The quantum-dot cellular automata (QCA) nano-technique has attracted computer scientists due to its noticeable features such as low power consumption and small size.Many papers have been published in the literature about the utilization of this technology for de-signing many QCA circuits and for presenting logic gates in an optimal structure.The te
In Mediterranean regions, afforested areas were planted to ensure the permanence of land cover, and to protect against erosion and to initiate the vegetation processes.For those purposes, pine species were mainly used; however, many of these stands, without silvicultural treatments for over fifty-sixty years, were in a poor finish line thia cal sta
In Drosophila, post-transcriptional gene silencing occurs when exogenous or endogenous double stranded RNA (dsRNA) is processed into small interfering RNAs (siRNAs) by Dicer-2 (Dcr-2) in association with a dsRNA-binding protein (dsRBP) cofactor called Loquacious (Loqs-PD).siRNAs are then loaded onto Argonaute-2 (Ago2) by the action of Dcr-2 with an
Right heart catheterization was performed on 28 patients beed machine weed suffering from severe rheumatic mitral stenosis.10 were male and 18 female.The ages of the patients ranged from 12 to 45 years.21 of them had a normal sinus rhythm and the other 7 had atrial fibrillation.Information about the severity of symptoms was available in only 16 of
