Turbidity measurements are inexpensive and can be performed rapidly and simply. Therc has bccn a necessity to develope a technique which could bc utiliscd with some degree of confidence to identify certain conditions rclatcd to potentially problcrnalic sugars. Nephelometric turbidity measurements were performed on a number of raw sugars and correlated with filterability dctcrmined routinely usi...

Abstract: In this paper, we study the Nicholson-type delay systems with patch structure and nonlinear density-dependent mortality terms. Under appropriate conditions, we establish some criteria to ensure the permanence of this model. Moreover, we give some examples to illustrate our main results.
