Fatigue crack growth measured by the Electric Potential Drop Conceptual Upgrade Ing. D. Slagter Apeldoorn The Netherlands (c) 2026 22-07-26 ------------ 2, D. Slagter: Yes, On Friday 24-07-2026: On air. 24-07-26 ------------ 149, Henry Baker: Hi, I was looking over your website and noticed a few specific areas where optimization could boost your Google rankings and attract higher-quality leads. I have put together a brief SEO strategy and pricing proposal designed to help scale your organic growth. Would you be open to reviewing it? Best regards, Henry 29-07-26 ------------ 157, D. Slagter: Dear Henry, 149, Thank you for your message on this Guestbook. But understand my position. The Bros project ended in the 70´s properly. But my sub-project was, to my opinion, not run until the end of instrumental possibilities. Decades later I finished this sub-project on a private basis at home. Including modern concepts. Like matrix math curve fitting by spread-sheet analysis. The use of a Single Board Computer. And single IC laboratory grade amplification of electric signals. Done to empty my head, results free to use for everyone. I have no commercial intentions. With : ´Fatigue crack growth´, and: ´Slagter´, you will find me on Google page one. That´s enough, no additional optimization needed. Sincerely, Dick Slagter. 29-07-26 ------------
