The collisions of translationally hot O(1D) with O2 result in two processes, translational energy relaxation and electronic quenching to O(3P). These two processes were studied in a gas cell at room temperature using the vacuum ultraviolet laser-induced fluorescence technique. The initial hot O(1D) atoms were produced by the photodissociation of N2O at 193 nm, which have average translational energies of 18.1 kcal mol-1 in the laboratory frame. Time-resolved measurements of the Doppler profiles for the hot O(1D) atoms revealed the translational energy relaxation process, whereas the quenching process was investigated by measuring both the decrease of the O(1D) concentration and the increase of the product O(3P) concentration at various delay times after the photochemical formation of the hot O(1D) atoms. From the simulation employing an elastic hard-sphere collision model with a Monte Carlo method, the hard-sphere diameter for the translational energy relaxation process of hot O(1D) by collisions with O2 ...

The effects of oral administration of hot water extract from autologous lysate of Lactobacillus casei (LEx) on the systolic blood pressure (SBP) were studied in spontaneously hypertensive rats (SHR). Oral doses of 10 mg/kg of LEx produced a significant decrease of the SBP of SHR, but LEx had no effect in normotensive rats. The long-term administration of LEx (1 or 10 mg/kg/day) to SHR from 5 to 17 weeks after birth suppressed the development of hypertension. LEx dialysed against distilled water was separated into a polysaccharide fraction (SG-1), a protein fraction (PR-1), and a nucleic acid fraction (NA-1), and SBP-lowering effects of these materials were investigated in SHR at the same dose (10mg/kg). The most effective material of these three was SG-1.

Lithium ion conducting glasses were prepared in the system (0.6Li2S⋅0.4SiS2)-Li3PO4 by twin-roller rapid quenching. The temperatures of glass transition (Tg) and crystallization (Tc) were determined for the glassy samples with 0-40mol% Li3PO4. The conductivity values at 25°C (σ25) were maximized and the activation energies (Ea) for conduction were minimized at the composition with 5mol% Li3PO4; the maximum σ25 value was as high as 9×10-4S⋅cm-1. Since the difference between Tg and Tc was also maximized at the same composition, it was concluded that the doping of small amounts of Li3PO4 improved both the glass stability against crystallization and the lithium ion conductivities.
