The phrase "a arc" is not correct in written English.
The correct form is "an arc" due to the vowel sound that follows the article.
Example: "The artist drew an arc in the sky with her brush."
Alternatives: "a curve" or "a segment."
Still, Mr. da Silva responded to the space agency's report with tough measures, including imposing credit restrictions on those found to be involved in illegal forest-clearing and creating a Arc of Fire, a multi-agency police operation that conducts surprise raids to catch illegal loggers.
Furthermore, this coating can effectively resist the arc ablation (120 A arc currents) within 7 s.
Figure 5 Cl versus F in, (A) arc melt inclusions, slab and mantle wedge, (B, C, and D) predicted melts.
We have found that all the HAuCl4 molecules will reduce after about 4 min arc duration and in 15 A arc current.
The optical image of as-prepared samples at 15 A arc current and 1 min arc duration, which is pale red, also verifies this result (Figure 4b).
A surface plasmon resonance was observed around 520 nm based on optical absorption spectroscopy of as-prepared samples at 15 A arc current in HAuCl4 solution.
In this work a 15-A arc current was applied between two titanium electrodes in HAuCl4 solution.
Films that formed in a 30-s exposure at the beginning of a 175-A arc, when it operated in the cathode spot mode, were heavily contaminated with MPs.
In this study, the effort was to design and synthesize five new members of alkoxy substituted thiourea derivatives (3a 3e) featuring general formula of A-ArC(O NHC(S NHAr-D in which A repreS NHAr-De methoxy group and D as –OCnH2n+1 (alkoxyl group, where n = 6,7,8,9, and 10) have been successfully desinned, prepared, characterized, and evaluated for anti-amoebic activities.
Workplace A also manufactured SWCNTs using an arc discharge process.
PRS was a recipient of an ARC fellowship.
