Orthophosphate (Pi) is an essential macronutrient that plays a central role in virtually all major metabolic processes in plants, particularly photosynthesis and respiration. Many metabolites are Pi monoesters, whereas the phosphoanhydride bonds of compounds such asATP function to transfer energy from the energyyielding process of photo-, oxidative, and substratelevel phosphorylation to the ene...

The H and D atom elimination mechanisms in the photodissociation of jet cooled pyrrole and pyrrole-d1 have been studied by photofragment velocity map imaging. The molecules were excited to the 1 1A2 (pi sigma*) state at lambda = 243 nm and to the 1 1B2 (pi pi*) state at lambda = 217 nm. H/D atoms were detected by (2 + 1) resonance enhanced multiphoton ionization (REMPI) at lambda = 243 nm. The ...

We derive a set of sum rules for threshold parameters of pion-pion scattering whose dispersion integrals are rapidly convergent and are dominated by Sand P-waves absorptive parts. Stringent constraints on some threshold parameters are obtained. PACS Nos.: 13.75.Lb, 11.55.Hx, 11.10.Cd, 25.80.Dj. Work Supported by the Swiss National Science Foundation Address from October 1, 1995: Institut für Th...

High energy heavy-ion collisions are proposed as a novel means to constrain stringently the high density (HD) behavior of nuclear symmetry energy. Within an isospin-dependent hadronic transport model, it is shown for the first time that the isospin asymmetry of the HD nuclear matter formed in high energy heavy-ion collisions is uniquely determined by the HD behavior of the nuclear symmetry ener...

The performance of the Hartree-Fock method and the three density functionals B3LYP, PBE0, and CAM-B3LYP is compared to results based on the coupled cluster singles and doubles model in predictions of the solvatochromic effects on the vertical n-->pi* and pi-->pi* electronic excitation energies of acrolein. All electronic structure methods employed the same solvent model, which is based on the c...

Partial-wave analysis of the pi-+ proton goes to eta meson + neutron and pi-+ proton goes to neutral kaon + Lambda reactions Manoj Shrestha (2012). Partial-wave analysis of the pi-+ proton goes to eta meson + neutron and pi-+ proton goes to neutral kaon + Lambda reactions. We investigate the hadronic reactions πN → ηN and πN → KK via single-energy partial-wave analyses in the c.m. energy range ...

DNA-assisted Förster resonance energy transfer (FRET) between an anthracene-based cyclophane (CP) and mono- and bis-intercalators such as propidium iodide (PI) and ethidium homodimer-1 (EHD), respectively, has been studied using various photophysical and biophysical techniques. The cyclophane and PI exhibited simultaneous binding to DNA at all concentrations studied and showed DNA-assisted FRET...

Protons, AsO;, and NH: are competitive inhibitors of Pi in the oxidative esterification of Pi in chloroplasts. Pi, AsO;, NH:, and other monovalent cations are competitive inhibitors of H+ in the cation-H+ exchange reaction of chloroplasts. Since Pi and protons compete for the same electron-activated fixed anionic sites in chloroplasts, it is proposed that the initial energy-requiring step in ox...

For photocatalytic removal of nitric oxide (NO), two major issues need to be addressed: incomplete oxidation of NO and deactivation of the photocatalyst. In this study, we aimed to solve these two problems by constructing an all-solid-state Z-scheme heterojunction (PI-g-C3N4) consisting of g-C3N4 surface modified with perylene imides (PI). PI-g-C3N4 exhibits significant enhancement in photocata...

Levels of the high-energy phosphate-containing compounds, ATP and creatine phosphate, and of inorganic phosphate (Pi) were measured as a function of position in the cardiac cycle. Measurements were made on isolated, perfused, working rat hearts through the use of gated 31P nuclear magnetic resonance spectroscopy. Levels of ATP and creatine phosphate were found to vary during the cardiac cycle a...
