We love this tradition. 🥹 Last night, some of Japan’s supporters stayed behind to help clean up the stadium after their match against the Netherlands in Dallas. Class act. 🇯🇵 #Olympics #FIFAWorldCup

Wstrząsające… warkoczyki, buciki - relacja z ekshumacji w Ostrówkach z roku 2011. W trakcie prac ekshumacyjnych odnaleziono szczątki co najmniej 231 osób (głównie kobiet i dzieci), które zostały zamordowane przez oddziały Ukraińskiej Powstańczej Armii (UPA) 30 sierpnia 1943 roku.

"I should not like to leave an impression that all structural problems can be settled by X-ray analysis or that all crystal structures are easy to solve. I seem to have spent much more of my life not solving structures than solving them." - chemist Dorothy Crowfoot Hodgkin

Thanks for the feedback. Yes, I mistakenly wrote the antenna name incorrectly. The correct name is “egg-beater”. I based my work on the original #ON6WG / #F5VIF design: on6wg-f5vif.online/Doc/Anten… Later, other articles also appeared, for example this one: amsat.org/wordpress/xtra/Get…
