The evolutionary precursor of photosynthesis is still under debate, and a new study sheds light.

      När pandemin tog fart våren 2020 var Region Västmanlands beredskap god när det gäller medicinska gaser som syrgas (oxygen). Redan i april 2020 fanns en extra tank flytande oxygen på plats på sjukhusområdet i Västerås och man klarar i dag Socialstyrelsens skärpta krav.
      When the pandemic gained momentum in the spring of 2020, Region Västmanland's preparedness was good concerning medical gases like oxygen. Already in April 2020, there was an additional tank of liquid oxygen in place at the hospital area in Västerås, and today they meet the stricter requirements set by the National Board of Health and Welfare.

Usage notes

  • The term oxygen is rarely used; it primarily appears on gas tubes and canisters for international standardization, as well as a safety precaution to minimize the risk of confusing syre (“oxygen”) with syra (“acid”).
