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.

The question of nonlinear stability of stationary reactor systems is investigated by two methods. The first method is analytic and sets the theory of nonlinear stability on a firm mathematical basis. The second method makes use of an electrical analogy and is based on the stability criterion stated by Weinberg and Ergen for nonlinear mechanical systems. Both methods deal with reactor systems in which feedback may be nonlinear as well as linear. The effect of delayed neutrons is included in the treatment. The stability conditions previously derived by others are shown to be special cases of the criteria proposed in this paper.
