Thanks to the development of new and lower cost portable systems, IRT has become a non-invasive technique that allows for the precise measurement of infrared radiation, and hence spatial variation in body surface temperature, it can be used at less than one metre to investigate specific body ...
Depending on the assumptions made concerning diet, the annual calculated mean effective doses would be reduced as follows: from about 15 mSv (if the dose due to natural background radiation were added, this would result in an annual effective dose of about 17.4 mSv), for a high calorie diet...
ESA's Planck mission has observed the cosmic microwave background radiation and, from that, deduced the amount of matter and dark matter in the universe, the density of matter in the cosmos, and the ways those measurements affect the geometry of the universe. Neil deGrasse Tyson discusses the...
Also, we here considered all threats to birds, while in7 they exclusively focused on wildlife trade, making the results of the two studies not directly comparable. Another difference is that our analyses refer to the entire bird radiation while7 only considered passerine birds (Order Passeriformes...
