soil affected by salt (nacl) is a major problem worldwide and in areas with potential agriculture; lands in many countries are not enough to support crop production. the development of salt tolerant cultivars would be enhanced by better understanding of the genetic control of tolerance to salt stress. a new cereal, tritipyrum, a range of amphiploids between triticum spp. and thinopyrum spp....

Spontaneous combustion of coal is one of the most horrifying hazards in coal industries, especially in underground coal mines. Thus having a prior knowledge about the occurrence of this phenomenon in underground coal mines is of crucial importance in preventing this process, loss of life, huge economic loss, and environmental pollution. The aim of this work is to determine the spontaneous combu...

background: neuroectodermal tumors (pnet) are malignant small cells neoplasm mainly occurring in children but can occur at any age. extensive bleeding into the pleural cavity is rare in children. hemothorax would be compatible with a variety of congenital anomalies including sequestration, patent ductus artreiosus, and pulmonary arteriovenous malformation. case report: a 2.5-years old girl who ...

Sensory deafferentation resulting from the loss of photoreceptors during retinal degeneration (rd) is often accompanied by a paradoxical increase in spontaneous activity throughout the visual system. Oscillatory discharges are apparent in retinal ganglion cells in several rodent models of rd, indicating that spontaneous activity can originate in the retina. Understanding the biophysical mechani...
