Application of the exact operational matrices for solving the Emden-Fowler equations, arising in ‎Astrophysics‎

The objective of this paper is applying the well-known exact operational matrices (EOMs) idea for solving the Emden-Fowler equations, illustrating the superiority of EOMs over ordinary operational matrices (OOMs). Up to now, a few studies have been conducted on EOMs ; but the solved differential equations did not have high-degree nonlinearity and the reported results could not strongly show the...

بررسی تاثیر وضعیت نیمه نشسته ومدت زمان آن برروی نتایج گازهای خون شریانی بیماران تحت تهویه مکانیکی بستری در ICU عمومی

Position changing with blood distribution to different portions of lung    can produce V/Q mismatch, and finally extend to oxygenation disruption.    Thus, if position changing  is done’ neglecting the patients’ pulmonary    problem types, not only does it fail to cause oxygenation improvement, but    it also induces gas exchange im...

مقایسه تهوع و استفراغ ضمن همودیالیز در دو وضعیت خوابیده به پشت و نیمه نشسته

Background and purpose: The most common treatment used for end-stage renal disease (ESRD) is hemodialysis. Although, this treatment caused may promote longevity, however, many complications may occur, such as nausea & vomiting. Body position during hemodialysis has an effect on nausea & vomiting episodes, patients who may lay in Semi fowler position during hemodialysis are able to communicat...
