how to calculate blp of teh rock phosphate

Phosphorite, also called phosphate rock, rock with a high concentration of phosphates in nodular or compact masses. The phosphates may be derived from a variety of sources, including marine invertebrates that secrete shells of calcium phosphate, and the bones and excrement of vertebrates.. The thickest deposits of phosphorite form in areas characterized by carbonaceous shale and chert.

Studying flies and mice, Jasper and colleagues demonstrate that repeated regenerative episodes result in the loss of tissue stem cells (SCs) due to the transient activation of the growth regulator mTORC1 during SC activation. Pharmacological inhibition of mTORC1 can prevent this loss and limit the age-related decline in SC numbers.
