This sonogram is used to determine fetal anomalies, the baby’s size and weight, and also to measure growth to ensure that the fetus is developing properly. By the 20th week of pregnancy, the baby can weigh up to 11 ounces and measure 10 inches outstretched. The fetus has fingerprints, tiny arms and legs, and the genitalia is often formed. The rate of growth from the 20th week until the 40th week will increase exponentially.

Basically, the technician or the doctor will be looking for any signs of slower than normal development. The skeleton should be hardening at this point and the sex of the baby may be visible. In many cases, the baby may have their legs crossed or be facing away from the abdomen and thus the sexual organs will not be visible during the anatomy ultrasound.

During the procedure gel is smeared to the belly area to ensure good contact between the skin and transducer the device that emits ultrasonic waves.

The transducer is placed on the belly and is rolled back and forth while internal images can be seen on a monitor next to the technician. In earlier scans the sonographer technician only takes 8 or 12 images, with this scan 40 or 50 may be taken. Images Taken During The Scan Head and Brain A cross section of the head is taken and with this measurements are taken just above the ears to get the circumference.

Spine A cross-sectional view of the spine is taken, this helps to identify spina bifida. Internal Organs The baby’s stomach, kidneys and bladder are examined for any blockages. The sonographer checks that all the organs are present and in the right position. The umbilical cord is checked, there should be 2 arteries and 1 vein going through it.

An Anglo-American team found large variations in levels of the carbon isotope, used as the basis of carbon dating, preserved in a 19in stalagmite recovered from a submerged cave in the Blue Holes of the Bahamas, limestone caverns created when sea levels were nearly ft lower than today.

These findings suggested dramatic changes in the amount of radioactive carbon in Earth’s atmosphere during the last Ice Age, much greater than previously thought, probably as a result of changes in the strength of the planet’s magnetic field. The field shields Earth from cosmic rays that create carbon in the atmosphere, altering levels of the isotope during the past 45, years. Radiocarbon dating, which depends on the steady decay of carbon , is less reliable if an artefact is older than 16, years.
