Subsynchronous resonance (SSR) problems appeared due to resonance between the turbine and the series capacitor on transmission line is damped by installing superconducting magnetic energy storage (SMES) unit which the parameters are optimized by quantum behaved particle swarm optimization (QPSO). The proposed objective function is comprehensive damping index (CDI) of SSR damping. To accommodate...

روند تحولات قیمت نفت خام نشان می دهد که از سال 1950 تاکنون چندین بحران شدید نفتی در سالهای مختلف 1973)، 1979، 1986، 1998، 2003، (… در بازار نفت وجود داشته است. این نوسانهای شدید قیمت نفت خام از پدیده های مهم اقتصادی و سیاسی تلقی گردیده، مناظرات و مباحثات علمی بی شماری را برانگیخته است. در یک بازار رقابتی یا انحصاری، قیمتهای واقعی متناسب با افزایش یا کاهش هزینه های نهایی تغییر می یابد و اصولا اف...

The starvation survival response (SSR) of Listeria monocytogenes EGD is induced under glucose- or multiple-nutrient-, but not amino-acid limitation. 0.01-0.2% of the population remain viable even after 20 d and the survivors show a reduced cell size and increased cross-protection to several environmental stresses. The development of the SSR may therefore be important in L. monocytogenes surviva...

ABSTRACT Isolates of Puccinia triticina collected from common wheat in the Central Asia countries of Kazakhstan, Uzbekistan, Tajikistan, and Kyrgyzstan and the Caucasus countries of Azerbaijan, Georgia, and Armenia were tested for virulence to 20 isolines of Thatcher wheat with different leaf rust resistance genes and molecular genotype at 23 simple sequence repeat (SSR) loci. After clone corre...

Background Eucalypts are the most widely planted hardwood trees in the world, occupying globally more than 18 million hectares, as an important source of carbon neutral renewable energy and raw material for pulp, paper and solid wood. Intensive planting programs of Eucalyptus grandis have been carried out in the Argentinian Mesopotamia. Linkage maps are useful tools for quantitative trait loci ...

Introduction Both B-mode ultrasound and contrast-enhanced ultrasound (CEUS) are well established procedures when diagnosing traumatic splenic ruptures (TSR). To date, there are no data about CEUS patterns in spontaneous splenic ruptures (SSR). It remains unknown whether TSR and SSR differ with respect to clinical characteristics, B-mode and CEUS characteristics. Patients and Methods Between 1...

In this paper we study some standard problems of SSR (Secondary Surveillance Radar), relating to improving the detection performance of the conventional SSR and Mode S replies in SSR FRUIT environment. We present the algorithm that consists of a conventional two-dimensional CFAR BI processor combined with the estimator of the FRUIT parameters, which is necessary for automatic selecting of the a...

Sparse support recovery (SSR) is an important part of the compressive sensing (CS). Most of the current SSR methods are with the full information measurements. But in practice the amplitude part of the measurements may be seriously destroyed. The corrupted measurements mismatch the current SSR algorithms, which leads to serious performance degeneration. This paper considers the problem of SSR w...

Segregating F4 families from the cross between drought sensitive (Yecora Rojo) and drought tolerant (Pavon 76) genotypes were made to identify SSR markers linked to leaf chlorophyll content, flag leaf senescence and cell membrane stability traits in wheat (Triticum aestivum L.) under water-stressed condition and to map quantitative trait locus (QTL) for the three physiological traits. The paren...

چوب مرغوب و میوه عالی گردو هر دو از لحاظ اقتصادی دارای ارزش بالایی هستند. به همین دلیل این گونه درختی از گذشته تا امروز به شدت مورد بهرهبرداری قرار گرفته تا جایی که در قانون حفاظت از جنگلها و مراتع تحت عنوان گونه حفاظت شده معرفی شده است. عملکرد گونههای گردو، به ویژه j. regia در سال مرطوب افزایش و در سال خشک کاهش مییابد. تنش خشکی به عنوان مهمترین تنش غیر زیستی نقش مهمی در کاهش تولیدات گیاهی در ج...
