aleap month of 30 days) is added for the same reason that leapdaysare added to our solar calendar---to keep up to the exact solar orbit of 365.2422 days in a (solar) year. Notice that a leap month may occur on any one of the above three "time" slots, depending ...
Undergraduate and first-year graduate students can readily adopt these relatively straightforward experiments.Double fertilization in flowering plants hinges on the pollen tube's (male gametophyte) growth, guidance and acceptance by the female gametophyte within the pistil, a crucial stage for seed ...
of fact, if the astronomical coordinates on Y2K for a solar year called for the calendar at this point to "add a month," it would not only have been inconsistent with what went before it, but it would be wrong. It would call for there to be two leap months added to one year!1...
I have seen people work through exactly what you are describing and they can eventually come out ahead of their peers. But the same amount of effort with a college degree might have let them leap frog their peers through their mid 30s. ...
The outer peri-urban development is typically a leapfrogging manifestation of built-up tracts within farmland expanses and is characterized by low-density, non-contiguous, and automobile-dependent societies [105,145]. An improvement in transport facilities helps to reduce travel time to the nearby ...

While it might have been reasonable to expect trace levels of a broad array of compounds, due to death and replacement of venom gland cells, many of these compounds are 3–6 orders of magnitude more abundant than such anticipated background levels. Accordingly, we identified and semi-quantified...
