N isotope budgeting provides an independent geochemical constraint in this regard...

The density of 15-crown-5 ether (15C5) solutions in the mixtures of N,N-dimethylformamide (DMF) and water (H2O) was measured within the temperature range 293.15-308.15 K using an Anton Paar oscillatory U-tube densimeter. The results were used to calculate the apparent molar volumes (VΦ ) of 15C5 in the mixtures of DMF + H2O over the whole concentration range. Using the apparent molar volumes an...

We present a comparison of new data on n-p -+ ,o”n at 15 GeV/c with polarized and unpolarized single pion photoproduction data. Particular emphasis is placed upon the behavior of the differential cross sections and asymmetries in the forward direction, (-t < m $ 0 (Submitted to Phys. Rev. Letters.) * Work supported by the U. S. Atomic Energy Commission. Studies of single pion photoproduction at...

We report the ionic photoproducts produced following photoexcitation of mass selected IBr(CO2)n , n50 – 14, cluster ions at 790 and 355 nm. These wavelengths provide single state excitation to two dissociative states, corresponding to the A8 P1/2 and B 2 S1/2 1 states of the IBr chromophore. Excitation of these states in IBr leads to production of I1Br and Br1I*, respectively. Potential energy ...

One artifact from my childhood in the 1960’s that I still remember vividly is the series of plastic slidingblock puzzles manufactured by The Roalex Company of Forest Hills, NY (no relation to the maker of fine timepieces). These consisted of a high-quality plastic puzzle glued to a piece of cardboard containing information about the puzzle. Most of their sixty or so different designs were based...

We show that the mixing time for the fifteen puzzle in an n× n torus is on the order of n logn.
