Notes on strongly Whyburn spaces
We introduce the notion of a strongly Whyburn space, and show that a space is strongly Whyburn if and only if is Whyburn. We also show that if is Whyburn for any Whyburn space , then is discrete.

We give a characterization of normal and countably paracompact spaces via continuous set-avoiding selections.
A sufficient condition for the pseudo radiality of the product of two compact Hausdorff spaces is given.
