Soft X-ray photoelectron microscopy used for the characterization of diamond, a-C and CN , thin films
2002
Abstract This article gives an overview about the application of X-ray photoemission electron microscopy (X-PEEM) used for the analysis of carbon thin films. We present the results of an X-ray absorption near edge structure (XANES) study of CVD diamond, a-C and CNx films on Si (100) as well as a defect analysis of a hard disc scratch test. The sp2/sp3 ratio of the carbon films was determined and mapped in the electron micrographs, which show localized defects in the surface.
The metabolic status of internal intensive care patients as indicated by 3-methylhistidine excretion and nitrogen balance
1984
Abstract The metabolic status of 15 intensive care patients receiving a standardized total parenteral nutrition regimen was followed up to 15 days immediately after admission by measuring 3-methylhistidine, total nitrogen, and creatinine excretion. The average 3-methylhistidine excretion was within the normal range during the first 3 days, rising on day 4 and reached a maximum of 70% above normal values on day 5. It declined to within normal range thereafter in most of the patients. Mean values for creatinine excretion remained relatively constant within the normal range throughout the study. During all days 3-methylhistidine was negatively correlated with N-balance. It is concluded that th…
