β~+-decay half-lives formula even-odd effect<正> We generalize the formula of β~+-decay half-lives [Phys.Rev.C 78 (2006) 014305] to include all availabledata of nuclei far from the β-stable line. Good agreement with experimental data is obtained by taking into accountthe even-odd ...

This study proposes a simple formula to estimate the flexible pavement life (FPL) in balancing the number of converted dynamic axle loads against the design axle loads for the pavement service life of 15 years. The value of the dynamic load coefficient is found by expressing the road surface ...

The Full CLV Formula The second formula involves calculating the net cash flow (that is, both revenue and costs associated with the customer) each year and is generally recognized as the accepted/formal approach to calculating customer lifetime value. Regardless, both formulas are of value and ha...
Even professional athletes—the very best in their sports—face similar challenges. NBA players, for instance, miss more than half of their shots, despite how effortless they make the game look on television. The best hitters in baseball get a hit only about 3 out of 10...
such as giving impromptu speeches in front of strangers. Half the participants were instructed to label their emotions. For instance, “I feel tightness in my chest,”“I feel angst in my throat,” or “I feel heat in my palms.” The other half were not instructed to do anything special...
aGrand Prix racing began in 1906 and became the most popular type internationally in the second half of the twentieth century. The Formula One Group is the legal holder of the commercial rights. With annual spending totalling billions of US dollars, Formula One's economic effect and creation ...
There will always be 101 things to do. I never get through the list and for awhile this used to send me into a hand-wringing state of tizzy-fitting. No more. I see now that more than half of the stuff just doesn’t matter in the grand scheme of things. Do I really need to was...
Making half your mortgage payment twice a month rather than the full payment once a month will end up cutting down your amortization period and saving you a substantial amount of interest. Compounding can work against you, however, if you carry loans with very high rates of interest like ...
