ABSTRACT
The x-ray absorption spectra in metallic W (Tungsten) have been measured above MIII edge using the third generation synchrotron radiation. ALS, Berkeley. Several features caused by multi-electron transitions were detected on MIII in solid phase. [3p4f], [3p5s], and [3p5p] double electron transitions were identified by the Z+1 approximation.
ABSTRACT
A spectrograph has been developed with sufficient efficiency to make high-resolution fluorescence experiments on metalloproteins possible. The resolution of this spectrometer can reach 0.45 eV at 7.1 keV emission energy. The focus images of this multiple curved-crystal array spectrometer are presented. The chemical sensitivity of Kbeta emission spectra can be used to identify chemical states, and the spin-polarized near-edge structure provides a new measure of the spin density. The high-resolution fluorescence metalloprotein studies should become routine with third-generation synchrotron facilities, and the strength of both site and spin selectivity should complement the structural information from other spectroscopies.

The pediatrician continues to devote more time to office evaluation of patients. The office assessment of nutritional status will be extremely rewarding to the physician who acquires several simple measuring devices and who instructs his assistants in the proper use of those devices. The nutritional evaluation of the patient emphasizes the physical examination, anthropometric measurements and the use of laboratory studies. The information gained from these areas may allow for early correction of growth abnormalities before permanent stigma or residuals can develop.

Of 96 ingestions involving safety packaging, 82% involved misuse. The package in some way was unacceptable to the consumer--it was too difficult to open or too difficult to close. Nonacceptance by the elderly was not a significant factor. In only 18% of the safety packaged ingestions, did the child upen the package. The child was more likely to be able to open the screw-cap and the strip-pack. The pop-off and press-lift were not opened by any child but were types misused only by parents. The older child with a record of prior poisoning was most likely to open a safety package. These children would appear to represent a hard core of risk subjects refractory even to safety packaging. Safety packaging has had a dramatic effect on the morbidity and mortality of accidental poisoning. There are two remaining problems that require further study: 1. The analysis of technical factors impeding consumer acceptance and child proofing. The ideal package is so easily handled by the adult that misuse does not occur, but is too difficult for the child to open. 2. The personality characteristics of the safety-package-resistant child. Safety packaging, as implemented by the Comsumer Product Safety Commission, has had remarkable success. Education did not reduce accidental poisoning; safety packaging does. Pediatricians, pharmacists, and toxicologists must work with industry and the Consumer Product Safety Commission to complete the goal of elimination of accidental poisoning.
