What’s in your Dubai chocolate? Nuclear scientists test pistachios for toxins
For the uninitiated, Dubai chocolate is a candy bar filled with pistachio and tahini cream and crispy pastry recently popularized by social media influencers. While it’s easy to dismiss as a viral craze now past its peak, the nutty green confection has spiked global pistachio demand, and growers and processors are ramping up production. That means more pistachios need to be tested for aflatoxins—a byproduct of a common crop mold.

A previous work on the closed-loop dynamics of nuclear rocket engines with bleed turbine drive3 is modified to study the engine dynamics using a topping turbine system. Root locus considerations show that the response characteristics of the two engine systems should be similar, although the topping turbine system has a faster initial response but slower asymptotic response. These conclusions are corroborated by analog simulation of the non-linear dynamic equations.
