Also, etched in stone. Definite, fixed, as in We may choose to stay longer-our plans aren't cast in stone, or When Carl sets an agenda you can safely assume it's etched in stone. Both expressions allude to sculpture, with the first, from the early 1500s, using the verb cast in the sense of pouring and hardening some material into a final form, and the second cutting or corroding a permanent design.

Another indicator for nanometer size cracks along the trench was found in a second etch experiment with BOE.
Some studies have demonstrated that chlorhexidine digluconate solutions at concentrations ranging from 0.02 to 2% can inhibit metalloproteinases and reduce solubility of collagen fibers in an aqueous environment, and that its action on the etched dentine does not negatively influence microtensile bond strength of adhesive systems; on the contrary, it has been proven that besides their antimicrobial effect they prevent or slow down the degradation of collagen fibers exposed at the base of the hybrid layer by action of the metalloproteinases when applied after acid etching during etch-and-rinse adhesive systems; this favors dentine adhesion in the long run without cytotoxic effects.
This can be verified in Figure 7, where only a small part of the silicon chip around the position [DELTA]y is etched. When the etched area is under the feeding, the gain is up to 2 dB better than when it is under the ends of the antenna.
The etch solution of six parts of 40% [NH.sub.4]F to 1 part of 48% HF was used in our studies.
Here tungsten oxides and other dirt are etched off and removed thus reducing resistance of the etched surface to a minimum.
The aim of this study was, therefore, to compare the clinical effectiveness of a non-rinse conditioner with conventional acid etch bonding for enamel preparation prior to FS placement.
The global Plasma Etch System market was valued at $XX million in 2018, and analysts predict the global market size will reach $XX million by the end of 2028, growing at a CAGR of XX% between 2018 and 2028.
Aaron Ashmore, owner of Etch & Pin, said: "Lady Godiva is perhaps the Coventry icon most known around the world, so it only felt right that we recognise her importance to the city in one of our collectable pin badges."
The result of these changes and improvements is the overall copper thickness to final etch is reduced from approximately 40[micro]m to approximately 27[micro]m.
The samples were allocated on random basis into 2 groups: (Group 1) The acid-etched group (control), which consisted of 25 premolar teeth which were etched using a 37% phosphoric acid gel (ExciTE F, Ivoclar Vivadent AG, FL-9494 Schaan/Liechtenstein) for 30 seconds, rinsed thoroughly with water, and dried in oil-free air until the enamel surface exhibited a frosty chalky appearance.

No significant difference was found between etch and rinse group and phosphoric acid preetched Filtek P90 group; both were significantly higher than that of Filtek P90 self-etching and the double self-etch primer application.
Meanwhile, many researchers show that tight and durable bonding to enamel and dentin can be achieved by acid etch role, such as 30-40% phosphoric acid.
These solutions rely on the difference in etch rate between <100> and <111> oriented planes (Figure 1) and result in random, upright micrometer-scale pyramids on a <100> oriented surface.
