symptoms and chest CT findings was found. (4) Conclusions: More than half of the patients with initially mild or moderate infection showed findings on chest CT at follow-up. Respiratory symptoms, however, were not related to any chest CT finding. We, therefore, do not suggest routine chest ...
Having more (or fewer) neutrons than the ideal can make an atom so unstable that it spontaneously changes into a different, more stable atom or isotope by giving off some of its unwanted, subatomic particles or energy. Thus, carbon-14 atoms spontaneously (albeit very slowly) turn into ...

The isotopic fractionation of carbon in mangroves is related to the ratio of intercellular (Ci) to ambient (Ca) partial pressure of CO246. Consequently, fluctuations inδ13C may indicate shifts in the Ci/Caratio due to environmental changes, such as alterations in salinity46. Mangroves exhibit ...
Overall, they can work out significantly cheaper: an analysis by Vincentric found 42 US hybrids (roughly half of those studied) were more cost-effective then their gasoline counterparts. How does a plug-in hybrid work? A hybrid car is like two cars in one: it has a conventional gasoline ...
How many years would it take for an isotope to be completely non-reactive if the isotope had a half life of 200 years? How would you figure this problem when you are not given a starting amount of sub How did Dalton and Rutherford's work ...
What are the properties of protons, neutrons, and electrons. How are they important to the atomic structure? How does the half-life method of an isotope works in radiometric dating? Explain the phosphorus cycle. How do we use isotopes to date objects?
Trait Values, Not Trait Plasticity, Best Explain Invasive Species' Performance in a Changing Environment Virginia Matzek* Department of Environmental Studies and Sciences, Santa Clara University, Santa Clara, California, United States of America Abstract The question of why some intro...
People who went through at least the first half of the math undergraduate program will most likely understand. In the general population, I guess, saying '100 % probability' would work much better than 'probability 1', but still people can get quite upset when something with 99 % probability...
The most important explanatory variables were MAT and tree size, with minor contributions of management and plant functional type depending on mortality cause. Our results provide a basis to improve the representation of dead wood decomposition in carbon cycle assessments. Keywords: standing dead wood;...
