Problem: Genetic studies on Ashkenazim have been conducted to determine how much of their ancestry comes from the Levant, and how much derives from European populations. These studies—researching both their paternal and maternal lineages—point to a significant prevalence of ancient Levantine origins. But they have arrived at diverging conclusions regarding both the degree and the sources of their European ancestry. These diverging conclusions focus particularly on the extent of the European genetic origin observed in Ashkenazi maternal lineages.
Genetic studies on the Ashkenazim have tried to determine how much of their ancestry is derived from European populations and from where?
The answer is the following: the Levant

Problem: These motors were originally invented to drive the capstan(s) of magnetic tape drives in the burgeoning computer industry, where minimal time to reach operating speed and minimal stopping distance were critical. Pancake motors are still widely used in high-performance servo-controlled systems, robotic systems, industrial automation and medical devices. Due to the variety of constructions now available, the technology is used in applications from high temperature military to low cost pump and basic servos.
For what type of military applications are pancake motors currently used?
The answer is the following: high temperature
