Another exam that utilizes ultrasound is Doppler fetal monitoring. This test is typically performed during the last trimester on women who suffer from gestational diabetes.

The test will determine if Baby is getting enough blood. An ultrasound is considered safe for both you and your baby when it’s used for medical purposes.

History Galton whistle, one of the first devices to produce ultrasound Acoustics , the science of sound , starts as far back as Pythagoras in the 6th century BC, who wrote on the mathematical properties of stringed instruments. Echolocation in bats was discovered by Lazzaro Spallanzani in , when he demonstrated that bats hunted and navigated by inaudible sound, not vision.
Francis Galton in invented the Galton whistle , an adjustable whistle that produced ultrasound, which he used to measure the hearing range of humans and other animals, demonstrating that many animals could hear sounds above the hearing range of humans. The first technological application of ultrasound was an attempt to detect submarines by Paul Langevin in The piezoelectric effect , discovered by Jacques and Pierre Curie in , was useful in transducers to generate and detect ultrasonic waves in air and water.

References Dating the Beginning of Pregnancy One of the most important aspects of obstetrical care is to date, as precisely as possible, the beginning of pregnancy so that the estimated time of arrival ETA can be calculated sometimes referred to as the estimated date of confinement — EDC. And yet, even with all of the available technology, one of the puzzles of modern obstetrics, is that the obstetrician has not yet learned how to accurately date the beginning of a pregnancy.
Pregnancy can be measured in two different ways. The most common and most often used in clinical obstetrics is the measurement of the gestational age of the pregnancy. The gestational age of the pregnancy is measured from the first day of the last menstrual period. In this way of dating the pregnancy, the pregnancy is 40 weeks in duration on average instead of the actual 38 weeks.
In other words, it dates the pregnancy, on average, two weeks longer than it is. The other way of measuring the dates of the pregnancy is to measure the fetal age. The fetal age of the pregnancy is measured from the time of conception or the estimated time of conception ETC.

Print Radiocarbon Dating and Archaeology Radiocarbon dating lab scientists and archaeologists should coordinate on sampling, storage and other concerns to obtain a meaningful result. The sample-context relationship must be established prior to carbon dating. The radiocarbon dating process starts with measuring Carbon , a weakly radioactive isotope of Carbon, followed by calibration of radiocarbon age results to calendar years.
History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past. Historians can tell what cultures thrived in different regions and when they disintegrated. Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.
Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences. It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself. Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology , archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.
Radiocarbon dating has been around for more than 50 years and has revolutionized archaeology. Carbon 14 dating remains to be a powerful, dependable and widely applicable technique that is invaluable to archaeologists and other scientists.
