گیاهان در همزیستی با قارچهای میکوریز آربوسکولار1 (amf) علاوه بر جذب بیشتر عناصر غذایی و آب، می توانند مقاومت خود را در برابر تنشهای محیطی از قبیل شوری و یا خشکی افزایش دهند. تصور می رود حضور برخی از باکتریهای محرک رشد گیاه2 (pgpr) مخصوصاً سودوموناسها در ریزوسفر چنین گیاهانی احتمالاً اثر هم افزایی3 داشته و اثرات مثبت قارچهای میکوریز را تشدید کنند. در این تحقیق گیاه گوجه فرنگی رقم super strain b در...
The Chao matrix formalism allows analytic calculations of a beam’s polarization behavior inside a spin resonance. We recently tested its prediction of polarization oscillations occurring in a stored beam of polarized particles near a spin resonance. Using a 1.85 GeV/c polarized deuteron beam stored in COSY, we swept a new rf solenoid’s frequency rather rapidly through 400 Hz during 100 ms, whil...
Stochastic properties of the long time behavior of a continuously observed (and interactively controlled) quantum–field top are investigated mathematically. Applications to interactively controlled stochastic computer-graphic dynamic systems are discussed. 1 A preliminary shortened draft of this paper is located in the e–print archive of Los Alamos National Laboratories (USA) on Chaos and Dynam...
For better inference of the population quantity of interest, ratio estimators are often recommended when certain auxiliary variables are available. Two types of ratio estimators, modified for adaptive cluster sampling via transformed population and initial intersection probability approaches, have been studied in Dryver and Chao (2007). Unfortunately, none of them are a function of a minimal su...
