When an ultrasound is performed, measurements of the head, abdomen, thigh, and amount of amniotic fluid are done.
These measurements are computed automatically in the ultrasound machine’s software.
Each document was produced at different moments using a different ink stroke pressure, factors that may alter the results and lead to dating errors.
During the natural ageing process of each sample, which had a known age, the research team analysed the evolution in the various volatile components.
That is why it is very useful for documents that have been signed as it is possible to compare whether the body of the document, if it has been written by hand, is as old as the signature.
Or else it is a very useful tool to date contracts, settlements, wills or other documents.
Ultrasound has become so helpful that obstetricians now refer to the time before it was used routinely as “the olden days.” We use it to diagnose twins early on; we use it to document appropriate growth as the pregnancy progresses; we use it to determine fetal health; and we use it to guide conversion of breech to vertex (head-first) position and to guide amniocentesis.
So Datink offers a more accurate, less damaging, less intrusive and less harmful result. The excavation work has demonstrated that the settlement, which is now home to the small Kurdish ...The problems Determining the age of a document to find out whether it is authentic is a task influenced by the type of paper on which it has been written, the pressure of the stroke -the amount of ink deposited when the writing was done- or even the technique used.Until now, document dating methods have been able to indicate whether the writing was relatively new (less than 90 days) or older (over two years), yet this chronological accuracy is insufficient in certain cases, above all in judicial ones.Nevertheless, this methodology is a pilot experience that requires further in-depth research when it comes to evaluating the limits of the applicability of the various inks and makes of ballpoint pens, thus reducing its potential limitations. Historical research using forensic fingerprinting techniques on the wax seals of thousands of medieval documents will reveal new insights into 12th to 14th century British society, help determine how ...As Luis Bartolomé pointed out, "what is interesting about this method is that it can more accurately determine the age of the stroke produced by the ballpoint pen.
