State-level data show the difference in crude oil API gravity in different parts of the country. For example, oil produced in Texas has a relatively broad distribution of API gravities, with most production ranging from 30â50 degrees API. Oil produced in North Dakota tends to be light (less dense).
Margot Frank, Anne's older sister, died of typhus in Belsen at the age of 19 in March 1945 (Exact date unkown).
Anne Frank died of typhus before Bergen-Belsen was liberated by the British on 15 April 1945. The precise date of her death is not known, but it was probably during the first two weeks of March. Her body was heaped up with hundreds of others in a pile beside the barracks. She has no known grave. But her diary remained.
