Abstract Periodic leg movements during sleep (PLMS) is a high prevalent disorder of unknown etiology. The disease pharmacologically treated with dopaminergic agonists (i.e. D2/D3 agonists) and opiates. often occur in narcoleptic patients. We observed that canines, like humans, also exhibit jerky, unilateral or bilateral slow sleep. dogs are characterized by repetitive dorsiflexions the ankle, lasting 0.5–1.5 s, at regular intervals 3–20 thus showing similarities to PLMS humans. observation...
Summary Sealing elements (SEs) of fracture plugs have crucial roles to isolate target zones a well in hydraulic fracturing. If the zonal isolation by SE is not adequate, it can result erosion casing. To best authors’ knowledge, effect casing deformation on sealing performance researched or understood. study performance, finite element analysis (FEA) SEs oval casings was conducted this study. Finite simulation degradable plug with three different ovalities (0%, 2%, and 5%) designs (O-ring...
Coherent photoproduction of the neutral-pion and $\ensuremath{\eta}$-meson on deuteron, $\ensuremath{\gamma}d\ensuremath{\rightarrow}{\ensuremath{\pi}}^{0}\ensuremath{\eta}d$, was experimentally studied at incident photon energies ranging from reaction threshold to 1.15 GeV. The total cross section demonstrates a rapid rise below 1 data are underestimated by existing theoretical calculations based quasifree ${\ensuremath{\pi}}^{0}\ensuremath{\eta}$ nucleon followed deuteron coalescence. At...
Measurements of the cross sections are conducted for coherent photoproduction neutral pion and eta meson on d, gamma deutron to pi0 deutron, at incident energy in range reaction threshold 1.15 GeV. A rapidly increasing trend below 1 GeV is observed total section. The data effectively reproduced by theoretical calculations incorporating meson-deutron final-state interactions. However, measured angular distribution d sigma/d Omegad center-of-mass frame (gamma d) rather flat, it differs...
