Generalized Morse and Poschl-Teller potentials : The connection via Schrodinger equation

We present here a systematic and unified treatment to connect the Schrodinger equation corresponding to generalized Morse and Poschl-Teller potentials. We then show that the wave functions and generalized potentials are linked through the Fourier and Hankel transforms, respectively.Comment: 17 pages, 0 figure

The hydrolytic stage in high solids temperature phased anaerobic digestion improves the downstream methane production rate

International audienceThe role of the hydrolytic stage in high solids temperature phased anaerobic digestion was investigated with a mixture of cattle slurry and maize silage with variable ratios (100, 70 and 30% volatile solids coming from cattle slurry). It was incubated for 48 h at 37, 55, 65 and 72 °C. Soluble chemical oxygen demand and biochemical methane potential were measured at 0, 24 and 48 h. Higher temperatures improved the amount of solubilized COD, which confirmed previously reported results. Nevertheless, solubilization mostly took place during the first 24 h. The rate of methane production in post-hydrolysis BMPs increased after 48 h hydrolysis time, but not after 24 h. The first order kinetic constant rose by 40% on average. No correlation was observed between soluble COD and downstream methane production rate, indicating a possible modification of the physical structure of the particulate solids during the hydrolytic stage

A reappraisal of the value of lateral spread response monitoring in the treatment of hemifacial spasm by microvascular decompression

International audiencePrimary hemifacial spasm (HFS) has specific electrophysiological features, like the existence of lateral spread responses (LSRs) to the stimulation of facial nerve branches. The curative treatment of HFS is based on surgical microvascular decompression (MVD), although the outcome of this procedure is not always satisfactory
