[en] This study investigated the effect of metal ions,such as Fe³⁺, Cu²⁺, Ni²⁺, Cr³⁺ and Zn²⁺, on the photocatalytic oxidation of 2-chlorophenol with illumination of 254 nm and 365 nm UV lights. Different metal ions have individual reduction potentials, and hence, their abilities to capture electrons also differ; the rates of 2-chlorophenol decomposition vary as well. This study was made to explore the relationships between the reduction potentials of different metal ions and their photocatalytic rates of 2-chlorophenol. Results show that when the reduction potential is greater than zero, regardless of illumination wavelength, the reaction rate increases with increasing reduction potentials of the metal ions. When the reduction potential is less than zero, the reaction rates are about the same for illumination of 365 nm or 254 nm UV lights. (author)

[en] The consolidation, undrained strength, and creep properties of remolded illite have been investigated in a laboratory testing program. Samples of remolded illite were consolidated, both thermally and mechanically, and then subjected to undrained triaxial compression or constant stress level creep loading at temperatures of 4, 21.5, 40, 100, and 200⁰C. The material properties which are required to predict the volumetric and deviatoric strain induced by changes in the stress state or thermal field of the sample have been determined. Theoretical and empirical relationships have been developed to calculate the temperature dependent material properties

[en] A refined method for the measurement of protein-bound iodine (PBI) in blood serum was demonstrated by the use of epithermal neutron activation analysis (ENAA). PBI in ammonium sulfate-precipitated serum protein, after epithermal neutron activation was determined by high resolution γ-ray spectrometry. From our results, the PBI concentration was 67.8 ± 2.2 ng/mL. Good agreement was obtained with published data, ranging from 40 to 80 ng/mL, which had been obtained using different analytical techniques. The validity of these techniques for PBI has been born out by a very good accuracy and simplicity without temperature dependence. (Author)

[en] This study assessed the relationship of esophageal radionuclide transit (RT) to diabetic gastroenteropethy (CEP) and autonomic neuropathy (AN). Data were acquired in list mode after an oral dose of 0.5 mCi Tc-99m sulfur colloid in 10 ml of water in the supine position. A modified computer routine was used to calculate: (A) total mean transit time (TMTT) in sec, (B) residual fraction after the first swallow (RF), and )C) retrograde index (RI). Twenty-one patients (pts) with diabetes and 25 normal subjects (N) were studied. Eleven pts belonged to Group 1 with symptomatic GEP and AN; 5, Group 2 with no GEP but with AN; and 5, Group 3 with neither. Abnormal RT mainly occurred in Group 1. RI was the best parameter with respective sensitivity and specificity of 0.91 (10/110 and 0.96 (24/25. RI was abnormal in 10/11 pts with GEP (Group 1), but normal in all 10 pts without GEP (Groups 2 and 3). All 5 pts only with AN (group 2) had normal RI. The authors conclude that esophageal dysfunction is present in nearly all pts with diabetic GEP. However, the presence of AN alone will not explain esophageal transit abnormality
