Finite element analysis is used extensively to assess joint replacements, but the majority of these are single sample studies. Recent investigations have suggested that such studies are unable to account for natural inter-patient variation in bone geometry and material property distribution. Recent developments in computer tomography based analyses make(More)
This paper describes the abnormal phenomena caused by almost complete block of connective tube of SPL-14 split/splitless sample injector of Shimadzu GC-14A gas chromatograph. It has been pointed out that if oil compounds with high boiling point are analyzed, periodical clean-up should be done to remove blocking materials for experimental repeatability and(More)
Phospholipids were extracted from the sarcoplasmic reticulum of rabbit skeletal muscle, and separated by high performance thin layer chromatography. The mole fraction of individual phospholipids were determined by assaying phosphorus of each band. Main phospholipids were scraped and extracted, and subjected to esterification by alkaline methanol, and then(More)
Cytosolic pH changes in single thymocytes in the early stages of apoptosis were examined with spectral-crosstalk-improved three-channel real-time fluorescence imaging. Spectral crosstalk was greatly reduced by this improved image processing method. Compared with normal thymocytes, the improved image processing method showed that the cytosolic pH value of(More)
This paper describes new TOF measurement technique for high range resolution of the order of sub-mm or several tens of um. For the distance caliculation, impulse response of photocurrent by means of very short light pulse is used. A draining-only modulation pixel provides high response and lossfree electron integration. The test chip fabricated in 0.11 um(More)
In this paper, a lock-in pixel readout circuits using a high speed lateral electric field modulator with differential charge accumulation for a stimulated Raman scattering imager is presented. The stimulated Raman scattering works by detecting the vibrations in chemical bonds between atoms, and the generated Raman signal after stimulated scattering(More)
