A Eu 2+ ‐doped SiO 2 –Al O 3 –CaO–CaF glass was prepared and converted into a transparent ceramic by heat treatment. The crystalline phase its size were determined X‐ray diffraction transmission electron microscopy. scintillation of ions in both under excitation investigated compared with that single‐crystal scintillator.

This paper discusses upper-limb power-assist control using a pneumatic rotary actuator to support shoulder movement and an air cylinder elbow by agricultural workers lifting 30 kg rice bag without inducing low back pain. Surface electromyogram (EMG) signals are used as trigger signals, joint torque is calculated based on the antigravity term of necessary torque, estimated dynamics human approximated link model. Experimental results demonstrate effectiveness proposed control.

For ideal speech communication in public spaces, it is important to determine the optimum level for various background noise levels. However, intelligibility scores, which conventionally used as subjective listening test measure quality of communication, near perfect most everyday situations. this reason, proposed levels spaces by using difficulty ratings. Two kinds were carried out work. The results tests and our previous work [M. Morimoto, H. Sato, M. Kobayashi, J. Acoust. Soc. Am. 116,...

It was shown previously that α-terpineol is the cholagogic principle in cardamom. Two monoterpenoid glucoside, (±)-α-terpineol-2, 3, 4, 6-tetra-O-acetyl-β-D-glucopyranoside (TAG) and (±)-α-terpineol-β-D-O-glucopyranoside (TG), were synthesized order to develop new drugs whose structures are based on those of natural products. The properties these compounds investigated this study. TG administered by oral intraduodendal routes rats showed a significant effect, while TAG little effect. effect...

Purpose To investigate the influence of EDOF IOLs, TECNIS Symfony® (Johnson & Johnson Surgical Vision, Inc.), on visual field sensitivity and to compare IOLs with other kinds IOLs. Methods The subjects included normal fellow eyes patients who underwent Humphrey Field Analyzer (HFA) 30–2 Swedish Interactive Threshold Algorithm Fast within 6 months after cataract due glaucoma or suspected glaucoma. Each parameter HFA was compared among implanted TENIS (EDOF group), diffractive bifocal (bifocal...

In the present work, evaporation rate of PbWO 4 (PWO, powdered crystal) and PbO (powder) in temperature range 700 to 1200°C was measured by thermogravimetric analysis. The log V vs T -1 plot determined be linear dependence PWO found same as that solid state. This shows crystals grown Czochralski method are Pb-deficient a result self-annealing. optical transmittance excitation-emission spectra as-grown annealed Bridgman were also measured. Annealing performed 500 1000°C (isochronal) for 1 h....
