In the present article, we describe the validation of a new non-invasive method for measuring blood pressure (BP) which also enables to determine the three BP values: systolic, diastolic and mean value. Our method is based on the pulse transit time (PTT) measurement along an artery directly at the BP cuff. The accuracy of this method was evaluated by comparison with the direct simultaneous meas...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Nowadays, Electrical Discharge Machining (EDM) has become one of the most extensively used non-traditional material removal process. Its unique feature of using thermal energy to machine hard to machine electrically conductive materials is its distinctive advantage in the manufacturing of moulds, dies and aerospace components. Howevere, EDM is a costly process and hence proper selection of its ...
For their appropriate temporal resolution, scintillator detectors are used in the Alborz observatory. In this work, the behavior of the scintillation detectors for the passage of electrons with different energies and directions were studied using the simulation code GEANT4. Pulse shapes of scintillation light, and such characteristics as the total number of photons, the rise time and the fallin...
We derive general expressions of pulse propagation time on warped membrane to analyze the cell shape influence on signal processing. In particular, we consider round (Purkinje-like) and cone (pyramidal) cell shapes to compare the theoretical results with computational ones obtained by the two-dimensional membrane potential computation. We also take into account the channel type varieties (Squid...
Background and Objectives: Pulse oximetry is the most common technique for monitoring hemoglobin oxygen saturation (SpO2). Different colors and brands of nail polish may cause disturbance in the reading and interpretation of oxygen saturation. The aim of this study was to determine the effect of different colors of nail polish on oxygen saturation measured by pulse oximeter. Methods: Thirty he...
surface roughness is one of the most important parameters that plays very critical role in determining the quality of engineering components. a good surface quality resulting in improve of fatigue strength, corrosion and wear resistance of the workpiece. on the other hand, increasing cutting speed and decreasing time of machining are desirable for manufacturers in order to reduce costs and incr...
cholecystokinin (cck), a peptide hormone found in the gut, is the most abundant peptide neurotransmitters in the brain, and its acute effects on the brain activity have been shown. in this study we aimed to evaluate the acute effects of cck on short-term synaptic plasticity in the dentate gyrus (dg) of the rat hippocampus. via stereotaxic surgery, the stimulating and the recording electrodes we...
