In this paper, we explore the noncommutative space-time to revive the idea that gamma-ray excess in the galactic center may stem from the annihilation of particle dark matter. In the noncommutative theory, the
When the ultraviolet light strikes atom of the phosphors (shown here as white dots), it excites their electrons in just the same way that the mercury atoms were excited. This makes the phosphor atoms unstable, so they give off their excess energy as photons—which, this time, happen to be...
Explain why knowing the limiting and excess reagents at each point on the titration curve is important. Why doesn't the indicator affect the titration results in the standardization of NaOH with standard HCl? Discuss the neutralization of acid rain. What has been done so far and how effective ...

This is because the firm operates with excess capacity that cannot be shed. For such a “cash cow” firm, debt value is high because taxable revenues are high. At the same time, the value of growth options is low since the firm is far away from the endogenous investment threshold. The ...

marriage3). Understanding how social and cultural processes affect the genetic patterns of human populations over time has brought together anthropologists, geneticists and evolutionary biologists, and the availability of genomic data and powerful statistical methods widens the scope of questions that ...
If a bank becomes worried about the future, it may decide to increase the level of excess reserves it holds in hopes of avoiding a trip to the Fed's discount window. a. If a large number of banks inc Three individuals received $...
But the proportionality of growth and expression might not always be true. Abundance of the activator Cln3 has been measured as cells grow. Cln3 is non-abundant and unstable, and its measurement is difficult. Three papers found that Cln3 concentration stays about the same when cells grow (...
