Ant‐Nest Corrosion Morphology of Deoxidized High Phosphorous Copper and Oxygen‐Free Copper Tubes Exposed to Formic Acid Vapor

open access: yesMaterials and Corrosion, EarlyView.
Localized corrosion behavior of phosphorus‐deoxidized copper (DHP) and oxygen‐free copper (OFC) was investigated under exposure to formic acid vapor. The corrosion morphology was found to vary depending on the pH of the environment, and it was revealed that the phosphorus contained in DHP influences the pH, thereby affecting the corrosion behavior ...

On Convex Univalent Functions

Canadian Journal of Mathematics, 1970
In what follows, we suppose that ƒ(z) = Σ0∞anzn is regular for |z| < 1. LetandThen (see, for example, [6, pp. 235-236]), for 0 ≦ r < ρ < 1, we have:The following results are well known.

Series of univalent functions [PDF]

open access: possibleMathematical Notes of the Academy of Sciences of the USSR, 1978
We are considering a class S of functions F(z), F(0) = 0, F′(0) = 1 that are univalent and regular in the circle ¦z¦ < 1, and its subclasses s h * and K of starlike functions of order h and of convex functions respectively. Among others, we establish the following results: If F(z)es and 0 < α < 1, then IfF (z) e s (0 < a < 1) and $$\begin ...
