Pulse oximetry (oxygen saturation monitoring) has markedly improved medical care in many fields, including anesthesiology, intensive care, and newborn intensive care. In obstetrics, fetal heart rate monitoring remains the standard for intrapartum assessment of fetal well being. Fetal oxygen saturation monitoring is a new technique currently under development. It is potentially superior to elect...

Long-term monitoring of central haemodynamics with implanted monitoring systems might be valuable in managing heart failure patients. Such systems offer an opportunity for repeated 'semi-invasive' cardiac output determinations according to the Fick principle. Five patients, four with chronic heart failure and one with chronic pulmonary disease, underwent supine exercise testing during cardiac c...

There has been little interest in the application of hydraulic fracture treatment in Iranian oil fields, thanks to the primarily suitable production rates of the vast oil fields. In this paper, hydraulic fracturing treatment was simulated by different models for a carbonate reservoir in the southwest of Iran. Suitable pay zones were nominated based on the lithology, water-oil saturation, geomec...

This paper reviews the applications of in-situ health monitoring and prognostic sensors with the focus on those in electronic systems. It provides an insight into the issues of utilizing in-situ sensors in electronic systems for health monitoring and prognostics. Those issues are discussed in comparison to those for mechanical systems and structures. This paper also introduces a physics-of-fail...

The author discusses state-of-the-art technology for patient monitoring in office-based anesthesia. New technology includes bispectral index monitoring to evaluate the depth of anesthesia, signal extraction for more accurate oxygen saturation monitoring, and online S-T segment analysis for monitoring multiple electrocardiographic leads.

The amount of oil together with the water Originally in Place (OIP), makes up liquid phase heavy reservoir systems. This present pores system is known as saturation, plays a vital role improving recovery through In-Situ Combustion (ISC) process. acts fuel generating thermal energy required for viscosity reduction and supports formation an enlarged condensation zone that aids higher mobility low...

Accurate estimation of saturation flow rate is a prerequisite for accurate estimation of level of service and delays of signalized intersections. Saturation flow rate of intersections depends on many factors, including traffic behavior and culture. One of the important problems of traffic behavior in Iran is the violation of law at the physical region of intersections. The main purpose of this ...

A field experiment was established in a high elevation red spruce (Picea rubens Sarg.) - balsam fir (Abies balsamea) forest on Mount Ascutney Vermont, USA in 1988 to test the nitrogen (N) saturation hypothesis, and to better understand the mechanisms causing forest decline at the time. The study established replicate control, low and high dose nitrogen addition plots (i.e., 0, 15.7 and 31.4kgNH...
