Roberto Caldeyro-Barcia studied fetal health in Uruguay during the second half of the twentieth century. Caldeyro-Barcia developed Montevideo units, which are used to quantify intrauterine pressure, or the force of contractions during labor. Intrauterine pressure is a useful measure of the progression of labor and the health of a fetus [3]. Caldeyro-Barcia?s research on fetal health often contr...

Phase change of pore fluid (boiling/condensing) in rock cores under conditions representative of geothermal reservoirs results in alterations of the electrical resistivity of the samples. In fractured samples, phase change can result in resistivity changes that are more than an order of magnitude greater than those measured in intact samples. These results suggest that electrical resistivity mo...

New eclogite localities and new Ar/Ar ages within the Western Gneiss Region of Norway define three discrete ultrahigh-pressure (UHP) domains that are separated by distinctly lower pressure, eclogite facies rocks. The sizes of the UHP domains range from c. 2500 to 100 km; if the UHP culminations are part of a continuous sheet at depth, the Western Gneiss Region UHP terrane has minimum dimensions...

Cricoid pressure (CP) was introduced into anaesthetic practice based on a single case series that lacked information on the force applied and on the method of application. Up to now, there are no controlled, prospective randomised trials which document that CP pressure reduces the incidence of regurgitation of gastric content and pulmonary aspiration. On the other hand, numerous studies have sh...

Isothermal hydrogen absorption properties of the ball milled mixture of 3Mg(NH2)2 and 8LiH after dehydrogenation at 200 °C under high vacuum were investigated at two different temperatures of 150 and 200 °C. The pressure –composition isotherm (PCT) curve at 200 °C revealed a two-plateaus-like behavior, while the PCT curve at 150 °C showed a single-plateau-like behavior. The hydrogenated phases ...

The steering torque at the handwheel, necessary to steer a car at zero speed, is discussed. Measurements made on a tyre alone on a static rig and measurements made on a car in normal trim are complemented by a mathematical system model. The model uses parameter values deriving partly from the tyre rig results, partly from the car specification and partly from the car results. It provides simula...

The objective of the present research is to explore the causes of microventing, a phenomenon generally occurring in cohesive sediments during their deposition and consolidation. Microvents are characterized by volcano-like formations, remnants of the expulsion of fluid and sediment along a vertical channel through the sediment layer. The size of these vent formations ranges from the order of mi...

Recently, the percentage of people with hypertension is increasing, and this phenomenon is widely concerned. At the same time, wireless home Blood Pressure (BP) monitors become accessible in people’s life. Since machine learning methods have made important contributions in different fields, many researchers have tried to employ them in dealing with medical problems. However, the existing studie...

Little attention has been given to assessing risk factors for cerebrovascular disease (CBVD) and less has been given to relating long term changes in blood pressure (BP) to CBVD occurrence. In the Manitoba Study a cohort of 3,983 North American men (predominantly between 25-34 years of age at entry in 1948), measured 5 times during the 26 year observation period from 1948 to 1974, was related t...
