore employed to reduce the NOX emission like EGR, SCR, etc. In this present work a rotating injector is a tec...

The plasma spray technique has been used by several researchers to deposit nanostructured ceramic coatings, but there is no available literature discussing how to fabricate a bulk, freestanding nanostructured component by such a technique. In the current study, net shape nanostructured Al2O3 structures have been fabricated using the plasma spray technique. A detailed characterization of the spr...

A biological pesticide was aerially applied to a hardwood forest – corn field edge in a replicated series of single spray swaths. The drift of small droplets, which remained suspended in the air after each spray swath, was monitored remotely and mapped with the University of Connecticut portable, elastic-backscatter lidar. Plumes of small droplets were tracked which drifted off after every spra...
