This paper presents analytical solutions and simulations for pressure transient behavior of the partially penetrating wells (PPWs). The Newman’s product method was adopted to develop the basic instantaneous source functions which characterize the response of PPWs. These results were obtained based on the solution of fully penetrating wells (FPWs) and they were presented in Laplace domain. Furth...
hyperbilirubinemia at neonatal period is one of the major deteriorating factors of the auditory system. if left untreated, it may cause certain cerebral damage. this study aims to evaluate the impact of hyperbilirubinemia on the hearing of neonate. this study was conducted on 35 newborn babies with jaundice (bilirubin more than 20 mg/dl). auditory brainstem response (abr) and transient evoked o...
An analytical expression is presented for the voltage response including the transient voltage for a simple ~i.e., no concentration gradients! porous electrode model subject to a sinusoidal input current density. The transient voltage response as a function of the frequency, exchange current density, and double layer capacitance is studied independent of the periodic ~steady state! voltage resp...
The transient hyperaemic response in the middle cerebral artery blood flow velocity on the release of brief compression of the ipsilateral common carotid artery has been validated as an indicator of cerebral autoregulation. We evaluated, in three stages, the effect of experimental factors such as duration of compression of the common carotid artery and magnitude of the decrease in blood flow ve...
our aim was to report techniques and our experience in one-stage angioplasty and stenting of ostium of left common carotid and left internal carotid arteries in an octogenarian man with transient ischemic attack, who was completely recovered from neurologic insults short time after the procedure. an 81-year-old man presented with a transient ischemic attack. neurologic examination showed left s...
