in the x direction, the water wants to flow in that direction) For a given hydraulic. conductivity, the vertical flow rate depends on the sum of the gravitational potential energy. gradient per unit weight of water (dz/dz =1) and the vertical gradient in soil water pressure.
Origin and spread of the 1278insTATC mutation causing TayâSachs disease in Ashkenazi Jews: Genetic drift as a robust and parsimonious hypothesis. Human Genetics 114 (4): 366â376. pmid 14727180.
About Tay-Sachs Disease: An End to an Incurable Genetic Disease. The availability of JScreen is a promising step in building upon the initial success of Tay-Sachs screening. Traditionally, Tay Sachs carrier screening required blood enzyme testing, but todayâs sequencing method allows highly accurate testing to be performed on saliva.
