SARS-CoV-2 variant biology: immune escape, transmission and fitness
Nature Reviews Microbiology, 2023 In late 2020, after circulating for almost a year in the human population, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exhibited a major step change in its adaptation to humans. These highly mutated forms of SARS-CoV-2 had enhanced rates

Density Assessment of Different Metals and Alloys by Gamma-Ray Transmission Technique via Using Co-60 Radioactive Source [PDF]
Journal of Physical Science and Application, 2017 In this study, density measurements were observed by using gamma transmission technique. Co-60 gamma emitter was used as gamma radioisotope source. Regarding the gamma-ray transmission method, initial radiation intensity (I0) and radiation intensity (I ...

Transmission of SARS-CoV-2 in free-ranging white-tailed deer in the United States
Nature Communications, 2023 SARS-CoV-2 is a zoonotic virus with documented bi-directional transmission between people and animals. Transmission of SARS-CoV-2 from humans to free-ranging white-tailed deer (Odocoileus virginianus) poses a unique public health risk due to the ...

Science and Technology Development Journal - Natural Sciences, 2021 In this study, we propose an approach using the gamma transmission technique based on the combination of the experimental and simulated data for determining the percentage concentration of the acid solution. The experiment consists of a collimated 137Cs radioactive source emitting a narrow gamma beam of 662 keV and a NaI(Tl) detector.
