One of the most successful of these techniques has proved to be X-ray fluorescence imaging, through which the iron in the ink is revealed, even under a forged overpainting.

Lister was able to quickly reduce infection rates, a reduction that was further helped by his subsequent introduction of the techniques of Robert Koch ( such as the Steam Steriliser, which proved more successful than the carbolic acid spray that Lister had been using previously ) to sterilize equipment, have rigorous hand washing and a later implementation of rubber gloves.

# The same basic techniques have proved applicable to a wider class of problems ( e. g., the study of function spaces ).

Currently, the McDonald criteria focus on a demonstration with clinical, laboratory and radiologic data of the dissemination of MS lesions in time and space for non-invasive MS diagnosis, though some have stated that the only proved diagnosis of MS is autopsy, or occasionally biopsy, where lesions typical of MS can be detected through histopathological techniques.

Theoretically, enriching uranium was feasible through pre-existing techniques in physics ( e. g., modifying particle accelerator technology ), though it proved difficult to scale to industrial levels and was extremely costly.

The problem with type B is that it relies on the program being able to decide which moves are good enough to be worthy of consideration (' plausible ') in any given position and this proved to be a much harder problem to solve than speeding up type A searches with superior hardware and search extension techniques.

The oblique projection techniques proved difficult to program and were time consuming as well.

Mansfield also proved ahead of her time in her adoration of Russian playwright and short story writer Anton Chekhov, and incorporated some of his themes and techniques into her writing.

The scholarly history of the Deuteronomic history parallels that of the Pentateuch: the European tradition history school argued that the narrative was untrustworthy and could not be used to construct a narrative history ; the American Albright school asserted that it could when tested against the archaeological record ; and modern archaeological techniques proved crucial in deciding the issue.

Andrew Wiles proved the modularity theorem for semistable elliptic curves, which was enough to imply Fermat's last theorem, and Christophe Breuil, Brian Conrad, Fred Diamond, and Richard Taylor extended his techniques to prove the full modularity theorem in 2001.

They became farmers and used intensive German farming techniques that proved highly productive.

A well-known example was the development of analytic geometry, which in the hands of mathematicians such as Descartes and Fermat showed that many theorems about curves and surfaces of special types could be stated in algebraic language ( then new ), each of which could then be proved using the same techniques.

However, there was nothing to prevent the successful employment of wet flies on these chalk streams, as George Edward MacKenzie Skues proved with his nymph and wet fly techniques.
