The classical example of thermionic emission is the emission of electrons from a hot cathode into a vacuum (also known as thermal electron emission or the Edison effect) in a vacuum tube. The hot cathode can be a metal filament, a coated metal filament, or a separate structure of metal or carbides or borides of transition metals.
Low confidence regions are areas for which there s a small amount of DNA evidence found in your sample. All ethnicities with predicted percentages of less than 4.5% appear as low confidence regions. Inferior complex is low complex .
I ordered the Ancestry.com DNA test in July. I got my results back last week (it took about 3 weeks to get the results back). The results showed West African 44%, British Isles 29%, Scandinavia 12%, Finnish-Volga/Ural 11%, and uncertain 4%. was certain that Ancestry had mixed up my sample with another. Then 4 months after receiving my âincorrectâ DNA results from Ancestry.com, my 86 year old mother revealed that my biological father was in fact a long time family friend and not the father who raised me. My own mother confirmed the DNA test results.
