Removal of unpleasant odor gases using an Ag-Mn catalyst

Conversions of acetaldehyde and trimethylamine as model unpleasant odor gases were measured over several catalysts. The activities of Ag and Mn₂O₃ were the highest of the catalysts that consisted of a single component. The addition of Ag to manganese oxide enhanced the activity and the durability of the catalysts. The activity of Mn catalyst was improved by the addition of Ag up to 40 atom-%, and the maximum activity was observed at 10 atom-%. Acetaldehyde was considered to be decomposed over the AgMn catalyst by oxidation according to the measurement of reaction products. The oxidation state of silver was maintained on the surface of the AgMn catalyst calcined at 773 K. The amount of oxygen adsorbed on the surface of the AgMn catalyst was about 2.9 times as much as that on Mn₂O₃. These experimental data suggested that manganese oxide supplied oxygen to silver and that the oxidation state of silver was maintained on the surface of the AgMn catalyst.     

A novel biomarker for hyperglycemia, MRX isolated from hydrolysate of glycated proteins

Long-lived proteins can undergo non-enzymatic glycation to form highly crosslinked structures with characteristic fluorescence during aging and diabetes processes. In this paper, a typical fluorophore, named Maillard reaction product X (MRX), was isolated from the hydrolysate of glycated proteins. MRX could be formed by incubation of bovine serum albumin with glucose, followed by acid hydrolysis. The structure of MRX was determined to be 8-hydroxy-5-methyldihydrothiazolo[3,2-alpha] pyridinium-3-carboxylate. MRX was also found to be formed by the incubation of cysteine and arginine with glucose, followed by hydrolysis. We found the formation of MRX in the recently developed genetically diabetic Otsuka Long-Evans Tokushima Fatty (OLETF) rats and compared them with that in the control Long-Evans Tokushima Otsuka (LETO) rats. Significantly higher levels of MRX were observed from the serum (p < 0.005) and urinary protein (p < 0.001) of OLETF rats in comparison with those of LETO rats. MRX must be a potential candidate as a biomarker for hyperglycemia.     

Assessment of the mechanical properties of peripheral arteries in chain saw operators using a photosensor

In order to evaluate the severity of peripheral vascular disorders, and to detect changes in the digital arteries of workers who use chain saws, the mechanical properties of the digital arteries of 22 such workers were examined using a photosensor. The elastic properties and the nonlinearity of digital arteries were assessed through observation of the changes in the vascular volume ratio (V/Vo) against the volume (Vo) at mean blood pressure (Pm). A significant negative correlation was found between age and V/Vo at a transmural pressure of 30 mmHg (V30/Vo), which suggested that V30/Vo tended to decrease with aging. Although it was impossible to calculate V30/Vo for chain saw operators because of the vague changes in the volume pulse wave, this nonlinearity was more clearly observed through changes in the relative vascular volume (V/V40) along with a reduction in cuff pressure (Pc) to 40 mmHg below systolic blood pressure. A group of similarly aged healthy controls and three groups of workers with a different severity of vibration-induced white finger (VWF), i.e., no symptoms of VWF, mild VWF and severe VWF, were classified according to the changes in their V/V40 and the reduction in Pc. The results obtained in the present study suggest that the peripheral vascular disorders in workers using chain saws are due to the opening disturbance of the arteries with nonlinear changes in the peripheral artery, which is related to functional and organic abnormality of the arteries.     

A case-control study on the efficacy and the optimum interval of mass screening for prostatic cancer

PURPOSE: The efficacy and the optimum interval of mass screening for prostatic cancer were investigated by a case-control study. MATERIALS AND METHODS: A matched pairs analysis by 1:5 was conducted between 31 cases of advanced prostatic cancer in stage C and D detected by mass screening and 155 controls of normal subjects selected at random. In all cases and controls, the history of taking part of the mass screening for last 3 years, then the estimates of odds ratios (OR) and 95% confidence intervals (95% CI) were calculated on discordant pairs of the matched analysis. RESULTS: OR to suffer from advanced prostatic cancer was 0.22 (95% CI: 0.07-0.70) in the group to submit to mass screening 1 year ago in comparison with the group not to submit once for 3 years. According to the analysis on the interval of submission to mass screening, the effect of screening to prevent the progression to advanced stages might be valied for 1 year. CONCLUSION: Mass screening for prostatic cancer every year might be efficient to reduce the number of patients progressing to advanced stages.     

Optimal planning for introducing dispersed generating sources in power systems based on an economical viewpoint

This paper discusses optimal planning problems for dispersed generating sources so as to provide a guideline for their introduction to power systems. First, a recursive method is developed from the viewpoint of supplying electric power only where solutions for one unit are superposed. The computational loads are decreased by selecting alternatives of buses based on the so-called penalty factor. However, for effective utilization of dispersed generating sources, it is indispensable to consider their thermal merits in addition to electric power. After applying the Kuhn-Tucker theory to the optimal dispatching problem including boiler fuel costs, thermal values of the dispersed generating units are evaluated quantitatively. Finally, the above-mentioned technique for the optimal planning basically is also effective and is extended into this case. The validity of the proposed algorithms are demonstrated using a real-scale model system.

Thermodynamics of Na2O in the molten CaO-CaF2-SiO2 system

The activity of a few percent of Na₂O in the CaO-CaF₂-SiO₂ system doubly saturated with CaO and 3CaO·SiO₂ has been determined between 1423 and 1623 K by a chemical equilibration technique. The temperature dependence of the activity coefficient of Na₂O may be expressed as follows. {fx553-01} It was found that Henry’s law holds up to 5 mass pct of Na₂O in the flux at 1473 K. The activity of a small amount of Na₂O in the CaO-CaF₂-SiO₂ flux is discussed in comparison with that for the Na₂O-SiO₂ system in terms of their refining characteristics.
